AXLE-BOX.

SPECIFICATION forming part of Letters IPatent No. 466,622, dated January 5, 1892. Application filed April 4, 1891. Serial No. 387,622. (No model.) Patented in Germany April 10, 1890, No. 53,817, and in Austria- T0 aZZ whom it may concern;

Be it known that I, MAX ORENSTEIN, engineer, a subject of the King of Prussia, and a resident of the city of Berlin, Germany, have invented Improvements in Axle-Boxes, (patented in Germany April 10, 1890, No. 53,817, and in Austria-Hungary November 5, 1890, No. 24,125 and No. 45,263,) of which the following is a specification.

This invention is designed to connect the lower part of the axle-bearings with the upper part without the use of screws, wedges, or other parts which may be lost on the journey, and to simplify the device for effecting the connection so that the latter may be made by any unskilled workman.

In the accompanying drawings, Figure l is a part side elevation and part vertical section. Fig. 2 is partly a plan and partly a horizontal section. Figs. 3 ands are detailed views.

A is the upper part and B the lower part of the bearing. The former is fixed to the longitudinal beams of the wagon by means of screwbolts, which are passed through holes 0 0 in the lugs pp. The lower part is fixed to the upper by means of two bolts a, one end of which has a round head a, the other end being bent over to form a rectangular hook a. The bolt is surrounded by a spring f below the bolt-head a. The partsA B have slots 8' and s", which in the top part A extend to the lugs 19 19, thus connecting the hole 0 with the hole provided for the bolt-head ct, while in the other part B they run into the hole for the bolt a. (See Figs. 1 and 2.) The lower faces at n of the cheeks Z Z, which are around the slots 8, are oblique, as shown in Fig. 4., which is an enlarged part side elevation of the lower part of the hearing. The faces n n are provided with two notches at right angles to the slots 3, as shown in Fig. 3, which is a view of the cheeks Z Z, as seen below. The bolts a are introduced into the upper part A of the bearing, so that the hooks a are at right an- Hungary November 5, 1890, No. 24,125 and No. 45,263i

gles to the wheel-axle. (See Fig. 1.) The upper part A is then screwed to the longitudinal beam of the wagon, which at the same time prevents the extraction of the bolt a. The lower part B is then placed against the upper part A, and the hooks a are turned so that they are parallel to the wheel-axle. During this rotation the hooks a slide on the oblique faces n n and pull the bolts a downward against the resistance of the springs until they fall into the notches 7o, where they are kept by the said springs f. Fig. 3 shows the hook at in the latter position. If the bearings are to be examined, the bolts are returned into their former positionthat is, at right angles to the wheel-axle-in order to free the lower part B for removal. The upper faces of the hooks a," are well rounded off to facilitate the displacement of the hooks a upon the notchesk. (See Fig. 4.)

Having now described my invention, what I claim is- 1. In an axle-bearing, the combination, with the upper part A and the lower part B, of bolts a, having rectangular hooks a", adapted to hold said upper and lower parts together.

2. In an axle-bearing, the combination, with the upper and lower parts A and B and the bolts a, connecting the same, of a spring f surrounding said bolts, cheeks Z Z, having their lower faces at n oblique, and notches in said faces, substantially as and for the purpose specified.

3. In an axle-bearing, the combination, with the upper and lower parts A and B, of the bolts a, having rectangular hooks a, the upper faces of said hooks being rounded, sub stantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MAX ORENSTEIN.
