Abstract

225,961. Bradley, T., and Bradley, E. J. Sept. 22, 1923. Drilling-machines. - A drilling-machine has combined with it a grinding-wheel rotated directly from the driving spindle and serving as a flywheel. The drill-spindle 7 is carried by a head 4 vertically adjustable on a pillar 3 and is rotated by a splined bevel-pinion 32 and a bevel-gear 31 driven by a hand-wheel 28 or by a belt or chain. The bevel 31 carries a spur wheel 30 engaging a pinion 35 connected by a spindle 36 to a grinding- wheel 43 clamped by a nut 45 between a washer 44 and a collar 40 on the spindle. An L-shaped rest 55 is clamped by a screw 52 and two perpendicular slots to a plate 39 on the drill-head. Feed is imparted to the drill-spindle by an eccentric on the driving-spindle 27 engaging a lever 57 pivoted to the head at 58 and carrying a pawl 24 coacting with a ratchet 20 splined to a screwed sleeve 14 on the drill-spindle, the lever being maintained in contact with the eccentric by a spring. A hand-wheel 15 secured to the sleeve serves to withdraw the drill and a ball-bearing 17 is inserted between the sleeve and spindle. In a modification, the spur-wheel 30 may be separate from the bevel-gear 31 and disposed outside the head 4 or it may be replaced by a sprocket-wheel and chain.
