To aZZ whom z't'may concern. l to supplythe demand ofthe axlein such man;

Be it known that I, ADDISON BRADFORD, of ner that the said supply willbe pure, clean oil, Brooklyn, in the county of Kings and State of devoid of such impurities as would rise if the New York, have invented certain new and use lubricating-wheels were constantly in contact 5 ful Improvements in 'Lubricators; and I do with the oil, all of whichwill more fully herehereby declare that the following is a full, inafter appear. A- lubricator for ear axle clear, and exact description thereof, which 'journals needs to be so constructed as to be will enable others skilled in the art to which readily applied to the journal while in its .1t appertains to make and use the same, referplace in the journal-box, and readily adapt IO ence being had to the accompanying drawings, itself to the varying sizes and shaped boXes and to the letters of reference marked thereon, and j ournals, also the varying movements and which form part of this specification. conditions of the journal and box as they re- This invention relates to mechanical conlate to each other. In this lubricator all these trivance for applying lubricants to journaldemands are met by its construction and adapt- I 5 bearings, and particularly to the bearings and ability.

The conoil, whereby the lubricating material is prestruction consists of a set of wheels or rollers vented from becoming gummy and thick, and journaled and mounted between .suitable whereby the desired quantity alone is supplied frame-pieces, said wheels or rollers being jour; to the journal and bearings, as will hereinafter naled in movable bearings adapted to slide in 25 more fully appear. slots or grooves in the framework, and are The invention consists in providing a frame held together "by springs in connection with of peculiar construction, to which is attached the bearings, so that the wheels are brought waste-preventing rubbers at one end, which close together by the tension of the springs. act spring-like in maintaining said rubbers in The purpose for which they are thus journaled 0 contact with the journal, and at the other end and held together is that when in position they are mounted lubricating rollers or wheels.

These extended arms ing said box with lubricating material through pass on the bottom of the box, under the joursmall apertures or through some porous manal, till the ends press against the rear end of terial in such quantities as will be sufficient the box, when the lubricator is raised to an u y right position, and the bail-handle or brace, connected with the upper part of the framework, is placed inside the end of the box by the door, thus holding the lubricator in a firm upright position. To said arms are attached springs with suitable bearing ends, that bear against the inner portion of the journals bearing to take off the surplus oil inside the journal-box, to prevent its escape and waste by following the journal outside the box. Fig. 3 shows the frame-work in which the wheels or rollers are journaled in a closed framework, except a suitable opening at the end or elsewhere is covered with a porous substance or perforated material, or a small hole is left open near the bottom, for the purpose of supplying the wheels with but a moderate amount of oil; also to prevent agitating the oil by running the wheels in it. Fig. 4 shows the journal of the rollers'and bearings in section.

In the drawings, A represents a journal-box of a railroad-car, B the brass or bearing, and G the axle-journal, all of ordinary construction.

On the bottom of the box is the frame D D,

between which are the oilerrolls F F, working on shaft 0, provided with conical journals, and which work in like bearings, 1 which are adapted to slide in an elongated slot, h, and held in a yielding position by means of springs c 0, one being on each side of the frame D D.

Attached to frame D is a hinged frame, F, extending longitudinally along the bottom of the box, and to which is attached two vertical springs, II II, carrying oil-rubbers f f, which are arranged to rub off the oil on journal, whereby its waste is prevented.

G is a bail or brace secured to space-blocks (Z d in the head of the frame D D, and serves the purpose of support and also of raising and lowering the said head-frame. The frames D .D"' are spaced below by the means of thimble c.

a b are lugs and pivots whereby the head D D is hinged. v

y, Fig. 3, is an oil-hole to admit oil within the box formed by the frame-head D D; or it may be admitted by means of porous material at the end, as shown by the letter 9'.

The operation of all the above parts will be readily understood from the foregoing description.

Having described my invention and the means of carrying the same into effect, I desire to say that many modifications of detail may be made within wide range without 'departing from the spirit thereof.

I claim 1. The combination, in a lubricator for carboxes, consisting of the yielding lubricatingrollers, pivoted as descnibed, and adapted to be in contact with the journal-bearing for the supply of oil, of the vertical spring supports having the rubbers, also adapted to be in contact with the journal-bearing, for preventing the waste of oil, as set forth.

2. The lubricator for car-axles and the like, consisting of the carryingframe D D, horizontal frame E, pivoted as set forth, and the spring-rubbers, the former having lubricatingrollers, as set forth.

3. The combination, in a lubricator having the upright frame-head and the horizontal frame, the former having the elongated slot adapted to receive the horizontal moving bearings of the oilers, of the springs, whereby the oilrollers may approach to and recede from each other, as shown and described.

4.. A lubricator for railroad-car axles, consisting of the hinged frames having the oilers and rubbers, in combination with the bail and brace, as described.

5. A lubricator for car-axles, having the hollow head forming an oil-box, said box being provided with oilinlet apertures for the supply of oil to the rollers, whereby only sufficient lubricant is fed to the axles, and with the movable spring-operating ournalbearings for said rollers, as described.

(3. The combination, with a journal-box, of an oil-receptacle therein, and adapted to have one or more lubricating-rollers, said box being provided with controlling oil-inlet aperture, for the purpose set forth.

7. In a lubricator, one or more journaled rollers in asuitable box or device, to prevent said rollers from running in the oil outside of said box or device, the said box or device being provided with controlling oil inlet or aperture, for the purpose set forth.

8. A lubricator provided with spring-armed oil wiper or rubber, as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

ADDISON BRADFORD.
