Definitions

  • This invention relates to apparatus for attaching pronged devices, such as pronged fastening hooks and staples for wearing apparel, to fabric or other flexible material, said pronged devices being of the kind in which the prongs of the prong-carrying part are designed to enetrate through the material and to be then clenched or folded-over in order to secure the device in place.
  • the invention is more particularly concerned with such apparatus which includes a mandrel in the form of an elongated bar or plate provided with an associated pronged clenching part or parts, said mandrel being insertable into a pocket or sleeve portion of a garment, such as a trousers waistband, so as to facilitate the attachment of the pronged devices thereto.
  • An object of the present invention is to provide an improved construction of such apparatus which is adapted for automatic operation.
  • Another object is the provision of effective means for mechanically loading the mandrel with back plate components of the pronged devices, said means being particularly suitable for an apparatus designed for simultaneous attachment of a plurality of pronged devices.
  • the mandrel may be mounted as a cantilever with a slidably mounted movable supporting member under its free end which is arranged to be moved into supporting engagement immediately prior to the clenching operation, and which is withdrawn to an inoperative position in order to leave the mandrel free for insertion into the pocket or sleeve portion of garment material.
  • the mandrel may itself be movably supported, so that it is displace'able between an operative supported position and a free unsupported position in which it is adapted to be inserted into the pocket or sleeve portion.

In the operative clenching position, this carrier arm extends forwardly and substantially horizontally, as indicated in FIGURE 3, but after each attachment operation it swings back through an angle of approximately to a rear loading position shown in FIGURE 1 so that the working space above the mandrel 7 is normally clear and unobstructed.
  • the backing plates 5 are substantially rectangular in shape and are fed to the anvil recesses 8, 8 on the mandrel from a suitable storage magazine 11, as hereinafter described, whilst the staples or eye components 1 are fed to, and inserted or loaded simultaneously in holders 12, 12, of the carrier arm 10 whilst the latter is in its aforesaid rear loading position.

  • the staples 1 are loaded into the holders 12, 12, whilst the carrier arm 10 is in this rear position but in the clenching operation, the carrier arm swings in a vertical plane, forwards and down into a substantially horizontal position as previously mentioned in which the staple holders 12, 12 are directly above the anvils 8, 8 on the mandrel 7.
  • each staple 1 in the holders 12, 12 is then ejected by being driven downwards, which action causes the prongs 2 to penetrate through material laid over the anvils 8, 8, the prongs then passing through the apertures 4 in the backing plates and being clenched over by inclined clenching surfaces within the anvil recesses.
  • FIGURE 3 illustrates the carrier arm and operating parts immediately before actuation of the pressure lever 43, and ejector plungers 40.

  • the carrier arm is arranged to be actuated by the clenching cam 27 on the common camshaft 14 through a lever and linkage system.
  • the clenching cam 27 is engaged by a cylindrical cam follower 53 carried between opposed ends of a pair of parallel, spaced-apart levers 54, 54, of inverted V-shape which are pivoted at their other ends on a forwardly-positioned cross shaft 55 mounted on the side plate 32 between which the carrier arm 7 is pivoted.
  • This guideway 73 is formed by a channel in a sloping front face of a block 75 secured on the top face of the associated pillar 19 and the staples 1 enter into this guideway 73 with their prongs 2 directed upwards and outwards from a rearwardly-extending delivery channel 76 supplied by a continuous feeding device external to the press.
  • the staple loading feed slide 72 moves across, as shown in FIGURE 5, and pushes the staple laterally into the adjacent carrier tarm holder 12, through the open side of the latter. In so doing, the feed slide 72 closes the end of the delivery channel 76 so that another staple cannot enter into the guideway 73 until the slide 72 is retracted on completion of the loading operation.

  • this may be a magazine type of device
  • another form of device which ha been found satisfactory utilizes a vibrator drum, that is, a hollow drum having a base part which is vibrated through elect-ro-magnetic means so as to impart a unidirectional movement about the vertical axis of the drum to small objects placed thereon.
  • the movement of the objects is constrained by the upstanding side wall of the drum and such devices are well known for use in sorting and feeding small objects, such as nuts and bolts for example.

Staples placed in the drum then automatically arrange themselves around the side wall 96 and become fed upwards along the inclined guide tnacks 97 under a light forwards pressure.
  • the staples become correctly orientated in line, with their prongs 2 presented upwards, although any staples which do not orientate themselves, by reason of a dimensional defect or otherwise, will normally be displaced and will fall back to the base of the drum before they reach the top of the tracks 97.
  • the width of the tracks or ramps is substantially the same width as the bar 3 of the staples, and a gate (not shown) formed by a projection or guard may be positioned above each of the tracks or ramps 97 finally to ensure that no staples are passed on which are not correctly orientated.
  • top outlet ends of the tracks or ramps 97 may be joined to the delivery channels 76, 76, of the press by separate connecting bridge channels 99 along which the end-to-end line of staples is fed.
