LUBRICATO R.

SPECIFICATION forming part of Letters Patent No, 277,464, dated May 15, 1883.

Application filed March 12, 1883. (No model.)

To all whom it may concern:

Be it known that I, WARREN HILLIARD CRAIG, of Lawrence, in the county of Essex and State of Massachusetts, haveinvented new and useful Improvements in Lubricators, of which the following .is a full and clear descrip- [1011.

This invention relates to that class of lubricators in which the lubricant is displaced by the admission of condensed steam to the-oilreservoir, thereby forcing the lubricant from 'the cup or reservoir through the outlets provided therefor to the parts of the machine to be lubricated.

My invention consists in a novel construction of parts and chambers by which the water may be regulated and seen as it passes downward through the lubricant, and also the lubricant can be seen as it passes to the steaminlet or oil-outlet, to be discharged through the same to the steam-pipe of engine.

Figure l is a side elevation. Fig. 2 is a section taken on a plane with Fig. 1. Fig.8 is a section taken atright angles to Figs. 1 and 2.

In Fig.2, A is the steam-inlet, provided with a tube, 1), extending up into condenser B, in which the steam becomes condensed to supply the water for displacing the oil. In the lower portion of A there is a chamber,'a, provided with a partition, 0, curved at the bottom and extending up past the steam'inlet, thus formin g a wa-tentrap. Directly in front of partition C, and on 'a line with the steam-inlet A, is a glass plate or observation-port, D. In the bottom of chambera is a tube, 6, connecting with the oil-chamber E. Directly in front of the observation-port D artitiop g isd ighlan polished to for n a light-rm It will thereiore be fih d e rstood that ,the lubricant, when displaced by water, as hereinafter described, will pass out of tube a up through the water condensed in the trap a, and be seenas it passes the observation-port I) and over the polished portion of partition 0, orin close connection thereto, and discharging over partition 0 to the steam-pipe of engine-cylinder. By reference to Fig. 3 the displacement of the lubricant by water will be more clearly understood. The steam, having entered the condenserB through the pipe b, becomes condensed into water. passing down passage F to the oil reservoir E. The lowerportiou of passage F is provided with a valve, f, and a valve-seatprojection, G, extending into the oil-reservoir E, valve-seat projection G being provided with a passage,.g, leading upward from seat of valve f to the upper portion of valve-seat projection G, where it is provided with a recess or opening leading to the polished face of valveseat projection G, and is better shown at h in elevation, Fig. 1. In front of recess or opening it, and ona line with valve f, is arranged a glass pane or observation-port, H, in close connection with the polished face of valve-seat projection Gr, so that the drop of water, after leaving the recess h. may be seen as it passes down between the glass pane and the polished face of the valve-seat projection G. The advantage of the upward passage g and the recess h, in connection with the valve seat projection G, over that shown and described in a previous application by me for Letters Patent on improvements in lubricators is that the oil, after the discharge of the water-drop, does "not back into the water-outlet and have to be forced at each discharge. The drop being formed in the recess 11, when it attains a proper size it will leave the recess and pass down between the polished valveseat projection G and the glass'pane H, leaving the upward passage 'g filled with water and continuing to feed, no extra head of water being required to insure a continuous and regular feed.

In Fig. 1, I is a valve provided with a hopper through which the reservoir is supplied with oil. Valve J, at the extreme bottom, is used to draw the fluid from the reservoir. The manner in which the lubricator is usually attached to the steam-pipe of engine is by means of a union made fast to the steaminlet A and connecting with a valve commonly in use to the steam-pipe of engine, thus allowing the lubricator to be removed at any time when the steam-pipe of engine is filled with steam.

I am aware that my invention may be applied in different ways, one of which is by closing or dispensingwith the tube 1) and connecting a pipe to the top of condenser B and connecting it with the steam-pipe of engine,

using the steam-inlet Aas an oil-discharger ervoir and located below the glass pane and only; but the way I have shown it is preferab e.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a lubricator, a steam-chamber provided with a partition, 0, extending up nearly to top of such chamber, and arranged so as to form a water-trap in the lower portion of said steam-chamber and extending to the top of partition O, the water-trap to be provided with a drop-tube, e, connecting-it to the oil-reservoir, the trap also having a glass pane directly in front of the polished portion of partition 0, located above the drop-tube a, substan tially as shown and described. l

2. In a lubricator, a water trap or chamber provided with a glass pane or observation-port directly in front of a highly-po1ished reflector, and containing a drop-tube leading to oil-res reflector, and having a discharge "above the same to the steam-pipe, substantially as shown, and for the purpose described.

3. In a lubricator, the combination of the water-valve f, valve-seat projection G, having an upward passage, g, recess h, and polished portion with observation-port H,arran ged substantially as shown.

'4. The projection G, set in close connection with the glass pane and provided with openward and connecting through the chamber of valvef with the water-passage F, substantially as shown and described. a
