Description

Feb- 2, 1960 B. SPANGLER DISPLAY-SIGN INDICIA Filed March 8, 1957 nited States Patent O 2,923,080 DISPLAY-SIGN INDICIA Bernard Spangler, Philadelphia, Pa. Application March 8, 1957, Serial No. 644,848 5 Claims. (Cl. 40-130) The present invention relates generally to display signs and more particularly to individual display-sign letters, numbers or other indicia.

An object of the present invention is to provide a novel construction for display-sign letters, numbers and other indicia. Another object of this invention is to provide novel display-sign indicia which are easily and mexpensively manufactured,with a minimum of hand operations, and which are strong, long-lasting and capable of giving effective service, even under the mostadverse outdoor weather conditions, for long periods of time and with a minimum of maintenance and repair.

Other objects and advantages of the present invention are apparent in the following detailed description, appended claims and accompanying drawings.

For the purpose of illustrating the invention, there are shown in the drawings forms thereof which are presently preferred and which have been found in practice to give satisfactory results; it being understood, however, that the present invention is not limited to the precise arrangements and instrumentalities illustrated. v Referring to the accompanying drawings in which like reference characters indicate like parts throughout:

2,923,080 Patented Feb. 2, 1960 ICC flanged front or outermost edges to permit fluorescent tubing to pass from one letter to the next without disturbing the smooth and continuous configuration of the front or face portions of adjoining letters or the like.

AS can best be seen in the enlarged broken-away perspective View of Fig. 2, the pre-cast one-piece metal back or body 24 of each letter `18 and of each of the front and rear tail portions 20 and 22, is of generally U-shaped configuration with a back wall 26 which abuts the front wall 14 of the supporting member 10; the Walls 26 and 14 being provided with matching holes for the fastening screws 16 and also with larger-size matching holes, at

Figure 1 is a perspective view of a display-sign constructed of individual scriptV letters in accordance with the present invention.

Figure 2 is an enlarged fragmentary perspective View, taken in the area A of Fig. l; parts being broken away better to reveal the construction of the display-sign.

Figure 3 is a perspective View of a block-letter displaysign forming another embodiment of this invention; parts being broken away better to reveal the construction.

Figure 4 is an enlarged cross-sectional View taken generally along the line 4-4 of Fig. 3.

In Figs. l and 2, I have shown a display-sign conconfiguration), within which are disposed conventional transformers, resistances, starting mechanism and the like (not shown) such as are conventionally used with fluorescent tubing lighting. The ends of the member 10 may be provided with weather-tight closure lids 12,l as indicated in Figure 1.

To the front wall 14 of the member 10 are mounted, for example by screws 16, a plurality of script letters 18, whihc are also secured to each other in abutting endto-end relationship, to form a continuous unit spelling out a word or name, and with tail portions 20 and 22 at the front end of the first letter and the rear end of the last letter respectively, to provide a pleasing unitary construction which is substantially water-tight, strong and long-lasting, and so arranged that anyf Word or name or the like can be quickly and easily formed from a stock of prefabricated Vletters or the like; each letter or the like being formed from a back or body which is of precast one-piece light-weight aluminum allow or other suitable metal and from a complementary front or face which is of pre-molded one-piece light-transmitting shatter-proof synthetic resin or the like, the backs and fronts being capable of'forrning a weather tight peripheral seal along their peripheral edges and preferably also at the abutting ends of the metal backs. The abutting end walls ofthe metal backs of the'tindividual letters are preferably recessed rearwardlyor' inwardly 'from' the suitable intervals, to permit the tubing to pass from the member 10 (wherein the ends of the tubing are operatively connected to the transformer and starting mechanism, not shown, in conventional manner) into the letters 18.

The generally parallel top and bottom legs 28 of the U-shaped back 24 are provided with integrally-formed generally parallel and vertical diverging flanges 30 at their front edges.

An end wall 32 extends outwardly or frontwardly at both ends of the back wall of each letter body.A However, there is only a single end wall 32, shown in Fig. 2, at the abutting end of the back wall of the front tail portion 20. Similarly, there is only a single end wall at the abutting end of the back wall of the rear tail portion 22.

As can be seen in Fig. 2, the end walls 32 extend frontwardly only a fraction (for example one-half or less) of the distance of the legs 28. The abutting end walls of adjoining bodies or backs 24 are provided with matching holes, through which pass connecting bolts 34 provided with threaded nuts 36 to lock the adjoining backs securely together in abutting end-to-end relationship. I may provide a gasket 38 intermediate the abutting end walls to improve weathertightness.

Since the front edges 40 of the end walls 32 are recessed substantially from the flanged front edges of the legs 28, clearance is providedA in front of the end Wall edges 40 to permit the bent glass fluorescent tubing 42 to pass from one letter to the next as shown in Fig; 2.

In this way, it is not necessary to provide tubing connections for each letter and tail portion. In other words, theV tubing can be formed with only two or three sets of connections, in the intermediate or central letters of the entire word or name and can have its end portions body or back 24.

extend into the end letters and/or tail portions," as indicated in Fig. 2, with the tubing passing from letter to letter (or to tail portion) in front of the front edges 40 of adjoining end walls 32.

