Abstract

465,207. Drilling. ASQUITH, Ltd., W., and JOHNSON, A. Nov. 9, 1935, No. 31013. [Class 83 (iii)] A radial or other vertical drilling- machine is provided with a balance and trip motion drum, carrying an adjustable stop for co-operating with a fixed stop or trip, which is rotated by gearing from a rack pinion shaft, the gearing being arranged so that the drum makes less than one revolution for the full length of the spindle travel The shaft A, Fig. 3, for moving the spindle B through rack-and-pinion gearing carries a further pinion C meshing with the toothed periphery D of a drum d. The drum houses a coiled flat spring d<2> which may be tensioned as desired to balance the spindle and its attendant parts ; the outer face of the drum is provided with T-slot G in which an adjustable stop H is positioned according to the depth of feed required and shown by graduations f, Fig. 2. The stop H may trip the automatic feed lever J or may engage a dead stop where only a hand feed is provided.
