摘要： A line generator includes a housing carrying a light source for emitting a light beam and a mounting surface for removably mounting the generator on a surface. The line generator includes a gravity dial having at least one indicator, wherein when the mounting surface is substantially vertical, the gravity dial will self level under the influence of gravity and the at least one indicator will indicate whether the emitted light beam is in a predetermined orientation selected from one of a vertical line or a horizontal line.

摘要： A self-leveling line generator may be removably disposable on a surface. The line generator includes a housing carrying a light source for emitting a light beam and a lens holder for carrying a lens that converts the light beam to a planar beam. The lens holder is movable with respect to the light source housing and is self-leveling so that the planar beam is in a fixed orientation on the surface on which the planar beam contacts.

摘要： A modular tool assembly including a tool base configured to releasably secure a modular tool arrangement in a fixed relationship relative to a mounting surface. The tool base includes an upper housing portion and a lower housing portion having a mounting seal extending therefrom. The mounting seal cooperates with the mounting surface to define a vacuum pocket therebetween. A vacuum generating mechanism is configured to remove air from the vacuum pocket through an aperture in the lower housing portion. A modular tool attachment releasably engages a portion of the tool base to secure the modular tool attachment to the tool base. The modular tool attachment can include a self leveling laser leveling device having a laser light source mounted within a housing to project an alignment beam through an opening in the housing to denote a reference plane along the mounting surface.

摘要： An adjustable handle assembly is provided for use with a hand-held power tool, such as a polisher, to enhance control while operating on delicate surfaces of varying contours. The handle assembly includes a handle mounted to the housing of the tool in a manner that facilitates quick adjustment of the handle between various predetermined positions relative to the housing without the use of tools, turning of nuts and bolts and prolonged work stoppage. The handle assembly also includes lock members on one of the handle and the housing and lock receiving grooves on the other of the handle and housing which can cooperate with the lock members to fix the handle in one of the predetermined positions relative to the housing. For quick adjustment, the handle assembly includes a lock manually movable by a user between a locking position in which the lock members are urged into the grooves to lock the handle relative to the housing and a release position in which the lock members are free to move from the grooves, thereby allowing the handle to be adjusted relative to the housing between the predetermined positions. The handle assembly also includes a cam means located between the lock and the handle to urge the lock members into the locking position with the grooves. The cam means may include cooperating cam surfaces on the lock and the handle.

摘要： An electrically-powered polisher is provided which includes a central housing having a top and a bottom and a front and a back with a rotary pad mounted adjacent to the bottom of the housing. A front handle extends horizontally outwardly from the housing front substantially parallel to the top and bottom of the housing adjacent to and above the housing bottom. A rear handle extends outward from the housing rear and extends vertically between the top and bottom of the housing. A collar is defined at the top of the housing and a male receptacle, including male prongs, is mounted therein. The male receptacle is capable of being electrically connected to a female socket head of an electrical cord supplying power to the waxer. The collar is recessed in the top of the housing with the male prongs of the receptacle extending from the housing into the collar. A cord lock is provided and includes a cord receiving trough formed in the top of the housing adjacent to the collar and an overhung tab for retaining a portion of an electrical cord in the trough.

摘要： A 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 having a plurality of tabs extending axially outward from a top surface and radially outward from a central axis is mounted for threaded rotation on a bolt passing through the projections radially with respect to the router motor housing which bears against the camming surfaces so as to squeeze the ring in order to effect a clamping action as the knob is moved inwardly.

摘要： 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. Rotational engagement of the ring with the base is effected by providing an annular groove on the base and a projection on the ring engaging the groove. The projection is formed with a plurality of pockets each having an opening communicating with the groove. Within each of the pockets is a ball which extends through the opening to contact a wall of the groove and thereby act as a ball bearing.
