There exists a number of well known apparatuses which afiord means for executing a number of successive photographs, chiefly for identity cards, on a strip of reversible paper or film, said strip being cut as soon as the desired number of photographs is obtained; the impressed strip section is treated in a series of developing, reversing and washing baths, after which it is dried and ejected from the apparatus. Such apparatuses, which are set operating by a coin and which also produce the automatic lighting and extinction of the lamps illuminating the subject, require special water and electricity supply means and can be used therefore only in those places Where a considerable supply of water and electricity is available.

The present invention has for its object a much simpler apparatus adapted for use anywhere without restriction, while affording services similar to those afiorded by any prior apparatus, My improved apparatus comprises chiefly a paper holder, hand-operated means for intermittently driving the unimpressed paper strip, an automatically operating cutting system, a view taking device the object-glass of which is automatically uncovered by the hand-operated means for driving the impressed paper strip and a receiver box collecting the strip sections so as to allow their transportation towards the laboratory where their treatment is proceeded with.

It is thus apparent that it has been possible in particular to separate the treatment of the strip from the view taking, to do away wtih all special illuminating means and thereby to considerably simplify the apparatus which may be used by any photographer in his studio.

It has been noticed that there is a risk of disturbing the proper operation of the apparatus if the means for driving the unimpressed film or strip is actuated without the prior passage of the precedently exposed and cut strip element, said passage bein performed by the above mentioned means for driving the exposed strip or film.

To remove this drawback in accordance with my invention, there is provided a locking device which is set working automatically as soon as the means for driving the unimpressed film has caused said film to advance through the amount corresponding to the number of pictures for which the apparatus is designed; this locking device ceases being operative and consequently the means for driving the unimpressed film are released only when the means for driving the exposed film have been operated.

' As far as the driving of the exposed film is concerned, it has been noticed also that the friction of the rubber-lined driving rollers of the means driving said film is not always sufiicient for producing the correct passage of the cut section of the film into the receiver. For this reason, there is provided, in accordance with my invention, a film-pushing arrangement acting positively on the upper edge of the film as soon as the latter has passed beyond the rubber-lined driving rollers in order to accompany same as it advances up to its entrance into the receiver. This film-pushing arrangement may be constituted for instance by a series of vertical rods provided with a pusher and the lowering of which with a view to accompanying the displacement of the film element is produced by a cam arranged, together with a cam adapted to move the rubberlined rollers towards one another, on a wheel the rotation of which. is produced by the means for driving the exposed film.

I will describe hereinafter, with reference to accompanying drawings, two forms of execution chosen by way of example of an apparatus executed in accordance with my invention.

Fig. 1 is an outer diagrammatical side View of said apparatus,

Fig. 2 shows diagrammatically at a larger scale the path followed by the strip or film,

Fig. 3 shows diagrammatically the association of the control means for the cutter with the control means for the movable roller of the driving means for the exposed strip or film,

Fig. 4 is a side view of a part of the mechanism of the apparatus after removal of the protecting hood,

Figs. 5 and 6 are detail views showing certain parts of Fig. 4 at different stages of the cycle of operation,

Fig. '7 is a rear view of the apparatus,

Fig. 8 is a diagrammatic side view of the means for driving the exposed film.

Returning to Fig. 1, the whole apparatus is carried by a base i which may for instance be carried by rollers and it includes means for anchoring it so as to ensure its stability. It comprises the holder 3 which is, of course, removable. The drive of the paper strip or film is produced by rubber cams 8 acting on either side of the strip or film and showing depressed portions which ensure the intermittent character of the drive. When these depressed parts face one another, the strip ceases being driven, as required for view taking. The cams 8 are keyed to the spindles carrying the pinions 9 (Fig. 1) meshing with one another, one of said pinions 9 being provided with a pawl and ratchet system coupled with a crank II allowing the hand-controlled rotation of the corresponding pinion in one direction only.

The unimpressed strip thus driven advances and passes in front of the cutter knife I2 of any suitable type and then in front of the photographic object-glass I3 the release shutter of which is controlled by a pinion I4 driven by means of a suitable transmission through one of the pinions 9. The apparatus may also comprise a ground glass I5 .and a magnifying glass for focusing, which allows taking views of subjects of various sizes. In front of the object-glassthere is preferably arranged, as known per se, a righting prism which allows the productionof 'nor mal pictures on the paper instead of inverted ones.

The exposed strip passes then between two driving rubber-lined rollers I6 and IT. The axis of the roller I6 is stationary and the roller I1 is carried by a support I:.8 --adapted to rock round an axis I9 and consequently to move nearer to or further away from the roller I5. Said roller I16 is provided with a driving crank 2I which may i be actuated by hand (Figs. 1 and 3).

