Abstract
127,841. Robinson, C. J. May 26, 1917. Shaping by cutting.-In a machine for making propeller blades on the copying principle by means of a rotary cutter-block controlled by a roller or feeler operating on a dummy, the work 28 is traversed and the cutter-block 44 rotated in a direction lengthways of the blade, so that the cutting is performed with the grain of the wood. The cutter, which is preferably flat or straightedged, is carried by a frame 50 pivoted at 51 and connected by an adjustable rod 52 to a frame 53 carrying the feeler 55 working on the dummy 40. The work and dummy are mounted on a rocking shaft 21 carried by a reciprocating table 2. The shaft 21 is rocked by worm gearing 57, 58 actuated by a pawl lever when a roller 64 on the lever mounts an incline 62 at the end of the movement of the table. The shaft may be additionally rocked during the movement of the table by a cam 67 and a sliding device. Instead of being arranged tandem-wise, the work and dummy may be mounted on separate parallel axes.
