Definitions

  • teaser VICTOR DESGHIENS or PARIS, FRANCE, ASSIGNOR T0 JOSEPH FRANCOIS ESTEBAN- nnxnorins, or lARIS, FRANCE.
  • Iris type which comprises a corkspoolor bobbiirshaped member having its intermediate portion fitted with a band of paraflined felt.
  • I construct the two end'portions or disks and the interi mediate portion or core of separate pieces of cork or similar material, and I fit the core with a band of felt or other suitable substance which is impregnated with an agglutinant such as paratlin that will soften and fuse under the heat of the gas of explosion when the cartridge is fired.
  • an agglutinant such as paratlin that will soften and fuse under the heat of the gas of explosion when the cartridge is fired.
  • the three parts specified are fastened together by means of the paraffin for convenience in loading the cartridge; but such attachment. however, will be terminated by the melting of the paraffin, as above explained, and the parts will separate on leaving the barrel.
  • This detachment will enable the parts to respond more effectively to the impulse to which they are subjected, while at the same time preventing any danger of the wadding sticking in the barrel: and it also serves to reduce the weight of the wadding which is opposed to the spread of the shot, so that the ballistics are improved.
  • the core itself constitutes an effective gas check, since it expands in consequence of the pressure imposed upon it and, in turn. causes its felt strip to bear against the wall of the barrel, thus preserving to the full extent the velocity, penetrating force and carry of the charge.
  • the construction of the improved wadding can be carried out in various ways, ac-
  • the first cork disk is placed in a metal mold of the proper caliber which rests on a plate also made of metal.
  • the intermediate disk or core which is itself of appreciably smaller diameter than the first disk, but which is rendered of equal diameter therewith by the addition of its peripheral band or strip of felt, is then placed on the first disk and a suitable agglutinant, preferably paraffin, is poured into the mold, whereafter the third or top disk 1s positioned on top of the intermediate disk before the agglutinant has completely cooled and hardened, thus binding the three disks together. Removal of the wadding from the mold may beeffected by the chuck-or mandrel of an automatic or pedal-operated gauge.
  • the resilient cores previously fitted with their felt strips. may be introduced into suitable molds and then paraflined in the manner above explained. after which they are carefully removed and boxed say by the hundred or two hundred; double the number of end disks then being packed in a separate compartment in the same box. At the moment of loading, it is sufiicient merely to interpose a core between two of the larger end disks; this operation occasioning no confusion and being much simpler and easier in fact than the ordinary operations of assembling and loading multiple-part waddings which frequently embody from six to eight different component members, some of which are difficult to distinguish.
  • Figure 1 represents the three component parts of the improved wadding separated from one another
  • Fig. 2 represents the parts assembled, but without the felt strip on the intermediate part or core;
  • Fig. 3 is a vertical section through the finished wadding
  • Fig. 4 is a side elevation thereof.
  • B and G indicate the two end disks of the wedding
  • E the intermediate disk or core which is of appreci ably smaller diameter than the first two disks, all three disks being made of cork or other suitable resilient fibrous material.
  • These parts may be of any desired shape and size (one of them may be frusto-conical) according to the results to be obtained, and the end disks may be recessed or apertured in order to facilitate the introduction and seating of the core, while the latter may be perforated for the purpose of increasing both the propulsion and the checking effect by the action of compressed air.
  • the cor E is encircled by the band or strip D of felt or the like which is subsequently impregnated with paraffin or other suitable agglutinant, as explained above.
