Abstract: Disclosed is a diaphragm valve. When a chamber is expanded by fluid supply into a pipe-shaped button, a valve stem is slightly moved upward by a rod and a shaft to open an outlet of an orifice. Fluid received in a space between a cap and a diaphragm and having a high pressure is discharged into an outlet-side space, whereby the diaphragm opens a guide conduit. When fluid is discharged from the pipe-shaped button, the diaphragm is moved toward the guide conduit, and the valve stem closes the outlet. The fluid in the inlet-side space has a high pressure, and the fluid in the space between the cap and diaphragm has a low pressure. The high pressure fluid flows toward the low pressure fluid through a pilot hole of the diaphragm. When fluid pressure balance is effected between the spaces, the diaphragm closes the guide conduit.

Abstract: An automatic shut-off valve for installation on a swimming pool or spa main drain. The automatic shut-off valve has a ball and ball spring between a diaphragm and a housing. The diaphragm is made of resilient material. Downward force on the diaphragm urges the ball into sealable engagement with a valve seat in the housing. During operation, a swimmer covers sufficient diaphragm base apertures so that the diaphragm center is moved downwards as urged by the main drain suction, towards a swimming pool or spa main drain over which the automatic shut-off valve is mounted. The downward motion of the diaphragm urges the ball into sealable engagement with a valve seat in the housing, where it is securely held by the main drain suction. In this fashion, the ball is entrapped instead of the swimmer, thus avoiding possible disembowelment and/or drowning on the part of the swimmer. Back-up shut-off function is provided by a cap spring-loaded into a closed position whence it migrates should the ball become dislodged.

Abstract: An automatic shut-off valve for installation on a sing pool or spa main drain. The automatic shut-off valve has a soft gasket, ball, and ball spring between a grate and a housing. The grate is free to reciprocate up and down relative to the housing. Downward reciprocation of the grate urges the ball into sealable engagement with a valve seat in the housing. During operation, a swimmer covers sufficient grate apertures so that the grate is moved downwards as urged by the main drain suction, towards a swimming pool or spa main drain over which the automatic shut-off valve is mounted. The downward motion of the grate urges the ball into sealable engagement with a valve seat in the housing, where it is securely held by the main drain suction. In this fashion, the ball is entrapped instead of the swimmer, thus avoiding possible disembowelment and/or drowning on the part of the swimmer.

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.

Abstract: A water saving device, implemented as a pair of spring loaded, normally-open shutoff valves inserted into the hot and cold water supply lines of a faucet, which are connected via a cable mechanism to a foot actuator. Actuating the mechanism causes the shutoff valves to close, interrupting any flow of water in the supply lines. Releasing the mechanism allows flow to resume. The shutoff valves are installed in series upstream of the normal hand-operated faucet valves. The user starts the water flow and adjusts the temperature of the water in the normal manner using the hand-operated faucet valves. When the user wishes to temporarily stop the water flow he or she steps on the foot pedal, thereby causing the shutoff valves to close. When the pedal is released the shutoff valves open and the water flow resumes at the same flow rate and temperature previously set by the user.
