To all whom it may concern:

Be it known that I, Rnmi ACHILLE ROBIN, a citizen of the Republic of France, and a resident of Paris, France, have invented new and useful Improvements in Kinematographic Apparatus for Taking and Projecting Views by Means of Photographic Plates, which is fully set forth in the followfront elevation of the apparatus, with the wallof the box which constitutes the dark chamber inclosing the-apparatus in section, Fig. 2 is an end view with the box in section, Fig. 3 is a horizontal section on the line 3 of Fig. 2, Fig. 4: is an enlarged detail sectional view 'of a portion of Fig. 1, Fig. 5 is'a front view of a plate showing the frame, Figs. 6, 7 and 8 are diagrammatic views showing a portion of the escapement for producing the alternations of movement and stoppage of the magazine carriage. 9 is a detail sectional view of a shutter'with two sets of exposureappert-ures for taking and projecting pictures,

- Fig. 10 is a diagrammatic view of a modification of mechanism for utilizing the force exerted by a plate passing from the vertical carrier to the receiving magazlne to cause the ejection of a plate from the distributing magazine and to cause the said plate to engage the vertical carrier, Fig. 11 is an end.

view of an'iodified form of construction.

It will be understood that the improved apparatus is designed to pro ect plctures from plates, wherein the pictures are arranged infa plurality of horizontal rows on the plate, each plate having a large number of pictures. Each plate is lifted to bring the first picture of the upper row in front of the objective, and the plate is 7 moved laterally tobring each of the pictures in the row opposite the objective insucces-' sion and with a positive stop for eachpicture of the row. The plate is again lifted to brlng the second row to the level of the objective and the movement of the plate is.

reversed, bring the pictures of the second row opposlte the objective in succession, but in the reverse direction to the movement of the plate in exposing the pictures of the first row.

The present embodiment of the invention comprises broadl namely; a distributing or supplying magazine, a receiving magazine, and a carriage for moving the plates transversely, a conveyer for moving the plates vertically, the objective for projecting the pictures, and a cylindrical cam for operating the carriage and the. conveyer.

The apparatus is inclosed in'a box a, of suitable material, and the carriage b is formed by a pair of laterally spaced cheek plates Z) and two separate and independent compartments 1) and b are arranged between the cheek plates. If is the supplying or distributing magazine for the plates to be exposed or projected,

while a compartment 6 is the receiving magazine for receiving the plates after they have been exposed. The objective e is arranged between the magazines, and at approximately the center of the front of the through which the outer end of the objective extends, as shown more particularly in Figs. 2 and 3. The plates to be exposed are passed in succession from the compartment b to the compartment b and each picture of each plate is stopped momentarily before the ob-' the following mechanisms, 7

The compartment box, the said front being closed by a plate a The cam 0 that operates the carriage is arranged in front of the carriage, and the' box fronta" is provided'with an arc-shaped extension 0.". for receiving the said: cam. The cam is operated by means of a crank 03 outside the box, and rigid with a pinion or gear wheel d inside thebox which meshes with a gear wheel d on the cam. The pinion d also meshes with a pinion i secured on the shaft 2" of the rotary shutter z. The handle (1 thus operates simultaneously the cam 0, and the rotary shutter 2'.

The carriage b is provided with a roller h, and the said roller engages ahelicoidal groove in the cam 0. The rotation of the cam 0 constrains the carriage to move laterally, in order to pass a picture before the objective, and during the moment of exposure, which coincides with the opening of the shutter, the carriage must be stopped. This stoppage is brought about by mechanism to be later described. V

Each of the plates to be shown is provided with a frame, consisting of a light plate f, of aluminum for instance, having a groove f in one edge, for receiving one edgeof the plate. The gelatined face of'the plate rests against one wall of the groove, and leaf springs f are arranged in the groove near the ends thereof, for engaging the opposits face of the plate, to press the gelatined face against the said first named wall. Each frame is provided with an aperture f, in the wall remote from the leaf spring, for engagement by one of the lugs of the conveyer device to be hereafter described. The plates, each provided with a frame 7, are introduced one after the other into the lower compartment of the distributing magazine I) of the carriage Z), 'care being taken that all of the frames f are at the same side and that the sensitized faces of the plates are turned toward the objective. The plate nearest the objective, or nearest the front of the box, is pressed against a band 6* rigi with the wall of the box, and of a Width'corresponding to the width of the frame of a plate. All of the plates in' the distributing magazine 6 are pressed rigidly against the wall of the box by means of a plate spring f", which engages that edge of the plate remote from the frame f. Throughout its entire vertical displacement, each plate is engaged by rollers if and f arranged in succession, each roller being journaled at the free end of a plate spring, in such manner that the roller 'may yield. In its vertical travel, the plate is held in the focus of the objective by its frame f, the said frame moving between the walls 6 and b (Fig. 4). 'At the side oppo site to the frame, the plate is held in the focus of the objective, that is to say against the strip or band f, by means of a roller f arranged at the level of the objective.

