Abstract

24,492. Douglas, G. C., [Ford, W. F.]. Nov. 8. Drilling; reamering.-Relates to a drilling or reamering machine in which the drill is driven through toothed gearing by hand or power, and the feed is effected by a rack and pinion. The drill or reamer is carried by a spindle 6, a pinion on which is driven by a spur-wheel 13 on a spindle 15. A worm-wheel 16 on the spindle 15 is driven by a worm 17 on a spindle 18, carrying two wheels 19, 20. A sleeve 24 on the driving-spindle 21, carrying two toothed wheels 22, 23, can be moved so that the wheel 22 gears with the wheel 19 or the wheel 23 with the wheel 20. The feed is effected by moving the spindle 6 axially by means of a rack and pinion. A pin 27, Fig. 5, formed on the end of the rack 25 is secured in a sleeve 26 by means of a nut 28. The sleeve 26 screws into the end of the spindle 6. The rack 25 is driven by a worm-wheel 29 on a spindle 30, which can be turned by a hand-wheel, or can be moved axially by a lever 35 so that a worm-wheel 32 driven by a suitable worm is secured to the shaft by a clutch 34. The driving-gear is mounted in a frame 10 which can be reversed on the bed-plate 5, so that the machine can be driven from either side.
