sun-m Specification of Letters Patent.

Patented Jan. 16, 1917..

To all whom it may concern.-

Be it known that 1, CHARLES MOCARTER, a citizen of the United States, and a resident of Decatur, in the county of Macon and State of Illinois, have invented a new and Improved Car-Mover, of which the following is a full, clear, and exact description.

My invention relates to a contrivance whereby cars can be easily moved on the tracks, and the object thereof is to provide a simple, inexpensive and efficient device for the purpose stated.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

1n the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my invention as applied to a car wheel to move a car; Fig. 2 is an end elevation, the actuating lever being shown in section; Fig. 3 is a fragmentary rear elevation similar to that shown in Fig. 2 but illustrating the contrivance in the position when the operating lever is moved upward or when the device is disengaged from the car wheel; Fig. 4 is a top plan view; Fig. 5 is a side elevation of the upper part of the device from the side opposite to what is shown in Fig. 1; Fig. 6 is a perspective view of the cam; Fig. 7 is a perspective View of the wheel and clamp which carries the cam; Fig. 8 is an elevation of a modified structure of the wheel clamp; and Fig. 9 is an elevation of a further modification of the wheel clamp.

Referring to the drawings, 10 is the car riage truck or frame which has spaced flanged rollers 11 at the base for riding on a rail 12 of the track. The carriage frame 10 at the top thereof has a bearing 13 disposed transversely of the frame for accommodating a double crank shaft 14-, the two cranks 15 and 16 respectively being at the ends of the shaft and directed oppositely. The crank 16 has a socket for an end of an operating lever 17 whereby the shaft 14 may be rocked in the bearing.

A link 18 connects the lug 19 of a cam or jaw 20 to the crank 15. The jaw is mounted to revolve on a trunnion 21 provided at one end of a clamp 22. The clamp extends transversely of the frame and has at the other end a stationary jaw 23 whereat the clamp is suspended by a link 24 from a lug 26 extending from the crank 16. The link passes through a slot in the lug. The clamp 22 is bent at the jaw 20 to clear the flange of the car wheel 27. The frame 10 has a boss 28 constituting a guide for the clamp 22, the curvature of which is such as to maintain the clamp in close proximity to the car wheel when said clamp is moved by the rocking of the crank shaft 14:.

The clamp 22 is balanced on a link 29 which is suspended from one end of a lever 30 fulcrumed between its ends on a cap of the bearing 13. The link 2-1 has a collar 31 adapted to engage the lug 26 when the clamp 22 is moved upwardly by the lever 30 where by the upward movement of the fixed jaw is arrested, while the movable jaw is free to move; consequently the distance between the two jaws is increased and the device may be brought into engagement with the car wheel. In releasing the lever 30, gravity brings the clamp into engagement with the sides of the car wheel.

'Bymovingthe actuating lever 17 down, the grip of the clamp on the wheel is increased, and, consequently, the car wheel is caused to move by the downward displacement of the actuating lever. As the actuating lever 17 is moved upward, the hold of the clamp on the car wheel is released, due to the fact that the lug 26 is shorter than the crank 15, consequently, the distance between the fixed and movable jaws is increased during the initial upward move- 1116111 of the lever 17. A reverse initial movement of the lever 17 shortens the distance bet-ween the fixed and the movable jaw for the same reason and causes the clamp to grip the sides of the wheel.

It will be noted that the clamp 22 has lugs 32 and 33 which are engaged by the links 24 and 29 respectively. The clamp has 7 be operated from the crank and the other from the lug 26.

In Fig. 9 the clamp 22 is shown provided with twofixed jaws 23, the engagement of the wall with the said jaw being obtained by the unequal displacement of the two fixed jaws through the medium of the crank 15 and'the lug 26. It will be noted that the operating lever 17 is outside of the track,

consequently it may be operated without any hindrance where two cars are coupled, for there willbe plenty of room to move the lever due to the fact that said arm is outside of the track.

I claim:

1. A car mover comprising a frame, a lever fulcrumed onthe frame, a clamp for engaging the sides of a car wheel operable by the movement of the lever, and a boss extending from the frame for guiding the movement of the clamp.

2. A car mover comprising a frame, rollers therefor for riding on a rail, a double crank shaft mounted to rock in the frame, the two cranks being directed oppositely, one of said cranks having a socket, a lever engaging said socket whereby the shaft may be rocked, a lug extending from said socket having crank in a direction parallel to the second crank, said lug being shorter than said second crank, and a. clamp suspended from said lug and second crank to engage or disengage the sides of a car wheel when said shaft is rocked.

3. A car mover comprising a frame, rollers therefor for riding on a rail, a hearing at the top of the frame disposed transversely thereof, a double crank shaft in said bearing, the two cranks being disposed oppositely, one of said cranks having a socket, a lever engaging said socket, a lug extending from said crank having a socket in the same direction withthe second crank. said lug being of a shorter length than said second crank, a clamp for engaging the sides of a car wheel, links connecting said clamp to the lug and said second crank, and means for moving the clamp between the lug and the second crank.

. 4:. A car mover comprising a frame, rollers therefor for riding on a rail, a clamp for engaging the sides of a car wheel, a lever fulcrumed on the frame, and means for connecting the lever to the ends of the clamp so that one end of the clamp has a greater movement than the other during the movement of the lever, whereby said clamp may be caused to engage or disengage the car wheel.

5.
