IMPROVED LUBnIcA-rme nnvrgs.

Be it known that I, THOMAS S. BROWN, of Poughkeepsie, in the county .of Dutchess, and State of New York, have invented a new and improved Self-oiling Device for crank-pins and other journals of machinery; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the sari 1e, reference being had to the accompanying drawings, forming Part of this specification, in which-- Figure 1 is a side sectional view of myfinventiou' taken in the line :r' x, fig. 2.

Figure 2, a front sectional view of the same, taken .in the line y y, fig. 1.

Figure 3, an under view of an inverted-plan of the stopper of the oilfountain.

Similar letters of reference indicate like parts.

The object of this invention is to obtain aself-oiling device for crank-pins and other journals of machinery,

which have either a rotary or reciprocating motion, to keep the oil in the fountainiu a suflicien't state ofagitation to cause the same to be fed to the journal in requisite quantity to insure perfect lubrication. I

The accompanying drawings represent the invention applied to a crank-pin or crank journal, which is designated by A, the pitman or'conne'cting-rod being designated by B, and Grepres'enting the hearing which encompasses the journal A. The bearing 0 is composed of ."two parts, a b, the part a having a circumferential projection, c, at its centre, grooved, as shown at d, to receive th'e prongs e e of the pitman or connecting-rod B lhe other part, 6:, of the bearing is cast or provided with lugs or ears,through which the prongs e e of the pitman 'or connecting-rod pass, saidiprongslhaving screw-threads cut on "them to receive nuts, g, a plate, It, being fitted on the prongs-at the outer sides of the nuts and n'u-tsi screwed on'the prongs at the outer side of the plate Inns shown clearly in fig. 1. 7 By this arrangement-it'will be seen thatv the parts ob of the hearing are firmly secured to: the journal A, and the 'pit'mansecured to the hearing. The part b of the bearing is cast or otherwise provided with anoil-chamber, D, having a screw-plug or stopper, E, in its upper vend, and F is a tube' :oxtending up within theoil-chamber, and communicating with a passage, 0, which extends downward'through the part bof the bearing, so as to convey oil from the chamber D down to the journal A, as clearly shown in fig. 1. The under surfacev of the plug or stopper E hash groove, j, made centrally across it, with a recess or cavity, k, at its centre, which recess or cavity is "dircctly over the tube E when the plug or stopper E is screwed into the oil-chamber D. The-charnb er is supplied with oil or other suitable lubricating material, and-:th e oil in said chamber, as tho ,crankspin or journal, 1A, rotatesbr otherwise moves will be agitated and thrown against the lower cnd of the plug or stopper E, and'the groovej will convey the oil over the tube F, the former dropping into the latter which'conveys itto the'journal A.

This invention is applicable to all journals of machinery whichhave inotion sufiicient to cause the oil to be thrown agninstor. brought in contact with the lower end of the plug or stopper over .the tube F. The operation is sure and cfiicient. There can be no over supply or waste of oil, and theperfect lubrication of the journal is rendered certain as long as any-oil is contained in the chamber D. I

I claim as new, and desire to secure by Letters Patentchamber D, in the part b of the bearing G, through which extends the-tube F, communicating with the passage 0, in combination with the plug E and journal A, arranged and operating substantially as herein described and for the purpose s )QOlllOLl- I further claim the plug or stopper E of the oil-chamber D, grooved at its under side, in combination with the tube F and passage 0 in the bearing, substantially as and for the purpose specified.

THOS. S. BROWN.
