UNITED STATES PATENT OFFICE.

JOURNAL-B OX.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed February 6,1907. Serial No. 356,056.

To all whom it may concern:

Be it known that we, SAMUEL REYNOLDS and SAM- UEL J. REYNOLDS, citizens of the United States, residing at Plymouth, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Journal-Box, of which the following is a specification.

This invention relates to a car axle journal box of that general class constituting the subject matter of the U. S. Letters Patent No. 717,452, granted to us on the thirtieth day of December, 1902.

The invention has for one of its objects to simplify and improve the construction of journal boxes of this character so as to be durable and substantial, comparatively easy and inexpensive to manufacture, and reliable in service.

Another object of the invention is to provide an improved lubricating system whereby the car axle and bearing block are thoroughly lubricated. I

With these objects in view, and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention Figure 1 is a front elevation of the journal box. Fig. 2 is a vertical section thereof. Fig. 3 is a central vertical section taken at right angles to that of Fig. 2. Fig. l is a plan view of the bearing block.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Referring to the drawings, 1 designates the body of the journal box which comprises a casting or other metal structure composed of a flat top 2 provided with parallel upwardly extending flanges 3 and 4, the latter of which is chambered to form a lubricant reservoir 5. The underside of the body is chambered to receive the journal of the car axle and bearing block. This chamber is provided with a flat top wall (3 and downwardly converging walls 7, so as to form a dovetailed groove, the said groove being open at the rear of the body and closed at the front by transverse wall or abutment 8, Figs. 2 and 3. ln this dovetailed portion of the chamber is confined the bearing block 9. The block is assembled through the rear open end of the dovetailed groove and is prevented from working out by the wall or abutment S at the front and the shoulder 10 of the axle collar at the rear, as indicated in Fig. 3. Since the wall 8 is an integral part of the journal box body, the bearing block is positively held in place.

The walls 7 are undercut to form the oppositely disposed grooves 11, Fig. 2, for receiving the slide 12 of the journal box, which is provided with longitudinal flanges 12 engaging in the said grooves. As shown 1 by dotted lines in Fig. 3, the grooves 11 terminate short of the rear surface of the body 1, as indicated at 13, and the end walls of the grooves form stops for engaging with the rear ends of the flanges 12. The front of the slide is closed by a vertical wall 14, so that a comparatively dust proof bearing is produced. On the front face of the body 1 is a slotted lug 15 for receiving a cotter pin 16 that extends over the front of the slide 12 to retain the latter in position. Should this pin accidentally drop out and the slide 12 become detached, the journal box will be practically unimpaired and the car will continue to run until a new slide is obtained to replace the lost one.

To supply the lubricant to the journal 17 of the axle, the bearing block 9 1s provided with a plurality of inclined passages 18 adjacent each end, and one pair of these passages is adapted to register with openings 19 in the floor of the chamber or reservoir 5. The top surface of the bearing block is hollowed out in the form of two basins 20 that are connected by a channel 21. By means of these basins and connecting channel, lubricant can be fed to the axle through the passages 18 alining with the openings 19 and also through the passages 18 at the opposite end of the bearing block, so that the axle journal is thoroughly lubricated at both ends. The passages 18 are symmetrically arranged for the purpose of permitting the bearing block to be reversible. The chamber or reservoir 5 has a filling opening 22 which is closed by a hinged cover 23 for excluding foreign matter. If desired, a body of waste may be employed in the chamber 5 to serve as a filter for preventing grit from passing to the axle journal.

The journal box is attached to a car truck by presenting it to the underside of one of the side beams of the latter with the flanges 3 and 4 engaging, respectively, the rear and front faces of the beam. The top 2 of the body 1 is provided with apertures 24 for the reception of the bolt that secures the box to the truck beam.

- What is claimed is A car axle journal box comprising a body having; a lubricant reservoir and an axle receiving chamber, a bearing block fitted in the chamber and provided with passages adjacent its ends and connected basins on the top surface of the bearing block, and a removable member on the body for closing the underside of the chamber, the bottom of the said reservoir being provided with openings for supplying lubricant to the passages and basins of the bearing block. In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two Witnesses.
