Abstract
Abstract A shaper spindle and cutter are received in bearings in a hollow retaining quill and this assembly of parts is mounted for vertical adjustment in a shaper housing having a split cylindrical body suspended from the underside of an upright work table member. A special pulley housing attached at the lower end of the shaper housing contains a drive pulley isolated in vertically spaced bearings. The pulley is formed with a vertical spindle aperture in which is fixed a female spline drive element and within which is slidably supported a male spindle spline section. Stationary power driving means in the table member carries a pulley belt which engages around the drive pulley in constant alignment and with radial load imposed by the tension of the belt being effectively taken up by the vertically spaced bearings without transfer of any appreciable part of the load to the spindle.
