UNITED STATES PATENT OF ICE,

ALFRED MAYER, OF PHILIPSBURG, PENNSYLVANIA.

CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 439,670, dated. November 4, 1890. Application filed May 26, 1890. Serial No. 353,175. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED MAYER, a citizen of the United States, residing at Phillips burg, in the county of Centre and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Wheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved axlebox for car or truck wheels, and has for its object to provide a device of the character described that shall be cheap, simple, and durable in construction, one in which the parts are easily assembled, and one that when properly arranged and oiled requires very little attention.

With these objects in View my invention consists in the peculiar construction of parts and their novel combination or arrangement, such as shown in the accompanying drawings, and more fully explained hereinafter.

In the drawings forming apart of this specification, Figure lis a perspective view of a wheel provided with my improved box. Fig. 2 is a Vertical longitudinal section of the box. Fig. 3 is a view showing the several parts detached.

In carrying out my invention I employ a hub-section A of iron or other suitable materiahwhich is provided with abore a, the surface of which bore is provided with two grooves a, which start from a common point near the forward end of the bore and pass spirally to the rear end, where they end in a common point.

Upon the exterior of the hub section, near its rear end, is formed an annular flange B, the forward face of which is perpendicular with the axis of the bore. A lug O is arranged a short distance forward of the flange and provided with a perpendicular rear face and an inclined forward face, the purpose of which will appear farther on. The forward end of the hub-section is reduced at a and around said reduced portion is placed the packing-ring D.

E indicates loops arranged upon the exterior of the hub-section about midway its ends, transverse to its longitudinal axis, and beneath said loop is placed a fiat spring F, said spring having perforations f near its opposite ends. One of the perforations fits over the lug C, the end of the spring bearing against flange B, and the opposite end of the spring projects beyond the forward shoulder of the hub. Directly beneath the spring the hub is recessed, as at c.

G indicates a cap provided with a central opening g, the edges of said opening being pressed inwardly, as shown, forming ateat g. The rear edges of the cap are provided at diametrically-opposite points with the rearwardly-projecting spring-catches H. Said catches being adapted to enter the recess a and engage the forward perforation of the spring F. The peculiar shape of the cap provides a reservoir for the oil, which is fed in through the aperture g, and by means of the spiral grooves the oil is carried to the rear of the box by one groove and to the forward end by means of the other groove, so that there is always a circulation of oil, no matter which way the wheel revolves. The packing-ringD prevents the escape of oil.

The operation and advantages of my improvement are obvious to every one skilled in the art to which it pertains.

Having thus described my invention, what I claim is- 1. In an axle-box, the combination, with a hub-section, of a cap-piece provided with catches adapted to be engaged by springs on the hub-section, substantially as set forth.

2. In an axle-box, the combination, with a hub-section provided with interior grooves, and with exterior leaf-springs, of a cap provided with a perforated teat and with catches adapted to be engaged by the springs on the hub, substantially as and for the purpose set forth.

3. In an axle-box, the combination, with a hub-section, of leaf-springs secured thereto and perforated at their forward ends, the cap-section constructed as described, and the spring-catches adapted to engage the perfo- In testimony whereof Iaffix my signature in 10 rations in the springs, substantially as depresence of two Witnesses. scribed.
