LEOPOLD KATzENsTEiN, OF NEW YORK, N. Y;
Specification forming part of Letters Patent No. 135,127, dated January 21, 1873.
To all whom it may concern:
Be it known that I, LEOPOLD KATZEN- srEIN, of New York city, in the county and State of New York, have invented a new and Improved Packing for Piston-Rods, Src., of which the following is a specification:
Figure 1 represents a central longitudinal section of my improved packing. Fig. 2 is a side view of the same. Fig. 3 is a face view, and Fig. 4 a 'central section ot' one of the rings.
Similar letters of reference indicate correspondin g parts.
This invention relates to improvements ofthe packing described in the Letters Patent No. 105,462. and dated July 19, 1870. The object of the present invention is to insure the proper adjustability of the rings and also to facilitate their insertion within and removal from t-ho packing-box. The invention consists in formingthe cut rings with spaces between the ends of their several sections, and also in providing them with screw-sockets to permit the application of screwrods for the insertion and removal of the rings.
A in the drawing represents the packingbox; Bfthe rod to be packed. C, D D, E E, and F F are the packing-rings, which, 4together with the spring or cushion G, till the annular space between the rod B and the inner surface of the box A. The form of crosssection of these rings is fully apparent from Fig. 1. The middle ring C is inclined on opposite sides. The rings D D contiguous to it are at, but placed obliquely against the inclined faces of the ring C, respectively. The rings E E contiguous to D D have double inclined faces,
which converge toward the rod B, while on the ring C the inclined faces diverge the more they approach thexrod B. The end rings F F have each one face inclined parallel to the contiguous rings E, and one parallel with thc bottom or end ot' the box A, or nearly so. Each of the several rings is cut so as to cousist of two equal pieces, as shown in Figs. 3 and 4. In cutting them sufcient material iscut away to leave the sections of one ring clearly apart from each other, to make allowance for contraction during the wearin g ot the rings or rod. At their outer edges the rings are reduced by trimming off their corners, so as to leave small annular spaces or grooves a a between them, as shown in Figs. l and 2. In these spaces a the steam which leaks through the packing collects and condenses, and serves as an embracing cushion for the rings, thereby aiding in the efficiency of the packing. Each section of ring has in its upper facei. e., in the face which is placed toward the open end of the box A-a screwsocket, b, for the reception of a screw-rod, H, as shown in Fig. 4. Without such rods the rings cannot be conveniently applied, much less removed; the screw-sockets are therefore of importance.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The packing-rings C D E F having screw sockets b and arranged to form grooves a, in combination with rods H androd B, all construct-ed as and forthe purpose set forth.
LEOPOLD KATZENSTEIN.
