CAR-AxLE Box. l

SPECIFQATION forming part of Letters Patent No. 315,581, dated April 14, 1885.

Y i Application filed February 6, 1855. (No model.)

To all whom it 'may concern,.-

Beit known that I, WILLIAM E. WILcox, of East Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Car-Axle Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to car-axle boxes; and it consists in the improved Vcombination of parts that will more fully hereinafter appear.

In the drawings, Figure l is a side view of a car-axle box embodying my invention. Fig. 2 is a longitudinal vertical sectional view of the car-axle box through the center of the axle. Fig. 3 is an interior view of the same, with the necessary parts removed to show the position of the rollers about the axle and the peripheral guide-fiange upon the inner side of the journal-box. Fig. 4 is the front cap of the box provided with antifrictional end bearing mechanism for the axle, with a portion cut away to show the anti-frictional mechanism of this portion of my invention. Fig. 5 is a detached plan View of one of the rings that provide the j ournal-bearings for the antifrictional rollers that, surround the axle and at the same time holds them in place. Fig. 6 is a detached view of vone of the anti-fric- -tional rollersthat surround the'axle, showing its construction.

In the drawings, A represents the `axle of an ordinary street-car; B, the anti-friction rollers placed within the axle-box D and surrounding the journal of the axle A, as shown in Figs. 2 and 3. The rollers B are provided with heads B at either end, and journals b. The length of the journals b should correspond to the thickness of the solid ring C, and their diameter to the size of the slots O inthe ring C, in which they turn.` The rollers B are also grooved, as shown at b', for the purpose of receiving the guide-ange D of box D, as shown in Fig. 2.

WILLIAM E. WILCOX, CLEVELAND, OHIO, ASSIGNOR `OF ONE-HALF TO opening, G2, of a size to accommodate theaxle upon which it is to be used. From this central opening are grooves or slots O', to receive the journals b of the rollers B. In each axlebox two of lthese rings are used, as shown in i Fig. 2, for supporting the rollers; The inner surface of the axle-box is provided with a i guide-flange, D', that runs in the grooves b of 5 5 the rollers, thereby preventing displacement of the rollers within the box.

My axle-box is also provided with an antii friction bearing for the'outer end of the axle. 6o

This consists of a plate, E, Fig. 2, against which the axle bears. This plate rests upon balls E', placed in a circular groove, E2, in the cap D2. The plateis held in place by the bolt e, that passes through the plate and the cap, and at the same time holding the balls E' in the groove E2. This portion of my invention is particularly valuable upon curves, i where the draft of the car is always largely increased, owing to the friction caused by the collar of the axle bearing against the axlebox. This bearing of the .collar of the axle is prevented by :my invention, the end of the axle bearing against the plate E, which turns on the balls E. l

What I claim is i In a car-axle box, the combination, with the anti-friction rollers B, provided with journals 1 i b and groove b', of the rings O and the antifrictional end bearing mechanism consisting of the plate E, balls E', and groove E2 in the cap D2, when constructed substantially as and for the purposes shown.

In testimony whereof I sign this specification, in the presence of two witnesses, this 28th day of January, 1885.

WILLIAM E. wILcoX.
