WASTE AND STOP COCK.

SPECIFICATION forming part of Letters Patent N o. 479,544, dated July 26, 1892. Application filed August 29, 1891. Serial Nin/104,054. (No model.)

.T0 @ZZ whom, t may concern:

Be it known that we, GEORGE H. BAILEY and THOMAS GRACE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in IVaste and Stop Cocks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figures 1 and 2 are front and rear eleva` tions, respectively, of our improved Waste and stop cock, and Fig. 3 is a vertical section thereof on the line III III of Fig. l.

The object of our invention is to provide a waste and stop cock for plumbers use, adapted to be used either as a right-hand or as a left-hand cock, and to be employed with various kinds of operating-handles, with T-handles or with an L-shaped handle extendingin one direction only, orwith a handle consisting of a long` rod, which may extend from the cock to a distant point. Vith stop and Waste cocks as commonly employed, in which the motion of the stem or plug is limited by a fixed pin or projection Working in a slot or groove in the exterior shell of the cock, the device can only be employed so that its handle shall be on one side. The right-hand cock cannot be turned and used as a left-hand cock, and consequently in fitting a building the plumber must carry cocks of two distinct sorts. We overcome this inconvenience by constructing our improved cocks so that they are interchangeable and that each may be used either as a right-hand cock or as a letthand cock, ascircumstances may require.

Other advantages of our invention in respect of convenience and simplicity of construction, efiicieucy, and durability will appear to those skilled in the art.

As shown in the accompanying drawings, the shell of the cock is of general form, having at the opposite ends tubular portions 2 3, to which the water-pipes are connected, so as to conduct water through the shell. The rotary plug or stern 4 extends at right angles to the line of the portions 2 3 within a cylindrical part 5 of the shell, and has extending through it transversely the usual slot or waterv shell.

passage 6 and at rightangles thereto a smaller hole or passage 7. The cock operates in the usual way. When the stern is turned so that the slot (i shall register with the tubular portions 2 3, it affords an unobstructed passage for the water through the pipes. It, however,

the stern be turned through an angle of nine-Y ty degrees, it brings the hole into register with the tubular portion 2 and the slot G into register with a hole 8, made in the front of the cock-shell, substantially at right angles to the line ot the Water connections 2 3, so that the Water is prevented from rising in the water-pipe, while the Water in the pipe above the cock escapes through the hole 8. In 0rder to limit the rotation of thevalve stem or plug to the arc of ninety degrees above mentioned, we provide the valve-shell with stops 9 and l0, formed, preferably, by cutting out or mitering the end of the shell, as shown.

VIn conjunction with these stops we use a washer 1l, which fits on the end of the stem, and has at its margin an inwardly-projecting tongue l 2, adapted to Work between said stops. The washer and the end of the plug or stem are provided with holes adapted to register and to form a socket for the reception of the handle or lever 13, which may be either an VL-shaped handle or may be of ordinary T shape, or may consist of a long rod extending from the cock to a distant point. Instead of using this socket, the end of the stem may be squared for the same purpose. The mitered or recessed portion formed in the cock-shell to constitute the stops is situate symmetrically either on the front or back side of the This is essential, in order that the cock may be reversed, so as to act either as a right or left hand cook, and is important, also, because in casting the shell the mitered portion, being altogether on one side, can readily be formed in molding. It will be understood, however, that instead of forming the stops by mitering the shell, they may be constituted by special pins or projections iiXed to or formed integrally With the shell. The washer is secured to the stem of the cock by means of a pin or'screw 14, which passes through the tongue and into ascreW-hole in the stem. There are two of the screw-holes made at IOO ninety degrees apart, so that the washer and tongue may be shifted in position.

Fig. l of the drawings shows the cock adjusted and adapted to be used asaright-hand cock. If it be desired to nseit as aleft-hand cock, it is inverted in position, the washer is detached from the stem, is shifted ninety degrecs, and is secured by the screw in the secon d screw-hole, the handle being also detached and shifted correspondingly and separately from the adjustment of the tongue. This changes the adjustment of the cock and adapts it perfectly to be used on the left-hand side. As before stated, the stops are formed symmetrically either on the front or back side of the cock-shell. We prefer, however, to form them on the back, since they are then not visible when the cock isin use and do not impair the neat appearance thereof.

The advantages of our invention will be appreciated by those skilled in the art. In addition to the ease of adjustment which it affords, the cock is of advantage, because it permits the use of any kind of handle, and the presence of the stops and tongue materially increases its strength.

3y reason of the fact that we combine with the detachable handle acock-shell constructed with the hole 8 at right angles with the line of the Water connections and adapted to register with the slot 6 in the plug, and the hole '7 in the plug extending substantially at right angles from the passage 6, our improved device is adapted not only for use interchan ably as a right or left hand cock, but it can be adjusted also to waste the water from the water-pipe at either side of the cock. This is of importance, especially when the cock is made and sold to the trade with its end portions 2 3 unsyminetrical, as if one be fitted for a brass or iron pipe and the other for a lead pipe.

As will be apparent, the cock may be modified in form and details of construction within certain limits. Thus, instead of having a single tongue or stop on the Washer and two stops on the shell, there may be two tongues on the washer and a single stop fixed to or made integral with the shell between the same. This modification we intend to cover by the following claim.

IVe claim as our invention-'- In a waste and stop cock having a plug rotary through an arc of ninety degrees, a slot 6, extending through the plug, a passage 7, leading therefrom substantially at right angles, opposite water connections 2 3, and a hole S, formed in the shell of the cock substantially at right angles to the line of the waterconnections and capable of registering with the slot 6, the combination, with such plug, of a detachable and adjustable handle, a collar set on a plug and movable therewith, said collar having a tongue adapted to be moved separately from the handle and adjusted in either of two positions ninety degrees apart, and stops on the shell to limit the motion of the tongue, substantially as and for the purposes described.

In testimony whereof We have hereunto set our hands this 24th day of August, A. D. 1891.
