iMPRVEMENT IN' LUBRICATING DEVljCES FOR STEAM-ENGINES Specification l'orming part of Letters Patent rim-190,722, dated May 15, 1877; application'liled.

' I October 3, 1876.

To all, whom t may concern Be it' known that I, WILLiAMMosEs, of the city of Buialo, in the county of Erie and State of NewYork, have invented certain new and useful Improvements in Lubricating De- `vicesfor Steam-Engines, which improvements are fully set forth in the followingspecitication, reference being had to the' accompany ing drawings.

My invention yrelates to a device designed for supplying the lubricating material to the cylinder or other parts ot' a steam engine, pumpor similar mechanism, in a regular and uniform manner, while'permitting the quantity of the lubricating material-so supplied to be readily regulated, as may be required.

The' nature of my invention/Will be fully n n- 'derstood from the following description.

' In the accompanying drawings, consisting of two sheets, Figure l is a vertical section of my improved lubricating device. Fig. 2`is a top-plan 'view thereof. Fig. 3 is a vertical section at right angles to Fig. 1. FigA is a horiaontal section in line Fig. 3.

Like letters of reference refer to like parts in each of Vthe figures.

A represents the cylindrical oil-receptacle,

` preferably made of glass, and provided with a metallic bottom, A1, adapted to be secured to any suitable support, aud a metallic top or cover, A2, both the top and bottom being prolink, Dl, secured to the cover A2, while the` long arm ofthe lever D is connected by a rbd,

LIP, with any suitable moving part of the engine or pump to which the lubricator is applied, so as to be actuated when the engine or pump is in motion. e is the suction-valve, arranged in a chamber, E, opening-into the receptacle A, and communicating with the footy of the pump-barrel B. j' is the pressurevalve, arrangedin a chamber, F, communicating with the foot of the pump barrel, and

opening into the discharge-pipe Gr, which dives and penetrates the bottom A1 of the oil-receptacle. The pump-barrel B and chambers E and F are preferably cast in one piece with the bottom A1 ,of the oil-receptacle.

The main portion of the screwed into the bottom of the oil-receptacle,

.is made of any suitable length, as circumstances may require, and provided near the steam-cylinder, or other part to which the oil is to be supplied, with a check-valve, g, of any suitable construction.

H represents the return-pipe, connecting with the discharge-pipe G at a short distance from the oil-receptacle, and opening into the latter, as clearly shown in Figs. 3 and.4. I is a cock or valve, arranged in the return-pipe H, for regulating the flow of the oil through thesame. lis an opening formed in the cover A2 for introducing the oil, and L a cylindrical strainer, arranged under the opening l, for catching any coarse impurities which may be contained in the oil.

My improved lubricating device being'connected with a steam-engine or pump, as hereinbefore described, a uniform reciprocating motion is imparted to the plunger C. When the valve I in the returnfpipe H is entirely closed, the full quantity of oil displaced by the plunger C during its downward stroke is forced into the cylinder, or other part to which the dischargepipe G is connected. Upon opening the -valve I to a greater or less extent,l a portion of charge-pipe Gr by the plunger C isrpermitted to return to the receptacle A by. the pipe H, the amount so returned being proportionate to the extent to which the valve I has been opened, and the pressure of the steam opposed to the discharge of the oil from the pipe G. When the valve I is entirely opened all of the oil forced into the discharge-pipe G is returned through the pipe H into the re-V ceptacle A. From seen that by opening the valve I to a greater or less extent, the amount of oil discharged from the pipeGr at each stroke of the plunger can be regulaged with great nicety, thus rendering the lubrication regular, and at the saine time adjustable` to the req' enreats ofeach discharge-pipe, y

the oil forced into the disthe foregoing it will bel particular case. It is evident that motion enay be applied to the plunger U in any desired and suitable manner.

Having thus fully described my invention, ,'Whait I claim as new, vand desire to secure by Letters Patent, is y A l. The combination, with the oil-receptacle and discharge-pipe of a lubricatingpump, of .a return-pipe-provided with a. suitable cock or val-ve for reguieting the amount of oil ejected from the dischergepipe by the action of the pump, substantially as hereinbefore set forth. 2n- 'he combination, with the oil-receptacle A and pump B C, arranged therein, of the discharge-pipe G and return-pipe H, provided with regulating-valve I, arranged as and for the purpose hereinbefore set forth.

yEF, the parte being' secured together by bolts a, as and for the purpose hereinbefore set forth. 4.' The combination, with the oil-vessel A A1 A, of the force-pump B O, discharge-pipe .G, return-pipe H, valve lever D, and actuating rod D2, substantially as and for the purpose hereinbefore set forth.

WILLIAM MOSES.
