Abstract

824,603. Lathe details. KARLGREN, J. H., and KARLGREN, K. H., [trading as BRODERNA KARLGREN]. Feb. 28, 1958, No. 6540/58. Class 83 (3). In a screw thread-cutting machine, the tool 4a is advanced by a handle 11 to cutting-position against a stop 28, the handle 11 being resilient so that it may be flexed rearwardly to engage a latch 17. The thread-cutting tool 4a is mounted in a turret 3 on a slide 2. The handle 11 is part of a lever 6 pivoted to the slidemounting 1 and engaging in an aperture 10 of the slide 2. A spring 22, assisted by a spring 30, urges the handle 11 to a tool-retracting position, determined by an adjustable rubberfaced stop 25. It is stated that the flexing of the handle prevents vibration of the tool during cutting.
