TRACTION-ENGINE.

i' SPECIFICATION forming part of Letters Patent NO. 327,807, dated October 6, 1885.

Application filed July 30, 1885. Serial No. 173,032. (No model.)

To all whom it may concern.:

Be it known that I, SANDnRs MasoN, of Homer, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Traction-Engines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a side View of my improved traction-engine. Fig. 2 is a similar view seen from the other side. Fig. 3 is a bottom view of the engine. Fig. 4 is a top view of the front portion of the engineframe. Fig. 5 is a front view. Fig. 6 is a rear view, and Fig. 7 is a perspective detail view of the drive-axle and its bevel-gears.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of traction-engines which may be used for driving various kinds of machinery when not used as a traction-engine; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the boiler, which is a usual horizontal boiler having bearings B B, immediately forward of the fire-box C, for the main axle D, and having its forward end supported upon a frame, E, having a circular track, F, provided with a downwardly-projecting flange, G, upon its under side.

The feed-water box His secured under the forward end of the boiler,and has afeed-pipe, I, and a pipe, J, entering it from the feedpump K, and the rear end of the boiler is provided with a platform, L, upon which the engineer may stand, and which is provided at both sides with boxes M for fuel, tools, and other similar purposes.

The steam cylinder N is supported upon brackets O, secured to the upper side of the forward end of the boiler, and the ways P, for the crosshead of the piston-rod Q,are secured to a longitudinal frame-piece, R, the rear end of which is supported by the brackets supporting the cylinder, while its forward end is supported by an upright bracket, S, upon the forward frame E. This bracket and abracket, T, at the other side of the frame,is provided with a bearing, U, in which the drive-axle V revolves, and the said drive-shaft has the connecting-rod of the engine articulated to a crankpin.W, at its end, andis provided with a fly-wheel, X, at its other end.

A bevel-pinion, Y, slides upon a feather, Z, upon the middle of the drive-shaft, and may be secured by a set-screw, A', and this pinion meshesl with a bevel-pinion, B', secured upon the upper end of a short vertical shaft, C', turning in a vertical bearing in the middle of a yoke, D', spanning the frontframe longitudi` nally.

A pinion, E', is secured upon the lower end of this short shaft and meshes with a pinion, F', secured upon the upper end of a short shaft, G', journaled in a vertical bearing, H', at the upper end of one of the brackets I', in the lower ends of which the axle of the front or steering-wheel J' isjournaled, and the lower end of this shaft is provided with a bevel-pin ion, K', which meshes with a cogged rim, L', secured upon one side of the said wheel, so that the said front or steering wheel may be revolved by the drive-shaft. The brackets carrying the said front wheel project downward from a circular frame or fth-wheel, M', which revolves within the fiange G of the front frame, E, and the edge of this fifth-wheel is provided with a series of inclined cogs, N', which are engaged by a worm, O', upon the forward end of a shaft, P', journaled in horizontal bearings upon the side of the boiler, and having a crank-pin, Q', and hand-disk R', upon its rear end, convenient of access for the engineer standing upon the rear platform, so that the engineer, by turning the disk and crankpin, may revolve the worm, and thus turn the fifth-wheel to either side, turning the wheel to either side, and guiding the engine as it progresses, the steering-wheel being propelled by the drive-shaft while it is turned in either direction.

The bevel-pinion Y upon the drive-shaft may be loosened uponV the shaft and slid to one side out of engagement with the bevel-pin ion B',a1lowing the drive-shaft to revolve without driving the steering-wheelwhen the engine is to be used for driving machinery and not as a traction engine.

A bevel-pinion, S', slides upon a feather at IOO the outer end of the drive-shaft, near the fly- :I the steam-engine supported upon the circular wheel, and has a grooved collar, T, upon its inner side, which is engaged by a strap, U', projecting rearward from the outer end of a rack-bar,V, which slides in ways W, formed transversely in the forward side of the bracket T, which forms the bearing for the drive-shaft.

