UNITED STATES PATENT OFFICEQ JOHN PENNYOOOK, OF MILWAUKEE, WISCONSIN.

,CAR-PUSHER.

SPECIFICATION forming part of Letters Patent No. 250,168, dated November 29, 1881,

Application filed September 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN PENNYOOOK, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Oar-Pushers, of which the following is a specification.

The object of my invention is a machine for pushing railroad and other cars from one position to another. by means of a powerful mechanism, giving a steady and regular motion in a forward direction along a track or upon a level surface, which will be more fully illustrated by referring to the accompanying drawings, in which Figure 1 is a sectional elevation. Fig. 2 is a cross-section through S H. Fig. 3 gives a full view (side elevation.) Fig. 4 is a back elevation of S H.

Similar letters refer to the similar parts throughout the several views.

In Fig.1, as above stated, the car-pusher is represented in a sectional elevation, the stem D embracing the top part, O, cont-aining the bevel-gears b c, and the lower part, E, containing the endless Worm S and the combined worm-gear and friction-wheel H. The base part E is a casing with an oblong opening, with sides projecting out to form the bearings for the pin n. Upon the inner side of said opening are located the endless worm S and the combined worm and friction wheel H. Said wheel H is peculiarly constructed, having a worm-gear, r, on its inner surface, with two flanges,pp, extending out from the center and upon each side of the worm-gear, forming aV. Upon the inner side ofthe flanges 191) are cast projection-strips at equal distance apart, and so placed that the strips on the one side of flange will come between the,corresponding strips on the opposite flange. For the purpose of taking a firm hold of the rail R, as shown in Fig. 4, to prevent the car-pusher from slipping backward, similar projections are on the outer edges of-said flanges p p, and for the same purpose when the machine is used upon a wooden floor or level surface. The wheel H revolves loose upon the pin ff and gears to the oonvolutions of an endless worm, S, on the lower part of rod d, the rod (1 projecting from the top part, 0, straight down through the stem D, resting on the shoulder K, and terminating in bearing an at the bottom end, F, arranged for that purpose. The driving-shaft ffrestsin bearings 0 0 upon each side of the upper chamber, 0. Upon the end of shaft f is the handle a, properly fastened. On the same shaftff, and inside of the chamber 0, is a bevel-gear, b, firmly secured. The bevel gear I) communicates with the bevel-gear c, which is firmly secured to the top end of shaft (1, as illustrated in the drawings. The cover 2 is for the purpose of incasing the bevel-gears b c and formiu g a bearing for the shaft f f.

the endless worm S, worm-gear and frictionwheel H upon a level plain, t.

Fig. 3 is an end view of the worm S, worm and friction wheel H resting upon the rail B.

Fig. 4 shows the car-pusher in full view. On the top end is an angle-projection, A, bearing against the car, with extension-bar B, upper chamber, 0, stem D, lower casing, E, foot-rest e, and combined Worm and friction Wheel H, resting upon the rail R, between the flan ges p p.

The operation of the carpusher will be fully understood in the illustration at Fig. 1., which represents a sectional view of my invention, showing all the interior arrangements, as before explained. Fig. 4 shows the car-pusher in working position, with the angle-projection A against the 'end of car and the frictionwheel H resting on the rail R, between the flanges pp. By turning the handle a on the drivingshaft ff, as shown in Fig. 1, motion is communicated through the bevel-gears I) 0 to the rod d, extending down through D to an endless worm, S, gearing into the worm-gear, giving a steady forward rotating motion to the friction-wheel H, resting on the rail R, which pressure moves the car-pusher and car in a forward direction.

Having thus described my invention fully in the foregoing specification, I claim as new and desire to secure by Letters Patent of the United States- 1. Acombined worm-gearandfriction-wheel, H, with their relative projections on the inner sides and outer flanges, p p, as shown and described, for the purpose set forth.

2. The rod d, guided in its upper part at w Fig.2 represents a sectional elevation through ICO and fastened in the lower part between the combinationwith the other parts, so constructcollars K K, and having an endless worm, S, ed,l0cated,and operated as and for the purpose 10 011 the lower part, and so arranged that the shown and described. convolutions ear with the worm-gear in the 5 friction-wheel H, substantially as described, JOHN PENNYCOOK' for the purpose set forth.

3. The stem D, with upper casing, 0, lower ALEX; CHRISTIE, chamber, E, neck 13, and angle-bearing A, in CHAS. W. BLUM.
