Spoke-siz′ing ma-chine′.
(Wheelwrighting.) A machine for planing the sides of spokes and bringing them to a uniform shape; the edge of the tenon may be tapered at the same operation if desired. The spoke is placed upon the table c, where it is held against a stop, adjustable to different sized spokes; the table is pushed forward to an amount determined by the previous adjustment of a collar on the stop, bringing the side on the spoke in contact with the cutters on the rapidly rotating cutter-head b, which at once dress that side of the spoke and tenon; it is then turned over, and the other side similarly dressed. On drawing the spoke forward and releasing it from the stop, the desired bevel is given to the edge of the tenon by means of the cutters, the particular inclination being determined by an adjustable angle-gage.
