CAR MOVER Filed June 4, 1952 2 Sheets-Sheet 2 Patented Feb. 20, 1934 UNITED STATES PATENT OFFICE 3 Claims.

This invention appertains to a novel device for moving or shifting railway rolling stock by hand and more particularly to a car mover of the type embodying a fulcrumed rail engaging shoe, an operating lever, and a car wheel pushing lever operatively connected to the rail shoe and operating lever.

One of the primary objects of my present invention is the provision of a novel car mover embodying a new type of push lever, so constructed that the same will engage the car wheel upon the initial application of the mover to the rail and wheel, whereby upon the start of actuation of the operating lever, movement will be imparted to the wheel.

Another salient object of my invention is the provision of a car mover embodying a novel pushing lever so arranged as to extend entirely across and over the nose of the rail engaging shoe, so that upon the placing of the shoe on the rail the entire forward end of the pushing lever will engage the periphery of the wheel, whereby upon application of force to the operating lever the wheel will be readily moved through the action of a multiplied lever force.

A further object of my invention is the provision of novel means for mounting the fulcrum points of the car mover on the shoe, whereby the same will act efficiently to grip the rail so as to prevent slipping of the device when the same is in use.

A further object of my invention is the provision of means whereby the fulcrum points can be readily removed and replaced by new points, when the original points become worn.

A further object of my invention is the provision of novel means for mounting the operating lever on the rail engaging shoe and novel means for connecting the operating lever with the wheel pushing lever, whereby the desired and effective motion will be transmitted to the pushing lever for facilitating the moving of the car.

A still further object of my invention is to )rovide a car mover of the above character which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed on the market at 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.

Figure 2 is a fragmentary bottom plan view of the same, parts of the device being shown broken away and in section to illustrate the novel connection between the operating lever, shoe and wheel pushing lever.

Figure 3 is a longitudinal sectional view through my improved device taken on the line 3-3 of Figure 2 looking in the direction of the gaging shoe illustrating the novel pivot pin, 0;

the wheel pushing lever being shown removed.

Referring to the drawings in detail, wherein similar reference characters designate the corresponding parts throughout the several views,

the letter A generally indicates my improved device which comprises the rail engaging shoe 10, which can be formed from a suitable casting or the like and the same preferably embodies

parallel side bars

12 and 13 connected together at their forward ends by means of the nose 14. As shown, the shoe is of a substantially triangular shape in longitudinal section with the apex portion disposed lowermost to form a fulcrum for rocking engagement with the rail.

At this point I arrange my noved fulcrum points or cleats l5 and 16 which are detachably held in position so that the same can be renewed when worn. Each of the fulcrum points or cleats is of a diamond shape in cross section and the lower face of the shoe is preferably concave so as to fit over the ball of the rail. The cleats are disposed on opposite sides of the longitudinal center of the shoe and angle downwardly in opposite directions from the longitudinal center of the shoe. the shoe is provided with seats 17 for receiving the upper faces of the cleats and the cleats are held on their seats by a removable plate 18. The forward end of the plate 18 is provided with The lower face of a lip 19 for engaging over the inner face of the shoe, it being understood that the forward end of the plate is inserted through a transverse slot formed in said shoe. The plate extends rearwardly from the slot and is held detachably in place by means of a removable bolt 20. As shown, the plate is provided with transverse slots 21 through which protrude the lower faces of the cleats for engagement with the rail. Obviously, when one of the points of the cleats become worn, the cleats can be turned by loosening the bolt to bring a new point into active position. When all of the points have become worn, the cleats can be removed and sharpened or the cleats can be replaced by new cleats.

The extreme forward end of the shoe is bifurcated as at 22 to provide the forwardly extending pivot ears 23 which support the trans versely extending pivot pin 24. The pivot pin is preferably made integral with the ears and one side of the pivot pin 24 is flattened as at 25, for a purpose which will be later set forth.

The rear ends of the

arms

12 and 13 support the main pivot pin 26 which can be in the nature of a removable bolt. This pivot pin 26 slidably and pivotally supports the operating lever 27. The operating lever 2'7 is provided at a point intermediate its ends with a slot 23 which receives the said pivot pin or bolt 26. The forward end of the operating lever beyond the slot 28 is provided with a lift arm 29 having a socket 30 formed in its extreme front end. The rear end of the operating lever can be formed in any desired Way for the reception of a suitable manipulating handle (not shown).

Arranged forwardly of the operating lever 27 is the wheel pushing lever 31, which is of a novel construction and which forms an important part of the present invention. This pushing lever 31 embodies a top plate 32 and the depending centrally disposed longitudinally extending reinforcing rib 33. The rear end of the rib is provided with a downwardly extending leg 34 carrying the circular pivot ear 35, which is received within the socket 30 of the operating lever 27. A pivot pin 36 operatively connects the pivot car 35 with the walls of the socket. This pivot pin can be made in any preferred way and can be in the nature of a removable rivet, if so desired. The forward end of the top plate 32 of the pushing lever curves forwardly and downwardly as at 37 and constitutes the nose for engaging the periphery of the wheel and this curving extension overlies the front end of the shoe and is of such a character as to substantially engage the entire width of the periphery of a car wheel. The forward end of the rib 33 of the pushing lever is provided with an annular pivot lug 38. The annular pivot lug 38 is provided with a circular interior bearing portion 39 having the narrow neck entrance 40. The interior circular bearing 39 normally'rides on the bearing face 41 of the pivot pin 24. When the narrow or restricted neck entrance 40 is placed in alinement with the flat side'25 of the pivot pin 24, the pushing lever 31 can be placed in position on the shoe. This facilitates the assembling of the device. It is to be noted that the normal swinging movement of the pushing lever will not aline the narrow entrance 40 with the flat side of the pivot pin 24 and thus, accidental displacement of the pushing lever will be prevented.

From the foregoing description, it can be seen that I have provided a novel car mover in which the parts can be readily assembled and in which all likelihood of the shoe slipping on the rail is prevented and one in which the pushing lever will engage the wheel at the initial application of the device thereto.

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

1. A car mover comprising a rail engaging shoe, a pushing lever rockably connected at its forward endto the forward end of the shoe, said pushing lever embodying a top plate and a de pending longitudinally extending rib, a depending leg formed on the rear end of the rib, a stationary pivot pin connected to the rear end of the shoe, an operating lever slidably and pivotally mounted on the pivot pin, a socket formed in the forward end of the. operating lever receiving the lower end of the leg, and a pivot pin connecting the leg in the socket.

2. A car mover comprising a rail engaging shoe having its forward end bifurcated to provide a pair of forwardly extending ears, a pivot pin formed integral with the ears and bridging the same, a wheel pushing lever having a pivot lug formed on the forward end thereof provided with a bearing opening having a restricted entrance, one side of the pivot pin being flattened whereby the pivot lug can be associated with the pin when the sides of the restricted neck entrance of the opening alines with the flat side of the pin, an operating lever pivotally connected with the rear end of the shoe, and means pivotally connecting the operating lever and wheel pushing lever together, the restricted neck entrance of the opening being out of alinement with the flat side of thepin during normal swinging movement of the wheel pushing lever.

3. A car mover comprising a triangular shaped shoe in side elevation having a rail engaging fulcrum on its lower portion intermediate the ends thereof, a pushing lever rockably connected to the extreme forward end of the shoe and having'an arcuate extension overlying the forward end of the shoe and extending entirely across the same, an operating lever rockably connected with the rear end of the shoe, and means operatively connecting the operating lever with the pushing lever.
