LUBRICATOR FOR STEAM MACHINERY.

SPECIFICATION forming part of Letters Patent No. 366,714, dated July 19, 1.887.

Application tiled April i6, 1887. Serial No. 235,037. (No model.)

To (all whom it may concern:

Be it known that I, 'GEORGE Z. CLARK, of Topeka, inthe county of Shawnee and Si ate of Kansas, have invented certain new and useful Improvements in Lubricators for Steam Machinery, of which the following is a specification, reference being had to the accompanying drawings, illustrating my improvements, in which- Figure l is a vertical ccntralsectional view of my improved device, and Fig. 2 is a similar view showing a formal modification.

The object of my invention is to provide a simple, reliable, economical lubricator, to be operated by the use otsteam, and which may be attached to a steam-cylinder or other parts of steam machinery requiring internal lubrication.

Referring to the letters upon the drawings, A designates an oil-cup, open and internally screw-threaded at both ends.

I3 designates a cock or faucet, of ordinary character, lfor draining off the water of con densation.

O designates a cross-piece or guide for one end of the oil-tube D, supported in the screwthreaded opening X, to hold the tube in ils place.

E designates a cap, which screws over the top of the oil-cup, fitting steam-tight. There is a screw-threaded opening through this cap, into which fits the pointed screw-pin F, the point of the pin entering an opening in the upper end ot' the oil-tube D. This oil tube has an enlarged end or collar, L, at the bottom, having its seat made tight with a ground joint at M, in the ordinary way.

G designatesanut, which screws down upon the top ol the'cap E, and lits tightly around the smooth partof the pin F.

II is a plug or stopper for the lower end of the oil-cup, which sc'rewsinto it, as illustrated. This plug is externally screw-threaded at I on its lower end for the purpose of attaching the lubrieator to a steam-cylinder or other part to be internally lubricated.' It is also internally screw-threaded to receive the nut K. The oil-tube being inserted from the bottom in place, the nut K is screwed up, so as to press the enlarged end of the tube irmly and steamtight against its seat at M, so that the opening through the nut will form a continuation oit'the oil-tube. To supply the cup with oil, the top cap, E, holding the pin, should be unscrewed, so as to permit oil to be poured in at the opening X and partly till the oil-cup, as indicated. rIhen the cap E should be screwed down, and the pin F should be adjusted to admit more or less oil into the tube D, according to the amount ot lubrication desired. rlhcn, when steam is on, it will enter through the nut K, through the tube D, and pass into the upper part of the oil-cup, where it will condense, and the water ot condensation will settle to the bottom of the cup, raising the oil to the top, where it will overflow around the point of the pin into the oil tube and drip down through it to t-he interior of any machinery to which the lubricator may be attached.

In Fig. 2, where a modification of my lubricator is shown, the plug H is internally screwthreaded at its upper end at N, and a steamtight joint is formed at O, the position of the enlarged end ofthe oil-tube being reversed, so that it will lit down upon the seat at O, as shown. The plug II is internally screwthreaded at its upper end to receive the nut Q, which forces the enlarged end L of the tube down on its seat. This is a formal change, in which I also use a nut with a hole through it for forcing the tubeto place upon its seat.

I am aware that it is not new to lubricate machinery internally by raising oil and dripping it through the process of condensing steam within an oil-receptacle, and I do not claim that, but

Vhat I el'aim,and desire to secure by Letters Patent of theUnited States, is-

In a lubricator for steam machinery, the combination, with an oil-cup, A, open at both ends and provided with screw-threaded stoppers, of the oil-tube D, provided with a collar or enlarged lower end seated steam-tight upon the plug II, a nut with an opening through it for securing the tube firmly to its seat, the pointed screw-pin F, to regulate the iiow of oil into the tube D, and the nut G, substantially as set forth.

In testimony whereof I have hereunto subscribed my name. i

GEORGE Z. CLARK.
