378,730. Fluid-actuated valves. HALL, C., 63, Calle de Amberes, Mexico City. Nov. 28, 1931, No. 33055. Convention date, Oct. 14. [Class 135.] A fitting for attachment to manually-actuated valves of the " rising stem " type to enable them to be closed from a distance comprises a member associated with a pair of actuating pistons and adapted tc co-operate with the outer end of the valve spindle after the normal actuating mechanism has been removed. The pistons 17 work in cylinders 16 joined by a bridge 28 and mounted on a baseplate 33 secured by bolts to lugs 14 from which the yoke supporting the existing hand-wheel has been removed. The piston-rods 19 are joined by a bridge 22 to which a socket 15 engaging the end of the valve spindle 4 is secured by a nut 30. The valve is opened by means of a twopart hand-wheel 22 clamped about the screwed spindle 4 and bearing against a two-part collar 23 resting on the valve casing. After the removal of the hand-wheel the valve may be closed by admitting fluid pressure from a pump through a conduit 18. The fluid pressure is released, to permit manual opening, by valves 21.
