Definitions

  • This invention relates'to multiple rotary cutter wood slotting machines of the kind wherein the cutters are movable longitudinally of the wood stock to form longitudinal slots therein.
  • the object of the present invention is to provide, in such machines, means for coupling a number of cutters together for simultaneous longitudinal movement by hand, the total amplitude of movement by each cutter being variable within limits and variable with respect to the amplitude of movement of each of the other cutters.
  • such means comprise a plate, provided with a series of parallel guides, pivoted to a fixed part of the slotting machine and rotatable about an axis lying in a plane'parallel to that ofthe wood stock and at right-angles to the longitudinal axis of the slots to be cut, the guides of the plate being at rightangles to the axis of rotation of the plate, anchor members engaged one with each guide of the plate andadjustable and se'curable in a desired position along the length of the respective guide so as to permit variation of the length of arc traversed by each anchor ,member as the plate is rotated, and connection links coupled one between each anchor member and one of. the cutters, whereby when the plate is moved through a portion ofa revolution the respective cutters. are moved longitudinally of the wood stock for a distance determined by the relative positioning.
  • FIG. 4 Figured shows the guideplate seeninifront view; Fig. 2 shows the guide plate in side elevation; Figs. 3 and 4 are respectively a schematic side elevation and a schematic plan view of a cutter to which an embodiment of the invention is applied; Fig. 5 illustrates diagrammatically the principle of operation of the apparatus.
  • the movable plate I ( Figure 1) is constituted by a preferably metallic member of rectangular shape in which are provided grooves or slideways such as Z, 3, 4.
  • Control rods I I are each coupled to the plate by an articulated link arm I2, ball and socket joints I3 and I A, and an anchor bolt I5 constituted by a head IS, a threaded portion I! and a locking nut II*.
  • the plate I is mounted on the frame I8 of the'machineby'means of the shafts itand'st'ops 19' limitthe amplitude of movement'of rotation of the plate to 180.
  • the upper part 29 of the slotting machine comprises guiding rails 2
  • the motors 29 are secured in position on'the carriage supports 22 by conventionaltightening'means (not shown).
  • control rods I I are supported by the bearings 25 and Zfibf the frame I8 and pass through the carriage supports 22 of the motors. Keying means 2?, 28 permit'to couple the rods II to the corresponding carriage supports 22.
  • Each cutter assembly comprises a motor 29 and the slotting cutter 3B, or 3
  • the machine comprises a number of cutters corresponding to the number of slots to be made on the piece'32 to be worked.
  • the carriage supports 22, movable in the direction of the arrows A, B on the rails 2 I, are bored to receive the parallel rods I I.
  • the motors 29 for driving the slotting cutters are movable in the direction of the arrows C,'D.
  • the left-hand extremities of the rods (in Figs. 2, 3, 4 and 5) are each coupled to the plate in the manner described with reference to Fig. -2.
  • the workpiece would conveniently be fixed on a table (not shown) which would be arranged to slid'ef vertically by known means. j If the cutter 30 h s to effect a slot of two centimeters length and the cutter 3! a slot of four centimeters length, the rod 2:! is fixed to one carriage support 22 (Fig. 4) and the rod 23 to the other carriage support by the keying means 2! and 28.
  • each rod is then positioned at the appropriate graduations '5 and 6 and the plate (Fig. 5) is thereafter rotated through to eifect longitudinal movement of the cutters.
  • the cutter coupled to the rod 23 will be displaced by a similar amplitude I, J, whilst the cutter coupled to the rod 2 5 will effect a simultaneous movement of an amplitude K, L equal to that of G, H.
  • the positioning of the slots in the direction transverse to their length is obtained by transverse displacement of the cutter motors on their carriage supports.
  • the plate comprises as many slots as the machine has cutters.
  • means for coupling a number of cutters together for simultaneous longitudinal movement, by hand, the total amplitude of movement by each cutter being variable within limits and variable with respect to the amplitude of movement of each of the other cutters, comprising a plate provided with a series of parallel guides, pivoted to a fixed part of the slotting machine and rotatable about an axis lying in a plane parallel to that of the wood stock and at right angles to the longitudinal axis of the slots to be cut, the guides of the plate being at right angles to the axis of rotation of the plate, anchor members engaged one with each guide of the plate and adjustabl and securable in a desired position along the length of the respective guide so as to permit variation of the length of are traversed by each anchor member as the plate is rotated, and connection links coupled one between each anchor member and one of the cutters, whereby when the plate is moved a through
