.SPECIFICATION forming part of Letters Eatent No. 582,311, dated May 11, 1897'.

Application tiled May 25, 1896. Serial No. 592,939. (No model.)

Be it known that l, AMBROTSE FRANQOIS PARNALAND, a citizen of the Republic or' France, residing at Paris, in the Republic of France, have invented certain new and useful Improvements in or Relating to fipparatus for Use in Receiving` and Projecting. Photographic Images, of which the following is a specification.

The apparatus forming the subject-matter of the present invention is destined to be used as a chromophotographic apparatus for registering or recording different movements or positions of living subjects, as well as :for the projection of such scenes, in order to give an illusion of movement.

The construction and the mode of workin g ot the apparatus will be better understood from the following description, with reference to the aecompanyin g drawings, in which- Figure l is an elevation of the whole apparatus seen from the back with the bach cover removed. Fig. 2 is a side view, 'in vertical section, on the line X Y of Fig. 1, showing the right-hand portion of said Fig. 1. Fig. 3 is an elevation of the outside ol certain parts of the apparatus at the right-hand side ol Fig. 1. Fig. 4 is a similar Viewof the parts shown at the left-hand side of Fig. 1. These views are supplemented by detail views, viz: Fig. 5, a partial view in horizontal section on the line X Y" of Fig. 1, and Fig. G a view comprising parts of the apparatus seen from a position at right angles to that from which they are viewed in Fig. 4c.

Like reference-numerals indicate like paris throughout the drawings.

The mechanism is mounted on and between two vertical side plates 10 11, parallel to each other and connected to each other by crosspieces 12, which at the same time keep them at a certain invariable distance from each other. A horizontal tube 13 is securely held in the apparatus at a suitable height, as shown in Fig. 2, being held between the two side plates 10 11. It altords at its lront endt'. e., its left-hand end as it appears in Fig. 2-a support for the photographic objective 1a and at its rear end a support for a verti cal guide 15 for the iilm 1G at the back of the objective 14.

The iilm 1G, unwound from a lixed upper spindle 17, which supports it, passes through the space 1S in Jthe guide 15, over a drivingroller 19, placed at the bottom of the apparatus, and then is wound on a lower spool 20, which is caused to rotate at a desired speed by driving mechanism, as will be hereinafter described.

The driving-roller l0 has two concentric side 'flanges 10, against which rest the corresponding edges ot' the film lb. At the back of the roller l) there is arranged another and smaller roller 21, having, like the roller 19, two concentric side flanges 22, corresponding exactly to those 19' of the said roller 19 and combining with the .latter to take the film between them and cause its movement by their rotation.

The spindle 23 of the roller 2l is held in the upper part oi supports 2t 25, which are mounted so as to be capable of oscillating on a spindle 2U, carrying two spiral springs 27 2S, the inner ends oi' which are iixed to that spindle at 20, while their opposite ends are straightened so as to press on corresponding lingers 3() $31, provided on the supports 21 25, respectively. The result of such arrangement is that the roller 2l is pressed against the roller 1) by the action of the springs 27 2S, the tension ol' which can be regulated by a handle 32, by means of which the spindle 2G can be snlliciently turned in one or the other direction to vary the tension of the springs 27 as desired, this handle 32 being then fixed in its position on a toothed pivoted catch 33, secured to the outside of the side plate 10, `Figs. 1, 4f, and 5.

One end of the roller 19 carries a toothed wheel Si, engaging with a wheel 35, carried by the corresponding side oi' the roller 2l, in such manner that the rotation of the one produces the rotation of the other in the opposite direction, and thus they cause the iilm 1G to move between their side 'flanges 19/ 22.

The roller 19 is placed under the directcontrol of a spring-drum 3C, mounted on the end oi' the spindle 37 of the said roller outside the side plate 1l. rlhe toothed wheel 3S of this drum .3G is geared to a toothed wheel Si), keyed on the main driving-shaft i0, revolving horizontally and supported on one side on the IOO outer face of the side plate 11 and on the other side in a secondary side plate 41, connected by stays 41 to the plate 11, this shaft 40 passing through a boss 42 in the plate 41 and ending in a square portion 43, receiving the handle or other part for controlling the apparatus.

