Abstract: A solution bottle in a toilet flush tank, connected with a nipple fitting having respective pathways for water and cleaning solution to mix together.

Abstract: A control apparatus including a pilot valve projecting through a passage in a control diaphragm to be formed with an enlarged poppet to seat the underside of the diaphragm and formed with a poppet head shaped to direct incoming flow away from the pilot passage to minimize entry of residue.

Abstract: A tube device including concentric inner and outer tubes to form an annulus to receive an upright stem in a toilet tank and adjustable relative to the stem. A keeper limits travel of a float to prevent opening of a control valve absent flushing of the toilet. In one aspect, the present invention includes an elongated catch device pivotally mounted intermediately to an inlet tube device and carrying at its upper extremity a keeper selectively disposed in the path of a float device to, unless a toilet has been flushed, block lowering of the float device and consequent opening of the control valve.

Abstract: In one aspect, a tube device including concentric inner and outer tubes to form an annulus to receive an upright stem in a toilet tank and adjustable vertically and rotationally relative to the stem. In another aspect, an elongated catch device is pivotally mounted intermediately to an inlet tube device and carries at its upper extremity a keeper selectively disposed in the path of a float device to, unless a toilet has been flushed, block lowering of the float device and consequent opening of the control valve.

Abstract: There is disclosed a faucet of the "washerless" construction employing a spherical valve member in a hemispherical valve body in which the spherical valve member has only a single protruding tubular member that serves both as the valve member operator and the discharge nozzle for the faucet.

Abstract: An extendible ballcock assembly including a support pipe threaded at its lower end for partial receipt in a support fitting.The support fitting furthermore includes a peripheral cavity in the upper end thereof adapted to receive a toroidal seal. The seal includes a threaded interior surface conformed to the support pipe threads and is compressed into the fitting by a compression nut. At the upper end the support pipe terminates in a valve assembly which includes antisiphoning provisions.

Abstract: There is disclosed a liquid level control valve ideally suited for water closets and the like that employs a submersed liquid pressure responsive diaphragm as an actuator for the control valve. The control valve is supported in the tank on a liquid inlet vertical column, above the normal, controlled liquid level thereon. The control valve has a flexible valve closure member that subdivides the control valve housing into main and secondary chambers. A small orifice provides liquid communication through the diaphragm between the chambers and the secondary chamber is provided with a bleed orifice in the housing wall with a closure member therefor carried on an actuator arm which is mechanically coupled through a vent pipe to the diaphragm actuator.

Abstract: A diaphragm controlled toilet bowl valve of simple construction that is substantially silent in operation, will not permit water to be siphoned from the tank in which it is disposed during an emergency in which the pressure of water in the supply lines decreases substantially, and one in which the actuating float is easily adjusted without hindering or deforming the rod on which it is supported.
