IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 40,433, dated October 27, 1863; antecated October 10, 1863;

reissue No. 5,737, dated January 20, 1874; application filed November 29, 1573.

To all whom it may concern:

Be it known that JOHN R. SEEs, of the city of Philadelphia, in the State of Pennsylvania, has invented a new and Improved Lubricator for Locomotive and Steam-Engines; and the following is hereby declared to be a full, clear, and exact description of the same, reference being had to the accompanying drawings forming a part ot' this specification, said drawing representing' a central vertical section ofthe lubricator.

The invention may be generally stated as follows: It consists in combining within the cup ot' a lubricator for steam-engines a supply-tube and a regulating-valve, adapted to be operated by differences in the pressure of steam iu the valve-chest or other part to which said lubricator is applied, to admit steam through the tube into the lubricator, and to permit the passage from the lubricator through the tube of the oil or grease displaced bythe condensation ot' said steam, as hereinafter described. It fun ther consists in uniting the top and the base ofthe lubricator, by means of an interior central. tube constitutingat the sam ev ti me the only channel by which the lubricantl can be conveyed from the cup to the parts requiring lubrication, as hereinafter described. It further consists in combining with the oil-cup or ves sel. that contains the lubricating material, an atmospheric valve or air-vent,operating at the proper time to admit air from the outside to the interior of said cup.

The accompanying drawing, which willnow he referred to, is an embodiment of all the scv eral features of the above invention above stated.

A I5 O is thecup, composed of a thick cylinder, D, of glass, constituting the body, and a base, A, and top O ofbrass, but it maybe made entirely of brass. The parts A, B, and O are held together by an interior connection entirely within the body ofthe reservoir, here representv ed as consisting of a central tube, D, and a nut, a, the central tube screwing tightly into a hole in the bottom A, and passing through a fixed bridge, b, formed across the top C, and the nut a being screwed onto the tube above the bridge b, and brought down tight upon the bridge. A vulcanized india-rubber or other soft packing, c, is used between A, O, and B. The top O is fitted with a movable cap, E, to provide for the filling of the cup with oil or tallow. F is a valve on a stem, d, passing through the tube D, and vfitted to a conical seat in the bottom A of the cup, and closing in an upward dircctioi'l. The stem terminates in a head, G, resting normally on the top of the tube D. 'The stem d is made in two pieces, screwed together at c, to provide for its being lengthened or shortened, and thereby regulating the amount of movement of the valve. The valve F lits perfectly tight to its seat when closed, but the end of the tube D, on which head G rests, is notched, as shown at fj', so that the said tube at that point is liever perfectly closed, the oli'- iice ot said head G being to serve as a stop to regulate the Opening movement of the valve F, and so prevent the oil or tallow from running into the tube D, as it is being poured into the cup. Tere it notrequired to serve the latter purpose, the upper part ofthe stem might simpl y be furnished with lugs, or have a pin inserted transversely through it, as a substitute for the head GY. H is a valve, which has been above refe red to as the atmospheric valve or airvent, fitted into the cap E, and closing with an. upward movement. This valve has a stop, g, at the top of its stem, to limit its opening movement, but the top ofthe cap is so notched, ex.4 ternally, as shown at b b, that the said stop does not close the opening therein when the valve drops. I is a cock in the bottom of the cup, for emptying it. J is a socket, which has screwed into it a nozzle, i, provided on the bot-4 tom A ofthe cup, and which is itself provided with. a nozzle, j, to be screwed into a tapped hole in the steam-chest, orother part requiring lubrication.

To set the cup ineperation, when used for cylinders or steam-chests, it is flledvwith oil or tallow upto the level of the top of the tube D. While the steam.cl.1est is open to the boiler and filled with steam, the pressure ot' the steam keeps the valve F closed, but the valve H is kept open by the pressure of the atmosphere, aided by its own weight.

Vhencvcr, in the ruiming of the engine, the

Ainto the feed-openings in, the tube l).

steam is shut ott' from the steam-chest, the valve F drops by the reason ot' its own Weight and the Weight of the stem d. \Vhen steam is again admit-ted to the steam-chest it closes the valve F again, but before it can close the valve some steam escapes through .the tube D into the upper part ofthe cup, and closes the valve Il, which prevents its escape from the cup. rlhis steam being sluit into the cup by the closing ofthe valve soon condenses, and the irater of condensation sinks below thegrease, which floats on its surface, and rises above the level ot' the tube D, down which it ows by gravitation, remaining in the said tube or thc passage in the bottom Abeloxv it, until the steam is again shut ott', when the valve F be ing again opened the grease runs into the steam-chest. The valve H. opens when the steam has been condensed or vpartially oordensed -in the upper part ofthe cup, and so adv mits the pressure of the atmosphere upon the grease at all times, except when the steam isr uneondensed in the cup, it bein desirable to catch o1' trap all the steam admitted to the cup, as it is by the water resulting from the condensation ot' such steam that the grease is raised above the level of, and caused to oW If in the ordinary ruiming ot' the engine the steam is not shut oft as often as it is desirable to lubrieate the valve, the lubrication may be effected by simply shutting oit' and letting on the steam again quickly.

lhe quantity of oil supplied at at a time is regulated by the quantity ot' steam admitted tothe cup, and this is regulated by the amount ot' movement permitted to the valve F by the djustment ot' the stem at e, a longer movement not Vallowing the valve F to close soquickly when steam is admitted to the steam-chest,

and so allowing` more steam to pass into the cup, and a shorter movement allowing the ysaid valve to close more quickly, and less steam to pass into the cup. Ilhis operation continues so long as any grease remains in the cup, the grease iloating on the top of the Water as the cup ills up with the latter. YVhen all the grease is out, which may be easily seen when the bodyT B of the cup is made of glass, the Water is drawn o by opening the cock I, and the cup is refilled with grease by taking oft' the cap E, and pouring in the lubricant, and the lnbricator can be applied to any part, such as a steam-chest, cylinder, crank-pin, or connecting-rod requiring to be lubricated.

The independent screw-socket J enables the cup to be adapted to any part requiring lubrication. The screw-thread on the nozzlej ot' this socket need not be cut until the cup is to be applied, when the socket may be chucked in a lathe, and the said thread be cut to t any hole that may be tapped in the steam-chest or other part for its reception, and the cup can thus be tted in place Without putting it in a lathe and running the risk of breaking the glass, or otherwise injuring or marring it.

W'hat is claimed as the invention of the said JOHN It. Suns is as follows:

l. In a lubricator for steam-engines, the cornbination, substantially as described, ot a supply or feed tube and aregulating-valve, adapted to be operated by differences in steam-pressure, to admit steam through the tube into the lubricator, and to permit the passage from the lubricator through the same tube of the oil or' grease displaced bythe condensation of said steam.

2. The central feed or supply tube, fast to and Vextending from the bottom, and united with the top of the lubricator by an interior connection, substantially as shown and described.

A lubricating cup or vessel, composed of a glass cylinder or body, a metallicJ top and bottom, and a central tube extending between and uniting said bottom and top, and oonstituting at the same time the sole channel through Which the lubricant is fed from the cup, substantially as shown and described.

Il. The combination of the feed or supply tube, the regulating valve and its stem, capable of being elongated or shortened to allow a greater or less movement to the valve, substantially as and for the purposes shown and set forth.

5. The combination, with the oil-cup or vessel, of theatmosplieric valve or air-vent, operating at the proper time to admit air into the cup, substantially in the manner shown and described.

In testimony whereof, We have hereunto signed our name in the presence of'two subscribing Witnesses.
