CORNELIUS OALLAHAN, OF CHELSEA, MASSACHUSETTS.
CUT-OFF FOR VALVES.
SPECIFICATION forming part of Letters Patent No. 299,734, dated June 3, 1884. Application filed October a, 1883. (N model.)
To all whom it may concern.-
Be it known that I, CORNELIUS GALLAHAN, of Chelsea, county of Suffolk, State of Massachusetts, have invented an Improvement in Gut-Offs for Valves, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
My invention relates to a cut-off for water and other pipes; and it consists, primarily, of a shell or case having a valve composed of two disks connected by a thin web, which is packed at its working edges.
/ My invention consists, secondly, of a shell I 5 or case having preferably a stepped seat, and a valve composed of two disks held together by a thin web packed at its edges, combined with a packingannulus and a threaded ring or plate adapted to hold the valve in place.
The object of my invention is to provide a strong, compact, tight fitting, valve, which, when open, offers the minimum of obstruction to the flow of water through the shell or case.
Figure l is a longitudinal vertical section of my improved valve, showing all the parts. Fig. 2 is a horizontal section thereof, to clearly illustrate the packed meeting edges of the thin web of the valve. Fig. 3 represents the valve removed from the shell or case in which it is to rotate.
A A mark two'disks, held together by athin web, A and'having a shank, a, projecting from the upper disk, A, the whole forming a valve, which is stepped, as at b, in the closed bottom or seat B of the shell or case B. The
seat B is recessed for the reception of a packing-annulus, 0, upon which rests the lower disk, A, of the valve, the purpose being to provide a tight fit at that point where the 0 valveis properly secured in place. Theworking edges of the thin web A which hug-the walls of the shell or case B, are grooved, and the grooves are filled with packing M, to prevent any possible escape of fluid when the valve is closed. Apacking-annulus, D, rests upon the upper disk, A, of the valve, which latter is firmly held in place and a tight fit made at the edges of the upper disk by means of the annular nut E, which is screwed into the open side of the shell or case, as shown, thereby pressing the packing-annulus D against the upper disk, A, and forcing the lower disk, A, against the packingannulus O, as will be clearly understood by referring'to Fig. 1. The shank a of the valve projects through a central opening in the cap F and receives a handle, a, of the usual construction. The cap, as herein shown, is interiorly screw-threaded, and engages with the nut E.
The escape of fluid when the valve is closed is provided against not only by means of the packed working edges of the web A and the packing-rings O D, but also for the reason that the disks A A are arranged in recesses in the sh ell or case, respectively above and below the line of flowof thefiuidin the pipes joinedwith the said shell, and the peripheries of the said disks meet the walls of said shell or case to further guard against the escape of fluid.
I claim-- 1. The cut-off composed of a case or shell and disks A A, held together by a thin web, A', having its edges provided with packing, substantially as described.
2. The combination, with the case or shell, which is closed at its bottom and provided with the packing-annulus O, of the valve composed of the disks A A, and web A, having the packed working edges cf, the said valve being stepped in the bottom of the shell or case, as described, and with the packing-annulus D and retaining-nut E, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two 85 subscribing witnesses.
CORNELIUS GALLAHAN.
