SPECIFICATION forming part of Letters Patent No. 780,211, dated January 17, 1905.

Application filed September 2, 1902. Serial No. 122,018.

To @ZZ whom it may concern/.-

Be it known that I, AUGUSTUS CAsNon MAS- sEY, of No. 132 Stimson Block, in the city of Los Angeles, inthe county of Los Angeles and State ot' California, have invented certain new and usefulq Improvements in Axles for Railway or other Vehicles, of which the following is a full, clear, and exact description or speciiication, reference being had to the annexed drawings, and to the letters marked thereon.

My invention has for its object to enable the wheels of vehicles used on railways and other roadways to be rolled upon a curved track without straining the axles torsionally, and besides constructing the axle in two portions, one fitting into the other at or about the center of the axle, as set forth in the specifications of my two previous Letters Patent, respectively having the numbers and dates as follows: 662,540, November 27, 1900, and 672,949, April 30, 1901. My invention otherwise consists in constructing each halt' of the axle at or near the center where the halves meet with a space between two flanges, one fiange being on each half of the axle and the space thus formed being' oi suilicient width and depth to receive between the ianges a loose ring whose outer diameter is equal to the diameter of the langes and whose interior diameter is larger than the diameter of that portion of the axle, which consists oi" a cylindrical projection extending from the flange of one half oliI the axle to the flange of the other halt' of the axle, so that an annular space is formed between the interior of the loose ring and the cylindrical projection on one-half of the axle. In this annular space antifriction` balls or rollers are carried, and the whole of these central parts, including the iianges, the loose ring, and the antit'rictionrollers, also the adjacent parts oi' the axles, are carried within'a yoke or box which holds the parts together, the entire construction or arrangement being such that the parts are held together antit'rictionally, so that they can yield rotatively on the occurrence of any torsional strain produced by any pair or' wheels and axle rolling upon a curved track of which the rail of one track is longer than the rail of the other track.

On the annexed drawings, Figure l is an elevation, partly in section, oi. a pair of wheels and a railway-car axle constructed in accordance with my present invention. Fig. 2 is an elevation of the central part or' the axle, showing the exterior etl the yoke or box containing and holding in operative relationship the yielding' parts thereof. Fig. 3 is a transverse section on the line a e, Fig. 1. Fig. 4c is a transverse section o-n the line Fig. 1.

1n the drawings each halt' oli the axle is marked A and A', respectively. On the half of the axle marked A there is formed the lflange B, and on the other hali` of the axle marked A there is formed the liange B'. Projecting from the center of the iange B is the cylindrical portion marked (l, Fig. l, which extends across the space between the flanges B and B', so that the outer end of the cylindrical portion C bears against the central portion ci the flange E, and the central part otl the axle A/ is formed with a conical nose D, projecting' from its iiange B into a corresponding conical recess in the cylindrical part C of that haltl of the axle marked A. As will be seen by reference to the drawings, an annular space is thus provided between the flanges B B, wherein the loose ring E is placed, and in the annular space thus formed between the interior or' the loose ring E and. the cylindrical projection C the antifriction balls or rollers F are contained. The whole of the central parts et' the axle thus constructed are held together by means elI the box or yoke G, which is constructed in two halves, as shown in the drawings, the halves constituting' the yoke being held together by bolts and nuts H.

1n putting the several parts or' this device together they are oiled or greased, so as to allow the saine to yield rotatively with a miniinuni friction on the arising et a torsional strain, and any oiling device may be applied to the yoke for passing oil as a lubricant to the interior parts whenever necessary, such lubricating device, however, forming no part ot' this invention..

I would have it understood that my invention includes such changes and modifications in the shape of the device and its parts as may i'all Within the terms and scope of the following claims.

Having now described the nature ot' my said invention and the best system, mode, or manner I am at present acquainted with for carrying the same into practical effect, I desire to observe in conclusion that what I consider to be novel and original and therefore claim as the invention to be secured to me by Letters Patent, is as follows:

l. The axle-joint wherein each half of the axle is constructed at or near its center with a iiange of larger diameter than the axle itself, one haltl of the axle having a cylindrical nose projecting' from its center toward the other half of the axle thus forming a space between the flanges, the other haltI of the axle having a nose projecting into a recess in the central cylindrical projection of the first-named halfaxle, the space between the fianges containing a ring Whose external diameter is the same as the external diameter of the flange, and having antifriction balls or rollers in the annular space formed between the interior of said ring and the cylindrical projection, the Whole being contained or held in operative relationship within the box or yoke, substantially7 as hereinbefore described.

2. The combination of the two half-axles, each half-axle having a flange at or near its inner end, the cylindrical central projection on one half-axle, the ring in the space between the flanges, the antifriction balls or rollers in the annular space formed by the interior of the ring and the exterior of the cylindrical projection, the conical nose and recess on each half-axle, respectively, the box or yoke and bolts for holding or containing the whole of the parts in operative relationship, substantially as hereinbei'ore described.

In testimony whereofl I have hereunto set my hand and seal, this 10th day of July, A. D. 1902, in the presence ot' two subscribing Witnesses.
