My invention is especially concerned with signs of the type in which opaque indicia are disposed in the path of light transmission or re?ection. 10 The term “sign” is intended to include any suit able device which conveys a thought or impres It is the primary object of the present inven~ tion to devise an improved multiple-direction sign in which a plurality of signi?cant images are clearly visible from a plurality of widely separated points of obseruation. The several images may be identical or may differ from each other, but usually they will be identical as is desirable for example, in a store-front advertising sign designed to be read from both directions on the street and perhaps also from a point across 25 the street. In connection with the foregoing it is a further object to construct such a sign for economical 15 and eifective operation with a common source of light for producing the several signi?cant images. 30 (Cl. 40-130) ranged behind the third set and disposed to pro duce re?ection of light from said surfaces to ward said parallel sets. The present invention further contemplates a multi-directional sign in which the indicia are 5 readily detachable and in which like indicia may be interchangeable throughout the several sets of indicia. Another object of this invention resides in con struction of an illuminated sign in which the 10 sign structure is supported or carried by the con duit or piping which houses the electrical feed The present invention relates to multi-direc tional or multiple sided signs and particularly to signs of this type which are visible from a plu It is a major object of the present invention to illuminate one or more sets of opaque indicia in such manner with .a background of re?ected light as to render said indicia clcarly'readable from remote points and very easily and correctly 35 readable from all points within the range of visi bility. This object is contemplated particularly with comparative reference to signs heretofore constructed in which either the indicia themselves or the background for the same have produced 40 such glare as to make them readable with diffi cultly at all ranges and illegible when viewed from relatively remote points. More speci?cally the present invention con templates an illuminated sign in which at least 45 two sets of opaque indicia are arranged to face in respectively different directions, and in which a pair of re?ecting surfaces are illuminated from a common light source to form accentuating background for said two sets of indicia. It is an object of my invention to devise a 50 three-way sign comprising two substantially conduit assembly. 15 The foregoing and further and more speci?c objects of the present invention will become more clear from a study of the following descrip tion when taken in conjunction with the accom panying drawing and the appended claims. Figure l is a front elevational view of one pre ferred multi-sided sign structure embodying the present invention, the view being obtained from a point of observation in front of a set of in dicia that is arranged between two further sets of indicia; Figure 2 is a horizontal section taken through the device of Fig. 1 substantially on the plane of line _2--2; Figure 3 is a view in left side elevation of the device of Figs. 1 and 2, as seen when looking to ward the line 3-—3 in the direction of the arrows; and Figure 4 is a view in rear elevation of one of the letters of the front set of indicia, viewed on the plane of line 4-4 in Fig. 2. With continued reference to the drawing, wherein like characters are employed to designate like parts, the illustrated sign consists essentially of an upright structure S for concealing an elec ' trical conduit and for affording a pair of re versed light re?ecting surfaces; a pair of sets of indicia, M and N, substantially identical and arranged back to back adjacent the respective 45 re?ecting surfaces; and a third set of vindicia, P, substantially perpendicular to the sets M and N and designed to conceal a source of illumination for the pair of re?ecting surfaces. The upright structure S comprises a vertical 50 member 4, preferably formed of sheet metal in parallel sets of indicia and a third set of indicia such manner as to provide a pair of oppositely approximately perpendicular to said parallel sets, facing and concavely curved re?ecting surfaces 5 interconnected by a bridge portion 5. The sur means affording re?ecting surfaces between the 55 parallel sets, and a source of illumination ar 20 ' In the drawing: faces 5 as shown are quarter-sections of substan 55 2 2,111,455 tially parallel cylinders but, as will be apparent later the curvatures as well as the relationship of the surfaces may be varied in accordance with possible variations in other parts of the assem bly. The rear side of the member 4 has a pair of parallel Wings 7 extending from top to bottom, and at the bottom the member is closed by a plate 8 having an upstanding flange 9 which ?ts within said member as a closure and strengthening 10 means. A similar plate may be provided at the top. The structure S may be secured directly to a store front or other chosen support in any de— sired manner but preferably it is supported by a 15 rigid conduit assembly which comprises a ver tical main pipe 10 having a series of vertically spaced horizontal branch pipes [2. The trunk or main Ill carries electrical wires l3 which supply current to branch wires in the pipes l2. Pipe [0 extends through the plates 8, and the series of pipes l2 extend through the bridge 6 to support the set of indicia P in a manner yet to be de scribed. The branch wires lead from pipes 12 to insulated sockets it which carry conven tional electric lamps or bulbs Hi. The sockets M are detachably supported in desired positions by the indicia P as will be described later. It will be understood, for example, that the 40 in Fig. 2 the letter “M” is shown in section as comprising not only a front face plate 23 in the shape of the letter but also a plurality of back wardly turned or attached ?anges 24, 25, 26, etc., which constitute, in effect, a single ?ange fol lowing the outline of the letter. This letter struc ture includes an integral or rigidly attached strip of metal 21 at its rear, parallel to the front plate 23, for the purpose of securely mounting the letter upon the forward end of one of the branch 10 pipes 12 by means of a pair of nuts 28 and 29, for example, threaded upon the pipe terminal. In like manner the other letters of the set of indicia P are detachably secured to the other pipe branch extremities. 