SPECIFICATION forming part of Letters Patent No. 648,821, dated 1,

. Application filed September 8,1899. Serial No. 729,832. No modelh To 0.5L 071 0111, it may concerni- Be it known that I, HARRY ROBERT VHITE, of-Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Lubricant-Feed, of which the tion.

The object of the invention is to provide a new and improved lubricant-feed, more especially designed for use on locomotive-engines and other engines and machines and arranged to automatically feed measured quantities of the lubricant at regular intervals to the steam- The invention consis'tsof novlfat u res an' parts and combinations of the same, as wi 1 A practical embodimentof my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corre sponding parts in all the views. v

v Figure 1 is a side elevation of the improvement as applied to a locomotive-engine. Fig. 2 isan enlarged transverse section of the improvement on the line 2 2 inFig. 1. Fig 3 is a similar View of the same with parts in a different positiornand Fig. vtis a sectional plan view of the carrier-valve on the line 4 4 body A in the form-of a plug, and,.as shown in Fig. 1, is attached to steam-chest B, an oilpipe 0 discharging oil and steam under pressure into a'receiving-chamber D, formed in the bodyA, it being undcrstoodthat the oil-' pipe is also connected with the usual oil and steam supply located in the cab of 'the loco motive and of the usual construction. "'--'.l"he..

the lower end of a cylinder E, formedinfthe body A, -and closed at the topbyfa-capAQ.- forming part of the body A; In the cylinder E is mounted to reciprocate a piston F, nor mally in a lowermost position and adapted. to be forced upward .by the steam entering the receiving-chamber D audpressing against the under side of the piston, so that the lat-' ter moves to the position shown in Fig. 3.

ends of. the cylinder E are connected hyaport (1 in the side wall ofthecylinder to .allow thesteain to pass from the lower end of .the cylinder by way of the port 1.! into the upper end of the cylinder to exert erj ualizingpressure on the top t-hereof,'so that the pisa and opens a branch port Z1, leading fromthe inside of the cylinder to the'port (1 directly above the piston when the latter is in a low ermo st position, asshown inl 'ig. 2.

" Now the steam is cut off from the'up'periend of the c; illld6lE,3,uu that portion of the steam entrapped in this end of the cylinderg'radually condenses, and as soon as this has taken place the pressure of the steam in the receiving-chamber and the lower end of the cylinder is again sufficient to move the piston l" to its previous position (shown in Fig. 3) and to open the lower ud of the poi-m, so that the steam under pressure can again .pass to the upper end of the cylinderE to equalize the pressure on the piston'and to cause the same to again descend, as previously ex-- plained. The water of cb'ndensation in the 'upper end of the cylinder can readily flow through the branch port binto the port a and from'the latter through the lower end of the cylinder E into the receiving-chamber D and pass with the oil to theobject to be lubricated, as hereinafter more fully explained.

From. the'lower end of the piston F extends 'ashort piston-rod F,'which supportsa carrier-valve G, adapted to receive a measured quantity of oilfrom the receivingchamber D, I

to hold the same in a horelI for the time be-" mg, and to finally deliver the same to thedelivery-chamber I, openingxinto the. steamchest or, other part to be lubricated and COlli ectedby'the bore II with the reeeiving-cham- {her D.- The carrier valve G consists, essemt jtially, of two valves G" G connected with each other by a stem G formed through part of its length with recesses or side chambers G? (see Figs.' 2, 3, and 4) to receive and conj tain a measured quantity of the oil. The valves G G are adapted to be seated on'valveseats ll I1 formed at the upper and lower ends of the bore ll the stem G lie n-n' of such -.valves have to move a distance before the chambers G connect with the receiving-chainlength that when one valve is seated on its seat the-other valve is a distance E its seat, as W111 be readily understood by reference to- F igs. 2 and 3, and the chambers G4 terminate such a distance from the valves G. Githfat the her D or the delivery-chamber I.

When the piston F'is in -a lowermost position, the valve G is onits seat H, and when the piston F is moved upward, as previously 1 explained, then the valve G moves to its seat ber D, so that the oil can pa.

, chambers G to fill the same.

11*, while the valve G moves'oft its seat H,

1 nd the upper ends of the chambers Gr con-' 1 ect with the lower end of the receiving-chamfrom the re: ceivingchamber into the sa d valve stem time'ithe pressure on the piston F has been equali zed,.so that the pistou'descends and carries with it the carrier-valve G, whereby the upper end of the be e-H is closed before the lower end of the said bore is opened into the delivery-chamber I to prevent communication between the delivery-chamber and the above-described operation is repeated-that is, the oil in the receiving-chamber can pass into the chambers G and be then transferred to the delivery-chamber I, as abo've explained,

on the nextdownward movement of the pis- :on F. I 1

In constructing the carrier-valve G and the piston F, I prefer to form the valve G on the lower endyof the piston-rod F, as indicated in Figs-(*2 and 3, and the stem G? is provided at its upper end with a pin G, extending 7 through the piston and its piston-rod, to receive a nut G, abutting against the top oft'he [)lS'iSODy tO fasten the latter and the carrier-valve together. I do not limit myself to this particular construction of the piston and carrier-valve, as it is evident that thesame' maybe var ed; and I also" do not'li'm it myself to the application of the arrangement for the particular purpose mentioned, as the device may be used for various other purposes.
