Definitions

  • This invention relates to the manufacture of shoes and particularly to the fastening together of shoe parts.
  • Tacks, nails and other forms of metallic fastenings have long been commonly used for securing together various parts, both temporarily and permanently, in the manufacture of shoes. While there have beenv a number of objections and disadvantages arising from the use of such-metallic fastenings, these fastenings have been so easy to insert and so generally convenientthatit is probably safe to say that, aside from moccasins and the various types of rubber footwear, shoes have never been made on any considerable scale by any of tlre. usual presv ent day methods Without extensive use of metallic fastenings.
  • the number of needles give it the strength it should have, it must be continuous from end to end.
  • the metallic slugs commonlyinserted in the top lifts of leather heels and the metallic tacks and nails used to secure the top lifts to wood h els are other examples of metallic fastening which are not entirely satisfactory. These tacks, nails and slugs perform a neeessar parts of/ the heels, and, in the case of slugs, also produce an ornamental effect which is not without value as a selling point. Also, they serve to an extent as a reinforcement. On the other hand the use of such fastenings results inthe consumption of an excessive amount of sand paper during the top lift scouring operation, and, when shoes having such heels are worn, results in a great deal of damage to highly-finished floors.
  • the shoe upper is strained to shape it over the last and to position it'in lasted relation to the insole, and is secured in that relation to the insole by inserting paper pegs through the upper into ⁇ the insole, and heading said pegs so as to prevent the comparatively thin upper stock from pulling Off over the ends of the fastenings.
  • This may be done, for example, by using fastenings a little longer than the depth of the holes in the stock into which they are inserted. so ⁇ that their enteringends reach the b0ttoms.
  • the paper twine may be impregnated with sizing material such as glue. This is commonly done in the manufacture of paper twine by passing the aper strip prior to its twisting lthrough a Bath of sizing material or'over a roll which passes through such abath.
  • sizing material such as glue.
  • the paper pegs will be improved for many purposes if the sized twine from which they are eut is given a supplemental coating of sizing material after it has been twisted and dried. This supplemental surface coating of sizing under certain conditions increases the ⁇ holdingpower of the fastenings.
  • the supplemental coating may advantageously be of water-soluble glue lin which case some of the glue will be dissolved and will tend to cement the fastenings into place. If thefastenings are to be driven into dry stock they may be moistened immediately before being driven with the same advantage.
  • a surface coating of a more than ordlnarlly water resistant glue o r sizing may be used, for example a Water-resisting casein glue, animal glue to which j dchyde or a dichroinate, or sliellac.
  • a surface coating of a more than ordlnarlly water resistant glue o r sizing may be used, for example a Water-resisting casein glue, animal glue to which j dchyde or a dichroinate, or sliellac.
