Definitions

  • Wads are also known comprising a cup associated with the conventional wads: in this case the concavity of the cup is turned towards the powder; said cup constitutes a standard pneumatic joint: under the gas pressure, the side casing of said cup applies against the side wall of the case and then against the gun, thereby preventing the gas leakages.
  • This type of wad makes the charging difficult, as the first element to be engaged is the cup, which may accidentally swing or which sometimes hooks on the rim of the case.
  • the oblique or inverted position taken by said cup does not ensure the tightness or sealing effect desired and, which is more serious, it is impossible to detect said deficiency when the charging has been efiected.
  • the present invention which aims to eliminate the above-mentioned drawbacks has for its object a wad comprising a tightness or sealing cup acting by distortion under the effect of the internal pressure, associated with guiding means for preventing swinging and facilitating the introduction of the case into the tube.
  • the guiding means consists of :a cup arranged back to back with the tightness or sealing cup, which in one embodiment is joined to the latter by any convenient means, such as rivet, glue, screw, and so on.
  • the wad comprising a tightness cup and a guiding cup is made in one piece i. e. the wad consists of a single part provided with two opposite cavities, one of which, turned towards the powder, constitutes the tightness cup while the other, turned towards the charge, constitutes the guiding cup.
  • the latter may be filled with any material, such as felt, board, sawdust, and so on.
  • Figs. 1 and 2 are longitudinal sectional views of two embodiments of a wad according to the invention.
  • the tightness cup 2 is disposed back to back with a guiding cup 3 after a disk 4 made of felt or similar material has been inserted.
  • the three parts of the wad are fixed together by means of a rivet 5.
  • Said rivet may be replaced by a bolt or other fixing means.
  • the constituent parts of the wad are thus separately made and then assembled.
  • the wad consists of a cylindrical body 6, with two opposite cavities 7 and 8, separated with the disk 9, the whole being made in one piece. That cavity which is turned towards the shots is filled with any material such as felt or sawdust.
  • the height of the guiding cup is so chosen as to prevent the tightness cup from swinging.
  • the wad may be easily adapted to the requirements of the charging with regard to the compressibility of the Wad which may be varied according to the speed of the powder.
  • the cup alone serving to ensure the tightness or sealing, no radial dilatation is required of the filling material which may be hard as board or as compressible as sawdust or granulated cork.
  • the maximum damping may even be obtained by maintaining the upper cup empty and by disposing on the upper edge thereof a strong board for supporting the shot charge.
  • a one-piece wad for effectively separating the powder from the shot in a shotgun cartridge case comprising a cylindrical tubular body having a thin pliable wall and a transverse partition integral with the thin wall located between the ends of the tubular body and dividing the body into two back-to-back cups, one cup serving as the guiding means for the wad in the cartridge case and the other cup serving as the sealing means in the cartridge case; the height of the guiding cup being of a size to prevent the sealing cup from swinging or axial misalignment within the cartridge case.
