sPEcIFIcATIoN forming part of Letters Patent No. 512,892, daten January ie, 1894. Application iiled March '7, 1893( lSerial No. 465,041. (No model.)
To a/ZZ whom it may concern:
Be it known that I, GEORGE MUNGER, of East River, in the county of New Haven and State of Connecticut, have invented a new Improvement in Stop-Cocks; and I do hereby declare the following, when 'taken inv connec-` tion with accompanying drawings and the let# ters of reference marked thereon, to be a full; clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure l, a view in side elevation of a stopcock constructed in accordance with my invention; Fig. 2, a view thereof in vertical longitudinal section; Fig. 3, a view in trans-v verse section on the line :ic-x of Fig. 2 5 Fig.' 4, a detached View in side elevation of the valve with its cover removed and its stem partly broken away; Fig. 5, a similar view of the valve-cover; Fig. 6, an end view of the valve with its cover in place; Fig. 7, a 'detached view in side .elevation of the lining employed for the valve-chamber; Fig. S, a de-l tached view of the sleeve or collar which sur# rounds the valve-stem.
My invention relates toan vimprovement in straight-way stop-cocks, the object being to produce a simple, durable, and effective device, adapted to have its wearing surfaces renewed when worn, and constructed to have the pressure within the supply-pipe leading to it, constantly maintainedl'on the valve, whereby the same is always firmly held on its seat.
With these ends in viewtmyinvention consists in a straight-way stop-cock having certain details of construction and combinations vof parts as will be hereinafter described and pointed out in the claims.
The shell or body A, of my improved device is constructed with a tapering or conical valve-chamber A', which extends entirely through it, and with internallythreaded facedl hubs A2 A2, located ata right angle to the said chamber on opposite sides thereof, and adapted to respectively receive the inlet and outlet pipes which lead to and from the device, the said pipes not being shown herein.
Ports ct a lead from the bottom of the said hubs into the said valve-chamber, which they intersect at opposite points at a right angle. TheV said chamber is provided with a conical :lining B, (Fig. 7,) adapted to fit into it closely, and to project slightly beyond its larger end,
as shown in Fig. 2, and having two openings B B', formed at opposite points in it,
to register with the ports a a before mentioned. This lining is struck up from sheetmetal, and not vonly reduces the expense of constructih'g'th'e stop-cock, but also makes lit more durable for the reason that sheetmetal is much harder than the cast-metal employed for the body or shell of stop-cocks.
Moreover, the said lining, by its capacity of being renewed, prolongs the life of the cock. It has already been mentioned thatothe larger end of the liningB, projects a little out of the said chamber, as shown in Fig. 2 of the drawings. This'is to provide forwitswengagementib'y the screw-cap C',"'whi"c"h takes into an exteriorly` threaded.. neck or hub C', f ormed integral withfthe body A, concentric with the outer end of the valve-chamber A thereof. This cap, which, is furnished with afaced head C2, like a bolt-head, by itsengagement with the said end of the'liningfforces the same inward, and holds it firmly in place. rPhe conical valve 1), which has a straight stem D',A conforms to the shape of the said valve-'chamber A', but is made shorter than the same so as to forma pressure-chamber D2,between its largerend and the inner thee of the cap C. The said valve is constructed wlth a straight transverse passage d, correspondingvin shape to the ports a a inthe body A, and to the openings B B in the linlng B, and is arranged to align witlnthe same to form a straight passage through the stopcock,when the valve is turned intorightposition. The formation of such a straight passage through the stop-cock, characterizes it as a straightway stop-cock. The outer wall of the primary passage d, is interscctedby the inner end of a longitudinal passage d', formed 1n the valv and opening at its outer end into the pressure-chamber D2 efore mentioned. The valve isfalso constructedwith a small secondary passage cl2 located, in the same `transverse plane with the primary passge d,
passage d in line with the ports a. and o. of
ICO
2 masse the body A, the passage cl2 will be closed by its presentation to the lining A of the Valve- Chaflbel, but when the valve is in its closed POSlQlOn, the passage d2 will be in line with the inlet port a, and admit water or Steam into the pressure-chamber D2, whereby the pressure under which the stop-cock is operated will be exerted againstthe large end of the v alve, which will thus be automatically held in place and kept tight. By this simple construction, I provide, in a straight-way stop cock, for constantly maintaining the pressure within the supply-pipe upon the valve, when the valve is closed. The valve I provide with a conical sheet-metal cover E, constructed with two openings e e arranged to align with the respective ends of the passage CZ of the valve and with an opening e', corresponding to the passage cl2 therein. The said valve-cover is secured in place at its larger end by two ears e2 e2, formed integral with the same, and adapted to be turned down 1nto recesses da cl3 formed in the larger end of the valve, as shown in Figs. 2 and 6 of the drawings. The smaller end of the cover is closed by a flat wall located in a plane at a right angle to its longitudinal axis and constructed with a square opening (Fig. 5) conformlng 1n size to the