US 2010/0108194 A1 · WOOD WORKING MACHINE

Abstract

A wood working machine is described that includes a mounting plate assembly for supporting a cutting tool, the mounting plate assembly including a base plate, first and second spaced apart intermediate plates on the base plate, and first and second guide plate elements pivotally supported on respective first and second intermediate plates, and a cutting tool support plate slidably disposed between the first and second guide plate elements, the guide plate elements including means defined therein for positioning each of the guide plate elements at selected angular intervals with respect to the respective first and second intermediate plates, whereby the cutting tool support plate is slidably movable on the base plate between the guide plate elements at a prescribed angle. The mounting plate assembly may include laser sources providing crossed laser beams for accurately positioning the tool bit of the cutting tool near a work piece, and light sources for illuminating the tool bit. A digital sensor may be included for precise positioning of the work piece held beneath the base plate on a movable carrier. Work holding fixtures such as a mortising plate or multiangle work holder may be optionally attached to the moveable carrier to hold the work piece in alternative ways.

Dependent claims

A woodworking machine, comprising:

(a) a support;
(b) a movable carrier on said support;
(c) a mounting plate assembly attachable to said support for supporting a cutting tool, said mounting plate assembly including a base plate having means for attachment to said support, and including first and second intermediate plates on said base plate and defining a space therebetween, and including first and second guide plate elements pivotally supported on respective first and second intermediate plates, and including a cutting tool support plate slidably disposed between said first and second guide plate elements, said guide plate elements including means defined therein for positioning each of said guide plate elements in fractional degree increments with respect to respective said first and second intermediate plates, whereby said cutting tool support plate is slidably movable on said base plate between said guide plate elements at a prescribed angle relative to said movable carrier;
and
(d) a mortising plate attachable to said movable carrier beneath said mounting plate assembly, said mortising plate having a slotted surface for supporting a work piece thereon.
