Specification of Letters Patent.
Patented Sept.16,1913.
To all whom it may concern: V
Be it known that we, LOUIS JosnPH EM- MANUEL COLARDEAU, of 13 Rue de Navarin,
professor at the College Rollin, and Jonas RIoHAnn, of 25 Rue Mlingue instrument maker both in the city of Paris, Republic of France, have invented an Improved Display Device, of which the following is a full, clear, and exact description. 1
This invention relates to an operating device applicable to apparatus for classifying and distributing intended for the examination of photographic views particularly stereoscopic views, inwhich the views to be examined are withdrawn one by one from a box in which they are arranged, lifted to a level with the eye pieces and brought toward them which: permits of employing short focus eye pieces.
This apparatus comprises a carriage with horizontal movement supporting the box in which the views are arranged and capable of advancing uniformly by the distance which separates two consecutive views each time the operating mechanism is such a manner that each view is brought in succession into the plane of a frame with vertical movement; this frame is intended to lift the view and engage it in a second frame with horizontal movement which causes it to approach the lenses of the stereoscopic system.
The operating device which actuatesthe parts of an apparatus such as described above is characterized broadly by the fact that the frame with vertical and the frame with horizontal movement are each actuated by a connecting rod and a crank plate which are given their movement alternately from a single operating crank. .By means of an appropriate device the two crank plates can be driven in succession by the driving crank. In the preferred embodiment of the invention the driving crank drives two rings 'rotating together and carrying on half their periphery only setsofteeth arranged at an angle of 180 to eachother and able to engage with two separate integral with the two crank plates.
The invention is illustrated but by way of example only in the accompanying drawing in which:
Figure l is a front elevation of the apparatus with the box containing it and the stereoscopic system removed. Fig. 2 is a corresponding side elevation. Fig. 3. is a acted upon in I pinions respectively side elevation on the opposite side to the foregoing. Fig. 4 is a longitudinal section. Fig. 5 is a. detail rear elevation of the frame with vertical movement. Fig. 6 is a similar view to Fig. 4 showing the operation. Fig. 7 is a side elevation of the operating mecha- .nism. Fig. 8 is a section on the line A A in Fig. 7; Figs. 9'to 13 are detail views showing the arrangement of the toothed wheels and pinions of the mechanism. Figs. 14 to 17 are detail views'showing the means for retaining the views in the frame with horizontal movement.
As shown in the drawing the views a to be examined are contained in a box 2') mounted on a carriage 0 adapted for horizontal displacement on fixed slideways 0 A rack c is fixed to this carriage and meshes with a pinion cl (Fig. 4) this pinion is keyed to a shaft al which also carries a star or Maltese cross wheel 6. This wheelcan be actuated by means of a pin f (Fig. 3) intended to engage in the notches in the wheel; this pin is carried by a spring f mounted on a crank plate 9; it passes through a recess in the plate 9, and projects toward the interior.
The bottom of the box I) is recessed in such a manner as to permit of the passage of the branches h (Figs. 1 and 4) constituting an extractor and forming part of the frame z with vertical movement; the latter is movable in slideways i (Fig. 4) it is operated by a lever 6 (Figs. 1 and 5) rotating upon a fixed shaft i and a rod 2' pivoted to the crank plate 9.
A spring 2' acting upon the lever i balances the weight of the frame 2'.
The frame, y with horizontal movement is guided by rodsj sliding in fixed supports 7' '(Fig. 2) it is controlled by arms 1' keyed to a rotary shaft j. A connecting rod is is pivoted to one of these arms and also to a crank plate Z. In each side this frame y' carries a rocking flange m (Figs. 14 to 17) normally maintained horizontal by a spring m these flanges move aside when inclines m (Fig. 6) carried by the vertical frame 6 come into contact with them.
The crank plate 9 is keyed on a shaft n at the end of which is keyed a pinion 0 (Fig. .7). The crank plate Z is rigidly connected with a pinion 0 arranged beside theforegoing. These two pinions which are independent of each other mesh respectively with two toothed wheels 20 p integral one with the other and provided with sets of pinions 0 0 1" correspond to one revolution of the wheels 79 79 It follows from this arrangement that on giving two turns to the handle 8 and consequently to the pinion 1" in .either direction (1) the two wheels p 77 make one revolution the pinion 1' meshing in succession with the teeth Q and the teeth 9 I (-2) during half a revolution made by the wheels 29 79 one of the sets of teeth q or g meshes with one of the pinions 0 0 and causes it to make a revolution and during the other half the other set of teeth 9 or g meshes with the second of the pinions 0 0 Consequently by rotating the crank s con-s tinuously the pinions .0 0 make a revolution alternately. The pinion which does not rotate is held absolutely motionless owing to the circular slots 15 presented by cheeks t (Figs. 12 and 13) integral with the pinions; j
thecircular edges of cheeks 14 carried by the wheels 29 p engage in these slots.
