tridge of large caliber, thereby not only econoini-zing in ammunition, but reducing the noise of the explosion and enabling a marksman to become familiar with a certain Weapon and practice in places which would otherwise not A further object of 'the invention is to so construct the attachments that said attachments will not necessitate the alteration of the :Weapons to which they are to be applied, and, furthermore, to so construct the attachments as to insure accuracy of re.
Another object of the invention is to provide means for using the attachments in connection With either rim or center fire carridges.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, formin ga part of this specification, in which similarcharacters of reference indicate corresponding parts in all the figures.
Figure 1 is a side View of a revolver, parts thereof being broken away, illustrating the application of the attachments thereto, a portion of the hammer being in section. Fig. 2 is a bottom plan View of the auxiliary barrel employed. Fig. 3 is a rear end view'of the said auxiliarybarrel when in place in the firearm. Fig. 4 is a front elevation of the ejector employed.

A represents the hammer of the attachment, l the barrel, and C the ejector.
D represents the body of a revolver of the Smith da Wesson type or that type of revolver that is broken for loading and for the ejection of the shell. G repris the ejector-stem; E, the barrel of the revolver; F, the cylinder, and H the trigger.
The hammer A, thatis adapted to be substituted for the ham mer belonging to the firearm, is provided at the upper portion of its front face with a recess 10, the rear wall whereof is usually concaved, as shown in Fig. 1, and at the upper portion of the rear Wall of the recess 10 a cavity 11 is produced. This recess is adapted to receive the ringpin12. The forward end of the striking-pin is more or less beveled, so as to form astriking-poiut 13 at one side of the center of said pin, and the ring-pin is centrally pivoted at its rear in the said recess l() by means of a suitable pin 15. The rear central portion of the firingpin is preferably cylindrical, as shown in Fig. 1, and a rearwardly-facing shoulder 16 is formed at the side of the pivot of said pin, so that said pin when in one position may be used upon center-fire cartridges and upon being reversed can be used with equally good 'results upon rim-fire cartridges. The firingpin is held in proper position to enter the opening 17 in the 'frame or" the weapon and strike the cartridge at a proper point by directing the iringpin through the medium of a stud 18, provided with a head 18a, as shown in Fig. 7, which head has bearing against the uppermost shoulder 16 of the firing-pin, as shown in Fig. 1, and the body of the stud enters the cavity 11 in the hammer and is encircled byaspring 19, having bearings against the head 18a and the rear yvallof said cavity 19.
The barrel B consists of a body-section 20, that is slightly longer than the length of the main barrel E of the weapon, and a rear section 21, that is adapted to enter a chamber in the cylinder F of the weapon. The outside diameter of the body portion of the auxiliary barrel B corresponds to the inner diameter of a chamber in the cylinder F, and the bore of the auxiliary barrel'througho'ut its length is suitably rilled and is of a diameter to properiy receive a bullet of small caliber-as, for example, caliber 22. The auxiliary barrel ii is provided with a flange 22 at its rear end, and the said rear end portion at the flange tion 26 at one end of the body, the upright section 26 terminating in" a finger 27adapt'ed to enter the slot 24 at the rear of the barrel and engage with the forward face of the rim of a cartridge.4
To accommodate the attachment to the requirements of a revolver of the type shown, the hammer A is substituted fertile ordinary hammer, or the said hammer A may-be actually the hammer of the revolver, as said hammer A can be used upon any weapon to as great advantage as the ordinary hammer; but in eitherevent the cylinder and ejector are removed from the revolver and the new After this has been accomplished the cylinlder is again placed in position inthe body.
The auxiliary barrel B is now pushed into the cylinder and through the main barrel E, the
. slet 24: at the rear of the auxiliary barrel facl hammer A is one that is provided with a re-v cess 10 and channel 11 the firing-pin 12 is tit-` or in direction of the center of The ejector is then cocked and ing downward the cylinder.
is permitted to spring into the said slot 2t in` .tberim of the auxiliary barrel. The flange 22' of the said auxiliary barrel will be thu's closeagainst the ,rear end of the main barrel, and in order to hold the auxiliary barrel firmly in place a nut 28 is screwed upon the outer end b of the auxiliary barrel, which end is reduced and exteriorly threaded, and if the ted into the said hammer. When these changes and additions have been made to a revolver, for example, a person may practice with a revolver of the desired weight, and at the same time a small-caliber cartridge only need be used in such Work. The loading is very rapidly accomplished, since the cartridge is placed directly in the auxiliary barrel from the rear, and as the barrel is continuous the Weapon must of necessity lire straight.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A caliber-reducing attachment for [irearms comprising an auxiliary barrel having a body-section adapted to fit within the main barrel and a rear section adapted to fit within -a chamber of the cylinder carried by the weapon, the said auxiliary barrel being pro vided with an opening at its rear end for the admission of the ejecting-n ger of an ejector, Y