A bar or beam consisting of the oppositely extending arms j and j is pivoted at j upon one of the walls I) of the carriage b, and the said arms are adapted to engage the rearmost plate of each magazine. The angle of the arms 1' and j of the bar with respect to each other, depends upon the number of teeth of the ratchet wheel g.

arranged that when a plate is moved from the magazine, 6 to the magazine 6 the said arms wlll still engage the rearmost plate in each magazine, that is the arm 7' will be moved rearwardly a distance corresponding to the thickness of one plate at the same time the arm will be moved forwardly the same distance. The upper arm j"is eX- tended, as shown at j beyond the pivotal connection -7' of the arms, andthe said extension j is provided with an arc-shaped slot y'*, formed upon a circle whose center is the pivotal connection or shaft j A threaded stem on the lower arm j passes through the slot, and the said stem is engaged by a nut on the opposite side of the arm j from the arm j. It will'be evident that when the nut is loosened, the angle of the arms j j may be changed, and the said arms may be secured in adjusted position by tightening-the nut to clamp the extension to the arm j. After the plates to be exposed have been placed in the magazine 12 a single plate is placed in, the magazine If, the nut is loosened, and both arms are pressed against the rearmost plate, after which the nut is tightened to hold the arms in their adjusted position. A leaf spring 7' isarranged-at the end of the upper arm 7" for engaging the plate in the upper magazine.

The vertical conveyer for the plates is an endless chain or band g provided at spaced intervals with lugs g, the said belt or band being supported by'sprocket wheels g and 9 These sprocket wheels are keyed to shafts which are journaled in extensions from the walls 6 of the-carriage b, and the run of the chain or belt that moves the plates is guided in its vertical movement between the wall 5 and a band 6 arranged in front of the said run of the chain or band. The said band I) also prevents displacementof the lugs g from the plate. Upon the shaft of the wheel two escapement wheels are secured, and one of the said wheels 9* is arranged in the plane of the cam wheel 0. The said wheel 0 is provided with two teeth 0' and 0 arranged diametrically opposite on the periphery of the cam, and the said teeth are adapted to engage the A tooth 0 or 0 will engage a tooth of the ratchet wheel g twice during each rotation of the cam wheel 0 and will move the ratchet wheel 9 the distance'of a single tooth of the said wheel. Each of the said teeth c, 0 ends in a nose 0 which at the end of the movement of the ratchet wheel 9, that is to say at that movement at which the tooth c or c is about to move out of engagement with the tooth of the ratchet wheel, will engage the succeeding tooth of the ratchet wheel, and will stop or check the movement of the ratchet plates employed, and the said arms are so wheel at that time. The wheels '0 and g are so proportioned that the movement imparted to the wheel 'g" by a tooth or 0 will move the chain orband g a distance siiflicient to lift a plate the distance between one row of pictures and the succeeding row, On accountof the variations in height of the pltts,--it is fiecessary to provide some means that will insure that the central portion of ea'ohpic'tlire w'illbe in the focus of the objec tive. For this" reason one of the teeth G of the wheel 9" is of greater length than the remaining teeth, and this tooth is so arranged that it will be engaged by one of the teeth 0 or c at'the time when the plate is;

first'movedin front of the objective. That is, this tooth Dwill be engaged to move the chain or band when the last picture of the last row has been shown, and the first pictlire' of thefir'st row of the succeeding plate is to be brought before the objective. Since the chain or band- 9 is moved a little farther at this time, the total movement of the next plate will be slightly greater for the first row of pictures than, for any of the succeedin -rows. Each of the plates (Fig. is

- provided with a plain margin, w,- w", w' and this margin is variable as shown, The lar e tooth g' is for the purpose of moving t e chain or band a sufficient distance to compensitte for this unexposed margin. A second ratchet wheel 9 is arranged adjacent to the wheel 9" on the shaft of the said wheel 9 and a pawl in the shape of a leaf springg engages the teeth of the wheel, the said pawl acting as a retaining pawl to prevent reverse movement of the wheel gfi- Upon the shaft of the sprocket .wheel 9 two leaf springs g and g are arranged, the said springs bein ne'ar'the ends of the shaft.

