Definitions

  • the present invention relates to double-twist spindles and more particularly to a means for decreasing the wear of threads to be twisted as they pass through the double twist spindle.
  • One of the objects of the present invention is to construct' a double twist spmdie in such a way that it produces a minimum of wear and damage on the threads to be twisted as they pass through the double-twist spindle.
  • Another object of the present invention is to provide a double-twist spindle of the above type which consists of very few and simple parts for reducing the wear of the thread to be twisted.
  • a further object of the present invention is to provide a double-twist spindle of the above type in which the parts may be very easily assembled, disassembled and exchanged as required.
  • the present invention mainly consists of a double twist spindle having a pair of spindle core members which are spaced from each other and supported in a slotted tubular member.
  • One of the core members is bored along its axis, and the other of the core members. is formed with a cutout aligned with a slot of the tubular supporting member.
  • a ringshaped guide member provided with a central aperture aligned with the bore of the one spindle core member and overlapping the cut-out of the other spindle core member, so that the thread to be twisted may pass through the bore of the one spindle core member, through the aperture of the ring-shaped guide member, through the cut-out of the other spindle core member and out through the slot in the tubular support member.
  • This ring-shaped core member is made of a hard material such as steel, which may be chrome plated, ceramics, or porcelain, and the aperture of the ringshaped core member is curved and provided with a smooth surface so as to produce a minimum of wear on the thread passing therethrough.
  • the ring-shaped guide member is preferably of a lesser thickness than the space between, the two spindle core members.
  • Fig. l is a partial sectional, view of one possible construction for carrying out the present invention
  • Fig. 2 is an end view of a lower spindle core member and shows the top end face thereof
  • Fig. 3 is a fragmentary sectional view taken along line 3-3 of Fig. 2 in the direction of the arrows.
  • a spindle'core member 1 which is bored along its axis at 5 and a spindle core member 2 which is provided with two or more sector-shaped cutouts 2a in the end portion thereof located adjacent.
  • the spindle core members 1 and 2 are slightly spaced from each other and fixedly mounted in tubular member 3 so as to be supported thereby.
  • the tubular. member 3. is provided with two or'more slots 7 which are aligned with the cutouts 2a in the upper end poruon or the spindle core member 2.
  • the ring-shaped member 6v which may be made of steel, which may be. chrome plated, or of a ceramic material. or of porcelain.
  • This ring-shaped member 6 has a central aperture aligned with the bore 5 and overlapping the cutouts 2a or the spindle. core member 2. of the aperture of the ring-shaped member 6 which is adjacent to core member 1 is smaller than the. end thereof which is located adjacent to the core member 2, and that this aperture is smoothly curved between the ends thereof.
  • the ring-shapedv core. member 6v is provided with a hard, smooth surface at least at. the aperture thereof and is of a slightly smaller thickness than the space between the core members I. and 2 so.
  • the tubular support member 3 is mounted on the. member 8 which has two or more cut away portions 8a aligned with the slots located between parts 8b and 8c of member 8,.
  • the dish-shaped member 9 which has a hollow central projection in which the ball bearing 11 and the roller bearing 10 are mounted, as shown in the drawing. These bearings interconnect the dish-shaped member 9 with the spindle core member I, and the ball bearing 11 is tubular support member 3.
  • the dish-shaped member 9 is intended to remain substantially stationary and, to support the spool of thread to be twisted on the central projection thereof, while the parts 1, 2 6, and 8 all to,- tate together.
  • the thread 4, from a spool (not shown) mounted on the central projection of dish-shaped member 9, passes through the bore 5 of spindle core membet I, through the central aperture of ring-shaped member 6, through a cutout 2a of spindle core member 2, through a slot 7 of tubular member 3, and through one of the cut away portions 8a of the member 8.
  • This latter path for the thread to be twisted forms a conduit means for the thread, and the smoothly curved aperture of ring-shaped member 6 provides a smooth surface at the sharp bend in the conduit means so that a minimum of wear is caused on the thread to be twisted.
  • the thread In other known devices of this type, the thread must pass over a relatively sharp corner' at the bend in the path through which. it moves, and this sharp corner causes damage and wear on the thread to be twisted.
