UNITED- STATES LOUIS NAGY, .OF ESTERHAZY, SASKATCHEWAN, GANAI- msron-mno.
Specification of Letters Patent. Pate 11 Sept. 13, 1921.
Application filed ma 10, 1920, Serial No. 380,437.
To all whom it may concern;
Be it known that I, LOUIS NAGY, a subject of the King'of Great Britain, and a-resident of Esterhazy, in the Province of Saskatchewan, Canada, having invented certain new and useful Improvements in Piston-Rings, do hereby declare that the following is a full, clear, and exact description of-the same.
My invention relates to piston rings and especially to that type known as leak-proof wherein the joint is of such construction that the escape of gas is prevented from passing therethroug The construction of my ring will be better understood by referring to the accompanymg drawings in which slmllar'symbols of. reference refer to similar parts throughout the different views and in which Figure'l is-an outside view of the portion of the ring showing the joint" as seen' from the outside. 1
ex anded.
. Referring to Fig. 1, 1 is an extension of portion B, of the ring extending and overlapping a corresponding extension of por-- tion A of the ring as shown in Figs. 2, 4, 5, 6 and 7. 3 is a second extension of portion B-of the ring engaging a groove 4 as shown in Figs. 6 and 7. 5 is the end of portion B of the ring abutting with 6, being the end of portion A, such as shown in Figs.
the same depth thereof.
3, 4, 6 and 7. Inside of the ring, an extension of portion A at 7 corresponding to the extension 3 on the outside of the ring, engages a groove 8 as shown in Figs. 3, 4 and 7. When in use, the ring is placed so that itstop, as described in the drawing, is against the pressure of the gas, so that there will be no opening for the gas to enter be.- hind the ring, the slit 9 of the ring being closed by the extension 2. In the case where gas entering the slit 9 and escaping between the portion 3 and the groove 4, the end 6 of the ring at 10 will prevent this. This is very important as rings wear somewhat quicker on the ends, and consequently, the surface of extension 2 and 1 would separate to a certain extent and the gas, unless prevented by portion 10 of the ring, would leak around the piston. It will be noted that the ring reta ns its strength even at the joint as the ends 5 and 6 are the full depth similar to the remainder of the ring. By referring to Figs. 4, 5- and 6, it will be easily seen that the ring can expand to a large extent and I still no. passage is opened for the gas under pressure.
-' I claim Ina piston ring, a joint, formed of overlapping counterparts, dividingthe ring ends widthwise in three equal longitudinal sections. forming, a bottom section having a flush abutment the full thickness of the ring, a central section having a'tongue extending Well beyond the bottom section and over-half the thickness; of the ring and a central notch in-the ring extending well backof the tongue, an upper section having cut-away portions extending half the length of the central notch portion and of LOUIS NAGY.
