In a pneumatic-powered tool, a flow of air along a first or second flow path may be controlled by a position of air inlet guide surfaces of a rotatable valve relative to air inlet guide slots of a fixed valve sleeve. Air flowing along the first flow path may rotate a motor in a first direction to operate the tool in a forward mode. Air flowing along the second flow path may rotate the motor in the second direction to operate the tool in a reverse mode. In the forward mode, as air flows along the first flow path, air may be discharged along a primary discharge path, with a portion of the second flow path providing a secondary discharge path. In the reverse mode, as air flows along the second flow path, air may be discharged along the primary discharge path, with a portion of the first flow path providing the secondary discharge path.

A power tool (e.g., a pneumatic tool) includes a tool housing, a motor disposed in the tool housing, and a switch coupled to the tool housing and configured to control operation of the motor. A light unit includes a light unit housing removably coupleable to the tool housing. The light unit includes a light disposed in the light unit housing, a controller, and a sensor. The sensor is configured to sense actuation of the switch, and the controller is configured to cause the light to turn on when the sensor senses that the switch is actuated.
A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof. The system also uses an anchor which includes a sleeve and a plug. The sleeve includes at least two legs extending toward a first end of the sleeve. The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

ARRANGEMENT FOR CLAMPING AN ACCESSORY TO A POWER TOOL
A clamp arrangement for releasably securing an accessory to an oscillating power tool can include a tool body including a motor that drives an output member. A clamp assembly can include a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp member of the clamp assembly is offset from the accessory permitting removal of the accessory from the clamp assembly. A lever can have a user engagement portion and a pivot portion including a pivot axle. The lever can be pivotally coupled to the tool body about the pivot axle between a first position, wherein the clamp assembly is in the closed position and a second position wherein movement of the user engagement portion of the lever causes the clamp assembly to be moved to the open position.

HOLE CUTTER WITH AXIALLY-ELONGATED APERTURE DEFINING MULTIPLE FULCRUMS
A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially- elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.
A power tool for cutting vegetation is disclosed. The power tool includes interchangeable cutting elements that can be readily attached and detached from a main body portion without any preliminary alignment steps. The main body portion of the power tool includes a selectively actuatable motor including a rotary output and a rotary drive element including a resiliently biased drive pin. Blade carrier assemblies are capable of being selectively and removably attached to the main body portion and each include a moveable blade portion having a drive pin slot. Upon attaching a blade carrier assembly to the main body portion and actuating the motor, the resilientl biased drive pin is rotatable to a position such that the drive pin is resiliently forced into the drive pin slot of the working piece to actuat the working assembly.
SEALED THERMOSTAT SUB-ASSEMBLY ABSTRACT OF THE DISCLOSURE A kettle having a thermostatic sensor to limit boiling of the kettle by switching off the kettle heating element upon the occurrence of boiling is provided with a thermostat sensor sub-assembly including a thermostatic switch secured within a split housing, having an interior O-ring seal to isolate the sensing portion from the electrical components, and an external O-ring seal serving to hold the sub-assembly in assembled relation, and to secure and seal the remote end portion of the assembly within its housing in the kettle.
ELECTRIC KETTLE ABSTRACT OF THE DISCLOSURE An electric kettle is provided with a thermostatic simmer control or boil cut-out wherein the thermostatic element is located above the top of the kettle adjacent the open spout aperture, the kettle being provided with a steam diverter scoop extending into the spout opening, to intercept the uppermost portion of live steam flowing towards the spout opening and divert it rearwardly into heating relation with the sensing bulb of the thermostatic element. The thermostatic element is housed within a fore part of the handle, which also serves to conceal the wires connecting the thermostatic element with the electrical components located in the bottom of the kettle. The arrangement permits the use of a coarsely calibrated thermostat.
POWER PIERCE CAN OPENER ABSTRACT OF THE DISCLOSURE An electric powered can opener has a housing, a feed gear that is motor connected and rotatably mounted to drive and rotate a can while holding it by its rim. An operating lever is pivoted above the gear on the housing and carries a cutter mechanism to remove the can lid. To this conventional arrangement an improvement is added to the cutter mechanism of a gripping structure connected to and movable by the lever with the gripper lying on a line between the lever pivot and the top of the feed gear and disposed to contact the can rim top ahead of or before the cutter contacts it so the gripper bites into the rim on lever rotation toward the can and then pulls the cutter into the can top providing a power pierce. The lever is preferably spring-biased for rotation toward the can at all times and has a slidable switch actuator that is linkage-connected to the lever for manual operation.
B67B 7/70 - Cutting devices, i.e. devices including at least one cutting element having one or more cutting edges for piercing through the wall of a closed container, e.g. can openers including an annular, driven, wheel-like roller member adapted to continuously engage a container chime during the opening operation
B67B 7/74 - Roller drive means causes initial piercing, i.e. force applied to rotate the wheel-like member causes the cutting element to pierce the container wall
SPOUT ATTACHMENT SYSTEM ABSTRACT OF THE DISCLOSURE The plastic spout of an electric kettle is secured to the periphery of a spout aperture in the body of the kettle by way of a retainer ring contained within the spout aperture crimped in clamping engagement with an inturned flange of the spout located in overlying relation with a portion of the periphery of the spout aperture. The plastic spout inturned flange is provided with one or more ribs on the face thereof abutting the periphery of the kettle spout aperture, to effect sealing therewith under the compressive load provided by the crimped ring portion. The retainer ring may comprise a separate crimp ring or a flange portion drawn out from the kettle blank.
