f '.lhis, invention relates to fire arms and Vj :aifticularly;to types known as magazine "fshot" guns,iii whichV the recoil of each sncf Av c essive shell discharge automatically causes i `ejection of the spent shell and its replace- .ment by an vunused shell or cartridge. d

Shot guns areu'sed extensively by huntersV *and Sportsmen, iii sin"leand double barrelled'types, subjectfto the disadvantage `of Y Lfrequent reloading, causing waste of time at `iriopportune or'critic'al moments.

' It is=therefore anv important object ofthe presentfinvention to provide a shotgun having a single barrel, water jacketed if def sired, provided with a magazine for fresh Q shells and having means for the instant sub'- stitution of an unused shell for that pre-V .g `fviously exploded and ejected. s VA further feature residesY in the provision of 4means to maintain continuous firing of "jthe gun so long as thetrigger be heldin fin. ingpositionand the vsupply of shellsis i 'maintained' Y- l l Another object is .tov produced-a posedv yof few and simple parts, not readi ily disarranged and capable of being dis- -i "mou ted and reassembled without diiii- "''culty. l These and otherfvaluable objects, which `"will appear hereinafter are accomplished by the novel construction .and .arrangement of i' parts describedY and. shown in thelaccompanying drawingspforming a material part 'oofthis disclosureand in which: Fig. 1 is a topllplan view ofan embodif'/inent of the invention. y

Attached to thefiontof thestock is a guard 15 into which operatively projects a portion ofa trigger 16, in a forward or safety position bya detent to thefstock within the confines-of the guard andV movable into position to prevent movement of the trigger orv release it at will. i

VThe forward h portion of `the guard coiitains an opening in which is set theuppei" endy of a downwardly extending magazine 18, open at the top and provided with inwardly curved guides 19' at. its side edges to present moderate frictional resistance to the uppermost shell inthe magazine, the shells 2O being raised by springs', not shown, within the magazine.`
