Application filed February 18, 1914. Serial No. 819,524.

To all whom it may concern:

Be it known that 1, JOHN CLIFTON TILLY, a citizen of the United States, residing at Rome, in the county of Floyd and State of Georgia, have invented certain new and use ful Improvements in Car-Wheel'Clamps, of which the following is a specification.

My invention relates to car wheel clamps.

The primary object of my invention is to provide an improved means for holding.

a car wheel on the rail while the journal box is being jacked in order to replace the brasses therein.

Another object of my invention is to provide a clamp composed of two members for frictional engagement with each other for facilitating the securement of the car wheel.

A further object of my invention'is to provide a device,.simple in construction, eflicient in operation, and one that can be manufactured and placed upon the market at a minimum cost.

Other objects, as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims.

In the drawings: Figure 1, is a view partly in section and partly in elevation of my invention applied to a car wheel. Fig. 2, is aperspective View of my invention.

Referring more particularly to the drawings in which similar reference numerals designate the corresponding parts throughout the different views the numeral 1 represents a rail on which is disposed a car wheel 2 carried by the axle 3, the latter belng ournaled in the box 1 which is supported by a jack 5 when it is desired to remove the brasses from the box. In order to prevent the wheel rising with the raising of the box I have secured to the rail 1 and the wheel 2 my improved clamp 6. The clamp 6 in this instance consists of a shank 7 formed preferably from a piece of rod iron which is bent at right angles to the body portion thereof to form a rigid jaw 8, the latter be ing bent adjacent the outer end thereof and have their engaging surfaces 10 and 15 arranged in convergent relation with each other with respect to the shank 7, this arrangement providing an efficient clamping means, as is obvious. V

The shank 7 is flattened as at 11 and has slidably mounted thereon a movable .j aw 12, the latter being formed from the same kind of material as the shank and has the inner end thereof enlarged and flattened and provided with an oval-shaped opening 18 for frictional engagement with the flattened portion of the shank. The. outer end of the jaw 12 is bent at substantial right angles and flattened to provide an engaging lip 14, the outer edge of which is cut diagonally outward and serrated to form teeth 15 so that the same will conform to and grip the tread of the wheel as is clearly shown in Fig. 1.

It is to be understood that the opening 13 is somewhat larger in diameter than the shank so as to allow the jaw 12 to slide on the shank and friotionally engage the same due to the weight disposed on the oppositely arranged engaging lips 9 and 14 and it will be seen that by increasing the weight or Patented May a, 1191s.

pull on the lips, the firmer the jaw will engage the shank.

The operation of my device is as follows: When it becomes necessary to remove the brasses (not shown) from the box 4 a jack 5 is placed under the box. It will be remembered that the equalizing bars of the truck restin the saddle in the top of the box and by raising the box the car supporting structure of the truck is lifted from the axle 3. If the wheel is not restrained, the same with the axle would lift with the box and it would be very difficult to insert the new brasses. To prevent this, my improved clamp is placed in a position as shown in Fig; 1 of the drawing. The lip 9 on the rigid jaw is placed on the underside of the head of the rail and the sliding jaw 12 is slid upon the shank 7 until it engages the tread of the wheel and the weight or pull caused by the raising of the box, on the oppositely arranged engaging lips causes the sliding jaw 12 to frictionally engage the shank and thus firmly hold the Wheel in position on the track without the employment of separate fastening devices for holding the clamp.

It will be obvious to those skilled in the art to which this invention relates that modifications may be made in detail without departing from the spirit or scope of the invention. T 7

Having thus described my invention what I claim and desire to secure by Letters Pat ent is: I

1. A car wheel clamp including a shank, an elongated rigid jaw extending from one end of the shank, an engaging lip on the free end of the jaw, another elongated jaw slidably but non-rotatably mounted on the shank, an engaging lip on the free end of the sliding jaw, the outer edges of the engaging lips being arranged in convergent relation with each other with respect to the shank and serrated for facilitating engagement with the under surface of the tread of a rail and the inner periphery of a car wheel for preventing movement of the wheel on the rail;

2. Acar Wheel clamp comprising a shank formed from rod metal having the upper surface thereof flattened, an elongated rigid jaw formed integral with the opposite ter- U minal of said shank and extending at right angles therefrom, an engaging lip formed integral with the free terminal of the rigid jaw and extending at approximately a right angle from the jaw toward the free end of the shank and in spaced parallel relation therewith, an elongated sliding jaw, the inner end of said sliding jaw being provided with a substantially oblong opening for frictional engagement with the flattened portion of the shank, a lip formed integral with. the free terminal of the sliding jaw and extending at substantially right angles therefrom in a direction toward the lip on the rigid jaw, and the free edges of the lips being cut diagonally and arranged in convergent relation with each other with respect'to the shank and also provided with serrations for engagement with the under surface of the tread of a rail and the inner periphery of a car wheel for preventing the movement of the wheel on the rail.

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