United States Patent 3,063,278 GAS LAMP Richard F. Van Tubergen and Charles A. Mueller, Santa Fe, N. Mex., assignors to Breese Industries, Inc., Santa Fe, N. Mex., a corporation of Delaware Filed June 2, 1959, Ser. No. 817,573

4 Claims. (Cl. 67-87) This invention relates to gas lamps of the class employing bottled gas as fuel.

When operating ornamental and other gas lamps from high pressure bottled gas two difficult problems are presented. First, since the valve adjustments required to maintain the flame at the desired level are extremely minute, thermal expansion of the valve with continued operation of the lamp necessarily affects the valve, usually by closing it, so that frequent and inconvenient adjustments are required for satisfactory operation of the lamp.

Secondly, the hydrocarbon constituents of the gas are cracked by the high temperatures. prevailing in the burner with resultant formation of gums and tars. These also interfere with proper functioning of the lamp, preventing maintenance of the desired low, flickering flame.

'It is the general object of the present invention to provide a gas lamp and combination valve and burner therefor which overcomes the foregoing objections and which, in addition, is conveniently operated from commercial bottled gas containers.

Themanner in which the above and other objects of this invention are accomplished will beapparent from the accompanying specification and claims considered together with the drawings -wherein:

FIG. 1 is a view in elevation of the herein described gas lamp with part of the illuminating section broken away to show its construction; and

FIG. 2*is 'a view in elevation of the lamp base, with valve and burner assembly in section, illustrating the manner of operation of the same and also the manner in which it is coupled to a bottled gas container.

Broadly stated, the gas lamp of our invention comprises a hollow base dimensioned to receive a bottled gas container. A combustion chamber is supported on the base and communicates with its interior. A vented illuminating section is mounted on the combustion chamber. Valve controlled burner means are connected to the gas container for producing the desired illuminating flame in the illuminating section of the lamp.

Considering the foregoing in greater detail and with particular reference to the drawings:

The lamp of our invention is provided with a base which is ornamental in appearance, imparts stability to the lamp and affords easy access to the interior for inserting and removing bottled gas containers as required. Thus it includes an upper section 12, the lower margin of which is provided with a flange 14 and inwardly directed tabs 16. These releasably interengage a flange 18 on the upper margin of a lower base section 20. A foot 22 is fixed to the bottom of the latter. This rests flat on a table or other supporting surface.

Base 10 is dimensioned to receive a commercial bottled gas container 24 of the indicated contour, having a neck 26 and a rubber seal 28 adapted to be penetrated by a spur or needle for gaining access to its gaseous contents.

The upper section 12 of base 10 is provided with a neck 30 from which extends spaced locking projections 32. These releasably interlock the base and a combustion chamber 34 provided with slots 36 which engage projections 32 and provide rotary interengaging means for securing the two members together. Screened vents 38 introduce air into the chamber.

glass 48.

A top 50 formed of metal plates 52 and reinforcing members 54 is fastened to extensions 56 of frame members 46 by means of metal screws 58. It supports a vented cap piece 60.

The construction of the valve and burner means employed in the presently described lamp is particularly evident in FIG. 2. The valve means comprises a body 62 having therethrough a passageway 64 which communicates with a hollow needle 66. The latter extends downwardly from the body and penetrates the rubber seal 28 of bottled gas container 24, the seal being dimensioned for reception in a recess 68 in the underside of the valve body.

Means are provided for releasably securing the valve body to the top of lamp base 10. Such means may comprise, for example, a threaded extension of the valve body which penetrates an opening in the top of the base and is engaged by means of a nut 70 in the interior thereof. I

. An extension 72 extends upwardly from valve body 62. It is formed with an annular recess dimensioned to receive a rubber O-ring 7'4, with an intermediate threaded section 76, and with an upper terminal needle section 78. A case 80, which includes the burner nozzle, is superimposed over body extension 72. The case is hollow and is formed with an interiorly threaded, enlarged nut justment remains constant over long periods of lamp use.

The passageway 64 continues upwardly through extension 72, as shown by the dotted lines 64a, said passageway terminating in a transverse passageway 89 through the needle section 78 in order to introduce the gas into the chamber 90 defined by the portion of hollow case 80 surrounding needle section 78. The gas flows from chamber through passageway 91 into chamber 92 wherein it is ignited. The needle section 78 controls the flow of the gas through passageway 91.

To operate the lamp, base sections 12, 14 are separated :by twisting them relative to each other until lugs 16 become disengaged. The bottled gas container 24 is inserted into top section 12, needle 66 penetrating rubber sealing cap 28. Bottom section 20 of the base then is replaced and twisted to lock it to the upper section.

Burner nozzle 80 is preheated for from 3045 seconds by holding it over an open flame such as that afforded by the burning of a wooden match. Nut 82, which controls the relative positions of needle 78 and nozzle 86 then is barely cracked open and the burner ignited.

The burner is allowed to burn for from 1-2 minutes with the flame approximately 3 inches high. It now is adjusted by means of nut 82 to the desired operating height which generally is from 1 to 1 /2 inches. The illuminating section 44 of the lamp then is locked on by means of locking projections 32, whereupon the lamp will burn without need of further adjustment for many hours.

It is to be understood that the form of our invention, herewith shown and described, is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be re- 3 sorted to without departing from the spirit of our invention, or the scope of the siibjoined claims.
