THE PULSOMETER OR MAGIC PUMPI A NEW ERA IN steam Hydro Engineering, FLUIDS MOVED BY SELF-ACTINC PULSATIONS, iSteam Pumps Supplanted, _____I ~ Piston Rods, Cylinders, Packing, Stuffing Boxes and Air Chambers of no Further Use. The Experience of Ages Set at NaugLt, AND PhILOSOPHY CONFOUNDED. This Apparatus is of vast importance and incalculable value to the Railroad, Steamboat, Mining and Manufacturing Comminity, and all others directly or indirectly interes ed in the use of Steam. It consists only of a single piece of unfinished casting, cylindrical in form, standing upon one end, and( is so constructed internally, that when properly connected with the necessary Steam and Water Pipes, it performs all the wonderful functions of the Steam Pump; raising and forcing a constant stream of water at the same time. It will raise water to the height due a perfect vacuum, and then force the same to a height due the initial pressure of Steam in the Boiler operating it. Having no moving parts it can never wear out, consequently all the vexatious repairs incident to Steam Pump Engineering is obviated. It will Pump Gritty or Muddy Water or even Mud of the consis ency of mortar, without injury to its parts in the least. Hence, its value for Mining and similar situations. It is perpetual in its opera ion, and can never cease its pulsations as long as the conditions of its action are maintained. When adjusted on a Locomotive or Steam Boiler, it not only takes the place of the Feed Pump, but automatically keeps the Water within the Boiler at any desired elevation, operating with absolute certainty, and delivering the water in a constant stream just as needed; thus obviating the primary cause of Boiler Explosions. It can be successfully used in any position and for any purpose within the scope of the Steam Pump, as well as in many situations where a Pump would be practically useless. SEND FP'ORE CIRCIULE AiR.

BOYNTON'S PATENT LIGHTNING SAWS! Also, manufacturer of all kinds of first-class Saws and Saw Handles. The inventor of this Saw claims that its superiority over all others is now established beyond dispute. No other manufacturer has yet ventured to put his Saws in competition with it at the AMERICAN INSTITUTE or elsewhere, and the challenge of $500 for a public trial has nev. r been accepted. It is needless, therefore, to speak of the merits or defects of the various Saws now on the market. The intelligent workman will select the tool that will do the most work with the least labor, and which, at the same time possesses the requisite s rength and simplicity of construction, in which respects this Saw has proved itself far ahead of all others, as will be seen by the Testimonials, which will be mailed to applicants. Awarded Medal of American Institute, over all competitors, Nov. 1872. These Saws have also been highly spoken of in the following well known papers, copies of which can be seen at the office of the inventor, viz: Scientific American," "American Artizan," "New York Tribune," "' New York World," " Christian Union," " Christian Radical," " Examiner and Chronicle," "American Agriculturist " " Hearth and Home," "Iron Age," " Liberal Christian," "Baptist Union," "Kansas Tribune," "Davenport (Iowa) Gazette," " Davenport Democrat," " Moore's Rural New Yorker," " New York Evangelist," " New York Observer," " Independent,"' The Western Rural," "Chicago Standard," and many others. BOYNTON'S CROSS-CUT SAWS In quality of material are fully _ equal to any in the market, a d each blade is subjected to a rigid GT E inspection before leav ng the factory. They are made from r 4 to io feet in length. NOV.2 7.866. JAN. 14.1868 CA1OI1T0N. JULY25867. _ aLY7. As these Saws have been nEW YO RK largely imitated, (but all omitting some essenial principal,) purchasers should be very careful to buy none but those having the name and trade mark of E. M. Boynton, with the $500 challange and directions for filing, using, &c., etched on them. BOYNTON'S ONE-MAN CROSS-CUT SAW I s A.i I It i........ ";: II/II l'"sB~ N I;.'

