HEAT AND LIGHT CONCENTRATING HOLDER FOR ILLUMINA'IED DECORATIVE LIGHTING DEVICES Filed June 9, 1945 L. BARNETT INVENTORQ Patented Nov. 16, 1948 HEAT AND LIGHT CONCENTRATING HOLDER FOR ILLUMINATED DECORA- TIVE LIGHTING DEVICES Louis Barnett, Brooklyn, N. Y., assignor to Raylite Electric Corp, Long Island City, N. Y., a corporation of New York Application June 9, 1945, Serial No. 598,568

Claims. 1

This invention relates to improvements in illuminated ornamental devices and more particularly is directed to a heat and light concentrating holder means for confining heat and projecting light passing from an incandescent lamp to a liquid column for forming an illuminated vapor bubbling or unbroken stream display efiect, such as used for trimmin Christmas trees or decorative lighting, signs or the like.

Amon the objects of the invention is to generally improve devices of the character described which shall be exceedingly simple in construction, of few parts, which shall be easy to assemble in effective position, which shall be cheap to manufacture, and which shall be practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown various possible illustrative embodiments of this invention:

Fig. l is a front elevational view of an assembled unit of a Christmas tree lighting unit, shown partly broken away to expose the interior, constructed to embody the invention.

Figs. 2 and 3 are cross sectional views taken on lines 2-2 and 33, respectively, in Fig. 1, and

Fig, 4 is a perspective view, showing the improved heat and light concentrating holder removed from the lighting unit.

Referring in detail to the drawing, Ill denotes an illuminated ornamental device adapted to be used to trim a Christmas tree or the like, having incorporated in the assembly thereof a heat and 7 light concentrating holder member iI constructed to embody the invention.

Said holder member I l as seen in Figs. 1 and 4, comprises a sleeve connector supporting in vertically upright position, a transparent tube body of glass or other translucent material designated generally as i2, said tube body i2 having an integral closed lower or bottom end I2a and sealed top end I212. The closed bottom end I2a, is fitted into the upper end Ha of said holder member II, so that the lower or bottom tube end I2a is firmly supported in close proximity to a bulb Eta of an incandescent lamp I3, the lamp bulb 53a being fitted up into the lower end Nb of said holder member II thereby providing a relatively firm interconnecting support or rigid coupling.

The lamp I3 as here shown is mounted in one electric socket lb of a Christmas tree lighting outfit of a well understood construction (not shown).

The tube body l2 may contain a readily vola- 2 V tilizable liquid I4, such as other or wood alcoho but preferably a transluscent liquid which has a like relatively normal low boiling point but which is non-inflammable. The liquid I4 may be placed in the tube body I2 through the top end I21) thereof before fusing the latter for hermetically sealing in liquid I4 therein as shown in Fig, 1. The space I5 above the liquid 14 in the tube body l2 may be evacuated before said tube top end I2b is sealed to permit lowering the boiling point normally required for the liquid l4. Said space I5 constitutes a condensing and heat dissipating means.

As seen from Fig. l, the invention is shown incorporated in the assembly of the ornamental illuminated device II] as above described, said sleeve connecting holder member II being preferably made of any suitable material having light conducting properties of a high degree efficiency as for example quartz, or any well known molded plastic having similar characteristics, such as Lucite. The lower end lib of holder member I I may be provided with spaced wing sections IIc which are inwardly bent to have rim edge surfaces IId positioned in horizontal alignment with filament I3b in lamp bulb I311. The upper end I la, of said holder member I I may be formed or terminate with integral resilient spaced gripper portions I Ie which may also be inwardly bent preferably in suitable angular relation to the axis of the tube body I2 and liquid column I4 so that light beams from the glowing lamp filament [3b which are caught bysaid edges I Id are transmitted longitudinally through the holder II and projected from terminating rim edge surfaces II of gripper portions He into the liquid column M, as is clear from Fig. 1.

