Abstract
Apparatus for woodworking including boring, mortising, tenoning, forming dovetails, duplicating a three dimensional object, and the like. The invention embodies means for providing movement of a workpiece in a horizontal plane or X-Y direction, and means for providing vertical cutting tool movement.
Claims12
A machine tool for use in reproducing a three-dimensional object comprising in combination:
- (a) a drive motor, a router bit and a belt drive housing assembly pivotally mounted on a base for motion in a vertical plane,
- (b) a work carrying platform supported for motion in a horizontal plane mounted on said base, and
- (c) means for effecting simultaneous motion of said assembly and said platform by an operator.
A power tool having a drive motor, a rotatable cutting tool holder, belt means to rotatably connect the motor to the tool holder and a housing to cover the belt means and support the tool holder comprising in combination:
- (a) a base
- (b) a frame slidably mounted on said base for motion in a first horizontal plane,
- (c) a platform slidably mounted on said frame for motion at a right angle to said frame in a second horizontal plane,
- (d) means to support said motor and housing at one end thereof for motion in a vertical plane,
- (e) a bracket secured to said platform and moveable therewith,
- (f) means to secure a three dimensional object to one side of said bracket,
- (g) means on the other side of said bracket to secure a work piece to the platform,
- (h) first arm connected at one end to said motor supporting means,
- (i) a second arm pivotally connected to the other end of said first arm,
- (j) a third arm pivotally connected between the said second arm and the said housing, said first, second, third arms and said housing forming a parallelogram,
- (k) a tracing element secured to said second arm, and,
- (l) a vertical rod interconnecting between said base and said platform.
A machine tool for use in reproducing a three-dimensional object comprising in combination:
- (a) a base,
- (b) a frame sidably mounted on said base for motion in a first horizontal plane,
- (c) a platform sidably mounted on said frame for motion at a right angle to said frame in a second horizontal plane,
- (d) a series wound motor having a router bit secured to its output shaft,
- (e) means to support said motor for motion in a vertical plane,
- (f) a bracket secured to said platform having means to secure a three-dimensional object to one side thereof and means on the other side to secure a workpiece to said platform,
- (g) a first arm connected at one end to said motor supporting means,
- (h) a second arm pivotally connected to the other end of said first arm,
- (i) a third arm pivotally connected between the said second arm and the said motor supporting means, said first, second, third arms and said motor supporting means forming a parallelogram, and,
- (j) a tracing element secured to said second arm in the same vertical plane as the said router bit.
