PISTON RING Filed July 26. 1930 llllllllllllllil IM/wn to c Wr/esel 676060 Patented Aug. 1s, i931 UNITED STATES J. GLEASON, 0F AUGUSTA. GEORGIA i Applikation and :my te, 1930. semi-1ro. 470,935.
This invention relates to an improvement incpiston rings for use in` connection with the-pistons of combustion engines, steam engines, pumps, or pistons for any other purs pose, and has as itsprimay objectpto provide a piston ring which will be quick seating to walls of cylinders thereby obtainin g nearly perfefctcompression and after use and wear'will retain its-eilicincy and 'less l, likely to score or mar the walls of cylinder in which the piston, to which it is' applied, reciprocates.
This A invention also consists in 'certain l other features of construction and in the combination and arrangementof the several parts, to be hereinafter fully described, illustrated in the 'accompanying drawings, andv specically pointed out 1n the appended claim, it being understoodl ofcourse that minor changes may be made so long as they fall within the Ascope of the claim.
In describing my invention in detail, referenee will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the Several views, and 1n which: Y
, Figure 1 is a perspective view 'of one form of iston ring embodying the invention. 2A isa side elevation ofthe ring showninFigure 1. l v Figure`3 is a perspective view illustrating a 4modification of the invention). Figure 4 is a view in side elevation illustrating anotherfmodilication of ltheinvention.
Figure 5 is a view in side elevation illustrating another modification of the inventiona y Generellv speaking, the invention'eontemplatesthe road idea of a piston ring consisting of a plurality of mutually overlapping coils so ormed that the rin in its interior, can be made of one piece o metal.
In the embodiment shown in Fi 1 of the drawings, the ring which is in 'cated in general b the numeral 1, com rises two coils 2 Van these coils are joined, integrally, at one end, l'vlvha diagonally bent connecting portion 3. efree ends ofthe coils are '5o mdicated by the numeraltanditwill'be 4 comprising four overlapping coils 2, and
observed that the lfree end of each coil is diagonally formed so that it may occupy a slightl spaced position with respect to one side o the diagonal bend 3 as shown in Fi ures 1 and 2 o f the drawings, it being o 55 served that the ends 4 of the two coils are presentedto opposite sides of the diagonal bend l3. l 4
The embodiment shown in Figure 3 of the drawings is identical with that shown in Figures Land 2 and therefore like references are employedv to indicate the several coils of the ring and the individual ortions thereof. In this embodiment instea of two superposed or overlapping coils, the
comprises three overlapping coils, and the diagonal bend 3 will of course be'formed between the` relatively adjacent ones of the overlapping coils.A
Figure 4 illustrates a modification 'is identical with that shown in Figures 2 andf3= exceptthat in this embodiment the i rin'gvis, of greater thickness than even the ring in Figure 3, the rmgshownin Figure the connectingdiagonal nds 3 and diago'nal` free ends .4 as inthe precedin 'ligures Theembodiment illustrated inF1gure5 is identical with the embodiment shown in Figures 1 and 2 Aexcept that the enacting .sides of the ltwo coils 2 are formed, near the free ends of the'coils, with matching recesses 5 whichprovide lubricant grooves in which a 'sufficient quantity of lubricant oil mayaccumulate to properly lubricate the cylinder wall `and 'also the piston.
From the foregoing description ofthe invention it will be evident that ya piston ring constructed in accordance with the process thereof will be more eicient in preventingleakage of the explosive charge and likewise in -preventing leakage of oil past the piston head. It will also be evident that the piston ring constructed ,in the manner above described and `as shown in the drawp ingsk will possess greater strength than the ordinary piston ring, andthereforeY will not be as liable to become broken as is 4the ordinaryrng.
What I claim is:
A one-piece piston ring comprising overlapping coils connected by a diagona bend,- the mutually contacting sides of the coils 5 having matching recesses to provie lubricant grooves.
In testimony whereof I aix my signature.
CHARLES J. GLEASON.
