22,563. Wadkin, J. W., and Jarvis, D. J., [trading as Wadkin & Co.]. Oct. 19. Sawing boring and drilling. -In a rotary-cutter woodworking machine of the type described in Specification No. 25,351, A.D. 1904, in which the cutter spindle and worktable are adjustable in any direction, the spindle head 34 has a barrel which is revolubly mounted in a sleeve in a radial arm 1 and is fixed, laterally by a plate engaging the end of the sleeve, and radially by a setscrew bearing on a block forced down on the barrel. To hold the head at any desired angle, it is provided with a spring- controlled index-pin 39, which engages holes 38, Fig. 4, on a semicircular plate 1<c> on which is fixed an index 37. To prevent the cutter spindle 40 from getting out of truth, the pin passes through a block 59, Fig. 7, adjusted round the projection 34<d> by set screws 60. The arm 1, which rocks on trunnions 2 in the framing, is counterbalanced by a hollow rear part 41, Fig. 2, and is held in a deadhorizontal position by a spring- controlled pin 6, which may be held in or out of a hole in an arc-piece 16, fixed to or formed on the machine framing by a rod 7 connected to a lever 8 held in its disengaged position by a catch 9. The arm 1 may be secured at any desired inclination by the engagement with the arc-piece of a pivoted cam 14, which is jointed to a rod 11 screwed through the bracket 12 or by a screw alone. The arm 1 may also have a positive amount of self-locking radial movement imparted to it. On the rear end of a rod 18 is fixed a bevel-wheel 20, which gears with the teeth of a quadrant 21, Fig. 14, carried on the part 4 of the rocking arm. The quadrant is slotted to receive a block 23 which is adjusted by a screw 25 so as to move the pin 24 a desired distance from the fulcrum 21<a>, the pin being locked by a rod 27 which is clamped in the jaw of an arm 29, pivoted to the frame at the point 30. This arrangement is employed when the cutter spindle is horizontal. When it is desired to lower the spindle head a less distance than the stroke to which it is set, a disc 31 is provided, having an index 32 and stops 33 which are adjusted round the face of the disc and are engaged by the spring catch 19<a> on the lever 19. The cutter spindle 40, which is surrounded by a tapered sleeve, itself surrounded at each end by sleeves located in bushes in the ball bearings 1<d>, is moved relatively to the head 34, either with a quick positive or a slow self-locking movement. The former movement is effected by a crank 41, Fig. 10, provided with an index 53 for setting a crank-pin 43 which is received in a block adjusted in the slot 41 by a screw. The crank spindle 42 passes through a quadrant bracket 47, and the crank-pin 43 engages a die-block moving at rightangles to the spindle 40 in a slide 34<c>. The handlever 50 carries a spring pin 49 which enters holes 51 in a quadrant 52. To obtain the slow movement of the spindle, it is connected by a crosshead to two rods 54, 55 which pass through guides 47<a>, 56, the latter rod of which is screwed through a boss on the quadrant bracket 47. The spindle 40 is driven in either direction by a belt which passes round a pulley 40<a> keyed to it, over guide-pulleys 65, Fig. 2, and round a pulley 61, on the shaft of which are mounted two loose pulleys driven in opposite directions, the belts on which may be moved on to a fixed pulley by ordinary striking- gear. The spindle may be driven directly by a motor, which may be reversed for driving the spindle in either direction. The universal-movement work-supporting table A moves laterally on runners on a foundation frame, to which it may be locked by a wedge 68 adjusted by a screw.
