Abstract: A motor driven power tool is provided having an internal dust collection system. A single electric motor drives the working member such as a saw or sander and simultaneously drives an air pump which acts as a collector vacuum for debris created when the power tool is in use. A dust collector shroud surrounds a portion of the cutting member and forms an outlet connected to the air pump inlet.

Abstract: An engine powered hand-held power tool and engine lubrication method is provided, the power tool being intended to be carried by an operator during use. The power tool has a frame, including a handle to be grasped by the operator, an implement affixed to the frame having a rotary input member, and a small four-cycle, lightweight, internal combustion engine attached to the frame for driving the implement. The four-cycle engine has a lightweight aluminum alloy engine block having a cylindrical bore and an enclosed oil reservoir formed therein. A crankshaft is rotatably mounted in the engine block for rotation about a crankshaft axis. A piston reciprocates within the bore and is connected to the crankshaft by a connecting rod. An oil splasher driven by the crankshaft intermittently engages the oil within the enclosed oil reservoir to splash-lubricate the engine.

Abstract: A compact, lightweight and easy-to-use wheeled lawn care unit comprising a two-wheeled carriage, a power source, plurality of tools which may be alternatively connected to the power source, a handle and a boom connecting the selected tool to the power source. The power source is pivotally connected to the carriage at a location within its footprint. The unit has a low center of gravity by placing the power source pivot and center of gravity within a cylinder defined by the wheels. The boom extends horizontally from the power source and is of a split boom configuration which allows selective rotation for the boom portions relative to one another. An edger that can be selected for the unit, which includes a spring-loaded wheel. The edger may be rotated from a non-working position where the edger blade does not contact the ground to a working position by rocking a handle behind the carriage forward against the bias of the spring. A second more compact version has the shield positioned on the boom.

Abstract: An apparatus for punching knock-outs out of light gauge steel framing studs used in building construction to form holes of sufficient size to allow building wiring and piping to extend therethrough includes a compact hand held frame (12) having a generally C-shaped frame portion (14). The C-shaped frame portion has spaced apart ends (16, 18) located along a working axis (20) for receiving a stud (30) therebetween. A punch and die assembly (24) includes a punch (26) and a die (28) mounted opposite each other at the ends of the C-shaped frame portion. An actuatable driving mechanism (36) mounted to the frame is operable to drive the punch and dic assembly over a working stroke range between a deactuated position (52) and an actuated position (54). In the actuated position, the punch extends into the die by punching through the stud to produce a knock-out (342).

Abstract: A line trimmer head (10) includes a line feed configuration which facilitates reloading the head (10) with new line without requiring removal of the spool (24) from the housing. Line (18) is sequentially fed first into the housing through a peripheral opening (20) in the housing, through a guide channel (84, 86) in the spool, and then out of the housing beyond a lower flange (26) of the spool through an opening in the hub (98) of the spool. Finally, the line is fed into a small opening in a spool flange (94) to secure the line with respect to the spool. Rotation of the spool then 46 causes the line to be drawn into the housing through the peripheral opening and wrapped around the spool. The spool provides separate storage compartments (38, 40) for different lines. Additional payout of line is provided when a bump knob is bumped on the ground surface.

Abstract: A blower nozzle (30) and a vacuum nozzle (40) extending in parallel with each other are connected to a main body (10) housing therein a fan (19) and a motor (20). The main body (10) is provided with a dust bag (50). In a vacuum mode, air is directly sucked from the vacuum nozzle and is introduced into the dust bag by the rotation of the fan. In a blower mode, the air similarly sucked from the vacuum nozzle is directed toward the blower nozzle.

Abstract: A disc sander having a scroll type vane pump embodied in a shroud enclosing the back side of a sanding disc. The inlet ports of the pump are coupled by a manifold to a location adjacent to the front face of the sanding disc at a location where the sanding dust and debris are generated. A tortious serpentine path is provided about the periphery of the pump housing which reduces pump noise and increases pump efficiency. The fins of the vane pump are provided on the back side of the sanding disc.

Abstract: Parallel tube type, gasoline powered, blower/vacuums with improved versatility are provided. In one possible feature, a flapper throttle adjacent to the housing for controlling the engine is pivotable from side-to-side with respect to an elongate handle. The elongate handle is sufficiently long to allow a plurality of gripping positions, while the flapper throttle is sufficiently long to allow the operator to access the flapper throttle from different gripping positions on the handle. In another possible feature, a pivotable lever throttle is provided at an interface of the handle forward portion and a transverse grip portion at the handle forward portion end. The lever throttle has a first end accessible to the operator when gripping the transverse grip portion, and a second end accessible to the operator when gripping the handle forward portion.
