'PACKING RING.
APPLICATION FILED Ammo. 1915 l ,1 9 l ,276. Patented July 18, 1916.
CLARENCE ROSS BRYANT, 0F MEMPHIS TENNESSEE, A SSIGNOR TO NATIONAL ADVER- TISING COM PAN Y, OF MEMPHIS, TENNESSEE.
PAcKm-RING.
' To all whom it may concern Be it known that I, CLARENCE Ross B Y- ANT, a citizen of the United States, resldlng at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Packing-Rings, of
which the following is a specification.
This invention relates to packing rlngs or piston rings, the same being especlally adapted for use in COI1I1e0t10n W1tl1 the p stons of engines in general to produce a fluid tight contact between the piston and 1ns1de wall of the cylinder thereby obtaining better compression and higher efliciency and insuring against danger of leakage as the packing ring hereinafter described presents a practically continuous worklng face, leaving no opening or gap through wh1ch the fluid or pressure may escape.
With the above and other objects in vlew, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. In the accompanying drawings: Figure 1 is a plan view of a packing ring embodying the present invention. Fig. 2 1s a perspective view of the outer 'ring like member. Fig. 3 is a similar view of the inner ring like member. Fig. 4; comprises a series of detail sectional views, the sections a, b, and c, of Fig. 4 beingtaken respectively on the lines aa, 6-1), and cc, of Fig. 1; Fig. 5 is a plan view of a modified form of ring embodying the same principle. Fig. 6 isa perspective view of the outer ring memberof Fig. 5. Fig. 7 is a similar View of the inner r1ng member of Fig. 5. .Fig. 8 comprises a series of cross sections a, b and 0 taken respectively on the lines aa, 6-4) and cc of Fig. 5.
The packing ring contemplated in this invention comprises in each instance an outer ring-like member designated generally at A and an inner ring-like member designated generally at B.
The outer and inner ringmembers A and B are made eccentric tapering from-a middle point toward their extremities. In Figs. 2 and 3 the outer ring member A is shown as of approximately one half the thickness of the complete ring at its center and'made tapering therefrom to feather. edges at the points 10 while the rib 11 extending circumferentially of the inner face thereof is of uniform thickness throughout. urther,
' Specification of Letters Patent. I Patented July 18,1916, 1 Application-filed Auguist10,1915. Serial No. 44,786. 1
it will be observed that the inner ring memher is thickest at the middle thereof and made tapering to'ward'its extremities, the extremities 12 being approximately half the thickness of the complete ring and the middle portion 13 of the'member-B in F ig.;3 be.-.
'ing of the full width of the'complete packing ring. The member B is formedin its meeting face with a circumferential groove or annular recess 14: of the same depth throughout its length, the same terminating in feather edges 15 adjacent to the ends of the member B thereby forming'open ended slots 16 which-receive the projecting ends 17 of the outside ring member A of Fig. 2. The ring of Fig. 1 is of'uniform thickness as a whole throughout, the outer and inner faces thereof being described on concentric lines. Any. relative rotat'ive movement between the members A and B in Fig. 1 is prevented by the eccentric meeting faces of said members.
In Figs. 5 to 8 inclusive, another form of packing ring is shown, involving practically the same principle as disclosed in the preceding figures, the main difference residing in the fact that the outside member A has the rib 20 on the inner or meeting face thereof arranged in line with one edge of the main body of the ring as best shown in Fig. 6 while the inner member B has the groove or recess 21 thereof, which receivesthe rib 20 of the member A, ar
ranged adjacent to the opposite side of the complete ring. Each member A and B is therefore substantially L-shaped in cross section as shown in Fig. 8, the main body of the ring A tapering from its central and thickest portion at the point 22 to the feather edges 23, and the member B being also thickest at its central point 24 and tapering therefrom toward its opposite extremities so that the groove 21 terminates in the feather edges 25. v
Under each of the forms hereinabove described, the ring as a whole is of uniform gage or thickness throughout its circumferential extent or, in other words, the outer and inner faces of the complete ring are in concentric lines. Furthermore, in each form of ring, their meeting eccentric faces each serve to prevent relative rotative or turning movement of the ring section one upon the other. While the complete ring is of uniform thickness throughout itsentire extent, it is capable of readily. contracting and expanding equally and uniformly et all points, thereby maintaining perfect working contact with the inside wall of the cylinder in which it operates; thus insuring against lea'kageofsteem, gas or other fluid,
the outer face of the ring being practically continuous thus providing for retaining compression when used in internal combustion engines and obteiningthe highest efficiency of the engine. Furthermore, there is little or no liability of scoring the cyliinder Wall which frequently happens when a new piston ring of thepresent day type is placed in the piston, by reason of the thin projecting extremities of seidring.
. Having thus described my invention," 1 I claim 1. A packing ring embodying an outer split member eccentric in form, and an inner split member, the extremities of said members being out of line. a rib on the meeting face of the outer member, a flange on each side of the rib, said flanges beingof Copies ct this patent may he obtained for uniform width or the inner member terminating at their thinnest part short or the extremities of said rib, and the inner member being formed inits outer periphery in itsouter periphery with an annular recess extending to the extremities thereof to receive said rib.
in testimony whereof I aiiix my signature in presence of two witnesses.
