LUBRICATOR.

I Specification of Letters Patent.

. yatented July it, 1915.

Application filed .Tune 24, 1914. Serial M1397.

To all whom it may concern "Be it known that 1, JOHN L. ALLEN, a citizen of the United States, and resident of Manville, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

'This'"invention relates to lubricators ofsuch as oil or the like is adapted to pass, and

to provide a passage-way between the two through which a portion of the oil in its passage through the conductor may enter the receptacle and equalize the pressure therein, and to force the graphite contained in the receptacle through said passage-way to'be picked up by and mixed with the flowing oil and be conducted thereby to the parts to be lubricated.

A further object of the invention is to provide a vent opening leading from the upper portion of the receptacle into the conductor. seas to prevent the generating of undue or excessive pressure in the upper portion ofthe receptacle, which would have a tendency to force the liquid rapidly from the chamber. It is found in practice that under normal conditions the fiow is verygradualand a full receptacle would last a matter of two or three days, but when an undue pressure is generated in the receptacle the contents may be forced out in about an hour or two.

A further object of this invention is to provide a sh t-ofi' valve in said receptacle for controlling the discharge conduit and also a valve for controlling the vent open- 1ng.. 1

With these and other objects in view, the

invention consists of certain novel features of construction, as willbe more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1- is a diagrammatic view illustrating one I method of connecting my improved lubri-.

cater to the main steam pipe of an engine. Fig. 2- is a sectional elevation of my improved lubricator. Fig. 3- is a sectional View on line 33 of Fig. 2. v

Referring to the drawings 10 designates the receptacle for containing a non-liquid lubricant such as graphite, or the like, the same being constructed in. the form of a cup with an opening at its topand a cap or plug 11 threaded therein. In the drawing I have also illustrated an oil channel or passage-way 14 formed in a boss 15 .integral with the side of the receptacle adjacent to the chamber, the axis of this-channel being substantially parallel with that of the chamber. The upper end of this boss is threaded as at 16 to receive an oil conductor pipe,

or tube 17, and the lower end of the boss is threaded as at 18 into which a check valve 19 of any suitable construction may be screwed through which the oil supply function. Adjacent the bottom 20 of the receptacle I have formed a threaded openpasses on its way to perform its lubricating I ing 21 into the oil channel 14, and into this opening I have screwed a bearing 22, in which is mounted the valve stem 23 threaded at 24: near its inner end and the valve 25 on the stem is adapted to be moved to close the aperture or conduit 26 leading from the receptacle near the lower portion thereof into the conductor I l.

A feature of my improved invention is the provision of a ventopening in the upper portion of the receptacle to prevent the formation-of an undue pressure in the upper end of the lubricant receptacle. To accomplish this I have provided an opening 27- leading through the side wall of the receptacle into the conductor 14, and have provided a valve 28 adapted to be screwed by means of the handle 29, and the stem 30 to close the opening 27 when desired.

It is found in the practical use of my improved lubricating device that in some cases Where the pump which forces the oil through the conductor 14 is not submerged in the oil it often times forces a quantity of air along with the oil in -which case the air in passing the opening 26 will shunt-o5 into the receptacle and upon rising to the top thereof create a pressure therein suiiicient to force the contents of the receptacle'out through the opening 26 in a very short time, rendering action of the device very diflicult to control. I have entirely obviated this difliculty by providing the vent opening 27 which permits this air in the top of the receptacle to pass freely outward and back into the conductor pipe and so pass on with the lubricant and thus prevent an excessive pressure forming in the receptacle and forcing the contents out too rapidly. In some cases when there is no air in the system the valve 28 may be closed, if desired.

In practice my improved lubricator may be attached in any convenient manner to automatically mix graphite or other non-liquid lubricant with oil and. supply this mixture to the parts to be lubricated. In Fig. 1 of the drawing I have shown the apparatus as connected to supply the combined oil and graphite 'to the main steam supply pipe 31 to an engine cylinder 32. In this device the oil is placed in the cup 33 and is forced, by means of the usual pump 34: actuated from the moving parts of the engine, through the oil conducting pipe 35 up past the graphite receptacle 10. The valve 25 to the graphite chamber is now opened and a very small portion of the .oil, in traveling upward through its conductor, works its way in through the opening 26 and the body of the graphite to the top or above the same, and so equalizes the pressure in this cham ber whereby the gravity of the graphite causes it to settle and work slowly outward through this aperture where it is picked up by the flowing oil and carried on as a mixture into the main steam pipe 31. By placing the opening at the lower end of the receptacle practically all the contents thereof may be forced out each time it is charged, and the quantity of the flow through this aperture may be nicely controlled and regulated by simply adjusting the valve 25.

y my improved construction it will be seen that the oil conductor is wholly on the exterior of the graphite chamber and is so arranged that the communication between' the graphite receptacle and the conductor may be shut ofi' by the valve 25 whereby the cap of the graphite chamber may be removed for inspection or repairs and filled or recharged with graphite as often as may be desired without in any way interfering or affecting the continuous flow of oil through valve that controls the vent in the one that controls the discharge conduit.

I claim: I 1

. 1. A lubricator comprising a receptacle for containing non-liquid lubricant, a conductor for a lubricating fluid adjacent said receptacle, an inlet opening leading, from said conductor to the lower portion of said receptacle,'said receptacle being also provided with an air vent opening near its upper end leading into said conductor.

2. A lubricator comprising a receptacle for containing non-liquid lubricant, a conductor for a lubricating fluid adjacent said receptacle, an inlet opening leading from said conductor to the lower portion of said receptacle, said receptacle being also provided withan air vent opening near its upper end and leading into said conductor, and

shut-off valves controlling said openings.

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