several sections, depending on the overall size of the sign; In front of the panel are provided horizontally extending supporting members for receiving sign letters or characters, or, generally stated, the objects for display which are then visible, forming the desired message in silhouette against the background of the display panel in daylight and also in the dark when the panel is illuminated.
The previously mentioned co-pending applica tion is concerned with a device for supporting on such a: sign a pictorial transparency and utilizing theillumination of the display panel for illuminating; the transparency. The term pictorial: transparency denotes a sign made of paper or other suitablev material which is transparent or. translucent, and is either pictorial or descriptive, conveying a certain message. Such trans parencies' are furnished, for example, by producers of motion pictures and illustrate certain actors of a play or certain scenes from a play. In the general use of the invention this particular phase does notv play any material part; such transparencies may also be used in fields entirely different from the theater field, which is mentioned merely as an illustration because many such signs are used as marquee signs in front of motion picture houses. The co-pending application covers a device for displaying such transparencies on signs carrying a descriptive or informative message of. which the transparany is made a novel part.
The structure of the copending application comprises a frame. having a backwardly extend- 1941, Serial No 391,768
i'ng flange which is provided with means, forexample, notches, for engagement with the supporting members on the sign The transparency isput between two members, for example, glass panes, forming a unitary assemblage therewith.
The principal-object of the present invention resides in furnishing an improved structurefor mounting and displaying such a transparency or the like. Several distinct improvements are in cluded in the new invention; 1stthe frame is provided with a translucent or transparent front panel made, for example, of glass, which forms a'substantially permanent structure therewith;
2ndmarginal holding or retaining members areprovided onthe frame in back thereof, and therefore in back of the permanently mounted front pane; 3rd-the new structure carries improved means for preventing seepage of moisture into the interior of the frame, thus protecting the transparency mounted therein; 4ththe frameis so constructed as to provide means for draining moisture from the bottom thereof; 5ththe new structure is provided with means for facilitating the insertion and also the removal of the transparency.
The above intimated objects and features, and additional object not yet mentioned, will appear from the detailed description. rendered below with reference to the accompanying drawings. In these drawings:

Fig. 6 shows one corner of the new frame for supporting the transparency; and
Fig, 7 is a section taken through the assemblage shown in Fig. 6 along lines -ll.
Like parts are indicated by like reference numerals throughout the drawings. Structural elements and detailswhich may be assumed to be Referring now to the drawings, particularly to Figs. 1, 2 and 4, numeral N indicates a sign box having a back wall l2 and a frontal opening I3 (see Fig. 2) defined by marginal ledges of the box such-as noted at M, I5 and I6. Brackets such asnoted in Fig. 2 at 17 and 18 form with the corresponding ledges channels in the forward p01? tion of the sign box for holding a translucent or transparent display panel IS. The sign may be provided with one or with several display panels, depending on the over-all size thereof. In the example shown in Fig. 1 there is indicated at part of a second display panel. The first panel |9 is mounted in a frame comprising the upright members 2| and 22 which are interconnected by the horizontally extending supporting members or carriers indicated at 23, 24, 25 and 26. The second display panel 20 (and each additional display panel that may be provided on the sign) is equipped with similar uprights such as 21 at one end and a like upright at the other end, these uprights being interconnected by means of horizontally disposed supporting members such as 28, 29, and 3|. Letters such as shown in Fig. 1 at E and W may be disposed on the horizontal supporting members extending in alignment in front of the display panel or panels of the sign. The display panel or panels are illuminated from light sources such as indicated at 32 and 33, which are mounted on brackets 34 and 35. The structure so far described is known, and details thereof which are not specifically covered herein are disclosed in the previously mentioned U. S. patents.
The new device for supporting the transparency is generally indicated at 4|]. It comprises a frame having a frontal marginal ledge 4| provided with flanges 42, 43, 44 and 45 extending rearwardly therefrom. These flanges carry means, for example, notches, as shown, for engagement with the horizontally disposed supporting members on the sign. Different supporting means may be provided if desired or necessary, in accordance with the specific sign structure in which the new device is to be used. The frontal ledge 4| slopes downwardly and inwardly, as may be best seen in Figs. 5 and '7, forming a marginally extending interiorly disposed pocket. Adhesive is disposed in this pocket for cementing to the back of the ledge 4| a transparent or translucent frontal pane 5| in relatively permanent engagement with the frame. This front pane 5| thus covers and closes the display opening of the device formed by the ledge 4| and constitutes one of the means for preventing seepage of moisture into the interior of the frame.
