BOX.

SPECIFICATION forming part of Letters Patent No. 549,926, dated November 19, 1895.

Application filedMarch 14, 1895.

- axle-spindle to prevent overheating, and, furv thermore,to provide means for preventing ingress of dust.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims. A

In the drawings, Figure l is a longitudinal section of an axle-box constructed in accordance with my invention. Fig. 2 is a transverse section through the lubricating-chamber. Fig. 3 is a detail longitudinal section with the spindle omitted.

Similar numerals of reference indicate corresponding parts in all the gures of the drawings.

1 designates the tubular body portion of the box, and 2 an enlarged portion communicating with said tubular portion and forming a lubricating-chamber, which is closed at the inner end by an abrupt wall 3, having an opening 4, which corresponds in diameter with the bore of the body portion of the box. The enlarged portion of the box is extended beyond said wall to form a dust-guard or flange 6, within which fits the collar 7 of the axle-spindle 8, said collar bearing against the inner surface of the wall 3. Extending from the outer surface of the wall to the outer end of the lubricating-chamber is a web 9, the edge of which is approximately iush with the surface of the bore of the box, said web serving to strengthen the enlarged portion of the box and also as a conveyer for the lubricating material to feed the same to the surface of the axle-spindle. One or more webs 9 may be employed, two bein'g shown in the drawings. The box is also provided with an exterior ear or wing 10, whereby it may be Serial No. 541,766. or@ model.)

secured firmly in the hub ofv a wheel. The collar of the axle-spindle is provided with a circumferential groove 1l to serve as a dustreceptacle or stop, and a washer l2 is interposed between said collar and the inner surface of the wall 3. A similar washer is arranged between the outer end of the box and the cap-nut 13, which is provided witha flange 14 to overlap the outer extremity of the box, and thereby exclude dust at that point. The spindle is provided with ak longitudinal oilconducting groove of the usual construction.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, I claiml. An axle-box provided with an enlarged portion forming a lubricating chamber in communication with its bore and closed at its inner end by a wall beyond which the enlarged portion of the box extends to form a dust-guard or ange, and a longitudinally disposed web connecting the wall with the shoulder between the enlarged and body-portions of the box, and serving to strengthen said enlarged portion and convey lubricating material to the surface of an axle-spindle, substantially as specified.

' 2. The combination with an axle-spindle having a collar provided with a circumferential groove, of a box having a bore to receive said spindle, an enlarged portion forming a lubricating chamber and terminated at its inner end by a wall having an opening in registration with the bore of the body-portion of the axle-box, a dust-guard or flange to receive the collar of the axle, and a longitudinally disposed web arranged in the lubricating chamber and projecting approximately to the surface of the spindle, substantially as specified. .y

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
