Definitions

  • the present invention relates to a method and means for joining parts together in a simple, cheap, and efiective manner, so that assembly and dismantling are facilitated.
  • Figure 1 shows a general view in elevation of the movement.
  • Figure 3 shows a view from the direction of arrow III in Figures 1 and 2.
  • This comprises an electric motor 1, having a stator with two sets of interdigitated poles lying in a circle, this being mounted upon a sheet-metal member 2 in the general form of a shallow U.
  • the spindle 10, of the motor extends through the base of the member 2, in the direction of the arms.
  • Each arm of the member 2 is formed with a pair of metal lugs, as indicated at 3, one on either side thereof ( Figure 4), extending in the plane of the arm and at right angles to the direction of the motor spindle.
  • the end of each'lug 3 is parallel to the side of the arm, and a slot 4 extends part-way through each lug, adjacent its end, making an acute angle of, preferably, about 30 with the end of the lug.
  • the lugs each extend through a slot 5 formed in one of two plates, 7, 8, of synthetic resinous fabric based material, conveniently of the kind known under the trademark Tufnol.
  • the plates are rigidly located with respect to each other and to the member 2 by twisting the end portion of each lug so that the sloping edge of each end portion engages with one side of the associated slot 5.
  • Plates 7, 8 are further located relative to each other by means of a pair of pillars 9 attached to each plate adjacent to the side away from the slots 5.
  • Electric terminals 21, 22, are mounted on plate 7, and are connected through leads 23, 24 to the ends of the motor winding.
  • Plate 7 is formed with a slot 25, through which a twin insulated electric flex 26, may be passed to anchor it, the ends of the flex leads being connected to terminals 21, 22.
  • a method as claimed in claim 1, comprising also the step of forming the second part with a shoulder to engage with the first part on the side away from the end portion of the tongue.
