STEAM-ENGINE LUBRICATOR.

SPECIFICATION forming part of LetterspPatent No. 412,393, dated October 8, 1889.

Application filed June '7, 1889. Serial No. 313,476. (No model.)

to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to lubricators for steam-engine cylinders; and it consists of certain novel and useful features of construction, clearly Set forth in the following specification and claims, reference being had to the accompanying drawings, illustrating my device, and of Which- Figure l represents a side elevation of an oil-reservoir and -pipes connecting it with the Steam-pipe, and Fig. 2 is a sectional viewof the same.

Similarv letters of reference indicate identical parts throughout.'

.. A is an oil-reservoir, provided with a cockv a and a projecting pipe a orother means for connecting the reservoir with the pipe B,

which is closed, preferably, by means of a removable plug b or its equivalent. The' pipe B is also connected with the steam-pipe C by the pipe D, provided with a valve d. The reservoir A is provided upon its top with a dome or chamber A', which is simply a continuation of the main chamber and may be cast integrally therewith, if desired. This chamber A is provided with a lateral proj-ection A2 and with a faucet A3. The top of the chamber A is secured in .place by means of screw-threads or in anypreferred manner, and is provided with a screw-threaded Socket a5 for the reception of a rod or pipe a2, which may be termed a A support, also screwthreaded at a portion of its length near each of its ends. The support a? is provided at its upper extremity with two nuts d3 a4, between which is placed one end of the block b', project-ing laterally from the support, and this lateral projection passes loosely over the end of the part a2 and is adjustable thereon, being raised or lowered by means of the nuts a3 a4. The opposite extremity of this lateral pro. jection is provided 'with a screw-threaded opening to permit the insertion of asection of pipe h2, also screw-threaded, which connects with the pipe h3, having a valve b4 and lead- 55 ing into the steam-pipe. A socket b5 is provided on the under side of the block or lateral projection b around the mouth of the pipe h3, for the reception of the upper end of the glass D', whichI term a sightrfeed, and 6o a Similar socket is provided in the part A2 to receive the lower end of said sight-feed glass. The part A2 is also provided with a valve g and valve-seat g', of ordinary construction, with the exception that the part in which the valve-seat is formed is constructed so as to form a support for the wire E, which passes through the glass and through a nipple e in the part A2 and enters the pipe b2. The block or lateral projection b being adjustable on 7o both the rod a2 andpipe b2,.it-is obvious that glasses of different lengths may be used, as desired.

The operation of my device is as follows:

l The stop-cocks d and b4 inthe pipes. D and 75 b3 are closed, also the cocks a and a7, the valve g being left open. Water is then admitted to the` pipe B by removing the plug b until the reservoir A, chamber A', glass, and pipel)3 are filled. The plug b is then re- 8o placed, and the faucet A8 is connected by rubber tubing or other preferred means with an oil-supply tank and the valve g closed. The stop-cocks a and a7 are then opened, permitting the water to escape from the reservoir and the oil to iiow in. As the water passes out, a vacuum is formed in the upper portion of the reservoir A, and the oil enters through the faucet A3, and is allowed to flow in until the water stands at the level of the 9c faucet a, when the supply is cut off and the cock a closed, leaving the main portion of the reservoir iilled with oil, while the lower portion contains water to the height of the faucet a. rlhe pipe B, connected with the lower eX- tremity of the reservoir, is also filled with water, as is the sight-feed glass D The valves g, h4, and d are then opened, when the weight of the column of water in the pipe Bwill force the oil against the under surface of the water 10o in the glass. The lower extremity of the wire E is in contact with the oil, and the pressure of the water in the pipe B forces small particles of oil through the water in the glass and along the wire, which acts as a guide until it enters the pipe b3, from which it flows into the pipe C, where it mixes with the steam as it enters the cylinder and serves to lubricate the action of the piston.

The water-supply in the pipe B is maintained by means of the condensation oi' steam, which enters thelpipe D from the pipe C.

Instead of using the column of water in the pipe B for the purpose described, I may, if I desire, connect the oil-reservoir with the ordinary water-supply of a city or town, as shown in dotted lines.

What I claim, and desire to secure by Letters Patent, is l l. In a lubricator, the combination of an oil-reservoir and tubular connections leading from its upper and lower extremities into the steam-pipe, the said reservoir having a supplemental chamber provided with an oil-inlet for supplying the reservoir, substantially as described.

2. In a lubricator,the combination, with an oil-reservoir, of a supplemental chamber at tached to the same, having a lateral hollow projection and asight-feed glass supported at one end by said hollow projection and connected therewith, the opposite end of said glass being held in place by a vertically-adjustable connection, substantially as de scribed.

3. In a lularicator, the combination, with aan oil-reservoir, of a supplemental chamber opening into the same, having alateral hollow projection, a valve and valve-seat Within said projection, a sight-feed, and an oil-guide within the same, the said oil-guide being supported by the valve-seat, substantially as described.

4. In a lubricator, the combination, with an oil-reservoir, of a sight-feed glass and an adjustable support for one end of the same,

whereby glasses of diierent lengths may be used, substantially as described.

5. In a lubricator, the combination, with an oil-reservoir, of a support extending from the same and a lateral projection from said support, adjustable thereon, for the reception of one end of the sight-feed, substantially as described.

6. In a lubricator, the combination, with an oilreservoir, of a support extending from the same and a lateral projection from said support, adjustable thereon, for the reception of one end of a sight-feed glass, the said lateral projection being adapted to permit the passage through it of a pipe connecting the sight-feed glass with the steam-pipe, substan tially as described.

7. In a lubricator, the combination, with an oil-reservoir, of a supplemental chamber above the same, a rod. secured to the top of said chamber, screw-threaded a portion of its length near the upper extremity, a movable part fitting loosely upon said rod and extending laterally and adjustable thereon by means of nuts, a sight-feed' glass, one end of which is supported by said movable part, and a pipe passing through said movable part, adjustable therein, for the purpose of connecting the sight-feed glass with the steam-pipe, substantially as described.

8. In a lubricator, the combination, with an oil-reservoir, of a water-supply for forcing the oil into the steam-pipe, a sightffeed glass, pipes connecting said reservoir and said sightfeed glass with said steam-pipe at two points, one above the other, both of said points being above the reservoir, and a wire extending through the sight-feed glass for guiding the oil, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
