Abstract

16,785. Levin, F. July 21. Milling-machines. -A machine for nicking screw-heads in such a manner that a raised part is formed in the nick is constructed with two rotary segmental saw-blades 25, 26, carried on a slide 29. The saw-blades are connected by spur-wheels, one of which is driven by a wheel 27. When the slide 29 is advanced towards the screw S, the saws cut alternately from one side and the other into the screw-head.
