To all whom it may concern.-

Be it known that I, CLARENCE D. DEWEY, a citizen of the United States, residing at Hawley, in the county of Wayneand State of Pennsylvania, have invented certain new and useful Improvements in Car-Journals, of which the following is a specification ref erence being had to the accompanyingdrawln s.

This invention relates to an improved car journal and has for its primary object to provide a self-lubricating roller bearing journal for car wheel axles whichis so constructed as to permit of a longitudinal thrust of the wheel axle when the wheel comes in contact with a curved section of the rail, switches, guard rails, frogs, and the like.

It is another important object of the invention to provide a car journal wherein friction is reduced to a minimum, the journal being constructed of relatively few parts which are all of simple form and may be easily and quickly assembled in the journal box.

With theabove and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which, 4

Figure 1 is a vertical sectional view of a car journal constructed in accordance with thed preferred embodiment of the invention; an

Fig. 2 is a section taken on the line 2--2 of Fig. 1.

Referring in detail to the drawing, 5 designates the car wheel axle upon which, in spaced relation to each of its ends, the car wheel 6 is suitably secured.

The journal box 7 may be mounted or arranged in the under frame of the car in any approved manner. The inner end wall of the box is provided with an opening 8 through which the wheel axle is loosely dis top wall. This latter end of the journal box is adapted to be closed by means of a plate detachably secured to the box in any preferred manner.

10 and 11 designate the upper and lower sections of a cage or retainer for the bear-- ing rollers 12, which surround the reduced end of the car wheel axle 5. These rollers are disposed between the spaced, annular shoulders 13 at the opposite ends of the reduced portion of the axle. The two sections of'the cage or retainer are in the form of rectangular metal castings which are provided with concave faces 141 disposed in concentric relation to the car wheel journal or axle when the retainer sections are assembled within the journal box in opposed relation to each other above and below the axle. The sections 10 and 11 are also'each pro vided with outwardly projecting flanges 15 along its longitudinal and end edges and an inwardly projecting flange 16 at each end of the concave face 14c. The latter flanges provide additional means for preventing relative longitudinal shifting movement of the rollers 12.

The top wall of the journal box 7 is also provided upon its inner face with longitudinal flanges 17 in opposed relation to the corresponding flanges 15 upon the top section 10 of the retainer. Between this top wall of the journal box and the retainer section 10, a series of rollers 18 are arranged, said rollers being rotatable between the end flanges 15 on the retainer section. The rotative axes of the rollers 18 are disposed at right angles to the axes of the bearing rollers 12.

Beneath the lower section 11 of the retainer, a vertically adjustable plate 19 is arranged in the journal box 7. This plate is adjusted by means of a plurality of screws 20 having threaded engagement in the bottom wall of the journal box, said plate resting upon and being supported by said screws. Shoulders 21, formed upon the side walls of the journal box at its outer end, act as stops to prevent the outward shifting movement of the plate 19. This plate is provided upon its longitudinal. and end edges with. upstanding flanges 22, and between said plate and the bottom face of the lower retainer section 11, a series of rollers 23 are arranged. The axes of these rollers are disposed in parallel relation to the rollers 18, but preferably the rollers 23 are smaller in diameter than the rollers 18, and a relaively large number of the rollers 23 is employed. The rollers 23 support the lower retaining section 11 for free longitudinal movement Within the journal box, and reduce friction on said retainer section to a minimum.

It will be observed that the retainer sections 10 and 11 are of less length than the internal longitudinal dimension of the journal box. Thus, in the operation of the device, when the wheel 6 engages a curved portion of therail or strikes a switch frog or guard rail, the longitudinal thrust upon the Wheel axle is transmitted through the rollers 12 to the retainer sections 10 and 11 which slide or move longitudinally upon the rollers 23 within the journal box. This shifting movement of the retainer sections .is limited by the engagement of the outer end of the upper section 10 with the depending fiange 9 on the top wall of the jours nal box. The lower retainer section 11 provides an oil cellar, and a suitable lubricating oil is placed within the same around the rollers 21 so that as said rollers rotate, they automatically apply the lubricant to the periphery of the wheel axle. When it is desired to remove the rollers to replace the same with new ones or otherwise repair the journal, the screws 20 are properly adjusted to 'lower the plate 19, and the cap plate on the end of the journal box is removed so that the lower retainer section 11 may be drawn outwardly through the open end of the journal box. The rollers 12 can then be readily removed and the top section 10 of the retainer also withdrawn.

From the foregoing description, taken in connection with the accompanying drawing,

the construction, manner of operation and several advantages of the device will be clearly and fully understood. My improved journal is verysimple and durable in its construction and entirely eliminates the transmission of shocks and jars to the body of the. car, owing to endwise thrust upon the wheel axle or journal. The several elements employed can also be very easily and quickly assembled in their proper operative positions Within the journal box, and as readily removed therefrom.

While we have shown and described the preferred construction and arrangement of the several parts, it is to be understood that the device is susceptible of considerable modification therein and I, therefore, reserve the-privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is I 1. The combination with a car wheel journal, of a journal box, roller retainer sections arranged within the box above and be mes es Q low the car journal, bearing rollers arranged within the retainer sections around the our- 'nal and in parallel relation to the latter,
