to lubricators for feeding a mixture of oil This invention relates more particularly and powdered graphiteto engine cylinders, pistons and valves and other bearings, and

its main objectsare to p'reventprecipitation, orsettling of the graphite and to maintain aneven mixture thereof with the oil in the reservoirs from which the lubricant is supplied to the hearings; to reduce the quantity of oil required for adequate lubrication and generallyto increase the efficiency and mprove the construction and operation :of

' lubricators of thisclass.

Referring to Fig. 1, whichshows the invention as embodied in a lubricator in which provision is made for compressing air to spray the lubricant as it is discharged therefrom, 1 designates the lubricant reservoir having a detachable top plate 2, which is formed with a filling opening and provided with a removable cover 8, for the; opening,"

The pistons orplungers are connected in correspondlng pairs with yokesll, fitting The pumpv cylinders -7, which are ,sup

portedand guided by one or more hangers gor brackets 12, attached with the co npressor cyl1nders'8,to the topplate 2, are

adjustable axially toward and from the cam shaft, to ffvary the effective strokes of the pl-ungers 91. and the quantity of lubricant forcedv thereby from the barrels 7. The bar? rels 7 are adjusted by means .oflscrew rods 13, swiveled at their lower'ends in plates 14,

The pipe 30, which leads into the lower part ofthe reservoir 1, for agitating the lubricant contained therein, connects With the valve chamber below the valve 31. A plunger 35, guided and provided with packing in the lower end of the valve case,

tension of'its spring for intermittently admitting compressed air into the pipe 30. A rack 36, guided in a casing or body 37" in I axial alinement with the plunger 35, meshes with a pinion 38 on a rocker shaft, which is providedwithan arm 39, for connecting it with an engine or. other machine, and imparting an oscillatory movement to the' pinion. An adjusting screw 40, threaded in the upper end of the rack 36'and fastened in adjusted position by a lock nut 41, affords means for varying the liftor opening of the valve .31, and hence the quantity ofcompressed air admitted to the pipe 30'and the 1 volume and strength of the air puffs discharged into'the lubricant in the reservoir 1. This form of lubricator is providedwith force feed mechanismandconnections (not shown) for taking the mixed lubricant from the reservoir 1 and delivering itto the cylinder of an engine or tothe bearings of amaQ chine with which the lubr cator is conj nected. p

The operation of the compressed air agitator in this form of lubricant is inv effect the i same as that shown in Fig. 1. With the-0s cillation of the pinion 38, the rack 36 is reciprocated, and in its upward movement thrusts the plunger 35 upward against the weighted ballvalve 31, momentarily lifting it from its seat against the tension of its spring. A quantity of compressed air determined by the adjustment of the screw a0, is

thus admitted to the pipe 30, causing a sudden puff of air to be discharged from its lower end into the lubricant contained in the reservoir 1. As the rack 36 is moved downward-out of engagement with the plunger .35, the plunger is forced by the compressed air back to its initial position, and the ball valve 31 isclosed by its spring. These operations being repeated at frequent and regular intervals, the graphite is kept thoroughly mixed with and evenly distributed throughout the ,oil contained in the reservoir 1, from which it is drawn and delivered as required by the feed mechanism and connection or connections to the parts or bearing thecover 3 and pouring the oil an graphite through the strainer 4.

Various changes in the construction and bodied in lubricators of different kinds for different purposes, may be made'without departure from the principle and scope of the invention as defined in the following claims. is adapted to open the valve 31 against the i Iclaim; f- I t 1. In-a lubricator the combination of a lubricant reservolr and means for dehvermg a gas such as air inisuccessive pufl'sinto a I fluid lubricant contained in the reservoir.

2. In a lubricator the combination .with a lubricant reservoir'and means for feeding lubricant therefrom to a bearing, of means for introducing a gas in successive puffs into a-fluld lubricant contalned 1n the reservoir. 3. Ina lubrlcator the 'comblnatlon of a lubricant reservoir, a compressed air conduit leading into sald reservolrbelow the normal] level of the lubricant therein, a

weighted valve normally closing said conduit, and meansfor intermittently opening sor having a reciprocating plunger for forcing air throughsaidconduit into lubricant contalned 1n" the reservolr, and a weighted valve in said conduit opening toward the i reservoir.

5. In a lubricator the combination of'a I g lubricant reservoir, a compressed air conduit opening into the lower part of the reservoir, a compressor having a reciprocating plunger for compressin andforcing air in successive puffs into, lu r the reservoir, a weighted valvevin said conduit opening toward'the reservoir, and a pump connected with the compressor for supplying a limited quantity oflubricant thereto for lubricating r and sealing its plunger. I

6. In a lubricator the combination with a lubricant reservoir, a compressed air conduit leading into the reservoir, a weighted valve opening in'said conduit toward the reservoir, means for successively openmg said valve, and a test cockbetween said valve and the discharge end-of the conduit having a vent to the atmosphere and adapted to open the vent and close the conduit be tween the vent and reservoir and to close the vent and open the conduit.
