Description
UNITED STATES PATENT OFFICE.
JOHN KELLY, OF CHICAGO, ILLINOIS.
PISTON-RING.
To all w hom it may concem Be it known that I, JOHNVKELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented a new and useful Improvement in Piston-Rings, of which the following is a specification. n
My invention relates, more particularly, to piston-rings provided between the piston and .the cylinder in which it reciprocates, for effecting a tight sealing joint between these parts, and more especially to structures of this kind wherein the rings are provided as a plurality of parts, each of split form, with the split portions of adjacent rings in staggered relation to prevent the formation of a passage-way from one side of the ring to the other. v
My object is to provide a novel, simple and economical construction of piston-ring which shall aiord the desired degree of resiliency, the sections of which are held against relative rotation and the structure as provided be strong and durable.
"Referring to the accompanying drawinfr:-
ITigure 1 is a view in sectional elevation of a cylinder and piston therein with a pistonring constructed in accordance with my 1nvention interposed between the piston and cylinder. Fig. 2 is a plan view of the ring shown, a section of the upper ring-section being broken away to disclose the gap in the lower ring-section. Fig. 3 is a perspective view of certain of the elements of the ring of the preceding figures for holding the main sections of the piston-ring against relative rotation, these elements being/shown in the positions they occupy relative to each other in use. Fig. 4 is a similar view of va modification of the structure of Fig. 3. Fig. 5 is a perspective, broken, view of' the split portion of one ring and the adjacent portion of the elements which prevent relative rotation of the ring-sections, these parts being shown in disassembled, but related, position; and Fig. 6, a similar view of the other ring section and the adjacent portions of the said elements.
In accordance with the y'referred embodiment of my invention, t e piston-ring is formed of two ring-sections 7 and '8 of springy material, preferably cast iron; these sections being of the same construction and split crosswise, as indicated at 9 and 10, re-
Aerably Specification of Letters Patent. Patented N0v 3()9 1920. Application led May 1, 1919.
Serial No. 293,930.
spectively, .each of these ring-sections having one split portion. Coperating with the ring-sections which, when assembled with the piston, as for example that shown at 11 and working in the cylinder 11a, extend sideby-slde, and with their gaps 9 and 10 at diametrically-opposite sides of the ring, are. according to the showing in Figs. 2, 3, 5 and 6, curved members 12 and 13 each slightly less than a half circle, these members extending in end-to-end relation, as shown in Figs. 5'and 6, and lying against the inner peripheries' of the ring-sectlons 7 and` 8 being interposed between these ring-sections and the bottom wall of the roove 14 in the piston-wall in which the plston-ring is located. The members 12 and 13V are each prefof a width equal to the combined width of the ring- sections 7 and 8. The members 12 and 13 at certain of their adjacent ends have outwardly-extending ears l5 and 16, respectively, of substantially onehalf the width-of the ring-section 7, which extend into the gap 9, and these members have outwardly-extending ears 17 and 18, respectively, at their other adjacent ends, likewise of substantially one-half thevwidth of the ring-section 8, which extend into the gap 10. The result thus produced is that while the ring- sections 7 and 8 are permitted to fit closely together, they are prevented from rotating relative to each other in the reciprocations of the piston, and thus the gaps 9 and 10 are maintained at all times out of registration with each other.
While I have shown the two members 12 and 13 for performing the function stated, it will be understood, that, if desired, one only of these members needbe used, the other being omitted. Furthermore, and as an illustration of another of the many modifications that may be made, the sections 12 and 13l instead of being formed of separate strips of metal, may be constructedl of a single strip, as shown in Fig. 4, to provide the projections at opposite sides thereofand `at opposite sides of its median line as explained of the structure of the preceding figures, to extend into the gaps 9 and 10 of the ringsections 7 and 8.
What I claim as new and desire to secure by Letters Patent is:
1. A piston-ring comprising a plurality of ring sections split crosswise, "anda curved member located at the inner periphery of the ring and having cutaway ends the uncut portions of its ends being of approximately onehalf the width of the ring-sections and upset to form outwardly extending projectionsto extend into the oppositely disposed spaces between the ends of the ring sections for holding the same against rotation. y
2. A piston-ring comprising a plurality of ring-sections split crosswise, and a curved 10 one piece member located at-the inner pe-4 ripheryof the ring and of substantially ci`rcular form with cutaway portions intermediate of and at its ends, the uncut portions being upset to form outwardly extending projections toextend into the oppositely disposed spaces between the ends of the ringsections for holding the same against rotation.
JOHN KELLY.
