Application filed March 9, 1907. Serial No. 361,439.

To all whom "it may concern:

Be it known that I, JACOB Sonss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Mechanical Lubricators, of which the following is a specification.

This invention relates to mechanical lubricators and is especially adapted for use on automobiles and other high speed machines.

The object of the invention is to provide a mechanical lubricator of simple construction and few parts in which the oil is delivered in quantities as required to a plurality of feeds by a single pump.

The invention has other objects in View which will appear hereinafter in a detailed description of the drawings which show one embodiment of the invention and in which Figure 1 is a sectional elevation; Fig. 2 is a sectional view on the line 22 of Fig. 1 Fig. 3 is a detail sectional view Figs. 4 and 5 are sectional views on the line 44 of Fig. 1; Fig. 6 is a detail sectional view.

Referring to the drawings in which like numerals of reference designate corresponding parts in the several figures, 7 is an oil reservoir of suitable size and sha e within which the pump mechanism is inc osed. A drive shaft 8 is j ournaled in a wall 7 of the reservoir and in a standard 9 within the reservoir and this shaft carries a pulley 10 outside of the reservoir and a pinion 11 within the reservoir. The pinion 11 meshes with a gear 12 arranged within the reservoir on a stub shaft 13 supported on the wall 7 of the reservoir. A disk 14 is fastened to the gear 12 and is provided with a groove 15 and a collar 16. A piston 17 is arranged to operate in the pump cylinder 18 supported within the reservoir and this piston has on its u per end a rectangular frame 19 provided wit 1 inturned side flanges 20 which operate in the groove 15 (Fig. 3). The disk 15 carries a wrist pin 21 which operates within a frame 21 on the lower end of a plunger 22, the latter projecting upward through an opening 22 in the frame 19 and an opening 22 in the reservoir and carrying a spring 23 which is confined between the top of the frame 19 and nuts 24 on the outer end of the plunger. The pump cylinder is provided with a tubular extension 25 at its lower end which has an inlet opening 26 normally closed by a ball valve end of the extension 25 and to a bore 31 which forms an oil distributing channel in the casing 32 and communicates independentlywith each of the valved feeds. Each of these valved feeds comprises an upwardly inclined passage 33 leading from the distribut ing channel 31 to the seat 34 of the valve 35 carried by a regulating screw 35-, this seat being located at the upper end of a passage 36. The screw 35 operates in a boss 37 on which a cap 38 is screwed. A plunger 39 is arranged in a chamber 40 in the valve casing 32 below the passage 36 and this plunger is normally held in the position shown in Fig. 5 by a spring 41 located between the end of the plunger and an adjusting screw 42 in one end of the chamber 40. The plunger carries a rod 43 which projects through an opening 44 in the valve casing and is provided with a handle 45 of any suitable character. The inner end of the plunger is provided with an angularly disposed channel 46 which receives the oil from the passage 36, when the parts are in the position shown in Fig. 5 and permits it to flow therethrough into the chamber 40 and thence to the ni ple 47 whence it is carried to the parts to be lubricated. The plunger is also provided with a bleeder groove 48 which forms a communication, when the parts are in the position-shown in Fig. 4 between the passage 36 and a passage 49 in the valve casing below the chamber 40 and discharging through a sight chamber 50 and an opening 51 into the reservoir. The sight chamber is located in the part which has been generally referred to as the valve casing and beneath the plunger 39 and it is provided with a glass front 52. It will be understood that all of the feeds are similarly rovided with the parts hereinbefore descri ed and illustrated in Figs. 4 and 5 and that the apparatus may be equipped with as many of these feeds as desired.

The operation may be briefly described as follows:Assuming first that it is desired to regulate the feed, the pump is started in operation and the plunger 39 is pushed inward until the bleeder groove 48 is alined with the passages 36 and 49.- The oilwill flow through the pipe 30, the distributing channel 31 into the passage 33 and passage 34 through the groove 48 and passage 49 and drip through the sight chamber 50 and opening 51 back into the reservoir. By observing the drops through the glass 52 and adjusting the screw 35 the feed can be regulated as required and in this connection it will be observed that each feed is separately regulated and therefore that the flow of oil in the several feeds may be the same or dill erent as desired. Then pressure on the plunger is released to permit the spring 41 to return the plunger to its normal position, as shown in Fig. 5, whereupon the oil flows from passage 36 through channel 46 and chamber 40 to the feed nipple 47. To operate the pump power is applied to the shaft 8 whereby the gear 12 and disk 14 are revolved. The wrist pin reciprocates the plunger 22 and the pressure of the spring 23 operates the piston 17. The

v'rist pin operating in the frame 21 reciprocates the plunger 22 and on the upward stroke of the plunger the frame 21 engages the frame 19 to raise the piston 17. hen the wrist pin proceeds on its downward stroke carrying with it the plunger, the spring 22 is compressed by the resistance of the piston and by expansion operates the piston in a downward direction. The pump sucks in the oil from the reservoir through open ing 26, unseating ball valve 27, and forces the oil from the cylinder 18 into delivery )ipe 30 by unseating the ball valve 29, the ball valve 27 being seated during the delivery stroke of the pump. The supply of oil delivered by the pump is regulated by spring 23 to avoid exceeding the amount of oil required because the spring will notoperate the piston when theback pressure on the piston is greater than the expansive pressure of the spring.

As the passages 33 leading from the distributing channel to the valve seats 34 are inclined upwardly the oil will be prevented from wasting when the pump is not in oper ation. The-nuts 24 on the plunger 22 can be adjusted as required to provide the proper pressure for operating the pump piston.
