Abstract

379,999. Lathes. WINKLE BRœDER, Altenstadt-on-Iller, Germany. March 15, 1932, No. 7680. Convention date, March 16, 1931. [Class 83 (iii).] In a copying-lathe for producing articles such as shoe-lasts, rifle-stocks, pipe-bowls, &c. in materials such as metal, wood, horn, &c. the tracer roller c and rotary cutters d are carried by levers k, l respectively and the stationary driving motors s for the cutters are arranged concentrically with the pivots m of the levers l. As applied to the production of shoe-lasts, right and left hand lasts b are made simultaneously from a pattern a, but one or more work-pieces may be produced simultaneously from one pattern and of the same size or larger or smaller. The pattern and blanks are clamped between spindles e, f on a slide h which is traversed axially during cutting by a screw i. The levers k, l are joined by links n and are influenced towards the work by a spring o, but may be held withdrawn by engaging a notch q on a handle p with a stop r. The motors s are fixed concentrically with the pivots m but independently thereof and drive the cutters through belts t. The feed screw i and lathe spindles are driven from a shaft (not shown) through gears I .. IV and the levers k, l may oscillate in an inverted position. The cutters d are of such a size that they can follow any recesses in the work.
