CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 394,096, dated December 4, 1888.

Application filed July 2 7, l 8 8 7.

T0 all whom it may concern.-

Be it known that we, WILLIAM HENRY BUR- DEN and FREDERTCK CHEEVER BURDEN, of Cleveland, county ot Cujfahoga, State ot' Ohio, have invented certain new and uset'ul lmprovements in Car-Journal Lubricators, ot' which the following is a speciticatioii.

This invention relates to a device for conveying oil to the journals in car-axle boxes; and it consists in the peculiar construction and combination ot' the parts adapted to be placed in the journal-box below the journal for feeding oil to the central part ot the journal in small quantities sufficient to lubricate the journal without waste. It is also so constructed to exclude dust and dirt from the oil, and is arranged to operate in combination with the journal, substantfialljv as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a if'ertical and longitudinal section ot' a carjournal-box having our device attached, showing its location and manner ot' working in connection with the journal, Fig. 2 is a vertical cross-section on line 2 2 ot' Fig. 1. Fig. P3 is a top or plan view of our lubricating device detached. Fig. et a side elevation ot' the same, partly in section, showing an inner cup or chamber for holding oil. Fig. 5 is a detached sectional view of the feed-roller.

A represents a car-journal box, and l is the journal. C is the bearing Afor the journal. These may be of the common and well-known kinds and construction.

Our device is constructed as follows:

D is a frame or plate having an upright flange, E E, at each end. To the said vflanges are secured, byrivets or other suitable means, plates of heavy leather, F F, or other suitable material, preferably leather, on account of its elasticity. The upper sides ot the said flanges E and plates F are cut out to fit up and partly embrace the journal B. To the under side of the plate or frame D is secured a spring, G, which also bears upon the bottom of the box and serves to support and hold the device up to the journal.

H is a feed-roller, consisting' of a worm- Serial No. 245,409. (No model.)

wheel and shaft set in bearings I l on the under side of the frame or plate D.

J .l are two rings located one on cach side of the worm-wheel, and are attached bvlneans of diagonal spokes, forming cone shaped frame-work at each side ot' the said worinwhecl. The rings .I J are ot a little greater diameter than the worin-wheel, and they, t0- gether with the worin-wheel, project a short dist-ance above the trame D through an opening t'or that purpose, and the said rings onljv are in contact with the journal l, by which the said feed-roller derives its rotary motion.

K is a volte having eyes which lit on the shaft of feed roller loosely and permit freedom of play thereon, while the arm k of the voke may lie on the bottom of the box.

L is a gear-wired journaled on a pin or rivet, R, in the lvolte, and with its teeth meshing with the wor1nwheel, and from which said gear-wheel derives rotary motion. The yoke is made in two parts, and the rivet R, which serves as the pivot for the gear-wheel, also serves to secure the two parts of the yoke together.

It desired, an inner box, M, fitted to hang suspended from the frame D and within the spring G, to contain the oil and the mechanism for feeding it, may be employed for the purpose of providing a safeguard against the ingress of dirt.

The operation of this device is as follows: The revolutions of the journal B imparta rotarjv motion to the feed-roller H, and from thence to the gear-wheel L, which reaches down into the oil. The oil is thus conveyed in the teeth of said geaiwheel to the wormwheel, from which it is taken up by the journal b v capillary attraction at its middle part, and therebyv supplying the lubricant to the journal-bearings.

From the foregoing' it will be seen that this device possesses the following advantages. It feeds the oil in small but sufcient quantity and to the central part of the journal, from whence it is equally distributed along the bearing. It accommodates itself to position under the journal under all conditions, preserving the alignment of the feed-roller with the journal, thus avoiding friction. It incloses the oil in a practically-tight box, thus securing it against the ingress of dust or dirt, there by preserving the oil free from grit.

Having described our invention, We claim as follows:

lr. The feed-roller consisting of a shaft li aving a Worin-Wheel on its central part, and the rings flanking said Worin-Wheel and attached by diagonal spokes, substantially as described.

2. The Afeed-roller consisting of a shaft, Worm-Wheel, and rings, as described, and a gear-Wheel pivoted to a yoke fixed on the shaft of said feed-roller and meshing with the said Worin-wheel, substantially as described.

3. The feed-roller consisting of' a shaft, a Worm-Wheel, and rings, as described, a yoke fixed on the shaft of said roller and carrying the gear-Wheel, in combination With a plate or franie having the curved-out flanges and end plates and supported on a spring constructed and operating substantially as and for the purpose specified.

4. The end plates, in combination with the frame or plate supporting a feed mechanism in a journal-box, whereby dust and dirt are excluded from the journal, substantially as described.

5. The end plates, in combination with the flanges of the frame or plate, each having the curved-out space, substantially as described.

'6. The feed -roller consisting of a shaft, Worin-Wheel, and' rings, as described, a yoke fixed on the shaft of said feed-roller and carrying the gear-Wheel, in combination With a plate or frame having the curved-out flanges and end plates, the supporting-spring, and an inner box or cup containing oil and inclosing the feed mechanism, substantially as described.

7. The end plates attached to the fianges and each having the curved-out space, in combination with the feed-roller consisting of a shaft, worm-Wheel, and rings, as described,