I The said springs press upon the plate that slide in a sectional sleeve or bushing '2", 'andeither of the series of slots I or I opposite the objective. The seriesI is for the projectieh of pictures,--while the series I is for taking pictures. The shaft z" is mounted to the pinion z? is keyed to the shaft by a key i the said pinion being arranged between the sections of the sleeve or' bushing 5 The shaft 5 eitends outside of the case a, as shown: in Fig. 9, and' is provided with a milled head which i for convenience in manipulating the shaft and the shutter: The

shaft is else-provided with two spaced, an-.

inner grooves 2"", which are adapted to be engaged by a latch plate or stopz' connected to the case a by means ofa screw 2". When the latch 2' is moved out of engagement with the grooves i the shaft may be moved longitudinally to bring the series I or I of slots opposite the objective. The shaft may be rotated freely when the latch plate is engaged with either groove 2'".

The other mechanism for providing for the transverse displacement of the plates and for their stoppage before the objective is as follows: The escapement lever is, k is pivoted at lc vto the carriage, and each of the arms in, k of the said escapement lever is in engagement with a species of racks. The arm 70 engages the rack Z while the arm 70 engages the rack Z and the said racks are arranged alongside each other, the rack Z in the rear of the rack Z, and the arm is is offset rearwardly in order that it will engage tlie said rack, as shown more particularly in Fig. 2. The racks Z and Z- are pr0- vided with teeth, each of which is composed of two planes, one plane w which is concentric with the axis of the arm k, and upon which the end at of the arm slides inoperatively, and of a plane 3 upon the face z of the said arm a'z, the curve of the face a of the arm la-isthe resultant of the oscillation of the arm and of the displacement of the shaft k while passing for example from the position 1 in Fig.6 to the position 2 in Fig. 7, the-distance between the points 1 and 2 being equal to the displacement of the plate in front ofthe objective, that is to say being equal to the width of a picture. The racks Z and Z are oppositely arranged, that is the rack Z bears the same relation to the arm k that therack Z bears to the arm is, The faces of the teeth of the rack Z are designated by the reference characters to" and y, while the end of the arm k is designated by the reference character 01:, and the inner face-of the arm by the reference charactor a. From this arrangement, it results that when the arms is and is occupy the position of Fig. 6,- the carriage has reached the end of its movement in the direction of the arrow X, and at this moment, the roller h is engaged in the concentric portion of the groove of the cam 0. At this moment the roller and the carriage is locked from movement, by the slight engagement of the face as of the arm is upon the face w of a tooth of the rack Z (Fig. 6). Immediately that the cam c displaces the roller h in the direction indicated by the arrow Y, the roller leaves the concentric portion 0 in the cam, and the shaft k and the carriage b is displaced laterally, thearm k, k occupying the position 2 of Fig. 7. As soon as the roller it leaves the concentric portion of the cam it is displaced in the opposite direction, that is, in the direction of the arrow Y, and the arms 7;, 7c engage the faces to, w of the teeth of the ia-ClIS Z, Z These faces of the teeth are, however, concentric with the axis upon which the arms swing, and the said arms can rock without displacing the shaft and the carriage. This period of stop page corresponds to the exposure for projecting or'taking second picture, and the stoppage ceases when the arms k, in reach the position 3 of Fig. 8. At this moment, the arms 70, 7c occupy a position similar to that shown in Fig. 6, except that the carriage has been displaced by one horizontal division of the plate, and the same position, that is from position'l to position 8 are repeated, for exposing a new plate and. for again advancing the carriage. It will be noted, that the roller '7 is displaced by the cam c in a uniform and continuous manner, and that the shaft 70 and the carriage b, is locked during the oscillation of the arms, in passing from the position 2 of Fig. 7 to the position 3 of Fig. 8. The shaft 70 and the carriage 6 advance during the oscillation of the arms k, is from the position 1 of Fig. 6 to the position 2 of Fig. 8, by a length equal to the total advance of theroller h in pass ing from the position 1"of Fig. 6 to the position 3 of Fig. 8. The three corresponding positions of the arms is, k on the return of the carriage in the direction X are represented in dotted linesin Figs. 6 and 8, their action being the reverse of that shown in full line. The two ends of the groove at the point where it alters its direction are connected by concentric portions 0, and which correspond with the moments at which the plate is displaced vertically, in order to pass from one horizontal row to another. The concentric development of these portions of the groove is such that time is permitted for exposing the last rectangle of the row which is finished, time for the screening of the objective during the rise of the plate to expose the succeeding row, and time for exposing the first picture of the succeeding row.

The device operates as follows :Any desired number of plates 00 are arranged in the distributing magazine 6 each plate being connected with its frame 1. The arms j, y" are adjusted to press the plates till the magazines firmly toward the' conveyer. Should for instance it be desired to take pictures, the handle d is rotated, and the first lug 9 that presents itself in front of the base of the magazine 22 engages in the opening f of the frame f of the first plate in the magazine. The plate is lifted to bring the first row of pictures to the level of the objective, and as the said plate moves, it meets one of the small rollers f which presses it to the bottom of the frame and causes the frame to slide against the wall 6 of the carriage. The

difference in width ofthe plates will be on the opposite side from the 2 frame, and the plates will be in alinement so far as their edges are concerned at the side adjacent to the frame. The plate is then engaged by the roller f (Fig. 4) and the said roller holds the plate in the focus of the objective and assists the arm j to hold the plate firmly against the wall f while the roller 9 presses the plate laterally together with its frame against the wall I). When the plate is lifted to bring the first picture of the first row opposite the objective, the tooth c or c of the cam engages the tooth G of the ratchet Wheel g and since this tooth is slightly longer than the remaining teeth, the plate is lifted upwardly a slightly greater distance than the vertical length of a picture. This additional lift corresponds to the aggregate width of the magazines, at the top and the bottom of the plate. The carriage is displaced laterally, and stopped positively for an instant when each picture is directly opposite the objective by the cam c and the escapement mechanism, the displacement of the carriage taking place always at the movement when the objective is screened. The objective is uncovered or unscreened for exposing the plate while the carriage is stationary. \Vhen the carriage reaches the end of its lateral travel in one direction, the roller 7t engages the concentric portion 0 of the groove, and during the time that the roller is engaged with this portion of the groove, the other tooth c or 0 acts upon the ratchet wheel 9 to move the said wheel the distance of one tooth whereby to cause the plate to ascend and present a fresh row of pictures at the level of the objective, after which the carriage is displaced laterally in the opposite direction. When the first plate passes above the level of the magazine b the second plate in the said magazine is pressed forward by the arm j, the said arm 7' being actuated by the reaction of the spring 1' connected to the arm 1. The said first plate at this time is still opposite the objective, and the second plate in the magazine is pressed against the wall 6 and follows directly after the first plate. As soon as a lug g on the chain 9 enters the opening f in the frame f of the said second plate, the said .plate will be displaced vertically at the next movement of the chain. When the first plate reaches the level of the magazine 6 an inclined plane Z2 causes the upper end of the plate to enter the magazine, and at the same time the springs g and g pressing upon the frame f and the opposite edge of the plate force the said plate into the magazine, compressing the spring 9 of the arm j and causing the arm 3' to press the plates in the lower magazine toward the chain 9. It will be understood that when the plates have thus been exposed, a corresponding number of positives are made from the negatives,

cessive pictures on films or for exposing pic-- tureson films in continuous bands. In Fig. 11, a; modified form is shown for this purpose. vIn this embodiment of the invention, the distributing magazine is replaced by a reel or bobbin 1), the said bobbin or reel being mounted on the carriage b and from the reel or bobbin "v the strip passes and winds upon a reel or bobbin 0 which takes the plate of the magazine b strip or film is used, andthe ratchet wheel 9 differs from the ratchet g of Fig. 2 by the omission of the tooth- G. The film strip is moved. laterally by thecar riage b in the same manner as the plates are moved to project the successive pictures of a row and the film is moved vertically to bring the successive rows before the objective y means of'thewheels 9 g engaging the perforations of the film. In other words the a paratus is precisely thesame, except that instead of magazines for plates, reels or bobbins are provided upon which the film may be wound. The movement of the film is g and 9 the said teeth engaging the perforations of the strip, and the chain is not provided with lugs since it serves only to transmit movement of the wheel 9 to the wheel 9. I

The shaft 1} of the shutter i-may be moved longitudinally to bring either series of slots I or I opposite the objective, by means of a milled head or knob i secured to the outer end of the shaft'z", and the said shaft is pro- "vided with two longitudinally spacedannular grooves i for engagement by a lug i pivoted to the-wall of the box a by means of a screw 21*. The-shaft if is journaled' ina sleeve v7, and the pinion or gear wheel 2' is keyed to the shaft bya key or feather i.

It will be noted, from an inspection: of Figs. 1, 2 and 11, that mechanism is'provided' for absorbing the shock of the stoppage-of the carriage, when the said carriage is stopped to permit a picture to be taken or projected. Forgthis purpose a lever 76 is provided rigid with theescapement lever is k. The said lever is forked'at its lower end, and the arms 70* of the fork extend om opposite sides of a plate spring is" secured to one of,

the cheek plates 1;". The plate spring 10 is 80- arranged, that Whenever the escapement 7c is" is rocked, one of the arms of the fork will engage the plate spring, to cushion the stoppage of the carriage.