COLES, SOLE PROPRIETOR AND MANUFACTURER OF Patent Tallow Packing for Car Jollrnals, TALLOW LUBRICATOR AND OIL FOR MARINE AND STATIONARY ENGINES,. Superintendents, Master Mechanics and Engineers of many prominent Railway Companies, who have tested the Paten t'Tallow lPaelring for Car Journals, have expressed to me in writing, surprise and satisfaction at its performance, and many of them pronounce it superior to any article heretofore introduced to them for Lubricating Purposes, and as a RELIABLE PREVENTIVE OF HOT AXLES. AADE WA ITS OHARACTERISTICS ARE: It excludes dust from the journal. It causes the brasses to wear level. It can be used in any kind of boxes. It cannot be spilled out. It is not affected by difference of climate. It lubricates more thoroughly. It requires very little labor and attention. It is considerably cheaper than any other good lubricating material The TALLOW LUBRICATOR for Marine and Stationary Engines, and MACHINE OIL, possess advantages over every other similar compound. I wish to secure patronage rpainly upon the merits of my materials, therefore, do not here present copies of the many testimonials to be seen at my office from parties who have extensively tested and used the same.

" 230 TEMPERING GRAVERS AND DRILLS. A watchmaker in Gosling, by the name of Schussleder, has recently published his method of hardening gravers and drills, which he claims renders them almost as hard as the diamond. He first heats the tool to a white heat, and then presses it into a stick of sealing wax, leaves it but a second there, and then sticks it into the wax in another place. This operation is rapidly repeated, until the graver is too cool to enter the wax. Drills tempered in this manner will pierce the hardest steel tempered in the usual manner. In turning or drilling, the tool is moistened with oil of turpentine. :22 BUYERS' GUIDE, FOR RAILWAY OFFICERS. PHILLIPSBURG MANUFACTURING CO. NEW YORK OFFICE, 23 DEY STREET. WORKS AT PHILLIPSBURCI N.

The staves may be about 21/ ins. thick for the smaller ones; to 4 or 5 ins for the largest. The bottoms may be the same. The staves should be planed by machinery to suit the curve precisely. Nothing is then needed'between the staves to produce tightness. A single wooden dowel is inserted betweeneach two near the top, merely to hold them in place while being put together. The bottom is dowelled together, and simply inserted into a groove very accurately cut, about an inch deep, around the inner circumference of the tub, at a few inches above the bottoms of the staves. One of 20 feet diameter, and 12 feet deep, may have 9 hoops of good iron, placed several inches nearer together at the bottom of the tank than at the top. Their width 3 inches; the thickness of the lower two, 14 inch; thence gradually diminishing until the top one is but half as thick. The lower two are driven close together. These dimensions -will allow for the rivet-holes for riveting together the overlapping ends; and for a moderate strain in driving the hoops firmly into place. Three rivets of M/ inch diameter, and 3 inches apart, in line, are sufficient for a joint of a lower hoop. One of 34 feet diameter, 17 deep, may have 12 hoops; the lower ones 4 inches by Y/; with three X4 inch rivets to a lower hoop-joint. The bottom planks of the tank must bear firmly upon their supporting joists, or bearers. A tank must have a waste pipe for preventing overflow, and a discharge or feed pipe 7 or 8 inches diameter, in or near the bottom. The inner end of the discharge pipe is covered by a valve, to be opened at will by the engine man, by means of an outside cord and lever. To its outer end is generally attached a flexible canvas and gum-elastic hose about 7 or-8 inches diameter and 8 or 10 feet long, through which the water enters the tender-tank. Or, instead of a hose, the feed-pipe may be prolonged by a metallic pipe, or nozzle, sufficiently long to reach the tender; and so jointed as, when not in use, to swing to one side, or to be raised to a vertical position. 26 t3YSER'S GIJI)E, POR RAILWAY OFFICERS.

RUBBER CAR SPRINGS, To resist actual compression and bulging, should be used in layers, with inter vening division plates; if used in bulk, should have retaining rings to preven bursting. The duration of spring depends, of course, on its quality. Pure rubber is of little use; it must be vulcanized. It is adulterated with plumbago, though in best springs as much as 40 per cent. foreign substances are used-principally sulphide of lead and soapstone. WEIGHT OF RUIBBEt cAR SPRINGS.

The wearing of cast-iron surfaces exposed to sliding friction can be almost wholly prevented by tempering the surface with a mixture of 21 1-10 pints of water, 30y/ pounds of sulphuric acid, and 1,003 grains of nitric acid. The article should b e heated to a cherry-red, and protected from the oxidizing effect of currents of air by a sheet-iron box. The process is especially adapted to the hardening of bearings of axles. which, while much cheaper than those of the usual alloy, will, when regularly ubricated, last as long, even when there is great rapidity of motion.

