Definitions

  • This invention relates to improvements in wire staples for tacking apparatus of the kind known fas staplers which are commonly used for tacking together two or more layers or sheets-of paper or other flexible materials such as leather, cardboard or the like.
  • the wire staples or tacks used for such purposes (which will hereinafter be ⁇ referred to as staples or tacks) comprise one or more legs with points extending from a com-mon back or cross piece andare adapted to be .pressed through the paper sheets to be tacked together by means of the tacking apparatus (hereinafter referred to as the tacker).
  • This apparatus is usually provided with an anvil adapted to bend the two legs or ilaps together when the tacker is pressed down towards the surfaces to be tacked together.
  • the main object of the invention is to provide means facilitating ready removal of the tack from the paper without the use of tools after the back was pressed through the paper sheets and bent at the rear side thereof.
  • the back or crosspiece of the tack is provided with a transverse incision, a slot or similar means, the cross piece weakening means being in or adjacent the center of the cross piece between the flaps or legs and arranged before the tack is pressed through the paper.
  • Such weakening means will cause the back or cross piece to 'break easily by bending which can be effected without diiiiculty with the fingers after the fastening or tacking operation has been concluded, as the paper will easily permit of the back or cross piece being bent 90 or more.
  • the back will also break by a repeated bending forwards and backwards at a similar angle.
  • a chisel-like tool is the best suited piece of tool for producing the incision in the cross piece, and in the case of the type of tacks produced from a flat wire and usually assembled to a coherent strip of a length according to the structure it'is easier to produce the incision after assembly e. g.
  • the Weakness m'ay be produced in any other way than by means 'of incisions without departing from the scope of .the invention e. g. by a hole through the back or by providing one of the surfaces of the back with a pyramid or cone shaped cavity .of a nature next to a centre punch hole.
  • the 'preferred embodiment is the one where the incision is arranged on the side of the back facing the paper after tacking because the easiest way to make the angular bending of the back intended to cause the breaking is by pressing the centre of the back with a finger nail against the paper and supporting the bent aps or legs of the tack on the opposite side of the paper by means of two finger tips, and as the incision Will thus be on the top of the angle formed by the back during the bending the crack, which is the beginning of the breaking, will arise so much easier when it emanates from the sharp bottom of the incision.
  • tack marking may also be effected by a pattern pressed into the upper surface or side of the cross piece e. g. by means of a roller which during the process of providing the weakening incision in rows of tacks presses the tacks against the roller for producing the incision.
  • FIG. 1 shows a side elevational view of a tack.
  • Fig. 2 a side elevational view of another tack.
  • Fig. 3 is a top plan view of the tack of Fig. 1.
  • Fig. 4 is a side view of a tack inserted into superposed sheets of paper and with bent legs or flaps.
  • Fig. 5 shows the same tack of Fig. 4 after bending to cause breakage of the tack.
  • Fig. 6 is the same tack of Fig. 5 after breakage thereof.
  • Fig. 7 illustrates how the halves of the same tack are detached from the paper.
  • Fig. 9 shows in perspective a strip of tacks with a marking stripe.
  • Fig. 1 is seen the back or cross piece I from which the two legs or aps 2 extend.
  • On the underside or surface 3 of the back is an incision 4 for the purpose of weakening the back I
  • Fig. 2 is shown another embodiment where the weakening means is formed by incision 4 arranged at the under surface f as well as on the top surface 5 of the back I.
  • Fig. 4 shows a tack inserted into two superposed sheets of paper I at the under surface of which the two legs are bent toward each other.
  • the incision 4 is at the under surface 3 of the back I which in Fig. 5 has been bent at an angle to thereby cause a crack or breakage 8 to extend from incision 4 to the upper surface 5.
  • Fig. 8 shows a strip of assembled tacks in which the incision 4 is arranged at the bottom or under surface 3 of the back I
  • Fig. 9 shows in perspective a strip of tacks provided on the top surface 5 with a marking stripe 9 to indicate the location of the incision 4 in the under surface of the tack.
  • a bendable staple of the character described comprising a cross piece, two legs extending at substantially right angles from said cross piece, said cross piece being provided with material weakening means extending into the under surface of said cross piece and adjacent the center of said cross piece, and means located on the upper surface of said cross piece and indicating the position of the material weakening means in the under surface thereof.
