1Claim.
My present invention is an improved neon gas illuminating apparatus primarily intended for utilization in advertising devices.
In the present use of neon gas for illuminating and advertising, it is customary and indeed essential to employ tubular devices to withstand the very considerable pressure on the exterior of the glass containing the neon gas because of the vacuum within the tube as well also to conserve the gas and eifect the illumination.
In my present invention I have developed a novel and efficient method of utilizing the highly advantageous vand desirous neon gas illumination in containers other than tubular, which may also be employed in combination with the usual neon tube illuminants where desired. Thus, I am enabled to produce attractive designs in a large, extensive, and wide variety of designs, forms, and combinations permitting the utilization of contrasting colors of neon gas, particularly important in advertising illumination although equally valuable for illuminating purposes broadly considered.
A feature of my invention is that I can prepare relatively large panels of neon gas illuminating capacity and, in fact, might fabricate standard types and sizes for border illumination as well as the masses of colors produced by a panel or the like, and I may build up series or sets of varying designs in combination with Varying contrasting colored designs by means of my present invention.
From a construction as well as an advertising standpoint, this enables me to greatly simplify the expense in such panel or panel-like construction for neon gas illumination and, therefore, permits the same to be used commercially at relatively slight expense.
In carrying out my present invention I provide various shaped and sized panels constructed and arranged to resist the outside pressure and to contain either neon gas as the illuminant or neon tubes thereon, or a combination of both, thus giving an attractive illuminating and advertising feature not heretofore possible Where neon tubes only were used. I
Thus, for example, I may have a relatively large glass panel showing a neon gas border in a plurality of colors, or a plurality of borders, with lettering, words, or the like shown in the center by utilizing my invention, and a standard type of neon tube for the center lettering. This also gives the benefit of contrasting coloring where desired.
I am enabled to make these panels of relatively large size by arching the exterior walls to resist the atmospheric pressure, and may also form partitions therein to give pressure-resisting structure within the panel, which partitions will also serve to support contrasting and neon gas for illuminating effects.'
Further features, details, and important advantages will be hereinafter more fully pointed out and claimed.

Fig. 20 is a diagrammatic view illustrating a general design of paneling by reinforcing to contain contrasting colors;
Fig. 21 is a small diagrammatic view of a typical container, and
Fig. 22 is an enlarged cross-sectional view of the same.
Referring to the drawings, Figs. 1 and 2 illustrate a typical embodiment of the invention in a simple construction. This comprises the vacuum vglass container designated generally at I, and having substantially lflat sides 2, 2, ends 4 4, and convex or curved, arc-shaped sides 5 5. This construction enables the container I to permit the air to be exhausted, neon gas supplied therein, the vacuum seal closing it, and electric conducting wires 1 1 led through the glass container at appropriate points, viz., the ends in Fig. 1, terminating in ignlting electrodes 8 8 which ignite the neon gas and effect the illumination. The arc-shaped contour of the relatively broad surfaces 5 5 serves to impart appropriate strength to withstand the atmospheric pressure as the neon gas contained within gives practically no support, and the differential between the atmospheric pressure and the vacuum within is thus withstood by the arc-shaped contour.
In the form shown in Fig. 3, I have illustrated a typical type of bulls-eye construction, wherein the rim I and bulls-eye plate I2 withstand the pressure, a duplicate being on the back of same, or a suiliciently heavy plate of glass to stand up to the strain involved proportionally to the extent of the exterior pressure generated bythe area within the rim I0.
In Figs. 4.and I have illustrated a plate or panel I5 of substantial area having its ends I6 40 of suitable depth and the curved or convex panel surfaces |8 as shown,v which are, furthermore,
reinforced by interior partitions 28, thus producing a greatly strengthened structure as well as providing a series of recesses or chambers 2|, 22, 45 23, 24, and 25, as herein illustrated for example,
each of which may contain different or contrasting colored neon gas, and hence lights, each rendered incandescent by the igniting electrodes 8 8 for each division.
50 In Fig. 6 I have illustrated a still further modi'- flcation wherein the panel designated vgenerally at 30 has exterior partitions 3| and 82 dividing the areas 33, 34, and 35 into different and separate compartments which may contain differing or contrasting neon gas each rendered incandescent by the appropriate pair of ignlting electrodes 8 8, as will be readily understood. Preferably,
I also form the broad panel surfaces, even with these reinforcing partitions, with curved or arcshaped form, as shown at 36 and 81.
