KINEMATOGRAPH APPARATUS.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed September 23, 1907. Serial N 0. 394,211.

To all whom it may concern:

Be it known that 1, ROBERT ARTHUii FAU- coNNnna citizen of the French Republic, residing at 36 Rue de Menihnontant,-Paris, in the Department of Seine, France, have invented a certain new and useful Improvement in Kinematograph Apparatus, of which the following is a specification.

This invention relates to an improved kinematograph apparatus for taking living pictures and continuous projection thereof by the aid of photographic plates. The ordinary kinematographs by which pictures can be taken, and subsequently reproduced by the aid of plates arranged in series have various practical drawbacks. The pressure of the spring upon the series of plates is unequally distributed, and the first plates being held too tightly can only descend irregularly, so that the order of the succes sionof the pictures is sometimes inverted and a defective result obtained, which is still worse whenthe apparatus is used for the taking of the pictures because then forms the object of the present application for Letters Patenthas been devised. It is composed of a carrying box in which there is arranged a series of endless screws causing the regular movement of the plates, the descent of which is effected independently of one another by means of a system of propelling fingers combined on the one hand with bufiers and on the other with levers, of which one is common. and the others provided each with a catch engaging in a spur wheel controlling gear wheels engaging with other gearwheels, which keyed upon the said endless 'screws are themselves in engagement with intermediate gearing; the

shaking of the transportin box being altogether avoided by means of a system of endless band's adapted to receive each plate after its fall, and to carry it into a container arranged in the form of a bellows, so as to occupy less space when the apparatus is at rest.

A construction of the invention is illustrated in the accompanying drawing.

Figure 1 shows an elevation and partial section, the front of the box being supposed to be removed. Fig. 2 is a partial plan view of Fig. 1. Fig. 3 is a transverse view of Fig. 1 partially in section. Figs. 4 and 5 show on a larger scale the detaining mechanism of the plate while changing its position. Figs. 6 and 7 illustrate in detail the mounting of the obturators. Fig. 8 shows a plate in its holder with side racks, said plate provided with 12 horizontal rows of images totaling 144 in all. Fig. 9 shows a horigpntal section of Fig. 8 on the line The kinematograph is composed of a rectangular box '1, on the bottom of which is fixed a framework 2, preferably of light metal, comprising two uprights 3 and 4 connected above by a cross bar 58, and at one side by another cross bar 5. The upright 3 has several projections, of which one marked 6 is devised to support one end of the axle of the toothed driving wheel 7, the other end of this axle being supported by the part 8 engaged in the panel 9 of the 'box 1. A fly wheel 10 turned by hand or by means of a pulley actuated by a motor, is keyed upon the other end of thisaxle. The wheel 7 drives a pinion 11 in one piece with another gear wheel 12 keyed upon an axle supported at one end by a bearing 13 on the upright 3 and at the other end by a projection 14: attached to the panel 9. The wheel 12 drives a pinion l5 keyed upon a shaft 16 supported at one end by the part 17 fixed upon the panel 9, at the middle by the projection 18 from the upright 3, and at the other end by the projection 19 on the crossbar 5. Upon the shaft 16 are moreover keyed two toothed cone wheels 20 and 21. The wheel 20 drives a conical pinion 22 keyed upon the end of a vertical shaft 23 supported in a bearing 24 on the upright 8 and having at its lower extremity a spur 31 whichv can engage and cause to turn by one tooth.a gear wheel 32 keyed to the upper end of a shaft 33 supported by two bearings 25 and 26 on the upright 3.

Upon the lower end of the shaft 33'there keyed a conical toothed pinion 34 cont the shaft 37; this shaft is supported at one trolling two toothed plates 35, 36, loose upon attached to the bottom of the box 1.

Upon the rod 40 are keyed two rings 43, 44 arranged to serve as stops to a catch 45 secured to a transpprter box 46. This box is provided at its lower part with a rack 47 and with two pairs. of wheels 48 and 49 revolving upon the rails 50 and 51 secured upon the bottom of the box '1. Upon the shaft 37 there-is also keyed a conical toothed pinion 52 meshing with a pinion 53 keyed upon an axle 29 revolving in a'support 55 and in one piece with a toothed pinion 54 engaging with the rack 47. The transporter box 46 is guided at its. upper part by two pairs of wheels 56 revolv ng under the rails 57 secured to the top 58 of the box 1. g

-The box 46 is provided with two endless screws 59. placed in its upper part and with two endless screws 60 placed in the lower part of the upper part of this box. These screws 59 and (30 are provided at one end respectively with pinions 61 and 62 engaging with the gear Wheels 63 and 64 which engage together. Upon each screw 60 is moreover keyed a pinion 92 or 86 respcct'ively which engages with a corresponding pinion 65 or 87 in one piece with a ratchet wheel 66 or 90. I

- -Upon each axle 67 of the pinions 65 and 87 there is mounted a lever 68 or 88 each of whichpossesses a catch 69 or 89 engaging with the ratchet 66 or 90 and is articulated to one end of a bar 70 or 91, each of said bars forming a link, and being pivoted at its other end to the end of a lever 71, pivoted upon the front face of the upper part of the box 46. Each axle 67 also bears a toothed pinion 93 or 94 engaging respectively with racks 95 so held at each side by the plates 80 that the last teeth of said racks are level with the upper and lower edges of the plates. The screws 72 supported on the bracket 73 attached to the box 46 serves to regulate the motion of the lever 71, which lever is constantly drawn towards its original position by means of the spring 74. The levers 70, 91 are respectively fitted in face of two buffers 75, 76 each placed in one of the uprights 3 and 4 and so arranged that they can be adjusted by means of screws and nuts. In the lower part of the apparatus which is larger than the box- 46, there is placed the endless band 77 mounted upon two rollers 78, the axlesof which are supported in bearings 79 screwed into theIlat'- eral walls of the box 46. This endless band is devised to receive the photographic plates 80 after their fall from the upper part of the box 46 and to transport them into the compartment 81- constructed in bellows shape and placed in the lower part of the box 1.

' Upon the shaft 27 actuated by the pinion 27 is keyed the disk 82, and upon the tubular shaft 28 actuated by the pinion 28 is keyed a similar disk 82 the disks each having a perforation corresponding tov the tube of an objective 83 arranged in front of a concentration lens 84 placed in an aperture of the front wall of the box 1. The upper front wall of the box 46 possesses a slot 96 which admits of it sliding upon the end of the objective 83, the said end possessing a square opening corresponding to the s ze of the images which are to be presented n superposed rows upon the plates 80, so that the order of the succession of the images of one row will be inverted in the row placed immediately above it. centrated by the lens 84. traverse each successive image of the plates 80 and are projectedv by a lens 85 arranged in'the rear wall of the box 1 upon a support not represented in the drawing. 4 1

The photographic plates 80 are introduced according totheir serial order between the threads of the endless screws 59, 60 through a suitable opening 86-made in thepartition 58 and the upper wall of the box 1. Upon the actuation of the wheel 10 the wheel 7 engaging with the pinion 11 causes the wheel 12 to revolve. This 'turns' the pinion 15 keyed upon the axle 16, and consequently The light rays con-' turns the pinion 20 which turns the pinion with apertures, the coincidence or obscuration of which causes the intermittent display and concealment of the projection on the screen in the usual manner.

The pinion -22 at each rotation causes the toothed wheel 32 to turn by the amount of one tooth, and consequently the pinion 34 revolving the pinions'35, 36 and 52 as well as the pinion 54 in one piece with thepinion 53 causes the transporting box 46 to IDOVG forward, which box at the beginning should be placed in the end .position, so that the first image to be reproduced may be in. line with tleobje'ctive. 'VVhile the transporting box is being moved along all its length, the rotation of the endless screws 59 and 60 causes the first plate 80 to advance'by one step. This plate has been previously arranged in the second thread' of the screw, so that at the moment When the lever 91 engages for the first time'against the buffer 75 engagement withtheracks of the plates 80.

At this moment the lever 4:5 in consequence,

of its engagement against the ring 43 engages the clutch 38 in the plate 35, whereupon the rotation of the shaft 37 is reversedand the rack -17 consequently moves the transporting box in the other direction. During this second operation the first plate 80 is moved forward by another step and at the end of this operation it falls and presents its first image in face of the objective 83, at the same time as the racks of this plate put their first lower tooth in engagement with the pinions 93 and 94, which are simultaneously actuated, the one 93 by means of the ratchet 66 operated by the catch 69 engaged by the lever 68 and the lever 70 pushed back by the buffer 76; and the other 9-1- operated by the ratchet 90 actuated by the catch 89 under the influence of the lever 88, lever 91 and the lever 71 actuated by the lever 70. v

The rays proceeding from a source of light placed in front of the lens 84 pass through it and through the first image of the plate which they project upon a screen placed at a suitable distance from the lens the images will therefore be successively thrown upon the screen and at the moment of each displacement of one of them (amounting to about one-eighteenth of a second) the obtui'ator will conceal this displacement.

When the last image of a plate has passed before the objective, the second plate is substituted for the first, so that not only an entire series of plates contained between the screws can be shown, but it may even be increased by the facility given by means of the ap-' paratus to provide new plates succeeding to the first series without interruption of the action of the apparatus. i

The interchange of the plates is effected continuously without jerks; the replacement of one plate by another which is superposed upon it takes place in the same manner; the shocks produced by the striking of the levers 70 and 91 against their respective buffers 75,. 76 are deadened by the spring 74, and the fall of the plates is itself deadened by the endless band 77 which moves the plates one after the other and without jerks into the bellows compartment, so that he images reproduced are quite sharp and are only concealed during an infinitely short period at the moment of their replacement.
