AUTOMATIC LUBRICATOB.

Specification of Letters Patent.

Patented 'June s, 191.5.

Application filed February 2, 1914. Serial N o. 815,870.

cally by the starting and stopping of the engine;

A further object of my invention is to construct a lubricator provided with a double head piston, against which live steam is directed for manipulating a valve for automatically regulating the ow of the oil from the oil receptacle to the engine cylinder or other parts to be lubricated.

A further object of my invention,is to construct a lubricator which will open and permit the oil to circulate automatically with the starting of the engine, and to close automatically when the engine is stopped.

Figure l is a vertical sectional view of my improved lubricator. Fig. 2 is an enlarged* detail sectional view of the valve mechanism made use of through which the condensation is admitted into` and discharged near the bottom of the oil receptacle. lFig. 3 is a bottom plan view of the valve. Fig. et is an enlarged detail sectional view of the check valve made use of in the steam inlet pipe.

In carrying out my invention I provide a lubricator consisting of a tubular member 5, its upper end flaring outwardly forming Aa piston cylinder 6, the bottom end of the tubular member 5 being suitably threaded and seated in a liquid condenser 7 ,this condenser isprovided with a partition wall 8 having a central downwardly projecting tube 9, which extends into an oil receptacle 10. In the piston cylinder 6is located a piston head 11 to which is attached a valve `stem 12, which extends downwardly through the tubular member 5, and into a liquid condenser 7. The bottomend of said stem is provided with a valve v13 which is located in a valve casing 14 located on the top of the tube 9. On said valve stem is also located a piston head 15, which is of smaller diameter than the piston head 11, and which conforms with theradius of the interior of the tubular member 5; this piston head is separated a reasonablev distance from the piston head 11, `and the downward movement of the piston head is limited by a flange orinternal rib 16 located on the interior of the tubular member 5.

The flaring portion of the tubular member is preferably mountedas shown, and is provided with a shoulder 17, which acts as a supporting seat for a spring 1S, which encircles the valve stem 12, and contacts with the under surface of the piston head 11; the two piston heads are properly spaced apart by means of a sleeve 19 located between both `heads and encirclingv the valve stem 12. y y V On the topfof the piston cylinder 6 is i locatedv a liquid receptacle 20, the same being detachably connected as shown, 'and that portion of the bottom 21 of the receptacle which acts'as the cover for the cylinder 6 is provided with a small opening 22 through which theliquid from the receptacle 2,0 is permitted to pass into the cylinder 6, and rest upon the top of the piston 11, the purpose of which will be fully hereinafter described. To theV top of the liquidreceptacle 2O is connected a pipe 23, whichis a branch of the pipe 24 leading to the steam chest; 8l5.

this pipe vcontinuingy downwardly also leading into the piston cylinder 6 ata point above the top of the piston head 11, and is provided with a .check valve 25, vthe construction of which is clearly shownk in Fig.

4; this check valve is provided with/a spring-actuated valve head 26 normally seated in the valve seat 27 and asV the steam ypressure is admitted into the steam chest of the cylinder it also enters the'pipe 24e cone nected thereto, the vvalve is openedfand steam admitted into the cylinderv 6 above the piston head 1l. y y Y In the tubular member 5 is located a pipe connection 28, which leads to the steam dome of the locomotive and through which live steam is admitted into the tubular member 5, and condenser 7,; all condensation of the steam lodging in the condenser 7 and which condensation `is permitted to flow downwardly through the tube 9 into the oil receptacle 10 whenever the valve 13 is depressed; the normal tendency of the steamv pressure admitted-through the pipe 28 con- I nected to the steam dome of thebo'iler is to hold the valve 13 closed by means of the steam pressure against the bottom of the piston head 15.

The oil receptacle 10 is detachably connected to the liquid condenser 7 as shown, the said condenser being provided with a horizontal partition wall 29, spaced a reasonable distance above the bottom 30 forming an oil chamber 31; from this oil chamber leads an inlet pipe 32 projecting upwardly, its top being a short distance from the bottom of the horizontal wall 8, and through which the oil located in the receptacle l0 isted from the receptacle into the chamber 31 as the condensation or water fed from the condenser 7 enters into and near the bottom of the receptacle 10, which tendency is to force the oil upwardly. The oil which feeds into the chamber 3l is then permitted to pass through the jets 32 into the sight feeds 83, and then pass outwardly through the openings Self into the proper pipe connections and is ted drop by drop from this point to the engine steam chest and cylinder or any other location to which the pipe is connected.

rThe feed is regulated by means of the needle valves 35, and the same are regulated to the required amount of oil to be fed before the locomotive leaves the round-house, and in order to prevent tampering with the reg ulation, a hood or cover 36 is placed over the same and secured by an ordinary lock 37.

The operation of my invention is as follows: rlhe receptacle 10 is lilled with oil, either by a separate inlet, or by detaching the same from the condenser 7. Liquid is admitted into the receptacle 20 and the valve 13 is held normally closed by means of the spring 18. Steam is admitted into the tubular member 5 through the pipe 28 which is connected to the steam dome of the boiler, the pressure of said steam assisting in normally holding the valve closed, and the condenser 7 is supplied with water by the condensation of the steam. When the locomotive is operated and steam admitted into the steam chest for operating the engine; steam is lilrewise admitted through the pipe connection 24 attached to the steam chest into the liouid receptacle 20, .and above the .piston il, the radius of the piston 11 being greater than the piston l5, the steam pressure admitted above the piston l1 has a tendency to press the same downwardly opening the valve 13 allowing the water of condensation to pass from the condenser 7 down into and near the bottom of the oil receptacle 10, and by the feeding of the water below the oil line will force the oil upwardly and permit it to iiow downwardly through the tube 32 into the chamber 31, and then out through the sight feeds 33 into the tube connection, which leads to the cylinder or steam chest. Whenever Vthe steam is cut oil' from the lsteam chest of the engine, the pressure of the steam in the tubular member 5, below the piston head l5 has a tendency to close the valve to check the flow of water, and also the feed of the oil; this closing teature is then gradually and slowly closed by means of the liquid located in the piston cylinder above the piston head ll, as the upward pressure of the piston head ll forces the liquid baclr into the receptacle 20 through the aperture or opening 22. rl`his gradual flow of the liquid from the piston cylinder back to the liquid receptacle acts f as a cushion, permitting the valve to close gradually and slowly while the locomotive is drifting and the steam from the steam chest cut otll so that oil is continuously and slowly fed Vinto the cylinder during that period. This is one of the essential features and objects of my invention: to supply il. tc the cylinder while the engine is in operation, and also while the locomotive is drifting, but to automatically stop the flow of oil when the locomotive is at a stand still.

Having fully described my invention what l claim is:

l. ln a condensation displacement lubricator, comprising a lubricant receptacle, a condenser mounted above same, a piston chamber mounted above the condenser, a plurality of pistons mounted on a piston rod operated in said piston chamber a piston rod extending into the condenser and forming a valve stem; a passage way connecting the lubricant receptacle and condenser, a valve located in said passage way and mounted on the valve stem for controlling the iiow ot the water from the condenser, a steam connection to the condenser and piston chamber, and an outlet from the lubricator, substantially as specified.
