Definitions

  • This invention relates to a method of making hollow bodies of circular cross section having openings left therein, and particularly cylindrical bodies of irregular cross-section such as, for example side-cars of motor-cycles.
  • the method of building hollow bodies according to the invention consists in fitting strips of wood around a last-shaped body, winding a rope of fibrous substance over and gluing it to said strips. placing an outer layer of wooden strips on the coiled rope and finally binding said outer layer by coiling a wire rope around and subsequently removing the wire rope after the hollow body has dried.
  • Figs. 1 am 2 show in side elevation partly in section and in end view respectively the last-like form.
  • Fig. 3 shows the hollow body partly cut away so that the several layers are visible of which the body is composed.
  • Fig. 4 shows in side elevation the finished hollow body for a side car.
  • Fig. 5 shows in vertical section the front end of the finished hollow body.
  • Fig. 6 shows in cross section the several superposed layers during the manufacturmg.
  • rings which, as shown in Figs. 1 and 2, are joined to form a last for the hollow body to be made.
  • Two end disks 2 of the form will preferably remain in the hollow body and they are pressed against the rings 1 by means of a longitudinal rod 4.
  • pins- 5 are preferably inserted into the adjacent faces of said rings.
  • the rings are of such thickness that they can be easily removed through the entrance opening 6 (Fig. 4) of the finished body.
  • the lastlike. form is rotatably mounted as shown in Figs. 1 and 2 in a bracket 7, and it is advisable to mount upon the rod 4 a belt pulley, by means of which the last like form can be intermittently and slowly rotated.
  • this layer of rope 9 On this layer of rope 9 a layer 10 of wood boards is placed which correspond. as regards shape and construction. essentially to the Wood layer 8.
  • this layer forms the outer shell of the hollow body.
  • a method of building hollow bodies of circular cross-section having openin s and the like consisting in fitting strips 0 wood around a last-shaped body, winding a rope of fibrous substance over and gluing it to said strips, placing an outer layer of wooden 1 strips on the coiled rope and finally binding said outer layer by coiling a wire rope therearound and subsequently removing the wire rope after the hollow body has dried.