size in cross-section of the square stem D of the valve, the cover belng therefore held against rotation at its smaller end by the passage of the valve-stem through its said opening. The iiatend wall of the said cover bears against the flat shoulder formed at the base of the valvestem as shown in Fig. 2 of the drawings. Of course the opening formed in the smaller end of the cover need not be square, nor is it necessary to make the valve-stem square in cross-section, my invention comprehending, so far as ythis point is concerned, any construction whereby the cover will be locked against rotation on the valve, by means of the valvestem. The smaller ends of the lining B, and the cover E extend just to the end of the smaller end of the valve-chamber A', as shown 1n Fig. 2 of the drawings, and are abutted against the inner end of a sleeve F, encircling the valve-stem D', and seated at its said inner end directly against the body or shell A of the valve. The outer end of the said valvestem receives the turn-key or handle G, which bears against the outer end of the sleeve F and is held against the same by a screw I'I which enters a threaded socket 7L, formedV in the end of the stem, whereby additional provision is made for keeping the valve tight, and taking up wear, for it is apparent that by means of the screw H, the valve maybe drawn inward, at which time the head of the screw I-I, bears against the outer face of the turnkey, the inner face whereof bears at the saine time against the outer end of the sleeve F, which in turn bears at its inner end directly against the shell or body A of the cock.
I have already pointed out that by means of my improved construction, I secure the advantages of a straight-way stop-cock, with the additional advantage of having the pressure within the su pply-pi pe constantly maintained upon the valve for holding the same firmly on its seat.
lBy employing the sheet-metal lining B, for the valve-chamber, I reduce the expense of the device, for the lining avoids the necessity of finishing the valve-chamber, for which reason I may employ in the construction of` the body of the valve, cast-iron, which is too hard to be finished, or I might make the body of brass, and still effect an economy by using the same without linishing the valve-chamber. lVhen the lining becomes Worn, it may be replaced, and the valve made as good as new. The same is true of the cover of the Valve, by means of which I avoid the necessity of 1inishing the surface of the valve. Then worn the cover may be replaced. Both the lining and the cover being made of sheet-metal, are smooth enough, and do not require extra finishing. By means therefore of the lining and cover, I not only avoid much expensive fitting of parts, but also I am enabled to employ cheaper metal in the construction of the device, and to prolong the life of the same by the renewal of parts when the device becomes worn in use. I do not, however, limit myself t-o the use of the lining or cover, for one or both of them may be dispensed with,in which case the advantages of my construction as a straight-way stop-cock adapted for the constant maintenance of pressure upon the outer end of the valve would still remain, but as aforesaid, I prefer to avail myself of the ad vantages derived from these removable wearing surfaces.
If desired I may close one of the internally threaded faced hubs A2 of the body A of my device, and adapt the same to have a supply- `pipe connected with it in line with the larger end of its valve-chamber. In that case I might either dispense with the cap C, or the same might be constructed to form a tting for such a supply-pipe. I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
I am aware that it is old to construct a straight-way stop-cock so that pressure will constantly be maintained upon the valve for holding the same firmly upon its seat.
I ain also aware that it is old to furnish a valve-seat with a removablelining and to pro vide a valve with a cover or wearing surface. I do not therefore claim either of those constructions broadly.
IIaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a stop-cock, the combination with a conical valve having its larger end constructed with two recesses, of a conical sheet-1netal cover therefor, constructed at one end with IOO , each other, of a removable, conical sheetpassage arranged to align with the said inlet metal lining located in the said chamber, and projecting beyond the larger end thereof, a screw-cap closing the outer end of the said chamber and abutting against the larger end of the said lining which it holds in place, a
conical valve located-in the said chamber, but made shorter than the same to form a pressure-chamber between its larger end and the said cap, and constructed with a transverse and outlet ports when the valve is turned into right position, and also constructed with a longitudinal passage leading from the outer wall of its transverse passage to its outer end,
and with a small passage leading into the said longitudinal passage and located in the saine transverse plane as its transverse passage; a removable conical sheet-metal cover applied to the valve so as not to rotate thereupon, the said lining and cover being constructed with openings corresponding to the ports and passages of the body of the cockr and the valve; a handle applied to the outer end of the valve-stein, and a sleeve interposed between the handle andthe said body, and having the smaller end of the lining and cover located adjacent to its inner end which rests primarily upon the body, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscrib-y ing witnesses. f
