W. HERRSCHAFT DISPLAY SIGN Filed Nov. 5, 1926 3 Sheets-Sheet 3 M w n DISPLAY-T itlpliczrtion lllCtl November My present invention relates to luminous .isoluV ns employed for adve ising and ms l l erred application to'signs of the type used in display rooms and store win- (lows and not exposed to external weather conditions.
Among the objects of the invention are to pr vide a display sign of low cost and rrc'g'ed construction which can be easily d expeditiously made up without the use t any tools whetsoey r, to provide at will n1 reading matter or color eilect desired. and which. in use, produces a strikingly atl'l tive and luxurious effect with a minim 1 consumption of electric power.

In back of the window panel, will be mounted a translucent paper sheet 26 affording a titlea removable longitudinal lock strip 31 interlocks with the downturned upper edge 32 of the backing plate and. with the rear rail of the window supporting strip 23. This lock rail extends preferably the entire length of the sign and has an outstanding rectangular handle portion 33 by which it can be easily shifted for application and removal thereof.
The backing plate has longitudinal holdi-Irg strips 84 soldered thereto, which serve to mount preferably translucent colored strips 85 of gelatin or paper, that may be placeably held in back of the windows. Vertical rods 36 are soldered in position at the various rails of said backing plate at the rear thereof and serve to= stiffen the construction and also to retain the gelatin strips against curling out of place, due to the heat of the lamp.
A preferred character unit is shown. in Figs; 5 and 6. It comprises simply a rectangular element of ordinary paper of the grade commonly used" for paper drinking cups stamped into a rectangular tray shape, as shown, and including, in particular, a rectangular face 37, integral upstanding side walls 88 and end wall- 39, and preferably an integral rectangular flange -10 extending outward from the end and side walls. The excess' material is gathered in, to form crinkles 41 at the corners of the tray and the flange rim, which serve, moreover, to stiffen the tray. The symbol 42 is preferably printed or painted with an opaque pigment both on the exterior and interior face of the tray base. The tray after being formed preferably by a die, is impregnated in a bath of.
paraffin and then allowed to dry.
The spaces between words are formed by trays similar to that described, but rendered completely opaque throughout the entire surface thereof, one of said spacer units being shown at 4 3.
It will be understood that in making up any particular sign, the selected character units or trays are laid into the corresponding open windows 22 of the front plate or character frame 21, which, for this purpose, is laid down in horizontal position, as shown in Fig. 4, whereupon the hinged backing plate 28 is tilted downward and locked in position by applying the lock strip 31. l.hereupon, the cover 17 is raised and held closed by means of the wing nut-18. It will be seen that each of the characters is securely clamped in position at its border flange 41-0 between the slats making up the contour of the correspondingwindows in the character plate 21 and the corresponding slats of the backing plate. The character plate positions the character units and the backingplate locks them in place.
As best shown in 3, the rims lO of the character trays are so securely clamped between the slats of the character frame 21 and those of the backing plate 28 that no light will escape around the rims of said trays. The light, colored by the gelatin strips, is transmitted only through the face 37 and the side and end: wallsof the trays, producing the rich three dimensional elfect of thick solid, illuminated colored, frosted glass, or of marble or amber, rigidly secured in corresponding bezels and protruding outward therefrom. The light emanates not only from the face but also from the side and end walls of the character units. Y
The character units though of trifling cost are not brittle as glass; they are form sustaining and not subject to injury by handling or by heat due to the lamp. The tray units not in use can be kept in nested stacks, since their side and end wallsflare as shown,
without danger of marring by abrasion or adhesion.
W hil'e the character units are preferably made in the specific manner described, it will be understood that it would be within the scope of my invention, in its broader aspect, to press the same directly from paper pulp. It would also be within the scope of the i nvention to substitute for paper, other fabrics, such as vellum, oil. cloth, thin leather and the like.
lVhile I prefer to form the holding rim of the character unit as an integral part of the character block or panel, it is within the scope of the invention to provide separate and distinct holding clips or other att-achii'ig means for the character units.
In Fig. 7' is shown an alternative cmbodi ment for locking the backing plate 28 in position. The various parts of Fig. 7 are substantially identical with those of Fig.3 and corresponding parts are designatedby the same reference numerals primed. In this connection, however, I have shown in lieu of the lock strip 31 extending longitudinally of the backing plate a transverse locking-rod 50. This rod has an upturned handle end 51 and is passed through a pair of loops or staples 5:2 and 58, one at the lower channel of the window 24; and the other at the base of the frame. The rod 50 of which several may be used, when placed in positionas shown reacts againstthe various channels or runners 34 on the backing frame and eii'cctively prevents buckling of the same. WVhen it is desired to replace the characters, the rods 50 are simply withdrawn and the backing plate is released. The handle 51 may be turned iiat against the window when the parts are assembled.
It will thus be seen that there is herein described an apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.
As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.
