Portable woodworking power tool
First Claim
1. A power tool comprising:
- a support;
a spindle;
first means mounting the spindle on the support for angular movement relative thereto through a predetermined arc into any one of a number of operative positions;
means coupled with said spindle mounting means for releasably securing the spindle in any one of said operative positions;
second means coupled with the spindle for mounting the same for axial movement relative to the support;
a drive shaft rotatably coupled to said spindle;
means adjacent to one end of the drive shaft for releasably attaching a tool thereto;
a motor carried by the support, said motor having a drive shaft; and
means interconnecting the motor drive shaft with the shaft of the spindle for rotating the spindle shaft when the spindle is in any one of said operative positions; and
means coupled with the motor for controlling the actuation thereof.

Abstract
A woodworking power tool comprising a base plate having a motor mounted thereon at one end of the base plate. The motor has a motor housing on which a spindle housing is mounted for rotation through an arc of 180°. The spindle housing has a spindle therein and the spindle is adjustably mounted for up and down movement with referene to the bottom flat surface of the base plate. A toggle mechanism is carried by a handle grip on the base plate for adjustably locking the spindle housing in a fixed, rotative position on the motor housing. A shaft is rotatably mounted in the spindle and has a tool-actuated collet for releasably attaching the shank of a cutting tool to the shaft. A drive train connects the drive shaft of the motor with the shaft of the spindle to rotate the cutting tool on the end of the spindle shaft. Adjustment of the height of the spindle relative to the spindle housing permits the cutting tool to be placed above, flush with, or below the plane of the bottom surface of the base plate so that different types of cuts can be made in workpieces.
