Definitions

  • My invention relates to Cartridges having an internally -grooved metal base or head formed separate from the body of the Cartridge and subsequently attached thereto.
  • the object of my invention is to provide new and ilnproved means for securing the body of the Cartridge to the base; and to this end the invention consists, essentially, in the combination, with an internally-grooved head or base and a tubular Cartridge-body, of an expansion-piece which is integral with the base or head and a second divided or slitted metal eXpansion-piece which is not integral with the base or head and which is inclosed by the forrner whenthe same is expanded and retains the Cartridge-body in the groove of the head, as will more fully hereinafter appear.
  • FIG. 1 is a longitudinal sectional view of a Cartridge constructed in accordanoe with my invention.
  • Fig. 2 is a detail sectional view of the internally-grooved head or base.
  • Fig. 3 is a detail view of the second divided or slitted metal eXpansion-piece; and
  • Fig. 4 is a longitudinal sectional view of a Cartridge, showing a reinforcing gas-Check arranged in the base of the Cartridge.
  • the head or base B' is formed integral with the expansion piece or ring F3, located in juxtaposition to the annular internal groove Z).
  • the letter F indicates the divided or slitted metal expansion piece or ring, which is not integral with the head or base B'.
  • the expansion piece or ring F is shown circular in Cross-section.
  • the Cartridge-body A In applying and securing the Cartridge-body A to the base or head B' the Cartridge-body is inserted into the head or base and the divided or slitted expansion piece or ring F is forced downward to turn the bottom edge of the Cartridge-body into the internal annular groove b, after which the edge of the expansion piece or ring F3 is bent or turned over ⁇ the expansion piece or ring F to more firmly and securely hold the latter in place, as will be best seen by reference to Fig. 4.
  • the Construction shown in Fig. 4 is the same in all substantial respects as that shown in Figs. 1, 2, and 3, with a reinforcing gas-check J as applied thereto.
  • the extreinities of the divided or slitted expansion piece or ring F are turned up, in order to enable it, when eX- panded radially outward into place in the bottom of the groove b, to bear all around against the interior of the Cartridge-body.
  • the upturncd ends of the ring are of course depressed and abut one another when the ring is expanded.
  • the separate expansion piece or ring F, secured by the expansion piece or ring F3 securely holds the Cartridgebody to the Cartridge base or head.