In Fig. 8 I have illustrated ,a further form of panel 48, wherein the partition 4I is in the form of a border, giving a borderlike recess 42 with its pair of ignlting electrodes 8 8. On
the outside of one of the curved surfaces 43 or 44 is provided an illuminating neon tube 45 with its separate wires 1 1, and also on the outside of the surface 44 is the lettering or sign in the form of a separate tube 48 separately illumined by its pair of wires and ignlting electrodes therein, and containing any contrasting neon gas clesired or appropriate for the design accorded by the lbackground and border construction illustrated.
In Figs. 10 and 11 I have illustrated some-l what a special design of border tubes as indi- -cated at 68, and the corner or molding-like tube 5| to show the facility with which my presentv invention cooperates with a wide variety of designs. parts, panels, plates, tubes. and the like by which original and special designs can be readily assembled or built up. of suitable length and extending to fit in an'd be secured to the corners of the panel.
A further modication of my present invention is illustrated in Figs. l2 and 13, wherein I have formed my convex orare-shaped strengthening structure entirely independently of ends, sides, or edge portions. An important advantage and feature of this concave-convex exterior surface in a neon panel is that it affords ample room therewithin to -receive the neon gas in suilicient quantities for illumination and may also receive a separate neon tube containing contrasting color.
In carrying out this feature of my invention, Fig. 12 illustrates a neon tube panel 60 formed entirely by the convex plates 6| and 62 meeting at their edges 63 in any form or design desired as round, square, oblong, rectangular, or otherrwise, and providing space 64 therewithin to receive a supply. of neon gas and ignlting electrodes 8 8, and also a separate neon tube 66 which may be filled with contrasting colored gas and with its separate ignlting electrodes and cur- Y rent-conducting wires, as will be readily appreelated.
In Figs. 14 and 15 I illustrate a still further modification wherein the panel 10 is of a construction substantially slmilar to that of Figs. 1 and 2 but has formed on the outside of one of the curved surfaces 1I convex and opaque or transparent glass lettering 12, relying upon the background of the neon illuminating gas contained within the interior 14 of `the panel 18 to effect the name. advertising, or other feature desired.
In Figs. 16 and 17 a similar construction is shown wherein the container 11 has the fixed glass lettering 18 within the surface of the convex sides 19 of the panel 11, as will be readily appreciated on referring to the drawings. 'I'his gives a smooth exterior surface and preserves the lettering 18 from damage or accidental displacement.
In Figs. 18 and 19 I have illustrated a still further modication wherein the panel 88 is formed with a partition 8|, here shown as in the form of a border, and with a series or set of curve, convex, or arc surfaces from the ends 82 to the partition 8|, as shown at 84,' and thence between the boundaries of the partition 8|, as shown at and 86. In this construction, also, the convex glass lettering` may bel used or the separate ne'on tubes either outside or inside, the form being herein illustrated showing the neon tube 88 contained within the inner sidel of the central cham` ber and with its separate wires 1 1 extending thereto.
In Fig. 20 a still further modification is shown wherein the panel is provided with a large Figs. 21 and 22 illustrate a still further form N with convex surfaces IDI and i0! meeting entirely around their edges without any substantial straight ends or edge portions, such as 2-2 y 5 of Figs. 1 and 2, and |6I6 of Fig. 5; Fig. 22 ila wide range of design and facility of combina` tion, and, so far as I am advised, it is broadly new i to devise a panel or the lilie of substantial area for use with neon gas illumination, and I wish to claim this feature broadly.
My provision of reinforcing partitions and of reinforcing convex or arc construction enables the use of neon gas illumination in a greater range of utility than has heretofore been possible 20 when simply employing neon tubes.
Furthermore, the facility of design and cooperation with neon tubes is a most important feature, and I wish to claim such combination broadly herein.
I claim:
The improved method of neon gas illumination, which consists in providing non-tubular 5 panel-like containers of relatively large area and presenting a substantially rectangular appearance of greater length and breadth than depth, constructing said panel-like containers with a convex exterior surface in combination with a plurality l0 of integral partitions, dividing said panel-like containers into separate and complete gas-containing .portions of the panel-like containers, the partitions and convex exterior cooperating to withstand atmospheric pressure, each separated secl5 tion being provided with current-conducting means to illuminate gas contained therein, whereby a complete panel-like neon gas illuminating device is provided with the combined area of all partitioned sections presenting a panel-like appearance.
