ERNEST ARMSTRONG AND CHARLES M. SIEFKEN, CF CAMDEN, NEXV JERSEY.
DESIGN FOR A PACKING-RING.
SPECIFICATION forming part of Design No. 28,198, dated January 18, 1898.
Application filed December 16, 1897 Serial No. 662,227. Term of patent 3% years.
To (0% whom it may concern.-
Be it known that we, ERNEST ARMSTRONG and CHARLES M. SIEFKEN, citizens of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented and produced a new and original Design for a Piston-Rod Packing-Ring; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part thereof.
Figure 1 is a perspective view of our new design. Fig. 2 is a sectional View of Fig. 1.
As shown in the drawings, the leading or essential feature of our design consists of a ring having outside surfaces which diverge from the ends of the ring-opening and converge together out of the central transverse plane of the ring. The ring-opening A is straight through the ring. The curved surface B diverges from one end of the opening A, and the curved surface C diverges from the other end of the said opening. The surfaces B and C converge together or into each other at D, which is out of the central transverse plane of the ring, as clearly shown in the drawings, thus forming the outer surface of differently-pitched curves, which gives the effect of a semicircular ring, yet in cross-section, as shown in Fig. 2, the exterior of the ring is formed by a compound curve.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
The design for a piston-rod packing-ring, as herein shown and described.
In testimony whereof we afflX our signatures in presence of two witnesses.
ERNEST ARMSTRONG. CHARLES M. SIEEKEN.
