Abstract: The present invention is a drain adapter for adapting a flushing device to a drainpipe. The adapter has a main body including an indent portion for retaining the flushing device during operation. The main body also includes an enlarged portion. The enlarged portion corresponds to a sink recess and expands under pressure to retain the adapter within the drainpipe.

Abstract: A mechanism for minimizing shock in a fluid has a housing, a valve disposed in the housing for regulating a flow of the fluid, a spring that urges the valve to oppose the fluid flow, and, a reservoir disposed in the housing downstream of the valve. The valve meters the flow of fluid from the reservoir if the valve moves in reaction to the flow of the fluid.

Abstract: A plunger caddy assembly includes a plunger and a caddy that receives the plunger. The plunger is selectively rotatable in a first direction relative to the caddy to release the plunger from the caddy. The plunger is selectively rotatable in a second direction relative to the caddy to secure the plunger within the caddy.

Abstract: A fluid delivery control system including a rotatable flow control member to provide a flow control signal to a controller and a rotatable temperature control member to provide a temperature control signal to a controller.

Abstract: A faucet assembly is operable automatically or mechanically to facilitate control in a non-powered or motor failure condition. In the automatic control position, separate and automatic control of fluid flow and temperature is provided by respective actuation of first and second handles. In the manual control position, the first and second handles are moved axially to decouple electric motors from corresponding fluid control valves. Such axial movement of the first and second handles concurrently couples the handles mechanically to the corresponding fluid control valves to provide the desired manual actuation.

Abstract: A valve system including a manual control mechanism configured to move a valve member.

Abstract: A fluid mixer including a mixing element configured to separate and mix hot and cold water streams.

Abstract: An electronic proportioning valve for connection to a cold water source, a hot water source and a mixed water outlet and for providing a mixed water of a desired water temperature and flow rate to the mixed water outlet.

Abstract: A fluid mixer including a pair of inlets configured to impart a rotational fluid flow and a mixing element configured to facilitate fluid mixing streams.

Abstract: A fluid delivery apparatus including an energy harvesting device to generate energy for communicating with a fluid control device.

Abstract: A coupling assembly for a portable drain cleaning machine includes a polygonal adapter mounted to a motor output shaft through a threaded interface. A polygon adapter threads over the motor output shaft in a locked male/female relationship to transmit rotation therebetween. A polygonal outer segment of the polygonal adapter telescopes into a polygonal inner segment of a sleeve mounted to the drum. The sleeve slides into a fixed cylindrical member and over the polygonal adapter to removably mount the drum. Rotation of the motor output shaft rotates the polygonal adapter which rotates the sleeve and the drum.

Abstract: A snap latch drum release assembly includes a multiple of latches which engage the inner diameter of a plate spaced away from a rotary drum to lock and unlock the rotary drum of a drain cleaning machine without the need for tools. As the latches engage a plate on the drum, no shaft grooves are located in the shaft to weaken it. The snap latch drum release assembly is mounted on a support frame assembly. Lifting of an actuating handle engages pins in the latch surfaces to overcome their spring bias and simultaneously drive the latches away from the plate to allow release of the drum. To mount the drum, the drum shaft is pushed into the sleeve and the latches are received onto the latch plate.

Abstract: A socket latch drum release assembly includes a shaft release coupling which telescopically engages a rotary drum shaft to selectively lock and unlock a rotary drum of a drain cleaning machine without the necessity of tools. The shaft release coupling includes a polygonal shaped distal end which corresponds with a polygonal opening in the removable drum shaft. At least one of the plurality of faces which form the polygonal shaped distal end includes a retractable engagement member which corresponds to a recess located in each face of the polygonal opening. The drum shaft is directed into the sleeve from one side and the shaft release coupling is engaged with the shaft on the opposite side of the sleeve. Engagement between a radially extending flange of the shaft release coupling and the end of the shaft rotatably locks the rotary drum shaft into the sleeve.

Abstract: A rotary drum release assembly includes a multiple of lock pins which engage a rotary drum shaft to lock and unlock a rotary drum to a drain cleaning machine without the need for tools. The rotary drum release assembly is mounted within a support frame assembly. A rotary drum shaft groove is located within a sleeve mounted to the support frame assembly to minimize localized weakening of the shaft. Rotation of an actuating handle engages cam surfaces with the lock pins to overcome their spring bias of the lock pins and simultaneously drive the lock pins away from the shaft to allow release of the drum. To mount the drum, the drum shaft is pushed into the sleeve and the lock pins are received into the shaft groove.
