To all whom 21617111 (30711.3()?73.

is it known that-1.1., ALBERT G. ELVIN, of Scranton in the county of Litdiiitv'iz'tllfllfi and State of Pennsylvania, h ve invented a certain new and usefui improvement in Int rieating Devices, t which improvement the following is a specification.

This invention relates to lubricators for -regulate the application of the pressure of the lubricant feed and other objects.

The improvement claimed. is hereinafter fully set forth.

In the accompanying irawings, Figure l is a partial transverse cross-section of a locomotive-axle box, showing the application of my invention to the journal ot' a locomotive-axle. Fig. 2 is a section of all the parts, except the Fig. 3

ments, coi'istituting; the principal features of my invention. Fig. e illustrates a substitute method of constructing the concave upper side of the case. Fig. 5 illustrates the form or configuration of a piece of solid lnbricat' iug material adapted to be used in con ncction with my device.

In the illustrations the of my device is such as is suitable to locomotive axles or shafts; but it is evident that the top may be plain or. convexed or any other suitable form for surfaces differennfrom that of journals or axles.

My invention is herein exemplified as applied in connect-ion with the journal 1 of a Locomotive-axle, on which is fitted a. journalbox 2, having" the usual brass bearing 3.and lubricantcellar at, the in brican -cellar being held in place by means of 5011 the cellar i coinciding; with lugs lies the journal-box 2 and a suitable rod 7 passing through eyes 8 of the said lugs. ltwill be understood that the cellar i is an element in the journal-boxes new in use, in which cotton-waste soaked with lubricatingnoil is usunilj placed for the purpose of lubrication of the axis. The journalthe same may be dispensed with altogether and the top constructed with wooden strips 12 12, wcdneshaped in CiOSS-Hl'l'llflll and set with their edges downward, the object of the strips being tohold the lubricant mass 13 in integral form until it is used up. 'lllielubricant 13 is pressed against the screen 11 by means of a sliding bottom 14, which exactly fits in tothe box or case 15 and is constrained upward by means of a conical spiral spring 16, having itsapex resting on the bottom of the cellar and its upper coilsimpinging on the sliding bottom 14. of the case 15 aforesaid. In the specific embodiment of my invention shown in the drawings a pcglS is secured to one end of the sliding bottom 14 and extends through a slot 19 in one end thereof. \Vhen the'case is placed within the cellar, the said slot in registers or coincides with a similar cutaway poi-lion 20 in the corresponding wall of the collar 4, thus furnishing an indicator for theattendant to see how far the lubricant has worn away without opening'the box. 1

In using the device the case 15 is placed against the journal to be lubricated, with the screen 1.1 in contact with the moving surface.

The solid lubricant being placed within the case is compressed against the opposite side of'the screen 11 by means of the spring 1.6 being constrained against the movable bottom 14 of the case.' .By placing the lubricantcase on the under side of theaxle the lubricant is supported and pressed into engagement with the axle by the coiled spring, and as it wears away and gradually becomes lighter the coiled spring becomes elongated and being under less strain is of course weaker, and in this way the lubricant is compressed equally hard against the axle whether IOC .proximately' corresponding the casebe full or partially empty, the ten sion of the spring increasing or decreasing in direct proportion with the weight of the mass supported. Where the strips 12 are substituted for the wire-cloth, the pressure of the spring underneath forces the lubricant between the strips, and they serve to hold it from breaking or rolling up into separate masses or, in other words, preserve the integrity ofthe whole. By constructing .the strips 'wedge'shaped, as shown, -I find that no difficulty is experienced in having the solid lubricant pressed up between them in engagement with the axle by the spring an slidable bottom above described.

I claim as myinventiou and desire to secure by Letters Patent -1. Theherein-describedlubricating device comprisingin combination an axle box cellar, a lubricant-case fitting therein and provided with a concave open-work top, a movable bottom in said case, a spring arranged to constrain said movable bottom toward the axle, and a mass of solid lubricant resting upon saidmovable bottom.

2. A lubricating'device of the kind described, comprising an axle-box cellar, a inbrican t-case 'having'a concave side adjoining the journal-surface, a wire-screen lining for said concave side, a movable part fitting the interior of said case, a lubricant interposed between said screen and movable part, and' a spring arranged to constrain said movable part toward the screen.

3. In an axle-lnbricator of the kind described, in combination with the lubricantcellar, a lubricant-containin'g case of an aparea inserted therein, a screen-covering closing the .top of said case and arranged to lie in contact with the axle to be lubricated, a sliding bottom within said case, a spring impinging thereon and arranged to constrain it in the direction *0f the screen aforesaid, the said case being adapted to contain a mass of solid lubricant between said screen and movable bottom,sub-- stantially as and for. the purpose specified.

4. In an axle-lubricntor of the kind described, the combination of a lubricant-cellar, a lubricant-case adapted to hold a mass of solid lubricant, a movable bottom in said case,- a spring adapted to constrain said bottom against a mass of lubricant within the case, and indicating means, connected to the movable bottom, whereby the attendant may see how far the lubricant has worn away without opening the box.

- 5. ,In an axle-lubricator of the kind described, the combination of a. 1nbricant-cellar, a lubricant-case, amass of solid lubricant therein, a movable bottom in said case, a

spring adapted to constrain said bottom against the mass of lubricant within the case, and a pin or projecting part on said movable bottom extending out through the lubricantcellar whereby the attendant may see how far the lubricant has worn away without opening the box.

6. In an aXle-lnbricator of the kind described, the combination of a lubricant-ceilar, a lubricant-case, a mass of solid lnbricant therein, a movable bottomin said case, a spring adapted to constrain said-bottom against the mass oflubricant within the case, and a pin or projecting part on said movable bottom extending out through thelnbricantcase and through a wall ofthe lubricant-cellar, whereby the attendant may see how far the lubricant has worn away without opening the box. 1

7. In an axle-lubricator of the kind described,thecombination ot' a lubricant-case,

a mass of solid lubricant therein, a movable bottom in said case, a spring adaptedto c'onhaving an opening in one of its walls through which the position of the movable bottom.

may be seen by the attendant.

8. In combination with the lubricant-cellar of an axle-box, a lubricant-case, a mass of solid lubricant therein, a movable bottom in said case, a spring arranged to constrain said bottom against the mass of lubricant within the case, a pin or projecting part on said movable bottom extending out through slots in' the side of the case and a wall of the cellar aforesaid whereby the position of the said and the interior of said case adapted to contain a mass of solid lubricant, a spring arranged between the slidable. bottom atoresaid and the bottom of the collar and adapted to constrain the contents ofth'e case against the screen aforesaid, a pin or projection on said slidable bottom extending through an opening in a wall of the cellar aforesaid'fo'r the ALBERT e'nnvm.
