Application filed, SeptemberlG, 1919, SeriaLNo, 324L135. RenewedMayS, 1325.

My invention relates particularly to an apparatus by means ofwhich pictures or subjects ofvarious kinds may be displayed, but relates especially tosuch a display apparatus adapted for use. in advertising.

The objectvof my invention is to provide anapparatus by means of;which subjects of various kinds. may be displayedto great advantage. I

Further. objects of my invention are to provide. anapparatus by means of which a changeable picture may be displayedand in addition thereto a number of other nonchangeable pictures'may be displayed while utilizingthe same source of light as used in connection with the changeable picture.

Stillanother object of my invention is to provide. attractively and uniformly blended lighting effects in connection with the dis-, play of pictures above referred-to.

Again, another object of my invention is to provide such an apparatus in whichthe movable picture elementsmay be readily replaced.

Further, objects'of'my invention will appear from the detailed description thereof contain-ed hereinafter.

\Vhile my invention is capable of embodiment. in many different forms for the purpose of illustration I have shown only certain forms of my invention in the drawings in which: r

Fig. 1 is a front elevation of an apparatus made in accordance with my invention;

Fig. 2is a plan view of the same Fig.3 is a plan view of a modified form of my invention; and I Fig. l is a front elevation of still another modified form of my invention;

Fig. 5 is a vertical section taken on line 5-'5 of Fig. 1.

In the drawings referring to Figs. 1 and '21 have shown a frame 1 of wood having a recess2 on its rear face to receive a composite picture 3 which may be enclosed in a permanent metal frame 4 to. protect the edges thereof. saidslot being also arranged to receive. in the rear of the picture 3 a lined screen 5, protected by a metal frame 6 at the. edges thereof, and at the rear of the lined screen 5, also, a lightdiffusing plate 6 which may beof glass and which may be enclosed in a metal-protecting frame 6*. The composite. picture 3 is comprised of a .plate such. forexampleas glass adapted to, transmit light, the same carrying thereon a plurality ofpictures each of which iscomprised of a plurality of lines so arranged that the linesof one picture fall between the lines of the other picture. The lined screen 5 is comprised of a plate of material adapted to transmit light, such for example as glass carrying aseries of. parallel lines. The lined screen oriss'paced a short distance; tothe rear of; the composite picture 3 by reason of the protecting frames 5: and 6. It will be-urrderstoodthat therec ess, 2is open at the top but closed at the bottom. At the rear of said recess2 thereare two strips of metal 7 andS held in placebyscrews 8 which extend over the edge of the recess 2 in order to form a slot with the same for the receipt of the plates 3, 5 andG. Soldered to the strips of metal 7 and 8 there are provided four flanged spacing members 9 said spacing members 9 being soldered at their other ends to a housing 10 having twoangular light reflecting surfaces 11 and 12. These surfaces 11 and 1 2 areturned over at their upper and lower ends so as to secure in place upper and lower closures 13 and 14. Said-upper, and lower closures support respectively lamp sockets 15-and 16 carrying white or colored lamps 15 and,16 to which they are secured by screws 17 while electric connections for thesame are made through a socket 18extending out of the rear of the housing 10. At the forward edge of the upperclosure13 there is a slotted edge 19 formed by bending the edge of the upper closure 13 intothe form of an 820, said slotted edge 19 being provided for supporting in place a picture 21 tov be illuminated by reflected light. 7 In order. to hold the picture 21 in the most advantageous"position, that is to SQQQYSO that it. will be slightly curved forwardly at the upper edge thereof, a strip 22is provided; which has bent over ends 23 and 24 to receive the edges of the picture 21. At their sides, the two reflecting surfaces 11 and 12-. also carry. slotted edges 25 and 26,; made in the same manner as the slotted edge 19 inorder to hold in place respectively pictures 27'and28. These pictures 27 and 28-may be held in a position with the free edges forwardly curved in order to securethe most effective illumination byform strips. similar to the strips 22, but preferably instead I use for thispurpose wires 29 and -having at their outer. endsbentover portions 31 and 32 to hold in place the edges of the pictures 27 and 28, said Wires being received at their inner ends in recess plates and 34: soldered to the rear of the housing 10.

