APPARATUS FOB TAKING CINEMATOGBAPHIC VIEWS.

Application illed January 26, 1928. Serial No. 815,165.

film in place and for changing it after the photographing being reduced to a minimum and of an extremely simple nature. U

This apparatus is intended for taking views having 'a short duration, andthe film which, preferably, has a reduced width and A a single central line of perforations,A consequently has a comparatively small length. It has' thus been possible to omit the winding members usually employed in the cinematographic apparatus. The film is placed in a magazine which contains an unwinding spool or holder and a winding up spool and which has two slots for the exit and re-entering of the film. Said film is directly from the unwinding spool which has a reduced inertia owing to the small dimensions of the film. It is thus possible to omit the loops or slack parts of the film which were necessary in apparatus of large size between the unwinding spool and the feeding members whereby an economy is obtained in the length of the film. The feeding operation is preferably effected Aby means of a feeding claw which has a combined horizontal and vertical movement.

As stated above, the apparatus is so con# structed that the film can -be' placed very .easily into the o erative operation and readily changed after exposure. For this purpose, the apparatus is provided with v4a loader or drawer in which one places the ma azine containing the film. Said loader is t en inserted into the apparatus and the--l construction is such that this operation,-

alone is sufiicient to have the fihn ready for operation.

Other characteristic features yof the ,in-

vention will appear from the following description.

Fig. 11 is a detail view on a larger scale corresponding to the central part of Fig. 1.

In the example of construction shown in the drawing, the apparatus comprises a metallic box 1 of a very lightconst-ruction, in the rear. part of which is engaged a loader or drawer l2 comprising a lateral wall 12, two upper and lower walls 12, a front wall 12b and a rear wall 12e. The

l.latter forms a closure for the rear end of the outer box 1, when the loader 12 has been introduced into'said box. The loader is guided in the box l by upper and lower ribs 24 (Fig. 3) provided in said box. It is `held in the box by means of a fastening device 23 of any desired type.

The loader or drawer l2 is adapted to contain a removable magazine 2 (Fig. 10) which is formed by a hermetically closed box and contains two spools or reels; an upper spool 3 which carries'the blank film and a lower spool 4 adapted to receive the The spool 4 is prowhich it is centered upon a hollow shaft i which 'is rotatably supported in the wall 12 and carries at its end a driving wheel 64. The s 0014 of the removable magazine diiven by friction by the shaft 6.

Secured `upon the inner face of the wall 12b of""the-"loadcr', is a guiding member 10 having a horizontal yslot 9 which vcoincides opening 19 with-a slot 11 in the wall 12b. The latter has also af lower similar slot 20. 'The film 7, which has a central line of perforations, comes out of the magazine 2 by aslot 8 (Fig. 10), passes through vthe slots 9, 11 and the slot 20 and enters again the magazine by the slot 21 (Fig. 10). The slots 9, 11 and 20 are opened at one end (Fig. 3) to allow for the insertion of the film; the two slots 9 and 20 are so disposed that they come respectively opposite the slots 8 and 21.

In the wall 12",- is formed an opening 13 in which is located a member 13 adapted to act as a lateral support for the film. The member 13 may be pivoted on the wall 12b at 13, asshown in Fig. 11, and lit is yieldingly forced towards the right (Figs. 1 and 11) by a vertical spring blade 14 which rests upon a horizontal rod 14 carried by the wall 12'. A vertical plate 17 is pivoted at its upper end, by the pivot 16, upon the member 13. It is urged towards the right by a spring blade 18 secured at its upper end in the member 13. The blade 17 carries a small stud 19 which extends through an in the member 13 and may engage into one of the perforations of the film, so as to hold the same stationary, during the exposure.

A perforating device 25, Fig. 1,V operated by a knob, admits of punching the blank film at the time when it travels in the guide 10, before leaving 'the loader. This mark serves to indicate the -moment 'when the taking of views is completed for a given subject.

The loader 12 can be easily removed from the box 1 so as to permit replacing the magazine box 2, when all the iilm has been used.

