T. J. BEHYMER PICTURE PROJECTING DEVICE Filed June 8, 1933 July 10, 1934.

Patented July 10, I934 PATENT oer-"Ice UNITED STATES- Claims.

and objects represented by the separate pictures Objects of the invention are to provide an improved projecting device including a stationary reflector disposed and supportedat an angle of inclination with respect to a number of stationary or moving pictures, or a number of stationary or moving strips representing parts of complete pictures, whereby the pictures are projected with perspective, or the parts of complete pictures with perspective representing a complete picture; to provide means for supporting these pictures or parts of complete pictures and the reflector in illuminatedzones in order to heighten and enhance the artistic appearance and effect thereof when seen in the reflector; to provide improved meam for supporting parts of pictures in spaced relationship inorder to obtain the best effects of perspective; and to provide operating mechanism for moving the pictures or parts of pictures to represent scenic views, vehicles, people, or other pictures or objects. 7

Other objects will appear from the following description, reference being made to theannexed drawing, in which Fig. 1 is a front elevation, with parts in section, of my improved picture projecting device. 7

2 is a vertical front to rear sectional view approximately on the line 2-2 of Fig. 1.

Fig: 3 is an enlarged detail sectional view of a part of the mechanism for moving the pictures or the parts of pictures and permitting movement thereof in either direction.

Fig. 4 is a diagrammatic view showing the general form of the flexible mesh, openwork or transparent picture supports.

Fig. 5 is an enlarged cross sectional view of one of these picture supports on the line 5-5 of Fig. 4.

In the construction shown, the operating mechanism is contained within a cabinet or enclosure formed by front, rear and side walls 1.'

the'end edges of the walls 3 and 4, respectively.

These walls 3, 4 and 5 constitute the walls of a frame or tunnel of decreasing area toward the A downwardly and rearwardly inclined wall 5 is mounted on the cabinet and a mirror or other type of good reflector '1 is attached to the under side of the wall or support 6 beyond the rear of the frame or tunnel provided by the walls 3, 4 and 5, so that the images of objects from below this reflector 'I will be easily observable therein through said frame or tunnel.

An opening 8 is provided in the upper end 0 the cabinet below the reflector 'l and has marginal supports .9 upon ,whiclran appropriately shaped proscenium frame 10 is mounted. This frame 10 is invisible but its image is reflected by the reflector '7.

Elongated electric lamps 11 are supported in concealed position above the plane of the rear end of the upper frame wall 4 adjacent to a reflector 12 whereby: the light of said lamps is reflected downwardly against the reflector '7, upon the proscenium frame 10 and through the opening 8.

-A support 13 is mounted in the cabinet a suitable distance below the opening 8 and may be painted, or otherwise characterized, to represent the sky with or without cloud effects, or other appropriate background.

A vertical series of horizontal rollers or spools 14,15and16areattache'dtorotaryshafts17 at one end of the cabinet and a similar series of rollers are attached to horizontal rotaryshafts 18 at the opposite end of the cabinet. this series of rollers being beyond the ends of the opening 8.

A sliding beveled tooth clutch member 19 is splined on the end of each pf the shafts 17 and 18 and actuated outwardly, by a spring 20 toi clutching engagement with thebeveled pinion 21 loosely mounted on the end portion of each of said shafts 17 and 18. This construction provides a-positive drive whereby forward turning of each pinion 21 will positively rotate the corresponding shaft 17or 18 but will permit each of said shafts to be rotated in the reverse-direction by escaping action of the clutch member 19 against the pinion 21 of the specific arrangement shown, I may use endless belts showing the picture parts thereon.

A vertical shaft 22 is mounted adjacent to the ends of the shafts 1'1 and to the ends of the shafts 18, respectively, and haveattached thereto beveled pinions 23 in permanent mesh with the pinions 21 on said shafts 17 and 18, respectively. Eachshaft 22 hasattachedthereto'alarge gear 24 meshing with a small pinion 25 driven by the respective motors 26. and 2'7, the motor'26 driving the gearing for rotating the shafts 17 and the 1 .motor 27 driving the gearing for rotating the shafts 18. These motors do not run simultaneously but only run alternately, so that when the motor 26 is running the motor 2'? remains stationary, and vice versa.

The supporting frames. 28 for the shafts 17 and 18 have inwardly extended arms 29 supporting pairs of tensioning rollers 30, there'being one pair of each of said rollers 30 for each shaft 17 and also one pair of said rollers for each shaft 18.

Strips of mesh, transparent or openwork 31 have ends attached to the rollers or spools 14, 15 and 16, respectively, and their opposite ends attached to similar rollers or spools on' the shafts 18. These mesh, transparent or openwork supports 31 extend between and are tensioned by the pairs of rollers 30 and may have along their front and rear marginal edges strips 32 of inelastic material, which may be connected by transverse strips 33 of. inelastic material providing frames, as should be understood by reference to Fig. 4 of the drawing. Strips 34 containing pictures of parts of scenes or entire scenesor objects to be projected in perspective relationship with respect to other parts of scenes or other objects are attached to each of the mesh, transparent or openwork supports 32, extending forwardly from the rear edges of said mesh, transparent or openwork supports toward but terminating short of the,front marginal strip 32.

The arrangement shown in Fig. 2 of the drawing should be suflicient to make clear an appro-- priate relationship of these picture strips 34 with respect to each otherand with respect to the background on the support 13. As there shown, these picture strips extend forwardly having their front edges of irregular formation, as shown in Fig. d

and by the projected reflection thereof in Fig. 1. Thus, the part of the perspective picture represented by the strip 34 on the upper support 31 is the foreground 35; the part of the perspective picture represented by the strip on the next lower support 31 represents the middle portion 36; the part represented by the strip on the lower support 31 represents the background 37; and the background of the support 13 represents the sky portion 38 of the projected perspective view or scene. p

Lamps 39 are supported in a concealed part of the cabinet below the mesh, transparent or openwork supports 31 and cast their rays upwardly toward and against the reflector 7 along the front picture edges 34, the mesh, transparent or openwork supports 31 forming no obstruction to these light rays particularly when any small or insignificant shadows on these supports 31 are dissipated by the raysof the lamps 11.

Flanges 40 on the ends of the respective rollers.

or spools 14, 15 and 16 and their analogues that are attached to the shafts 18 guide the frame strips 32 of the mesh, transparent or openwork supports 31.

The motors 26 and 27 may be controlled by any appropriate switch or controlling mechanisms for intermittent operation thereof in order to stop and start said motors, as desired andas required to obtain best results if such results are obtained by intermittent operationof the scenes portrayed on the picture strips 34. Devices and mec L l'flll for intermittently operating motors are well known andare not illustrated in the an nexed drawing.

In operation of this machine, the desired picrollers or spools 14, 15 and 16 and the analogues thereof on the shafts l8.- Then one of the motors 26 or 27 is operated, while the other remains stationary, to rotate the corresponding rollers or spools and wind thereon simultaneously and at equal or varying speeds the mesh, transparent or openwork supports 31, this being permitted by the escaping action of the clutch members 19 corresponding to the motor that is not operating. The motor may be stopped and started as desired to present the scenes in the chosen or most efliective manner.
