Definitions

  • a braking arrangement for a textile spinning or like spindle comprises a stationary spindle mounting assembly, an annulus mounted for relative rotary and axial movement thereon, said annulus carrying cam means which on rotary movement of the annulus co-acts with cam means on the stationary spindle mounting assembly to impart axial movement to the annulus, means for rotating the annulus, an annular braking surface formed on the stationary mounting assembly and spaced axially from the annulus, and an annular member rotating with the spindle blade and located between the annulus and said braking surface, so that rotary and consequent axial movement of the annulus operates to press said annular member against said braking surface.
  • the cam means may be so arranged as to elfect axial movement of the annulus on rotation thereof in either direction. annulus will be moved in the direction of spindle rotation so that the driving torque, being transmitted to the annulus, will help to keep the brake in operation until released by an operative.
  • FIG. 1 is an elevation of a spindle mounted in an assembly incorporating a braking arrangement according to the invention
  • FIG. 2 is an axial section through the assembly on the line 2-2 of FIG. 1.
  • the spindle blade is mounted in a stationary spindle mounting assembly which includes a conventional bolster 11 having a radial shoulder 12.
  • the bolster 11 passes through a hole 13 in a spindle rail or holder 14 and rests thereon through the shoulder 12 and a flange 201 described below, being secured by a nut 15 threaded on the bolster 11 and bearing against the underside of the rail or holder 14 through a washer 16.
  • the spindle blade 10 may be carried in a tubular insert, the head of which is seen at 17 in FIG. 2, supported in the upper pait of the bolster 11.
  • a driving wharle 18 is fixed to the blade 10 and has a skirt-like annular extension 19 extending radially outwardly above and beyond the shoulder 12 of the bolster.
  • the under surface of the cap 21 forms a braking surface and may be provided with a friction brake lining material.
  • the lower end of the casing has an inturned radial flange 201 interposed between the spindle rail or holder 14 and the shoulder 12 of the bolster 11.
  • the a A cylindrical annulus or collar 22 is mountedon the shoulder 12 of the bolster 11, between the wharle extension 19 and the casing flange 201, and is provided with an arm 23 projecting radially through a slot 24 in the casing 20, by which the annulus 22 can be rotated on the shoulder 12; the annulus 22 is also capable of axial movement relative to the shoulder 12.
  • the underside of the annulus or collar 22 is fashioned with a pair of substantially V-shaped female cam faces 25 which in the running position fit over a pair of studs 26 provided on the upper surface of a plate 27.
  • the plate 27 is non-rotatably mounted on the casing flange 201 through a ring of compression springs 28 mounted in the flange 201 and secured to the plate 27.
  • a partrotary movement of the annulus 22 in either direction by means of its arm 23 is effective, through the co-action of the cam faces 25 with the studs 26, to depress the plate 27 against the springs 28 into contact with the flange 201 and to impart an upward axial movement to the annulus 22,causing the latter to lift the superjacent wharle extension 19 and press it into contact with the under surface of the retaining cap 21, whereby it is trapped and braked, bringing the spindle blade 10 to a standstill.
  • a braking arrangement for a textile spinning or like spindle comprising a rotary spindle, a stationary spindle mounting assembly, an annulus mounted for relative rotary and axial movement on said stationary mounting assembly, first cam means on said annulus, a non-rotating plate member mounted for axial movement on said stationary mounting assembly, compression springs acting between said plate member and said stationary mounting assembly, second cam means on said plate member on its side remote from said compression springs, said first and second cam means co-acting so that rotary movement of the annulus imparts axial movement in opposite directions to said annulus and to said plate member and compresses said springs, means for rotating said annulus, an annular braking surface formed on said stationary mounting assembly and spaced axially from the annulus, and an annular member rotating with thespindle and located between said annulus and said braking surface, so that rotary movement of the annulus in the direction of the spindle rotation and consequent axial movement of the annulus and plate member operates to press said annular member against said braking surface with a variable
  • a braking arrangement according to claim 1, wherein a driving wharle is fixed to said spindle and said annular member rotating with the spindle comprises an annular extension extending radially from said wharle, and said stationary mounting assembly includes a cylindrical casing surrounding both the annulus and said wharle extension and a cap member on said casing extending over said wharle extension and carrying said annular braking surface.
  • a braking arrangement according to claim 4, wherein said casing is provided With a horizontal slot and said means for rotating the annulus comprise an arm con- 1 nected thereto and projecting through said slot.