The velocity of wind-mill sails, so as to produce a maximum effect, is nearly as the velocity of the wind, their shape and position being the same. 2. The load at the maximum is nearly, but somewhat less than, as the square of the velocity of the wind, the shape and position of the sails being the same. 3. The effects of the same sails, at a maximum, are nearly, but somewhat less than, as the cubes of the velocity of the wind. 4. The load of the same sails, at the maximum is nearly as the squares, and their effect as the cubes of their number of turns in a given time. 5. When sails are loaded so as to produce a maximum effect at a given velocity, and the velocity of the wind increases, the load continuing the same —First,, the increase of effect, when the increase of the velccity of the wind is small, will be nearly as the squares of those velocities; Secondly, when the velocity of the wind is double, the effects will be nearly as 10 to 27'2; Thirdly, when the velocities compar, d are more than double of that when the given load produces a maximum, the effects increase in nearly the same r.atio of the velocity of the wind. 6. In sails where the figure and position are similar, and the velocity of the wind the same, the number of revolutions in a given time will be reciprocally as the radius or length of the sail. 7. The load, at a maximum, which sails of a similar figure and p: sition will overcome at a given distance from the centre of motion is as the cube of the radius. 8. The effects of sails of similar figure and position are as the square of the radius. 9. The velocity of the extremities of Dutch sails, as well as of the enlarged sails, in all their usual positions when unl aded, or even loaded to a maximum, is considerably greater than that of the wind. Rule for the Angles of the Sails. (Molesworth.) A = Angle of the sail with the plane of motion at any part of the sail. R = Total radius of sail in feet. D = Distance of any part of the sail from the axis. 18 D2 A = 23~ - R2 If the radius of the wid mill sails be divided into six equal parts, the angles at each of those parts will be as follows, reckoning from the axis: Distance from axis.......................... 1-6 2-6 3-6 4-6 5-6 tip Angle of sail with axis................. 6720... 69 71~... 750... 79Y25 850i Angle of sail with plane of motion... 2's.. 21.182... 15... 102 5 Axis of shaft of wind mill with horizon...............= 8 on level ground. 4" " i' " i............ = 15~ on high exposed positions.

TENT TRIPLE-ACTION These Bellows are superior to all others now in use. = They can be used either in single or double action, for light or heavy work as required. They maintain a steady and continuous blast, the air being forced into the chest both at the up and down stroke. The strength of blast obtained is double that of the ordinary bellows of the same dimensions. They work easily. While the blast is double, the power required to work them is no more than that of a common bellows. Being fully rigged and geared, ready for work, and easily moved from place to place, they are very convenient for railroad, mining, and other purposes where portable bellows are required. They economize space, occupying only half the room of an ordinary bellows. These bellow s come to hand at once. A good blast is obtained at the first stroke, and no time or labor is lost, as in the old single-action bellows, in getting up a good blast. They can be made of any size and shape, to suit all requirements. They are the cheapest bellows in the world. With all the advantages of double-action, they cost no more, power for power, than the common single action of same quality. le'or further;articulars send for descriptive circular and price list. 586 WATER ST., near Montgomery, NEW YORK.

L-What proportion of its load on level will engine haul on grade of 20 feet per mile? Look for 20 foot grade at top, follow down perpendicular line to curve, and for percentage look at left hand on horizontal line intersected by the curve. Answer.-50 per cent. Example II. —If an engine's maximum load on 20 foot grade is 200 tons, what is its capacity on 40 foot grade? The diagram gives engine on 20 foot grade 50 per cent. of its capacity on level. Then, 200 tons being 50 per cent., the maximum load on level is 400 tons. The percentage shown on 40 foot grade is 30, and 30 per cent. of 400 gives Answer, 120 tons. This Diagram supposes track to be straight and in,ood order; the load is to be started on grade; the level is supposed to be absolute, though 5 or 10 feet to the mile is as near a level as is often found in practice. Grades of 500 feet per mile can be overcome by engines working by adhesion alone on good T rail. Tenders must be reckoned as a part of the trait, 130 BUYERS' GUIDE, FOR RAILWAY OFFICERS. GEO. 1.

