Abstract: A vacuum apparatus includes a holding tank, a vacuum source, and a docking station. The tank holds material and has an interior and an exterior. The vacuum source draws the material from the exterior into the interior of the tank. The docking station docks a pump on the exterior of the tank so that, when the pump is docked in the docking station, the pump may be used to pump material out of the tank and so that the pump may be detached from the docking station for stand alone use.

Abstract: A retainer for a portion of an electric power cord includes a guide that guides the cord into a space between a pair of ears that cooperate with a grooved part of a handle to define two V notch passageways for the cord leading the cord into a groove which wraps around the handle. The floor of the guide defines with the groove a path for the cord past the ears which is substantially in a plane.

Abstract: A liquid sprayer includes a housing with a spray outlet, an electric pump switch which is movable to operate a spray generating pump and a manual grip defined on the housing. A main switch is moveable linearly along the housing between on and off positions, which operate the electric switch to respectively cause and stop pump operation. A safety actuator is movable to block and permit movement of the main switch. The safety actuator has a grippable portion biased to extend outwardly from the housing. To operate the pump switch, a user squeezes the safety actuator into a switch on position in which the safety actuator releases blocking engagement with the main switch, and thereby allows the main switch to be moved to its on position which operates the pump switch to operate the pump.

Abstract: The invention concerns an air blower including a centrifugal fan which is driven by an electric motor. The blower has a two-part blower housing comprising an upper housing which encloses the motor beneath the motor cap and a lower housing. The centrifugal fan is disposed in the chamber between the upper and lower housing. The plenum around the fan leads to an outlet from the blower. An intake shield extends across and blocks undesired entrance of objects into the inlet opening in the bottom of the lower housing. The blower may be seated on a lid across an opening in it. An adapter in the lid receives the intake shield and has its own air inlet to the blower. The orientation of the blower with respect to the lid is rotatable. Cooperating flanges on the blower and the adapter hold the blower to the lid at two rotative locations and a button latch arrangement latches the blower at each of the two arrangements. Between the two latched orientations, the blower may be lifted free of the lid.

Abstract: A dolly for supporting a tank standing on end is provided with a T-shaped plastic base formed by a crossarm and a leg that are joined by an adjustable interlocking connection. Both ends of the crossarm and the end of the leg remote from the crossarm are provided with arcuate grooves that receive the bead surrounding the bottom of the tank. The heads of fastening screws extend over the grooves to retain the bead therein. A metal axle rod extends through a longitudinal passage in the crossarm. This passage has an open top in the region between the grooves in the crossarm so that a tank on the base engages the rod to be supported directly thereby.
