Abstract
A tool for cutting a predetermined molding pattern into a work piece as it is longitudinally advanced. A molding head is adapted to be mounted to the output shaft of a motor. The head is generally-circular and includes at least one arcuate cutout in its peripheral edge for receiving a generally-circular cutter unit. The arcuate cutout is greater than semicircular so that the center of the unit lies within the peripheral edge and is therby protected from radial travel. A bayonet-type fixture and an alognment screw are provided for engaging the cutter unit to the molding head whereby multiple devices protect the operator from violent disengagement of the cutter unit from the head during high speed cutting.
Claims2
Apparatus for cutting a predetermined profile into a work piece comprising, in combination:
- a) a generally-circular planar molding head;
- b) at least one generally-circular planar cutter unit;
- c) said head having at least one arcuate aperture adjacent its periphery adapted to receive a cutter unit;
- d) means for fixing a cutter unit within said aperture, said means including (i) a pin fixed to said molding head and extending into the interior of said arcuate aperture and (ii) a slot within a peripheral edge of a cutter unit located to coact with said pin;
- e) said slot including a horizontal slot portion and a vertical slot portion, said vertical slot portion being internal to the periphery of a cutter unit;
- f) the opposed ends of said horizontal slot portion intersecting a planar surface of a cutter unit and the top of said vertical slot portion;
- and
- g) said arcuate aperture for receiving a generally-circular planar cutting unit being greater than 180 degrees whereby the center of a generally-circular cutter unit lies within the periphery of said head.