The modification of my invention shown in Fig. 3 is constructed the same as the form of my invention previously described, except that in this instance the spacing members 9 are omitted, and the sides of a housing 35, made the same as the housing 10 but with the slotted edges and 26 omitted, are secured by screws 37 to the rear of the frame 1 in the place occupied by the strips 7 and'8 in the form of my invention previously described.

In the modification of my invention shown in Fig. i I have illustrated a mode of securing variations in blending effects which may be applied to any of the modifications of'my invention herein referred to. This is accomplished by providing in the rear of the frame 1 a housing 38 made like the housing 10 or the housing except that in this in-' stance'there are provided partitions 39 and 4-0 which may or may not extend up to the lined screen 5, but which preferably are spaced a distance to the rear thereof dependent upon the degree of blending of the lights desired. In this instance where there are used two partitions 39 and 40 there will be three lamps 41, 4:2 and 43 used, the lamps 41 and 4-3 being supported in the same manner as the lamps previously referred to, but the additional lamp 42 being supported upon the partition in a lamp socket 4 1 provided with currentfrom a socket 45. If the lights 41, 12 and 43 are red, white and blue respectively, the colors which are adjacent to each other will become attractively blended and the blended areas will depend largely upon the particular partition 39 or 40 separating the same. In this way very realistic effects can be obtained approaching the colors of natural objects or scenes, as for example water falls or landscapes, where subjects of this character are displayed by the composite picture 3 carried in the apparatus. However, it will be understood also that with-out the partitions, blending of colors may also be obtained, but in this instance the individual colors will not be obtainable at the top and bottom of the apparatus in their greatest intensity.

The operation of my invention will be understood from the description of the apparatus given above. From this it will be seen that the electric lamps, whether colored or uncolored, or whether of the same color or different colors, will display the composite picture by transmitting light through the same and when an observer passes in front of the composite picture, first one of the pictures of said composite pictures will be visible and then the other according to which of the pictures is cut off from view by the interposition of the lined screen between the composite picture and the source of light. The desired lighting effects, Whether of the same color or of different colors, and whether widely diffused or diffused to only a small extent can be obtained by utilizing electric bulbs of the desired colors and by making use of the number of partitions, separating the bulbs found most ,desirable and appropriate for the particular picture being displayed, and by utilizing such partitions of the desired depth. Whenever it is desired to display a different subject this can be readily done by removing the plate 3'from the recess 2 and substituting another composite picture plate for the same. In case the composite picture 3 is the only picture being displayed the form of my invention shown in Fig. 3 will be utilized, but where additional pictures such as the pictures 21,

27 and 28 are to be displayed by utilizing the same sources of light, such pictures are applied to an apparatus such as the apparatus shown in Fig. 1 for displaying the composite picture 3 is utilized to illuminate the pictures 21, 27 and 28 by reflected light. In order to change the pictures 21, 27 and 28, it is merely necessary to remove the strip 22 and wires 29 and 30 and then apply new pictures with said strip 22 and wires 29 and 30 to the ap paratus.

While I have described my invention above in detail, I wish it to be understood that many changes may be ,made therein without departing from the spirit thereof.

I claim:

1. In combination, a frame constructed and arranged to support interchangeable translucent composite pictures and a lam housing at the rear thereof, provided at the sides thereof with means for supporting interchangeable single pictures, a space being left between the housing and the frame for the passage of light at the sides of the frame whereby the single pictures are illuminated by reflected ligh 2. In combination, a frame constructed and arranged to support interchangeable translucent composite pictures and a lamp housing having two reflecting surfaces'located at an angle to each other at the rear thereof. provided at the sides thereof with means for supporting interchangeable single pictures, a space being left between the housing and the frame for the passage of light at the sides of the frame whereby the single pictures are illuminated by reflected light.
