LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 394,497, dated December 11, 1888.

Application filed J'unelS, 1888. Serial No. 276,979. (No model.) Patented in France January 12, 1888, No. 186,375, and in Belgium May 15, 1888,110. 81,730.

To aZZ whom it may concern:

Be it known that I, JOSEPH MENSE, of Bordeaux, Department of Gironde, in the Republic of France, have invented certain new and useful Improvements in Lubricators, (for which Letters Patent were heretofore granted to me by the governments of France, dated January 12, 1888, No. 186,375, and Belgium,

dated May 15,1888, No. 81,730,) of which invention the following is a specification.

This invention relates to an improved lubricator with double feed-valve, which is operated automatically by the difference in pressure of the steam on opposite sides of the piston, so that a uniform quantity of oil is fed to the steam-cylinder; and the invention consists of a lubricator for steam-cylinders from which the oil is supplied to the cylinder by means of a double feed-valve, which is guided in a fixed sleeve, the shank of the double valve being provided with longitudinal grooves or channels for conducting the oil to the cylinder. The double feed-valve of the lubricator is operated either by the difference in pressure of the steam in the cylinder or by the pressure of the steam on the water of condensation, which collects in a chamber sidewise of the oil-chamber and communicating with the bottom of the same by a suitable channel, so that the oil is raised in the same by the water of condensation and supplied at the upper part of the same to a perforated feed-pipe. The play of the double feed-valve can be regulated by a suitable spindle, the eccentric or cam-shaped inner end of which sets the feed-valve to the proper relative position to its guide-sleeve, as will appear more fully hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 representsavert-ical central section of my improved lubricator for steam-cylinders, which is operated by the pressure of the steam in the cylinder on the water of condensation collected in a part of the lubricator. Fig. 2 is a vertical central section of a lubricator which is operated automatically by the difference of pressure of the steam on the feed-valve in the cylinder and the atmospheric pressure, this form being specially adapted for condensatioi'i-engines; and Fig. 3 is a detail horizontal section of the shank of the feed-valve, showing the longitudinal channels or grooves of the same. Fig. is a cross-sectional view of the cylinder-cam at the inner end of the spindle.

Similar letters of reference indicate corresponding parts.

The lubricator shown in Fig. l is specially adapted for high-pressure steam-engines, and is operated by means of a certain quantity of water of condensation which is collected in the oil-chamber A and operated by the difference of pressure of the steam exerted on the different faces of the cylinder,which pressure is exerted on the surface of the oil by the action of the water of condensation, which gradually replaces the oil in the oil-chamber as the same is fed to the cylinder. For charging the oil-chamber A with oil, the water of condensation is drawn off, which is accomplished by means of two-way cock F, located at the lower end of the condensation-chamber B in the channel connecting the same with the bottom of the oil-chamber.

