.1 Thisinvention relates to a liquid burning light and particularly to .a candle-like structure adapted to burn liquid fuel, suchas keroseneand the like. I .It .is an object of this invention to produce a new and improved device for producing light fromburnable liquids andhaving novel features of construction, arrangement and operation providing for greater safety, uniformburning, and adapted .for "conveyance fromplace to place without .lossrof fluid or exposure to dangers Another object is to produce a liquid burning light which is non-breakable, strong, simple in construction and operation, andhas-the appearance of a candle in the mounted position whether burning or not.

.Moreparticularly, it is an object of this invention to ,produce'an illuminating device .fabricated of. non-breakable materials with a chamber for receiving a liquid fuel and having one or more additional features including a ventlfor neutralizing pressures within the chamber, insulating means protecting the materials from the heat of the flame, a cover member for preventing the loss of burnable liquid or fumes frompthe chamber and simulating a portion of the candle-like structure when in the mounted position, and means for adjusting the flame without extinguishing same.

These. and other objects and advantages of this invention will hereinafter appear and for purposes of illustration but not o'f'lim'itation, an embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is .a sectional elevational view ofv the device .shown in Figure 2, with the sealing-cap member in-place;

Figure 2 is an elevational view of the liquid burning device shown in the form like structure; and

Figure .3 is a sectional view taken alongthe line *3-'3-of Figure 1.

Referring now to the drawings, N] indicates a tubular casing having an illuminating chamber H open at one end where it is internally screw threaded. The chamber serves as a container for burnable fluid l2, such as the hydrocarbon oils and liquids derived from petroleum, coal and agricultural products, alcohol such as wood alcohol, and the like. The outer wall l3 of the casing is inwardly tapered from the base I to simulate the body portion of a candle, while the base portion I4 is also tapered inwardly and seats in the well of a candelabra l5 or other supporting base, For example, the casing may be positioned of a candle- ,1 3 Claims; (01. (iv-s5) in a socket 'l 6 rigid with a ground 'engaging'spike H, as illustrated in Figure 1' of the drawings; enabling the illuminating deviceto' beusedoutdoors for various purposes.

The 'burnable liquid is introduced through the open end of the chamber which may be sealed by a closure 18 having an externall threaded shank 19 depending from the 'curvilinearbody portion and adapted to be threaded in the open endof the casing I'll. The "closure is provided withja central opening 20through which'af'wick' 21 is threaded. The inner portion of the wick extends substantiall 'through the chamber 'll 'to contact the burnable liquid contained thereinand the outer end of the wick extends slightlybeyond the external face of the closure for purposes. of ignition;

In the past, liquid burning devices havejbeen constructed of such fluid impervious materials'as glass and metal. When glass is used; loss :oiten results from mere impact and great .harm can result when such destruction. occurs while the device is ignited, for the. danger of initiating -a fire and endangering life and limb, is ever present. Metal offers little improvementfor thehigh heat transfer of metallic substances present the danger of overheating the casing to the extent that theburnable fluids are volatilized and forced fromithe chamber, andas such are. dangerous. Metallic material also requires constant cleaning and, with both metal and. glass, it is vdifficult to simulate the waxy appearance of the ordinary candle. 1 i

important ,partof. this invention is directed to the. manufacture of the casing and closure of plastic materials .of the thermosetting or. thermoplastic type. These materials, which may be selected. tobe impervious to the contained liquid, are considered relatively non-breakable and are characterized by low heat conductivity so that. the dangers-inherentof glass or metal are obviated. In addition, the materials themselves are readily compounded for a predetermined color or appearance and readily formable to desired shapes.

However, these plastic materials are heat sensitive, that is they are decomposed at elevated temperatures, and in order to protect the plastic materials from the heat of the flame, I provide a tubular heat insulating member 22 which tightly fits into the central opening of the closure, so as to be rigid therewith and receives the wick 2| which is longitudinally shiftable relative thereto. One end portion of the tubular member extends beyond the outer face of the closure and efieqw tively functions as a heat barrier. In specific application, the heat insulating member may be formed of transite, an asbestos filled compound, or other similar composition which in.

relatively non-volatile oil, disappearance of the liquid by burning causes a vacuum within the V chamber. This prevents uniform movement of the liquid up the wick with the result that a flicking light is produced, which is most disturbing. And then again, when a very volatile liquid is used, variations of pressure within the chamber results from increases and decreases in temperature.' I alleviate the variation in internal pressures by providing a' vent, which may be in the form of an aperture 23 through the closure, for establishing communication between the chamber and the outside atmosphere.

Further improvements result from the means for longitudinally adjusting the wick without extinguishing the flame or handling the wick. For this purpose, I provide an opening 24 extending laterallythrough the tubular insulating member 22 and in axial alignment with the opening 23, through the closure. Through these aligned openings a tool, in the form of a pin or needle, may be inserted and moved to efiect longitudinal adjusting movements of the wick relative to the insulating member.

I further provide a cap member 25 for use with the device when not in use. The cap member is of conical construction, the open ended base portion of which is adapted to seat on the annular flange 26 formed between the closure [8 and the casing I0. The outer wall of the cap member 25 is formed to be coextensive with the outer wall casing 13 so as to appear, when assembled, as a unitary candle-like structure. A central opening 21 in the upper end of the cap member 25 is provided with a short length of wick 28 and when the cap is positioned the entire assembly gives the appearance of an ordinary non-burning candle. The cap member further functions to seal the vent 23 and the device so that the escape of fiunes or liquids from the chamber during periods of non-use is effectively prevented.

From the description, it is apparent that I have invented a liquid burning light which appears as a, candle and has the cardinal features of safety during the periods of use or non-use; means for equalizing pressure within the chamher so as to provide for uniform operation; means for'protecting the device from the effects of heat generated by the flame; means for adjusting the wick without extinguishing the flame; and finally', means for sealing off the various openings in th'e'chamber containing the burnable fluids so that the device maybe stored or carried about 4 without the dangerous emission or loss of inflammable fumes or fluids.

It is to be understood that numerous changes in the details of construction, arrangement and operation may be effected without departing from the spirit of the invention, especially as defined in the following claims.

What I claim is:

1. A liquid burning light comprising a casing having a'cl'iamber therein for receivingthe burnable fluid, an apertured closure operatively engaging said casing for sealing said chamber, said casing and closure being formed of plastic material and shaped to simulate a candle-like structure, a wick extending through said aperture and into said chamber, a heat insulating member rigid with said closure and separating said Wick from said closure, aligned openings through said closure;' and heat insulating member for establishing communication between said chamber and the outside atmosphere, and a cap member concealing said closure and sealing said vent and Wick from the atmosphere. 2. A liquid burning light as claimed in claim 1 in which the closure is of smaller diameter than the engaged portion of the casing to provide an annularlshoulder externally of the closure when in the mounted position, and the cap member is contoured to rest on the shoulder with its sides flush with the adjacent side walls of the casing.

3. A liquid burning light comprising a casing having a chamber therein for receiving the burnable fluid, an apertured closure operatively engaging said casing for sealing said chamber, said casing and closure being formed of rigid material impervious to the burnable fluid and shaped to simulate a candle-like structure, a wick extending through said aperture and into said chamber, 'a heat insulating member rigid with said closure and separating said wick from said closure, aligned openings through said closure and heat insulating member for establishing communica-- tion between said chamber and the outside atmosphere, and a cap member concealing said closure and sealing said vent and wick from the atmosphere.
