8 Claims.
This inventionrelates to lubricators for use in connection withengines and is ,adapted to deliver a lubricant -toI the cylinders thereof through a pressure fluid lead; its main object being to provide a device of this kind which is especially adapted for usewith engines operated periodical- 1y, anengine typical of this form being shown in United States Letters Patent No. 1,747,899 issued yto me February 10,1930. i
v 1 y ,Another objectof this invention resides in mev provision of a novel lubricator comprising a main andan auxiliary reservoir, andra valve `which controls the flow of lubricantv from the main reservoir to said auxiliary reservoir, the lubricator being further characterized bya novel relation of pressure fluid ports or passagesand inwhich. relation `the valve of the lubricatorfunctions as a controlmember between the intake and discharge ports of the pressure fluid passage so that lubricant is `positively supplied to the desired point of lubrication by pressure iiuid means.
A further and more specific object o i the invention is the provisionof a lubricator which dis- `charges a lubricant to the cylinder walls of an enginejof the type described, the discharge of the lubricant being in advance of the movement of the piston inthe engine cylinder and prior toits `reciprocatory motion therein, thereby insuring a protectivelm of oilvfor, the engine cylinder walls `at all times. f l
Anlembodiment of the invention is hereinafter described, and is illustrated in the accompany- ,ingldrawing in which` g i Figure lis a diagrammatic sectional View showing anapplication of the invention to an engine `of vthe type described.;l
Figure 2 is a` central' vertical section of the Vlubricator showrrin'V Figure 1 `in its'normal or `closed position; and
i4 Figure 3 is apcentral Vertical section of the lubricator in its lubricant supplying phase.
Referring nowto the-drawing, a periodically operated engine` is` shown at A comprising the cylindery 10,ja piston 11 reciprocable therein, a ported head 12 coveringione end of the cylinder, and a frame member 13 which supports said en- 'gineand-forms a closure forlthe other end of the cylinder. A rod 14 isgsecured to theipiston 11 and transmits the power developed by said engine for performing any suitable operation, such as that shown in my patent heretobefore mentioned.
The piston 11 is actuated preferably by steam which is admitted to the cylinder through the ,portsV 15 and 16iaswi1l presently appear. The .pistonpis normally in3the position shown in Figure 1, the events of this piston being governed by a control valve 17, which when in its uppermost position, admits steam from the main supply lead 18 to the supply lead 19 of the port 15 for. moving thev piston towards the ported head 12, uid in advance of the movement of the piston being exhausted through the port 16, its supply lead and thence to atmosphere through the control valve. In the position shown in Figure l, the control valve 17 will admit steam from the main sup- ,55 ply lead 18 to the supply lead 20 of the port 16 for moving the piston towards the frame member 13, the fluid in advance of the movement of the piston exhausting through the port 15, its supply lead 19 and thence to atmosphere through the ,7.0
control valve. A valve 2l, in the main supply lead 18, is provided for interrupting the ilow of steam ,to `said ncontrol valve.
Intermediate the control valve 17 and the valve 21 there is shown a lubricator, generally indi- 75 Vcated at L, through which steam is passed, there v26 is in its lowermostposition, as shown in Figure 2. The lower portion of the valve' 26 is received by the bore 28"inimediately beneath and in communication with the auxiliary reservoir 24, the 9i upper portion of said bore 28 being provided with a seat 29 which receives a` complementary portion 30 `of the valve 26 for preventing the quantity of oil in the main reservoir 23 from entering the main steam lead 18 except when so desired. It is 95 apparent that the cylindrical portion of the valve 26, immediately beneath the complementary portion 30 must rst move beyond the seat 29 before oil from the auxiliary reservoir 24 will pass into the chamber 31. In the meantime, the cylindrical portion of the valve 26 immediately above the bevelled edge 30 will enter the cylindrical bore 25 and prevent the flow of additional oil into the auxiliary reservoir 24.
` Beneath the lowermost portion of the valve 26 105 is a chamber 31, which receives steam from the main `lead 18 through the pressure fluid intake port 50 when the Valve 21 is opened, for raising the valve 26 against the tension of the spring 32 which normally seats the valve inthe position shown in Figure 2. When the valve 26 is raised, steam will enter the pressure fluid discharge port 33 and then pass through the control valve for operating the piston 11.
In the operation of this device, it will be understood that the piston 11, the control valve 17 and the lubricator valve 26 are in the position shown in Figures 1 and 2, with the valve 21 closed. Whenever it is desired to actuate the piston, the valve 21 is opened, allowing steam to enter the chamber 31 of the main body member 22 causing the valve 26 to raise, thereby preventing further entry of oil from the main reservoir 23 to the auxiliary reservoir 24 and allowing the oil in said auxiliary reservoir 24. to pass through the grooves 34 of the valve 26 into the bore 28. The oil is then carried by the steam to thecontrol valve 17, the oil saturated steam passing through the supply lead 20 and its port 16 intothe cylinder 10, thoroughly lubricating the walls thereof. The control valve 17 is then raised to its uppermost position, allowing steam to enter the supply line 19 for moving the piston towards the ported head 12 along the lubricated walls of the cylinder 10, the steam in advance of the movement of the piston exhausting through the supply lead 20. When the control valve is lowered, the piston returns to the position shown in Figure 1. The valve 21 is then closed, which allows the pressure in the supply leads to diminish, permitting the spring 32 to return the valve 26 to its normal position. In practice, the supply leads are provided with suitable drains which open when the valve 2l is closed, thus allowing the valve 26 to be returned to its normal position almost immediately due to the rapid decrease in pressure in the leads.
The top wall 35 of the lubricator ybody member is threaded to receive a plug 36 for closing the opening 37 through which the valve 26 and the spring 32 are inserted in their proper relation. The plug 36 is provided with a passage 38, so that rair which is displaced by the upward movement of the valve 26 may escape. The upper po-rtion of the valve 26 is provided with a stem 39 which arrests the further upward movement of the valve and also closes the passage 37. The supply of lubricant may be replenished by removing a screw plug 40 in said top wall 35.
