CARBURETlNG-LAMP.

SPECIFICATION forming part of Letters Patent No. 768,063, dated August 23, 1904.

Application filed August 20, 1903- Serial No. 170,205. (No model.)

To all whom it may concern:

Be it known that I, J osEPH MATON, a citizen of the United States of America, residing at 5 North St. Andrew street, Edinburgh, in

the county of Edinburgh, Scotland, have invented a new and useful Carbureting-Lamp, (for which I have applied for Letters Patent in Great Britain, No. 26,221,v bearing date November 28, 1902, and in Germany; Hauptbuch, No. 10,279, bearing date August 4, 1903,) of which the following is a specification. 7

This invention relates to a carburetinglamp where the air is automatically and continuously carbureted by being made to pass in a downward direction through a receptacle charged with an absorbent material saturated with light hydrocarbon, such downward motion of the air being effected by the natural increase of density thereof without the use of mechanical means. The present improvement is to provide an apparatus which has a reservoir for containing the absorbent material immediately below the burner, after the style of an ordinary paraffin-oil lamp or'stove, in place of on a higher level, as at present used and considered necessary.

The accompanying drawing showsasectional view of one form of apparatus arranged and provided in accordance with my improvements, and I will proceed to describe the invention with reference to such drawing.

I employ a reservoir a of any suitable Shape, such as the usual circular shape withtapering sides, the said reservoir being of suitable material. I place within the reservoir the absorbentmaterial b, which is preferably in the form of a perforated-block made of the following composition, approximately: two parts, by weight, of plaster-of-paris; one and one-third parts, by weight, of kieselguhr; five and one-half parts, by weight, of water, mixed into a paste and molded into the blocks with the perforations Z running from the top to the bottom of the block and then air-dried. A spacey is left between the top of the block or other absorbent b and the under side of the top of the reservoir wand a similar space 70 between the under side of the block or other absorbent and the bot-tom of the reservoir, the block or other absorbent being held within the reservoir in any convenient manner, such as by resting on projections or clips g a little above the bottom of the reservoir. The block or other absorbent b is then saturated with light hydrocarbon oil, the 'excess of oil being drained off. Air entering an inlet 03 at the top of the reservoir becomes impregnated with the hydrocarbon vapors, and the mixture of resulting gas being heavier than atmospheric air descends through the perforations Z in the block or through passages made in the absorbent and collects in the space is at the bottom of the reservoir. A metal or other tube 0 is fixed in the top of the reservoir into and through a hole made in the block or other absorbent and communicating with the space is at the bottom of the reservoir. A Bunsen, Argand, or other burner m, with glass or other funnel f, is fixed on the top of the reservoir in communication with this tube. A draft is started by heating the air in the funnel, which may be done by applying a lighted match at the bottom of the funnel through a suitable orifice. This draft draws up the gas from the reservoir and enables it to become ignited at the burner. The combustion of the gas itself will after ignition produce the necessary current of air through the air-inlet, the absorbent material, and the central tubes. The gas may be regulated by a stop-cockor similar device, if desirable, which may be applied to a tubular neck-piece 6' between the burner and the top of the reservoir. To insure proper combustion, air may be admitted to the burner through an opening 1), controlled by a movable sleeve 1", as is well understood. The amount of air entering the reservoir to mix with the hydrocarbon vapor may be regulated by any convenient valve (screwed, as in the example shown at n, or

otherwise) at the air-inlet on the top of the reservoir.

The lamp or apparatus may be used for illuminatingor heating purposes.

An incandescent mantle 0 maybe applied to the Bunsen burner for illuminating purposes.

Having nowparticularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is A carbureting-lamp comprising an air and vapor mixing receptacle (4, having an inlet for air at its upper end, and situated below a burner m; said burner m; a valve n, governing said air-inlet to the receptacle; a funnel f, surrounding said burner, and having inlet for air at its lower end; a solidified absorbent IO block 6, contained within said receptacle, such block being in one piece, and having perforations Z, extending directly from the upper to the lower surface thereof; chambers j, and K, respectively above and below said block; and a central tube a, open to chamber 1', and in communication with said burner m, for the purpose and in manner substantially as herein set forth.

JOSEPH MATON.
