SPECIFICATION forming part bf m1517816 Patent NO. 491,671, dated Feblualy 14a, 1593. Application filed Julyl, 1892. Serial No33|672i (No model.)

.To all whom T3 may concern:

Be it known that I, LEWIS E. ATKINSON, a citizen of the United States, residing at Bos ton, in the county of Suffolk and State of Mas sachusetts, have invented certain new and useful Improvements in AXle-Lubricators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, 1n which-e- Figure l is a central vlong gitudinal section of the hub of a vehicle-wheel having my improved aXle-lubricator applied thereto. Fig. 2 is a side elevation of my lubricator. Fig. 3 is a sectional detail ot' the hub, the lubricator being removed therefrom and the orifice leading to the aXle-bonand axle being closed..

by a screw-plug. Fig. 4 is a section on the line of Fig. 1. I

My invention relates t'o certain improvements in axle-lu-bricators, in which a lubricating compound is forced. by pressure into contact with the axle without removing the wheel therefrom, and my invention consists in certain novel features and combinations of part-s as hereinafter described and specifically .fpointed out in the claims.

In the said drawings, A represents the hub of a vehicle-wheel, B the axle, and C the axlebox, which latter is provided on its interior surface with a longitudinal groove or channel a which extends from nearly one end to the other, as shown in Fig. 1, and is open on the side next to the axle, said channel forming a chamber -for holding the lubricating `compound which is forced therein through an aperture b in the axle-box which communicateswith a short tube o extending to the outside of the hub, preferably close to and in' perature of less than 300' Fah reuheit, hence it l must be forced into the groove or chan-nel a ofl the axle-box, which is accomplished by means vof a lubrioator D consisting of a cylindrical -to bottom, s` fitted a screw-threaded presser E, which ts the thread 15 and is provided with a stem or spindle g haviilg at its outer end a milled head h, which forms a handle by which said-piessermay-be screwed down within the shell e to force the lubricating com.- pound ,down through the nipple f and tube c into the chamber a of the axle-box. Above the presser E 'is a check-nut G which also fits the interior thread 15 of the body aand is provided with a central upwardly extending tubular portion or sleeve k which encircles. the stem g and is free to move longitudinally thereon, said sleeve c being provided at its outer end with a milled head m, which forms a handle by means of which the nut ,G may be turned and jammed down onto the presser E to lock the latter iu place and prevent it fmm being moved after it has been screwed down sufficiently-to force the proper quantity of lubricating compound into the chainber a of the axle-box. The parte are then allowed to remain iu this position until a new.

suppiy or lubricating compound is required, when' the oheck-nut-G is slightly loosened and the presser E again screwed do'wu by taking hold of its head h until. the latter is brought into Contact with the head m of the checknut, which head thus serves as a stop. or gage to limit the descent of the presser' E Within the shell e, and thus regulate the quantity of lubricating compound forced into the axle-box ata single operation; the distance between the two heads h sndfm, as shown in.A

Figs. 1 and 2, being such that when the checknut- G is slightly loosened and the headJa screwed down into contact with the 4head. m,

the proper quantity of lubricating compound will have been forced from the s'hell `c into 'line cheminer a, of the axle-box, the axle being thus easily and conveniently lubricated without renmyvingthe wheel therefrom.

The luhrioetor D may be 'fillowed to remain permnnently on the hnlo A-if desired, but is preferably removed therefrom after the oomponnd has been forced into the axleliox, and after such' removal the top of the inleti tube c is tightly closed by aserevwplngp inserted therein es seen in Fig. 3, said plugl being removed and the lubricator D again applied to the hul), when e fresh supply ot' the lubricating compound is; required.

l do not confine inyeelf to the employment of my im pr llthriontorvin*conneceion with the hub oi e' vehicle Wheel, es it is Obvious that it mn'y 'ne applied equally es well to the hubs of loose pulleys and einer wheels re volving on fixed journals. Y

What I olnim es' my invention and desire to secure by Letters Patent is:- p

l. In en liXle-lnloriceiing device, the cylindrical shell or body e, screw-threaded on its interior and adapted to contain e lubricating compound, and having a suitable discharge outlet, combined with asorewthrended pressoi- E fitting the internal thread of seid shell and provided with e een trnl stem g having a, handie 7i et its outer oncLa-nd a` check-nul; G also tilting said internal thi-eed and provided with n, tubular portion or sleeve encircling the siem g of the presser and having a. handle m nt its outer end located beneath the handle h oi said presser, seid handle m forming n slop or gage to limit the descent of thc presser nlece the qnentity'o lubrieating compound forced forward at a sin operation', substantially es described.

2. ln en axle-lubricating device, the combination, with the hub and. exlebox, the latter pro ided on its interior surface with n longitud vnel groove a open to the axle space and adapted to contain e lubricating compound and connected with n tube or passage leading Y to the exterior of the hub, of e lnbricator consisting of e cylindrical. shell or body e having e nipple or nozzle adapted to be screwed into the inlet opening in the hub, seid shell e having en internal screw-thread, e. screw-threadv ed presser E Iitting seid thread, n'nd provided with n stein having n handle at its outer ena, and :L check-nut G also fitting the internal thread of the cylindrical shell and provided with e sleeve encircling'the stem of the presser and heving e handle located beneath the hanf die of, the stem of the seid nut serving to look the presser in place when forced downward, and its handle forming a stop orgnge tolimit the descent of the presser and thereby regulate the quantity of lubricating compound forced into the axle-bozt at e single operation, all constructed and operating substantially as set forth.
