CAR-AXLE LUBRICATO R.

SPECIFICATION formingpart of Letters Patent No, 280,587, dated July 3, 1883. Application filed Jun 24, 1882. (No model.)

To all whom it may concern: I

Be it known that we, Ansesrus B. DAVIS and NATHAN H. DAVIS, both citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Lubricators, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a top view of the lubricator embodying our invention. Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a horizontal section thereof. Fig. 4 is a transverse vertical section thereof. Fig. 5 is a view of a detached portion. Fig. 6 'is a horizontal section of a modification of Fig. 5.

Similar letters of reference indicate corresponding parts in the several figures.

Our invention consists of a lubricator in which the lubricant is fed or supplied to the journal or axle by gravity, thus effectually and continually accomplishing the lubrication.

It also consists of the lid or cover of the journal-box, peculiarly constructed, whereby it firmly retains its position and may be conveniently opened.

It further consists of means for lubricating the end of a journal or axle.

It also consists of a guard. for the lid.

Referring to the drawings, A represents a journal or axle of usual construction, and B the box thereof. On opposite sides of the box are diagonally arranged tubes or chutes G, which extend from the exterior of said box to the interior thereof, communicating with the latter by means of oblique openings a a in the sides thereof, said chutes being cast withor secured to said sides, and are the recipients of the lubricating material D, which may be of the form of blocks generally known as hard grease. The space betweenthe journal or axle and bottom of the box is packed with wool, cotton, or other suitable substance, and also supplied with lubricant, said space being in communication with side spaces of the box, and thus withthe chutes O, as morereadily seen in Fig. 4. It will be seen-that when the lubricant is placed in the chutes C it bears against the journal or axle and remains thereagainst by gravity, so that. it is continuously in con tact with said j ournal and axle, and thus effect ually lubricates the same, fresh surfaces of the lubricant being presented as it is worn off by the rotation of the journal or axle. Some of the lubricant removed from the blocks is carried around by the journal or axle and directed into the packed space below the same, thus feeding said space and continually lubricating the journal or axle from below. Fresh blocks may be placed in the chutes as required, it being noticed that the expenditure of the lubricant is gradual, and leakage thereof is avoided.

E represents the lid or cover of the box, which is hinged to the front thereof, the grid geons or journals of the lid entering avertical slot, 1), in the bearing or cheek-piece 0 of the box, whereby the lid may be raised from its bearing. The lid is of angular or bent form, the upper part being horizontal and adapted to rest on the top of the box. It will be seen that when the lid is raisedit is lifted from the top of the box, and may thus be swung outwardly, and thereby opened, the operation being accomplished in an easy and convenient manner. \Vhen the lid is to be restored or closed, it is raised above the top of the box, and then permitted to lower thereon, whereby it remains firmly in position, fully closing the front opening of the box. The sides of the lid are extended laterally, forming wings E, which project over the upper or outer ends of the chutes 0, whereby provision is made for covering and uncovering said chutes and dispensing with separate lids.

F represents a piece or brass, which is fittedtvertically in the box between the front wall thereof and the adjacent end of the journal or axle, so that said end may bear against said piece F. In order to lubricate the journal or axle at the end just stated, the inner face I of the piece F is grooved from the side to the center, forming a duct, (1, to which oil or lubricant material may be admitted through the front opening of the box or side chutes, C, the lubricant thus reaching the end of the journal or axle.

In Fig. 6 the duct d extends through the piece F and. communicates with a space in the I box, said duct and chamber being suitably packed, the lubricant readily reaching the journal or axle through said duct.

Projecting forwardly from the journal-box IOO are guards (l, whieh are east; with the box, and so disposed that they inelose the sides of the lid, whereby, should the box he struel; in the direction of the sides of the lid, the blow will he received by the guards, thus preventing injnry or breakage of the lid or ot the hinge thereof.

Having thus deserihed our invention, what we claim as new. and desire to seeure hy Let ters Patent, is-

l. A ear-axle box provided at its outer end with (.heek-pieee e, having Ytll'lt'fll slot I), in

I eoinhination with cover E, having a gudgeon which sets in. said slett, said cover resting at its upper end on the top of the box, as set forth. 2. Thehox provided. with a chute at-itsside, in ('mnhination with the lid 01- cover having-a lateral extension, snhstantially as and for the purpose set forth.