(aswel.) TEMPERING STEEL. (Hfaswell.) Steel in its hardest state being too brittle for most purposes, the requisite strength and elasticity are obtained by tempering-or letting down the temper, as it is termed-which is performed by heating the hardened steel to a certain degree and cooling it quickly. The requisite heat is usually ascertained by the color which the zurface of the steel assumes from the film of oxide thus formed. The degrees of heat to which these several colors correspond are as follows: At 4300, a very faint yellow fSuitable for hard instruments; as hammer-faces, At 4500, a pale straw color.. drills, &c. At 470~, a full yellow.......... For instruments requiring hard edges without elasticAt 4900, a brown color....... ity; as shears, scissors, turning tools, &c. At 5100, brown, with purple spoA t 510., brown, with purple......... For tools for cutting N,ood and soft metals; such as At 5380, purple................. plane-irons, knives, &c. At 5500, dark blue.............. (For tools requiring strong edges without extreme At 5600, full blue............. hardness; as cold-chisels, axes, cutlery, &c. At 6000, grayish-blue, verg J For spring-temper, which will bend before breaking; ing on black................... as saws, sword-blades, &c. If the steel is heated higher than this, the effect of the hardening process is destroyed. 144 BUYERS' GUIDE, FOR RAILWAY OFFICERS. ROGERS & CO.

The single-riveted are estimated at.5 the resistance of the plates, and the staggered riveted at.65. Such allowances for the resistance and wear of the plates, oxydation, etc., are to be wrade, as the character of the metal, the nature of the services, and the circumstance of using fresh or salt water, etc., will render necessary. In riveted plates, it is customary in practice to estimate the safe tensile resistance of the metal of a boiler or tube, when exposed to salt-water, at one-fifth of its ultimate resistance or bursting pressure; and, when exposed to fresh-water alone, at one-fourth of it, 154 lBUYERS' CGUIDE, FORL 1RAILWAY OFFICERS.

(Haswell.) The Pitch Line of a wheel, is'-the ci cle upon which the pitch is measured, and it is the circumterence by which the diam'eter, or the velocity of the wheel, is measured. The Pitch tis the arc of the ci cle of the pitch line, and is determined by the number of the teeth in the wheel. The True Pitch. (Chordial), or that by which the dimensions of the tooth of a "wheel are alone determined, is a straight line drawn from the centres of two contiguous teeth Upon the pitch line. The Line of Citres is the line between the centres of two wheels. The Radius of a *heel is the semi-diame:er running to the periphery of a tooth. Thb Pitch Radius is the semi-diameter running to the pitch line. A Mortice Wheel, is a wheel constructed for the reception of teeth or cogs, which are fitted into recesses or sockets upon the face of the wheel A wheel which impels another is termed the Spur, Driver or Leader; the on impell d is the Pinion, Driven or Follower. A s ries of wheels in conn ction with each other is termed a Train. When two wheels act upon one another, the greater is termed the Wheel, an the losser the Pinion. When a Pinion is driven by a wheel, the number of teeth in the pinion shrc.l l not be less than eight. When a Wheel is driven by a pinion, the number of teeth in a pinion should not be less than ten.'ihle Number of teeth in the wheel should not be divisible by the number of teeth in the pinion without a remainder This is in order to present the saine teeth coming together so often as to cause an irregular wear of their faces.

To compute the Number of Teeth in a Pinion or Follower to have a given Velocity. RULE. —Multiply the velocity of the driver by its number of teeth, and divide the product by the velocity of the driven. Example.-The velocity of a driver is 16 revolutions, tbe number of its teeth 54, and the velocity of the pinion is 48; what is the -number of its teeth? 16 X 54 + 48 = 18 teeth. 2. A wheel having 75 teeth is making 16 revolutions per minute; what is the number of teeth required in the pinion to make 24 revolutionsiu the same tine? 16 X 75.-+ 24 = 50 teeth To Compute the Diameter of a Wheelfor a given Pitch and Number of Teeth. RULE.-Multiply the diameter in the following table -for the number of teeth by the pitch, and the product will give the di. meter at the pitch circle. Example.-What is the diameter of a wheel to contain 48 teeth of 2.5 in~. pitch? 15.29 X 2.5 = 38.225 ins. To Cbmpute the Pitch of a Wheel for a given Diameter and number of Teeth. RvUL.-Divide the diameter of the wheel by the diameter in the table (page 171) for the number of teeth, and the product will give the pitch. Example.-What is the pitch of a wheel when the diameter of it is 50.94 inches, and the number of its teeth 80? 50.94 + 25.47 = 2 ins. To Compute the Number of Teeth of a Wheel for a given Diameter and Pitch. RULE. —Divide the diameter by the pitch, and opposite to the quotient in the table (page 171) is given the number of teeth. 1 70 BUYERS' GUIDE, FOR RAILWAY OFFICERS. T. S. RAY. C. A. MIAR VIN.

