Abstract

250,118. Ashley, W. E., and Mosby, S. W. Oct. 23, 1925. Actuating-mechanism.-A parallel slide stop valve of the type actuated by rack and pinion gear is operated by a detachable key h, Fig. 3, having a projection h<1> which passes through a slot g<3>, Fig. 2 in an inturned flange g<2>, Figs. 1 and 2, so that by engagement under the flange the key cannot be removed until it has been brought to the closed position of the valve. In such an arrangement, according to the invention, stops i, i<1>, Fig. 2 are provided below the flange g<2> for co-operation with the projection h<1> to limit the turning movement of the key in either direction and thereby the amount of movement of the valve.
