IMPROVEMENT lN STOP-SOCKS.
Specification forming part of Letters Patent N o. [94.321, dated August 21, 1877; application led May 19, 1877.
To all whom t may concer/n.:
Be it known that I, GEORGE C. BAILEY, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Stop-Cocks; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, in Whichlike letters indicating like parts- Figure 1 is a sectional elevation of my improved bib or stop cock.
My present invention relates to an improvement in the class of cocks referred to in Letters Patentgranted to me June 4, 1872, No. 127,547, by means ot' which a swiveled cap, having a Waste port or tube, is adjustably combined with the valve and case, so that the direction of the discharge of the Waste may be varied or regulated at pleasure.
Such cocks, in practical use, have to be arranged in various positions, sometimes horizontal, sometimes vertical, and sometimes oblique; and hence, in the absence of means of adjusting and regulating` the position of its waste-port, such port not unfrequeutly discharges in a direction or in a place where the presence of water is highly objectionable.
ln the drawing, A represents the supplypipe, and B the discharge-pipe. The usual valve-seat imade in the diaphragm B', and
' theY valve a, of suitable form, with suitable packing, is guided in its motion by wings a.
The stem b of the valve is threaded, as shown, and works in a tapped socket, d, of the operating-stem D.
The swiveled cap is represented at c. It is iianged at its lower end, as shown at c', and an ordinary threaded flange-union, g, connects it with the valve-case.
A packi11g-ring,s',is interposed between the ange c and the valve-case, and this packingring is further supported, if need be, by a nietallic washer, s, the threaded valve-stem b playing loosely through both.
The lower end of the operating stem D is flanged, as at d', and between 'such ange and the top of the cap I arrange a spiral spring,
le, which is so adjusted ae to its elastic force as, when free so to act, to force the lower end of the operating-stem into close contact with the packing-ring s.
The stem D is itself properly packed, Where it passes through the cap c, by suitable packing, as at e.
At any desired point in the periphery of the cap u, I make a Waste-port, a, either with or without a short waste-tube, n.
The first effect of turning the stem D in the proper direction for opening the valve is ,to relieve the compression on the spring e, so that the lower end of socket-stem shall be seated on the packing-ring s. The Waste is thus cut off. The turning motion being continued, the valve is opened.
In closing the valve the reverse action takes place. The valve is first seated, then the socket-stein is raised, and the Waste is open to the discharge-pipe. The Water in the discharge-pipe will then escape at the Wasteport n.
Now, in putting up the cock, before the iiange-union gis tightened down, the swiveled cap c is to be turned to such position that its waste-port n will discharge the Waste water in a direction or in a place Where its presence is least objectionable. This being done, the union g is screwed down, so as to lock or secure the cap in that position of adjustment. The jet of Waste water will not then interfere with the convenient use ofthe cock under any ordinary circumstances.
A swiveled cap having a waste-port may be combined with valves and valve-cases of other constructions, and having other means of opening and closing the waste, Without any `substantial departure from the scope of my invention, and such modifications are hereby included herein.
I claim herein as my inventionl. In a stop or bib cock, the combination of a swiveled -cap having a waste-port therein, with a valve and valve-case, substantially as set forth.
2. The combination of swiveled cap c, having waste-port n, socketed and flanged operating-stem D, valve a, having threaded. stem b, packing-ring s', and flange-union g, with a valve-case, substantially` as set forth.
ln testimony whereof I have'hereunto set my hand.
