Application filed July 28, 1928. Serial No. 296,060.
This im ention relates to improvements are tapped through bosses 11 on the end Wall. 55 in controlling devices for wells, and has for of the casing, theheadsbeing exposed to reits object to provid an improved device ceive a bar or other tool whereby the screws for capping wells to control or stop the flow may be turned. The inner ends of the screws therctrom. l l ith large and powerful wells are provided with a plain portion at 12 which it is often a matter oi diiiiculty to stop the extends loosely through slots 13 in the ends 60 flow therefrom, and the present invention is of the yoke H, so that the yoke can rock with designed to provide a valve with operating respect to the screws. The screws are held to devices comprising screws which are powerthe yoke by means of washers L and M at iul enough to draw the valve to closed posiopposite sides of the yoke, and nuts J on the tion under all. conditions of how and pres extreme end of the screws, and the surfaces of 65 sure. The device includes improved means the yoke bearing against the washers L and for fastening the controlling head to the well M are arched as at 14 to permit the rocking casing and firmly supporting the same in action. The side edges of the valve plate F 5 position at the top of said casing. are rabbeted as indicated at 15 to engage cor Other features of advantage will be apresponding guides G fastened to the under 70 parent from the following description and side of the top of the casing A and forming the accompanying drawings. guldes in which the plate F slides.
In the drawings, Fig. 1 is a front eleva- In use the control head is attached to the tion of the device; Fi 2 is atop plan view; top of the well casing by means of the con- Fig. 3 is a section on the line 33 of Fig.2; nectmg collar G. Then by turning the screws 75 Fig. 4 is a detail in cross section.

This casing has at the bottom a amount of looseness to enable the valve to or collar I) which screws thereon, and the ful, and enable the valve to be closed against lower end of this ring has an up turned heavy flow or pressure. The screws of course threaded flange 7 which screws into a collar may be advanced to open the valve as desired.

The top wall of the casing A is flat, except It may also be noted that the casing A is for a neck 8 threaded to receive a cap E by cast in one piece without joints which might means of which the well may be sealed if deleak, the necessary connections being screw sired. threaded on the casing neck.