The rack-bar is engaged by a cogged segment at the upper end of a lever, X', pivoted upon the forward side of bracket T, and asimilar segment upon the lower end of this lever is engaged by a segmental disk, Y, upon the forward end of a shaft, Z', journaled in horizontalv bearings A2 upon the side of the boiler, having a hand-lever, B2, at its rear end provided with a spring-lock, G2, which engages a notched segment, D2, at the rear end of the boiler, the rocking of this hand-lever throwing the bevelpinion farther in or out upon the drive-shaft. This pinion meshes, when it isthrown in upon the drive-shaft, with a crown-wheel, E2, upon the forward end of aninclined shaft, F2,which is journaled in suitable bearings, G2, upon the side of the boiler, and the rear and lower end of the shaft is provided with a bevel-pinion, H2,which meshes with a bevel-wheel, I2, turning upon the main axle D, which axle has a traction-wheel, J 2, secured upon one end, and another traction-wheel, K2, turning upon its other end.

The bevel-wheel I2 has anumberof recesses, L, having radial shafts M2, upon which turn bevel-pinions N 2, and these pinions mesh with a bevel-wheel, O2, secured upon the shaft at one side of the bevel-wheel, and with a bevelwheel, P, secured to the inner side of the traction-wheel, so that when the resistance upon one wheel is as great as upon the other wheel the wheels will revolve together; but in case of one wheel being stoppd or reversed, as in turning corners, or in a similar case, the one wheel may either stop or reverse, causing the other wheel to move with a corresponding greater rapidity.

It willthus be seen that the mechanism driving the main axle may be thrown out of gear by tilting the hand-lever and disengaging the pinion meshing with the bevel-wheel at the upperend of the inclined shaft, allowing either the front wheel or steeringwheel to be revolved independently of the drive-wheels, or allowing the drive-shaft to be revolved with out moving the drive-wheels when the engine is used as a motor for machinery.

It will be seen that by having the steeringwheel connected with the driveaxle, so that it will be revolved by the same, the engine will be possessed of greater traction-power than an engine only having the drive-wheels upon the main axle revolved,and the steering-VY wheel being revolved, when it is turned to either side, it will assist in turning the en gine, making it possible to turn the engine on a space equal to its own length.-

By having the boiler supported upon the main axle and drive-wheels, and by having the drive-shaft, its fly-wheel, and a portion of front frame, the weight of the'entire engine is evenly distributed over the three wheels, so that they will all have the same traction-power, and the water-box being placed under the forward end of the boiler, it will be located so that it will not be in the way for any parts of the machine, while it will add to the weight forward of the drive-wheels,and be at a place where the water contained in it may be somewhat heated bythe heat from the boiler above itand from the lire-box immediately to the rear of it.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a traction-engine, the combination of themaiu frame having the forwardly-projecting circular frame formed with the annular downwardly projecting flange, the circular Wheel supporting frame having the rim provided with inclined cogs, the worm engaging the said cogs and secured upon a shaft extending to the rear end of the machine, the shaft journaled above the center of the circular frames and having the pinion at its lower end and suitable connection for revolving it from the driveshaft, and the vertical shaft having a pinion meshing with the central pinion, and journaled in a bearing upon the circular turning-frame,and provided with a pinion meshing with a cogged rim upon the drive-wheel, as and for the purpose shown and set forth.

2. In a traction-engine, the combination of the drive-shaft having a feather near its ilywheel, the bearing for the said shaft having the transverse ways upon its forward side, the bevel pinion sliding upon the feather and having a grooved collar upon its inner face, the cogged rack sliding in the way upon the bearing and having a strapl fitting in the groove of the collar of the pinion, a lever having cogged segments at both ends, one engaging the cogged rack, a shaft having a hand-lever at its rear end and having a cogged segment at its forward end meshing with the lower segment upon the lever, and a crownwheel meshing with the bevelpinion when the latter is slid inward, and secured upon a shaft driving the main axle, as and for the purpose shown and set forth.

3. In a traction-engine, a horizontal boiler supported upon the drive-wheels, a forwardly-extending frame secured to the front end of the boiler and supporting the drive and steering mechanism, said frame and mechanism being supported by a single steeringwheel, and a water-tank secured to the under side of the frontend of the boiler, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
