CAR-PUSHER.

SPECIFICATION forming part of Letters Patent No. 449,632, dated March 31, 1891.

Application filed August 7, 1890. Serial No- 361,370. (No model.)

To whom it may concern:

Be it known that I, JOHN M. JONES, a citizen of the United States of America, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a certain new and useful Oar-Pusher; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it ap- IO pertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to the class of car- 5 pushers which in their operation push against one end of the car and grip the track in such a manner as to automatically engage and disengage therefrom at the will of the operator.

The object of the invention is to improve the construction and to make them more useful and durable; and to that end it consists of several novel features that are illustrated in the accompanying drawings, and that will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation of the device, showing it attached to a rail and the end of a car. Fig. 2 is an end view of the rail, showing the clutch attachedto the carpusher that grips said rail. Fig. 3 is a hori- 0 zontal section on the line a: 90, Fig. 2. Fig. L is a side view of the forward end of the lever, showing its construction. Fig. 5 is a top view of the lever, further showing its construction and the means for the attachment of the link 3 5 that assists in removing the device from the end of the car. Fig. 6 is a plan, partly in section, showing the cuff and knuckle-joint.

In the figures like reference-marks indicate corresponding parts in the several views.

A is the end of a railway-car, and B the track. The lever O is universally hinged to the bracket D by the link E and pins e and c. The bracket D is attached to the car by the spike F, that is hinged to the bracket D by 5 the pin f. Pivoted to the lever in any suitable way is the link G, the functions of which will be hereinafter explained. The arm II, extending from the lever O to the rail, is hinged to said lever by the pin 71, and together til with it forms a toggle. On the bottom end of the arm H. is the bifurcated plate I, preferably fianged and forming three sides of a mat angle, as shown in Fig. 3, to combine lightness with strength, and to which are attached by bolts or otherwise the plates .I, having beveled inner edges, as shown in Fig. 3, to prevent them from slipping on the rail when in the position shown in Fig. 2, which figure is a back view of the lower portion of the arm II, as shown in Fig. 1.

The lever O is composed of three parts or membersnamely, the handle 0, the central part 0 to which is hinged the arm II, and the part K, by which it is hinged to the link E. The part c is pivotally attached to the part c, as shown, by means of a link 0 let into a slot in the end of each part, and the sleeve or coupling c' is slipped over the joint to prevent bending thereof under strain. By reason of this construction the parts 0 may be, by slip- 7o ping the said collar off of the joint, bent at an angle to the part- 0*, and the space required to operate the lever be thereby much lessened. The part K is attached by the bolt 7." and has a flange 7o, that acts as a brace, as shown in Fig. at, the said flange being inserted in a diagonally-extending groove in the end of the lever and by means of which the part K is greatly strengthened without materially weakening the adjacent part.

To operate this device it is attached to a car by driving the spike F into the wood-work, as shown in Fig. 1, and by placing the lower end of the arm H on the track, as shown in Figs. 1 and 2. The angle of the two elements of the toggle-lever thus formed may be governed at pleasure to the full limit of the length of the chain L, which prevents the raising of the lever O to so high a point as to permit the arm H assuming a position so nearly vertical as to prevent the required amount of increased power due to the action of said toggles. The universally-hinged joint between the lever and the bracket D permits the lever C to be carried to the outside of the car adjacent to the one that is to be pushed, or the device may be worked between the cars by shortening the lever, as hereinbefore specified. It is obvious that the angle to each other of the twg arms forming the toggle-lever maybe govce erned at will and that the shortened length of the hand'lever may be in that manner compensated for, or that a heavier ear maybe moved at the expense of speed.

To detach the device from the car, it is only necessary to place the free end of the link G over the upward projection f on the hinged spike 1*, raising the lever U to so do, which will, by means of the chain L, raise the arm II from contact with the track, after which a downward pressure of the lever (I will pull out the hook F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a car-mover, the combination of the lever G, arm II, block 1'), pivoted to said lever G, and bracket K, having the flange 7.; for the purpose of bracing said bracket K and preventing the same from turning in its place. substantially as shown and described.

Ina 0ai-l1iOVO1',1l1O combination of the block 1), the spike 1 hinged to the said block, the lever C, connected with the block I) by the link E, the said lever consisting of the parts a, c", and K, the parts 0 and 0 being, hinged together and the cuff a covering said parts at their connecting ends and the part K being connected to the part c' by the pin 70, the link G, secured to the part c", the arm II, the bifurcated plate I, and the plates J, secured to the arms of the said bifurcated plate, substantially as specified.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

JOHN M. JONES.
