By reference to Fig. h, it will he seen, that the aimulur ournals m practically form n tiiions or fire walls lwtwcon the openings f mul the interior of the magazine, whicl servc lo prevent llama -from 0ut$ide of the Mill magazine reaching the interior thereof through the openings /i, through which latter access may be had to the reel a, so as to rotate the same, either to wind the film onto the reel or to unwind it therefrom. The reel may be turned by means of a suitable tool, not shown, but; which is adapted to enter one or more holes it in said reel. The reel a is pret'erably provided with a metal strip or lead 0, (see l ig. 3), which is secured at one end to the lmb oi the reel and is made of sullieient length to extend through an outlet in the rim f of the magazine, so that. the picture lihn ('1 may be secured to the free end of said lead or metal strip outside of the magazine, thereby avoiding the necessity ojlf removing the side or cover c for the maga- Zlllt}.

The outlet. opening in the rim of the magazine has coope 'atiug with it a nozzle or mouth piece 10, shown separately in Figs. 5 to i' inclusive, and provided with preferably a double shut-ell or valve, which may be made as shown and consists of rollers i2, lit, having lived bearings in the nozzle or mouthpiece near the opposite ends of the same, and cotiperating roll s 15, mounted in movable supports, herein shown as levers 1t 1?.

The lever 16 is pivoted intermediate its ends as at 18 and is connected by a link it) with the lever 17, which is pivoted at its end as at 20, so that both levers move together in one direction to bring the rollers 11-, 15, into engagement; with the rollers 12 12:3, under the inuuence of a spring it (see Fig. (3) and. in the opposite direction to move the rollers ll, 15, away from the rollers 12, 123, under the influence ol' thelihn b. it ie two sets of co operating rollers and their supporting levers constitute two valves or shut-oils for the passage tor the film into and out of'the magazine, the levers being in the form of plates, which are ol a width equa to that of the nozzle or mouth piece.

Normally the rollers 11, and their levers are held in their, open position shown in Fig. 7, by the tension on the film Z), which is opposed by the spring 21, so that in case the film should become ignited beyond the outer valve 14-, the spring 21 would act to simultaneously close both the outer and inner valves, as represented in Fig. (5. if by any chance, the lire caused by the ignition oi the film beyond the outer valve, should get by the latter, it would be arrested by the inner valve. The spring pressure on the valves also serves to relieve the tension on the lilm in case the unwinding reel should stop, thereby a .*oiding liability ol the. l'ilm being broken. l urthermorc the iilm is supported bv roller beariu which avoids the danger ott' scratching or otherwise injuring the film in its passage out, 01" the magazine. in Fig. t3, the valves are nrthei r closed position,- and in Fig, Z, theyare shown in the extreme'open position, and in practice, they assume posi tions between these two extremes according to the tension on the film, and it will be seen that with a mild tension, which is desired, the valves would occupy an intermediate position, and it thetension on the tilni should he suddenly increased, it will be relieved by the yielding ot' the spring 21, permitting the \alves 14;, 15 to open wider.

By reference to Fig. 7, it will he noticed, that in the closed position of the valves 14, t5, the passage through the nozzle 16 is closed, torthe inner end of the lever 17 is designed Lo make contact with one end Wall of the nozzle orinouth piece, and the inner end oil he lever to is designed to make contact with the opposite end all, and the sides or said levers are designed to make contact or substantially with. the side walls of said nozzle, The roller 12 is des gned to make contact with the end wall with which to lever 1t COililQlHlLV l, and the roller 1.3 is (esigned to engage the lever 11', so that if to lilm 7; should become ignited outside of e nozzle, the flame would he checked by c rollers 12,1el, and lever .17, and it by any chance, the tlame got by the rollers 12, it, before they make contact with each other, it would be arrested by the lever 16 and rollers 15, 13. To still further reduce the tire and explosion hazards, l prefer to etnplo an outer casing or magazine having a cover 31 suitably pivoted thereto and within which the tilm containing maga-. zine located, said outer magazine having an outlet nozzle or mouth 32 similar to the nozzle or mouth pie e 10 of the inner magazine, it being provided with an inner and outer valve (not shown). The outer magazine provided with means for positioning the inner magazine within it, so as to re duce to a minimum the length of film posed within the outer magazine. In the present instance, one form of means iior this purpose l own, which consists of two ot-lied uprights secured to the bottom or back of the outer magazine and adapted totreceive pins or projections 36 on the inner magazine, said uprights being located, so that the outlet; end or the nozzle 10 ot the inner magazine will. be located substan tially close to the inlet, end of the nozzle 39 oi the outer magazine, clearly shown in Fig. 2. The cover Ell may have secured to its inner side spring 38, which is adapted to the inner magazine when the coverx is closed and retain 'the latter in its proper position against accidental. displacement or movement.

From the above description, it will be seen that the danger of the film within its in gazinetieeoining ignited is reduced to a minimum, for when the magazine is in use in t e moving picture machine, it is proteeted by a substantially fireproof construction, as the only-means of the tire reaching the film within the magazine is safeguarded by the plurality of valves or shut-oils.

ll hen the tihn is'used in a moving picture machine, it is unwound from the reel (1 in at delivering magazine, and wound upon a reel within a receiving magazine. it trequently happens that the windingmp reel of the picture machine as now commonly constructed, fails to work properly, and in such case, the ope 'ator is obliged to expose the film in order to get access to the reel. thereby increasing the danger from tire under these conditions. This danger is avoided in the present instance, for it the winding-up reel of the picture machine equipped With the magazine herein shown, should fail to work properly, the operator can turn the reel by hand without exposing the film, owing to the fact that the reel is accessible from outside the magazine. litter the film has been wound upon the reel of the receiving magazine, it must be unwound therefrom in order that the pictures may appear in regular order. As now commonly practiced, tins is done on a ma-- chine called the rewindii'ig machine with the reels and film exposed, and usually from eight hundred to a thousand feet ot film is thus exposed. This operation of rewinding as now practiced, is attended by great chances of fire, owing to the exposed condition of the film. This danger is avoided by means of the reel-containing magazine herein shown, for when it is desired to imwind the film from the reel of one such inagazine and wind it upon another, it is unnecessary to expose the film within either or both magazines. It will thus seen, that.

in the rewinding of the film, the tire hazard is greatly reduced as but a short length of film between the magazines is exposed, and in case this should become ignited, the great len. th of film vlllllfl the magazines is safe ,e naided by the shut-oils or valves. To still further reduce the danger ignition ir. winding, I prefer to use the strip or lead 0 and secure the end of the film thereto by suitable connection or fastening device one form of which is shown in '0 and 9, but Whichmav he oiany suitable or desired. construction.
