Abstract

1354435 Drilling and dowel inserting machine JAMES BUCHANAN & CO Ltd 14 Feb 1973 [21 Feb 1972] 7935/72 Heading B3C [Also in Division F2] A machine for boring a dowel hole in a workpiece 2 and for inserting a dowel into the hole comprises a table 15 carrying a power drill 17 and a dowel inserting device 16 which has a plunger 21 and means for guiding the plunger to push a dowel along a dowel insertion axis, the table being movable between a drilling position and a dowel inserting position in which the dowel insertion axis is aligned with the line on which the axis of the drill lies when the table is in the drilling position, a support 1 for a workpiece, means for holding a workpiece fixed in position on the support so that a surface of the workpiece frees the drill when the table is in the drilling position, means for advancing the drill along its axis when a dowel hole is to be drilled and means for advancing the plunger along the dowel insertion axis when a dowel is to be inserted. The dowel inserting device has a breech block 18 with a breech 18a aligned with a muzzle 19. An escapement block 26 closes the breech 18a so that chamber 26a communicates therewith. Dowels are fed through a tube 27 and pulses of air from cylinder 29 ensure that a dowel is moved from the escapement chamber into the breech. Movement of slide 15 is controlled by ram 31 with stops 37, 38 on screw 35 limiting the travel. Drills 44, 45, 46 can be operated in conjunction with drill 17 as required. A workpiece is clamped against fence 4 by bar 11 operated by pneumatic cylinders 9, 10. The machine can be operated semi-automatically through appropriate valves and switches.
