IMPROVEMENT IN RAILWAY CAR-WHEELS.

Specification forming part of Letters Patent No. 120,985, dated November 14, 1871.

To all whom it may concern:

Be it known that I, HENRY C. LocKwoon, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and valuable Improvement in Car-Wheels; and I do hereby declare th at the following is a full7 clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing .is a representation of a central vertical longitudinal section of my invention. Fig. 2 is a vertical cross-section of the same.

This invention has relation to car-wheels; and it consists in the novel construction and arrangement of an elastic rim or periphery, whereby the tendency of the wheel to rattle and jolt on the rail is lessened. A i

Referring to the accompanying drawing illustrating this invention, A represents a railroad car-wheel, around the periphery of which I sink a groove, A', having the iianges a a' on the sides, and place therein an India-rubber collar, B, of equal width, but in thickness less than the depth ofthe groove. I so form this groove that the outer face of the wheel flange a shall be nearly iush with the nearest side of the groove A', due allowance being made for the usual bevel of said For the rim or periphery' of the wheel A I provide a number of fellies, G, adapted in size to iit the groove A', outside the collar B, in such a manner that each, when pressed upon, will spring or give slightly with sufficient elasticity to overcome or compensate for the slight irregularities of the rails or other causes, of the' rattling or jolting of the car-wheels when the same are in motion. Through the fellies C I cut at each end a hole, and extend the same through the rubber cushion and into the body of the wh eel in a radial direction. In said hole I insert a screw, D, having a tapering head to fit the opening in the felly, and near its inner end a longitudinal key-slot, (i, adapted to receive a key, d1, employed for the purpose of securing the pin in place. rIhe holes d? and the slots cl are elongated sufficiently to allow the pins D all the required space for the change of posi tion resulting from the springing of the elastic fellies. E represents nuts which are placed over the inner ends of the screws D before the insertion of the keys. The nuts and keys are put in place through the apertures E', cut through the body of the wheels at the proper positions. These aperA tures are shaped so as to have a hat surface to let the Washers E rest against, as shown in the drawing. The fellies C constitute the rollin g periphery of the car-wheel, and hence are beveled and outwardly-formed, in accordance with the usual method of con struction. The bottom of the groove in which the cushion B rests may be flat, but I prefer making it raised to a ridgein the middle, as shown clearly in Fig. 2, and shaping the cushion to fit it. In this way there will be greater elasticity at the sides of the cushion than between them, which will allow the i'ellies a rocking motion, so as to conform more readily to the irregularities ofthe rail-surface.

I claim as my invention- The improved railroad car-Wheel, having the elastic packing B and separated fellies C arranged within the groove A', in connection with the movable screws D, keys D', and nuts E', or their equivalents, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
