Abstract: A drop cord extension light having a light assembly with a grippable handle portion and a lamp and reflector swingably mounted thereto. A support swingably mounts the handle enabling the light and reflector to be rotated in mutually orthogonal directions relative to the axis of rotation of the support. A clamping/stand assembly has a pair of arms swingably mounted to opposite ends of the support. Torsion springs are also swingably mounted to the support and in a first position clamp the support arms together and in a second position release the support arms so that they may be swung open to assume an inverted, V-shaped configuration serving as a support stand for the lamp assembly. The lamp may be swung to a position between the arms of the support stand when not in use and an extension cord wrapped about the arms and the lamp assembly thereby storing the electric cord in a neat, compact manner and further encircling and protecting the lamp and reflector.

Abstract: A brush with an automatic water control valve is disclosed. The brush includes a handle portion pivotably connected to an actuation portion and rigidly attached to a brush portion. A fluid passageway is provided through the handle portion into the bristles of the brush. Communicating with the fluid passageway is the flexible tubing which is adapted to be connected to a water fluid source under pressure. A valve is provided for opening and closing the passageway formed by the tubing and for providing flow through the passageway to the brush portion. The valve is actuated by a pivoting motion of the actuation portion with respect to the handle portion. The valve includes a roller which engages the flexible tubing and squeezes same, such that the normal rest position of the actuation portion with respect to the handle portion closes the tubing.

Abstract: A cleaning implement is provided with an internal valve for automatic water shut-off which can be regulated by hand. The implement connects to a conventional water supply, for example, a garden hose. When the valve is open, water is supplied through a removable sponge or brush to a surface to be cleaned. The valve is opened when two portions of the implement are pivoted with respect to each other. This can be done by pressing the sponge or brush against a surface to be cleaned, pivoting the two portions of the implement and thereby opening the valve. Alternatively, the two portions can be held by handles, one in either hand, and pivoted to open and close the valve. An opening is provided in the brush or sponge to allow water to stream from a nozzle to the surface to be cleaned, unobstructed. A soap dispenser is also incorporated into the implement. The nozzle and soap dispenser direct fluid from the user when the implement is held in the hands. The implement may be used with other fluids not water.

Abstract: Air pumps particularly suitable for use with bicycles includes a first elongated tube to form a pump chamber and housing, a second elongated tube coupled with a piston in the first tube to reciprocate the piston within the pump chamber. A flexible hose extends from the piston and through the second tube and has at its exposed end an air valve coupling. The first and second tubes are releasably secured to permit use of the pump as a seat post. The pump includes a first valve on the outside of the piston between atmosphere and a closed end of the pump chamber and a second valve inside the piston between the closed end of the chamber and the flexible hose. The first valve is configured to provide greater seal effect as pressure builds in the closed end of the pump chamber.

Abstract: An air pump particularly suitable for use with bicycles includes a first elongated tube forming a pump chambe and housing, a second elongated tube coupled with a piston through a connecting rod to reciprocate the piston within the pump chamber, and a flexible hose pneumatically coupled at one end with an air passage extending through the piston and having at its opposing end an air valve coupling. The first and second elongated tubes have outer diameters of a size permitting them to be received in and clamped by a seat tube collar of a bicycle frame and the seat post collar of a seat of the bicycle. The piston includes an annular sliding valve member used with a tapered annular valve seat which permits air compression to pressures of about 200 psi while preventing blowby. A second valve along the air passage prevents back flow. The elongated tubes are fixedly secured together in a releasable fashion to prevent relative axial motion or rotation, permitting the use of the pump as a bicycle seat post.

Abstract: A valve for fluids with a fluid conduit having a first and a second end. A baffle within the conduit has a first face oriented towards the first conduit end and a second face oriented towards the second conduit end. A baffle seat within the conduit between the baffle and the second end is arranged so that when the second baffle face rests against the seat fluid flow through the conduit is substantially blocked. An operating element, preferably a rod, is moveable relative to but capable of bearing against the baffle to separate the baffle from the baffle seat.

Abstract: A brush with automatic water shut-off is disclosed. The brush includes a handle portion pivotally connected to a body portion with a valve chamber intermediate to control water flow through the brush. A flutter valve is loosely positioned within the valve chamber and is continuously biased toward the valve chamber seat by the water pressure. An operating rod is movable within the body portion and extends past the plane of the seat. When the brush is not in use, water pressure forces the flutter valve toward the seat and contact between the flutter valve and the operating rod causes the body portion and handle portion to be pivotally offset with no water flowing. When the brush bristles contact the surface to be cleaned, the body and brush portions are urged into axial alignment about the pivot whereby the operating rod will force the flutter valve off of its seat, thereby automatically causing water flow through the brush.

Abstract: An improved derailleur shifter is disclosed which includes a pivot arm secured to the frame of the bicycle in a stationary relationship, a shifter arm pivotally secured to the pivot arm in a manner to rotatively move relative to the frame, a chain slide attached to the shifter arm in a rotative and angularly adjustable engagement, a spring biasing between the pivot arm and the shifter arm to continuously urge the chain slide against the upper run of the bicycle chain to depress the chain; a stabilizer interconnected between the pivot arm and the shifter arm in a manner to allow substantially unrestricted counter-clockwise pivotal movement of the shifter arm relative to the pivot arm and to restrict clockwise pivotal movement of the shifter arm relative to the pivot arm, and a flexible cable interconnecting the shifter arm with the derailleur whereby the derailleur will be automatically operated to index the chain across the small diameter cluster gears in response to pivotal movement of the shifter arm as cau

Abstract: An automatic shifter for a derailleur is disclosed which includes a pivot arm secured to the frame of the bicycle in stationary relationship, a shifter arm pivotally secured to the pivot arm in a manner to rotatively move relative to the frame, a follower attached to the shifter arm in rotative engagement, an operating spring biasing between the pivot arm and the shifter arm to continuously urge the follower against the upper run of the bicycle chain to depress the chain; a stabilizer interconnected between the pivot arm and the shifter arm in a manner to allow substantially unrestricted counter-clockwise rotation of the shifter arm and to deter or restrict clockwise rotative movement of the shifter arm and a flexible cable interconnecting the shifter arm with the derailleur whereby the derailleur will be automatically operated to index the chain across the small diameter cluster gears in response to rotational movement of the shifter arm as caused by interaction of the bicycle chain and the follower.
