Definitions

  • Thi invention relates to ammunition, particularly to shot shells and contemplates the improvement of shot shells by the provision of more efiective and satisfactory wads, which wads, notwithstanding their superiority, are nevertheless comparatively inexpensive to produce.
  • the powder charge in the base of the shell tube is separated from the shot load above by a wad'column, comprising one or more disks or wads of a somewhat elastic material; Frequently a soft paper Wad is placed immediately over the powder charge and one or more hair felt wads are placed upon the paper wad and below the shot.
  • the wads should be of an axially compressible material, in order'to provide for enlargement of the powder chamber under the pressure generated by the combustion of the powder before the shot load begins to move.
  • Thewads should also expand laterally under the axial compression so that they will contact closely with the bore of the gun, and form a seal or gas check in the rear of theshot, thus preventing the penetration of gas under high pressure among the shot and consequent scattering thereof.
  • the wad material most extensively used hitherto is matted hair felt, such felt being formed by compressing with a certain amount of glue or size a mass of tangled hair fibres.
  • nearly all of the hair lies parallel to the surface of the sheet and the felt thus exhibits a minimum of compressibility in a direction at right angles to its surface. It is readily apparent that if a substantial amount of the hair were arranged in a di', rection perpendicular to the surface, a compressive force applied to the surface and axially to the hair would be much more effective in reducing the thickness of the felt and at the same time causing it to expand laterally.
  • One object of this invention is to utilize for shot shell wads a felt in which a substantial-partof the hair is arranged axially of the wad, that is, perpendicular to its flat faces.
  • Fig. l is an elevation partly in section of a shot shell illustrating one arrangement therein of the wads of the present invention.
  • Fig. 2 is another fragmentary sectional elevation of a shot shell showing a slightly different arrangement of wads.
  • Fig. 3 is a fragmentary sectional elevation of a shot shell showing another variation in the arrangement of the wads.
  • Fig. 4 is an enlarged detailed section of the wad material.
  • the invention contemplates a wad for shot shells in which a substantial ortion of the hair or other fibre is arrange axially, that is, generally parallel to the longitudinal axis of the shot shell and perpendicular to the faces of the wad.
  • the wad stock may comprise a center of a sheet of material having substantial tensile strength and elasticity, and also capable of having groups of hair fibres passed transversely th'erethru.
  • a Woven fabric preferably a coarse and loosely woven fabric, such as burlap is suitable for this purpose;
  • the hair 5 making up the body of the wad is arranged on both sides of the burlap center 6, and is passed upward and downward thru the weave of the burlap by the action of suitable punching needles.
  • a substantially homogeneous and reinforced felt is secured.
  • This process of manufacture permits of the use of shorter hair than can be matted into ordinary felt.
  • the rigidity and elasticity of the felt is readily controlled by mixing with the hair varying amounts of size.
  • Such felt also has the characteristic that i The felt is therefore quite compressible axially and expansible radially under axial compression. A more perfect gas check is thus formed than with ordinary felt wads.
  • the wads may be made of such rigidity that the customary paper over powder wad (Fig. 1) hitherto used to cover the powder and separate it from the felt wads above may be dispensed with.
  • Shot shells so constructed are illustrated in What is claimed is: I 10 Figs. 2 and 3.
  • a Woven fabric The thickness of the wads and the numcenter, a" felt of short hair secured to said her superposed to make up the wad column center whereby a portion of said hair passes 5 may be varied, as shown in the drawings, transversely through the fabric and a subto suit the requirements of different shells.
  • stantial portion of said hair is arranged to 15
