CAR MOVER Filed April 4, 1935 2 Sheets-Sheet 2 Patented May 5, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention appertains to a device for moving railroad rolling stock, and more particularly to an improved car-mover of the type illustrated in my prior Patent No. 1,902,658, issued to me March 21, 1933.

In my mentioned patent I disclosed an antifriction connection between the car wheel-enaging member or lever and the main operating lever. My present invention has for one of its primary objects the provision of means for improving said connection, whereby the mover will be easy to actuate, and great leverage will be obtained.

Another salient object of my invention is to provide an improved car mover in which the various parts will be easy to assemble, and one in which the main operating lever can be quickly connected to the fulcrum track-shoe, and to the wheel-engaging member.

A further object of my invention is to provide an improved track-mover of the above character, which will be durable and efilcient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a top plan view of my improved car-mover, with the operating handle removed, parts of the view being shown broken away and in section to illustrate structural details.

Figure 2 is a side elevation of the improved car-mover, showing the wheel-engaging lever in its elevated position, parts of the view being also shown broken away and in section.

Figure 3 is a view similar to Figure 2, showing the wheel-engaging lever in its lowered position.

Figure 4 is a detail transverse section through the car-mover taken substantially on the line 44 of Figure 2, looking in the direction of the arrows.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter M generally indicates my improved carmover, which comprises the rail-engaging shoe 5, the car wheel-engaging lever l5, and the main operating lever 25.

The rail-engaging shoe 5 can be formed from a suitable casting or the like, and the same preferably embodies parallel side bars 6 and 1 connected together at their forward ends by means of a nose 8. As shown, the shoe 5 is of a substantially triangular shape in side elevation, with the apex portion disposed lowermost to form a fulcrum for rocking engagement with the track rail. Suitable cleats or spurs 9 can be utilized for engaging the rail, and the same can be of the character shown in the prior patent to Fred J. Miller, No. 1,948,123, granted February 20, 1934.

The extreme forward end of the shoe 5 can be provided with the transversely extending pivot pin Ill for rockably supporting the rail-engaging lever l5, as will be later set forth. The pivot pin is preferably made integral with the side walls 6 and I of the shoe, and one side of the same is flattened, as at I I. The rear ends of the parallel walls 6 and 'l are provided with bearings l2 for the reception of a transversely extending removable pivot bolt l3, employed for rockably connecting the main operating lever 25 with the rail-engaging shoe 5. The wheel-engaging lever l5 includes a top plate l6 and a depending, centrally disposed, longitudinally extending reinforced rib [1.

The forward end of the plate l6 and the rib I! is provided with a transversely extending annular bearing l8 having a restricted neck entrance l9. By this arrangement the wheel-pushing lever l5 can be readily connected with the pivot bolt I0 when the neck entrance I9 engages the narrow side of the pivot pin l0.

Formed on the. extreme end of the plate l6 and the rib I! are depending spaced parallel ears 20. These cars 20 extend at an angle to the plate l6, and are preferably connected at their lower ends by a cross-bar 2|. At a point spaced from the cross-bar 2i is a transversely extending pivot pin 22, having its ends anchored in the ears 20. This pin 22 rotatably supports the anti-friction roller 23, the purpose of which will be later set forth.

The main operating handle 25 includes a socket 26 for receiving the operating handle (not shown). The. lever 25 forwardly of the socket 26 carries the forwardly projecting nose 21, which is inserted between the ears 2!] and under the antifriction roller 23. Directly forward of the socket 26, the main lever 25 is provided with a bearing 28 for receiving the pivot bolt 13, and the lever 25 is freely rockable on this bolt. By referring to Figures 2 and 3, it can be seen that the upper face of the nose 2'! is of a slightly arcuate form to provide the roller-engaging lift track.

Obviously, when the car-mover is in use and downward pressure is exerted on the outer end of the main operating lever 25, the wheel-engaging push lever will be forced upwardly, and the roller 23 will travel along the nose 21 of the main operating lever. This gives the desired leverage and insures the easy manipulation of the mover.

Great stress is laid on the simplicity of the device, and the mover can be easily and quickly assembled. After the wheel lift lever l5 has been placed in position on the track-shoe, it is merely necessary to insert the nose 2'! of the main lever between the ears 20 of the wheel lever under the roller 23, and to then place the pivot bolt [3 in position.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

l. A car mover comprising a shoe having a rail-engaging fulcrum on its lower face intermediate the ends thereof, a car wheel pushing lever rockably connected to the extreme forward end of the shoe, depending spaced parallel ears formed on the rear end of the car pushing lever,

a rotatable roller mounted between said ears, a main operating lever having a forwardly projecting nose detaohably received between said ears and under said roller, and a removable pivot connecting the main operating lever intermediate its ends on the rear end of the shoe.

2. A car mover comprising a shoe including a pair of spaced side plates, a pivot pin connecting the forward ends of said plates together, a railengaging fulcrum carried by the lower edges of said plates intermediate the ends thereof, a car Wheel pushing lever rockably mounted at its forward end on the pivot pin having a pair of depending spaced parallel ears on its rear end received between the side plates, a roller rotatably mounted between the ears, a main operating lever having a, forwardly projecting nose detachably received between the ears, said nose having an arcuate upper face for engaging the roller, and a removable pivot connecting the main operating lever intermediate its ends on the rear end of the shoe.
