SPECIFICATION forming part of Letters Patent No. 670,642, dated March 26, 1901. Application nea August 3,1900. sentito. 25,764. (remodel.)

To all whom it may concern,.-

Be it known that I, WILLARD F. RICHARDS, a citizenof the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Oar-Axle Boxes, of which the following is a speciiication.

This invention relates to car-axle boxes in which the lid 'is hinged at its upper end to thev top of the box.

The object of my invention is to provide thel lid with simple-means for insuring a dustproof jointbetween the body of the box 'and the top, bottom, and sides of the l-id.

In the accompanying drawings, Figure l is a fragmentary longitudinal section of a journal-box providedwith my improved lid, showing the latter closed. Fig. 2 is a similar section showing the lid open. Fig. 3 is a detached inside View of the lid, showing the grooved enlargement at its upper end in section. Fig. 4L is a detached face View of the lid.

Like letters of reference refer to like parts in the several figures. i

A is the body of the boxprovided in its outer end with the usual filling-opening a,

- having the raised rim a.

B is the lid, which is hinged at its upper end to the top of the box by a horizontal pin C. This pin passes through the usual eyes or sleeves b at the top of the lid and through a lug D, projecting upwardly from the top of the axle-box.

E is the usual flat spring for holding the lid in its closed position. This spring is secured at its lower end to the lid, and its free upper end bears against the front side of the Ahinge-lug D. The lid is provided at its unper end with the usual raised hood F, which incloses the lug D and the spring E. This hood extends upwardly and rearwardly over the top of the hinge-lug D and terminates in ahorizontal enlargement f, which is arranged on the rear side of said lug. This enlargement is provided in its inner side with a horizontal groove f', in which is seated a packing g, of hemp rope or other suitable material, which projects beyond the groove and bears against the rear side of the lug D, so as to close the joint between the hood F and said lug and effectually prevent the entrance of dustat that point. The groove f is preferably undercut or somewhat greater than a semicircle in cross-section, as shown, so that the packing must be forced into the'same, thereby reliably retaining the packing in place. The upper rear portion of the hingelug D, against which the packed enlargement fof the hood F bears in the closed position of the lid, is flattened and inclined rearwardly, as shown at h, and the inner side of said enlargementis correspondingly flattened and beveled. The hinge-pin of the lid is usually fitted with more or less looseness in the lug D owing to the roughness of the castings. The spring E tends to forcethe upper edge of the lid away from the box, and unless some means is provided for resisting this action of the spring a gap is left between the box and theupper portion of the lid through which dust enters. The packed enlargement fat the upper end of the lid by bearing against the inclined rear face of the hinge-lug D prevents the spring from drawing the lid away from the box, whilethe packing in its groove forms a dust-proof joint between the hood of holds the lid in its open position.

The lid is provided on its inner side, opposite the raised rim of the filling-opening a, with a groove or depression I, in which is seated a packing i, of hemp rope or other suitable material, Which bears against said raised edge when the lid is closed, as shown in Fig. 1, thereby forming a reliable dust-proof joint. The packing-groove I is arranged parallel with the lower and side edges of the lid, and the horizontal upper portions z" thereof,which are arranged on the lower side of the piutleeyes b, terminate at the sides of the hood F, as shown in Fig 3. The packing-groo ve I is preferably somewhat greater than a semicircle in cross-section, similar to the groove of the enlargement f, so as to confine the packing in the groove. The lid is provided on its inner face, on the inner and outer sides of the packing t, with inwardly-projecting IOO langesj I7", which overlap the edge of the filling-opening, as shown in Fig. l, thereby aiding in preventing the entrance of dust into the axle-box.

l claim as my inventionl. The combination with a journalbox having aperforated hinge-lug, of a lid hinged to said lug and having a closing-spring which bears against said lng, and provided at its upper end with a packing which bears against the rear side of said lug, substantially as set forth.

2. The combination with a journal box having a perforated hinge-lug, of a lid hinged to said lug and having a closing-spring which bears against said lug and provided at its upper end with a groove which faces the rear side of said lug, and a packing seated in said groove and bearing against said lug, substantially as set forth.

3. The combination with a journal box having a perforated hinge-lug, of a lid hinged to said lug and having a closing-spring Which bears against said lug, and provided at its upper end With a groove which faces the rear side of said lug and which is greater than a semicircle in cross-section, and a packing confined in said groove and bearing against said lug, substantially as set forth.

4E. The combination with a journal box having a perforated hinge-lug, the upper rear side of which is flat and inclined rearwardly, of a lid hinged to said lug and having a hood which incloses said lug and which is provided at its upper end with an enlargement arranged on the rear side of said lug and having an inclined or beveled inner face, said enlargement being provided in its beveled face with a horizontal groove, and a packing seated in said groove and bearing against the inclined rear face of said lug, substantially as set forth.

Witness my hand this 28th day of July,

WILLARD F. RICHARDS. Witnesses:
