18 Claims. (01. 40-130) Our invention relates in general to display devices and has more particular reference to an illuminated silhouette sign of novel construction and arrangement and productive of extremely sightly eye-arresting efiects.
An important object of our invention is to provide a silhouette sign in which solid characters, forming subject matter of display, are illuminated from behind in order to provide a distinctive silhouetted appearance.
Another important object is to provide a sign having characters, the sides of which are formed with a light reflecting coating and the fronts of which are formed with a substantial non-reflecting dark coating, the sign including means to illuminate the character from behind in such a way as to illuminate the sides of the characters in order to cause the front of the letters to stand out in brilliant relief.
Another important object is to provide means to support block characters of the class described while illuminating them from the rear in order ,to give the characters a silhouetted appearance. Other important objects reside in the means for illuminating the sign character from the rear including a reflector and concealed lights, preferably of the electrical discharge are type; the provision of a casing in which to display the characters while illuminating them from the rear, the means for mounting the block characters in the casing and in general the provision of the extremely sightly and unusual silhouetted appearance of the letters in the sign.
One of the important features of the invention is the utilization of discharge are illumination, such as is produced by the discharge of electrical arcs through a gaseous conductor medium as in the so-called neon" lamps, in conjunction with block characters having a substantial thickness and having the front coated with any dark, preferably black, pigment while the sides of the character are covered with alight refracting pigment, such as aluminum, or silver paint, for the purpose of reflecting the neon light so that the darkened portions of the characters will stand out vividly against the illuminated sides of the characters and against the illuminated reflector back-ground.
Numerous other objects and advantages of the invention will be apparent as the same is more fully understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment 35 of our invention.
"to provide an upwardly facing wall 35 at the for- 'in place;
Figure 5 is a similar sectional view illustrating another mode of making the sign, while 7 Figure 6 shows a still further modified construction.
Figure 7 is a perspective front view of a portion of a sign embodying our invention;
Figure 8 is a vertical section taken substantially along the line 88 in Figure '7; and
Figure 9 is a perspective view showing details of construction.
To illustrate our invention, we have shown on. the drawings in Figures 1 and 2, a sign comprising a casing 11 preferably formed of sheet metal. The casing illustrated is of rectangular construction and has one or more hooks or rings 13 by which the sign may be supported. The casing comprises a top wall 15, bottom wall 17, side walls 19 and a rear wall 21. The front of the casing is open to receive a reflector member 23, which extends throughout the length of the casing and has an upper edge secured to the forward edge of the top wall 15. The reflector member 23 extends preferably vertically downwardly of the top 15 to form a panel 25 at the lower edge of which the reflector member extends inwardly to form a downwardlyvfacing wall portion 27 from the inner edge of which the reflector member extends downwardly within the casing to form a reflector 29 facing outwardly of the open side of the casing. The lower edge of the reflector 29 rests upon and is supported by the bottom of the casing and extends forwardly to a point 31 100 spaced from the forward edge of the bottom 17 of the casing, thus the reflector member 23 is 011- set upwardly to form a wall 33, at the upper end of which the reflector member extends forwardly ward end of which the reflector member is bent downwardly and extends to form a panel 37, which terminates and is secured to the forward edge. The casing and reflector as aforesaid may be formed of sheet metal pieces suitably formed no and welded together and strengthened as by the angle brackets 39, as is well known in the sheet metal art. One or more illuminating devices 41 are suitably mounted as on supports 43 within the casing behind the wall 33 in position to illuminate the front surface of the reflector 29, which is preferably coated with a suitable light reflecting paint in order to brightly illuminate the opening between the side walls 19 and the oppositely facing wallportions 27 and 35.
We prefer to employ discharge illuminating elements, such as the gas glow tubes illustrated which produce light having stroboscopic characteristics, for the purpose of lighting up the sign, although it will be obvious that other illuminating elements may be employed. To illuminate the lamp 41, particularly if the same requires high voltage electrical power as where the lamp is a discharge are device, such as a neon tube, we may mount a suitable transformer 43 within the space defined between the top wall 15, the back wall 21 and the reflector member 23. This transformer may be powered from a suitable external electrical source through the conductors 45 and in turn may be connected as by the conductors 4'? to excite the illuminating devices 41.
To complete the sign, we arrange characters 51 between the upper and lower walls 27 and 35, that is to say, in the casing opening in front of the reflector 29. These characters are preferably block letters having a substantial thickness and the sides 53 and back 55 of the letters are preferably coated with a suitable light reflecting paint, which may be the same as that used upon the front face of the reflector 29. The front or forwardly facing surfaces of the characters 51 however, are preferably coated with a dark pigment so that when the illuminating-device 41 is excited, the dark surfaces of the characters 51 will be silhouetted against the illuminated background and will provide a very unusual, beautiful and eye-arresting appearance.
