LUBRICATO R.

SPECIFICATION forming part of Letters Patent N 0. 636,185, dated October 31, 1899.

Application filed March 8, 189 9- To all whom, it may concern.-

Be it known that I, GEORGE H. W. RUNGE, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Lubricators, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to a lubricator by means of which a continuous feed of oil may be'effected through various conductors leading to various points, the flow of oil being maintained by means of compressed air and spring-pressu re exerted thereon.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective view showing my improved lubricator. Fig. II is a vertical sectional view taken through the oil-reservoir and compressed-air chamber.

1 designates an oil-reservoir having an inlet 2, closed by a cap 3. To the lower end of this reservoir is fixed a discharge-pipe 4.

5 designates a chamber into which air may be introduced and compressed, the said chamber having communication with the reservoir 1 by a connecting-pipe 6. The chamber 5 is supported bya cross-piece 7 and the connect ing-tube 6.

Within the chamber 5 is, a piston 8, supported on a coil-spring 9, that rests upon a removable cap 10, secured to the lower end of the chamber. At the upper end of the chamber is a nipple 11, the end of which is closed by a removable cap 12, and from this nipple into the interior of the chamber communication is controlled by a springcontrolled check-valve 13, that prevents the escape of air from the interior of the chamber after it has been forced therein by means of a suitable pump applied to the nipple 11 on the removal of the cap 12. The pipe 4 contains a valve 14.

15 designates cocks that may be located in any desirable positions Where there are journals to be-lubricated, these cocks being provided with set-valves 16, by which the quan tity of oil flowing through the cooks may be controlled to a nicety, so that any desired feed of oil may be attained. The cocks are Serial No. 708,260. (No model.)

In the supply-pipe 18 are

bends

19 and 20.

Between the

bends

19 and 20 is a union 21, containing a turn-joint the sleeve of which is held in place bya set-screw 22. The pipe 18 is connected to the discharge-pipe 4 by a union 23, containing a turn-joint the sleeve of which is held in place by a set-screw 24. By providing the

bends

19 and 20 in the supply-pipe 18 and introducing the

loose unions

21 and 23, that provide for a universal movement of the parts with relation to each other, either part may be mounted on a movable support without the moving of such support effecting the operation of the device.

This lubricator is well adapted for use in supplying lubricant to the journals of caraxles, or it may be used in lubricating journals of any other description. The coupling 18 of the supply-pipe 18, by which it isjoined to the delivery-pipes 17, is provided with an extra arm 18, by which a second set of cocks may be connected by suitable piping to the supply-pipe 18 and be fed therefrom.

In the operation of this lubricator the res= ervoir 1 is filled with oil and air is pumped into the air-chamber 5, so as to be compressed therein, by attaching a pump to the nipple 11 on the removal of the cap 12. In compressing the air into the chamber 5 the piston Sis forced downwardly,contraoting the spring 9 and moving the piston to the lower end of said chamber. The valve 14 is then opened when it is desired to start the flow of oil to the cooks 15, and the pressure of the compressed air fiowing from the chamber 5 through the pipe 6 into the oil-reservoir presses the oil out of the reservoir gradually, causing it to flow through the pipes 4, 18, and 17 to the cooks 15 and feeding it to the journals to be lubricated.

I claim as my invention-- 1. A lubricator comprising an oil-reservoir, a discharge-pipe leading from the reservoir, a compressed-air chamber, a pipe of less diameter than the reservoir and chamber, connecting the compressed-air chamber with the oil-reservoir, and the spring-piston located 2. A lnbricator comprising an oil-tube havcoil-spring, and the pipe connecting the up 16 ing an inlet at the upper end of the tube, a per ends of the oil-tube and air-tube and of cap closing the inlet, a discharge-pipe fixed less diameter than the said tubes; substanto the lower end of the oil-tube, an air-tube tially as described.
