Abstract
461,793. Lathe &c. feed - motions. KOENIGSBERGER, F. June 5, 1936, No. 15745. Convention date, June 24, 1935. [Class 83 (iii)] A stop-feed mechanism, for lathes or like machine-tools, of the kind in which a rotatable feed nut is normally held against rotation by a clutch device which is automatically released by an overload, has a separate displaceable jamming device normally disposed between the periphery of the nut and a resilient stop for holding this device so that it is instantly displaced to a declutching position as soon as the nut is overloaded. The nut b, Fig. 1, which is mounted in roller bearings in brackets p<1> of the machine slide has depressions f<4> in its periphery adapted to be engaged by a ball d carried by a rotatable sleeve c to hold the nut against rotation during feed. The ball d is maintained in engagement with the recesses in the nut by a roller h carried by a spring-pressed plunger e arranged in a part of the slide. Depression of the handle k fastened to the sleeve c, an overload, or the slide encountering a stop in either direction of motion, moves the ball out of its recess and allows the nut to slip, thereby stopping the feed. The feed may be modified or effected when the lead screw is stationary by rotating the nut by hand through gearing..