A strip of resilient material such as rubber is positioned within the frame near the inside edges thereof and in marginal contact with the rear surface of the front pane 5|, forming in the frame, as it were, a shallow well. The four sides or sections of the strip are indicated in Fig. 3 at 52, 53, 54 and 55. This strip may be made of one piece or of several sections, as desired or necessary. The strip or strip sections, 52-55, inclusive, are held in position against the rear surface of the display pane 5| by means of angular sheet members 56, 5?, 58 and 59. These angular members are shown attached to the flange or flanges of the structure by means of screws and nuts; if desired, they may be welded or riveted to the inside of the frame; or they may be attached in any other convenient and approved manner.
The angular members 56 and 58 may be narrower than the resilient strip sections 52 and 54 as shown in Fig. 3. The angular strip 59 may be somewhat wider so as to project above the underlying resilient strip section 53 and to form a bottom channel with the frontal pane 5|, as is particularly apparent from Figs. 5 and 7. The angular member 51 may be made still wider in order to form with the frontal pane 5| a deeper top channel, as shown in Fig. 5, for insertion of the transparency and the protective rear pane 6| in a manner to be presently explained. The top and bottom of the rear of the protective pane 6| are in mounted position of the pane immediately in back of the angular members 51 and 59, as is apparent from Fig. 5. These members do not necessarily bear against the protective pane; they form top and bottom channels in which the pane is removably held. The width of the channels formed by the angular members 5! and 59 may correspond approximately to the thickness of the protective panel 6| added to the thickness of the transparency. All these angular members may be secured in place before the transparency and the pane 6| are placed in the frame.
The transparency 50 and the protective rear panel 6| are inserted into the device as follows: They are held together and the upper edge of the assemblage is pushed into the upper channel formed by the frontal pane 5|, the upper rubber strip 55, and the overlapping holder member 51. The lower end of the transparency and the protective pane is then pressed down against the front display pane or panel 5|, and is allowed to drop into the bottom channel formed by the front display pane, the rubber strip or section 53 and the holder member 59. The inside edges of the rubber strip or strips forming the walls of the well are on all sides in close proximity to the edges of the protective rear panel 6| and the transparency 6|), the assemblage of the transparency and the rear panel fitting snugly into this well. The resilient marginal strips (sections 52, 53, 54, thus form additional means for preventing seepage of moisture in between the two transparent panels 5| and 6|, the first panel 5| being stationary and the second panel 6| being removable with the transparency.
As an added protection against the seepage of moisture into the interior of the supporting device, I have provided a stri 10 made of' resilient material, for example, rubber, secured to the top section 42 of the flange by means of a suitable holder 1| in such a manner that the edge of this strip 10 is in contact with the surface of the display panel or panels of the sign, for example, panel IS, in front of which the transparency is mounted. The bottom section 44 of the flange is cut away, leaving a space 12, particularly as shown in Figs. 5 and 7, so as to facilitate the drainage of moisture downwardly from the interior of the device.
The device has been subjected to exhaustive tests, simulating and even exceeding weather conditions that may be encountered in practice. Water was sprayed onthe device from fire hose for a considerable time and from every conceivable angle of approach. It was found that moisture did not enter into the transparency and did not affect the transparency.
In order to facilitate the exchange and removal of a transparency, I have provided means, e. g., a thin leaf spring or springs such as indicated in Figs. 6 and 7 at 80, the spring consisting of a simple angular member which is inserted between the frontal display panel 5| and the resilient strip 53, and may be held in position by means of the bracket 59. When the transparency with its protective rear panel is inserted and is in display position, the leaf spring or springs will be pressed down and will assume the position shown in full lines in Fig. 7. However, when the assemblage comprising the protect ive rear pane and the transparency is lifted from the lower mounting channel into the dotted position shown in Fig. 7, the spring or springs 80 exert an outward pressure and tend to force the protective rear pane and the transparency out into the dotted position shown in this figure. The transparency and the protective rear pane can now be easily removed from the device. The leaf spring or springs may be disposed and positioned so as to be completely in back of the frontal ledge of the device.
The drawings show certain parts somewhat distorted as to relative size and placement so as to emphasize new details. The structure shown in the drawings, therefore, should be considered merely in the nature of an example to be interpreted and used with such sensible latitude as appears from the scope and spirit of the entire disclosure.
