JOURNAL-BOX.

Specification of Letters Patent.

Patented Apr. 11,1916.

Application filed May 26, 1914. Serial No. 841,060.

a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a journal box, and more particularly to the means within thri, box to resiliently support the car on the ax e.

An object of the invention is to provide a device of this character which will effectively prevent hot'boxes.

A further object of the invention is to provide spring pressed means within the box which will effectively prevent the oil soaked waste from working between the axle and the means for supporting the car thereon.

With these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as herein set forth and subsequently claimed.

Referring to the drawing: Figure l is a perspectiveview of the device. Fig. 2 is a side elevation of my device with parts broken away showing the position of the several parts when weight is relieved from the axle. Fig. 3 is a longitudinal section showing the several parts in operative position. Fig. 4 is a perspective view of the axle therefor. Fig. 5 is a transverse vertical section. Fig. 6 is a transverse vertical section showing the dust guard.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views: My device comprises a journal box having horizontally disposed top and bottom portions 1 and 2 and sides 3 formed integrally therewith, which sides converge upwardly. Formed on these sides are transversely extending flanges 4 forming a groove 5 therebetween by means of which the box is attached to a car.

The nds 6 and 7 of the device have openings 8 and 9, respectively, formed therein. The opening 8 on the outside of the box is closed by a cover 10 pivoted to an ear 11 on the box and adapted to be swung over said opening.

An axle 12 extends through the opening 9 and into the journal box and terminates short of the opening;8. Mounted on the 'axle 12 is a slide 13 which has a hole 14 therein through which the axle extends and is rotatable. This slide 13 is arranged within the journal box adjacent the opening 9 and is adapted to 'close'the same. The

sides of this slide 13 converge upwardly and the width of the slide is less than the width of the box so that as the axle 12 rides upwardly and downwardly in the box I the slide will move with it and through the slots 15 and 16 in the upper and lower portions 1 and 2 of the box adjacent the end 7. By using this slide dust is efiectually prevented from entering the box from this end.

Mounted on the portion of the axle 12 within the journal box so as to lie on the upper side of the said axle is a substantially rectangular elongated strip of metal 17 preferably made of brass. The under face of this strip 17 is concaved so as to fit the periphery of the axle. A double leaf spring 15 is interposed between the top 1 of the journal box and the strip 17 to maintain the strip in operative relation to the axle. This spring is formed of two flat members 19 and 20, secured together at 21, the ends of the lowermost member 20 curve downwardly and bear against the ends of the strip 17, while the ends of the member 19 curve upwardly and bear against the ends of the top 1. I

The usual oil soaked waste is put in the box below the axle 12 so as to be in contact with the lower portion thereof and thus supthat hot boxes are caused by this waste working between the axle supporting means and the axle itself. In my device, however, the spring always maintains the strip in contact with the axle 12 so that there is no possibility of the waste getting between the said strip 17 and the axle, and thus there is no possibility of hot boxes resulting.

From the foregoing description it may be seen that I have provided a journal box and a spring within the same for maintaining the axle supporting means in its operative position in such manner that there will be no possibility of the oil soaked waste con tained in the box getting between the axleis obvious that numerous changes may be made Within the scope of the invention as defined by the claims.

What is claimed is:

1. In a journal box, a metallic strip having a longitudinally eXtending groove in the under face thereof adapted to receive an axle spindle, the said strip having also upwardly extending lugs at the ends thereof, an upwardly bowed leaf spring having its ends bearing against the said lugs and a downwardly bowed spring secured to the first mentioned spring and having its ends bearing against the top of the journal box.

2. In a journal boX having slots in the top and bottom portions thereof, a slide mounted in said journal box and extending through said slots, said slide having a hole therein adapted to receive an axle spindle and resilient means adapted to act through the said spindle to maintain the slide in its lowermost position, normally.

In testimony whereof, I my signature, in the presence of two Witnesses.
