Definitions

  • This invention relates to a mounting for the rings of a ring rail of spinning and twisting machines. More particularly, this invention relates to a ring holder for mounting rings on a ring rail.
  • a ring directly on a ring rail.
  • the ring has been mounted on a ring rail made from thin steel plate and has been secured in place, for example, by means of screws provided with large heads or by means of plates screwed onto the ring rail and inserted over projecting parts of the'ring above the ring rail or into grooves milled into other parts of the ring.
  • these mountings have required a compact ring profile with additional projections.
  • the exchange or replacement of the rings has been complicated.
  • a ring having a mounting flange and a tapered extension of the ring below the mounting flange has been mounted directly on the ring rail and centered by a screw in the bore of the ring rail. This screw has been disposed to press against the circumference of the ring rail.
  • This screw has been disposed to press against the circumference of the ring rail.
  • a ring holder in which a ring is received within a recess in the holder has been inserted through, while clearing, a ring rail opening from underneath and is fixed on the ring rail by means of a ring screwed on from above.
  • This holder has been constructed, for example, as a slotted holding ring, to act as a clamping device holding the ring in place by spring action.
  • the maintenance of the roundness of the spinning ring has become questionable. Further, such structures with many projections also induce the formation of fly waste and dust accumulations.
  • a holder for spinning and twisting rings that can be centered has been known in which the ring has been adjusted in the ring rail opening after a fastening screw connecting a cover ring above the ring rail and clamping prongs below the ring rail have been loosened.
  • the whole holding device in order to exchange the ring, the whole holding device must be taken ofl.
  • the rigidity of the ring holders in these heretofore holding devices has thus far been insuflicient as the holder has either been too flexible compared to the ring or has exerted a pressure on the ring.
  • the rings mounted in such holders which deviate from a perfect circular shape not only maintain their deviations from the circular shape but also their roundness is further impaired by deformation.
  • the invention provides a ring holder which is adapted for mounting on the ring rail of a spinning or twisting machine with an exactly circular recess at the periphery for receiving a ring in a sliding fit relation. Further, the ring holder is constructed so as to be rigid in comparison to the ring in order to maintain a perfect roundness of the ring.
  • the ring holder is also constructed so as to be centered on and secured to a ring rail in which the ring is maintained in place by suitable removable means.
  • FIG. 1 illustrates a view taken on line I-I of FIG. 2 of a ring mounted within a ring holder of the invention and a ring rail;
  • FIG. 2 illustrates a top view of the ring, ring holder and ring rail of FIG. 1;
  • FIG. 3 illustrates a cross-sectional view of the ring of FIG. 2.
  • a ring 1 having a substantially uniform inside diameter b is provided with a T- shaped top flange 2 as is known and a bottom flange 3 which extends radially outwardly and has a greater outside diameter than the outside diameter of the T-shaped top flange 2.
  • the bottom flange 3 is of a substantially uniform thickness or height 11.
  • a ring holder 4 which has a circular central opening 5 of the same diameter a as the inside diameter b of the ring 1 and a circular recess 11 in the upper surface about the periphery receives the ring 1 within the recess 11 in a sliding fit relation.
  • the recess 11 has an inside diameter equal to the diameter a of the central opening 5 and an outside diameter equal to the outside diameter b of the bottom flange 3 of the ring 1 and a slight clearance for a sliding fit of the ring 1.
  • the recess 11 is also of a depth equal to the height of the bottom flange 3 of the ring 1.
  • the ring holder 4 also has a collar 6 surrounding the opening and a rim 7 which extends outwardly at a right angle from the upper end of the collar 6.
  • the rim 7 is enlarged into two lappets 8 which are disposed symmetrically on opposite sides of the ring holder 4 and which are each provided with holes 10 having countersunk recesses 9.
  • Each lappet 8 is also provided with a recess 12 of generally U-shape which extends from the outer edge of the ring receiving recess 11 to a peripheral upstanding rim 14 of the holder 4.
  • the recesses 12 are each sized to receive a clamping plate 13, preferably a spring plate or a pretensioned plate, and are of a height such that the plates 13 do not project out of the recesses 12.
  • the peripheral rim 14 is also of a height such that the plates 13 and walls of the recesses 12 do not project past the rim 14.
  • the ring 1 is inserted into the ring holder 4 by placing the bottom flange 3 in the circular recess 11. Thereafter, the clamping plates 13 are placed into the recesses 12 of the lappets 8 in overlying relation to the bottom flange 3 of the ring 1. Screws 15 are then inserted through suitable holes in the plates 13 and threaded into the holes 10 of the lappets 8. As the bottom flange 3 is of the same height as the recess 11, the plates 13 rest evenly on the upper surface of the ring flange 3 to securely hold the ring 1 in the recess 11 when the screws 15 are tightened. Upon loosening of the screws 15 and the clamping plates 13, the ring 1 is readily accessible for exchange.
  • the collar 6 of the ring holder 4 is inserted into an opening 17 in the ring rail 16.
  • the ring holder 4 is then connected to the ring rail 16 by passing the screws 15 through aligned holes 18 in the ring rail 16 and threading suitable rounded nuts or threaded plates 19 onto the screws 15.
  • the opening 17 is larger than the outside diameter of the collar 6 of the ring holder 4 and the holes 18 are larger than the screws 15.
  • the ring 1 can be centered with respect to a spindle (not shown) positioned in the center of the opening 17 by laterally shifting the ring holder 4 in the plane of the ring rail after loosening of the screws 15.
  • the ring holder 4 which can be made of a different material than the ring 1, is considerably more rigid than the ring 1. Further, the 'wall 20 of the circular recess 11 is more exactly round than the bottom flange 3 of the ring 1. Thus, insertion of a ring which deviates from a perfectly circular shape into the circular recess 11 causes a slight pressure on the ring so that the roundness of the ring automatically adapts to the roundness of the wall 20'. Perfect roundness of the ring 1 in use is thus achieved.
  • the invention thus provides a ring holder which is ca- 4 pable of mounting a ring in a spinning or twisting machine about a spindle while maintaining a perfect roundness of the ring.
  • the moutning of the ring holder on the ring rail of the machine permits the ring to be centered with respect to the spindle which passes through thering.
  • the ring holder further permits the ring to be replaced in an easy and rapid manner through means of simple manipulative steps without removal of the ring holder.
  • a. ring holder having an opening of a diameter equal to said inside diameter of said ring and a recess having an exactly circular axially extending wall slidably receiving said bottom flange of said ring to maintain the roundness of said ring;
  • said means includes at least a pair of plates mounted symmetrically in said holder in overlying relation to said ring and means for securing said plates in said holder whereby said ring is maintained against removal from said holder.
  • said holder includes a pair of lappets, each said lappet having a recess receiving one of said plates therein, said plates being sized to lie within the plane of sai dlappets.
