Abstract:
A hydrant for delivery of water from a hot and a cold pressurized source, comprising,a fluid inlet pipe having forward and rearward ends, a fluid closure valve in the rearward end of the inlet pipe, a fluid outlet port connected to the forward end of the inlet pipe, an elongated valve rod extending through the pipe and having a rearward end connected to the fluid closure valve, and a forward end terminating in a plurality of splines, a hollow fitting secured to the forward end of the inlet pipe and receiving the forward end of the rod, a rod operating-handle in an outward end of the fitting and having a shoulder longitudinally slideably mounted in the fitting, a plurality of spline grooves in the shoulder adapted to slideably receive the splines on the forward end of the rod in a first position of longitudinal movement, and being adapted to disengage connection with the splines on the forward end of the rod in a second position of movement in an opposite direction, and a spring between the shoulder and the fitting to normally hold the spline grooves in a condition of disengagement, but to permit the splines and the spline grooves to be operatively engaged when the operating handle and the shoulder are slideably moved to the first position to compress the spring, whereupon rotatable movement of the operating handle in the first position will rotate the rod to open the closure valve.
