Definitions

  • Two-ended clothespins are known, in which projections and grooves are provided in the parting plane of the limbs, which projections and grooves interengage when the pin is in clamping position and forms articulated joints for the two limbs during the opening movement.
  • these projections and grooves are straight so that the required clearance between the tongue and groove results in a transverse twisting of the two limbs because a force tending to twist the two limbs will be applied to them when the two limbs are pressed between the thumb and forefinger of one hand. This twisting of the two limbs, however, is very disturbing when the clothespin is used in practice for fixing clothes or the like.
  • FIG. 1 is a top plan view of one jaw of the clothespin and FIG. 2 is a side view of the assembled pin.
  • the central portions of two elongated jaws or limbs 1 are held together in a known manner by a helical spring 2 and interengaging projections 3 and grooves 4 on the jaws form two pivots on opposite sides of the spring 2.
  • the axes of these pivots are perpendicular to the axis of the spring 2 and to the direction of elongation of the jaws 2.
  • the grooves 4 and projections 3 are curved and define curves, which are outwardly concave with respect to the axis of the spring 2.
  • these curves could be outwardly convex provided that their radius of curvature does not equal the distance of the grooves and projections from the axis of the coiled spring 2.
  • the essential feature is that any relative twisting of the two limbs will cause jamming between the projection 3 and groove 4 owing to the interengagement between the projection and groove, and this will prevent the relative twisting of the two limbs so that interengaging projections and grooves prevent a lateral slipping.
  • a two-ended clothespin which comprises two jaws and a coiled tension spring urging said jaws toward each other, said jaws being formed with normally interengaging portions constituting two articulated joints, the axes of said joints defining a plane, said interengaging portions of each joint including a groove and a projection, said grooves and projections being elongated and curved in said plane.