The operation of the apparatus is as follows: Assuming that the last plate examined has just been replaced in the box 7) and that the carriage c has advanced by the interval separating two views the parts of the apparatus will occupy the position represented in Figs. 1, 2, 3, 4 and 5; the frame i for vertical movement is depressed; the frame j for horizontal movement is brought against it; the rocking flanges m strike against the inclines m and are pressed aside as shown in Figs. 14 and 15. If the crank s be then rotated in the direction indicated by the an row 1 (Fig. 2) in the first place the vertical frame 2' is lifted. At this moment the teeth g are in mesh with the pinion 0 the wheel leaving the position represented in Figs. 7 and 10, half the set of teeth (1 come into mesh with the teeth of the pinion 0 causing the latter to effect a half revolution and during this time the pinion 0 remains motionless. The pinion 0 making a half revolution the shaft n and the plate 9 keyed upon this shaft also rotate through a half revolution. This movement of the plate 9 causes the descent of the rod i (Fig. 3, ar-
row 4) the rocking of the lever 71 (Fig. 5)
and the ascent of the frame 2'. In this up ward movement the branches of the extractor h lift a plate and cause it to participate in the movement of ascent. This plate engages in slideways 1; (Figs. 4c and 15) in the frame 9', the flanges m being pressed aside allow the plate to engage in the plate At the end of the upward movement the extremities of the inclines m come opposite the flanges m the latter spring back and assuming the position shown in Fig. 17 support the plate below. In continuing to rotate the handle 8 in the same direction the frame 7' is displaced "horizontally. This result is obtained by the meshing of the gear p with the pinion 0 which causes the plate Z to rotate in the direction indicated by the arrow 5 in Fig. 2; the rod presses the arm j in the direction indicated by the arrow 6 which displaces the frame j toward the left (Fig. 2) and brings it into the position represented in Fig. 6. In this position the view is brought closer to the eye pieces; by leaving the handle .9 atrest the view contained in the frame can be examined for any desired length of time The horizontal displacement of the frame j "is produced by a half turn of the plate l by completing the rotation of theplate the rod is displaces the frame j in the direction 7 (Fig. 6) and applies it against the frame The pivot k of the rod 70 presents a certain amount of play in such a manner that in the rotation of the crank s'when the pivot'lc occupies its two extreme positions itis situated in a'certain dead angle; the crank can then be rotated through this anglewithout displacing the frame y. then the frame 7' again comes against theframe '5 as stated above the flanges m bear against the extremities m y of the inclines of the frame z. By rotating the handle 8. still in the same direction the teeth 9 again .act upon the pinion 0, the plate 9 efiects a half revolution and the rod 71 depresses-the frame z; from the commencement ofthe movement the inclines m de press the flanges 47?; in such a manner that the plate is no longer retained in the frame j and rests upon the'branches hfthe plate descends with the frame '5 and resumes its 3 place in the box I). At the end of this movement the pin f engages in a notch in the wheel 6 and causes it to rotate to the extent of one division. The pinion cl then causes the racks and the carriage c to advance by the amount of the interval comprised between two successive views, in such a manner that by repeating the operations that have just been described the'following plate is brought in front of the eye pieces and so on in succession. p r V The novel device is very simple and strong. It presents the advantage of operating silently in both directions on rotating It is possible to commence a movement, to interrupt it, to go back and so forth without any difiiculty.
When all the views have been examined the carriage c has reached the end of its movement. The views can then be examined in reversing the direction or the carriage can be brought into its initial position by the handle 8 in one direction or the other.
disengaging it from the driving mechanism M in any convenient manner.
The arrangements described are no applicable to apparatus for examining views but also to similar devices intended for projecting them.
The arrangements indicated above are given by way of example only and the forms, dimensions and detail arrangements can vary in every case without affecting the principle of the invention.
We claim:
In a classifying and distributing apparatus for photographic views, a box in which the views are arranged, a horizontally movable carriage carrying said box, a vertically movable frame for lifting successively each view, eye pieces, a horizontally movable frame for bringing said view near the eyepieces, a connecting rod and crank plate device for each frame, pinions respectively connected with the crank plates, a system of two toothed wheels connected together and provided with teeth on one half of their periphery said pinions engaging with said first mentioned pinions, an operating crank and a pinion for simultaneously actuating the two toothed wheels.
The foregoing specification of our improved operating device for use in connection with apparatus for classifying and distributing photographic views or the like, signed by us this eighth day of July 1911.
