CHARLES D. STEVENS, OF BROOKLYN, NEW YORK.
METALLIC ROD-PACKING SPECIFICATION formingpart of Letters Patent No. 271.748, dated February 6,1883.
Application filed November -28, 1882. (No model.)
To all whom it mayiconcern Belt known that I, CHARLES D. STEVENS, ofthe city of Brooklyn, county of Kings, and State of New York, have invented a new and useful improvement in metallic rod-packing for stuffing-boxes for piston-rods of steam-engines and like purposes, of which the following is such full, clear, and exact description as will enable others skilled in the art to which it mostnearly appertains to make and use the same, when taken in connection with the ac companying drawings, in which-- Figure l is a vertical section through a packing-box and my improved packing. Fig. 2 is a horizontal section through the same at the line as a ofFig. l.
Thepackingis formed offour separate'rings, A B G D. The ringB is made of a triangularor wedge-shape cross-section having its base outward and its apex inward. The outside of the ring fits against the inside of the packing-box.
' Thering D is made also of a triangular or wedgeshape cross-section, having the base of the wedge inward against the piston-rod, and of such a size that the apex of one ring will meet that of the other when they are placed one-within the'other. The rings A and U are each made of a triangular or wedge-shape cross-section and ot'such a size as to fit between the ring D and ring B when so placed that theapex of each will be toward the apex of the other. The four rings are so placed that they fit together and [ill a square or oblong space in their cross-section. The extreme of the angle at the apex of each is cut off andalso the other angle of the rings D and B. The rings,
each been cut into half or quarter circles, are provided on topwith a piece of elastic packing, H, preferably, although this may be being placed in a packing-box, after having quired by the size of the box and the rings,
The box having been filled'with sets of rings A B O D, a packing, H, is put on, and the head Gr screwed down, when it will be found that the packing has been made tight.
The advantages that this form of packing has over any other is that the pressure of the triangular rings A and 0 against therings and D causes both edges of the rings-B D to press against the'rod, and the same pressure is maintained when the rod moves in one direction as in the other. So soon as the pressureot' the ring I) against A stops by the change inmlhe motion of the rod it is forced against 0 with equal force, as the angles of the rings A'and U are equal.
What I claim as new, and desire to secure by Letters Patent, isr 1. The combination, in metallic rod-packing,
of an outside ring having a triangular crosssection, an inside ring having a triangular cross-section, and two triangular rings inter-
