Definitions

  • the present invention aims to avoid these objections and comprises the novel method of procedure and core or mandrel for carrying out such process as hereinafter'described and particularly defined by the appended claims.
  • the former or mandrel which is indicated as a whole at A, and which may be constructed of any suitable material, is preferably made hollow and of general exterior dimensions corresponding to the interior dimensions of the cell to be formed thereon.
  • the bottom of I the mandrel, or portion which is utilized to form the cell bottom 'or base, is provided with transverse grooves A, which are designed to receive and sup- Specification of Letters Patent. Patented Apr. 18, 1922.
  • a preformedand partially vulcanized base may be used having integral ribs 01' bridges or a hand made base may be used, in which event strips of bridge forming material are first placed in the grooves and thereafter the bottom forming layer applied.
  • the wall stock is then wrapped around the mandrel, enough of the wall stock extending beyond the base to allow for trimming and turning down in order to form the base seam and unite the base and walls. 4
  • the wall stock is thereafter rolled down with a suitable roller, the wrapping and rolling process causing the stock to hug the mandrel.
  • Such isolated portions may consist ofi longitudinally disposed ribs A which, in the mandrel shown in the drawing, are formed by providing the mandrel with longitudinal flutes or grooves L.
  • the walls of the former would be of skeleton formation, as the manner in which the raised stock supporting surfaces are con-' nected is immaterial.
  • the stock is wrapped and rolled upon such a mandrel it is supported upon the raised surfaces and numerous intervening underlying channels are provided which communicate with the atmosphere and allow the ready escape of air and gases caused by the vulcanizing heat.
  • the hereindescribed method of forming vulcanized battery jars which consists in applying sheets of unvulcanized material to a former having its surfaces provided with a plurality of raised portions for supporting said sheets spaced from the remaining portions of the former, vulcanizing the article, and then stripping it from the former.
  • vulcanized battery cells which consists in applying sheets of unvulcanized material to a former, subjecting the same to a vulcanizing heat, and simultaneously venting the space between the former and cell walls, and finally stripping the article.
  • vulcanized battery jars which consists in assembling sheets to form the jar walls and bottom and supporting the side wall sheets, during such assembling, at a plurality of parallel lines, vulcanizing said sheets while so supported, and thereafter removing the article from the support.
  • a core or mandrel for mal ingvulcanized battery jars having its walls provided.
