LUBRICATOR.
SPECIFIGATION forming part of Letters Patent No. 695,603, dated March 18, 1.902.
Application led May 26, 1900. Serial No. 18,152. (No model.)
T0 all whom, it may concern:
Beit known that I, GREEvz FISHER, a British subject, residing at Leeds, in the county of York, England, have invented certain new and useful Improvements in Lubricators, of which the following is a specilication.
This invention relates to spring-controlled or spring-actuated lubricators in which a stilf lubricant is discharged by the action of a piston operated by a spring and is designed to reduce the variation of pressure consequent upon direct-acting spiral compressionsprings. By this invention I employ the combination of springs arranged so that the pressure produced by them is approximately constant upon the grease in the cup, the springs being attached or connected to levers so placed that when the spring is exerting its maximum force the leverage will be least and as the force or tension of the spring is grad;
ually relaxed the leverage will increase.
The invention Vwill be fully described' withk reference to the accompanying drawings, in which, as anexample, one form of piston-1w bricator is illustrated.
Figure l is a frontelevation of the invention applied to the piston-rod. Fig. 2 is a side elevation of same.. Fig. 3 is a transverse section. Fig. 4 is a plan. Fig. 5 is a detail of parts showing relative positions of levers and spring when latter is extended.
The lubricator-cup A, the piston B, the piston-cup C, and the spring D are of the Iordinary construction.
The piston B has hitherto been forced by the spring D, and I now apply the levers E E and springs F to the piston-rod G in addition to the spring D.
Above the piston B, by which the lubricant is discharged, I mount a double pair of levers E E, pivoted together at their ends by the pivots or pins e e. There` are thus four levers with four pivots pivoting or` connecting them together. The levers -E E are arranged in two s etsone set at one side of the piston-rod G and the'other set placed at the other side of the piston-rod, (see Fig. 1,) the two sets being connected together by the cross-blocks H, lwhich are `formed with holes which lit over and slide upon the piston-rod or through which the lpiston-rod is free to slide.
The levers EE are connected to the crossblocks I-l H by the top and bottom` pins e e', and between the pins4 lor pivots e e are stretched the springs F. The two side pivots are thus drawn together by the spiral springs F, the action of the springs andthe levers forcing the top and bottom pivots ee apart.
When the two cross-blocks II H' are brought nearly close together, (see Fig. 5,) the two pivots eA are at their farthest distance apart and the springs F are exerting their greatest force, but as the levers E E are nearly in a straight line the force of the springs is exerted to the least effect to force the pivots c c apart.
The lower cross-block H rests upon a nut shoulder or projection K on the piston-rod or may be attached thereto, and the upper crossblock II rests against a bracket L, rigidlyattached to the lubricator-top, so that the force of the springs F is directed to force the pistonrod and piston downward. Instead of. duplicating the parts of the ap paratus a single spring` may be placed in a central position, but for practical purposes the apparatus is better arranged as shown. It will thus be seen that the levers act at an increasingly disadvantageousleverage asy the two centralpivots ve e' arebrought to-k gether and the force exerted by the springs F is increased. I find that a much greater effective pressureis exerted thereby when in t the'position shown in Fig. 2 than when in the position shown in Fig. 5, and this is counteracted and a uniform pressure obtained by the'internal spring D, which in the position shown in Fig. 2 is exerting less pressure than in the position shown in Fig. 5;
What I claim as my invention, and desire to protect by Letters Patent, isf- 1. A lubricator for forcing sti lubricants comprising in its construction a piston, levers attached to same, one set of springs to actuate the piston attached to the levers which :ich ab an increasingly disadvantageous leverage as the force of the spring is increased in combination with a direct-acting spring, compressed between the piston and the oilcup lid, substantially as described.
2. In a, lubricator for stiff lubricants the combination With the lubrcator-cup A, the
the springs F placed between them, substan tally as described. Y
In Witness whereof I have hereunto signed my name in bhe presence of two subscribing witnesses.