The complementary pre-molded one-piece front'or face 44 of each letter 18 and of tail portions 20 and 22 is preferably formed of light-transmitting shatter-resistant Synthetic resin or other appropriate material, which preferably is colored and also somewhat light-diffusing so that the light emanating from the fluorescent tubing is more or less uniformly distributed and illuminates the entire surface of the front or face. p

The front or face 44 corresponds in shape to its metal back 24 and is also generally U-shaped in cross-sectional configuration, with a front wall 46, top and bottoni legs 48 (which are not as deep as the body legs 2S), and diverging vertical flanges 50 at the rear edges of the legs 48. rl`he flanges 50 are constructed and arranged to abut the metal body fianges 30, although I may Vprovide an intermediate sealing gasket 52 to improve weathertightness.

A metal molding strip-54 of generally L-shaped crosssectional configuration is bent to follow the contour ofL is used toA fasten the face 44 to thel the letter edges and Thus, one wall 56 of the molding strip 54 overlies the front surface of the face flange 50, while the other wall 58 of the strip 54 overlies the juxtaposed free edges of the iianges 3 0 and 5 0, as shown in Fig. 2.. kMeidling holes are drilled or otherwise formed in the adjoining wall 56, and anges 30 and 50, to receive siutable fastening elements, for example self-tapping screws 60.

As indicated in Fig. 1, I prefer to form the molding strip 54 as well as the gasket 52 from individual bent sections which terminate at points spaced somewhat from the abutting end walls of adjoining letters or tail portions. In this way, there is continuous and uninterrupted gasketing at the zones of abutment of adjoining letters, so as to improve weathertightness.

From the :oregoing description, it can be seen that the novel I:onstruction of the present invention, permits the use uf sturdy and relatively inexpensive Prefabricated metal backs and light-transmitting synthetic resin fronts to form individual letters or other sign-indicia, which can be quickly and easily assembled into any desired sign, name or word or the like; the individual letters or the like being securely fastened to a supporting member and also to each other, and with provision for passing bent tiuorescent light tubing from one letter to the next, while maintaining an enclosed substantially weathertight structure.

The use of prefabricated standard letters (made up of complementary metal backs and light-transmitting fronts) which can be kept in stock and assembled into any desired name or word or the like greatly reduces both the time and the expense involved. Indeed, the novel construction of the present invention permits the production of extremely strong cast-metal signs at a fraction of the cost of conventional hand-made bent-andsoldered sheet metal signs heretofore used.

In Figs. 3 and 4, there is shown a modified embodiment of the present invention, which also constitutes a continuation-impart of the invention described and claimed in my co-pending application Serial No. 503,381, tiled April 25, 1955, now Patent No. 2,895,245.

In this embodiment, I have shown an elongated hollow supporting member 70, to the top wall 72 of which is mounted (by screws or the like) a base or back or body 74 which is die-cast or otherwise suitably integrally formed of aluminum alloy or other appropriate lightweight metal or the like, shaped, for example, into the,

configuration of the block letter A. The body 74 is generally U-shaped in cross-sectional configuration, with a back wall 76, forwardly-directed walls 78 and a diverging vertical peripheral iiange 80 at the forward end of said walls 78. A transformer unit 82 may be mounted near the bottom of one of the leg-portions of the A for example by screws 84 as shown in Fig. 3 and a removable access door 86, held by screws 88, may be provided in the back wall 76 adjacent the transformer unit 82, as shown in Fig. 4. Alternatively, the transformer unit may be mounted within the supporting member 70, in a manrlrer lnalogous to that shown n the embodiment of Figs.

an 2.V

Fluorescent light tubingV 42 may be suitably mounted within the body 74, preferably-somewhat recessed from the peripheral ange 80.

A complementary pre-molded one-piece front or face 90 is preferably formed of light-transmitting shatter-resistant synthetic resin or other appropriate material, as 1 n the embodiment of Figs. 1 and 2 and is also generally I J-shaped in cross-sectional configuration with a front wall 92, rearwardly-extending legs 94 (not as deep as the body Walls 78) and diverging vertical peripheral flange 96 which is constructed and arranged to abut the body ange 80, although, again, I may provide an intermediate sealing gasket 98.

A metal molding strip 54, like that shown in Figs. 1 and 2, may be used to interconnect the flanges 96 and 80, by means of screws 60, and an intervening sealing Y l 4 gasket 98 may be employed to increase weathertightness, in the manner described hereinabove.

In this embodiment, the matching flanged body and front portions can be quickly and easily asesmbled, using the metal molding, in very little time, to provide a sturdy and long-lasting construction which, being pre-cast and pre-molded, is comparatively inexpensive and far superior to the hand-made bent-and-soldered sheet metal constructions heretofore employed.

The present invention may be embodied in other specie forms and, therefore, the foregoing embodiments are to be considered in all respects merely as illustrative and not restrictive, reference being made to the appended claims as indicating the true scope of this invention.

Having thus described my invention, I claim as new and desire to protect by Letters Patent the following:
