To a whom it may concern.-
Be it known thatI, CHARLES FOUGERAT, a citizen of the French Republic, residing at Lyon, France, have invented certain new and useful Improvements in Apparatus for Permitting the Successive Exhibition of Photographs, of which the following is a specification.
The apparatus to which the invention relates allows of the successive exhibition of photographs. This result is obtained by arranging the photographs to form an unfolder, consisting of a series of photographic diapositives alternating with rigid plates of cardboard, metal, or other suitable material, so that said plates, which are retained horizontally and released by means of suitable disengaging mechanism, allow each of the photographs to be successively presented in the same vertical plane parallel to the oculars, and therefore in proper focus.
In the annexed drawings the invention is illustrated as an example applied to a stereoscope, Figure 1 being a vertical section of the complete apparatus; Fig. 2, an elevation of the photograph and plate-holding cage, and Fig. 3 a detail View showing the connection of the photographs and plates.
A is the casing containing the apparatus and adapted to be opened at the front and top. In the upper part of said casing a cage or frame B is supported, in which are arranged the plates C and photographs D, connected together by hinges or by bands of fabric, loops, or other means. The photographs are preferably placed in metal sheaths, so that they can be easily exchanged. In this case only said sheathsare connected to the intermediate plates C. The plates are cut out or notched laterally, as shown at G and G in Fig. 3, and when they havebeen folded one upon the other they are placed in the cage B and simply supported by two hooks E and F, the dimensions and distance of which correspond exactly with those of the cut-out parts Gr G of the plates. It will be understood that in connecting the plates C, as shown in Fig. 3, the notching G G is reversed in each alternate plate. Consequently when folded they will not coincide, but notching on any one plate will be laterally displaced with regard to the plate above or below. The hooks form part of slides H H, running on dovetailed tenons I 1, according to the movements to which they are subjected from the exterior by hand or automatically. For instance,
I a lever J may be used, the fulcrum of which carries a pinion K, meshing with a rack L, which is connected to or integral with the slides H H. By alternately displacing said lever in one direction and the other the hooks are caused to release the plates, and the successive fall of the latter is effected. Since it is very important that each of the photographs should come successively into the same vertical plane at the moment of vision or projection, a table M is provided on which the plates and already shown photographs are heaped. This table is not placedimmediately below the cage B, but is placed in such a way that the photograph D in the position intermediate between the cage B and the table M is held in a vertical position by that plate C, attached immediately below it, as shown by the dotted lines in Fig. 1. The table M is caused to descend progressively as the plates fall. In this manner the height of the fall is constant, whatever the number of plates already shown. For this purpose the table M is provided with two adjustable rods N N, bent at their upper ends and connected to a plate 0, which rests on the top of the pile of plates and photographs in the cage B. It will be seen that as the number of plates decreases in the cage B the table M will descend for a corresponding distance. For the purpose of guiding the last plate it is preferable to use two inclined guides P for directing said plate onto the pile on the table M.
I claim- 1. In apparatus for exhibiting photographs, the combination with a series of articulated alternate photographs and rigid plates, of a cage for holding said series, means for supporting the series therein and for releasing the plates one by one and a receiver placed with its rear wall substantially alined with the front wall of the cage so that the dropped plate holds the hotograph next above in one and the same vertical plane. substantially as described.
2. In appar atus for exhibiting photographs, the combination with a series of articulated alternate photographs and rigid plates, of a cage for holding saio series, means for supporting the series th rein and for releasing the plates one by one. receiver placed with its rear wall substantiall alined with the front wall of the cage so that the dropped plate holds the photograph next above in one and the same plane said receiver comprising a table for supporting the dropped photographs and plates in a folded condition when shown, and means for causing said table to descend according to the fall of plates from the cage, substantially as described.
3. In apparatus for exhibiting photographs, the combination With a series of articulated alternate photographs and rigid plates, of a cage adapted to contain said series, means in conjunction With said cage for supporting said plates and photographs and releasing the plates one by one to permit the photographs to drop, a receiver for the dropped plates and photographs With its rear Wall substantially alined With the front Wall of the cage so that In Witness whereof I have signed this speci-- fication in the presence of tWo Witnesses.