F. is a pipe for conducting the steam to the chamber B, and D is a gage for indicating the level of the water of condensation in the oilchamber A. At the center of the oil-chamber D is arranged a pipe, C,which extends in upward direction to near the top of the same, and is provided at the closed upper end with small openings through which the oil is fed into the pipe C. The lower end, C of the pipe is open and communicates with the inclosing-chamber of the double feed-valve b b. The feed-valves are connected by a shank, c, which is provided with longitudinal channels or grooves c, which serve to conduct the oil from the valve-chamber WV above the double valve to the lower part, \V', of the same and to the channel leading to the cylinder. The connecting-shank c of the valves b b is guided in a fixed sleeve, (1, which is provided with a central shoulder and threaded ends, to which the sections 0 and P, constituting the valvechamber, are screwed. The upper valve, 1), is held to a shoulder of the shank c by means of a screw-nut, d, which is applied to the threaded end of the shank, this screw-nut permitting per part of the valve-chamber into the groove m of the upper valve, Z), the longitudinal feedgroove in the spindle, and the annular groove m in the face of the lower valve, Z). As soon as the piston arrives at the end of its stroke and steam is introduced into the cylinder through the other port, it passes at the same time through the connecting-pipe E into the condensation-chamber B, and, acting 011 the water of condensation in the same, forces said water of condensation from the chambers B through the connecting-channel of the cock F into the oil-chamber A, to exert a lifting pressure on the oil therein, so as to force the same through the openings C of the central feed-pipe, 0, into the upper valve-chamber, WV. The oil thereby exerts a pressure on the upper valve, Z), and causes the same to drop back on its valve-seat, thereby delivering the oil by the ,descent of the lower valve, Z), into the lower valve-chamber and to the cylinder. As the oil is lighter than the water, the latter raises the oil to the upper part of the oilchamber and feeds the oil by the pressure of the steam on the same at each stroke of the piston without any trace of water, owing to the arrangement of the central feed-pipe in the oil-chamber, which is provided near its upper end with small feed-openings, by which the regular supply of oil takes place without any danger of feeding some of the water of condensation to the cylinder. The steam condenses in the chamber B, the water of condensation assuming the same level in the oil and condensation chambers. The play ofthe double valve Z) Z) is based on the greater length of the connecting shank or spindle than the distance of the valve-seats of the sleeve on from each other. This difference in length regulates the quantity of oil fed irrespective of the quality of the same, the play of the alternating lifting and lowering of the double valve conveying a certain quantity of lubricant from the oil-chamber to the cylinder. The quantity of oil fed to the cylinder with each stroke of the piston depends, to some extent, on the depth of the longitudinal channels in the connecting shank or spindle )of the double valve Z) Z) and on the depth of the annular grooves m in the faces of the valves Z) Z), said annular grooves in the valvefaces and the longitudinal grooves in the valve-spindle serving to transfer the required quantity of oil with each play of the valve and stroke of the piston from the oil-chamber to the cylinder, so that the quantity of lubrilarger quantity than at other times, the regulating device shown iii Fig. 2 may be arranged below the lower end of the double valve Z) Z), said regulating device consisting of a spindle, A, which is provided at its outer end with a hand-wheel, D, and which spindle is tightly secured by a shoulder, B, ina stuifing-borgc, of the part I, for preventing any escape of oil to the outside. At the inner end of the spindle A is arranged a cam or eccentric, A ,-which, on turning the spindle A by the hand-wheel B, serves to engage the downwardly-extended lower end of the valve-spindle 0, so as to slightly raise or lower the same. By this movement ofthe spindle A and the eccentric cam the spindle is raised, and

thereby the upper valve, Z), raised slightly above its seat and retained always at this distance from the same, so that the oil can pass into the feed-channels and grooves from the oil-chamber and from the same to the cylinder whenever the lower valve is detached from its seat, feeding thereby a greater quantity of oil the greater the distance of the upper valve from the valve-seat of the same.

In Fig. 2, R represents the oil -chamber, which is connected with the part 0.

The adjusting-spindle A can be used with the double feed valve of the lubricator shown in Fig. 1 or 2. In the lubricator shown in Fig. 2 the play of the feed-valve takes place alternately by the pressure of the steam on .the lower valve and the atmospheric pressure on the upper valve, the oil-chamber being in this case open at the upper end and not provided with a chamber of condensation and steam-pipe connection with the cylinder.

In this case the steam when it arrives in the cylinder presses on the lower valve, Z), and lifts the same against its seat. The upper valve being lifted at the same time permits the oil to pass into the longitudinal channels and into the annular groove of the lower valve, so as to fill the same. As soon as the action of the steam on the lower valve ceases, it drops away from its seat,while the upper valverests on its valve-seat, so that the oil contained in the channels and grooves is conveyed to the cylinder. This lubricator, as above stated, is specially adapted for steam-engines with condensers, while the lubricator shown in Fig. 1 is to be used in connection with high-pressure steam-engines.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination ofan oil-chamber, a valve-chamber below said oil-chamber, a fixed guide-sleeve in said valve-chamber, a doubleacting valve the faces of which are provided with annular grooves, a connecting-spindle having longitudinal channels communicating with said grooves, a chamber for water of conspindle having an eccentric cam, A for regulating the relative position of the double valve toward the valve-seats of the guidesleeve, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.

JOSEPH MENSE.
