A ppieaticn filed March 15, lS,

To (LZZ '1r/'7107211 it may concern:

Be it known that I, VILLIAM R. HOLDER, a citizen of the United Sta-tes, residing at Verbena, in the county of Chilton and State of Alabama, have invented certain new and useful Improvements in Lubricntors, of which the following is a specification, reference being had therein to the accompanying draw ings.

rlhis invention relates to lubricators provided with a glass gage or tube through which the operation can be watched; and it consists in certain improvements in the construction of the same, as hereinafter described, and specifically set forth in t-he claim.

In the accompanying drawings,Figu1'e l represents in vertical section a lubricator oonst-ructed in accordance with my invention. Fig. 2 is a horizontal section of a three-way Cock used therewith.

Like letters represent like parts in all the gures.

A represents the oil-reservoir. It is counected at its lower portion by means of a pipe, A2, with the pipe G, conducting steam from the boiler to the engine. The pipe A2 is provided with a valve, a, adjacent to the pipe G, and a valve, a?, adjacent to the reservoir to regulate the amount of incoming steam. The bottoni portion of the reservoir A is provided with a downward passage, B, leading to the drip-cock B', attached to the shell of the reservoir A. In the center of the bottom of the reservoir A is a recess or chamber, G, communicating with a passage, C, into which is received one end of the pipe G2, leading to the lower end of the glass tube D. "Within the upper portion of the reservoir there is a horizontal spider or guide, A3, for the upper end of the tube E, while itslower end enters the recess orchaniber C, and is supported on the bottoni of the reservoir by the fiange E. The guide A3 is provided with a series of perforations, e', for the passage of oil. In the upper portion of the reservoir A and under the guide A3 is a pipe. D', which connects the reservoir with the steam-pipe G, and upon said pipe D is a plug-ilalve, F, the lower portion of which receives the upper end of the glass (No modul.)

tube Dand retains itin position. The plug F is a three-way plug to permit the use of the aparatus evenafter breakage of the glass tube, as will be hereinafter described. The cover H is screwed into the shell ot' the reservoir A at h, and carries at its upper end astutting-box,tl1rough which aserewthreaded stem, H', passes, and its conicil lower end is so formed that it can take a seatin the opening at the top of the tube E, so that the amount oi oil fed by the lubricator can be regulated by the adjustment ot' said screwthreaded stem H.

The operation of the lubricator is as follows: Wvater having been placed in the glass tube D either before connecting the lubricator to the pipe G or from condensation ot'. a small current ol' steam passed through the apparatus, 'the plug F is given half a turn from the position shown in Fig. 2, and either the valve n. or at is closed. The top of the reservoir is then opened and thelattcr filled with tallow or any suitable oil to lubrieate the cyl inder. The cap is then replaced andthe stem H screwed down until it rests upon the end ofthe tube F. The valve a is then opened wide and the valve fr just enough to operate the device. The stem H' is then slightly unscrewed and a portion ofthe oil iioating upon the condensed water in the reservoir iirst descends in the tube E, and drops of oil are seen to ascend through the water in the glass D. The plug F is then turned, as shown in Fig. 2, or enough to admit the oil into the steampipe G, but the supply is controlled mainly by the screwthreaded stein Il. rElie plugvalve F is so constructed that in case the glass tube D is broken the oil can be automatically fed direct from the reservoir A through the discharge-pipe D into the steam-pipe G by giving the plug F one quarter turn from the position shown in Fig. 2, and closing thelower end of said plug.

Then it is desired to refill the reservoir with oil, dre., the cover H is removed and the drip-cock B opened to allow the water of condensation to escape from the reservoir.

Having now fully described my invention, I claim- A lubricator consisting of the reservoir A,