After its passage betweenthe rollers I6 and I], the strip section falls into thereceiver 22 which is removable and may be made light-t ght by means of a sliding cover after the manner of a photographic frame.

I will now describe diagrammatically the association of the movements of the cutter knife with those of. the movable roller I1 -.(Eig. 3). A cam 23 is set rotating through :a. suitable transmission driven by the crank H driving one of the pinions 9, in a manner such that this cam 23 accomplishes one entire revolution for every six revolutions of the interengaging pinions 9. A lever 24 pivotally secured to the stationary pivot 5 is urged towards the surface of this cam by a spring 21 and rests against said cam with the interposition of the stud .26.. The lever 24 con.- trols the cutter knife I 2, illustrated here diagramma-tically and constituted in any known or suitable manner. The lever 24 controls moreover through the agency for instance of a slide or of a knob, a bell crank 28 pivotally secured to the stationary pivot 29. Said bell crank acts in its turn through a rod 3| on the support I8 of the roller H, the support L8 or the rod 3| bein preferably constituted by a bell crank.

The operation of the apparatus is as follows: the paper holder 3 being mounted and the front end of the strip being threaded inside the channel .7, the crank I I' is set rotating by hand. Under such. conditions, the strip advances intermittent- 1y under the action of the cams 8 and, at each stoppage of the strip, the shutter of the objectglass I3 is released whereby a view is taken.

When six photographs have been taken (the number six being chosen solely by way of example .and any other number being possible provided .a corresponding change in the ear ratio is adopted), the cam 23 allows the stud 2.6 to escape; the lever 24 rocks then from left to right,

as seen in Fig. 3, and the knife I2 cuts the strip behind the last impressed photograph. At the same time, the parts 28, 3| cause the support I8 to rock towards the left. The roller I'I moves towards the roller I6 so as to secure between said rollers I6 and I! the impressed strip the end of which is engaged between them. If the crank 2| is then hand-actuated, the impressed strip section is driven forwards and falls into the receiver 22. When the operator deems a sufiicient number of strip sections has fallen into the receiver ?.2, he closes the cover of the latter and removes same. The receiver being brought to the laboratory, the different strip sections it contains are treated in a succession of suitable baths. During this treatment, the strip sections are held by a carrier which affords means for securing them and for handling them easier.

In Figs. 4 and '7, the frame of the apparatus is shown at IIII while the holder for the unimpressed film, which is to be placed at the upper part of the apparatus, has been removed for greater simplicity in the showing. The crank 'II the axis of which is shown at I03 serves for the driving of the unimpresssed film, the release of the shutter and the cutting of the film. The crank 21 the axis of which is shown at I85 serves for driving the exposed film into the receiver. The optical system of the apparatus is shown at I3 and its picture righting prism at 2-0.

The axis I03 acts through the gear-work I08-I09 on one of the rubber cam-shaped rollers 8 the rotation of which is thus ensured in order to drive the unimpressed strip as described hereinabove. One of the wheels of the gearwork carries a pin I I I adapted to meet the lever I I2 subm-itted to a yielding pressure, ,so as to make said lever I I2 hit the bell H3 which produces an acoustic signal just .betone the shutter is released under the action of thecam H4. The axis of the gear wheel I09 which serves for the drive of the unimpressed film carries on the opposite side of the apparatus a pinion II 5 (Fig. '7) which meshes with a toothed wheel IIB. The letter carries through a smaller coaxialdisc II] a cam 23 pro! vided with .a notch IIIB cooperating with a stud 26; this stud is carried by a lever 24 pivotally secured through one end to the axis I23 mounted in the frame of the apparatus. The lever 24 is submitted to the action of the spring 21 the other end of which is secured to the casing and a. crowbar I2Ii, pivotally secured at I25 to said lever 24, is provided with a tail-piece I21 urged back by a spring I28 the other end of which is secured to the lever 24.

A long locking lever I3I is adapted to rock round a pivot I29 carried by the frame of the apparatus. The lower end of this. lever carries a projection I32 adapted to cooperate with a cam I33 keyed to the shaft I of the crank 2'I which serves for driving the exposed :film. The other end of the lever I3I may engage a hook I. pivotally secured at I35 to the frame and the tailend of which, provided with .a projection I35, is adapted to meet a stud I131 carried by the toothed wheel H6. In the medial portion of the lockinglever ISI is provided a shoulder I38 adapted to cooperate with a camv I39 having a flat radial surface and which I will term the locking cam. Said cam is carried by the axis L03 of the crank driving the unimpressed strip or film, which axis also carries in another plane parallel to that of the cam I39 a cam III with two opposite slopes adapted to cooperate with the tail end I42 of a hook I43. This hook pivotally secured at I to the frame may engage the rear portion I45 of the knife which is to be imagined as lying in a plane perpendicular to the plane of Fig. 4. This knife need not be specially described as it may be of any type and does not form part of my invention. A spring I46 urges towards the right hand side of the figure the rear end of the knife, until it against the stop I l].

