lSPECIFICATION forming part ot Letters Patent No. 252,357, dated January 17, 1882,

i Application filed September 12, 1881. (No model.)

Beit known that I, JENNIE R. CooPER, a citizen ofthe United States,residing at Union City, in the county of Erie and State of Penn- Sylvania, have invented new and useful im- Vforlubricatingthejournals ofcar axles in which the oil is conveyed from the reservoir to the 15 `journal byaroller which is in frictional contact with the journal, and is thereby revolved and is also partially immersed in the oil in the reservoir, and by thus revolving whileso immersed conveys the oil from the reservoir to the journal.

My invention consists in providing.,r 'such an apparatus with certain improvements in construction and operation, as is hereinafter fully described, and designated by the claims.

My invention is illustrated in the accompanying drawings as follows Figure l is al longitudinal section taken on the line 1 l in Fig. 2. Fig. 2 is a transverse vertical section taken on the line 2 2 in Figi. Fig. 3 is a top or plan view of the oil-reservoir and conveying-roller. Fig. 4 is a perspective viewT of said reservoir with the roller removed. Fig. 5 is a perspective view, on a larger scale than the foregoing, of the said reservoir, with partsbroken oi, so` as to show internal construction. This view also showsthe roller in place. Fig.6 is a longitudinal vertical section ot' the oil-reservoir on the same scale asin Fig. 3, and shows also an alternative construction of the spring supporting the roller. Fig. 7 is a perspective view of the spring which is shown in Fig. 6.

The parts shown in the drawings are designated by letters of reference as follows:

A represents an ordinary car-axle box, A',

the cover to the same. Bis the car-axle proper, and C the journal of the saine. I) is the oilreservoir,which is a metallic box or bowl,sep

arate and distinctfrom the box A, and sets Within the saine below the journal C. it is divided into two partsa reservoirchamber and a hopper or dishing top. f E is the roller; e e,

the journals ofthe roller ;ff, the springs supporting the roller in properposition. ffare i the alternative/forms of springs for supporting the roller. g gg g are guides for keeping the roller in proper position vertically. dtd

are lugs for keeping the springs ffin proper in place by vertical guides, and sustaining it" in Contact with the journalbyspriugs, to which the roller is journaled; third, making the oilreservoir a separate and detachable vessel, and providing it with a hopper-shaped top for catching the drippings of oil from the journal.

The construction and arrangement of parts are as follows: i

First, ofthe roller. I aml aware that rollers of various construction have heretofore been used for the purpose herein shown.. My device consists of a roller having tufts ot' bristles arranged upon its body, as shown in Figs. l and 3. The object of this construction is to facilitate the operation of conveying the oil to thejournal. The bristles should not be very long, and should be as stift' as possible. However, to insure the rotation of the roller when the bristles become too pliable, the roller or its shaft or journal may be provided with a bearing-surface of wood, metal, or any hard substance, which will be so arranged as to come in direct frictional contact with the journal ofthe axle. Such a construction is shown in Fig.1 and marked E.

Second. The devices for keeping the roller in place vertically and keeping it in frictional contact with the journal of the axle are as fol` lows: These devices, in other word-s, constitute the hangings ofthe roller. Lugsg g g gat the ends ofthe openingin thetop ofthe oil-reservoir form `guides for thejournals ot' the roller, permitting vertical movement of the roller, but preventing lateral movement. supported by a wire, j', at each end, which is bent so as to form a spring and Ialso a journal-bearing for the roller. These are shown clearly in Figs. 2 and 5. In Figs. 6 and 7 an alternative construction is shown tor the spring. The feet of the springs frest upon the bottom of the oil-reservoir, and are kept in place by The roller is guides d', which are lugs east on the bottom of the reservoir. These devices for hanging the roller maybe used for any kind ot' a. roller, Whether plain or prepared with bristles cr covered with felt or other absorbent.

Third. The oil-reservoir D is made with an oil-compartment, d, and with a Haring hoppershaped top. The opening between the two is occupied bythe roller The wholedeviee is made so as to be set into the axle-box A, as shown in Figs. 1 andf2, and may be taken out for cleaning and repair at any time. It may be made ot' cast metal, all in one piece, or'of sheet metal, such as tin, if desired. The hopper-shaped top Bares out and reaches up bythe side of the axle-journal C, so as to catch the spatterings and drippings ot' the oil.

The exact form of parts, as shown, is not strictly essential, as they may be varied without affecting the object and purposes sought by my invention.

What I claim as new is as follows:

1. In a car-axle-lubricating devioe,the oilconveying roller provided on its surface with tibrousand absorbent material, and a tractionsurfaee, E', in direct contact with the axles, substantially as and for the purposes set forth.

2. In a car-aXle-lyubrieating device, the combination, with the journal ofthe oil-conveying roller, of the vertical guides g g, supportingspringf, haring its feet resting upon the reservoir tloor or bottom, and the guides d, located, as shown, to prevent the feet of springf from slipping laterally, all combined and arranged substantially as described.

3. An oilreservoir for car-aXle-lubrieating de\"iees,having` a hopper shaped top forcatching` the drippings, vertical guides for the journals of a roller, 'and lateral guides upon the floor, for the purpose settorth, in combination with aroller haviugsprings attached to thejonrnal and resting upon the door between the side walls and lateral guides, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this Sth day of September, 1881.
