Geared universal cutting frame with interchangeable spindles

Geared universal cutting frame with interchangeable spindles, for ornamental lathe

This is an appliance for the ornamental lathe by means of which such work as fluting, drilling, etc, may be performed.

A square bar, held in the slide-rest of the lathe, has its end formed as a circular flange with a graduated edge. Upon this flange a frame is mounted capable of being clamped in any position by a bolt passing through the axis of the bar; this frame carries a spindle, with its axis at right angles to that of the bar. The spindle is driven at a high-speed through bevel gearing, pulleys, and a belt, from an overhead gear. Three interchangeable spindles are provided, adapted for carrying fly-cutters, drills, and milling cutters respectively.
