This invention pertains to improvements in illuminating devices and appliances in which a continuous luminous tube is employed for the purpose of materially increasing the brilliancy and illuminating qualities in connection with illuminated signs, trailic lights, display, decorative, and all other purposes for which this device or appliance may be utilized or employed as an illuminating re or lighting source.

The prime object of this invention is to so construct my improved illuminating device that it will serve to maintain and create a reatly increased illuminating power and 1% hrilliancy over and. above the ordinary illuminating device now usually employed.

Another object of the invention is to provide an illuminating device of any desired shape or contour forming a single unit, and

all composed of a luminous glass tube with a glass reflector having a silvered outer surface, said reflector being integrally secured or united to said tube.

N A further object of the invention is to so form an illuminating device from a continuous tube of luminous glass adapted to contain a suitable illuminary means, such as neon gas, or other illuminating gases, having each terminal end portion of said tube united by a single socket member.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, arrangement, location and combination of the several parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the cla'ms appended hereto, it being understood that slight changes in the precise shape, proportions and minor details of the construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification it will be seen'that:

Figure 13 is a cross-section taken through the tube shown in Fig. 12.

In the embodiment of my. invention as illustrated it will be seen that the numeral as l designates a glass refiecter which is formed into all shapes desired or required, and may be formed from single strips or sheets such as shown in Figs 10 and 11, with each of the side edges thereof preferably united or if preferred the said reflecter may be Formed from a single piece of glass, the rear surface being provided with a silvered coating 2, and upon the upper or outer surface of the refiecter is suitably coiled a glass luminous tube 3, that is filled with neon or other suitably illuminating gases, such as are well lmown in the art of illuminating devices, the inner terminal end l of the glass tube passing through a central opening. formed through 1064 the reflecter, while the outer terminal end 4' of the glass tubing is bent downwardly and inwardly, both of the terminals of the tubing being united by a suitable socket member 5, to which socket member is suitably connected the usual electric wires 6, 6 and electrodes (not shown) for causing the gaseous vapor within the glass tubing to be ignited thereby causing the tubing to impart a brilliant luminous light entirely throughout its length.

It will be understood. that the glass reflecter form is first prepared in any and all suitable shapes desired, after which the glass tubing is suitably placed over the outer surface of the reflecter in such formation as is desired, then the tubing and reflecter are united by annealing, or in any other suitable manner, thereby forming the reflecter and tubing into a single integral illuminating unit.

It will thus be perceived that owing to the peculiar and particular formation of both the luminous tubing and the reflecter, that this type of illuminating device will serve to materially increase the brilliancy and illuminating qualities of the device for all purposes for which it may be employed.

Referring now to Fig. 3 of the drawings it will be seen that a modified form of illuminating device is shown, the numeral 7 indicating another form of reflecter, having a spirally disposed luminous glass tubing 8 surrounding said reflecter with the terminals of the said tubing leading to a socket connection (not shown) for uniting said terminals, and Fig. 4: shows a single letter C showing the dished or curved reflecter member 9 and the glass luminous tubing 10 united thereto forming a single integral unit.

Figs. 5 and 6 show a special type of reflecter 11 intended especially to be used in connection with illuminating devices to be attached to or connected with the ceilings of rooms of all dimensions, Fig. 6 showing the tubing and connections in dotted lines, while Figs. 7 and 8 show in elevation and cross-section a modified form of illuminating device, with a reflecter 12, the tubing being shown in dotted lines Fig. 7.

By reference to Fig. 9 will be seen another modified form of illuminating device of square or rectangular formation showing the reflecting member 13 and the glass luminous tubing 14 in dotted lines, and Fig. 10 shows a portion of the reflecter 15 in plan; Fig. 11 showing a cross-section of said reflecter; Fig. 12 shows in plan a portion of the glass luminous tubing 16 and Fig. 13 shows a crosssection of said tubing.

It will be readily obvious that my improved illuminating device may be formed into any and all of the various shapes and formations desired, and that owing to such formations, in connection with the united glass tubing and reflecting member formed in the manner hereinbefore described, the intensity of the illuminating power will be greatly increased Without increasing the cost for maintaining its illuminating qualities.

Having thus described my invention what I claim and desire to secure by Letters Patent is:
