Abstract
851,401. Drilling-machine details. PROGRESS DRILLING MACHINE WORKS Ltd., FRYE, J., and SELBY, J. Jan. 9, 1957 [Oct. 11, 1955], No. 28913/55. Class 83 (3). in a drilling-machine, a vertical spindle 10 has an upper portion 11 with tooth-shaped splines which engage pulley 12 and also slidably engage a gear 14 so as to feed a quill 24, through a gear 16, worm 18, worm-wheel 19, pinion 21 and a rack 22 on the quill. The worm 18 is on a shaft 17 which is rockable about a spindle 23 and is mounted in a bearing-bracket 26. The latter is movable manually by a handle 36, or mechanically by a latch assembly, so as. to disengage the worm 18 from the worm-wheel 19. The latch assembly comprises a horizontal pin 27 on the bracket 26 which passes through a hole in a fixed vertical plate 28, a second fixed vertical plate 29 having a hole in line with the pin 27, and a latch 30, pivoted at 31, which moves between the plates 28, 29 to prevent the pin 27 passing into the plate 29 when the worm and wheel 18, 19, are in mesh. A screwed rod 33 is attached at 32 to the quill 24 and has adjustable nuts 34 thereon which, at the end of a drilling-operation, engage latch 30 to depress it and allow a spring 35 to swing the shaft 17 aside and disengage worm 18 from worm-wheel 19, the pin 27 being free to pass into the plate 29. To return the drill-spindle, its drive is reversed and the shaft 17 is swung manually to the position of Fig. 4, whereupon the spindle and rod 33 are raised and latch 30 returns to lock the worm 18 in engaged position, by pin 27. On reaching its uppermost position, a dog 37, Fig. 2, on plate 32 engages latch 30 to disengage worm 18. To start another feed, the worm is engaged by handle 36 and is locked as soon as dog 37 releases the latch 30. The quill may be raised and lowered by a handle 38 when worm 18 is disengaged. Preferably the gear 14 and a bush 13 in the pulley 12, forming the splined connection with spindle 11, are formed of synthetic resin, such as nylon.
