Title: Improvements in lubricating apparatus, more particularly for lubricating the cylinders of reciprocating engines
IPC: F16N13/10
Filed: 1927-05-06
Abstract: 295,418. Wygodsky, L. May 6, 1927. Two or more barrels in series; actuating by fluid pressure; nozzles, arrangement of.-Lubricating apparatus for engines comprises a cylinder 25<1>, Fig. 4, into which oil is forced so as to displace a piston 21, the latter, after a predetermined movement, operating means causing the piston to move in the opposite direction so as to discharge a portion of the oil to the part to be lubricated and simultaneously to discharge the remainder to the source of supply. A pump 15, Fig. 5, actuated by rack-and-pinion gearing 60, 61 from a shaft 62 having an arm adjustably connected by a rod 73 to a bracket 45 connected by links to the engine valve mechanism so as to be swung about pivots 71, draws oil from a reservoir 12 and discharges it to the cylinder 25<1> on the inner side of the piston 21. The oil has access through a passage 30, Fig. 4, to a bore in a plunger 22<1> secured to the piston and through the plunger and valves 27, 76 to a delivery passage 6. The pressure of oil depresses the piston 21 until its rod 28 depresses a spring-pressed trigger 33 mounted on a lever 36, so that the trigger is caused to engage a tooth 49 on the bracket 45, whereby the lever is raised into the position shown in full lines in Fig. 5. A block 50 on the lever raises a spring-pressed valve 38, thereby opening the inner side of the piston 21 to the reservoir 12 through a passage 40, and also raises a plunger 70. The latter is thus brought into contact with a part 68 of a spring-pressed valve 42, thus cutting off communication between the outer side of the piston 21 and the atmosphere through a passage 39 in the plunger 70, and the subsequent raising of the valve 42 opens communication between a passage 69 leading from the outer side of the piston and a passage 43 connected to a source of compressed air or the like. The piston 21 is thus moved inwards, expelling oil from the cylinder to the reservoir, but oil trapped above the valve 27 is dicharged at high pressure into the delivery passage 6. On the return movement of the bracket 45, the trigger 33 is released and the lever 36 returns to its normal position, the valves 38, 42 closing and the outer side of the piston being again put into communication with the atmosphere. In a modification, the pump 15 is operated by steam pressure drawn from the engine cylinder. As applied to the lubrication of an engine cylinder, the delivery passage 6 is connected to a nozzle 1, Fig. 3, mounted in the cylinder head 23. The nozzle contains a spring-pressed conical valve 3, Fig. 1, having a hollow stem provided with tangential holes 4 adjacent the seating surface, whereby the oil is discharged in the form of a hollow core 9 on to the cylinder wall near to the middle thereof and also lubricates the piston rod 25 at 11. The apparatus is so timed that discharge takes place when the piston 24 is at or near the dead point remote from the nozzle.
