This invention relates to improvements in film magazines for motion picture cameras, the principal object of the invention being to provide a magazine comprising twin sections having convenient carrying means and means whereb the magazine may be placed on a floor or ot er support in an upright position without damage to a film carried by the magazine.

Another object is to provide a magazine having means for centeringthe same in proper position on a camera.

A further object of the invention is generally to improve the construction of the magazine so as to increase the efliciency of the light locks at all connecting portions of the magazine. i

Other objects and advantages of the invention will appear as the description prol ceeds.

In the drawings accompanying this specitcation,

Figure 1 is a partly sectional side eleva-l tion of a magazine embodying the features i of the present invention; and

Fi ure 2 is a cross sectional view taken approximately on the line 2--2 of Figure 1.

Referring to the drawings, the magazine housing comprises twin sections 1 and 2 of ap- 80 proximately circular form, said sections constituting respectivel the supply section and the take-up section or a traveling lilm 3. E

The sections are connected in tangential relation to each other, by means of webs 4 and are also'united at what may be termed I their upper side by the merging together of their peri heral walls as shown at 5, Figure 1, from w ich merged peripheral portion clends a partition or wall 6 integral with but 4 ying in a plane at right angles to the webs 4. The sections 1 and 2 are further connected together b ahandle 7 formed integral with the perip eral walls oi? the sections, said i handle bridging or spanning the s ace between the sections at a point above t e partition 6 and forming a convenient means for lifting and carrying the magazine. Y

At the side of the ma azine opposite from the handle 7, an L-shape on the peripheral wall of each of vthe secextension is formed A CORPORATION OF vNEW YORK FILM MAeAzINE Application med september a, i929. serial No. 391,386.

tions, the verticalportions of which extensions form between them a chamber for the reception of the necessary film roller support, which in the present instance comprises a pair of duplicate blocks 9 and 10 Fi ure 2) disposed in abutting relation to` eac other and removable as a unit from said chamber. Thus the ma azine housing may be constructed in a sing e lunitary structure as by casting. f

nach of tile biockSJe and 1o is bored inwardl from its abutting face for the reception o a plurality of film guidin rollers, five such rollers 11, 12, 13, 14'and 15 ing shown mounted inthe block 9 in Figure 1. This arrangement of rollers forms an effective light lock for the film 3 during its passage from the supply section 1 to the camera and thence to the take-up section 2. In order to insure the exclusion of light from between the abutting faces of the blocks 9 and 10, each block is provided in its face with a groove of semicircular form` in cross section, so that when the vblocks are assembled a tubular opening 16, Figure 2, is. formed between them, said opening extending from side to side of the blocks for the reception of a c lindrical pin. Inasmuch, however, as the b ocks are provided with a pair of slots 17 and 18 for the passage of the film 3 into and out of the camera, and which slots intersect the vopening 16 and thus divide the lower portion of the blocks into three separate walls, as clearly indicated in-Figure 1, the pin is necessarily formed in three sections, each of suilicient length to extend throughout the thickness of the wall in which it is placed. It will thus be seen that it will be impossible for light to penetrate upward between the abutgort the magazine in upright position on a oor or other support when not in use, and assist in centering or guiding the magazine in its operative position on the camera thereby to properly position the throat of the magazine with respect to the camera. The throat-forming blocks 9, 10 are provided at their lower ends with lateral flan es 21 throu h which they may be removaly secured y means of screws 22 to the horizontal walls 8a of the L-shaped extensions of thc magazine sections, said flangesbeing adapted to lie between the undersides of said walls and the top of the camera. The blocks 9 and 10 are further provided on their bottom surfaces with a circular flange 23 lying in a plane perpendicular to the flanges 21, the

flange 23 being adapted to extend into snugtting contact with the wall of a circular opening formed in the top of the camera. This arrangement serves not only1 further to insure the proper centering of the magazine on the camera, but by reason of the anguv lar relation of the flanges 21 and 23 a lighttight joint is formed between the camera and the magazine housing. The removability of the blocks 9 and 10 with the film guiding rollers is particularly advantageous in that it permits ready access to the parts for cleanino, renewing, etc.

Xtending centrally across the undersurface of the two throat- formin blocks 9 and 10, is a strip 24, said strip being secured by screws 25, Figure 2, to that section of the wall of said blocks lying between the slots 17 and' 18 and underlying the central roller 15. The side edges of the strip are smoothly rounded off, said strip thus forming a spacer for the film 3 as it passes into the camera from the supply reel and out of the camera to the takefup reel. It will be observed that the lower surface of the strip 24 lies in a plane above that of the lower surface of the legs 19. Because of this arrangement the magazine may be placed in standing position without danger of damaging that portion of a film that may be over the strip by contact with the floor or other support." Also, when the magazine is placed in position on the camera, with the bight of the film drawn up against the strip 24, the operator may simply pull the lm downwardly therefrom, within the camera for threading.

The magazine is provided with suitable coverplates or lids for the supply and takeup sections, each of said cover plates 26 being preferably thread-connected with its section as indicated at 27, Fi re 2, and provided with a flange 28 over ying said connection thus forming an eective light lock around the top edge of the section. For facilitating removal of the cover plates and enabling them to be screwed into tight engagement with the res ective magazine sections, a plurality of radially extending ribs 29 may be formed on the outer surfaces of the cove plates. The cover plates and the o positie ends of the magazine sections are pre erably of double-walled construction, and a sound proof padding 30 interposed between said double walls, as shown in Figure 2. The reel shaft in the take-up section of course extends to the outside of the magazine housing and is provided with a crossbar 31 or other suit)- able means for receiving rotary motion in the usual manner. The chamber in which the throat-forming blocks 9 and 10 are located is provided with end- closing walls 32 and 33 respectively, see Figure 2, formed integral with the magazine ousing at the opposite ends of said housing. For preventing light entering between the sections, each of .the blocks is provided in its top side with a centrally disposed channel ada ted to engage the lower end of the depen ing wall 6 between the sections, as shown at 34, in Figure 2. Suitable locking means adapted to be op- Y erated by screws having knurled heads or flanges 35 are provided for lockin the magazine to the camera, these devices eing well known in the art.
