TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 388,692, dated August 28, 1888.

Application filed March .29, 1888.

v the accompanying drawings, is a full, clear,

and exact description.

This invention consists in a novel organization of a traction-engine designed for driving 'thrashingmachines, 850., and which is provided with means of superior capacity of ex erting the tractive power of the engine, and is also adapted for drawing objects toward the engine, all as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a traction-engine embodying my invention. Fig. 2 is a plan view taken below the boiler of the engine and showing the drivingshaft and its connection with the propelling mechanism. Fig. 3 is an enlarged vertical transverse section on line a: m, Fig. 1. Fig. 4 isa longitudinal section of the drivingshaft, and Fig. 5 is an enlarged longitudinal section of one of the propelling-legs.

Similar letters of reference indicate corresponding parts.

A represents a steam-engine of any suitable and wellknown type, mounted on carryingwheels IV W, to allow it to be transported on highways or on the ground from place to place, as may be desired.

N represents a stout rectangular frame, preferably formed of metal,and rigidly secured in a horizontal position to the lower portion of the exterior of the boiler A. On suitable bear ings on the said frame are carried longitudinally-movable bars B B, arranged lengthwise of the engine A. Said bars I prefer to formof wrought-iron or steel of I shape in crosssect-ion, and in order to obviate undue friction I form the aforesaid bearings of hangers or brackets Z l, which are rigidly'secured to the frame N, and have pivoted to them rollers m m, upon which the-bars B B ride, and rollers 12 a are interposed between the topof the bars and frame N, as shown in Fig. 3 of the drawings. Said bars receive reciprocating motion from the engine by the driving-shaft G, which is arranged crosswise of the engine or at right angles to the bars B B, and has affixed to one Serial No. 268,096. (No model.)

end a crank, P, which is connected with the piston-rod o of the engine by a connection-rod, in the usual and well-known manner. The opposite end of said driving'shaft has secured to it a driving-pulley, O, by which to transmit motion to a thrashing machine or other machines usually driven by portable engines. To the central portion of the said drivingshaft is rigidly attached a worm-gear, H, for the purpose hereinafter explained, and on each end of said gear is a clutclrface, D. On the end portions of the driving-shaft are loosely mounted sleeves E E, which are confined longitudinally by collars r r, fastened to the shaft at opposite ends of each sleeve, as shown in Fig. 4 of the drawings. The exterior of the end portion of each sleeve adjacent to the clutch-face D is provided with a spline, h, and on said portions of the sleeves slide clutches F F, provided with grooves, through which the splines extend,and thus confine said clutches circumferentially on the sleeves, the clutches being adapted to interlock with the clutch-faces D D, and when so interlocked motion is transmitted from the driving shaft to the sleeves E E. l

Suitable levers, R R, for shifting the cl utches are pivoted to suitable supports, H, on the frame of the engine, and preferably a rod, B, for operating said levers is connected at one end to said levers and extended to the rear end of the engine, to be convenient of access for manipulation by the engineer in charge. To the outer ends of the sleeves are rigidlysecured eccentrics a a, with which are connected the longitudinal movable bars B B by pitmen b b. By throwing the clutches F F into engagement with the clutch-faces D D the sleeves E E, with their eccentrics a a, receive rotary motion when the engine is in motion, and the eccentrics impart reciprocating motion to the bars B B by means of the pitmen b b. The eccentrics are disposed at such position inrelation to'the axial center of the shaft as to move the bars B B respectivelyin opposite directions.

To each of said bars I hinge a set of propellinglegs, L L, which are of sufficient length to cause them, when resting with their feet on the ground, to lie obliquely or inclined in opposite direction from that in which the engine is to be propelled; and in order to allow the engine to be propelled backward as well as forward I incline one or more propelling-legs on each bar 13 in opposite direction from the remainder of the legs, and preferably connect the said oppo sit-ely-disposed legs with each other in such a manner as to cause the rearwardly-inclined legs,when resting on the ground, to lift the forwardly-inclined legs, and vice versa. By setting the engine in motion the reciprocating bars B B cause the legs L L, which bear with their feet on the ground, to push the engine in opposite direction.

In order to relieve the propelling-legs from undue strain and concussion, I cushion the Sam e, preferably by forming the leg of a sleeve, 6!, which is closed at one end and receives through its opposite end the free end of the stiff limb d, which is hinged to the bar 13. A spiral spring, 0, is interposed between the inner or closed end of the sleeve and adjacent end of the limb d, and a pin, f, projects from the side of the said limb and into a longitudinal slot, 8, in the sleeve d, to unite the sleeve with the limb, as illustrated in Fig. 5 of the drawings. The foot 6 of the leg I prefer to form of a separate piece detachably connected to the leg, to allow the foot to be readily renewed or repaired when required. Said foot I provide with a ventiduct, c, to admit air under the foot, and thus allow it to be readily released from the ground.

For raising the pr0pelling-legs from the ground when desired I employ cables or chains i 2', running lengthwise beneath the boiler of the engine, and provided with branches '5 t", which are connected to the respective legs. One end of each cable or chain is wound upon a drum or Windlass, K, by which to control the movement thereof.

In a socket-,t,on abrace,T, rigidly secured to the engineframe, is stepped a shaft, on which arejournaled a drum, J, and a gear-wheel, I, fastened to said drum. The hub of said gearwheel projects through a slot,u,in a horizontal bracket, V, rigidly secured to the under side of the boiler, said slot allowing the gear-wheel to be moved toward and from or in and out of mesh with the worm H on the driving-shaft O, hereinbefore described. To retain the said gear-wheel either in or out of mesh with the worm,as may be desired, I provide the bracket V with transverse slots 1) 1;, respectively in front and rear of the hub of the gear-wheel, and insert into the requisite slot a key, 20.

On the drum J is wound one end of a cable or chain, U, the opposite end of which is ex tended to the rear end of the engine, and can be drawn farther in said direction to allow it to be connected to an object desired to be moved toward the engine. In this operation the rearwardly-inclined legs L L are brought to bear on the ground to brace the engine and confine it in its position, and the clutches F I* are thrown out of connection with the clutchi'aces D D and the gear-wheel I thrown into engagement with the worm H. Then by starting the engine the driving-shaft O imparts rotary motion to the drum J, and by winding thereon the cable or chain U the object attached thereto is drawn toward the engine. Said cable or chain may also be employed for drawing the engine up a steep hill by running the cable or chain ahead and tying it to a stationary obj cot.

I am aware that prior to my present invention drums or windlasses with ropes or chains extended therefrom have been connected to locomotives for the purpose of either drawing the same up an ascending grade or drawing the train of cars to the locomotive; but in such cases the Windlass was operated either by a rod connecting the crank of the Windlass with the crankpin of the driving-wheel of the locomotive or by pistons in steam-cylinders sepa rate and distinct from the usual steam-cylinders which contain the pistons furnishing the power for the driving-wheels. Neither ofsueh prior devices is adapted for a traction-engine designed to travel over an ordinary wagonroad and to furnish power for operating thrashing-machines and other machines remote from the engine, inasmuch as such latter engines are provided with a driving-shaft separate and distinct from the axles of the carryingwheels, and on said driving-shaft are mounted power transmitting devices adapted to be thrown into and out of gear therewith, and transmit either propelling motion to the can riage of the engine, or power to machines remote from the engine. My invention consists, chiefly, in the combination, with the said driving-shaft, of a Windlass thrown into and out of gear with the said driving-shaft, so that said engine is capable of performing its various functions by the medium of one and the same driving'shaft.
