Abstract
Safety device for controlling a valve. For application to a valve for controlling fluid flow, there is provided a normally inoperative device which the operator must consciously and deliberately render operative before the valve can be changed from one setting to another. In the illustrated embodiment, a valve activating device is held in inoperative position by suitable resilient means. To render same operative, the operator pushes the operating device against such resilient means into engagement with a desired portion of the valve for effecting the desired operation. As shown, such operating means automatically disengages only in one selected position of the valve, such as the 'off' position, but remains engaged while the valve is in the other position, such as the 'on' position. It is, however, possible by a simple modification to render same automatically disengageable as the valve attains either position.