In practising the invention, assume an electric socket I6 is provided or arranged for decorative display lighting purposes and connected to a suitable power supply source (not shown) in the well understood manner for lighting the lamp I3. Heat and light radiated from the lamp filament [3b may be made effective to cause the generating of vapor I'l either in form of a continuous fiow of bubbles, or in an unbroken stream current through the liquid column I l. The sleeve holder II which mounts the tube body I2 on the lamp bulb I3a serves to guide and confine the heat conducting medium, namely, air therebetween that a minimum of heat producing source will be necessary. The light transmission provided by the improved construction of said sleeve holder II above described, increases the light available by projecting therethrough light beams directly from the lamp filament I3a into the liquid column I4, in addition to light beams from lamp filament I31) which are projected longitudinally the length of theholder II into flowing bubbles or current I! as seen from the exment I3b by two separate paths one of which,

by-passes the bottom tube end I20; and is transmitted through holder member II is particularly desirable when a bubble or current formingmeans forms an obstruction of the direct rays from the lamp filament I3b, or is opaque to the direct passage of light in which case substantially all the illumination to said bubble or current flow I! is circuited through said sleeve member II as described above and is clearly'shown in the draw ing.

By coloring the material forming sleeve mem- :ber II a wide range of color efiects are made available beside the variegated lighting, produced at and around the openings in the regions of the spaced gripper portions I Ia and spaced wing sections IIc.

It is also to be understood that holder member II may be made to conform to any requirement of design desired such as of straight lin contour or of bulbous character. This feature is made possible because the light conducting ma- 7 terial forms a path through said holder member I I and is not affected by the shape thereof intermediate rim edge surfaces lI f of gripper portions He and rim edge surfaces I Id of wing sections I I0.

It also is contemplated in practising the invention described herein to apply same to holder fitting such as shown in Patent No. 2,378,934, issued June 26, 1945, to Joseph H. Kloner. In such case the incandescent lamp is mounted at right angles with respect to the tube body, such holder fitting being constructed of molded plastic, as for example Lucite and is formed to transmit light from the lamp filament through the molded plastic material as well as directly through the extension holder supporting the tube body in th same manner as above described for member II.

It is thus seen that there is provided an improved heat and light concentrating holder means :of the character described in which the objects of the invention are achieved and which are well adapted to meet all conditions of practical use.

As various possible embodiments may be made as illustrative and not in a limiting sense.

Having thus described my invention, I claim as 'new and desire to secure by Letters Patent:

1. A device of the character described comprising an elongated sealed transparent tube body partially filled with a liquid column, said body being constructed and arranged to generate activated vapors for producing lighting effects passing through the liquid column on positioning an incandescent lamp having a glowing filament exteriorly at one end of said tube body, and a light transmitting member for supportingly mounting the tube body over said lamp so that heat from said filament is guided and confined to generate said vapors, said member having portions turned toward the filament and tube body to transmit light beams emitted by said filament and for directing same through the tube body and hence into the liquid column for illuminating the activated vapors.

2. A holder of the character described comprising a light transmitting sleeve member for mounting a transparent tube body with a volatile liquid column therein over an incandescent lamp having the filament and for guiding and confining illuminated radiant heat from said filament to generated flowing vapors in said liquid column, portions of said sleeve member being bent to receive direct light from said filament for transmitting same through said member and bent to direct said light into the tube body in addition to illumination received with said guided and confined radiant heat.

3. A device as defined in claim 1 in which said holder member is formed of one piece having a resilient end structure for engaging said ornament and forming said portions.

4. A device of the character described comprising a tubular structure formed of light condensing and guiding material one end of said structure having integral holder means for mounting a decorative ornament containing a vaporizing liquid, the other end of said structure having a portion turned to receive light beams from a glowing heat producing filament for transmission through said structure, said first mentioned end being turned to transmit light beams passing j therethrough into said ornament.

' 5. A device of the character described comprising heat and light concentrator holder member for supportingly mounting an illuminated decorative display ornament over a glowing heat radiat- "ing means, said member having means extending between said heat radiating means to an end of the ornament for confining and guiding heat from said radiating means to a liquid vaporizing region r of said ornament end, and light projecting means for transmitting light from said glowing means in a plurality of paths into said ornament, said light projecting means having portions forming said paths turned toward the glowing means and turned toward said ornament end.
