as they may have to do with the devices for supplying cartridges in position to be forced into the barrel such devices forming the subject matter of my present invention.

This my improved feeding and loading mechanism comprises a magazine tube 14 enclosed within a casing 15 mounted underneath the barrel 11. The rear end of the casing eX- tends into an opening in a support 16 secured to the underside of the barrel the opening in said support being somewhat larger than the diameter of the casing in order to permit the latter to have a lateral movement. The front end of the casing is secured to the barrel near its forward end in a manner common to firearms of this class, and the tube 142 is removably secured within the casing in 'a manner common to small caliber rifles, this arrangementof the casing 15and the'magazine tube constituting no part of my present invention except in connection withthe parts nowto be rear endof'the casing 15 saidloading tube having 'a lengthwise opening therethrough V communicating with the'openings in the tube" 14 and casing15. This loading tube is wardly :from the rear end of the shelf and as shownin Figures 2to 5 of the drawing; A

releasing opening 21 is formed in the upper side of the loading tube at its rear end through which cartridges are released for entrv into'the opening in the breech of the barren i p The loading tube is arranged to have a limited yielding movement laterally, as herein shown, a tube supporting spring 22 being secured to the'underside of the receiver and supporting at its forward front end the rear end of said loading tube, and as shown in Figures 2, 3and of the drawing. A feed plunger 23 is secured to a feed spring 24 within the magazinetube 14, said spring extending substantially to the forward end of causes thecartridge she'll to be qnickly'tipped the :rear end of the loading tube 1:7, and asfeet this purpose a. rib+32 is formed?

In the operation of the firearm thus far described, after the casing 15 has been filled with cartridges through a. lateral opening, at its front end in a mannercom'm'on to structures of this class, the magazine tube 14, which has been pulled outwardly to the forward end of the casing,'is pushed inwardly over the cartridges, the plunger 28 moving backwardly by contact with the end cartridge, thereby compressing .the spring 241 A pressure is thus'exer'ted' upon 'the line of cartridges in the magazine tubevwith' -a--result that the cartridgesw-i-ll assume-the post tion'ishow'n ineF-i-guret 2, the breech' bolt being closed.
