snerriclirlon forming'parf IQi haar@ reiterar-0,654,665, dated my e1, 190e. aimaient-lea runt 25, 1to0.` senil No. 21.473. (Nomaden cinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Lubricators,of which the i following is a full, clear, and enact description, reference being had to the accompanying drawing, forming part of thisjspecilication.`

My invention relates to that class of lubri- 'cators which have a constant source of oilsupply un( er pressure and which are genei-, ally coupled together to make this source of bil-supply common to a number of such lubricators and which in addition have an auxiliary oil-cup for each bearing, which'caube brought into use at any time should the source of oil from the pressure-supply beat any time broken or out off;` and it has for its object the provision of such alu bricator which is both simple and cheap in construction and` eiicient in action. i 1 vThe novelty will be hereinafter more fully l set forth, and specifically pointedxout in the claims. l y i In the accompanying drawing, the ligure represents a central sectional View, in elevai tion, of a lubrioator embodying my invention.

A represents a valve-casingwith a centralchambcr a. V On the upper side of the valvechamber is an exteriorlythreaded stern b with --a central chamber 0,fromwhich an oil-exit passage d, having-a tapered upper end, eX-l tends into the chamber ci. Screwed upon the stem b is the vbaseTB of an ordinary glassbodied cylindrical oil-cup C,Witl1 `a hollow' central stem D extendingup from the base through the cap E, which is held down by a nut F, screwed upon the `upper projecting threaded end of the stem D. Within the bore a of the stem D is fitted a valve-stem G, Whose lower pointed end fits into the tapered end of the aperture b to close theisame.` H is a coiled spring around the upper part of the stem G and conined between an enlargement or collar uponsaid stem andzan adjusting cap-nut I, screwed uponthe upperend of the stem. J is a spring-held snap armor lever pivoted to a block upon the upper end of the stem for Opening the aperture d when in one position and closing it when in the other po-` fr ,sitiom All of this onstruction of the oil-cup Gand its`parts, together with the holdingspring K for the adj usting-nut, the swinging cover L for the iilling-opening in the top of the cup, and t'he oil-exits e from the base into the chamber 'c is common and well known and needs no further description here.

. Upon the under side of the valve-casing A is au interiorly-threaded projection or nipple f, into which isd'screwed the attachingstem M, by which the apparatus .is screwed to' 'the bearing to be lubricated. The stem M has a central bore g through it, with interposed circular openings h for sight feed glasses, and its upper end communicates with an opening into the chamber a.

Upon ,one side of the valve-casing A is a vsuitable means of connection to the pipe containing the constant source of oil-supply under pressure. In this instance the connecting means consist of` an eXteriorly-threaded nipple fi, having an openingj through it into the chamber a, a union-coupling 7c screwed upon said nippleland holding an exteriorly- 4threaded thimble @which is united to the oilsupply pipe (not shown) bya right-and-leftthreaded coupling m. Opposite to the aperture j and extending outward from the chamber et is a bore in a projecting exteriorlythreaded nipple n, containing a valve-stem Wit-hexterior means for operating the same for opening and closing'the aperture'j as desired, the end of the valve-stem being pointed to snuglyiiit the tapered bore of the aperture j. In this instance the Valve-stem o last re- "ferredv to has a coiled spring p around it confined ,between a -collar on the stem and an adj usting cap-nut g, screwed on'the end of the nipple and held in any of its adjusted positions by a springr of well-known construetion and similar to the spring K,"- -The'outer end of the valve-stem o is coupled to a spring snap-arm N, similar to the arm` J, for opening and closing the aperture j.

In operation the aperture 0l iskept closed to entirely shut off the supply of oil-'contained in the cup C, and the aperture j is opened to the required extent to feed the oil from the source of pressure-supply through the chamber a, thence down through the bore g and sight-feed opening 71, to the bearing to be lu- IOO Y* bricated, i Should, however, thel oil supply` -frorn the aperture j beat any time interrupted; I

fromany cause, such as a breakin the pipes or the temporary exhaustionof the sourceof oil-supply, the aperture j is at once closed and d opened' to permit oil from the cup C to befed I Vto. the 'bearing Y .until the pressure-supply is oil-cup connected to said valve-chamber and' e leading into said valve-chamber througha valve-controlled aperture, and lvalvey mech-y ,r

again brought, into action, ''Whereupon the; aperture d is again closed .and Ithe aperture j opened.

u In my construction, unlike that of others,/

which vtake the pressure-supply directly into the cup C, and thereby puta leakingior even abreaking pressure upon the cu-p -C,there'is no pressure upon the cup C, Whichrsta'ng'ds constantly as la source of auxiliary supply Whenever the pressure-sup'plyis interrupted;v
