D. M. SOLENBERGER PISTON RING Filed Dec. 31, 1925 w@ www lo not the ring interferes With nieren nnte. i
implication led lleeember 31, 1925'.
The invention relates to sealing rings of that type in which the ringis rendered bothanially and radially expansible respectively y circnnn'erentally slotting and transplitf tin 9".
p with such constructions some diicudlty has been experienced in the formation of a satisfactory joint between the split ends of the ring. lt is therefore.. the object of the present invention to obtain a joint avoiding such defects and to this end the invention con--v s1sts in the construction as hereinafter vset forth. 1 f
,ln the drawings: f
' Figure l., is a side elevation ,of a piston ring shown as developed into a single plane. Figure 2 is an enlarged side elevation of one construction of my improved joint.
Figure'B is a planview of the ring the rind groove.
llignre el is a sectional perspective view.' i and 6 show Figures 5 structions.
then longitudinally slotted preferably with overlapping slots l and C to impart thereto axial resilient compressibility. Thu s,'when the ring is inserted in its groove D axial tension is exerted suiiicient to maintain sealing contact With the side walls of said groove and to conform to any irregularities therein but limited so as not toV produce excessive Wall friction. lt is, however, desirable to increase the radial Aexpansion pressure of the ring by the use of a supplementary expander such as E which may be formed of a corrugated resilient metal ribbon inserted between the inncr face of the ring and the bottom of the ring groove.
As previously stated, difiiculty has been encountered in providing such a ring with a satisfactory joint. First because the slotting the usual lap construction, and secondly because the friction of the expander holds the ring from ro tation so that any gap between the ring ends is likely to cause the Wearing of a ridge in the cylinder Wal I have,'however, avoided such diliculties by-tlie following construction* As shown in liigures 2, 3 and t the ends of the ring on opposite sides of the split are fashioned to form overlapping portions 'axial resi i are shown. inodiied Joint conu semi ne. 78,87?.
which are of triangular cross section and which torni complementary portionsof the full recta llar cross section of the ring.
heee portionsll and G are also slotted for iency but the slots the respective ends are indifferent p s a consequence each of these slots `is sealed by the overlapping triangular portion of the other end as illustrated in Figure 4:. Fur# therniore, each of these slots B and C passes through the thicker portion of the triangular cross section thereby avoidin the forining 'of a Weak member that' mig t be by avoidingthe wearing .of a groove in cylinder Wall. Y
in Figures 5 and (modied constructions Figure 5 shows a simple lapped Jointformed by the ragbbets I I and tongues J5. In Figure 6 the sp it .between the ends of. the ring is oblique so be an overlapping of such ends even when the ring is fully expanded radially. Both of ese constructions will therefore avoid the Wearing of a ridge in the cylinder.
ln all of th thering A is slots B', C extending different planes instead of being arranged in the same plane. Also, these slots are less than one-half the length ofthe other slots shortening the cantilever preferab y so slotted that the opposite end portions are symmetrical.
What I claim as my invention is:
l. 'In a trans lit sealing ring circumferentially slotted or axial resiliency, a joint lformed by end OrtiOns'haViDg'the slots therein arranged 1n different planes.
ln a transplit sealing ring circumferentially slotted for axial resiliency, a joint formed by overlapping end portions slots therein arranged in dillerent planes.
3. ln a transplit sealing ring circumfereny.
tially slotted for axial resiliency, a 'ont formed by overlapping end. portions o triangular cross section ormmg complemem.
tary portions' of the` full rectangul section.
e. In a transplit sealing ring that there will e' constructions above described to the ends are in having the l tially slotted for axial resilieny, a g'oixit;
'ox'meflby overlappingend portions oi trilsingular cross lsection forming complemem taiy portions of the full rectangular Cross section the slots in said end portions being in dierent planes and in the thicker portion of he cross section'.
a 5. In avtransplit sealing ring circumferentmlly slottedv for axial resiliency, a joint formed by overlapping end poi-tions which 10 are symmetrical in tension.
In testimony whereof I alix my Signature.
