LUBRICATOR.
Specification of Letters Patent.
Application filed. December 12, 1914. Serial No. 876,968.
To all whom it may concern:
Be it known that 1, CHARLES A. MINSKER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Lubricators, of which the following is a specification.
This invention relates to lubricators or oil cups of that class which are adapted to be used partly in connection with air pump cylinders for the purpose of lubricating the same, the construction being such as to feed a predetermined quantity of oil on the suction stroke of the piston, while on the compression stroke the oil fed is obstructed.
The invention has for its object to produce a device of the class described which will be simple in construction and which will permit of the quantity of oil fed on each pulsation of the pump to be accurately gaged or regulated.
A further object of the invention is to produce a device of the character described which is equipped with what may be termed an auxiliary feed whereby, upon the first starting of the pump, the quantity of oil fed will exceed the quantity fed at a later'stage when a less quantity is required.
With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.
In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.
In the drawing, Figure 1 is a vertical sectional'view of a lubricator constructed in accordance with the invention. Fig. 2 is a horizontal sectional view taken on the line 22 in Fig. 1. Fig. 3 is a top plan View. Fig. 4 is a sectional detail view on a larger scale of the valve and related parts.
may be observed. A cap or cover 16 having threaded connection with the upper end of the cylindrical body is provided with a filling aperture 17 which may be obstructed by a slide cover 18. Said cover also has an axial threaded aperture for the passage of the upper threaded end of a stem 19, the
lower end of which has a bore 20 which communicates with the interior of the easing through an aperture 21. The lower unthreaded end of the stem 19 passes through a packing box 22 in a diaphragm 23 near the lower end of the cylindrical casing, and the lower extremity of the stem is provided with a valve seat 24.
Threaded uponthe lower end of the casing 15 is a valve casing 25 having a downwardly extending externally threaded nipple 26 whereby it may be mounted on the pump cylinder that is to be lubricated. The bore of the nipple 26 is expanded at its upper end to form a valve seat 27. 28 is a valve having an annular flange 29 and an upwardly extending stem 30 guided in the bore 20, said valve being adapted to alternately engage the seats 24L and 27 The diaphragm 23 is provided with downwardly extending pins or lugs 31 lying in the path of the valve flange 29 which, however, does not normally engage said lugs during the operation of the device, said lugs being provided for a special purpose which will hereinafter be made apparent.
The diaphragm 23 has an aperture 32 communicating at its upper end with a tube 33 that extends upwardly within the casing 15 and which terminates at its upper end in a ported valve seat 34 normally obstructed by a valve 35 which is held on the seat by the action of a spring 36. The lower end of the aperture 32 communicates with a duct Patented Nov. 23, 1915. l
thus enabling said stem to be adjusted verti cally by the engagement of its threaded p'ortion with the-threaded aperture in the cap 16. It follows that by adjustment of the stem the distance between the valve seats 24% and 27 maybe varied, thereby varying the flutter or pulsation of the valve. It will also be seen that the stem 19 may be raised to a point Where the valve will no longer engage the seat 24, its upward movement being arrested by engagement of the annular flange 29 with the lugs 31.
The operation and advantages of this device will be readily understood from the foregoing description, taken in connection with the drawing hereto annexed, by those skilled in the art to which it appertains. When suction is exerted through the bore of the nipple 26 the valve will engage the seat 27, and oil will'fio-w from the casing or receptacle into the valve chamber. When pressure of air or other liquid is exerted through the bore of the nipple the valve will engage the seat '24, and lubricant will be free to pass through the bore of the nipple, the quantity of lubricant liberated on each pulsation being determined by the extent of the pulsation of the valve. At the first starting of the pump, when it is desired to feed an extra quantity of lubricant, the casing may be filled until the level of the oil rises above the tube 33. Then, when suction is first exerted through the nipple, the spring actuated valve 35 will become unseated, and the oil above the level of the tube 33 will be drawn through the tube, through the duct '37 and through the bore of the nipple. After the level of the contents of the casing falls below the top of thertube 33, the action of the valve 34 no longer affects the flow of lubricant.
Should the various ports or passages of the device become obstructed or clogged in any way, the device may be readily cleansed by temporarily raising the stem 19 to a point where the seat 24 will be beyond the reach of the valve 25. Air or steam may now be blown through the bore of the nipple, serving to clear out any obstructions that may have lodged in the device. This cleaning operation, of course, should be performed when the device is empty of lubricant.
Having thus described the invention, what is claimed as new, is J 1. A lubricating device comprising a receptacle, a valve chamber at the lower end thereof and having a threaded nipple, the bore of which forms a valve seat, a diaphragm separating the receptacle and the Valve chamber, a stem extending through the diaphragm and having at its lower end a bore terminating in a valve seat, the wall or, said bore being provided with an aperture communicating with the interior of the receptacle, and a valve within the chamber adapted to alternately obstruct the two valve seats.
2. A lubricating device comprising a receptacle, a valve chamber at the lower end thereof and having a threaded nipple, the bore of which forms a valve seat, a diaphragm separating the receptacle and the valve chamber, a stem extending through the diaphragm and having at its lower end a bore terminating in a valve seat, the wall of said bore being provided with an aperture communicatng with the interior of the receptacle, and a valve within the chamber adapted to alternately obstruct the two valve seats, the stem being provided at its upper end with a threaded portion having a handle; in combination with a cap or cover for the receptacle having an axial threaded aperture through which the threaded portion of the stem is guided.