The different parts have been shown in Fig. 4 in the inoperative position occupied by them as soon as the number of pictures, say six, for which the apparatus is designed, has been exposed and before the exposed film has been allowed to enter the receiver; at such a moment the locking cam I39 abuts against the shoulder I38 of the lever I3I which disengages the hook I34. On the other hand, the hook I43 keeps the rear end 35 of the knife in the position reached after the strip has been out. It is apparent that by reason of the cam I33 abutting against the shoulder I38, it is impossible to continue rotating the crank I I and consequently engaging a further length of unimpressed film into the apparatus.

If it is then desired to make the exposed film enter the receiver 22 and if the crank 2| is rotated for driving said exposed film, the cam I33 acting on the projection I32 will cause the lever I3I to rock. and to engage the hook IB B. Consequently, the locking cam I39 is disengaged and it is possible to rotate the crank I I which drives the unimpressed film, together with its axis H33. As soon as this rotation begins, the double slope cam I 4 I, meeting the projection I42, releases the hook I43 which in its turn releases the rear portion I45 of the knife which is urged back towards the stop I4'I'. Thus the knife sets the channel for the passage of the unexposed film free.

At each revolution of the axis or shaft I93, the stud III acts so as to produce a ringing of the bell H3 while a little later, the cam II 4' releases the shutter and allows a view to be taken during the time corresponding to a stopping of the unimpressed film, which progresses intermittently inside the apparatus.

As the cam 23, which performs one revolution for every six revolutions of the axis I33, rotates, it acts on the stud 26 so as to urge the lever 24 towards the right. Fig. 5 shows an intermediary position for which the end of the crow-bar I23 slides over the rear end I45 of the knife.

Fig. 6 shows the parts towards the end of the fifth revolution of the axis I513. The stud 26 occupies then its extreme position towards the right and is quite near the notch I I9. The end of the crow-bar I 25 is then in engagement with the back of the rear end I45 of the knife.

When the sixth revolution of the axis I63 begins (Fig. i), the stud I3! on the wheel I I6 meets the projection I35 and the hook I 34 releases the locking lever I 3|; but as the back of the projection on the cam I39 is then in front of the shoulders I38, said shoulder rests against this back of the projection on the cam I39 so that the axis I33 may still execute one revolution before it is stopped. During this revolution, the bell rings once and a view is taken as during each of the preceding revolutions. Then the stud 25 arriving in front of the recess H9 is suddenly urged into the bottom of said recess. The crow-bar I26 urges sharply leftwards the rear end I45 of the knife, which produces the cutting of the strip. When it has reached the left hand side of its path, the rear end I45 of the knife engages the hook I43. Lastly, the flat radial portion of the projection on the cam I39 abuts against the shoulder I38 so that the operator can no longer make the axis I03 rotate. At this moment, the parts occupy the positions shown in Fig. 4.

I will now describe (Fig. 8) the arrangement of the parts controlled by the crank 2I driving the exposed film. In this form of execution, the rollers driving the exposed film are brought together by the operation of the crank driving the exposed film instead of by the movement of the cutter knife.

To the axis I05 of the crank is secured the stationary rubber-lined driving roller IS. The same crank acts also through the pinion I52 on the toothed wheel I53 which carries a first cam I 53 which serves for bringing the rollers near one another. Said cam is adapted to cooperate with a lever I55 keyed to the axis I56 which carries on the other hand an arm I57 the end of which is provided with a movable rubber-lined roller I1. On the other hand, the toothed wheel I53 carries in a plane parallel to that of the cam I54 another cam I59 adapted to act on the stud I6I secured to the end of a lever I62 keyed to the axis I53, to said axis I 63 is also keyed a lever I54 carrying at its remote end pivoting rods I55 guided vertical to either side of the ends of the roller I5 and the lower ends of which form pusher elements I55.

When the crank 2I is caused to rotate in the direction of the arrow in Fig. 8, the projection on the lever I55 which was resting on the most projecting part of the cam I54 slides and falls on to a less projecting part of said cam, which makes the movable roller I! move nearer the stationary roller I5 so as to pinch the film I6l between said rollers; this being performed, the cam I59 engages through the stud I5I the lever I62, whereby the lever arm I54 is actuated and makes the rods I55 sink, the pusher elements I65 on the latter pressing the cut end portion of the film after the latter has passed between the roliers I5--II so as to urge said film downwards and accompanying its movement until it has entered the receiver.

When the driving mechanism is at the end of its stroke and the knob of the crank 2! is released, the axis III5 begins rotating rapidly in the direction opposed to its preceding rotation under the action of a return spring not shown and the different parts return to their starting position, as shown in Fig. 8.
