Definitions

  • the present invention relates to wire coil infserts' for screw connections of the type described,
  • tions are free for engagement'. by the threading of a stud or bolt member.
  • '.lhe well-known inserts are provided with a diametrical tang of its end convolution so arranged that the tang can be broken offl after the insertion of the coil is Y completed. In many instances, however, this is not a desirable design inasmuch as the tang constitutes a waste, as it is diilicult'v to break' the tang if the wire has a substantial thickness and as it is diiiicult in many instances to remove the broken tangwhen the hole into which the coil is-inserted is ablind one. 4
  • the present invention 'contemplates to provide means whereby the mentioned disadvantagescan be avoided and essentially consists in that one coil end isv provided with a recess on the inner side lof the convolution 'so that a hook-shaped end is produced which does not project from the desired shape of the coil.
  • Pig. l is a perspective view of a wirecoll according to the invention.
  • Fig. 2 is a irontv view of a modified portion of v the recessed end
  • FIG. 3 is a perspective view of another embodi4 men r v 'Referring now to the drawing, ⁇ Fig. 1 shows a wire coil in general denoted by I which'has a v diamond-shaped cross-section. However, it is to l be understood that the invention is applicable to, coils of wire cross-'section of any form such as round. square or pear-shapedy cross-section.
  • the one end convolution 2 of the coil is provided with a recess 3 on its inner side andthe flank l of the recess close to the ultimate end of the convolution is located in a .plane substantially'radial With 'lpt V to the coil axis I.
  • vIt is advantageous a in many to make the ⁇ mentionedminister undercut asl indicated at la inthe modincationof t a tool witha radial projection inserted into the ⁇ coil may engage the ilank 4 safely.
  • sumcient material of the'recessed portion should remain to transmit the torque applied by 5 the tool at the ank l to thecoil convolutions in order to contract the coil for insertion. In most instances, a recess depth of approximately half the wire thickness will be adequate.
  • the end face 3 of convolution g may be slanted 1o so that an inner edge 1 is provided which may bolt screwed into the 4 l bite into the material of a insert-in order to'create a locking eiect.
  • said coil being provided with a recess on its inner side near its free end, said recess having a depth of approximately half the wire thickness and having a substantially radial ilank adjacent to said free end so as to form' a hook for the ensement oi a torque-applying tool.'1 f
  • An insert for a screw connection comprising one end convolution of said coil havinga decreasing diameter so that it projects inwardly with respect to the inner coil cylinder, said projectins portion being provided with a reoesson its inner side near itslree end.' and said recess having a depth ot approximately halt the wire thicknsu and havins a substantially radial nank adjacent to said tree end.
