Serial No. 264,109.

To @ZZ 1.071.071?, it '1n/ty concer-rt:

Be it known that 1, ALONZO H. LAY'roN, a citizen ol the United States, residing at llliance, in the county of ,loxbutte and @tate ot Nebraska, have invented a new and useful Lubricatingdourual, ot which the following is a specilication.

This invention relates to jeurnal-bearings, more particularly to the bearings ot railwaycar axles, and has tor its object to provide a simply-constructed and easily-applied device whereby the bearing may be continuously and automatically lubricated and the `lubricant supplied only so last as needed, thus insuring uniform application ot' the lubricant and prevent wasteful use ol the saine.

With these and other objects in view, which will appear as the nature ot' the invention is better understood, the same consists in certain novel features of contrilction, as hereinafter fully described and claimed.

In the accoiniianying drawings, forming' a part oi this specilication, and in which corre spending parts are denoted by like designan ing characters, is illustrated the preferred form of embodiment oi the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrilicing any oiu its advantages.

ln the drawings, Figure 1 is a longitudinal sectional elevation of the improved device applied to a railwaycar-axle bearing. Fig. 2 is a transverse section on the line 2 2 ol' Fig. l. Fig. 3 is a transverse section ot the improved device on the line 3 3 of F ig. 1. Fig. a is a detached perspective view, enlarged, et' the improved device. Fig. 5 is a sectional detail illustrating the construction when applied to axle-bearings not having end flanges.

The improved device comprises a hollow casing 10, having at one end a reservoir 11 for a supply ot' lubricatingl material and communicating by ports 12 13 at the sides with the interior of the casing. The upper Vtace let of the casing 10 is concaved in general conformity to the axle-bearing represented at 15, but ot' greater radius, and disposed in this con caved portion are spaced longitudinal ribs 16 17, the ribs connected at the ends by transverse ribs 18 lil, curved to corresijioml to the liearing. The longitudinal ribs 16 17 are also curved transversely in conformity with the bearing, so that the latter bears uniformly upon all the ribs. F led-apertures 2O connect the interior oli the casing lll with the area within the ribs 16 17 18 1), so that the lubricant will 'flow therethrough, as will be obvious.

liletween the casing 10aud the adjacent 'face ot the axlesbox 21 are springs 92 233, operating to hold the casing y ieldabl yin engagement with the bearing and secured by a keeper 2&1.

llt/'hen the device is applied to a bearing having an end flange 25, as in Figs. 1 and 2, a well 26 is Yformed in the casing to receive the same, as shown; but when applied to bearings not having end [langes the well portion will not be required, as illustrated in liig. 5.

ft. feed-aperture 2T is formed in the reservoir 1l, through which the lubricant is introduced by means ot any suitable spout inserted through the usual detachable cap member 2510i" the axle-box. By this simple construe tion with the reservoir 1l lilled with lubricating material, such as the grade of oil usually employed for axle-bearings, the same will ilow by gravity through the ports 12 153 and thence up into area delined by the ribs 16, 17, 18, and. 19 and against the bearing. As the bearing rotates a limited amount ot' the lubricant is carried upward and beneath the bearing member 29; but only a sul'licient amount of the lubricant will be thus carried to properly lubricate the bearing, leaving the surplus in the cavity within the ribs. .lhus ne waste ot the lubricant occurs, and any small surplus which may be carried past the ribs 16 or 17, as the case may be, will run back into the portion of the concave recess in the member 10 and be there retained and not ilow over the sides olf the same.

lhe device will operate with equal el'liciency without regard to the direction elI motion oi the journal.

'lhe head oi oil in the reservoir 11 will insure the constant and uniform supply to the distributing recess or cavity within the bearing-ribs, as will be obvious.

Having thus described the invention, what is claimed 1. .ln a device ot the class described, a casing having a comn'iunicating lubricant-reservoir at one end extending above the saine and with a convex upper surface havingl longitudinal |)cz'1,ring-ribs spaced apart and connected at by transverse bearing-ribs curved to conform to said journal and bearing beneath the same, said Casing having feed-apertures within the area defined by said ribs.

In testimony that I elarn the foregoing' as my own I have hereto aXed my signature in the presence of two witnesses.

ALONZO H. LAYTON.
