-MULTIPLE-BARRELED GUN.
A NT, omcE;
Application filed August 8; 1924. Serial No 730,2364;
To all whom itmag concern: Be it known that LOARL' THILO MiiNzER, citizen-of Germany, residing at Hamburg, Germany, have invented certain new and 3- usefu1*=Improvements in Multiple-Barreled.
'Guns of which the followingis a specifica- :,ti'o'n.-- I The present. invention relates to improveirnents' inunultiple -barreled guns," rifles and worked and fashioned with great difliculty. {Although- "this" disadvantage has been known for years 'no substitute method oom- Y plying with the economical andtechnical requirementshasup'to the present been" sugfg'estedqsome time ago a method of securingthe barrels tothe breech was proposed according" tdwhich-the barrels made conical on their exterior surface were fastened in 135 the similarly conically shaped integral fchamber-piece bycold'pressing. But this construction has not been successfully carried 'into'pr'actice' The reason for failure 5 Ebarrels 'tothe chamber-piece I is too weak and f is notv adapted to resist for: any length of time the pressure or "force-of the powder gases acting on the barrel in the direction of its axis. These inconveniences induced 4 J1 the'manufacturers of'such guns to abandon the method and to adopt screwing the barrels with a short thread into the'chamberpiece; But neither does this mode of connection answer the purpose, as .it does not obviate the entering of powder gases into the thread and any-corrosions of the latter "resulting therefrom. For this reason alsothis mode of connection was condemned'and replaced by another construction in which the chamber-piece'wasfsubdividedinto two 'halves and each half made in onepiece with *combinationguns'and rifles, and refers more theb'arrels" soldered thereto can only be.
, of-this methodjis that the fastening of the the barrel appertainingtheretor halves of the chamber-piece were then connected-with-each other by adovetail-joint.
Though this construction may complywith the mere technlcal requirements, it..does not however, satisfy the economical require:
ments, as the said-construction can-only be performed with great idifliculty and considerablecosts: i
The present invention consists in pressing thebarrels into" the bores' of the chamf ber-piece; but -obviates at the sametime the drawbacksof the said know-n 'icone' connec- .tion by putting onto' and over the iendscof the.- cylindrical barrels thelikewis'eicylindrical bore's of the chamber-piece or-breech until the end-facesof-thebjarrelsare flush" with 'the end or rearface of chamber-piece;
"and then establishing between the barrels and the chamber-piece a special connectionbased upon and acting by clampingpressure and friction? This connection is efl'e'c'ted' by enlarging the external diameter offthe eX- tremities of the barrels'byQswaging or widening the same. iThe integral unitary breech or chamber-piece'is furnishedwithbores-the inner diameter {of which is approximately 7 the's'ame as the externaldiameter o'f the bar; .rels in such a mannerthat evenafter-rough ening -the contacting surfaces the barrels may conveniently' bepassed into thebores of the chamber-piece and firmly and" tightly connected therewith by swaging the barrel ends within the bores by means'of a-man'drel or the like. u I
' r In he vaccompanying sheet of-'di'aiwiilgs i 1s shown by way of eXample'apractical em;
bodiment' ofthe-novel barrel connection 'of'a double barrele d gun; Fig.1 beinga cross sectional viewand' Fig. 2 anelevat'ion of the said connection. r
Similar letters of referencej'desig'gnate like i parts throughout the figures.
According touthe mode of: carrying the; invention intocpractice the breech 'b" is pro .-j
vided with theusual locking hooks 0; and
theinn'er diameter of the cylindrical bores of the unitary chamber-piece or breech 6 correspond to the external diameterof the 3 rear ends of the barrelsc in so farthat the chamber piece notwithstanding a suitable roughening given to the contacting Qfaces, may be passed without jamming onto the barrels. After the ohamber pie ce has been placed or passed onto the barrels theends of 1 the latter embraced by the chamber-piece; I
are widened or swaged in well known manner by means of a mandrel or other suitable device to such an extent that a reliable frictional connection is obtained between the barrels and the chamber-piece. The'rear end of the barrels at the'rear face of the chamber-piece may be flanged if desired or required. For taking up the flange the chamber-piece may be provided at its rear face with a suitable annular recess.
I claim 1. An improved method of 'connecting barrels of a multiple barreled gun to a unitary chamber-piece or breech, which comprises providing the breech with longitudinal bores of approximately the same diameter as that of the breech ends of the barrels, roughening the inner surface of the bores and the outer surface ofthe breech ends of the barrels, placing the barrels with the breech ends into the bores of the breech and then swaging the barrels in order to clamp them into the bores of the breech.
2. An improved method of connecting barrels of a multiple barreled gun to a unitary chamber piece or breech, which comprises providing the breechwith longitudinal bores of approximately the same diameter as that of the breech ends of the barrels, providing an annular recess in the rear face of the breech around each bore therein, roughening the inner surface of the bores and the outer surface of the breech ends of the barrels, placing the barrels with the breech ends into the bores of the breech, swaging thebarrels in order to clamp them into the bores of. the breech, and then flanging the extreme breech ends of the barrels so that the flanges fit into the respective annular recesses in the breech.
3. An improved method of connecting barrels of a multiple barreled gun to a unitary chamber-piece or breech, which comprises providing the breech with longitudinal bores of approximately the same diameter as that of the breech ends of the barrels, roughening the inner surface of the bores and the outer surface of the breech ends of the barrels, placing the barrels with the breech ends into the bores of the breech, and then pressing the breech ends of the barrels from the inside outwardly against the bores so as to effect intimate secure frictional contact between the barrels and the breech.
4. An improved method of connecting barrels of a multiple barreled gun to a unitary chamber-piece or breech, which comprises providing the breech with longitudinal bores of approximately the same diameter as that of the breech ends of the barrels, providing an annular recess in the rear face of the breech around each, bores therein corresponding to the flange on the barrels, roughening the inner surface of the bores and the outer surface of the breech ends of the barrels, placing the barrels with the breech ends into the bores of the breech, pressing the breech ends of the barrels from the inside outwardly against the bores so as to affect intimate secure frictional contact between the barrels and the breech, and then flanging the extreme breech ends of the barrels into the respective annular recesses.
5, An nnproved breech connectlon for 'multiple barreled guns, comprising a plurality of barrels and a unitary integral breech provided with longitudinal bores the .numberof which corresponds to that of the barrels and having approximately the same diameter as the breech ends of the barrels, the latter ends on the external surface and the internal surface of the bores being roughened, and the breech ends of the barrels being placed in the bores and then swaged into place.
6. An improved breech connection for .multiple barre-led guns, comprising a plurecesses.
