Abstract: A backflush filter cleaning system for use with a vacuum cleaner employing an internal filter may include a filter cage having a first end, a second end and a peripheral opening, a backflush valve coupled to the first end, an intake plenum coupled to the second end, the plenum having an air outlet, an inlet valve coupled between the peripheral opening and the air outlet, and a cleaning actuator coupled to at least one of the valves. The system can be adapted to clean a filter coupled to a vacuum cleaner where the system can include a means for establishing a first airflow path from inside the collector through the filter, to the vacuum source, a means for flowing air along the first airflow path, and a means for establishing a second airflow path from an atmosphere surrounding the vacuum cleaner through the backflush valve, through the filter, and into the collector to clean the filter.

Abstract: The present disclosure provides a method and system to supply pumping capabilities to a wet and dry vacuum cleaner. A single motor can operate a vacuum unit and the pump distinct from the vacuum unit. A port in the vacuum flow path can act as a vacuum tap to prime the pump when necessary. The pump can directly pump the fluids without having to flow first into the drum container of the vacuum cleaner. The system can allow independent operation of the vacuum unit and the pump and at different, more optimal speeds for each, allowing a higher performance on each of the vacuum unit and the pump, since maximum power for the system can be provided to either the operating device while the other one is not operating. Accordingly, the disclosure further provides a system and method for separately engaging and disengaging the vacuum unit and the pump.

Abstract: A vacuum cleaning appliance includes a vacuum cleaner drum having a bottom wall, a sidewall, and a rim surrounding an open upper end with a lid detachably mounted to the rim and extending across the open upper end of the vacuum cleaner drum. A motor powered blower is at least partially received within the lid for creating a vacuum in the drum. A first handle is connected to a first side of the vacuum cleaner drum or the lid and may be used for pushing the appliance in a direction of travel, and a second handle is connected to a second side of the drum or the lid generally opposite the first side for pulling the appliance in the travel direction. One or both of the handles may include mechanisms for securely and easily mounting the handle to the lid or the drum of the vacuum.

Abstract: The present invention is a handle used for pulling a wet/dry vacuum appliance and a mechanism for securely mounting such a handle to the lid of the vacuum. The mounting mechanism is designed for ease of assembly and reduced fastener cost. The handle is attached at two of its four attachment points by inserting journals molded into the sides of the handle into open bearing pockets molded in handle receiving recesses on the lid of the vacuum. The handle is then rotated into place and secured at the remaining two attachment points with suitable fasteners, such as screws. In certain embodiments of this invention, when the handle is rotated into position for attachment a locking slot in the bottom surface of the handle engages a rib provided in the handle receiving recess of the lid. This rib guides the handle as it rotates, prevents the journals from sliding back out of the bearing pockets, and locks the handle into the proper position for insertion of the fasteners.

Abstract: A combination woodworking tool is disclosed. The combination woodworking tool includes a frame having a horizontal bed for supporting workpieces. A rigid column is supported by the frame in proximity to and extends vertically upwardly beyond the horizontal bed. A powerhead is mounted to an upper end of the column in overlying relationship to the horizontal bed, the powerhead being vertically adjustable for movement toward and away from the horizontal bed. The powerhead further includes a motor and spindle which extends below a lower end of the powerhead. The spindle is adapted to interchangeably receive a chuck for use with a drill or a collet for use with a router. The powerhead is adjustably and rotatably mounted relative to the column for positioning the spindle in predetermined vertical, angular or horizontal positions relative to the horizontal bed for vertical, angular or horizontal drilling or routing.

Abstract: A portable electric router having a depth of cut adjustment mechanism including an adjustment ring which engages a screw thread on the motor housing and rotationally engages the router base. There is further provided an arrangement for preventing relative rotation between the motor housing and the base. The adjustment ring is formed as a split ring with projections adjacent opposite sides of the split, each with a frusto-conical camming surface. A circular clamp knob mounted for threaded rotation on a bolt passing through the projections radially with respect to the router motor housing bears against the camming surfaces so as to squeeze the ring in order to effect a clamping action as the knob is moved inwardly. In order to provide limit stops for preset depths of cut, a pair of stop rings are provided which are angularly rotatable on the router base.

Abstract: A sander with a removable auxiliary handle. The auxiliary handle is formed from three pieces (two mirror image body halves and a resilient latching finger) and slides and snaps onto grooves molded as part of the front end of the sander housing.
