LEE WHITCOMB, OF PLAI'NFIELD, ILLINOIS.
PISTON RING.
To all whom it may concern:
Be it known that I, LEE WHITOOMB, a citizen of the United States, residing at Plainfield, in the county of \Vill, State of Illinois, have invented certain new and useful Improvements in Piston Rings; 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 new and useful improvements in piston packing rings and particuIarly to piston packing rings for use on the pistons of explosive engines.
One object of the invention is to provide a piston packing ring of such construction that the same will insure against leaking past the piston whether placed with one end or theother uppermost, in the piston.
Another object is to provide a piston packing ring of this character whereby the use of pins for retaining the parts of the ring together is obviated.
Other objects and advantages will be ap parent from the following description when taken in connection with the accompanying drawing.
In the drawing: I
Figure 1 is a top plan view of a piston ring made in accordance with the invention.
Figure 2 is a bottom plan view of the ring.
Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 1.
v Figure 4 is a perspective view of the inner or base section of the ring, the upper and lower sections being removed.
Referring particularly to the accompanying drawing represents a split resilient spring ring which is thickest or widest at a point approximately 60 in one direction from the split 10 thereof, and thinnest or narrowest at a point diametricall opposite to the widest or thickest point. Formed in the center of the outer curved face'of the ring section 10 is a circumferentially extendingrib 11 which forms the upper and lower peripheral grooves or channels 12 and 13,

respectively thereabove and therebelow. It will be noted that, by reason of the ring section being wider at one point and thinner at the diametrically opposite point, that the upper channel 12 is shallower at the former point and deeper at the latter point. It
will also be noted that the lower channel 13 is shallowest below the point where the upper channel is deepest and deepest below the point where the upper channel is shallowest.
Seated in the upper channel 12 is a ring section 14 which is rectangular in cross section, said ring being split at 15, at a point adjacent the widest portion of the section 10, and having its widest portion at a point diametrically opposite to the split 15 and a point in one direction from the split 10 of the section 10. The ring section 16 .is seated in the lower channel 13 and is split, as at 17, at its narrowest portion said split being disposed at a point 60 fro-m the split in a direction opposite to that of the split 15. Y
What is claimed is:
A piston packing consisting of a split spring ring body having its thinnest portion at approximately midway between the split and a point diametrically opposite the split, and its thickest portiondiametrically opposite the thinnest portion, the outer peripheral face of the ring body being formed with an outstanding central rib which produces channels at opposite sides thereof, the channel at one side of the rib being deepest at the thinnest portion of the ring body and the opposite channel shallowest at such portion of the body, while the diametrically opposite portion of the first channel is shallowest at the thickest portion of the body and the other channel deepest at such portion, and rings in the channels.
In testimony whereof, I afiix my signature, in the presence of two witnesses.
LEE WHITCO'MB.
