MASSACHUSETTS, ASSIGNOR TO THE STOP AND WASTE COCK- SPECIFICATION forming part of Letters Patent No. 795,005, dated. July 18, 1905. Application filed March 2'7, 1905. Serial No. 252,117.

To all whom it may concern:

Be it known that I, GEORGE M. PAGE, a citizen of the United States of America, residing at Haydenville, in the county of Hampshire and Commonwealth of Massachusetts, have invented a new and useful Stop and Waste Cock, of which the following is a specification.

My invention relates to what are known as right and left hand stop and waste cocks that is to say, cocks which may be set to opcrate either to the right or left, as desired, for the purpose of shutting off the supply and opening the waste; and it consists of a body provided with a notched head, a plug having a flange, and a cap with an interior lug, all combined and arranged in the manner substantially as and for the purpose herein set forth; and the object of my invention is to provide simple, compact, strong, durable, and sure means for controlling the flow of Water and for quickly, easily, and conveniently changing or rearranging the parts to reverse the direction in which the plug must be turned in order to properly operate the valve. 1 attain this object by the means illustrated in the accompanying drawings, in Wl1lCl1- Figure 1 is a front view of the device; Fig. 2, a vertical section through the same; Fig. 3, a side view of the key shown in Fig. 1; Fig. 4, an inside or bottom view of the cap, and Fig. 5 a top view of the body and plug without the cap and key.

Similar letters refer to similar parts throughout the several views.

Although I have shown my invention as ap-. plied to a stop and waste cock, it is to be understood that it is equally applicable to valves which are not provided with waste-passages.

The valve casing or body a is of the usual construction, having through-passages b b, the drain-opening c, and a chamber for the tapered valve-plug d. The head a, of the body a has a chamber a therein, the walls of which are notched at c and e. The plug (Z is held in place by the washer f and the nut g in the usual manner. A flange h partially surrounds that portion of the plug (Z which is within the chamber a and affords stop-shoulders 1? and a".

An angular recess d is formed in the top of the plug to receive the corresponding part of the key 3'. The through-passages b in the body may communicate with each other through the port is in the plug d, and said port may communicate with the waste-opening c in said body and with either of said throughpassages, owing to the presence of the wasteport Z in said plug.

In addition to the parts above described I provide a cap m, having a central opening at and adapted to fit over the head a of the body, the top of the plug (Z passing through said opening. Inside of the cap m is a lug n of the proper size to be received into either the notch e or the notch c and to project into the chamber a into the path of the flange h on the plug d.

The direction in which it is necessary to turn the plug (5 in order to close the valve is determined by the position of the lug a, or rather by the notch c or e in which said lug may at the time be located. When the cap at is arranged With its lug in the notch c, the stop-shoulder bears against the adjacent side of said lug at the time the valve is open, so that further movement of the valve to the left is prevented; but said valve can be turned to the right until the stop-shoulder z" encounters the adjacent side of the lug, when further movement must cease and the valve is closed and the waste opened, this assuming that the supply enters the body at the end indicated by the arrow in Fig. 2. In the event that the supply enters the body through the end opposite that indicated by the aforesaid arrow in order to shut off the supply and open the waste it becomes necessary to rearrange the cap 171 so that the lug a instead of being in the notch c is in the notch 6'. Now in order to close the valve it is necessary to turn the plug to the left until the stopshoulder 71 encounters the lug n, the reverse movement which brings the stop-shoulder into engagement with said lug opening the valve again. Thus it will be seen that the cap on, in connection with the notched walls of the chamber 0/, serves the double purpose of limiting the movement of the plug and of affording means for changing the direction which is to be given the plug in closing. Furthermore, this cap protects the valve from dirt and dust which might otherwise get into the same and cause more or less wear so as to interfere with its proper working.

In the upper part of the plug (Z above the cap on a screw-thread ed hole 0 is provided, as'indicated by dotted lines in Fig. 5, into which a screw 1) is inserted to bear against a chamfcred part j of the key 7' and retain said key in place in the recess (25'. The head of the screw 11 comes over the top of the cap m and holds said cap in position, so that its lug cannot Work out of the notch with which the same is engaged. To change the lug n from one notch to the other, it is necessary, of course, to remove the screw p and then replace it after the change has been made. Any other suitable key or operating implement may be substituted for the key j.

As before intimated, in order to close the valve illustrated in the drawings it is necessary to turn the plug to the right from the position shown,wherein the valve is open, and 150 open the same again the movement is to the eft.

W'hatI claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a valve, of a body having notches in the head thereof, a plug seated in said body and provided with stopshoulders, and a cap having a lug adapted to enter either of said notches and to extend into the path of said stop-shoulders.

2. The combination, in a valve, with a body provided with a chamber in the top with notches in the walls of said chamber, and a plug seated in said body and provided with stop shoulders adapted to operate in said chamber, of a cap provided with a lug adapted to enter either of said notches and to lie within the path of said stop-shoulders.

3. The combination, in a valve, of a body having notches in the head thereof, a plug seated in said body and provided with stopshoulders, a cap having a lug adapted to enter either of said notches and to extend into the path of said stop-shoulders, and means to retain said cap in place.

4. The combination, in a valve, of a body having notches in the head thereof, a plug seated in said body and provided with stopshoulders, a cap having a lug adapted to enter either of said notches and to extend into the path of said stop-shoulders, means for op erating said plug, and means to retain such operating means and said cap in place.

5. The combination, in a valve, of a body chambered at the top with notches in the walls of the chamber, a plug seated in said body and provided with a flange having stop-shoulders at its ends, and a cap provided with a lug adapted to enter either of said notches and to extend into said chamber into the path of said stop-shoulders, which latter and the flange are also situated in the chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE M. PAGE.
