STEAM-PACKING.

SPECIFICATION forming part of Letters Patent No. 254,736, dated March 7, 1882.

' Application filed July 6,1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLEs M. VAN TINE, of Matteawan, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Steam -Packing, of which the following is a specification, reference being had to the accompanying drawings.

The invention relates to an improvement in steam-packing; and it consists in a metallic IO ring or band formed either in one piece or in sections, having at its upper or lower edges, or both of same, flanges which project outward from the band at an angle greater than a right angle.

When in use one or more of the bands or rings are placed side by side in the stuffingbox, the edges of the flanges being in contact with each other and in close relation to the wall of the box. The efficiency of the packing depends upon the fact that when the rings or bands are in position and pressed together the flanges will have a yielding force inward against the wall of the stuffing-box,aiid thereby act as wedges to force the body of the rings firmly against the rod to be packed.

The metallic rings or flanges may be used with entirely satisfactory results, either alone or in combination with vegetable or fibrous matter. If the latter is employed it will be for the purpose of packing the wall of the box and not the rod. The soft packing is removed fromcontact with the rod by the rings when used, and is thereby prevented from burning or being otherwise affected by heat caused by the movement of the rod.

The rings above described may be varied in form without altering the result accomplished. Several modifications are illustrated in the accompanying drawings, and referred to by letter hereinafter.

Figure l is a central vertical longitudinal section of a stuffing-box embodying the elements of the invention. Fig. 2 indicates a plan and sectional view of one of the packing-rings with soft packing applied between its flanges. Figs. 3, 4, 5, 6, 7, and 8 are views of modified forms of the packing, all of which are fully described hereinafter. Fig. 9 is an enlarged sectional view, showing in dotted lines the 50 flanges in a compressed state.

A indicates the wall of the packing-box, B the rod to be packed, and D the rings which constitute the packing. The rings D consist of a band,'m, having a flange or flanges, n, extending outward from the same at an angle greater than a right angle. The rings encircle the rod and are in contact with each other at a point beyond the band passing around the rod,'in order that when they are pressed together their flanges n will be forced against the walls of the box, and the bands m thus made to closely hug the rod B. It is desirable that the packing be made to fit the rod snugly, and be a trifle smaller than the interior of the packing-box, so as to permit the packing to be easily adjusted.

The packing-rings may be constructed in any convenient manner, either cast, turned, or rolled. In Fig. 3 is shown apacking in which the flanges have corrugated or serrated edges. I

In Fig. 4 the ring of the packing is in the form of a crescent, in Fig. 5 a half-cylinder, in Fig. 6 a section of hollow cylinder, and in Fig.

7 a plain ring havingtwo angular wedge-shaped flanges. All these forms embody the principle of the ring shown in Fig. 1, and are merely modifications of the same.

In Fig. 8 is illustrated a modification, which consists in giving the ring two flanges, b (1, one being at a right angle to the rod and the other, d, at an angle greater than a right angle. In this modification the yielding pressure is given by the flange d,which corresponds in all respects with the flanges n of the packing represented in Fig. 1.

When it is desired to use some vegetable or fibrous material in addition to the. rings l D-it will be placed around the ring and between the flanges n, as indicated at w in Fig. 2. As

hereinbefore recited, the vegetable or fibrous o packing will only be used to pack the wall of the box and not the rod.

In the manufacture of my packing I do not confine myself to any particular form of flange or band, the only essential consideration being 5 that when the packing is pressed up the edge of the flange will act as a wedge against the wall of the box to force the band closely around the rod.

I include within the scope of this application I00.

the employment of the rin gsD for all other packing purposes to which they may be applied,as well as for a steam-packing.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A packingring consisting of a band adapted to closely encirclethe rod to be packed, and having a flange or flanges which project outward from the same at an angle greater than a right angle and terminate at a point in near relation to the wall of the stuffing-box, substantially as specified.

2. A packing consisting of a ring or series
