SPECIFICATION forming part of Letters Patent No. 703,906, dated July 1, 1902.

Application filed February 4, 1902. Serial No."92,568. (No model.)

To all whom it may concern.-

Be it known that I, ALONZO DrFAULKNER, a citizen of the United States, residingat Meyersdale, in the county of Somerset and State of Pennsylvania, have invented new and useful Improvements in Railway-Oar Chocks, of which the following is a specification.

This invention relates to railway-car chocks, and has for its object to provide a cheap, durable, and efficient device of the character described which may be readily applied to a track for chocking the wheels of the car at any point thereon.

A further object is to provide a device which is portable and may be used on rails of varyingdegrees of thickness.

The device is intended to be used at any prevent its moving in one direction. It is intended to employ the device particularly with cars where a grade is provided and where the brakes fail to hold the car, particularly when loaded, in an effectual manner.

Further advantages, as well as the peculiar construction of the device and the manner of using the same, will appear as the nature of the invention is better understood. r

In the drawings, Figure 1 is a perspective view of the device ready to be applied. Fig. 2 is a side elevation of a rail, showing the in-' vention applied thereto, and Fig. 3 is a'sectional view on the line 3 3 of-Fig. 2.

The reference-numeral 1 designates a block provided with a segmental curved end 2, formed to correspond with the contour of the car-wheel, which is adapted to rest against said curved portion snugly. The entire edge of the block is preferably bound by a strip of metal 3, which may be replaced from time to time as it becomes worn. On either side of the block and near the curved end thereof are countersunk vertically-arranged parallel plates or jaws 4, which project a slight dis; tance below the base of the block, so as to overlap the sides of the rail, as shown in Fig. 2. Near the rear endof the block are two similar plates or jaws 5 and 6, which are loosely secured thereto by a bolt 7, so that the lower ends of the jaws are expansible and retracti ble to accommodate the device to rails of varying widths. Abifurcated lever Sis secured to the block and preferably to the sides of the plates 4,and this lever straddles the block, so that by lowering the end'9 thereof the bifurcated portions will bear against the plates or jaws 5 and 6 and cause them to firmly im- ;pinge against the sides of the rail, thereby forming a lock .to retain the device rigid with relation to the rail.

In Figs. 2 and 3 the chock is illustrated as being applied to the smallestform of rail, and therefore the lever is illustrated as being on a horizontal plane. However, if the device is applied to a rail of greater width the lever will assume a position less than a right angle to that of a rail, according to the width thereof. In actualpracticeit hasbeen found that the weight of the lever is sufficient to securely lock the device through the medium of the jaws rigid with relation to the rail, and by moving the device at any predetermined point the car may be effectually chocked and any tendency to slide down the grade, owing toineffectual brakes or other causes, will be obviated.

It will thus be apparent that I have provided a cheap, durable, and efficient carchock which may be readily applied to and detached from the rail at any convenient point without the useof tools or implements of any'kind, and while I have specifically described the exact details of construction of the preferred form of this device Iwould have it understood that I reserve the'right to make such slight changes and alterations-as might suggest themselves from time to time without departing from the spirit of this invention.

Having thus fully described my invention, .WhEtlJI claim, and desire to secure by Letters Patent, is-

1. A car-chock having two pairs of jaws, one pair being'rigid, and the other pair expansible and retractible, and means straddling the last-named jaws anddesignedto force them against the sides of therails.

2. A car-chock comprising a rigid. pair of jaws and an expansible'and retractible. pair of jaws, and a bifurcatedlever designed to straddle the last-named pair of jaws and force them against the sides of a rail.

3. A car-chock comprising a body, a pair of plates carried thereby and having depending ends designed to overlap the tread of a rail, plates secured to the other end of the body and loosely mounted thereon to form expansible and retractible jaws, and means for forcing said plates against the sides of the rail whereby the body will be rigidly secured thereto.

4. A car-chock comprising a body, a pair of vertically-arranged plates carried thereby and having depending ends adapted to overlap the tread of a rail, a pair of vertically-ar-
