PICTURE-EXHIBITOR.

SPECIFICATION forming part of Letters Patent No. 582,597, dated May 11, 1897. Application filed May 18, 1896. Serial No. 591,855. No model-l To all whom it may concern.-

Be it known that 1, AUGUST BECKER, a citizen of the United States, residing in the city, county, and State of New York,have invented certain new and useful Improvements in Picture-Exhibitors, of which the following is a specification.

This invention relates to an improved picture-exhibitor for the exhibition of photographs and other pictures, advertising devices, and the like in which the pictures or other matters can be successively brought to View, while they are protected against handling, the exhibitor being operated either by hand or by a suitable power in case it is used for advertising purposes.

The invention consists of a case or receptacle in which two piles of picture-holders are arranged sidewise of each other, said holders being provided with slots in one end and re cesses in one side, the latter receiving a vertical rail of a transverse partition which separates the two piles. The slots of the pictureholders are engaged by spring-pushers, one being arranged below one pile of pictures and one above the same and supported in a suitable slide, said pushers being operated by a pivoted and spring-retracted lever-arm operated by hand or a suitable motor. The forward motion of the lever-arm moves the bottom holder from one pile to the other pile, while the return motion of the lever moves the top holder of the latter pile back over the first pile. A safety contrivance is arranged in connection with the lever-arm, so as to prevent the return of the same under influence of the spring until the entire swinging motion is completed.

In the accompanying drawings, Figure 1 is a perspective view of my improved pictureexhibitor. Fig. 2 is a vertical longitudinal section of the same on line 2 2, Fig. 1, showing the mechanism for moving the pictureholders from one side of the apparatus to the other. Fig. 3 is a vertical transverse section of the same on line 3 3, Fig. 2. Fig. 4 is a bottom View of my picture-exhibitor, showing the mechanism for shifting the pictureholders. Fig. 5 is a detail top view of one of the picture-holders. Fig. 6 is a vertical transverse section of the same on line 6 6, Fig. 5.

Fig. 7 is a detail perspective view of the grooved plate forming part of the safety appliance; and Fig. 8 is an enlarged transverse section on line 8 8, Fig. 4.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a box or receptacle of suitable size and material, which is provided with a hinged lid A, having glass-covered openings through which the pictures can be seen. The box can be supported on suitable feet applied to its bottom or one of its sides, according as the pictures are to be exhibited in horizontal or vertical position. The box Ais provided with a central transverse partition a, that extends to a certain distance from the top and bottom of thebox, so that the picture-holders can pass readily below the lower edge and over the upper edge of the partition a.

The picture-holders Care preferably made of pasteboard or other suitable material and size, so as to receive photographs of cabinet size, but they may also be made larger or smaller, according to the purpose for which the picture-exhibitor is to be used. The picture-holders C are arranged in two piles, one pile being placed in each compartment of the box A.

Each picture-holder (J has its side edges beveled in opposite direction, and is provided at one end with a slot 0 and a recess 0 in one of its beveled sides, which recess receives a vertical guide-rail a. on the partition (1, so that the pile of picture-holders at the righthand side of the partition is guided as they pass in downward direction, said rail also preventing the wedging in of the pictureholder next to the lowermost one when the latter is moved forward by the shifting mechanism. Without the rail it might frequently occur that by the friction between the picture-holders the one next above the lowermost one would be carried along, so that they would wedge in below the partition and disturb thereby the regular working of the apparatus.

To the under side of the box A is pivoted at d a lever-arm D, which is provided with a sliding extension D and a handle cl at its front end said arm being guided in the sleeve flanged slide E, which is arranged to slide in a vertical plane parallel with one side of the box and guided by its bottom flange in a bottom slot cin the bottom of the box, said slide carrying at its lower end a pusher-spring E,

that projeetsby its nose or bent-up endinto the oblong slot 0 of the lowermost pictureholder 0. The upright part of slide E is guided between a side wall of the box and a longitudinal partition a parallel therewith, asshown clearly in Fig. To the upper flange of the slide E is attached a springpusher E, which is arranged .in opposite di-- reetion to the other pusher E, so that the upper pusher E will take into theoblong slot v of the uppermost, picture-holder. The noses or bent-up ends of the spring-pushers are beveled off, so as to pass vreadily over the picture-holders during their return motion without en g'a'gi ngthe picture-holders. Thespringactuated lever-arm D is connected by a spring-arm F, which is pivoted to said leverarm D, with an elongated grooved plate F. Theend ofthe spring-arm F is madein the shape of apin f ,that engagesthe grooves f fin the grooved plate F".

