Valve. No 240,754. Y Patented April' 26, I881."
UNITED STATES JEREMIAH OMEARA,
PATENT OFFICE.
OF NEl/V YORK, N. Y.
VALVE.
SPECIFICATION forming part of Letters Patent No. 240,754, dated April 26, 1881.
Application filed September 22, 1880. (No model.)
To all whom it may concern:
Be it known that I, JEREMIAH OMEARA, a citizen of the United States, residing at the city of New York, in the countyof New York and State of New York, have invented certain new and useful Improvements in Valves; and I 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,
reference being had to the accompanying drawin gs, and to letters or figures of reference marked thereon, which form a partof this specification.
This invention is in the nature of improvements in valves, cocks, or the like, for use on steam machinery, steam-pipes, and elsewhere.
The object of the invention is to prevent the detaching of parts bythe operating of the valve, and to improve the construction of the valve or disk holder, and the mode of securing its seat in place.
The invention consists, first, in a stop. or lock-nut or wash er applied to the bonnet, boss, or cap of a valve, to prevent the stuffing-box from being detached by the operating of the spindles, this part of my invention being specially applicable to the divided box shown in my Patent No. 213,239, dated March 11,1879.
The invention consists, secondly, in securing the valve or'disk holder in a threaded shouldered socket in the end of the spindle by a stem on such valve orholder havinglefthand screw-threads and a plain surface, whereby said valve or holder is screwedinto the stem or spindle; and its threads, passing the threads of the holder-stem, rest on the shoulder of the socket, and the valve or holder thenbecomes an accommodation-valvethat is, it is substantially swiveled to its spindle so as to accommodate itself to any inequalities or unevenness of seat, and such spindle having a right screw-thread, the valve cannot become accidentally or unintentionally detached.
The invention consists, thirdly, in a seatholder having a flan geless straight rim, a central teat, and an intervening space made with roughened or inclined walls, to hold and retain the seat or filling and permit the grinding off of the face to get a new face as the valve becomes leaky or is worn.
In the drawings illustrating my invention, in the several figures 0f which like parts are similarly designated, Figure 1 is a central vertical longitudinal section of a globe-valve embodying my improvements. Fig. 2 is a perspective view of a valve-bonnet with my stop, lock-nut, or washer, and one-half of my box in place, but partly broken away. Fig. 3 is a for insertion in said holder according. to my invent-ion.
It will be obvious that my invention is applicable to a variety of steam valves or cocks. I have shown it only in a globe-valve.
a is a valve bonnet, boss, or cap, having its upper end or neck screw-threaded, as at b, to
receive one-half of a divided stufifing-box, c,
said stuffing-box being adapted to contain the packing-disks, &c., d, and all operating as in my Patent No. 213,239, dated March 11,1879, hereinbefore mentioned. In order to prevent the turning of the valve-spindle from unscrew-I mg or running off the stufiing-box, I make an annular recess or shoulder, f, on the end of the bonnet-neck, and upon this shoulder I secure a washer or annulus, g, of external diameter about equal to the threaded portion of the bonnet at b or internal diameter of the box a. This washer is applied after the lower half of the divided box has been placed upon the threaded neck of the bonnet, and is retained by a screw-thread, as shown in Figs. 1 and 2, or by center punching, as at h h, Fig. 5, and when thus attached to the bonnet,its external diameter being equalto the internal diameter of the box, the threads of such box cannot pass it, and it hence acts as a stop or lock-nut to prevent the removal or accidental detachment of the box, such detachment being a source of much annoyance and often damage in the ordinary form of valves. This part of my invention is applicable in all kinds of machinery in which my said stuffing-box may be employed.
too
In the end of the valve stem or spindle i, 1 form a socket, shouldered or counterbored at j, having an upper contracted portion, 70, and a screw-threaded orifice, l. The valve or disk holder m, I make with a stem, 11., on its head, which is provided with a left-hand thread, 0, to engage in the threaded orifice Z of the spindle 'i, and also has an extension, 19, to enter the contracted portion 70 of the socket in the spindle. When the left thread 0 has passed above the threaded orifice Z inwardly, as in Fig. 1, the stem 19 has entered the portion 7a, whereby the holder m is stayed in the spindle, and the left thread 0 resting above the threaded orifice and in the shouldered or counterbored portion j, the holder or valve becomes practically swiveled to the spindle, and is free to' turn with the spindle beyond a peradventure of becoming detached, it being noticed also, to this end, that the spindle-screw q is right hand and the valve or holder screw left hand. The valve or disk holder thus becomes, also, what is known to the trade as an accommodationvalve, because of its self-adaptation to any unevenness of seat. I do not limit this part of my invention to any particular form of valve or holder.
The metal holder hereinbefore designated by the letter m is made with a straight or flangeless annular rim, 4, the inner face of which may be grooved, ribbed, roughen ed, or beveled, and I provide a core or tea-t, s, which may be similarly surfaced, as shown. A space, t, will be left between the teat and rim, and into this space I press arubber-com position disk or ring, a, which is afterward hardened in said space by heat and pressure, and thereby firmly secured therein. This inserting and hardening of the ring or disk in its holder may be effected by means of an ordinary vulcanizing-press. When the ring or disk is hardened the holder with its contained disk is removed from the press and its face ground smooth. As such face is damaged or worn the holder may be readily removed and sandpapered or ground smooth and even upon an emery-wheel or other abrading means employed for effecting the same object, and this resurfacing may be repeated until the holder and its disk are con-. sumed.
It will be seen that the rubber disk is practically immovablyfixed in the holder,although, if a faulty disk had been inserted, it may be dug out and replaced by a new one.
The valve-bearing o and the valve will be so proportioned as that little or none of the filling u will be exposed to the direct action of the steam or other fluid.
What I claim is 1. The combination, with a divided stuffingbox and the part to which it is applied, of a washer, stop, or lock-nut interposed between them and adapted to operate toprevent the detachment of such stuffing-box by the working of the machinery, substantially as described.
2. In a valve, the combination of a threaded bonnet or boss, a divided stuffing-box applied to such bonnet, and a washer or annulus arranged upon said threaded bonnet above the lower portion of such box, to prevent the detachment ol'such stuffing-box, substantially as described.
3.""In a valve or cook, a threaded spindle having a screw-threaded and shouldered or counter-bored socket in its lower end, in combination with a valve or valve-holder provided with a left-hand screw-threaded stem to enter and swivel in said socketed spindle, to form an accommodation-valve and prevent the accidental detachment of such valve or holder, substantially as described.
4. In a valve, a valve-holder formed with a straight or fiangeless peripheral rim and a central teat, the opposite faces ofwhich are roughened, ribbed, or beveled, in combination with a filling or disk inserted and hardened between and held by said rim and teat, whereby said valve-holder and filling may be ground or sandpapercd when worn or leaky, to form a new steam, water, and gas tightface, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
JEREMIAH OMEARA.
