JOHN J. SOHADT, OF ALLENTOWVN, PENNSYLVANIA.

AXLE- NUT.

SPECIFICATION forming part of Letters Patent No. 425,635, dated April 15, 1890.

Application filed December 14:, 1889. Serial No. 333,837. (No model.)

To all whom it may concern;

Be it known that 1, JOHN J. SCHADT, a'citizen of the United States, residing at Allentown, in the county of Lehigh, State of Pennsylvania, have invented certain new and use ful Improvements in AXle-Skeins, of which the following is a specification, reference'being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in axle-skeins; and it has for its object, among others, to provide forthe taking up of lost motion or play without the employment of the ordinary washers. It aims, also, at improvements in general in the construction of the skein and axle and the cap and their relation to each other.

Other objects and advantages-of the invention will hereinafter appear, and the novel features will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying"drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a longitudinal section through the axle-spindle, skein, or sleeve and screwcap. Fig. 2 is a'longitudinal section through the cap removed. Fig. 3 is a side view of the cap detached. Fig. at is an end view of the same. Fig. 5 is alongitudinal section through a portion of thcaxle spindle and sleeve or skein. Fig. 6 is an end view of Fig. 5. is an end view of the cap. Fig. 8 is an end view of the washer-ring.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the axle-spindle, and B the box or sleeve, the latter being formed with an interior shoulder a to engage the shoulder b on the spindle, as shown in Fig. 1. The outer ends of the sleeve and spindle terminate at the same point, being fiush at the end, as shown in Fig. 5. The outer end of the spindle is formed with a chamber 0, interiorly threaded, as shown, to receive the screw-threaded bolt E of the cap. The cap D is upon the exterior of the ordinary form, but upon the inner portion is formed with the integral screw-threaded bolt portion E, the threads of which are adapted to engage the interior threads of the chamber in the spindle. The cap is also formed Fig. 7

with an annular fiange or rim D, inclosing a chamber provided with two annular grooves F and G, the latter adapted to receive a washer-ring H, as shown in Fig. 1, and the other to receive the end of the spindle, the shoulder thus formed being designed to abut against the end of the spindle, the end of the sleeve abutting against the washer-ring, as shown in Fig. 1. The bolt port-ion E of the cap should normally be of somewhat less length than the depth of the chamber in the end of the spindle, as shown in Fig.1, so that as the parts become worn the bolt will not touch against the bottom of the chamber.

By ordinary constructions, as the axle box or sleeve, by friction against the axle-shoulder, shortens the former and produces play or lost motion, it is common to compensate for the same by means of leather washers. By my construction the face of the spindle is filed away as the sleeveor box becomes worn until it becomes even or fiush with the box, and thus removes the play or lost motion.

I deem it important that the cap D be formed with two annular grooves, as shown in Figs. 2 and 7, so that the spindle may have a bearing against one portion of the cap and the sleeve Z) bearing against the washer, so as to bring the end of the spindle and sleeve flush with each other, as shown in Figs. 1 and 5.

What I claim as new is The combination, with the spindle formed at its outer end with a chamber, of the sleeve around said spindle, a removable cap to said chamber formed with an integral bolt portion, and an annular flange with two annular grooves upon different planes parallel with the bolt portion within the space inclosed by said flange and one wider than the other and communicating with each other, and a washer held in the outermost of said grooves and bearing on the end of the sleeve, the outer end of the spindle and sleeve being fiush with each other, the latter bearing against the end wall or bottom of the deeper groove and the former against the end wall or bottom of the shallow or inner groove, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