(Scientific American.) Nitric acid will produce a black spot on steel; the darker the spot the harder the steel. Iron, on the contrary, remains bright if touched with nitric acid. Good steel in its soft state has a curved fracture and a uniform grty lustre; in its hard state a dull, silvery, uniform white. Cracks, threads, or sparkling particles denote bad quality. Good steel will not bear a white heat without falling to pieces, and will crumble under the hammer at a bright red heat, while at a middling heat it may be drawn out under the hammer to a fine point. Care should be taken that before attempting to draw it out to a point, the fracture is not concave, and should it be so the end should be filed to an obtuse point before operating. Steel should be drawn out to a fine point and plunged into colp water; the fractured point should scratch glass. To test its toughness, place a fragment oil a block of cast-iron; if good it may be driven by the blow of a hammer into the cast-iron, if poor it will crush under the blow. A soft, tough iron, if broken gradually, gives long silky fibres of leaden-grey hue, which twist together and cohere before breaking. A medium even grain with fibres denotes good iron. Badly refined iron gives a,short blackish fibre on fracture. A very fine grain denotes hard steely iron, likely to be cold-short and hard.Coarse grain with bright crystallized fracture or discoloured spots denotes coldshort, brittle iron, which works easily when heated and welds well. Cracks on the edge of a bar are indications of hot-short iron. Good iron is readily heated, is soft under the hammer, and throws out few sparks.

Dissolve a teaspoonful of alum in a quart of warm water. When cold, stir in as much flour as will make it the consistency of thick cream, being particular to beat up all the lumps; stir in as much powdered resin as will stand on a dime, and pour in a few drops of oil of c oves to give it a pleasant odor. Have on the fire a teacupful of boiling water; pour the flour mixture into it, stirring well all the time. In a few minutes it will be of the consistency of mush. Pour it into an earthen or china vessel; let it cool; lay a cover on, and put it in a cool place. When needed for use, take out a portion and soften it with warm water. Paste thus made will last twelve months. It is better than gum, as it does not gloss the paper, and can be written upon. 182 BUYERS' GUIDE, FOR RAILWAY OFFICERS.

The Tri-Nitro-Glycerin manufactured under the Mowbray Patent is safer to handle, has 30 per cent. more explosive force, and is a more stable compound than can be made by the Nobel process. Our fuses are safe to handle, and are sure fire. I import from Singapore, selected Gum Gutta Percha, having been driven to this by reason of the adulterated Gum in the market, and insulate copper wire by means of machinery (the result of many years' investigation) with the sole view to render blasting with Nitro-Glycerin perfectly safe and O- per cent. cheaper than with powder. Proved to have more than double the force in blasting over Dualin, Dynamite, Giant Powder, and other secret preparations composed of inferior Nitro-Glycerinl with inert matter. We send experienced men to instruct the miners in using it economically and safely, and have never failed in giving satisfactory results, during the past four years, BUSINESS DIRECTORY, ETC. 183 Picks.

