W s. SLUTSKY ZJWAW SIGN Filed Jan. 22, 1957 INVENTOR SAMUEL SLUTSKY ATTORNEYS provide a sign of the character outlined which Patented May 3, 1938 SIGN Samuel Slutsky, New York, N. Y., assignor to Isidore Sherman, Brooklyn, N. Y.

Application January 22, 1937, Serial No. 121,735

15 Claims.

The invention relates to a light sign of the character in which light, either sunlight or artificial light, is transmitted through openings formed in the sign to cause sign characters to be visible from the front side of the sign either by direct light reflected from the front of the sign character or light transmitted therethrough or by both directly reflected and transmitted light.

It has been known in this art to provide sign characters in awnings and the like formed of flat sheets of glass or some semi-transparent composition material such as celluloid. One objection to these known structures is that they are quite liable to breakage, particularly in the case of those structures formed of flat glass, and in the case of the celluloid letters, they quickly become soiled and shabby and after they have been in use for a while become brittle and easily cracked and become checked especially when exposed to the elements.

The primary object of the invention is to will be unbreakable in ordinary'usage and which will be more or less permanent in appearance and maintain its initial brilliant appearance even though subjected to the various climatic changes to which exposed signs such as street and car signs are subjected.

Still another object of the invention and featuring economy in manufacturing costs and thus cheapness in the production of a marketable article is to provide a simplified construction which can be formed primarily from structural parts now easily available on the open market and the invention has for a further objective the providing of a structure which can be readily fabricated without necessity of using experienced labor in forming any desired character of sign.

Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawing and in part will be more fully set forth in the follow- .ing particular description of one form of sign embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawing:

Fig. 1 is a view in side elevation of the upper portion of an automotive vehicle, such as a truck, having positioned thereon a sign constituting a preferred embodiment of the invention, and with a a portion of one side broken away to show details of arrangement of the optical spheres herein featured;

Fig. 2 is a view in front elevation of the sign shown in Fig. 1 looking at the same from the right hand side of that showing and exposing four letter characters on its rear wall forming a rigid metallic support;

Fig. 3 is a view in front elevation of a portion of an awning showing a modified form of the invention mounted on a canvas forming a slight ly flexible support; and

Figs. 4. and 5 are detailed views of the lensor optical sphere mounting shown in the preceding figures, Fig. 4 being a view in rear elevation and. Fig. 5 being a vertical sectional view taken on the line 5-5 of Fig. 4 looking in the direction indicated by the arrows; and Fig. 6 is a View similar to the upper portion of Fig. 5 showing a modified form of mounting.

Referring to the form of the invention shown in Figs. 1 and 2, a box-like hood l formed of sheet metal is mounted with its open front side H facing forwardly of the vehicle V on which it ismounted, as shown in Fig. 1. The hood H includes opposite side walls 12 and I3, a-top l4 and a rear wall IS. The rear wall I is inclined from its top to its bottom downwardly and rearwardly away from the front side in such way that the rear face It is inclined to face upwardly and in position to receive light, either sunlight during the day time, or whatever artificially pr duced light may be along the street during night driving.

It is a feature of this disclosure that the inside of the hood is painted black or some other dark, non-reflecting color, so as to minimize the reflection of light which may enter the hood through the open front side ll. The front side of the rear wall [5 is painted with a color contrasting with its non-reflective background surface to form strokes ll of sign characters of which four are shown in Fig. 2 to spell the word Taxi. In the illustrated instance these strokes are nar. row white stripes arranged so that they are visible to a person looking into the open front of the hood by direct reflection of light and acts to display letters, words or other similar sign characters independent of the light transmitting features hereinafter described. When used as a vehicle sign, it is suggested that the hood be formed of sheet steel which has the advantages of providing a rugged structure which is not easily damaged and which can be treated conventionally to resist climatic effects. It is within the scope of the disclosure to decorate the outside of the hood and utilize it for advertising and other purposes, forming no part of the present disclosure. Instead of the metal rear wall 15 disclosed in Figs. 1 and 2, as a support for the light transmitting spheres hereinafter described, it is suggested in Fig. 3 that the support I8 be a drop or opaque sheet formed of canvas and like the support formed by the rear wall [5, is designed to be disposed in or hang in an upright position. Likewise in this canvas awning form of the invention, the sign character may be formed of a white stroke 19 in this case shown to be the letter H painted on a dark green canvas or it may be formed as a separate letter cut out of white oilcloth or equivalent fabric preferably waterproof and glued to the canvas or to the metal support it.

