PORTABLE GAS-LIGHTING OUTFIT.

Specification of Letters Patent.

Application filed January 22, 1918. Serial No. 213,121.

T 0 all whom it may concern:

Be it known that I, CHARLES E. VER- HUNCE', a citizen of the United States, and a resident of Chicago, in the county of Cook and State oflllinois, have invented certain new and useful Improvements in Portable Gas-Lighting Outfits, of which the following is a full, clear and exact description.

The invention relates to portable gas lighting outfits.

One object of the invention s to provide an improved portable gas lamp which is adapted for service in a tent or other struc ture. V In lighting outfits of this character, it is desirable to provide a lamp which may be supported over head without danger of burning the tent or structure in which the outfit is installed. To meet this requ1re- 'ment, the invention includes a portable gas lamp which is organized and supported so as to overcome any danger of a conflagration. I

In attaining this" object, the lamp is provided with one or more supply connections at one side thereof, as distinguished from the usual centralcombined supply pipe and support. This provision makes it possible to use flexible'tubing to supply gas to the lamp and to keep the tubing out of the upward path of the heat or products of combustion from the burner; In conjunction with the side gas connection, a flexib le metallic support, such as a chain which is noninflammable, is utilized to support the lamp in desired position from the ridge pole of the tent or other support of the structure in which the lamp is installed. A further object of the invention is to provide an improved construction of gas lamp in which there is no flame 1n the cen tral portion of the lamp, so that there wlll be a current of air flowing upwardly which serves to quickly cool the products of combustion, the burners being circumferen-tially disposed within and around the reflector.

Another object of the invention is to providean improved reflector and support for a portable gas lamp which are slidably connected so that the support may he slipped into the reflector for convenience 111 packingthe outfit. It will be understood that it is the desideratum in lighting outfits of this character to pack the parts in a small area forconvenience in transportation.

Lastly, the invention designs to provide a portable gas lamp which is simple in con- 1 trated as installed in a hospital tent a and comprisesaportable gas tank 6 and a flexible tube 0 which is suitably connectedtothe tank and controlled by a suitable valve as well understood in the art, to supply gas to a portable lampsuspended from the top of the tent or structure.

The improved lamp comprises a conoidal reflector 7. Around the lower margin of the reflector, there isdispo'sed a hollow ring 8, to which a metallic nipple 9 is connected by means of a valve 10, to supply gas to the ring 8 from the flexible tube 0. Ring 8 is connected to the lower margin of the reflector 7 by slotted lugs or plates 13 and thumb-screws 14:. For convenience in packing and assembling. the tube 0 is detachably connected to the nipple 9 by a coupling 11. A. series of burners 12 extend inwardly and slightly upwardly from the inside of the hollow ring'8 and below the lower margin of the reflector. The reflector is preferably formed ofsheet metal and has an opening 7 in its top, the metal being reverted as at 15 to stiffenthe upper portion of the reflector. A hood 16 is slidably mounted in the top ottlhe reflector and comprises a cylindrical metal body 16 whichis provided with outwardly extending struckup tongues 17 which serve as stops upon which the reflector rests and by which it is supported from the hood and a bowl or top-shade 18 which is secured in fixed andspaced relation to the top of the body 16 by lugs 19 which are riveted to the cowl and said body. The body 16 is also provided with outlet openings 20 which are formed by bending tongues 21 inwardly. v The products of combustion escape through these openings 20 and the Patented May 24, 1921. p

space between the body 16 and cowl 18. The tongues 21 and cowl l8 serve to deflect the heat laterally so there will be no strong upward draft that will endanger the structure in which the lamp is installed. A metallic chain 22 is secured to an eye 23 which is socured in the cowl l8 and is adapted to be looped around the ridge pole of a tent or any other convenient support and is provided with a hook 24 adapted to pass into the eye 23 to support the lamp in desired overiead position. v

In some instances, it is desirable to supply an additional lamp or burner from the supply hose 0. For example, a small burner to illuminate the entrance to the tent and for this purpose a metallic nipple 25 is secured to thehollow ring 8 diametrically opposite to the nipple 9 and a semi-circular supply pipe is connected to these nipples to conduct gas to nipple '25 from nipple 9. An auxiliary flexible tube section cl is connected to the nipple 25 by a detachable coupling26 and this flexibletube is suitably connected to the auxiliary'burner 6. The supply of gas through the tube (Z is controlled by a valve 6 at the burner e. The flexible tubes are supported beneath the ridge-pole by .and be deflected laterally to breakup any strong draft which might cause ignition of the structure in which the lamp is installed or of the flexible tubing.

The invention thus exemplifies a gas burner in which provision is made for a central current of cool air tocool the prod nets of combustion and prevent a strong upward draft to apoint above the lamp.

Also one in which shadows are avoided.

In a portable lighting outfit, it is desirable that the parts of the lamp should be susceptible of being packed into a small container, and the slidable connection between the body 16 and reflector 7 exemplifies a portable gas lamp by which the hood may he slipped downwardly into the reflector, as indicated by'dotted lines in Fig. 5. As a result, this construction can be packed in a cylindrical box or containerapproximately the height of the reflector, in lieu of the 7 combined eflective'height of the hood and reflector; The coil of flexible tubing may .be disposed-, in the box around the upper portion of the reflector.

The invention is not to be understood as restricted to the details set forth, since these may be modified within thescope' of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1.111 a portable gas lighting outfit, the combination of a reflector having an open bottom, one ormore, gas burners adjacent the bottom of the reflector, a gas supplying connection "for the burners, and a hood sliding a perforated cylindrical body and a cowl.
