ABSTRACT:
A multi-purpose power tool in which a power head and a power carriage are mounted for reciprocal translation on a pair of elongated tubular ways, the ways being pivotally mounted and counterbalanced with respect to a generally horizontal base or stand such that the power head and carriage may be moved independently in a horizontal plane or, alternatively, in a vertical plane. The power head and carriage assemblies may be moved in a precise manner relative to the ways, either manually or by means of a variable speed motor drive. Included within the power head is an arbor assembly which passes through a quill member, the arbor also being driven by a variable speed motor. The quill assembly is provided with means for moving same outwardly from the power head to a desired extent and for subsequently locking it in that position. The carriage assembly includes means for supporting and accurately positioning a work holding table. By properly choosing the tool elements to be mounted on the arbor, the multi-purpose power tool can be made to function as a table saw, a disc sander, a vertical drill press, a lathe, a horizontal boring machine, a horizontal or vertical milling machine, a stationary adjustable router or a high speed shaper.
