A. FRYKMAN.
. PISTON RING.
APPLICATION FILED JULY 21.1916.
Patented Nov. 28, 1916.
" aeoo alarm-arises AUGUST FRYKMANL'OF scams, nonm-nnxorn.
PISTON-BIN G.
To all whom. it may concern Be it known that I, AUGUST FRYKMAN, a citizen of the United States, residing at Souris. in the county of Bottineai'r. State of North Dakota, have invented a new and useful Piston-Ring; and I' do hereby declare the following to be a full, clear; and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an improved exp'ansible piston ring, particularly adapted for use in connection with pistons and the like and at the ends of cylinders, to prevent leakage of steam or other expansive fluids.
An object of the invention is the provision of a piston ring ha ving separable ends, which are considerably less in thickness than a diametrically opposite portion of said ring. In other words. the wall of the ring tapers in thickness in opposite directions from a point diametrically opposite said separable ends. to said separable ends. thereby aii'ording means to cause the ring to expand against the cylindrical wall of the cylinder.
A further. object of theinvention is to.
provide the separable ends with sidewise overlapping parts and an inner cover plate underlying said sidewise overlapping parts. thereby affording a joint. which is steam or fluid escape proof.
A further object of the invention is to provide means upon one face of the cover plate engaging correspondingly shaped ,ineans upon the inner-face of one ofsaid separable ends, to force the sidewise overlapping parts closely together.
In practical fields. the details of construction may necessitate alterations falling within the scope of what is claimed.
The invention comprises further features and combination of'parts. as hereinafter set forth, shown in the drawings and claimed.
In the drawings: Figure l is'a view in perspective of the improved piston ring constructed in accordance with the invention. F ig. 2 is an enlarged detailperspective View of a portion of the ring. showing the sop.- arable ends-separated. Fig.3 is a perspective view of ap iston ring. showing-a modified structure for more closely connecting the separable-ends. Fig. his an enlarged detail perspective view of the separable ends joined, showing the structure illustrated in Fig. 3. Fig. o'shows the separable'end's that Specificationof Letters Patent.
Application filed July 21, 1916. "Serial No. 110,533.

1 designates the piston ring which isprovided with sepa able end portions 2 and-3.
Iatented'Nov. 2 ,1916.
The ring" at a point diametricallyopposite the end portions 2 and 3 is thicker than said end portions. In other words, from;
the'pointl a 'tl1e ring tapers; in thickness in opposite directions. as indicated by the ar-;
rows 6 and 0 toward and to the separable end portions 2 and 3. One side of the end por: tion 2 is provided with a recess or-cut away portion a; while the diagonally opposite side of the end portion 3 is provided-with a similar recess. or cut away' portion.
which diagonal opposite recesses or cutaway portions 4 and 5' receive the diagonal oppositely disposed tongues-6 and 7. which are caused to be fm-inedby constructing the re-' It is to be noted that the ally engage as In assist in preventing leakage of steam or the like. The inner face of the end portion 2 has forum} integrally therewith an extension cover plate 8, which of. 'suflicient length to imderlap the Sideing leakage of the steam or thelike. In
- wiseoverlapping tongues 6 and 7 and recesses 4 and 5. to further assist in prevent- F-igs. 3,- 4. 5 and 6. the inner face of the end portion 3 adjacent the recess 5 is provided with a groove 9-V-shaped in cross section,-
which is disposed at a slight, angle to the side. edge of the piston ring. This iangleor..
inclination is so infinitesimallyslight asjtov be hardly perceptible. and the-groovejs de- S12'I19tl to receive a correspondingly disposed rib 10. V-shaped ZlII-CIOSS section, on-the outer, face of the underlapplngcover plate, whereby as the. diagonally opposite tongues G-and- 7; entertheir respect ve diagonally opposite recesses 4- and the ad acent faces of. said- .tongues I and 7-will,so frictionallyand movably contact as to insure against any possithe head ofa cylinder. I The inventionlhavingbeen set forth,'wh at .isxclainied as new and useful is:'. An'expansible-piston ring having sepa? a l piston voradjacent 'ble. leakage of'steam or other fluid-.When the piston ring is in useon i-os rable free ends. said separable ends having diagonallyoppositerecesses adjacenttheir sides.' and provided wit-lr'diagonally, oppo-' site side toii'gues-toenter'said diagonally op- -posite recesses, whereby the tongues .w1ll
sideivise overlap each other, one of said ends having integral therewith on its inner face a cover plate of sullicient length to entirely overlap said diagonally opposite recesses and \5 tongues to insure against leakage, the inner face of one of said ends adjacent its respective recess having a groove at a slight in cline to the side edge of the ring, the outer face of said cover plate having a rib corre- 10 spondingly inclined and designed to enter said groove, to force the adjacent faces of the sidewise overlapping tongues, to so frictionally engage as to insure against leakage. In testimony whereof I have signed my name to this specification in the presence of 15 two subscribing witnesses.