The fact that the letters have a substantial thickness and that the sides of the letters are coated with a light reflecting material adds con siderably to the beautiful appearance of the sign; A suitable luminescent material, such as fluorocine may also be added to the light reflecting pigment applied to the sides of the letters in order to cause the sign to glow brilliantly when illuminated and in this way the contrast between the sides and the dark forward surfaces of the letters may be heightened.
The characters 51 may be secured in place in any suitable manner, as by the fasteners 57 comprising bent strips having ends 59 insertable through slots 61 formed in the panels 25 and 37 immediately above and below the characters. After the ends 59 are inserted the lugs may be rotated so that their outer ends lie against the forward surfaces of the characters 51 and be secured in place as by the nails or brads 63 thus providing a readily removable yet securely fastened device for retaining the characters in mounted position between the walls 2'? and 35 and in front of the reflector 29.
The front surfaces of the casing, including the panels 25 and 37 are also preferably colored with the same dark pigment with which the front surfaces of the characters are coated or a slight contrast may be made between the coloring of the panels 25 and 37 so that the characters may be more readily distinguished by daylight when the sign is not illuminated.
' In Figures 3, 4, 5 and 6, we have illustrated I modified constructions wherein the illuminated background for the letters is formed as a plurality of louvres 71, the front edges 73 of which are or may be darkened in order that the letters may appear to be superimposed upon a horizontally straited background. The opposed sides of the louvres '71 are coated with a suitable light reflecting pigment and illuminating devices41 are positioned within the casing behind the louvres so as to illuminate their light reflecting sides.
As shown in Figures 4 and 5, the lamps are mounted in suitable brackets 42 attached to the upper sides of the louvres near their lower edges. The lamps extend horizontally in the sign. In Figure 6, however, the illuminating devices 41 extend vertically behind the louvres. In any event the inner edge of each louvre overlaps the front edge of the adjacent louvre sufficiently so that the lamps are not visible from outside of the sign unless the same is viewed from a position substantially above the sign, which does not ordinarily occur since signs of this character are mounted at an elevation above the observer. In the event that a sign is mounted below the point of observation, the louvres may be slanted downwardly in order to hide the lamps.
The characters 51 employed in the sign shown in Figures 3 through 6 may be of considerably less depth than those employed in the embodiment illustrated in Figures 1 and 2 and may be attached to the sign by providing a bracket 75 in the form of a hook near the lower end of the character in position to hook upon the upper edge of one of the louvres, the upper end of the character being attached to the upper panel 25 of the frame as by the angle bracket 7'7, one flange of which is attached to the frame of the sign while the other is attached to a character.
Where louvres are employed, it is desirable to provide access to the lamps 41 through the back of the sign casing and to this end doors 79 are provided opposite each lamp as illustrated in Figure 5 of the drawings.
The casing also is arranged to form a space 81 preferably between the uppermost louvre and the top of thecasing in which a suitable transformer for exciting the lamps 41 may be housed, and rendered accessible through the door 82.
In Figure 4 of the drawings, we have shown the casing 11 and the louvres '71 as being formed of wood, with the entire back of the casing removable to provide access to the lamps 41 and transformer 43, while in Figures 5 and 6, the louvres and easing are formed of sheet metal as in the device illustrated in Figure 2 of the drawings.
In Figures 7, 8 and 9, we have shown a sign embodying the general construction illustrated in Figures 3 through '7 but having the illuminating devices arranged to produce spaced sources of light 83 along a light panel with the louvres, the louvres being alternately imperforate louvres 85 and louvres 8'7 perforated as at 89 to form designs or characters and the light sources 83 being arranged immediately adjacent the perforated louvres in position to cast rays of light 91 through the perforations 89, onto the portions of the imperforate louvre 85, whichare visible from the front of the sign so that the normally faintly illuminated forwardly facing surfaces of the louvres 85 will receive the rays of light 91 in such a way as to create an illuminated design 93 cor-' responding to the configuration of the cut-out portions 89. In this way, the background upon which the characters 51 of the sign are displayed may also carry faintly illuminated designs or messages which are adapted, in conjunction with the letters of the main sign to furnish an advertising feature.
The details of our construction are, of course, optional and we do not wish to limit our invention to the particular material employed and to the constructions, which we have shown for the purpose of illustrating our invention, since numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention or sacrificing any of its attendant advantages; the forms hereinbefore disclosed being preferred embodiments for' the purpose of illustrating our invention.
