Definitions

  • the invention has for its object to overcome these drawbacks, which object is achieved primarily the brake band employed being arranged so as to be swung about a fixed point, a spring accumulator being interposed which owing to its elasticity is adapted so to displace at least the one point of suspension of the brake band in accordance with the power actuating the brake, that the brake band embraces a greater or smaller section of the periphery of the brake disc. While hitherto the brake band whether attracted either by a great or by a small power, always touched the same section of the periphery of the brake disc,
  • the surface on which the band and the disc touch one another entirely depends upon the power employed, so that as long as only a small power is exerted, the braking surface is also small, While with increased braking power the braking surface increases also,
  • the one fulcrum of the spring accumulator may be fixed to the one leg of a bell crank lever which is axially shiftable against the action of a spring, while the other leg, which has i the shape of a segment and is provided with notches or holes adapted .to receive a fixed locking bolt, can be set in different positions, so that the fulcrum changes its position relatively to the brake disc.
  • Figure 2 is a View of the parts under consideration of a winding frame
  • Figure 3 shows the upper portion, of the Figure 2 with some parts in a different position
  • Figure 4 is a view similar to Figure 2 shows the other embodiment
  • Figures 5 and 6 show the appurtenant braking device in side and end view, respec tively, and on an enlarged scale.
  • a prefei ably endless brake band 6 embraces a portion of the periphery of disc 5 which band is fixed with one end at 7 and with the other end at 8 to both ends of a resilient carrier 9 made from a steel strip;
  • the carrier 9 constitutes the spring accumulator mentioned above and forms a loop at 10 bywhich it is hingedly fixed to a journal 11 while the other end of carrier 9 rests on a pull rod 12, Figure 1.
  • the two free ends of the brake band carrier 9 are bent off so as to have the brake disc 5 between them.
  • the pull rod 12 is under the influence of the thread guide 13, Figures 2 and 3, which guides the thread 14 on the rollers 15 to the winding bobbin 16.
  • Figure 2 shows the thread guide 13 in the tensioned condition, which is the case when the pull of the thread acting in the direction of arrow has increased.
  • This position of guide 13 causes, byineans of the connection of rod 12, the brake band 6 to assume the position shown relatively to the brake disc 5, in which position the brake band 6 is in contact with the latter only slightly or not at all.
  • journal 11 may be made adjustable.
  • the journal 11 is fixed to the one leg 17 of a bell.
  • crank lever 17, 19 which is fulcrumed at 18 amlthe other leg 19 of which forms a segment 21 having a series of holsjQO.
  • an axially extending handle 22 lever 17, 19 can be shifted in an axial direction against, the actionof a spring 23.
  • the lever 17, 19 can be locked in position by. a fixed bolt 21- engaging one of the holes 20, and released ,by retiring it on handle 22, whereupon it can be swung so that journal 11 can beraised or lowerechas indicated by arrows, Figure 5.
  • V means for adjustably setting said lever with respect to saidhrake disc, and means for varying the angular contact surface between said brake disc and band in accordance with the tension upon the thread unwound from the bobbin.
  • double armed lever mounted in the machine frame, upon which said carrier is pivoted, one of said arms of said lever carrying said pivoted joint 01 thecarrier, and a plurality of locking apertures on the other arm adapted to cooperateiwith a locking bolt to selec- .tively lock the double armed lever in different positions with respect to the brake disc, andmeans for varying theangular con tact surface between said brake disc and band in accordance with the tension upon the thread unwound from the bobbin.
