  • the present invention relates to drawing mechanisms of textile machines.
  • top frames for the top rolls are usually turnably connected to the frame for the bottom rolls and is held in an operative position by a releasable catch. in this operative position, springs or the like urge the top rolls toward the bottom rolls so that these springs transfer their force to the releasable catch which must be engaged and disengaged against the action of these springs.
  • springs or the like urge the top rolls toward the bottom rolls so that these springs transfer their force to the releasable catch which must be engaged and disengaged against the action of these springs.
  • Many modern textiles require an extremely high pressure between the top and bottom rolls, and strong springs are provided for this purpose.
  • One of the objects of the present invention is to overcome the above disadvantages by providing a means for removing the influence of the springs on the releasable catch so that the latter can be very easily engaged and released.
  • a further object of the present invention is to provide a means for moving the top rolls, while the top roll frame remains stationary, away from the bottom rolls.
  • Another object of the present invention is to provide a means for moving only the front set of top rolls away from the drawing plane while the top roll frame remains stationary.
  • a still further object of the present invention is to provide a means for automatically maintaining the top rolls in a position spaced from the bottom rolls while the top roll frame remains in its operative position.
  • Still another object of the present invention is to provide a structure capable of accomplishing all of the above objects and at the same time being made of relatively few, ruggedly constructed parts.
  • the present invention mainly consists of an apparatus for use in a textile drawing mechanism and including an elongated support means turnably mounted on a base means of the drawing mechanism for movement to and from an operating position.
  • a rst elongated arm is turnably connected to the base means and extends along the length of the support means, this tirst arm turnably carrying a first pair of top rolls which have their axis located beneath the first arm.
