Definitions

  • This invention relates to bobbins and holders therefor.
  • Known bobbin holders must be placed in the bobbin with little play, with disadvantageous results in that-the holder grips the bobbin tightly so that the wound rayon cannot be removed without damage or at any rate only with difficulty. tween the bobbin and the holder then the bobbin has, during its rotation, no fast grip and thus knocks,'runs eccentrically and even rebounds.
  • the present invention discloses a novel form of bobbin in combination with its holder, which makes it possible for the bobbin to be secured on the holder with a determined amount of play, but nevertheless ensuring an absolute fast grip of the bobbin thereon, so that the latter can neither knock nor move centrifugally.
  • a bobbin holder for artificial silk spinning ma chines is characterised in that the inner sleeve of the holder is constricted near its central part like a cylindrical handle and the bobbin is secured to the holder by means of cams one of which is yielding, oneseries of cams being pressed against a rear cylindrical part and the other against a forward conical part of the bobbin.
  • Fig. 1 is a longitudinal section through the bobbin and holder on the line I--
  • the cams ⁇ and 9 have respective bevelled surfaces H and I2 in order that they struction of the outer sleeve frame lb, irrespective whether or not a rigid or an e'xpansible bobbin I be concerned.
  • Said frame which forms a skeleton sleeve comprises the longitudinal bars of said sleeve Ia are tapered or converge towards the center part lflb of said sleeve and terminate at each end thereof in a cylindrical or approximately cylindrical section I90, I9d.
  • This construction of the inner sleeve la ensures, in combination with the co-operating bobbin holder 4 a secure holdingmeans for bobbin 1.
  • the cam 8 of the lever 5 of the bobbinholder 4 presses against the inner cylindrical section l9c of the bobbin sleeve 1a while the other cam 9, adjacent, the free end of holder 4, engages the bobbin sleeve la at the end portion l9 of sleeve Ia and so urges it towards the shaft 3.
  • This latter cam 9 protrudes only so far from the holder 4 that it contacts with the converging end portion l9, while sufficient space is left for the bobbin 1 to be taken hold of with the hand by the spin- -nerfor the purpose of removing it.
  • the present invention aims at preventing this and, to,this end, the'partsf I6, 20 and 2
  • auxiliary edges l1, IS.
  • the bobbin can then'be stood up on these This edges l1, l8 respectively, and not on the edges II, M. Damage of the auxiliary edges cannot harm the thread.
  • the real edges l3 and I4 are thus protected and remain always smooth and the spinning of the. silk can proceed without or be projected forwardly Especially cam 9 pre-.
  • bobbin 1 is held by yielding,'pressure members or cams 0, 9 and also by the forwardly disposed rigid pressure members or cams b, b.
  • Hollow attachment 4 has two inwardly projecting lugs a: to limit lateral movement of U- shaped member or lever therewithin.
