To all whom i may @Lincei-m perforntion in the tup u onlo the journnl Be it known that I, TILLIAM T. Surfin, ot' by the compression nl' the nir between ilu? Baltimore, in the State of Maryland, hure iu- Vene certain new and useful Improvements in Lnbricators; and I do hereby deelnre Lhe following to be a full, clear, and exnt-l deseription of the invention, such as will eri-(nilo others skilled in the arb to which it nppertninsto make and use the saine.

My invention relates to au improvement in lubrieators, and more particularly to that class of lnbrientors employed in supplying n lubricant. in its nondiquid state to journals.

The object of my prfentl invention is to provide a lnhrientor which shall eeononlize grease, keep the journals constantly luhricated, and which shall he Simple und inexpensive in construction.

'With these ends in view-:ny invention cousists in certain feature.u ol' construction und combinations of parts, will be hereinafter described, and pointed out in the claim.

in the accompanying drawings, Figure l is a view of the lubrientor in position on ajournnl-box, and Fig. 2 is a View of a modified forni adapted fonnse'in connection with eerriage or wagon wheel hubs or loose pulleys.

A represents n cylindrical-shaped cup, prefernbly provided with a rounded buse, ne Shown, and terminating :it its lower end in n screw-threaded tap, a. An engulnrehnped nut-section, B, is conveniently formed be tween the screw-mp a and the bottoni ol" the cup for convenience in screwing the cup on and o thejournal-loox. The interior ol' the cup A is screw-threaded from top to bottoni, as shown at C, and a plunger, l), is provided with a male thread, d, on its edge, ndnpted to register with the thread C. the plunger i) is preferably concave, forming` a el'unnber, E. The plunger ills further providedwih a siem, e, on its upper side, nud n thumb-wheel, F, is formed on the stein l'or conveniently operating the plunger.

In operation the cup is filled with e lubricant in non-liquid forniwa lu'loricnnt eoniposed of pnrafiine and neats-foot oil, for example-and the plunger D is inserted in the The lower lnee ol' lower linee oi' the plunger und the upper `snri'nee ol' the grenen.
