TUCKER, a subject of the Kingdom of Great Figure 2 is a transverse section taken on Britain, residing at Littlehaye, Bulstrode line a a of Figure 1.
Way, Gerrads Cross, in the coun y of Buck- In a convenient embodiment of the presinghamshire, England, has invented an ent invention the adaptor sleeve or tube 1 pr v d M68118 DeViC6 -P t; is provided at its foremost extremity with Spor ing n r i Small Arms a flange 2 which frictionally engages or' Miniature Ammunition Practice onUse, of slides within the uniform bore 3 of the barwhich the following is a specification. e rel 4 0f the gun, This adaptor sleeve 01' The present invention has relation toan tube 1 is screw threaded and thickened toimproved means or device f r dap ng wards its rear extremity at 5 and a conical sporting guns or like small arms for mlnianut; 6 is adapted to work upon said screw ture ammunition practice or use, and has for threaded part and co-operate with the its object to enable an ordinary sporting or coned art 7 f th barrel between the carlike gun to be so adapted that same may tridge chamber 8 and the uniform bore 3. be employed for carrying out loading, arm- The rear extremity of the adaptor sleeve or 70 ing and firing prac ice at a reduced r ng tube 1 is provided with an enlarged or flared wi h a correspondingly reduced scatter or opening 9 and fiat faces 10 or like provision separation of the pellets whereby correctfor enabling the member 1 to be rotated ness of aim may be tested conveniently within the barrel by means of a suitable againstei a s io a y o a m l m female tool which engages the faces 10. In 75 ing target in the open 01' in a Small Sh order to position this adaptor sleeve or tube room or the like. A suitable moving target the conical nut is screwed or moved to the is described in my concurrent application. foremost extremity of the sleeve or tube According to the present invention an adjacent the flange 1 and the said sleeve or adapt-or sleeve or tube is adapted to be po-sitube 1 is slidingly engaged with the barrel. tioned or disposed within the barrel of the The conical nut 6 is then securely jammed gun by means of an integral flange or bear within the conical part 7 conveniently with ing part provided upon the sleeve or tube a special tool. The sleeve or tube 1 is then which bears against or contacts the bore of adjusted axially within the barrel by means the barrel and a conical or equivalent nut of the female tool by rotation of the said 85 working on a screw threaded part of the sleeve or tube in relation to the fixed conical sleeve which bears against the coned part nut 6. A strip may be provided upon the of the barrel to position the sleeve or tube female tool adaptor to contact the breech of within the said barrel. A miniature carthe barrel when the adaptor tube or sleeve tridge is carried or supported in the cartridge 1 has been screwed sufliciently far into the chamber in axial alignment with the sleeve barrel. or tube and to the rear thereof by means of a In order to form a suitable chamber for metal bouche or annulus contained within a the miniature cartridge 11 a liner or adapliner or adaptor cartridge adapted to he slid tor cartridge 12 is employed of similar diinto the cartridge chamber of the barrel. mensions to the full sized cartridge for The sleeve or tube may be adjusted axially which the barrel is constructed, said liner of the barrel by rotating same within the or adaptor cartridge 12 is provided intersaid barrel in relation to the fixed conical nally with a metal bouche or annulus 13 nut aforestated. which may be rigidly positioned within the In order that this invention may be clearly liner 12 by pressing small parts 14 into re- 100 understood and readily carried into practice, cesses in the metal bouche or annulus by reference may be had to the appended exmeans of a punch or like instrument. The planatory sheet of drawings upon which bouche or annulus 13 is also provided with Figure 1 is a longitudinal section taken a wire or other suitable spring 15 adapted through the cartridge chamber extremity to project into the miniature cartridge of the barrel of a sporting gun illustrating chamber, so as to normally bear against the miniature cartridge 11 When same is in position. VVhen the adaptor cartridge 12 and miniature cartridge 11 are in position in the breech the foremost extremity of the min iature cartridge projects into the enlarged or flared opening 9 aforementioned and the internal diameter of the cartridge 11 is preferably equal to the internal diameter of the adaptor sleeve or tube 1.
lVith the present device it will be seen that the adaptor sleeve or tube may be securely positioned in the barrel of a sporting or like gun and loading, aiming and firing practice may be carried on under the same conditions as when employing the full sized cartridges for which the gunis adapt ed. By axially adjusting the sleeve or tube llas aforestated same may be disposed or mounted in any gun so that the enlarged-or flared opening 9 always covers or engages the foremost extremity of the miniature cartridge 11. I
The miniature cartridge 11 may be centrally fired and provided with a substantially thick shell in order that it may resist the initial explosion without distortion and also admit of continuous reloading or refilling. The detonating cap, chamber and anvil 16 may be similar to those in universal use in ordinary sporting cartridges. The loading of the cartridge 11 may be varied as to powder and wadding to suit the requirement of the shooter. According to one suitable loading four grains of fine black powder, a quarter inch felt Wad, glazed paper Wad, about 300 pellets and a close fitting paper wad on top, may be employed.
In loading the gun the only deviation from ordinary manipulation is that the miniature cartridge 11 has to be first inserted into the liner or adaptor cartridge 12 but this can obviously be done before the practice commences.
WVhat I claim as my invention, and desire to secure by Letters Patent is 1- 1. An adaptor device for use in sporting guns and like small arms comprising a sleeve arranged to be positioned within the barrel of the gun and having a fixed flange at its front end arranged to engage in the plain portion of the bore of the barrel, and a frusto-conical nut threaded on the rear portio-nof the sleeve and arranged to bear against the coned part ofthe barrel to position the sleeve. 7 v V 2. In combination with an adaptor device as claimed in claim 1, an adaptorvcartridge for the reception of a sub-calibre cartridge and comprising a shell to fitin the breach chamber of the barrel, an annulus in said shell having a sub-calibre bore, and aspring in said annulus to bear against a s-u-bcalibre cartridge in the bore of said annulus.
In witness whereof I have hereunto set my hand.
