Definitions

  • This invention relates to a woodworkers clamp of the type where a hand grip is tightened by rotation to press two work pieces together.
  • German Patent Specification No. 1928490 there is described a screw clamp for a paper stack which has a tightening nut provided with threaded collets for rapid engagement with a pressure beam.
  • a woodworkers clamp having two clamping faces, the one face being part of an L-shaped arm and the other being mounted in a thread on a second arm, the second arm being slidably mounted on the first L-shaped arm, whereby rotation of the threaded portion tends to force the two clamping faces together, the improvement which resides in providing either an internal socket or an external nut to which a spanner can be applied to generate additional rotational force to the handle of the second arm.
  • the clamp of the invention consists of an L-shaped arm 1 having a first clamping arm 2 having a clamping surface 3.
  • the clamping surface is conventionally substantially flat, but may roughened for example by having a series of indentations thereon to assist in gripping of the work being clamped.
  • the L-shaped arm also has smooth elongated portion usually at right angles to the clamping section 2. This substantially smooth portion may have one side surface 15 roughened by indentations or teeth.
  • a sliding arm 4 of a second clamping piece having a second clamping surface 6 which like the first clamping surface may also be roughened.
  • the two clamping surfaces 3, 6 are arranged substantially parallel to each other.
  • the second clamping surface is mounted rotatably on the end of a threaded spindle 7 equipped with an external thread 8. This spindle passes through an internally threaded hole in the clamping arm 4.
  • the spindle is attached to a handle 11 such that rotation of the handle in a clockwise direction (as viewed from above) tends to force the clamping faces together and rotation in the opposite direction moves the clamping faces away from each other.
  • the handle attached to the second clamping surface is equipped with means to receive a lever so that added rotational force can be applied to force the clamping faces together.
  • Said means to receive a lever can for example either be a socket 13 or an external nut shaped portion 12.
  • the socket or nut may be of any conventional shape suitable to receive a spanner or key. This shape may for example be square, hexagonal or polygonal. Spanners of known type can be applied to either means to receive a lever and the spanner rotated in conventional manner.
