PACKING FOR VALVESTEMS.
SPECIFICATION forming part of Letters Patent No. 611,386, dated September 27, 1898. Application filed December 3| 1897. Serial No. 660,664. (No model.) l
To all whom t may concern:
Beit known that I, JAMES H. MAURER, a citizen of the United States, residing at Hamburg, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Packing for Valve-Stems; andI 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.
My invention relates to packing for valvestems, is designed to dispense with the stuffing-boxes and glands generally used to prevent leaking of fluids or liquids, and consists in certain improvements -in construction, which will be fully disclosed in the following specification and claims,
In the accompanying drawings, which form part of this specification, Figure 1 represents a side elevation of a valve-case; Fig. 2, a vertical section ofthe same; Fig. 3, a transverse section of the valve-stem and packing on line 3 3, Fig. 2; Fig. 4, a like view on line 4 4; Fig. 5, a vertical section, partly in elevation; Fig. 6, a transverse section of the valve-stem Fig. 7', a vertical section of a modified construction of the valve-stem, and Fig. 8 aplan view of the lower end of the same. Reference being had to the drawings and the letters thereon, A indicates a valve-case, B the valve, and C the hand1e,which is secured to the valve-stem in the usual manner, and all of which may be of any approved form, as they constitute no part of myinvention. The valve shown is of the type known to the trade as radiator-valves and is of the turningplug variety. The valve-stem is cylindrical at a. and, non-cylindrical at b and at its lower end is bent at c at a right angle to the body of the stem, and the part c engages a slot d end of the valve B, as shown in Figs. 2 and 5, to turn the valve inthe valvecase to regulate the now of liquid or fluid.
D indicates the packing, which is made of rubber and may be molded on the valve-stem and secured to the non-cylindrical portion b, but is free to turn on the part a, and at the lower end of the cylindrical portion h of the packing which surrounds the'valve-stem is a flange e, which rests upon the upper end f of the valvefcase and packs the joint between the valve-case and the cap g, while the escape of liquid or fluid around the valve-stem is prevented by its surrounding packing h.
The packing surrounding the valve-stem is inclosed by a casing E, extending fromthe cap g to the under side of the handle C, and the flange e is protected against excessive heat by a disk i, of asbestos or other non-conductor of heat, applied to the inner surface of the liange e and. also secured in position by the cap g of the valve-case.
The upper portion of the packing surroundl ing the valve-stem is prevented from turning thereon by the non-cylindrical part b of the stem, while the lower portion is free, and in l turning the valve this portion of the packing is twisted, as indicated at lain Fig. 5, while the flange e and the upper portion of the packing remain stationary.
It is obvious that other irregular forms may be substituted for the flat portion b of the valve stem or that the stem may be cylindrical throughout its length, as shown at Z in Fig. 7, a head m above it, to the lower end of which head and to the upper part of the cylindrical portion l adjacent to the head the tubular portion k of the packing is secured by sweating or lby any other means to cause the packing to turn with the stem at its upper end, while the remaining portion is free to twist in turning the valve-stein, thereby permitting the packing to be moldedupon a metallic core otherA than the valve-stem in the usual way of molding rubber articles andl put on the market as an article of manufacture to be supplied to the trade.
On the lower end of this valve stem is a plate n, having projections o o, Fig. 8, to engage the valve in place of the bent part c of the valve-stem.
Having thus fully described my invention,
' what I claim is 1. A` valve-stem provided with a flexible packing surrounding the stem, part of which is secured to the stem and part free and a flange at its inner end to engage the valvecase. y
2. A Valve-stem provided with a iiexible ICO packing surrounding the stem, secured to a part thereof, extending outside the body of the valve and having a flange at its inner end to engage the valve-case.
3. A valve-stem provided with a iiexible packing, part being secured to the stem and having a flange at its inner end to engage the valve-case', and a heat-protector on the inner surface of the flange.
4. A valve-stem having a portion thereof cylindrical and a portion non-cylindrical, in combination with a iiexible packing surrounding said stem and provided with a iiange at its inner end to engage the valve-case.
5. A. valve-stem having. a portion thereof cylindrical anda portion non-cylindrical, in'
combination with a iiexible packing secured to the non-cylindrical portion and free on the cylindrical portion and having a ange at its inner end to engage the valve-case.
6. A valve-stem provided with a packing surrounding the stein, secured to a part thereof and having a ange at its inner end to engage the valve-case and the stem extending through the flange and constructed to engage with a valve.
7. A valve-stem provided With flat and cylindrical portions, and a right-angled extension at one end, in combination with a packing surrounding the stem and having a flange at its inner end to engage the valve-case.
8. A valve-stem. provided with a packing surrounding the stem, part being secured thereto and having a flange at its inner end to engage the valve-case and a supplemental casing extending from the body of the valve and inclosing said packing.
9. An article of manufacture, a packing for valve-stems consisting of an elongated cylindrical portion to surround the stem and a Iiange at its inner end to pack the joint be tween the valve-casing and its cap.
In testimony whereof I affix my signature in presence of two witnesses.
