llNiTnD STATES RICHARD M. GELINAS, OF SEATTLE, lVASHlNGTON, ASSIGNOR OF ONE-HALF TO THOMAS F. COLBERT, OF SAME PLACE.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 590,974, dated October 5, 1897.

Application led December 16, 1895. Serial No. 572,364. (No model.)

t provide an easy method of filling lubricators and one by which t-he spilling or Vwasting of any oil may be prevented; second, to avoid the conducting of a steam or condenser pipe through the oil in the lubricator, and thereby zo to prevent the heating or changing the temperature of the oil, and thereby to avoid any interference with the transmission into the steam-supply pipe of the amount of oil desired; third, to avoid the frequent delay after filling in again putting the lubricator into operation, and, fourth, to avoid the frequent and usual necessity, in the ordinary lubrica` tor, after filling, of resetting the feed or again regulating the amount of oil to be transmitted. l These objects are attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation of my device, and Fig. 2 is a central longitudinal sectionof the 3 5 same.

Similar letters of reference refer to similar parts in both the figures.

The lubricator consists, in the first place, of a large central cylinder or cup A, as a re- 40 ceptacle for the oil, and having a rounded or bell-shaped cap F at the top, and which is to be removed when the cylinder is to be filled. This cap is not screwed on and is removed merely by lifting. At the upper part of the cylinder and on the inside, at a point S just below where the cup is adjusted to the cylinder, is a' strainer for the keeping of dirt or dust from the oilbeneath. Joining on the cylinder at the bottom is a condenserglobe L, and projecting downward from this is a drain-cock G, by means of which the water may -be drawn from the condenser- `globe. Connected with said globe is a pipe known as the condenser-pipe7 K, in which is a valve D, which respectively transmits and regulates the transmission `of the steam or water into said globe. At one side and projecting from the central cylinderA is a gage glass tube R for determining the amount of oil in the cylinder, and at another side of 6o said cylinder is a sight-tube N for gaging the transmission of the oil from the cylinder into a pipe O, leading` into the steam-supply pipe B. In the interior of the cylinder, running lengthwiseV and from a point a little below the strainer S and valve-seats of the oompression-valve-hereinafter mentioned, is still anothertube M, which extends to the bottom of the cylinder and connects with a short pipe leading to the aforesaid sight-tube'N. 7o In this short tube just mentioned, between said cylinder and said sight-tube and midway therein, is a feed-valve P for the regulating of the amount of oil to be transmitted through said sight-tube and into said steamsupply pipe B. Finally, and in the interior of the cylinder, and one of the most distinctive features of this invention, andextending when raised from the top of the condenser-globe to nearly the top of the cylinder 8o proper and to a-'point V V a little above the top of the tube M and just below where the cap iits on the cylinder, is a compressionvalve H. This valve consists of three partsthe valve proper, H', the stem H2, and the 85 hollow bell-shaped piston H3. This piston slides in the neck connecting the condensation-chamber with the oil-reservoir. The upper or closed end of the bell is perforated by holes 71, to allow the water of condensation 9o 4 IOO valve leaves at V V or at S a wide opening the condenser-globe L. The seats of this valve resting for the most part in oil wear out only with difficulty. A plug C closes the pipe O where it joins the reservoir A.

The manner of operation is as follows, to wit: Close valve E, so as-to prevent the back pressure from the steam-pipe; then turn or close the valve D in the condenser-pipe, thus preventing any transmission ot' steam or water from there into the condenser-globe L; remove the cap F from the top of the cylinder; open the drain-cock G, so as to allow the steam and water which has gathered in the globe to run out, and the valve H, no longer supported by the water or steam, to drop and thus leave the cylinder open,as indicated at the top and at the points V; now close the cock G below the condenser-globe L and pour the oil in at the top of the cylinder until filled; replace the cap F; now open the valve D in the condenserpipe, and the steam and water rushing into the globe will force the valve H upward; then open the valve E in the oil-transmitting pipe O and the oil will begin to iiow from the cylinder down the tube M through the valve P into and through the sight-tube N into the steam-transmitting pipe O and supply-pipe B, whence it is transmitted to the cylinder or engine,l and the lubricator will be in full operation. The oil being lighter than water remains, of course, always on top in the cylinder, and as the condensed steam or water gathers in the condenser-globe in increasing quantity and rises into the cylinder and in the direction indicated by the arrows in Fig. 2 the oil is forced upward, together with the valve H, and the oil is forced down the tube or pipe M, and so on, as indicated above.

By my invention the ordinary method of filling lubricators by the removal or unscrewing of a plug and pouring oil through a small aperture is done away with, thereby avoiding not only considerable annoyance but also the frequent leaking incident to said plugs. Having practically the whole top of the cylinder into which to pour the oil renders any spilling or wasting impossible.

By my plan of having the condenser-globe at the bottom of the lubricator instead of at the top, as in other lubricators, there is further avoided, as before suggested, the presence of a heated condenser-pipe from a point above the lubricator down through the oil to the bottom of the cylinder. Consequently also, is there avoided the heating and sometimes boiling of the oil from contact with said pipe, and consequently, also, any interference with the regular transmission or feeding of the oil, a result that always follows any considerable change in its temperature.

\Vith my lubricator it is never necessary to wait for the oil to cool and the lubricator to operate, as the oil always remains at about the same tei'nperature. By my device of a valve E in the oil-transmitting pipe O all back pressure of steam from the steam-Supply pipe B is avoided. In other lubricators this back pressure is prevented by shutting the feed-valve P, which, however, necessitates time and trouble in resetting the same when again ready for operation. The avoidance of this is also a distinct ad vantage of my invention over others, for after having once set the feed-valve so as to provide for the transmission of the requisite drops of oil per lhour no further attention to the same is necessary.

Having fully described my invention, what I therefore claim, and desire to secure by Letters Patent, is-

1. In a lubrica'tor, the combination with an oil-reservoir havinga filling-opening in its upper end, a condensation-chamber connected to its lower end by a neck and a steam-pipe connection to said condensation-chamber, of a plungeror valve within said reservoir adapted when raised to close said filling-opening, a stem connected to the valve and a bell-shaped piston connected to the lower end of the stern so as to slide in the neck of the condensationchamber and having perforations through its upper end, substantially as shown and described.

In a lubricatorwith an oil-reservoir open at its upper end and having an internally-facing valve-seat just below the upper end,a condensation-chamber connected to the lower end of the oil-reservoir by a vertical neck, and a steam-pipe connection to the condensationreservoir, of a valve within said reservoir adapted to be raised by the steam-pressure and consisting of the valve proper, a dependent stein and a bell-shaped piston on the lower end of the stem adapted to slide in the neck of the condensat-ion-chamber and having perforations in its upper end, substantially as shown and described.

3. In a lubricator, the combination of an oilreservoir having a filling-opening at its upper end, a condensation-chamber at its lower end, a steam-pipe connection to said condensationchamber, a valve within the reservoir adapted to be held closed by the steam-pressure a guide and perforated piston sliding therein located between the condensation-chamber and oil-reservoir, said piston being connected to the valve to close the same, substantially as shown and described.
