SELF-HEATING SOLDERING-IIRON.

SPECIFICATION formingpart of Letters Patent No. 658,532, datedA September 25, 1900.

Application filed November 14, 1898. Serial No. 696 ,348. (No model.)

To all whom z'ft may aon/cern.:

Beit known that I, HENRY A. ROSS, of Kansas City, in the countyof Jackson, in the State of Missouri, have invented certain new and useful Improvements in Self Heating Soldering-Irons,of which the followingis a full,clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates To improvements in self-heating soldering-irons in which by connection of the tip or soldering-point with a vapor-burner supplied-with gasolene or other light hydrocarbon oil the soldering-point is kept continually heated and ready for work, thus avoiding the waste of time necessary to changing the iron and giving the tool a facility in use in many places and under many circumstances where it would be highly ineon venient,if notimpossible,to carrya plumbers furnace for heating the irons; and my invention consists in certain features of novelty hereinafter described, and pointed out in the claim.

Figure l represents an elevation of a soldering-iron embodying myimprovements and invention. Fig. 2 represents a View, partly in cross-section, of the cup for holding the gasolene. Fig. 3 represents a view, partly in cross-section, showing the manner of connecting the soldering tip with the vaporburner.

Similar numerals refer to similar parts throughout the several views.

l represents a vapor-burner, in which the oil or gasolene is vaporized in passing through the tubular vaporizer 2 and in which the flow of the oil and-discharge of the vapor are controlled and regulated by the needle-valve l1. Such vaporizer, provided with a needle-valve, being of usual and familiar construction this part of the burner is not shown in detail.

3 represents a tube con nected with the vaporizer and having threaded upon its opposite end a soldering-tip 7. Said soldering-tip has formed within it a pocket 8, forming a combustion -chamber therein, and is provided with the draft-openings 9, communicating with said combustion-chamber. Said tube 3 forms a mixing-chamber 3a and has cut or formed in it an air-gap 6, between the mixing-chamber 3 and the vaporizer, for the admission of air to the mixing-chamber, there to mix with the vapor passing from the vaporizer into the same. It has also cut or formed in it an air-gap l0, between the mixing-chamchamber, being highly heated and raretied,

but not burned, has mixed with it a large amount of air entering at the air-gap 6, producing a gas or carbureted air, which enters said combustion-chamber in the tip at a high temperature and with high heating power. Upon said tube is provided a sleeve' 4, having the openings 5. Said sleeve is arranged to slide over and cover the air-gap 6 between the mixing-chamber and the Vaporizer, and for this reason when the tool is used in exposed places'(her e exposed tothe wind or to strong currents of air) there is danger that the vapor passing from the vaporizeracross the air-gap will be blown aside and out at the air-gap and not pass into the mixingchamber.. The sleeve will prevent this, while still admittingacertainamountofairthrough the openings 5 to mix with the Vapor; but when not used in such exposed places the sleeve should be slipped back and the air-gap left open, as to obtain the most effective action ofthe tool a larger amount of air is required to mix with the vapor than can pass through said openings.

It will be observed that when in operation as the gasolene is vaporized in the vaporizer 2 and the vapor issues therefrom with considerable-force in crossing the air-gap 6 a quantity of air will by suction be drawn in and in the mixing-chamber 3 will become mixed with the rarefied'vaportherein, forming a gas or earbureted air of high heating power. This mixed vapor and air or earbureted air, thence crossing the air-gap 10, will enter the combustion-chamber formed by the pocket 8 in the soldering-tip and is there ignited, the air-gap 10 providing for the admission of such amount of air to the combus- IOO tion-chamber as is necessary to complete combustion therein, it being further observed that by the arrangement of the air-gap 10 adjacent to the combustion-chamber in the tip the combustion is confined to this combustiowchamber, and the heat therefrom is d, prevented by the air-gap 10 from acting back' upon and in the mixing-chamber 3 to the extent of producing combustion `therein,i there being no combustion or flame in the mixing-chamber, and the mixing-chamber 'is` thus fitted and adapted to perform properly and at all times its office as a miXing-chamber. This result is one of the leading 'features and principal advantages of myinvention, for as there is no coinbustionor flame in l the mixi 11g-cham ber the vapor becomes highly rarefied and thoroughly mixed with the air,y coming in at the air-gap 6, `and the mixturel or carbureted air `enters the combustion-i cham ber of the tip in a condition for the most* effective action, and the carburetedair be ing of high heating-power and the combus#V tion taking place in and being confined tothe; v

tip the result is most effective for heating the' Tip with the least consumption and least waste of material. 12 represents a vessel containing gasolene and is provided with an extension 13, forming the handle of the tool.

` 14 represents a tube connecting'the vesselA with the burner through the ordinary gas union l5, upon which the burner and its tip` turn, adapting it for use in the most con venient position. As shown in Fig. 2, said tube extends within the vessel and is provided with the wicking 16. Also within the` vessel is arranged the conical or funnely shaped partition 17, the purpose of which isj lo retain the oil around the tube when the` u tool is used in such position that the vessel stands inverted. This partition may, 110W-, ever, be omitted and the wick extended back into the extension 13, it being found in practice that the Wick will take up enough of the oil to supply the burner.

18 represents an air-bulb having the usual valves and communicating with the stein 13 of theoil vessel `for supplying air-pressure upon the oil in the vessel, and thus supply a desired pressure to insure proper feeding of `the burner, a valve 19 beingiprovided to close the communication and maintain the pressure. The air-b ulb and its connections, being old and Well known, are not shown in` detail. y By this construction and arrangement is provided a solderingiron that is self-conrained and always ready and convenient for use and when in use is kept `constantly and uniformly heated, thus `avoiding the annoy- 'ance met in the ordinary iron as it begins to get cold and also `savingthe trouble and time in changingand heating `the irons.

Having thus fully described my improve- `ments,`what I claim as'myinvention, and desire to secure by Letters Patent, is-

A self-heating soldering-iron consisting of the combination with a vapor-burner, and a soldering-tip secured upon and forming part of the burner, of `an oil vessel, a tube conuiectingsaid vessel with the burner and extending 'within `the vessel, `a cone or funnel shaped partition arranged within said vessel, and an extension on said vessel forminga `handle Wherewith Vto handle the tool, substantially as Set forth.
