PORTABLE CAR-WHEEL HOLDER.

SPECIFICATION forming part of Letters Patent No. 556,764, dated March 24., 1896.

Application filed November 21,1895. Serial No. 569,743. (No model.)

To @Z5 whom t may concern:

Re it known that I, DAVID L. MCMICKEN, a citizen of the United States of America, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Portable Car-Wheel Holder, of which the following is a specification.

It is matter of coininon occurrence in railroading, particularly when long and fast runs are made, that the supply of oil in the bearing-boxes becomes insuiiicient and the friction of the axle on the bearings produces a heat of such intensity as to ignite the Waste or oil in the bearing-boxes. This is commonly known as a hot box. When this occurs, the bearings are frequently damaged to such an extent that further use thereof will irrepara-bly injure the axle.

l'leretofore it has been customary to replace bearing-blocks thus damaged in the shops, Where means were convenient for .raising the ear.

My object is to provide a simple, strong, and dura-ble device of a size and shape that may be easily transported and cheap enough to be carried with every train and of such a size as to overlap two ties and thus provide a support for a jack when the axle to be raised is at any point relative to the ties, and adapted also to hold the adjacent car-Wheel to the track, and thus permit the removal of one or both of the bearing-blocks and at the same time not interfere with the use of the jack for all of the ordinary purposes to Which the jack is applied.

My invention consists in the construction of the device for the Vpurposes hereinafter set forth, pointed out in Iny claim, and illustrated lin the accompanying drawings, in Which- Figure l shows a side elevation of a part of a car on a track and the device in position supporting a lifting-jack and in engagement with a car-Wheel. Fig. 2 shows a sectional view of a portion of a car with my invention and a lifting-jack in position. Fig. S shows the device in perspective, and Fig. 4 is a transverse section of the saine.

Referring to the accompanying drawings, the reference-letter A is used to indicate the car-axle; A2, the Wheel fixed to the axle, having the usual outWardly-projecting flange B near its edge.

C indicates the boxing surroundin g the end portion of the axle, and C2 the bearing-blocks iitted to the axle within the boxing.

D indicates the ties; D2, the rail, and I? indicates a lifting-jack.

All of the above-described parts are of the ordinary construction. Hence a detailed description of each is omitted.

Il indicates a base of a size and shape designed to be placed on the ends of the railway-ties outside of the rails. It is of such a length that it Will firmly support a Weight at any position relative to the ties--that is, it Will overlap two or more ties. An arin .I is xed to its under surface and projects upwardly at its side and central portion, and at its upper end a hook .I2 is formed that projects outwardly from the base. This arm is of such a length that the hook on its end will engage the outer flange of a car-Wheel when the base is resting on the ties. As this length is the same on the greater portion of all raill Ways, it is unnecessary to make this arm adj ustable as to length.

K indicates a handle on the edge of the base opposite to the arm J.

III practical use the device is placed on the ends of the ties directly beneath the axlebearings to be removed, with the hook J 2 of the arm .I in engagement With the flange on the outer surface of the nearest car-Wheel. The lifting-jack is then placed on the base and in engagement with the boxing of the axle. As the jack is elevated, the Weight of the car is of course thrown upon the base II and the arm J iirinly holds the Wheel to the base, so that the boxing Inust be elevated relative to the axle, thus permitting theremoval of the Worn-out bearing-blocks and replacement by perfect ones.

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

A device for holding a car-Wheel to a rail and'for supporting a lifting-j acl: atany point relative to the railway-ties, comprising a fiat base of a length sufficient to overlap two ties, and an arm iixed toits central portion having a hook at its upper end to engage the flange of a car-Wheel, for the purposes stated.

DAVID L. MCMICKEN.
