N 0. 908,717. Specification of Letters Patent.

Patented Jan. 5, 1909. Application filed May 21, 1908. Serial N 0. 434,038.

To all whom it may concern: 1 so that they may readily withstand the stress Be it known that I, WILLIAM G. l/VEST exerted thereon in opening and in closing the WATER, a citizen of the United States, residl valve from the surface.

ing at Columbus, in the county of Franklin As seen, the valve 9 is tapered, and has and State of Ohio, have invented certain new the opening 10 therethrough which is adapted, when the valve is properly 1positioned, to

register with the inlet and out t openings 2 My invention relates to improvements in g r and 3, and when the valve is turned through the stop coch used especially at the curb J a quarter revolution, the communication bewhere the pipmg. for a dwelling or other tween the inlet and outlet pipes is effectubuilding is connected with the pipe tapping l ally to ed. To assure the turning of the the main Water line, and consists in a coilvalve through the proper angle, and further struction having a wing stop for the valve to make it certain that the valve will not be formed at the lower end thereof, and the rotated too far, I provide upon the lower end valve being so constructed as to receive the of the shell 1 the arc-shaped depression 11, wing stop in a manner permitting the said which is formed to extend over approxistop to be separated therefrom, and to be mately one-half of the circumference of the held in place by the bottom screw cap. This g lower end of the shell 1, and at the ends of arrangement removes the stop entirely from this depression the shoulders 12 and 13 are any danger of being clogged with earth or formed. The valve is recessed preferably at other loose material, and renders the manuthe middle of its lower end as shown at 14, facture of the valve much more simple and the said recess being preferably formed with inexpensive, and at the same time providing a rectangular shape. A detachable member a construction which is very easily repaired, constructed to fit the recess 14 is provided and at the same time is made of a great with the arc-shaped wing 16, when thememstrength. 1 her 15 is positioned in the recess 14, the arc- In the drawings which are hereto attached shaped wing 16 extends into the depresand hereby made a part of this specification, sion 11, and as the valve is rotated, the said Figure 1 is a section along the axis of the wing will engage ashoulder 12 or 13, dependvalve and easing showing the parts in place; 2 ing upon the direction in which the rotation Fig. 2 is a bottom plan view; Fig. 3 is a view takes )lace, provided the rotation extends of the stop carried by the valve, detached. i throug 1 a sufficient distance. The operator Referring to the drawings in which the 5 therefore rotates the valve until the wing same numeral indicates the same part engages a shoulder, and therefore knows which the following is a specification.

throughout, 1 is the shell or casing for the whether the valve has been completely valve containing the inlet 2 and the outlet 3, opened or completely closed whichever may internally threaded to receive the pipes be desired. When the member 15 has been through which the water is conducted; 4 is thus positioned in the lower end of the valve, the extension at the lower end of the casing the bottom cap member will then be screwed internally threaded and adapted to have apinto place, whereby the member 15 will be plied thereto the bottom cap 5, and when held in engagement with the depression 14;. this cap is in place the valve at this end is When it is desired to repair the valve, or for effectually secured against any earth or de any reason to disassemble the parts, the ca bris of any sort which might interfere with members are removed, and the member 15 1s the proper operation of the stop construcdetached, whereupon the valve may be readtion. ily removed from the shell 1. The parts may At 6 is shown the turn key for the valve also readily be assembled, when the valve is securely positioned by means of the set to be put into operative position. screw 8; the top cap is shown at 7. hen The advantage in manufacture of a valve the valve is positioned for operation, it is J constructedin accordance with my improveusually several feet below the surface and a ments is very great, inasmuch as it is much long rod provided at its lower end with a cheaper and easier to form the wing stop member to engage the key 6 is let down and separately than it is to form it as a portion of turned from its upper end, so that the force the valve, and its ready detachability renders exerted upon the valve is very great, and the the assembling and disassembling of the parts in my construction may be very strong parts easy and rapid.

What I claim is:

1. In a stop cock comprising an inclosing shell .and a valve therein, means for rotating said valve at one end thereof, said valve having a socket formed in its 0 posite end, a member movable With said va ve adapted to be positioned in said socket and having an integral radial flange thereon, shoulders on said shell to engage said flange, anda removable cap adapted to maintain said member in said socket.

2. In a stop cock comprising an inclosing shell and a valve therein, said valve having a socket formed in one end thereof, operating means for said valve at one end thereof and controlling means at the opposite end comprising stops on said shell, a member adapted to be positioned in said socket having an integra radial flange thereon for en gagement with said stops, and a removable cap ada ted to be applied to said shell to retam sai member in said socket.

In testimony whereof I afiiX my signature in the presence of two-witnesses,
