C COLLINS SHAFT LUBRICATING DEVICE Flled May 5 1924 Patented Sept. 8, i925.

CHARLES COLLINS, OF

MGVEIGH, KENTUCKY.

SHAFT-LUBRIGATING DEVICE.

Application filed May 3,

To all whom t may concern.'

Be it known that I, CHARLES COLLINS, a citizen of the United States, residing at Mc- Veigh, in the county of Pike and State of Kentucky, have invented certain new and useful Improvements in Shaft-Lubricating Devices, of which the following is a specitication.

This invention relates generally to the art of lubrication, and has more particular reference to a means for supplying a lubricant to rotary shafts, the invention relating specifically to means adapted to be disposed within the oil cellars of railway car journal boxes for dispensing with the usual lubricant applying waste.

In the use of waste in journal box oil cellars for carrying the lubricant to the car axles, the same oftentimes becomes depressed or forced downwardly within the oil cellar and this especially when the car runs off the track. After the Car has been rerailed, the waste obviously will not again move upwardly with the raising of the axle, and this is generally the cause of improper axle lubrication now incident to the opera tion of railway cars.

It. is therefore the primary object of the invention to provide a device that is adapted to be mounted in the oil cellar of a journal box, wherein the lubricant will be at all times carried to the axle wherein the lubricant .applying means per se, will be in permanent contact with the axle, and will move upwardly and downwardly with such movements of the axle in the journal box.

A still further object of the invention is to provide a lubricating device that may be installed and maintained indenitely at a minimum cost, the device being relatively simple of construction, and the parts so correlated as to reduce the possibility of disf arrangement to a minimum.

'IV ith the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the drawings and claimed.

In the drawing wherein like reference characters indicate corresponding parts throughout both of the views:

Figure 1 is a detail sectional view through a car axle journal box, within which is dis- 1924. Serial No. 710,814.

posed a lubricating device, constructed in accordance with the present invention, and Figure 2 is a top plan view of my invention per se.

Now, having particular reference to the drawing, indicates generally a railway car journal box, within which extends the car axle 6.

My invention constitutes the provision of a substantially rectangular shaped sheet metal plate 7, that is adapted to be disposed within the oil cellar of the box 5 in substantially the manner shown in Figure 1. The four corners of this sheet metal plate 7 are equipped with any desirable form of adjustable supporting legs 8, whereby said plate is supported in position above the bottom wall of the box 5. The

front and rear edges of the plate 7 are formed with upstanding flanges 9, pivoted to the inner sides of which are pairs of links 10. Between the alined links on the opposite flanges 9 are journaled roller members, preferably of wood 11-11. These rollers are formed centrally with circumferential grooves 12 trained within which are chains 13. These chains 13 manifestly hang downwardly and the same engage through the transverse slot 14 in the plate 7, and at all times the lower ends thereof are submerged within the oil in the box cellar.

These rollers 11 are adapted for permanent engagement with the axle 6, and in bringing about this result, the links 10 at the opposite ends of the rollers are interconnected through the medium of tension adjustable springs 15.

It will thus be seen that the springs 15 normally tend to bring the rollers 11 towards each other, which will of course maintain the same in permanent contact with the axle 6. The pivotal mounting of these rollers allows the axle to move downwardly within the box, in the event that the car becomes derailed without disrupting the mechanism of the lubricating device. When the axle returns, the rollers will also return, and incident to the rotation of the axle, the rollers 11 will be rotated, and this action will operate the chains for bringing the oil from the well upwardly onto the axle.

I do not wish to be limited to the exact structural details shown or described, as in the future practice of the invention, minor changes may be made therein without departing from the spirit and scope of the ap pended claim. o

Having' thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

In a lubricating device of the class described, a plate having a slot therein, means for supporting the plate above the bottom of the oil cellar` of an axle journal box, a pair of upstanding flanges on the plate, two links pivoted to each lange, a pair of rollers pivoted to the upper ends of the links,chains trained over the rollers to hang therefrom, a. spring engaging the links on one flange tending to hold the rollers in engagement with an axle, and tensioning means incorporated in the spring.

In testimony whereof I aix my signature.

CHAS. COLLINS.