During the forward motion ofthe lever-arm the pin f of thespring-arm F moves in the groove f, but returns in the other groove f duringthe return motion of the lever-arm. The

depressions Win the bottom of the groove f of plate F serve, throughthe engagement of the .pin f 0 therein,.to arrestthe lever-arm D, when the same should be released for some reason or the other during its forward motion, so as to prevent the release of the picture-holder, which was in the act of being moved over, and prevent thereby confusion and injury to the interior mechanism of the apparatus. The lever-arm D is in that case moved farther forwardfrom its point of detention, so as to fully shift the picture-holder. The grooved plate F and the spring-arm F thus form a protect- ,ing device for the actuating mechanism of the picture-exhibitor, whereby the same is prevented from getting out of order by careless or inexperienced handling of the same.

My improved picture-exhibitor is operated as follows: The pictures to be exhibited are first inserted into the picture-holders and the same placed in position .intwo piles or stacks at both sides of the central partition a, one above the other. The lever-arm is now moved fromone end of the box to the other and back again. This motion produces the shifting,by the pusher E, of the lowermost picture-holder of the right-hand pile into lowermost position below the other pile, and the top pusher, be-

ing arranged in inverse position, passes over and engages the uppermost picture-holder of the left-hand pile, which is lifted suifieiently by the additional picture-holder moved into the bottom, so that when the lever-arm is released at the end of its forward stroke it is quickly returned by. the tension of its spring and thereby the uppermost picture-holder of the left-hand pile moved by the top pusher E back over the right-hand pile. At every full oscillating motion of the lever-arm 1) this shifting operation of two picture-holders is repeated, and in this manner all the pictures in the two piles are successively exhibited. It is obvious that in place of the lever-arm and its actuating-spring a positive motion may be imparted to the lever-arm by a spring or other motor with which said lever-arm is connected by a connecting-rod, or otherwise. In this casethere would be no uncertain return movement, but a positive return motion under the action of the motor. 'When the picture-exhibitor is used for exhibiting pietures in photographic or other suchmatter, a motor is preferable, as thereby the attentionofthe public is attracted to the movable pictures in the exhibitor. In this case it may be preferable to place the box with its pictures in vertical position.

Myim proved picture-exhibitor can be used .as a photograph-album for family use or when made on a larger scale for an advertising device for exhibiting photographs or otherpictures, or, if desired, advertisingdeviees may be used in connection with the pictures. The photographs or other matter can be readily exchanged by opening the box, removing the picture-holders, inserting new pictures and replacing the picture-holders in the box, and then operatingthe actuating lever-arm in the manner described, whereby by the lever first the bottom pictures are shifted, then by the return motionof the lever the top pietures, and thereby all the pictures are successively brought to View.

I am aware that picture-exhibitors in which shiftable picture-holders are arranged and sliding mechanism for shifting the same from one side to the other are well known, and I thereforedo not claim the picture-exhibitor shown broadly.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a picture-exhibitor, the combination, with a box or receptacle having a transverse partition, two piles of picture holders arranged one at each side of said partition, a longitudinal partition parallel with one side wall of the box, a slide arranged between the longitudinal partition and said side of the box, and adapted to move parallel therewith, said slide having flanges at its upper and lower edges projecting inwardly beyond the edges of the longitudinal partition, pushers arranged on the adjacent surfaces of the flanges and adapted to engage said pictureholders, and means for actuating said slide, substantially as set forth.

2. In a picture-exhibitor, the combination with a box or receptacle having a transverse partition, recessed picture-holders arranged in piles on opposite sides of said partition, a vertical guide-rail on the partition engaging in the recesses on the picture-holders, top and bottom pushers arranged in opposite directions and adapted to engage said pictureholders, a slide supporting said pushers, and a pivoted and spring-retracted arm connected with the bottom of the slide and adapted to move the lowermost picture of the one pile under the picture-holders of the second pile, inits forward motion, and to move the uppermost picture-holder of the second pile over the picture-holders of the first pile during the return motion of the arm, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signedmyname in presence of two subscribing witnesses.

AUGUST BECKER.
