[Illustration: FIG. 86.] The following description applies more particularly to the model of 1883, which differs in some of its details from previous models. The 1-inch and .45-inch calibres are now in service; and contracts have been made for supplying .30-inch calibre. The Gatling gun consists of a number of breech-loading rifled barrels, _B_, grouped around a shaft, _S_, to which they are parallel. The 1-inch has six barrels; smaller calibres eight and ten. Each barrel is fired only once in the revolution of the group. [Illustration: FIG. 87.] The breech-ends of the barrels are screwed into a disk or rear barrel-plate, _P′_, which is fastened to the shaft, and the muzzles pass through another similar disk, _P_, called the front barrel-plate, on the shaft; the shaft projects beyond the muzzles, and extends backwards for some distance behind the breeches of the barrels.
