SPECIFICATION formng part of Letters Patent No. 264901, dated September 5, 1882. Application filed February 14, 1882. (No model.)

10 all whom it may concem: O

Be it known that I, CLAUDIUS VERNIAUD, of Quincy, in the county of Adams and State of lllinois, have invented certain new and useful Improvenents in Lubricators for Steam Machinery and I hereby declare the following to be a full, clear, and exactrdescription ot' the same, reference being had to the acconpanyin g drawings, formin g apartof this speci- -fication, in which- Figure 1 is a vertical sectional view of my invention, showing its practical application to the steam-pipe of an engine. Fig. 2 is a seetional View of oneof the fittings detached. F g. 3 is a cross-seetional view of a condeser having longitudinal corrugations instead of lateral corrugations, asin the condenser shown in Fig. 1.

Similar letters ot' reference in the several figures denote the same parts.

This invention consists ot' an improved lubricator for steam machinery, constructed and operated as will be hereinafter full y described, i and pointed out in the claims.

In the accompanyin g drawin gs, A represents the oil chamber or reservor; B, a fitting se-- cured to the upper'part of the said chamber A, having a passage, b, leading into a vertical glass tube, C, and adapted to be opened and closed by means of a valve, D, and having another independent passage, b', leading from the said tube G into a globe-valve, E, connected to the steam-pipe S, which leads to the part of the engine to be lubricated.

B' is another fitting, similar to the fitting B, connected to the lower part of the oil-chamber A, and having a pipe, H, connected toit within the oil-chamber, and extending up vertically within the clamber to a point at or above thepassage b of the upper fitting, B, as shown. The fitting B' has passages c, c', ende similar to the passages I b' I) in the upper fitting, the passage c, leading into the pipe H, the passage c' leading into the lower end ot' the glass tube C, and being controlled by the valve D, and the passage 0 leading from the glass tube C into another globe-valve, E', connected to the pipe S. The connections between the fittings B B' and the oil-chamber A, the glass tube C, and the globe-valves E E' are all made air and water tight.

F represents the condenser, from the upper end of which extends a pipe, F', leading into the steam-pipe S, and having a check-valve, V, arranged in it. From the lower end of said condenser leads a pipe, G, that passes down into the oil-chamber to within a short distance of the bottom thereof, as shown, beingprovided with a controlliug-valve, K, between the oil-chamber and the condenser.

J represents a plug in the upper part of the oil-chamber, which can be removed for the filling of said chamber with oil, and I is a pet cock, by which the contents of the oil-chamber can be drawn ofi' when desired.

The oil-chamber being filled with oil and the valves D D' E E' being closed, the oiler may be operated as follows: Steam from the steampipe S enters the pipe F', passes the check-valveVtherein, and enters the condenser F. The valve K is then opened more or less,

so as to allow the water of condensation to pass to the bottom of the oil-chamber. The valve D may then he opened, so as to permit the oil to pass through the passages b b' into the glass tube 0 until the quantity of oil is admitted to the said glass tube sufficient for a charge. The valve D is then closed. The globe-valve E' or both the globe-valves E and are opened and the charge of oil is caused to pass into the steam-pipe S, to be thence conducted to the parts of the engine to lubricate it.

Instead of opening the valve D to chargc the glass tube C, the valve D' maybe opened, whereupon the oil will pass down the pipe H and through the passage c c' ot' the lower fitting, B', into the glass tube G, and then, upon the valve D' being again closed, the charge of oil in the glass tube O may be discharged into the steam-pipe by manipulation of the globe-valves E E', as before. Two ways of charging the glass tube C are thus provided, and if either one or the other set of passages from the oilchamber should from any cause become stopped the other set would prove effective.

If it is desired to suppl y the oil con tinuousl y from the oil-chamber to the steam-pipe instead of in charges, as described, this object can be readily acconplished by leaving one or the other or both ot' the oil-valves D D', as well as one or both of the valves E E', open slightly, as will be readily understood.

In order to afl'ord as great a condensing-surface as possible within conparatively small compass, I preferably corrugate the condenser either longitudinally, as 'shown in Fig. 1, or laterally, as shown in Fig. 3.

The check-valve in the pipe F' is for the purpose ofpreventin g the oil from being all sucked out of the oil-chamber When theengineis work-` ing with stean shut off, and is consequently producing a partial vacuum in pipe S. When steam is in the pipe S the cheek-valve opens and admits it into the condensing-chamber; but when the steax is cut off with the engine still working the partial Vacuun formed in the pipe S causes the check-Valve to close, and all communication with the ol-chanber is thereby closed.

I claim as my invention 1. The eombination of the oil-chamber, the condenser, and the pipe leading from the condenser into the oil-chamber with the chargingtube C, having the upper and lower fittings, each adapted to receive oil through {an overflow-passzge within the oil-chanber and discharge it into the charging-tuhe, and each also having an independent passage leading.

to the steam-pipe, and with Valves for controlling the flow of oil into the opposite ends of the charging-tube, and valves for controlling the flow of oil through the independent passages to the stean-pipe, substantially as described.

2. The combination of the oil-chamber, the condenser, and the pipe leading therefrom to near the bottom of the oil-ehamber with the upper and lower fittings, B B', their passages and valves, the vertical pipe connected to the lower fitting within the oil-chamber, the glass chargin g-tube, and the globe-valves con neeted to the fittings and to the stean-pipe, substantially as described.