Within the stroke I! or 19 as the case may be, the support IE or I8 is provided with a plurality of circular openings 20 extending in line centered between the opposite edges of the several strokes. As a detailed description of any one of the openings will apply equally to any other opening reference is made to Figs. 4 and 5 for such details. Each opening is outlined by a two part circular mounting ring 2|, one of the parts 22 (see Fig. 5) is positioned on one side of the support and the other part 23 at the opposite side with four circumferentially spaced apart fingers 24, extending integrally from the part 22 and bent Z-shaped to extend through the support, through slots 25 formed therefore in the part 23 and bent outwardly to interlock the two parts to each other on opposite sides of the support. The inner periphery 26 of the mounting ring forms an annular part of a sphere in which is fitted an optical sphere 21 in one embodiment of the invention formed of red glass. The spheres are centered relative to their supports so as to minimize any leverage effect which the spheres may have on their supports, particularly in the case of the canvas support with its possibility of swinging movement in the wind. The mounting rings are so contoured that they snugly fit about the periphery of the optical spheres and tend to defeat any light leakage across the joint between each sphere and its support. It is within the scope of the disclosure to form the optical spheres as lenses but the spherical configuration is preferred, among other reasons, because the sphere can be purchased in the open market and thus can be purchased cheaper than specially formed lenses and for the further reason that if the spheres should tend to rotate about their contained axes in use, they would continue to function to transmit light therethrough irrespective of whatever position into which they might tend to rotate themselves.

In operation and referring first to the disclosure in Fig. 1, it is apparent that light which may impinge on the rear face H5 at any angle, or even diffused light, will be received by the rearwardly projecting semi-spherical portion 28 of each of the spheres and will be transmitted through the support and become visible as a circular spot of light defined by the forwardly projecting semi-sphericalportion 29 of the sphere 21. These several spots of light coact to form the sign character as for instance the twelve spots shown at the left of Fig. 2 forming the T in the word Taxi. Likewise in the showing of the portion of the awning in Fig. 3, the light at the rear of the awning will shine therethrough as seventeen spots of light arranged in the form of an H. These spots or light bulls-eyes are free of holding means between their outlining edges and are thus free of obstruction or shadows which might otherwise detract from the brilliancy of the spot showings.

In one embodiment of the invention, the spheres are about one half inch in diameter and are comparatively small with reference to the size of the word character of which each forms a part thus leaving a material amount of the supporting material between adjacent sphere mountings. In the showing in Fig. l, the spheres are held more or less rigidly in position and in the showing in Fig. 3 where there is the possibility in the canvas support to flex and twist the spheres are so spaced apart as not to interfere with each other while the sign is being blown by the wind in actual use. In this case the mounting rings are particularly effective in reinforcing the canvas in the parts containing the openings and even in the case of the metal structure shown in Fig. 1, the mounting rings tend to reinforce the cut edges of the openings in the thin sheet metal used and in both cases tend to transmit strain over a relatively large area of the support thus tending to avoid tearing strains on the support.

Referring to the modified form of the mounting ring shown in Fig. 6, there are disclosed two annular parts 30 and 3! formed of thin metal pressings, the part 30 includes a lens-engaging flange 32 bent outwardly and then bent back upon itself to form an outstanding circular flange 33 of double thickness of material for engaging one side of the support It or 18. The free edge of the flange 33 is provided with a plurality of circumferentially spaced apart outturned fingers of I which one is shown at 34 and which extends through the opening 26 and initially projects through apertures provided therefore in the outstanding flange 35 of the part 31. The flange 35 coacts with the flange 33 to clamp the support therebetween when the outer ends of the fingers are bent from their dotted line position outwardly in lapping relation to the flange 35 as indicated in full lines in Fig. 6.

By means of a structure as herein disclosed it is possible to provide a more or less permanent form of sign as the parts are formed largely of metal and the spherical light transmitting means, even when made of glass, do not easily break as would be the case if the openings were simply covered by a flat sheet of glass as in known prior structures.

While there have been shown, described, and pointed out in the annexed claims, certain novel features of the invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
