KINEMATOGRAPHIC APPARATUS.- I

Specification of Letters Patent.

ori inal application filed am, 1908, Serial No. 419,311. Divided and this application filed June 17, 190a. Seria1No.438,920.

To all whom it mag concern! Be it known that we, JEAN LEON MULLER and Jonas RoUss T, citizens of the Republic of France, the former residing, at Sannois o making kinematographic glass plates according to our application, Serial No. 419,311, filed March 5, 1908.. The apparatus may also be used as a projecting apparatus for use with such kinematogra hic plates after they have been made, an also as a device to directly take on one glass plate a number of views of animate objects.

With I these ends in view the invention consists in the novel features of construction and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure l is a rear-elevation, with parts removed, of the apparatus, Fig. 2 is a vertical section on line 2, 2, Fig. l, and Fig. 3 is a horizontal section on line 3, 3, Fig. 1.

The apparatus comprises a casing A in which a lass late a is so moved that a number 0 small views may be photographically reproduced, side by side, over the entire surface-of the plate, in connection with a light-opening B in the casing in which is mounted an objective u. The plate a is fixed in a frame I) capable of vertical displacement in slides 0, which form art-of an assemblage which is itself capable of displacement on the fixed'horizontal slides d. These displacements are regulated in such a manner that the different views of the lower horizontal row'of the plate first of all pass in succession in front of the objective, the plate moving in the direction indicated by the arrow 1; .at the extremity of this row the plate is depressed by the height of a view; the plate 1s then again displaced horizontally, but' in the opposite direction to the arrow 1, and all the views in the second horizontal rows pass in succession in front of the objective; at the extremity of this row the plate is again depressed and the third row of views is level with the obect ve. In this manner the plate is subjected 'to'a reciprocating horizontal movement regularly interrupted at the end of each travel by a depression corresponding to the height of a view. The movement is produced by a handlee driving a toothed pinion f which meshes with a gear-wheel g..

The gear-wheel -g carries on one of its faces, in proximity'to its periphery, a series of ribs, the uniform arrangement of which serves to produce sinuous paths 7:. in which pins 12 engage; these pins correspond 1n .number to the views in a horizontal row a manner that a complete rotation of this wheel produces a displacement of the bar 7' and consequently of the plate a, first in the direction indicated by the arrow 1 and then in the opposite direction. The bar 7' is guided in its displacements by the rollers k.

In addition to the ribs indicated, the wheel 9 is provided (at one only of the places at which the direction of the paths h changes) with a boss I acting at each semi-revolution of the said wheel, alternately upon each of the rollers m and, 11. solid with the whole constituted bythe vertical slideways c, the bar 7' and a device located behind the plate-holding frame I) and which, as will hereinafter appear, serves to su'pport the latter. arrangement comprises aplate 0 carried by the part of the system which is movable in the horizontal direction; this plate is slotted at p and q in such a manner as to form slots.

in whichla, certain number of pins 1', 'fixed on the uprights or vertical parts of the frame I), are able to en'ga e. Stops s are formed in the slots 7), g-{an 'the pins 1' enter these stops after each vertical displacement of the plate. The vertical intervalbetween' This the handle 6 be turned in the direction indicated by the arrow 3, the gear-wheel is driven in the direction indicated by the,

arrow 4. The first .pin 71 of the bar traverses the sinuous peripheral path or groove h in which it is engaged; in doing so it reaches h where the path formsan incline;

the wheel g continuing to' rotate, as will be understood; a tractive effort is produced upon the bar j and the part of the system which is horizontally displaceable moves in such a manner that the second view of the first horizontal row moves in front of the objective. At the same time the second pin ?I ,of the bar j has entered the following sinuous path; a displacement similar tothe preceding one is produced. All the'pins i come in succession in a path it; when the last pin is thusengaged-the plate has reached the limit of its travel in the direction indicated by'the arrow 1 and the wheel 9 has made a semi-revolution.

been displaced simultaneously with the plate. The effect of this encounter is the; displacement of the plate 0 relatively to the tion to that indicated by the arrow 1 and the second horizontal row of the views present themselves successively in front of the objective also in the direction opposite to that indicated by the arrow 1. When the wheel 9 has effected a complete revolution, the boss Z encounters the roller m and the plate is again. depressed. The operation is the same until all the views have passed in front of the objective in the order set forth. The shaft t which carries the gear-wheel g is hollow. When the apparatus is used for photographing on a reduced scale the images from a band of film, the tubular shaft 25 is'provided in front with a perforated diaphragm plug .2. The luminous rays then pass through the objective at and fall on the plate where theirv area is'limited by theiwindow u formed :at the extremity of the cone. c. 'When the apparatus-serves for projection, the plug a is. unscrewed and the rays of an appropriatesource of light pass through the tubular shaft, the plate,

I the Window and the projection objective in the opposite direction. The shutter 11 with four screens 4: is actuated by the toothed pinion as which meshes with another pinion y keyed upon the shaft 25 of the gear-wheel g. Thus it is automatically operated by the At this moment. the boss Z encounters the roller 0?. which hasv teases plate-moving mechanism. Finally it should be noted that the special apparatus which has just been described may be utilized, without modification, for photographing animate objects directly whenever the magnitude of the projection does not exceed the limit'at which the grain of the plate would be visible. in this case the apparatus is arranged in a light-proof asing and a very rapid special plate is replaced by a'sensitized plate.
