Rotary tool

A sharpening attachment for a powered rotary hand tool of the type which has an output shaft with a tool bit holder that extends from a housing is disclosed. The sharpening attachment is mounted on the housing and comprises a body portion with an interior opening through which a sharpening bit held by the tool bit holder can pass, with the sharpening bit being exposed for engaging a surface of a tool. The attachment has a jaw portion attached to the body portion which extends forwardly thereof and also has a support surface for holding the tool member at a predetermined angle relative to the sharpening bit, and an extension attached to the body portion and extending forwardly thereof at least to a point that includes a major portion of the exposed portion of the sharpening bit for the purpose of providing a protective guard.

A rotary power tool having a light source includes a housing, an electric motor provided in the housing and an elongated spindle engaged with and adapted to be rotatably driven by the motor. A rotatable holding assembly is attached to an end of the spindle and extends from a front end of the housing for holding a tool accessory. At least one magnet is adapted to be rotated by the spindle for producing a magnetic field, and a generally tubular sleeve is attached to the front end of the housing. At least one light emitting diode projects from a front end of the sleeve, generally between the inner and the outer surfaces of the sleeve. An inductive coil is also imbedded at least partially in the sleeve generally between the inner and the outer surfaces, proximate the magnet for generating an electric current from the magnetic field. Electrical conductors are also embedded and routed through the sleeve for supplying the electric current from the inductive coil to the light emitting diode.

Cordless electric rotary hand tool

A right angle attachment configured to be attached to a small electrically powered rotary hand tool of the type that is used in woodworking, hobby work and other work. Being small, lightweight, relatively vibration free and quiet in operation, the attachment is easily attached to a hand tool in a very short amount of time without the use of any special tools. The attachment has a flexible input shaft and an output shaft that are oriented at an angular orientation, such as approximately 90 degrees relative to one another so that the flexible shaft compensates for misalignment between the input shaft and the output shaft of the tool. In operation, the attachment is easily attached to the hand tool by merely removing the chuck that is a part of the original hand tool and attaching the chuck to the attachment output shaft, threadably engaging a driver nut on the rotary tool output shaft, engaging a mounting coupling assembly onto a threaded end of the rotary tool case, and fitting the attachment to the hand tool by merely sliding it into engagement and tightening the coupling assembly by hand.

A switch mechanism for an electrical slide switch that has a detenting or clicking action is disclosed. The switch mechanism provides such detenting action in a mechanism that has a switch lever that moves through an arcuate path of movement and provides a uniform resistance to movement through the entire range of movement of the switch lever.
