An anchor assembly is disclosed for suspending objects to a concrete structure. The assembly includes an anchor housing having a jaw assembly therein and a opening for receiving an anchor member such as a threaded rod. The jaw assembly includes threaded rods having a threaded opening, a wood form anchor assembly and a metal decking anchor assembly. The wood form and the metal decking anchor assemblies may accommodate the anchor housing and the anchor housing is used in one of the wood form anchor assembly and the metal decking anchor assembly. The metal decking anchor assembly includes a nose-piece and the anchor housing is selectively connectable to the nose-piece via a locking connection such as a bayonet connection.

Cast-in place anchor with lockable jaw assembly

A power tool is provided including a housing defining a cavity therein, where the housing includes a motor case and a handle portion extending along a longitudinal axis of the housing from the motor case; an electric motor having a drive shaft and mounted within the motor case; a partitioning wall extending radially and separating the motor case portion from the non-motor case portion of the housing; and a bearing pocket with an open end facing the motor case portion formed in the partitioning wall and a main body extending away from the electric motor for receiving a rotor bearing. The handle portion includes two elongate walls extending from the partitioning wall, a circuit board supported by the two elongate walls and including a motor drive circuit, and two covers secured to the two elongate walls to cover the circuit board.

Handheld power tool with brushless electric motor

A power tool is provided including a motor case and a handle portion. An electric motor having a drive shaft is mounted within the motor case. A circuit board is disposed in the handle portion to accommodate a motor drive circuit. The motor drive circuit includes a rectifier configured to receive an alternating current from an alternating current (AC) power source and convert it to a direct current supplied to a DC power bus, and a bridge circuit having motor switches connected between the rectifier and the electric motor. A bus capacitor is mounted on the circuit board and coupled across the DC power bus. An auxiliary capacitor having higher capacitance than the bus capacitor is switchably coupled across the DC power bus. The handle portion includes a support member protruding radially outwardly to accommodate the auxiliary capacitor.

Handheld grinder with brushless electric motor

A power tool is provided including a housing, a motor disposed within the housing, an on/off switch having a contact tip disposed within the housing for activating the motor, a paddle switch coupled to the housing via a pivot member and having a paddle trigger engageable by a user, a switch contact lever disposed in selectable engagement with the contact tip of the on/off switch to activate or deactivate the on/off switch, and a biasing member disposed between the switch contact lever and the paddle switch to absorb a travel distance of the paddle trigger with respect to the switch contact lever.

Paddle switch

A power tool is provided including a motor driving a shaft and a drive spindle. The drive spindle includes an outer spindle rotatably driven by the shaft and an inner spindle disposed within the outer spindle. The outer spindle includes an end portion defining an engagement surface for mounting a working accessory, and the inner spindle is axially moveable along a longitudinal axis of the outer spindle but rotationally fixed to the outer spindle. A spring member is arranged to apply a biasing force on the inner spindle in a first direction with respect to the outer spindle. Securing the working accessory on the drive spindle against the engagement surface of the outer spindle applies an axial force on the inner spindle in a second direction opposite the first direction with respect to the outer spindle.

Accessory clamp and spindle lock mechanism for power tool

A handheld grinder includes an elongated housing, an electric motor, an output shaft, a wall, a planar circuit board, and a motor drive circuit. The elongated housing defines a cavity therein and includes a motor case disposed at a front end and a handle portion to a rear end. The electric motor has a drive shaft that is mounted within the motor case. The output shaft is drivably coupled to the drive shaft of the electric motor. The wall separates the cavity between the motor case and the handle portion of the housing. The planar circuit board disposed in the handle portion of the housing. The motor drive circuit is accommodated entirely within the handle portion of the housing on the planar circuit board.

Power tool with separate motor case compartment

A power tool is provided including an elongated housing. The housing includes a motor case disposed at a front end thereof and a handle portion extending along a longitudinal axis of the housing from the motor case to a rear end of the housing. The handle portion includes two elongated walls extending from the motor case along the longitudinal axis of the housing to form a planar opening within the handle portion. A partition wall is arranged along an axis substantially perpendicular to the longitudinal axis of the housing, separating the handle portion from the motor case. An electric motor having a drive shaft is mounted within the motor case, and a module casing supporting a planar circuit board is received within the planar opening and supported by the elongated walls within the handle portion of the housing axially along the longitudinal axis of the housing.
