E. s. PARSONS FIREARM Filed Jan. 24, 1928 his DVention -has' reference i to extension f magazi sfespecially designed for use in 'conf necti'on; ithautom'atic `firearms, the primary objec vofthe invention being to provide a sectional extension'. magazine so constructed that theaflength'f'ofthe magazine may be changedlf'with.}facility, thereby adapting the `rearmjforvarious usages. f

iaimportant. object of the inventionis tof provide meanswhereby lthe springs :in-.the magazine extensionI may rotate when Vthe positioned, jeth'ereby :'"eliininating any possi-k 1 bilityfof stretching or twistingthe springs *while the tubular sections are being rotated during the act V'of positioning them.

The sleeve 12 connects'th-ensections6 and of the extension magazine, the .sectionsfbeing shown as having their'fad] acent;endsthreaded` y,

The reference character 13 designates a magazine and at the same time provides a 14 engages. Mounted within .cap .that closes the outer end of the' extension Y. y

are the springslland lfre'spectively, the:

spring 15 being shown as having its inner end outer end resting in the capy 18,' while the'inner end thereof is secured within the cap 19'.V

These caps 18 and 19 are secured together by means of the bolt 20 that passesthrough openings formed in the caps, the connection between the caps 18 and 19 being ysuch as to permit the caps 18 and 19 to pivot with re- `resting in the cap 17, theouter end thereof A resting in the cap 18. The spring 14 hasfits spect to each other, `with the result that when v one of the sections of the extension magazine is being positioned, the springs together with their caps may rotate, thereby insuring against the springs beingdistorted to render them inoperative, while the' same are being rotated.

From the foregoing it will be obvious that should it be desired-to use the sectionf ofthe extension vmagazine,'it is only necessary 'to loosen the sleeve 12and remove 1t, 'removing the spring 14 andcaps.
