IMPROVEMENTIN ROLLING-SHOES FOR REPLACING CARS.

Specication forming part of Letters Patent No. 38,671, dated May V26, 1863; antedated.

, March 13, 1863.

To all whom it may concern Be it known that I, WASHINGTON L. GIL- RoY, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Rolling Shoe for replacing cars upon railroad-tracks and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the accompanying drawings. making a part ot' this specilieation, in Which- Figures l and 2 are 'side views; Fig. 3, an end view of the shoe applied to a car-wheel and Fig. 4, a plan view of the shoe-plate as its form appears before it is bent to receive its rolling base-like letters indicating the same parts when in the dierent figures.

The nature ot' my invention consists in providi ng a metallic shoe which will receivea portion of the flange of a car-wheel, and titting it with arolling support or base, substantially as hereinafter described, so that one of the s lid rolling shoes may be readily applied to each of the wheels to be moved and be operated so as to carry the car into its proper position over the track and drop it upon the rails as required, and at the same time also relieving itself from the wheels.

In the drawings, A is the shoe proper, B its rolling base, and C a section of a car-wheel resting in the shoe.

In constructing the part A, I take a plate of wrought-iron-say half an inch thick, more or lessand cut it into the form represented in Fig. 4, excepting the two rings d d, which are afterward riveted thereto. I then turn its under edge upward, on the dotted line a', so as to produce a trough, a2, Figs. l and 3, which will I'eceive or fit the Ilange c of a car-wheel when applied thereto, substantially as represented in Fig. 3, and then bend its two forked ends c d3 each to a right angle with the side which is opposite to the one having the trough a. Awrought-iron roller, B,provided with strong' journals b b', which are squared at their outer ends, is then fitted to rotate in the space left between the two ends a3 a3 of the piece A, and retained by fastening the two rings d d previously slipped onto the journals-to the forked ends ofthe same in any suitable manner, lthe squared ends of the journals b b', projecting so as to allow of the applicatlon and use of a ratchet-lever to rotate the roller.

'free from the wheels.

The drawings are about one-ifth of the full size of a working-shoe.

Operation: ln applying this rolling shoe to the purpose intended, the wheels which require to be replaced nponthe track are first' to bejacked up sufficiently to admit of the introduction of the lower part of their respective flanges c into the trough a2 ot' the shoes, the sides ot' the latter respectively resting against the flan ge sides of the wheels. Planks, or their equivalents, are next to be blocked up beneath the shoes so as to form a plane from each wheel on a line with the top of the rail which is to receive the wheel, the planks between the rails being short enough to allow the wheels thereon to drop from their ends upon the rail, as indicated at Wunder Fig. 3, while the planks for the wheels on the outer side of the track are each to be abutted against the outside edge ofthe rail, as indicated at Y, Fig. 5, so that the base, B, after rolling over the planks and across the rail, will drop the wheels in place upon the said rail, the shoes, in both cases, at the same time dropping down The hole e, near the upper edge ofthe shoe, is intended for the introduction of ones hand in carrying it. These shoes are comparatively small7 and can, therefore, be easily stowed and carried, and can quickly be applied to use under almost any emergency so as to be entirely eifeclive for the purpose.

I do not desire to confine myself in their manufacture to the precise manner in which the two parts A and B are constructed and seamed together as described and set forth, as these may be varied without altering the general result; but,

Having fully described the nature and pointed out the utility of my invention, and also shown what I believe to be the best mode of carrying it out into practice, what I claim as new, and desire to secure by Letters Patent, is

rIhe employmentof a portable shoe, combined with a rolling support or base, the same being constructed and applied to operate substantially as described and set forth, for the purpose specified.