15 Each letter of the set P preferably carries a plurality of lamps l5, although it will be appre ciated that one or more of proper capacity will suffice when properly located to illuminate the background and give the desired light reflection. 20 In the illustrated form, where four lamps are provided where possible for each letter of the alphabet, the lamps are located at spaced points, in symmetry. In the letter “M”, for example, the lamps are concealed in the four corners of 25 the letter. The sockets Ill preferably are made in two separable parts, each detachably carried by an apertured sheet metal bridge 3| which is back or open side of the structure S faces the front of building, that the front or bridge 6 faces toward the opposite side of the street on which the building is located and that the con cave re?ecting surfaces 5 face generally in oppo site directions “up and down” the street respec tively. The wings ‘I of the structure S have a plurality of horizontal brackets l5 secured there welded or otherwise secured to the side ?anges of the letter structure. From the foregoing it will vbe seen that, as the bridge 6 is very narrow much of the light from the lamps 15 will be transmitted to the surfaces 5 and thence re?ected by them in the general directions of the two sets of indicia. M and N. 535 The latter, like the indicia P, comprise letters to by fastening assemblies l1, these brackets ex tending toward the front of the sign and, where which have opaque front plates 36 in the shape of letters. They also preferably have ?anges 32 the three sets of indicia M, N and P are to be on one side which give them better form for var substantially identical, being equal in number ious angles of approach in the daytime and for 40 assisting somewhat in proper re?ection at night. to the branch pipes l2 and arranged in the same vertically spaced relation as the latter. In order that the sign may have a pleasing appearance in the daytime, as well as at night, the rear side of the structure S is substantially framed in an ornamental rectangle comprising The indicia M and N stand out very clearly in silhouette outlines as the result of re?ected light and illuminated background produced by the re spective curved surfaces 5, 5. The indicia P have .a similar appearance, partly as the result of il horizontal top and bottom pieces l8 and I9, and vertical side pieces 29. These four pieces may be luminated background and partly following from secured to the structure in any suitable manner, or may be interconnected at their ends to hold them in position as a unitary frame. the surfaces 5, 5 and the bridge 6. Each set of re?ection of light toward their rear sides from indicia can be seen from greater distances and much more clearly within the range of visibility, The apparatus thus far described comprises than can a set of indicia which transmit light or the means for supporting and illuminating or are outlined by direct glaring light. The surfaces 5 may consist of polished metal, rendering visible the three sets of indicia M, N and P, which in the illustrated example are designed to spell the word “Thom” vertically so that it will be seen in triplicate from three dis tinctly different directions. The letters of course are constructed in block or other conventional type, and it will be understood that other sym bols, or pictorial representations, may be sub stituted. The individual letters of the indicia M or enameled or painted material of any sort. Preferably they are provided by painting the illus trated smooth sheet metal structure in a color such as cream, white, or chrome yellow. A varia tion or shading of these colors can be employed effectively. The interior surfaces of the letters 60 of the set P preferably are polished orcoated with light~re?ecting material. . and N may be identical per se, although some what differently arranged and are mounted on The several sets of indicia are rendered clear ly visible at night with a single source of illumi the brackets l6 substantially in parallelism by nation, thus effecting large economy in opera tion. For example, a letter 18 inches in height and its two associated wing letters can be fully screw and nut assemblies 22 or any suitable equivalent which, preferably, is designed to per mit ready attachment and detachment of the letters. The letters of indicia P are considerably different, as follows. The letters of indicia P must be designed to conceal the electrical lamps l5 from view in all directions from which the sign is readable and accordingly each letter is constructed with one or more rearwardly turned ?anges. For example, illuminated with a single 100 watt lamp, or with two 50 watt lamps, or with four 25 watt lamps. The letters are readily detachable, and most of the letters of sets M and N are interchangeable by reversing them front to back and top for bot tom when transferring from one set to the other. All letters of these two sets may be made fully interchangeable by duplicating the ?ange 32 for 3 2,111,455 each letter; and of course they may be designed to form stock portions for the more complex let ters of the series P. The structure S may be made up in sections of stock length so that it can be assembled in suitable lengths for a sign of any number of letters or symbols. The two sets of indicia M and N are shown in pair of upright members having re?ecting sur faces of approximately quarter-cylindrical curva parallelism but it will be appreciated that they structures disposed respectively opposite the said may be angularly arranged while still separated re?ecting surfaces in positions where each stands out against the re?ecting background formed by 10 10 by the structure S, and that the curvature of the surfaces 5 may be varied to obtain maximum light re?ection toward these sets of indicia while retaining a suf?cient background of illumination for the set of indicia P. Various other changes obviously may be made 15 within the scope of the invention, and therefore I desire to be restricted in protection only with in a reasonable interpretation of the appended 20 claims. I claim as my invention: 1. A multi-way sign comprising two substan tially parallel‘ sets of indicia, and a third set of indicia arranged approximately perpendicular to so ture, a light source common to said surfaces and disposed adjacent one vertical edge of each of them, an image'forming structure concealing said light source and having said surfaces as a back ground, and a pair of further image forming said surfaces. -, 5.
