Abstract

25,512. Whitehead, A. Nov. 7. Feed-motions.-In a radial feed apparatus for sawing- machines, the shaft 20, Fig. 2, mounted within the revoluble pillar carrying the radial arm is driven through worm gearing 22, 21 and toothed gearing 25, 23 from a shaft 26 which is rotated by a pulley-driven shaft 31 through change-speed gearing. The change-speed gearing consists of two series of differentlysized pinions 27, 30 mounted on the shafts 26, 31 and intermediate pinions 29, always in gear with the pinions 27, carried by arms 28 pivoted to the shaft 26. The arms 28 are provided with depending fingers 32 riding on the notched periphery of a handoperated drum or a series of notched disks 33. As each notch comes successively below a finger 32, the arm carrying the finger is depressed by a spring 39 and its pinion 29 is brought into engagement with one of the pinions 30, thus causing the shaft 20 to be driven through that train of gearing. The shaft 6, Fig. 3, carrying the feed-rollers engaging the work is driven through bevel-gearing 16, 10 and a clutch member 9. The clutch member engages a key 7 on the shaft and is actuated to engage or disengage with a clutch surface on the bevel-wheel 10 by a pin 11 eccentrically arranged on a handoperated spindle 12.
