Definitions

  • Lead compasses are already known in different embodiments.
  • the lead compass according to the inven tion is distinguished from the well-known constructions in that the one leg consists of a holder for the pencil, with which holder the other leg of compasses is'pivotally connected in such a way as to enable it to be turned from the operative position into an inoperative condition, whereby the needlepoint lies close against the holder.
  • a ring can be provided slidably around the holder, which ring is adapted to receive the needlepoint in its inoperative position.
  • the holder can be provided with a longitudinal groove or slot for receiving the needlepoint in its outoi-work position.
  • Fig. 1 is a side elevation of a lead compass according to the invention, in which the needlepoint and the protecting ring are illustrated in two positions,
  • Fig. 2 is a plan view with the needlepoint in the operative position
  • Fig. 3 is a bottom view
  • Fig. 4 is a side-elevation at a smaller scale of a lead compass according to the invention, whereby the needlepoint is indicated in full lines in the work position and in dashdotted lines in the inoperative condi tion.
  • a tube-shaped holder 1 forming the one leg of compasses and carrying the pencil, is provided at one end with two lugs 2 forming a bearing for a hingepin 3 about which the other leg of compasses 4: with the needlepoint is rotatable.
  • the holder is surrounded by a split ring, 5, which is slidable over it till the two stops 6.
  • the holder has further a groove 7 for the needlepoint.
  • the leg 4% is turned round the pin 3 with the needlepoint in the groove 7.
  • the latter is provided at one end with a projecting collar 12.
  • a leg forming a pencilholder a second leg provided with a needle point, a pivotal connection between the legs so as to enable the needle point to be swung from the operation position in a position close against the holder and a ring slidable over the holder and adapted to receive the needle point in the latter position.
  • a leg forming a pencil holder, a second leg provided with a needle point, means pivotally connecting the legs to one another in such a manner that the le carrying the needle point may be turned from the operative position into an inoperative position, in which the needle point lies close against the holder, the holder being provided with a longitudinal groove in which the needlepoint lies in its inoperative position, and means movable over the holder and adapted to receive the needlepoint in its inoperative position.
  • a leg forming a tube shaped pencil holder and provided at one end with two lugs, a hingepin mounted in the lugs, a second leg rotatable about the hingepin and provided with a needlepoint, a ring surrounding the holder-and slidable in longitudinal direction over the holder,
  • a leg forming a tube shaped pencil holder and provided at one end with two lugs, a hingepin mounted in the lugs, a second leg rotatable about the hingepin and provided with a needlepoint, a ring surrounding the holder and slidable in longitudinal direction over the holder, stops on the holder limiting the sliding movement, a rib on the ring, the holder having a groove for the needlepoint and a projecting collar on the holder-preventing the ring from sliding oii.
  • a leg forming a tube shaped pencil holder and provided at one end with two lugs, a hingepin mounted in the lugs, a second leg rotatable about the hingepin and provided with a needlepoint, aring surroundin the holder and slidable in longitudinal direction over the holder, stops onthe holder limiting the sliding movement, a rib on the ring,'the holder having a groove for the needlepoint, a projecting collar on the holder preventing the ring from sliding off and a crosspin fixed to the ing a groove for the needlepoint, a projecting collar on the holder preventing the ring from sliding off, a crosspin fixed to theleg provided with the needlepoint and the inner side of the leg with theneedlepoint having a recess, substantially as and for the purpose set forth.
