WILLIAM S. COOPER, OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent N0. 75,376, dated March I0, 1868.
IMPROVEMENT IN VALVE-noose,
TO WHOM IT MAY CONCERN:
Be it known that I, WILLIAM S. COOPER, of Philudelphin, Pennsylvnn'ia,,huve invented an Improvement in Valve-Cocks for Steam or W'ater; end I do hereby declare the following to be a full, clear, and exact description of the some, refercnce'being had to the accompanying drawings, forming a part of these specifications, and to the letters of reference marked thereon.
'My invention relates to improvements in that class of valve-cocks in which a valve operated by a. screw-l spindle is used for controlling the flow of-woter or steam through the valve-cock and my improvement consists in the manner in which the valve is guided to its seat, to close the passuge-wam aud which being done, to waste, if desired, the returning water or steam from the body of the cock and pipe also in the manner in which]: form a. water' tight snd durable jointbetween the spindle and the cop through which it passes. I
I In order to ennble'others skilled in the art to which this invention whites to ake and use my'invcntion, I will now proceed to describe its construction and operation.
In referring to the accompanying drawings, in which similar letters refer'to similar parts throughout the several partsl Figure lis n. sectionnllelevction of the valve-cock, showing the arrangement of its internal parts. I
Figure 2 is an elevation of the cap,wnste-tube, and part of the screw-spindle, with the valve drawn up to its full height, and-representing its upper face he closed against its seat, so the cool: cannot waste.
Figure 3 is an elevation of the valve, part being in section, to show the arrangement oi the elastic valve faces, and one way they may be held in plcco.
Figure 4 is a plan of the valve, showing at a; the square shank of the some.
Figure 5 is an under view of the cap, showing the square socket which receives the square shank z of the valve, toprevent the rotation of the latter. b
-As regards the-external shape of the valve-cock, it may be as represented, when it is suitcble for the purpose of a stop and waste, or a. different Iorm may be used 'to fit'it for a different purpose.
Construction.
Referring to fig. 1', it is shown that B is the body of the cock, with its inlet I, and outlet 0, and having screwed into it the cap C, the joint between them heingvmnde tight by the metallic packing Z, which fits into a recess in the cap 0 made to receive it. The cap 0 is constructed'with n. screwed chamber in. its upper part, outside of the body B, and through the bottom of this chamber is o small hole, and below this hole, and in the part of the cap which is inside the body B, is another chamber-,M, the lower part of which is made with a square socket, as shown in fig. 5, to receive the square shank x of-t he valve N, the object of this being to prevent the rotation of said valve. On the lower face of the said cap is a raised seat, W. The spindle is made onthe top to receive a. suitable handle, and is threaded at its lower end to fit the screw inside the square shank-210i thevalve N.v Above this screw S is u collar, a, on-either side of which are placed .suitublo packings, p and 12'; us shown,which collar and pnckings fit neatly into the upper screwed chamber oftho' cap C, nnd arc pressed to its bottom, and compressed by means ofthe packing-nut D suiiiciently to make the jpint water-tight. .A hollow bent tube, 1, is fixed in some suitable manner in a. passage, t, in the cap C, communicating with its chamber M, as shown in fig. 1. The valve Nis constructed withits'two faces Vnnd W. Its lower face has a flnngcdrecess,
' n, into which is forced the elastic rubber face V; this recess, with its finnge n, protecting the-edges of the rubber from being frayed or rolled over. The rubber-valve face is held in position by the saidrecessed flange n, and the-screw cl or its equivalent. On the upper side of the valve is another recess, with a. flange formed at itsinner edge the outside edge being plain and straight, and into this recess is forced the elastic packing'W'r Its square shank x, as seen in fig. 4, fits into the square socket of the cap G, and is threaded on the inside to receive the screw S of the spindle H.
Operation.
Whcn it is desired that water or steam shall pass to pipes or reservoirs connected with the outlet 0, the spindle II is rotated, and, by means of its screw, thevvslve N, with its elastic face V, is raised from its sent V", and until its fnce'W' is pressed to its sect at the bottom of the cap (3, as shown infig. 2, thus giving ngfull 't, substantially as specified, nnd'for the purpose described.
passage for water or steam through the body of the cock, and shutting of! all communication with the chamber M of the cap 0, and thus with the waste-tube t or passage t.
It is evident that when the valve-face V is returned to its seat V, theupper valve-face W-will be withdrawn from its seat W, as shown in fig. 1, and a. free passage will exist between the shank :v of the valve'lLond the squaresoeketof'the cap G into the chamber M, so that any water or steam contained in pipes or reservoirs connected with the outlet 0 may flow freely through said passage to the-said chamber M of the cap 0, and escape thence through the waste-tube t. I
I do not propose to confine myself to the method of holding the elastic valve-packing Vin place, :is indicated I in fig. 1, but may employ a flanged sleeve, in, screwing on the'periphery of the valve N, as indicated in fig. 3.
Nor do I propose to confine myself to the use of the soft-rubber valve-face V, but may employ, when thought...
desirable, a metallic valve, as when steam ofa high pressure is to be passed.
I am well aware that valve-cocks have been made in which various valve-puckings have been-used, withpr without a packing-nut; and I also know that waste-tubes have been attached to stop-cooks, to conduct the fluid away from above the cock; and, moreover, I know that vnlve-cocks have been made in which a raised seat is used in connection with a soft valve-face, butI know of no other arrangement like the one here described and represented. v i
' I therefore claim as my invention, and desiretosecure by Letters Potent v The combination of the valve 71, spindle H, with its screw S; the cap 0 with its chamber M and waste-passage WM. -S. COOPER.