The end of the spindle 37 of the roller 19 opposite to the drum 36 passes outside the plate 10 an d carries a ratchet-gear constitu ted by two disks 44 45, exactly alike and having each on theirperiphery three teeth 46 at equal intervals, both disks being secured on the spindle 37 in such a manner as to bring the teet-h 46 of one disk midway into the intervals of the other. In combination with the disks 44 45 and their teeth 46 work, respectively,two vertical rods 47 4S, held and guided vertically in a common slide 49, the lower ends of these rods forming stops for these disks 44 45 while their upper ends are hinged to the corresponding ends of bell-crank pawls 50 51, oscillating around a pivot 52 and acted upon by corresponding cams 53 54, secured at the end of a spindle 55, driven, as will be hereinafter described, by the driving mechanism of the motor. V

The combination of the latter parts of the apparatusis such that the cams 53 54, mounted on the spindle 55, so as to project in opposite directions to each other, act, in consequence of the rotation of this spindle, successivel y and alternately on their corresponding pawls 50 5l, so as to cause successive and alternate raising of the rods 47 4S, the lower ends of which release successively and alternately the disks 44 45 by releasing their teeth 46, so that these disks can turn under the action of the spring-drum 36, acting on their spindle 37. Under such circumstances, if the rod 4S, for instance, is raised and releases its disk 45, it will enable the spindle 37 to turn, which rotation will stop as soon as the rod 47, which at the start was not against a tooth of its disk 44is met by the tooth 46 of the latter, which comes immediately after the tooth 46 of the disk 45 which hasjust been released. The springs 56 57 are arranged and combined, respectively, with rods 47 4S and their common slide 49, so as to always hold the lower ends ot these rods in contact with the periphery of the disks 44 45 when they are not raised by the action previously explained of the cams In theapparatus illustrated, with the given arrangement and combination of the disks 44 45, having together six teeth 46--that is to say, three each-the rotation of the spindle 37, and consequently oi' the driving-roller 19, is eitected to the extent of a sixth of a revolution and causes, therefore, successive movements'ot" the film, each of these movements corresponding exactly to placing in front of the objective of the portion of the said film carrying the image or on which the photographic image is to be produced.

At its end opposite to the lingers 53 54 the shaft has keyed on it between the two plates 11 41 a cam 53 in one piece with a toothed wheel 59, by which latter the movement of the shaft 55 is ei'lected, the said cam causing, by means of intermediary articulated links 60 61, the alternate transversal movements of a closing` shutter 62, supported on a spindle 63, arranged over and'parallel to the tube 13 and held so that it can oscillate in its transversal supports 64 65, secured on and between the plates 10 and 11.

The tube 13, as well as the plates 10 and 11, are provided with slots, a slot 66 (for the tube 13) and slots 67 63 (foi-the plates 10 11) permitting free working of the shutter 62, which has near its outer edge an opening 69, the dimensions and the position of which are such as to correspond, as desired, to the opening in the objective. This opening 69, the purpose of which is to open the objective relatively to the illm moving at the back o1' the objective, is combined with non-peri'orated parts 70 71, causing successive closing of the objective relatively to the film alternately with opening the iilni to the objective by the opening 69. The groove oi' the cam 5S is so disposed that when the opening 69 passes before the objective it corresponds to the position of absolute rest of the iilm, whereas the passage of each full part 70 71 oi' the shutter across the objective corresponds exactly to the movements of the film, and consequently to the working ot' the parts causing that movement.

The toothed wheel 59 is driven by another toothed wheel 72, keyed on the d living-shalt 40, which carries also the wheel 39, driving the wheel 3S of the spring-drum The wheel 72 drives, moreover, by means of pinions 73, 74, (carried by a shaft 73,) and 75, the toothed wheel 76 oi' the spindle 77 ot' the winding-spool 20.

The space 1S in the guide 15, in which the film 16 travels, is form ed by a rectangular vertical opening in the said guide 15, Fig. 5, with which is combined a back plate 79, supported bylugs 8O and pressed by a transverse springblade S1, forming a latch. Screws 82 pass through lugs SO and rest with their inner ends on the bottom of the guide 15. They permit an absolutely exact adjustment of the pressure of the plate 79 on the film, in order to hold it absolutely exact, which is aided by the continuation S301? the guide 15 in between the rollers 19 and 21.

In order to prevent any sliding of the film and to secure an absolutely exact movement of it by the action oi the parts controlling it, the said iilm is provided at the edges with punched tabs and corresponding recesses 34 at equal heights on both sides. Recesscs S5 and projections S6, Fig. 5, are formed on the ilanges 19 and 22 of the rollers 19 21. These recesses and projections S5 S6 are arranged in opposite directions-that is to say,

the flange 19' on one side of the roller 19 has projections So, to which correspond recesses on the flange 22 of the roller 2l, whereas the other flange 19l of the roller 19 has the recesses 85, to which correspond projections 86 on the other flange 22 of the roller21. Moreover7 the iilln 16 is provided along its longitudinal axis with holes S7 equidistant from each other, the distance between them being exactly equal to the amount of successive advances of the film. These holes 87, provided with eyelets SS, which strengthen the edges of the holes, and thus prevent damaging of the film, cooperate with the points S9 of radial pins 90, arranged on the roller 19. These points enter successively the holes S7, whereby the film 1G is maintained in proper position while traveling, the above-mentioned impressions or tabs Se cooperating for a like purpose with the recesses S5 and projections SG of the flanges 19 22 of the rollers 19 21.