" 144 INSTRUCTIONS FOR HANDLING AND USING MOWBRAY'S TRI-NITRO-GLYCERIN. 1. Handle carefully, avoiding a sudden jar or concussion, and be very careful, if any is spilt outside the can, to avoid striking it against any hard substance. 2. When solid, thaw out by placing the cans in a tub of warm water, not hotter than the wrist can bear, first pouring warm water into the can, and always remove the can before adding more hot water to the tub. 3. To fill Cartridges, &c.-Hold the cartridge to be filled over a tray, say two feet by three feet, the bottom of which should be * overed with Plaster of Paris (which will not readily explode when saturated with Nitro-Glycerin.) The soiled Plaster of Paris-should be frequently renewed. 4. If the Nitro-Glyceriu in a liquid state is kept in store or magazine for some time, the c rk should be loosely inserted, and a pint of cold water poured in each can, to be frequently poured off and replaced with fresh cold water in warm weather, taking care to retain the bladder under the cork. It is preferable, when ice can be procured, to congeal the Nitro-Glycerin. 5. Use Funnels (gutta-percha if it can be had) for filling water holes. Under no circumstances whatever attempt to tamp the drill holes; it is unnecessary, and may kill the uan who attempts it. 6. Hot irons to warm the water, or soldering the cans, will be sure to cause explosions. 7. Never sledge or attempt drilling in a hole or seam where Nitro-Glycerin has been spilled; fire an exploder, which will effectually clear it up. 8. Never pour Nitro-Glycerin into a hole unless perfectly sure that it is a sound hole, or will hold water; it' seamy always use cartridges. 9. To obtain the best results with Nitro-Glycerin, drill deep holes, 6 feet or more. Use powerful expl,ders and well insulated wires, It is cheaper to fire by electric battery with simultaneous explosion, than to fire several holes with tape fuse. 10. Look out after a blast for any unexplo'ed cartridges lying around. 11. Never allow any but the most careful persons to handle or have charge of the Nitro-Glycerin, and insist upon the use of every precaution to prevent an accident or explosion. 12. Never allow empty Glycerin cans to be used for any other purpose, but destroy them by a fuse aun exploder, or building a fire under them, first, however, removing them to a safe distance. 13. Examine your cans from time to time, and notice if, at the level of the Nitro-Glycerin, any pin-ho'es have eaten through; in such case procure a new can, or stone jar, and empty the contents out, not trusting your hold to the upper part of the can, lest it may give way. 14. When solid, or congealed, it is absolutely safe; if possible, therefore, any surplus should be stored surrounded with ice, since no explosion can take place whn it is solid. 184 BUYERS' GUIDE, FOR RAILWAY OFFICERS.

Rule 1st-To find elasticity of a given steel-plate spring; Breadth of plate in inches multiplied by cube of the thickness in /; inch, and by aumbfr of plates; divide cube of span in inches by prod ct so found, and multiply by 1.66. Result, equal elasticity in ], of an inch per ton of load. Rule 2d-To find span due to a given elasticity, and number and size of plate; Multiply elasticity in sixteenths per ton, by breadth of plate in inches, and divide by cube of the thickness in inches, and by the number of plates; divide by 1.66 and find cube root of the quotient. Result, equal span in inches. Rule 3d-To find number of plates due to a given elasticity, span and size of plates: Multiply the cube of the span in inches by 1.66; multiply the elasticity in sixteenths by the breadth of the plate in inches, and by the cube of the thickness in sixteenths; divide the former product by the latter. The quotient is the number of plates. Rule 4th-To find working strength of a given steel-plate spring: Multiply the breadth of plate in inches by the square of the thickness in sixteenths, and by the number of plates; multiply also the working span in inches by 11.3; divide the former product by the latter. Result, equal working strength in tons burden. Rule 5th-To find span due to a given strength and number, and size of plate; Multiply the breadth of plate in inches by the square of the thickness in sixteenths, and by the number of plates; multiply, also, the strength in tons by 11.3; divide the former product by the latter. Result equal working span in inches. Rule 6th-To find the number of plates due to a given strength, span and size of plate: Multiply the strength in tons by span in inches, and divide by 11.3; multiply also the breadth of plate in inches by the square of the thickness in sixteenths; divide the former product by the latter, Result, equal number of plates. The span is that due to the form of the spring loaded. Extra thick plates must be replaced by an equivalent number of plates of the ruling thickness, before applying the rule. To find this, multiply the number of extra plates by the square of their thickness, and divide by the square of the ruling thickness; conversely, the number of plates of the ruling thickness to be removed for a given number of extra plates, may be found in the same way. 202 BUYERS' GUIDE, FOR RAILWAY OFFICERS.

