CAR=AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 3111717, dated February 3, 1885.

Application filed December 8, 1884.

To all whom it may concern: 7

Beitknown that I, SUMNER A. BEMIS, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Oar-Axle Boxes, of which the following is a specification.

This invention relates to improvements in the caps of car-axle boxes, and in the means for securing said caps to the box, the object being to so construct and secure the cap to the box as to avoid forming any projecting fastening parts on the front end of the box or cap, and to arrange the bolt by which the cap is secured entirely behind the exterior end surface of the cap and box, in order that there may be no danger of having the bolt or any projecting part of the cap struck and injured or displaced by a passing object.

In the drawings forming part of this specification. Figures 1 and 2 illustrate parts of the front end of an axle-box having thereon a cap, and means for fastening the same to the box, all constructed according to my invention. Fig. 3 is a front elevation of the cap.

In the drawings,A is the car-box, having a bolt-socket, 7!, formed therein at the junction of its front end and bottom. Fig. 1 is a vertical section of the front end of the cap and axlebox; and Fig. 2 is a section of the same on the line as m, Fig. 1. The boxAis also provided with an upwardly-turned lip, 12, extend ing across its end. The box-cap is of a width equal to the end of the box A, and is of a curved form, as shown in Fig. 1. The cap has its upper edge made of hook form at 0, to engage with the said lip I) on the box, and its lower end, n, overlaps the end of the box outside of the boltsocket h. A linger-socket, e, is formed beneath the outer surface of the cap, having an upper overhanging portion for the ends of the fingers to engage with for lifting the cap to place it on and take it off from the box, said overhanging part having its outer surface 011 a line with the curve of the cap. The cap D has formed on its inner side, near its lower edge, two bolt-head brackets, o 12, forming jointly a socket to receive the head as of the bolt w, but separated sufficiently to let the bolt pass between them. The brackets 12 may have their outer ends united, if de- (Xo model.)

sired; but such construction would render the manipulation of the cap and bolt more inconvenient than to have the brackets separated.

A bolt, to, having its head 00 engaged with said brackets 12 c on the interior of the cap, extends through the socket 71., below the un der side of the box A, and is provided with a nut, z. The box A and cap D are made of cast-iron in the usual way.

The manipulation of the cap D, in connection with the bolt w and box A, is as follows: Fig. 1 shows the cap secured on the box, as though the latter were in actual use on a car, the nut a being screwed firmly against the un- 6 5 der side of the box, thereby holding the upper hooked edge of the cap firmly upon the lip I) on the box, and drawing the lower end, a, of the cap against the end of the box, thus effectually closing the latter and showing no projections beyond the surfaceof thecap. To remove the cap, nut .e is turned off from bolt 20, and the latter is lifted up far enough to clear its head from the inclosure of the brackets o '0, and then by putting the fingers in the socket e the cap may be removed Without taking the bolt out of its socket h, and be re placed by similarly lifting the bolt; or, if preferred, the bolt may be left hanging on the cap and be removed with the latter, lifting up the cap until the bolt is drawn out of its socket.

If the bolt is made to extend somewhat below the nut z, the latter may be unscrewed far enough to permit of lifting the bolt to disengage its head from the brackets o without taking the nut off from the bolt. Thus by the improvements herein shown and described efficient means are provided for fastening and unfastening the cap of a car-box without removing any part of the fastening devices, 0 thereby avoiding the loss of any of said parts. The aforesaid socket between the brackets o, to receive the bolt-head, is made of proper form and dimension to prevent the bolt from turning when nut z is screwed on and off. If 9 5 desired, the finger-socket in the cap may be omitted and the cap be handled by grasping it by its edges.

Vhat I claim as my invention is-' 1. A car-axle box having a lip thereon for lot the engagement therewith of the upper edge of the cap, and havinga vertical bolt-socket at its front end, a bolt extending through said socket and projecting beneath the box, a cap having its upper edge engaging with the lip on the box, and means, substantially as described, on its innerside,whereby the head of said bolt is engaged with the cap, combined and operating substantially as set forth.

2. A car-axle box having a lip thereon for the engagement therewith of the upper edge of the cap, and having a vertical bolt-socket at its front end, a bolt extending through said socket and projecting below the box, a cap having its upper edge engaging with said lip on the box, and a finger-socket sunk in its outer surface and projecting from its inner 15 surface, and brackets with which the head of said bolt engages, combined and operating substantially as described.

3. In combination, the box A, bolt 10, and the cap D, having the brackets 22 v thereon, 20 substantially as set forth.
