Definitions

  • the present invention provides a dobby of the Hattersley type comprising a hook hinged to a baulk, the hook being adapted to engage with and withdraw from a draw-blade, and a rotationally mounted blade having a contact surface adapted to engage the hook when the hook is raised.
  • the clearance gap can be eliminated by additional motion, for example a rotary motion being imparted to the draw-blade in its rear dead center position.
  • Two hooks 3 and 3' are hinged to two end portions 1 and 1 respectively of a baulk 2.
  • support needles 5 and 5 are used which form part of a front needle system (not shown) which reads a pattern from a pattern card.
  • a pivotal lever 6 is hinged which is connected via a drawing means 7 to a shaft (not shown).
  • Reference 8 and 8 designate stationary crossbars and 9 and 9 indicate return impact blades which carry out back and forth swinging movement at the same time and to the same extent as the draw-blades 4 and 4.
  • Support blades 11 and 11' are mounted on rotary axes 10 and 10 respectively.
  • the contact surfaces 12 and 13, and 12' and 13 respectively form with respect to the tangent of the pivotal are A an acute angle B of a few degrees of e.g. up to 20, the surface themselves with hooks 3, 3 raised and support blades 11 and 11 pivoted in the direction of arrow A extending parallel to one another.
  • Notch surfaces 14 and 15, and 14' and 15, respectively, which are adjacent to the contact surfaces 12 and 13, and 12' and 13' respectively, preferably extend while the support blades 11, 11' are engaged, in or parallel to the connecting line between the axis 10 or 10 respectively and the center of rotation of the hooks 3, 3' in the end portion 1,-
  • a laminated spring 16 can be provided on the support blade 11, 11, which urges the hook downwardly.
  • support blade means pivotally secured to said support means, said support blade means having a support blade positioned between said support means and said pivot connection and having a first contact surface extending generally parallel to the axis of said pivotal securement and generally parallel to the direction of movement of said draw-blade means and adapted to move generally perpendicularly to said first surface of said notch into engagement therewith when said hook means is in said raised position, said support blade means further having a second contact surface extending transversely of said first contact surface and said direction of movement of said draw-blade means and at an angle B in the range of 0 to 20 to a tangent to the arc defined by the movement of said support blade, said tangent being generally perpendicular to said first contact surface.