General Rule for the Computation of Stlate. (Furnished by the Penrhyn Slate Co.) From the length of the Slate take three inches, or as many as the third covers the first; divide the remainder by 2, and multiply the quotient by the width of tbhe slate, and the product will tie the number of square inches in a single slate. Divide the number of square inch s thus procured by 144, the number of square inches in square foot, and the quotient will be the number of feet and inc es required.

A substance known as "leather glue" is prepared by mixing ten parts of sulphide of carbon with one of oil of turpentine, and adding enough gutta-percha to thicken the mass. The leather surfaces to be united must be freed from oil, which is accomplished by subjecting them to pressure by laying the leather upon blotting paper and applying a hot iron. After tracking together the edges to be joined with the cement, they are to be kept under pressure until the glue is entirely dry. 208 BUYERS' GUIDE, FOR RAILWAY OFFICERS. S4 - — si — e2 ACp In all other Band Sawing-Machines the saw is placed outside of the frame and column which support the driving parts, exposing the Saws to injury from handling lumber about them, also rendering them extremely dangerous to the operator. The main feature in this Machine has been to produce a Band Saw, perfectly safe to the operator, and fully protected from injury to the Saw, combining neatness and utility in all its parts. The Saw is placed to run upward near the column, under the top arch, over the upper or tension pulley and down near the front frame and behind the guide-bar, which can be adjusted up and down to the required height for the work to be done. It also wums through a superior adjustable guide, above and below the work, and a guide Qr the OolUad, gulding equally well all widths of Saws. parts Th a spae ornupadna h oun ndrtetpacoe h uppr o tndo piedanddow nar hefrot fam an bein th g idebr hc Ca eajse pan ont h eure egtfrtewrkt edn.I d through asueiradutbeudeabvan eo tewr nd aieB the tolgidigeq~al o"lalwdtso av S1SIN0SS DtEOdTORT, EJC. 209 Sash Weights.

Furnished by J. T. & R. H. Plass, New York. File the ends of the band on opposite sides, to form two wedged-shaped ends, having a lap of say 34 inch long, which, when laid with their beveled and filed sides together shall form a good joint of the same thickness as blade. Now clamp the ends on a piece of board, with the back of the blade toward you, with the lap brought fair together, and see that the back of the blade is straight. Cut a piece of "silver solder," large enough to cover the lap, lay it between the lapped portion with a little pulverized " borax." Now, having a piece cut out of your board, say three inches wide,,irectly under your lap, heat your soldering tongs to a bright " cherry red," and hold them pinched firmly on tht lap until the solder flows freely from under the joint, then cool off the tongs and soldered portion of saw by pouring water upon the same, without relieving the pressure, until nearly cold. Try a file on both sides of the blade, and should it be harder than the other part of the blade, reheat your tongs a little, and draw the temper by pressing the tongs upon the hard portion of blade till partially heated, but not upon the lap, as it will weaken your joint. File off the solder and joint to the same thickness as other parts, and the soldering of your band is completed. CEMENT FOR LEATHER BELTING. Take of common glue and American isinglass, equal parts: place them in a boiler and add water sufficient to cover the whole. Let it soak 10 hours, then bring it to a boiling heat, and add pure tannin until the whole becomes ropey or appears like the white of eggs. Apply it warm. Buff the- grain off the leather-where it is to be cemented; rub the joint surfaces solidly together, let it dry a few hours, and it is ready for practical use; and, if properly put together, it will not need riveting, " the cement is nearly of the same nature as the leather itself, 210 BUYERS' GUIDE, FOR RAILWAY OFFICERS.

(Hamilton.) lIorse-power of a belt equals velocity in feet per minute, multiplied by the width-the sum divided by 1000. One inch single belt, moving at 1000 feet per minute = 1 horse-power. Double belts about 700 feet per minute, per 1 inch width = 1 horse-power. For ~couble belts of great length, over large pulleys, allow about 500 feet per minute per 1 inch of width per horse-power. Power should be communicated through the lower running side of a belt; the the upper side to carry the slack. Average breaking weights of a belt, Y6 X 1 inch wide. Leather, 530 lbs.; 3-ply rubber, 600 lbs. I he strength of a belt increases directly as its width. The co-efficient of safety for a laced belt is- Leather = 1 breaking weight.
