5 Claims, 5 Drawing Figures PATENTEUHARZOIQYS JAMES 0. REESE INVENTOI? M 7 A TTO/PNEVS PORTABLE LAMP BACKGROUND OF THE INVENTION The invention relates to a portable lighting device and more particularly to a portable gas lamp having particular utility as an ornamental accessory for patios, terraces, gardens and the like.

The prior art includes numerous types of so-called tiki torches, including wooden torches, oil burners, and fixed jets of natural gas.

It is well recognized that a use of wooden torches is impractical, for most purposes, while oil burners and the like particularly are susceptible to smudging and contaminating the atmosphere, due to a release of large quantities of unburned fuel, while gas jets connected with a source of natural gas often are impractical, due to an inherent lack of portability.

Consequently, there currently exists a need for a practical tiki torch of a portable nature which can be readily and efficiently employed as an ornamental accessory for illuminating patios, terraces, gardens and the like.

OBJECTS AND SUMMARY OF THE INVENTION It is therefore an object of the instant invention to provide an improved tiki torch.

It is another object to provide an improved tiki torch which, in operation, is efficient.

It is another object to provide an improved lighting device for use as an ornamental accessory in lighting patios, gardens, terraces and the like.

It is another object to provide a self-contained, portable gas lamp adapted to be implanted at selected locations for illuminating patios, gardens, terraces and the like.

It is another object to provide an improved, self-contained portable lamp for use in providing an illuminating flame of burning gas for illuminating selected areas.

These and other objects and advantages of the instant invention are achieved through a use of a portable lighting device including a pillar suited to be implanted at selected locations, in the soil of patios, gardens, terraces and the like, having an ornamental head surmounting the pillar and a gas burner suspended within the pillar for supplying an effervescent fuel to the burner, whereby the device readily is adaptable for use as an ornamental lighting accessory.

BRIEF DESCRIPTION OF THE DRAWING Fl l.

%IG. 4 is a sectional plan view, taken generally along lin 44 of FIG. 2.

FIG. 5 is a sectional plan view taken generally along line 5-5 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings wherein like'reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 1 a

portable lamp, generally designated 10, which embodies the principles of the instant invention.

The lamp 10 includes a pillar l2 surmounted by an ornamental head 14 terminating in an acuminate pedestal 16 which facilitates implanting the pillar 12 of the lamp 10 in the soil of patios, terraces, gardens and the like for facilitating its use as an ornamental device of the type frequently referred to as a tiki torch.

The pillar 12 is fabricated from thin-wall tubular steel stock and is of a suitable length. The head 14 is of any ornamental design of any selected configuration, and terminates in a tubular skirt 18 which is telescoped onto the upper portion, designated 20, of the pillar 12. Hence, the ornamental head 14 is supported by the pillar 12 as the pillar is supported in the soil of the selected area in which the pedestal 16 is embedded.

Within the skirt 18 there is fixed a transverse support bar 22. This bar is welded or otherwise secured in place within the skirt 18 and includes an opening, not designated, coaxially aligned with the pillar 12. Within this opening there is seated an externally screwthreaded nipple 24 to which a burner 26 is threadedly coupled.

The burner 26, in practice, is a pipe cap having a plurality of ports 28 extending radially therethrough for defining an annular array of gas jets communicating with the nipple 24. As a practical matter, a pair of stop nuts, not shown, is screw-threaded onto the nipple 24 for securing the nipple to the support bar 22, however, the particular manner in which the nipple 24 is mounted on the support bar 22 is a matter of convenience and can be varied as desired.

Depending from the nipple 24 there is a screwthreaded reducer 30 which serves to couple the burner 26 with a gas supply circuit, generally designated 32. The circuit 32 includes a length of tubular conduit 34 from which is suspended a bottle 36 of compressed gas, normally maintained in a liquid phase. The particular type of gas employed is a matter of convenience and since such bottles are commercially available, a detailed description is omitted in the interest of brevity.

To the bottle 36 there is coupled a flow control, manipulatable valve 38, which, in turn, is united with the conduit 34 through a suitable, internally screwthreaded sleeve 40 received by a screw-threaded fitting 42 provided for the flow control valve 38.

For reasons which are readily apparent, there is provided an access opening 44, immediately adjacent the valve 38, which accommodates a manipulation of the valve. Of course, where so desired a cover plate, not shown, can be employed in closing the access opening 44.

In view of the foregoing, it is to be understood that the lamp 10 is assembled with the head 14 removed from'the pillar 12. With the pillar l2 and head 14 disassociated, the gas supply circuit 32 is assembled and coupled with the burner 26, whereupon the head 14 is telescoped onto the uppermost end of the pillar 12 as the bottle 36 is caused to descend into the tubular interior of the pillar 12. When thus assembled, the lamp is readied for use.

OPERATION It is believed that in view of the foregoing description, the operation of the device will be readily understood and it will be briefly reviewed at this point.

With the device assembled in the manner hereinbefore described, the lamp l manually is driven into the soil of an area to be illuminated, such as may be found in patios, terraces, gardens and the like. When so embedded, the pillar 12 remains upright. An operator gains access to the valve 38, by reaching through the access opening 44, and manipulates the valve while simultaneously applying a flame to the burner 26, whereupon ignition of gas delivered thereto from the bottle 36 through the valve 38 occurs. By manipulating the flow control valve 38, the height of the resulting flame is varied.

Of course, the particular configuration and design of the ornamental head 14 serves to enhance the esthetie quality of the radiation produced by the illuminating gas flame, and can be varied as desired.

The flame is extinguished simply by closing the valve 38. In instances where it is found desirable to provide a re-fill bottle 36, the bottle is disassociated from the conduit 34 at the nipple 24, and replaced with a commercially available re-fill bottle of a selected capacity. Similarly, changing of the head 14 is accommodated.

In view of the foregoing, it should readily be apparent that the lamp of the instant invention provides a practical device for use as an ornamental accessory in illuminating patios, terraces, gardens and the like.

Although the invention has been herein shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the illustrative details disclosed.