The feeding mechanism for the film ani the voptical elements are carried by a front vertical plate 26 which closes the front end of the outer box 1 and by a rear vertical plate 27. Said plates 26 and 27 are connected by upper and lower bracing members 28. y

The late 27 which is at a very short distance rom the wall' 12b of the loader 12, comprises a vertical guide member 29, (Fig. 4) in which the film travels. An opening 30 lis formed in the plate 27 and the guide 29; its demensions are those of the corresponding photographs taken on the film. At the lower part of this opening is provided a small notch 31 disposed opposite the small stud 19, carried by the plate 17. As. above stated, the stud 9 enters the perforation disposed between two views, so as to hold the lank film when it is exposed to the light passing through the window 30. Openings 32, (Figs. 2 and 4) formed in the guide 29` and the plate 27' engage centering studs 33 secured to the vertical wall 12b and serve to exactly centre the loader in position with respect to the wall 27, so that the .film can travel exactly in the guide 29.

The vertical slots of equal length are also provided in the guide 29 and in the plate 27. The central slot 34 (Fig. 4) gives passage to the feeding claw 34 which engages into the perforations of the film (Figs. 7 and 8) for feeding the latter. The lateral slots 35 give passage to two studs 36 which bear against the lateral parts of the film and facilitate its entraining.

The clawl 34 and studs 36 are secured to the upper part of a claw carrier 37 having a horseshoe form, pivoted at 38 at the bottom (Fig. 8) to a sliding frame 39 which is slidable in guides 40 secured to the plate 27. This frame vhas a central opening 41 with -horizontal flanges 42 between which a triangular cam 43 is adapted to work, said cam being mounted on a shaft 44 held by the two plates 26, 27.

The claw carrier 37 has at lits upper part a slotted eye member 45 engaging the edge of a cam 46 .(Fig. 9) termed f penetration cam which allows the claw carrier 37 to assume a reciprocating movement, from right to left and inversely, about thepivot 38 of the sliding frame 39. The stroke from right to left (Fig. 7) causes the claw 34 and studs 36 to extend further through the slots 34', 35 and the claw 34 is thus engaged into a perforation of the film. At the same time, the studs 36 press upon'the lateral parts of the film. The supporting member 13 of the loader 12 is provide with vertical slots corresponding to the slots 34', 35 whereby the lateral parts of the lm are yieldingly pressed' between the studs 36 and the blade 147 which is itself pushed by the spring 18. Said rearward movement of the blade 17 permits the stud 18 to be disengaged from the film. A

DuringV said movement, the sliding frame 39 actuated by the cam 43 acting on the fianges 42, moved downwardly, and hence this combined motion of the claw carrier 37 and frame 39 produces a downward motion of the film equal to the distance betweentwo perforations and between which is situated the photographed part of the film. The claw 34 and the studs 36 are then disengaged from the film by a movement to the riglit (Fig. 1).

To the shaft 44, is secured the shutter 46', comprising a semi-annular opening 47, (Fig. 6). The shaft 44 carries a worm 48 engaging a worm wheel 49 disposed on a shaft 50 to whose end is secured a pinion 51 keyed to the main driving shaft 53. To the end of the shaft 53 is screwed the control handle 54 traversing an opening 55 in the box 1. The supports 56 and 57 of the shafts 50 and 53 are secured to the plate 26.

and above the said lens the plate 2G has an opening traversed by the small lens of the finder 59. At one side of the box 1 is mounted a Wheel 6() (Fig. 4f) Whose shaft comprises a worm 61 engaging a worm wheel G2 keyed on a vertical shaft 63 actuating by any suitable means a counter of a known typei Then the loader or drawer 12 is put in place in the box 1, the Wheel 60 engages the wheel (if (Fig. 1)'. mounted on the hub 6A which actuates the' spool 4 upon which the `exposed film is Wound up.

The operation of the apparatus results clearly from the preceding description. By drawing a certain'length of film out of the magazine 2, as shown in Fig. 10, the film can be easily engaged into the slots 9 and 2() of the loader l2. The magazine is placed at the same time upon the Wall 12 of the loader and the spool et is lengaged by its recess 5 upon the shaft G. The loader1 12 is then inserted into the Ybox 1 and pushed therein. If a perforation of the film is not exactly opposite the claw 34, by simply operating the feeding mechanism this film Will come into the proper position by itself.

It is understood that the invention is not restricted tothe constructive details shown or described which have been selected only by way ofexample.
