A vacuum appliance capable of picking up both wet and dry material is described, wherein the vacuum appliance includes an impeller configured to induce liquid into the vacuum appliance, a motor configured to turn the impeller, a restrictor assembly to prevent the liquid from being ingested into the motor, and a bypass vent assembly configured to allow sufficient air to reach the motor in order to keep the motor cool while the restrictor is preventing the liquid from being ingested into the motor. The vacuum appliance also includes a drum configured to retain the liquid and an impeller intake between the impeller and the drum. The restrictor may comprise a float configured to rise with a level of the liquid in the drum and prevent the liquid from entering the impeller intake. The bypass vent assembly may be configured to allow airflow to bypass the restrictor and/or the drum.

Portable wet-dry vacuum cleaner

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.

Vacuum appliance having push and pull handles

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.

Combined wet/dry vacuum

Compound miter saw

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. In conjunction with the different relative positions of the powerhead, the horizontal bed is also adjustable to provide different woodworking operations. The powerhead is also adapted to be vertically adjusted in proximity to the horizontal bed while also be rotatably adjusted relative to the column for positioning the spindle in a horizontal and proximate position relative to the horizontal bed for cooperation with a separately mounted lathe tail stock and tool rest in operating the combination woodworking tool as a lathe.

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. Each of the stop rings includes an interference projection and the adjustment ring has a tab fixedly mounted thereon which extends to a point between the interfering projections. The stop rings may be fixed to the router base to limit the range of angular rotation of the adjustment ring.