By inverting the position of the impressions 84E on the sides of the film edges it is possible, given an equally inverted arrangement of the projections and recesses S5 So on the flanges 19 22 of the rollers 19 2l to present either' face of the film lo to the back of the objective which is necessary if it is desired to use the apparatus both as a chromophotographic apparatus and as an apparatus for projecting the scenes registered by it chromophotographically.

For the chromophotographic operations the back pressure-plate 79 is without openings, whereas for optical projecting operations this plate is provided with an opening corresponding to the opening 91 in the front plate of the guide 15 and permitting the passage of the rays of light from the source of light thus projecting the pictures from the film. IThe apparatus comprises, therefore, two plates, which can be exchanged, one not perforated and the other with an opening, thus enabling the apparatus to be used for either of the beforementioned purposes.

The plate 10 is provided with holes 92 9.5, enabling the rolls of film to be put in. Covers 94 with handles cover these openings.

The whole mechanism thus arranged and mounted on the main plates 10 and 11 is inclosedin a casin g of special shape, from which it can be easily removed. This casing has in front acircular hole for the passage of the tube of the objective and at the back a movable cover with a circular opening 95, which is covered by a cover 97 for chroinophotographic operations, but which, on the contrary, is left open for the proj ection operati ons in order to allow the passage of the rays of the luminous source from behind the apparatus. rlhe casing carries besides a socket 99 for supporting a coupling for the square portion of the driving-shaft, which socket has a spindle in it with an exterior square 100, on which the action for causing working of the apparatus is exercised by means of a crankhandle or any other suitable device. The

top of the casing is besides provided with sliding support 101 for receiving the usual prism or other sighting device in order to secure proper setting of the apparatus.

The construction of the apparatus being now explained it is easy to understand its working.

The film 1G being placed in it as shown in Fig. 2, the spring of the drum 3G is wound upto `a desired extent. It is sufficient for this purpose to raise both the stops e7 4S, so as to allow the disks et -i5 to rotate and to turn the spindle 37 till the desired tension of the spring in the drum is obtained. rlhen the stops 17 -flo are released and return to their working position on the disks est 45, one tooth Ll-o of which is stopped bya corresponding stop, whereby the action of the springdrum 9o and therefore the rotation of the spindle 37 are jnevented, the result of which will secure the immobility for the time being of the film 1o'. rlhen the pressure of the roller 21 on the roller 19 is regulated by adjusting the tension of the springs 27 2S by means of the handle 32, which is secured in its position on the rack 33 with a spring, as aforesaid. It is sufficient now to turn the driving-shaft -lO in order to make the apparatus work. rlhe rotation of the shaft it) will cause, by the aid of the parts operatively connected to it, the combination of which has been mentioned previously, the alternate raising and lowering of the rods 47 iS, and consequently corresponding disengaging of the disks i 45, the result of which, in consequence of the action of the spring-drum 3o, will be the successive rotating and stopping of the rollers 19 2l, and consequently the advance in the desired direction and successive stoppages of the film 1o behind the objective. lt is important to point out here that the continuous rotation of the driving-shaft l0 causes an equally continuous movement of the spring-drum in the direction necessary to the winding up of the spring within it, and the relation between these rotations is such that the partial winding up produced will correspond exactly to the amount of unwinding by the disks -l-l: 45 and stops 4:7 t8 causing the rollers 19 21 to act. Thus the tension of the spring in the drum 3o always remains the same, and also, therefore, the impulse given by that spring to the spindle 37, so that there naturally follows an absolutely normal and uniform working of the parts, causing a uniform and regular advance of the film 1o, whatever the length of time of working of the apparatus, at any given moment. All these parts cooperating, as has been previously described, with the shutter (S2, the result is that recording` or projecting of the photographic images will be effected when the objective is opened, and when this occurs the film 1G stops, whereas closing of the opening by the shutter corresponds to the advance ol' the said film.

The speed of the a-lpparatus being suitably IOS regulated the successive advancing and stopping of the iilm IG will be effected, so that all the movements of any desired scenes can be recorded and projected in a manner which gives a complete illusion of movement.
