Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.

Abstract: A hydraulic valve for controlling the flow of a pressured liquid with a housing that has an inlet and an outlet with a pivotally mounted handle that actuated a valve stem member housed within an internal bore with a counter bore step surface. An O-ring member is mounted on the step surface that comes in contact with a convex surface provided in a peripheral flange member on the stem member. A compressible cylindrical member is trapped partially within an opening at one end of the valve stem member urging the convex surface against the O-ring thus blocking the flow of the pressurized liquid through the internal valve bore.

Abstract: Improvements in service valve heads which may be connected to soft drink bottles or the like, wherein a valve body is obtained, a liquid circulation channel being provided between the spout and the fishing tube, said channel having a check valve. The rod of said valve is actuated by a command means whose the articulated arm is foldable over the valve body, having folding stops and having a strap provided with a retainer. Folding stops of the valve body and corresponding recesses of the articulated arm prevent that the latter being lowered by any accidental pressure, in which case the valve rod would be displaced and an unwanted release of liquid would be produced. For delivering the carbonated liquid it is first necessary to release the folding strap. In this way the articulated arm may be unfolded until it displaces through the command channel existing on the head walls.

Abstract: The actuating lever of this invention is intended for use with an air valve having a normally extending valve stem. The actuating lever has utility in many fields. One illustrated embodiment is described in association with an air valve in the waste removal system of a sewing machine, wherein it is desired that the air valve be activated before the sewing machine is activated by depression of a treadle. It is normally desired to initiate the flow of compressed air to create a suction for the removal of waste generated by operation of the sewing machine before the sewing machine is started. The configuration of the actuating lever provides a mechanical advantage that, in the illustrated embodiment, enables the valve stem of the air valve to be depressed with less pressure on the treadle than was required in the prior art, and with less pressure than is required to start the motor of the sewing machine.
