Definitions

  • the present invention relates to the combination of a guide arm with a cradle for the upper apron of a double apron drafting arrangement of a spinning machine.
  • double apron drafting arrangements for drafting fibre material of great staple length cradles of great length are required.
  • the conventional cradles rest on either side of the top rolls and are usually guided by saddles which are swingably accommodated in a'guide arm.
  • the cradle laterally abuts against the guide arm and is accurately guided in the plane of the drafting field and is swingable in a part plane normal to the drafting field.
  • Guidance of the cradle by the guide arm is preferably effected by providing the cradle with lateral protuberances which project toward and engage with vertical lateral surfaces of the guide arm.
  • FIG. 1 is a diagrammatic part-sectional side view of a guide arm and cradle arrangement according to the invention.
  • FIG. 2 shows a section of the arrangement shown in FIG. 1, the section being made along line IIII of FIG. 1.
  • FIG. 3 shows a part section of the arrangement shown in FIG. 1 and made along line IIIIII of FIG. 1.
  • numeral 1 designates a guide and weighting arm having an inverted U-shaped cross-sectional con- United States Patent figuration.
  • This arm carries a twin .top roll 2 including a connecting shaft 3 whereon rests a cradle 5 for an upper apron 14.
  • the cradle 5 is provided with suitable recesses 4 for receiving the shaft 3.
  • the cradle 5 comprises a U-shaped frame 7 having lateral walls 6.
  • the frame 7 has lateral extensions 8 to which outwardly acting resilient apron guides 9 are connected.
  • An apronreversing roller 10 is mounted on the forward end of the cradle.
  • the walls 6 extend outside of and beyond the lower edges of the lateral walls 11 of the guide arm 1 when the assembly is in operating position.
  • the walls 6 are provided with bosses 12 and 13 extending toward the walls 11.
  • the bosses 12 and 13 are as widely spaced as possible and slidingly engage with the walls 11, permitting swinging of the cradle in a plane normal to the plane of the drawing field.
  • the bosses however, definitely prevent swinging of the cradle parallel with the plane of the drawing field.
  • a top roll carried by said guide arm and forming part of said.
  • a cradle for said upper apron said cradle having a pair of walls opposite said .opposed surfaces and a portion resting on said top roll,
  • each of said walls for slidably engaging a respective one of said surfaces for affording movement of said cradle relative to said guide arm and in a plane normal to the plane of said drafting field and preventing movement of said cradle in a plane parallel with the plane of said drafting field.
  • a double apron drafting arran'gement for spinning machines means defining a plane drafting field and including an upper apron
  • a guide arm having a pair of oblong opposed surfaces
  • top roll carried by said guide arm and forming part of said means defining a plane drafting field, said apron surrounding said top roll,
  • each of said Walls for slidably engaging a respective one of said surfaces for affording movement of said cradle relative to said guide armin a plane normal to the plane of said drafting field and preventing movement of said cradle in a plane parallel with the plane of said drafting field.
  • said means provided on each of said walls comprises a plurality of bosses projecting toward said opposed surfaces, said bosses being arranged in longitudinal manner with repect to said walls.
