ving is a specification.

The improved axle-box for locomotive and other axles differs from others by'the use of three bushes or brass cushions instead of one, which bushes are made movable on the surfaces of their contact with the interior of the axle-box, being retained therein by flanges or projections, which prevent any motion of the bush along the axle, but allow the bushes to follow any displacement of the axle, so as to keep the whole rubbing surface in contact with the axle. This contact is maintained by a special construction of the axle-box, which maybe made of several pieces or provided with wedges or keys adapted to tighten the bushes, so as to take up the wear. It is advisable, in order to minimize the sliding re sistance of the contact-surface of the upper bush with the box, to provide special means of lubricating these surfaces from the upper oilreeeptacle of the box.

In further describing this invention reference will be made to the accompanying drawings, of which Figure 1 is half front view and half cross-section, Fig. 2 a vertical axial sec a horizontal section, of an axle-box embodying our invention, while Figs. 4 to 7 represent modifications.

The construction of Figs. 1 to 3 is easily applicable to the majority of existing locomotiveengines.

The body of the box is composed of three parts, and thelateral cheeks A are, or at least one of them is, made movable, so as to enable their being placed nearer to each other. In this arrangement the wedge B is sufficient to regulate the play of the box inside and outside. The bush is placed over the journal of the axle, under the block D, which takes up the load and serves as an oil-receptacle.

lateral flanges only, and in the same way the bush 0 issecured to the block I). The latter may, however, be rigidly connected or form one piece with the bush 0, if the block D is adapted to slide between the cheeks A. In this case the guide-pins would slide in slots of the cheeks and serve as guides.

The various movable parts described above have to resist the load of the engine and heavy strains, and are therefore made of phosphorbronze. In the arrangement illustrated the key B is sutlicient to take up the wear and to adjust the play of the box. In certain casesfor instance, where it is desired to make the body of the axle-box ofone piecethe lateral bushes may be made to approach each other by a key placed entirely inside the box and attached to one of the bushes.

Figs. 4 and illustrate the application of our invention to axle-boxes without wedgekey, and where one is obliged to add a movable wedge-shaped check having its outer face in contact with one of the guides, while its inner face is inclined and in contact with the Fig. 7 is a cross-section of an axle-box with a movable cheek and an outer adjusting-key. This modification allows of the utilization of old axle-boxes by removing one of the checks of the box and replacing it by a movable cheek, A, suspended from a strong tenon or pin, F,

out out from the upper block, the oil-reservoir of which is again closed by fixing to the block from 'our invention, and that the same is not only applicable to locomotive-axles, but also to other railway-carriage axles, and to any other axles which are subjected to frequent displacement, such as axles of steamboats.

Vhat we claim is .An axle-box having one or two movable cheeks, A, connected with the upper part of the box by studs or guide-pins F, and inclosing three bushes, C O 0, held in place by lateral flanges only, and adapted (as regards their height and width) to allow the two vertical bushes 0 vertical play without hinderance from the third bush, 0, or from the box, and to allow the upper bush, 0, horizontal play 20 without hinderance from the two other bushes or from the box, substantially as described, and illustrated by the drawings.

In testimony whereof we have signed this specification in the presence of two subscrib- 2 5- ing witnesses.
