SELF-HEATING sometime-Tool..

SPECIFICATION forming part of Letters Patent No. 650,163, date-a May 22, 1900. Application ld November 1, 1899.` Serial No. 735.647. (No model.)

To all whom t may concern.-

Be it known that I, EDWIN L. BARBER, al citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain newand useful Improvements in Self-Heating Soldering-Tools, of which'the following isa specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to that type oi' tools in which there is employed a hydrocarbon, such as gasolene, as a fuel, the storage-reservoir being in the handle of the implement, the generator and burner being in its shank, and a solderingpoint being secured in such position that the iiame from the burner is thrown upon it.

One object of the present invention is to provide means for feeding the gasolene from the cooler part of the reservoir even when the supply is well nigh exhausted and to pro vide an improved form of soldering point or slug and improved means for detachablysecuring it to the shank of the handle and directing the flame upon it.

Afurther object of the invention is to adapt the tool for other uses than the heating of a soldering-point, means being provided for disconnecting the outer end of the shank, so that the kb urner may be used as a simple torch for heating any object.

These objects are attained in the construction which is fully hereinafter described and which vis illustrated in the accompanying drawings, in which- Figure 1 is a side elevation ofthe tool, a portion being broken away. Fig. 2 is a central longitudinal section. Fig. 3 is a bottom plan. Fig. 4 is a sectional view on the line 4 4 of Fig.,2, and Fig. 5 is a detail section on the line 5 5 of Fig. 2. I

The drawings represent the preferred proportional parts; but the same scale has not been followed through all of the figures, the details being shown in larger views for the purpose of clearness.

The soldering-point 10 is in the form of a slu g pointed at both ends, one end being somewhat iiattened to adapt it for doing what is known in the trade as bottom work. This slug is secured within a collar 11 by means of set-screws 12, so that it may be readily re- Imoved, and either end may be inserted within lthe` collar. shank of the implement consists of a pair of The lower or outer end of the arms 13 13, to which the collar 11 is rigidly lattached and which are detachably connected .with a pair of upper arms 13 13a, which in turn` are secured in any suitable manner to vthe handle. tubular handpiece 14, preferably of wood or other material having lowr conductivity of heat, and a cylindrical reservoir 15 Within the v,member 14.

. The burner consists of a Bunsen tube 16, to the upper end of which is V.fitted alchambered block 18, which constitutes the generator, a supply-tube 17, leading from the reser- `Voir to the chamber of this generator, and a `small .aperture 19, leading from thechamber jof the generator, so as to direct a jet of gas centrally into the burner-tube.`

The latter member consists of a :reservoir, the stem being provided with a `handpiece 25 at its upper end. The stem 22 enters the generator through a suitable stuing-box 23 and is in screw-threaded engage- .ment therewith, so that the valve isl seated and unseated by simply rotating the stem.

A pan 26 is secured to the shank ofthe implement in such position that gasolene may be discharged into it through the port 19 and a suitable aperture in the side wall of the burner-tube 16 for the purpose of starting the generation of the vaporan expedient common in connection with vapor-burners of all kinds.

The reservoir is enlarged in the present inf stance by placing a ball 27 at the outer end of the handle, the upper end 28 of the cylindrical portion of the reservoir 15 being continued into the chamber of this ball. The supply-tube 17 extends upward through the tube 15 into the ball 27, and its extreme end is turned laterally and backwardly, so as to dip into the annular cup that is formed within the ball 27 by the prolonged end 2S of the cylindrical portion of the reservoir. By

means of this expedient the gasolene,fwhich always occupies the spherical portion of the IOO vided with a central duct which is counter-` 32,"so as'fto rei-nforce the check-valve 35.

bored at each end, thecou-nterboreat'the in-` ner end accommodating and providing a seat for a check-valve 33, which is nseated bymeans of a spring 34 reacting against an aperturedD plug or nipple 35,V screwed intothe counter. bore of the plug 32. The counterbore at theouter end'of the plu-g32 is screw-threaded to;Y

receive a member 36, which serves the doubleppurpose of a'nipple -for the attachment of. an air-pump Vnipple and a valve for closing the reduced portion of theV duct of the plug The member-36 has a duct leadingfr'om its outer end-almost to its inner end and then opening laterally through its side Wall, as shown at" 37, a channel 38 being cut from the inner end of thepassage 37 to the inner end of the member;36,;so thatwhen the latter member is'- turned back to unseat it 'as a valve commu-V nication is openedthrough its passage to thet duct of the plug 32. The outer end of the passage 37 is counterboredV and screW-thread-- edyfor the-attachment of an air-pump nipple` (-Not'shown.) `The plug 32 is provided with thumbfpieces 32a, by which it may be con veniently turned, and the member 36 is prof :vided with a thumb-piece 39 for thesame purpose. l' Y v To the lowerends of the arms 13?* there is attachedja band 40, and to the upper 'ends of the arms 13 there is attached a band 41. The bands 40 and 4l are adapted to engage each oth-ertelescopically, their joint being Yof the rabbet form, Vso-as to-'bring their outer surfaces flush. Thumb-screws 42 are employed for securing the'two bands 40 and 41 together, `sothat they may be readily disconnectedto remove 'the soldering-point when it. is desiredjtouse the implement as a torch. The generator and burner are vsecured to the band 40 `by means -of screws 43. v The collar 1l is sufficiently large to conven iently receive theV slug 10, and intermediate of the screws 12 its inner Wall is recessed, as f showneat 44togprprvide 'ample passages. for

the flame, wliichgjbeing directed upon the up' per point, of' the slug 10, isA deflected ',out# Wardl-yby the'tapering forni at this point into thegpa'ssages44 and envelops the entire bodyportion of the-slug 10\Well down' to -its outer point, so that the heat is applied in such man- :ner that it isjnot necessary to depend simplyupongthe'conductivity of the metal'tocarry'; it to the `outergpoint, which it is-the purpose` toheat. Y 1p While I have shown the implement Without a sleeve or .hood for inclosing the burner other than the arms 13, it is obvious that such a device may be applied to the implement, if desired.

In Vpractice the reservoir is filled nearly full of'gasolene, and thenbythe application of an air-pump the -iiuid is placed under compression. Y Upon opening the needle-valve the `iluid will be discharged into, the burnertube 16, and the implement being held in proper position will find its way into the pan ,26... Being ignited inthis pan, the generator quickly becomes heated and the discharge `'frnit'le'p'ort L19 is in the form of a vapor, Vvwhich, igniting from the flame of the pan, quickly heats vthe soldering-point; .Before the pressure developed within the" reservoir by means of the air-pump has been dissipated the handlehas become" heated suiiiciently so that the highly-volatile gasolene will main- -tain a pressure sufticient to expel 'the vapor dro'carbon vapor in the reservoir renders it immaterial also whether a constant supplyof `fluid is provided'within thetube 17, Sothat vthough the reservoir may have'become nearly emptied'of its contents.-

In ordinary practicesuc'h an implement is never Ylong in'one position, and WithoutA 'any precaution upon the part of the Vuser itwill in the ordinary course of his Work'b'e brought ,quency/ to Vkeep the cup surrounding theend 28 of the tubular portion-of the reservoircow `in practice thatit is advisable todirect nthe supply of fuel from the outer end of thereservoir in a tool of this kind,-for the reason that the tool is frequentlyused Wit-h its point elevated, and all ofthe advantages-gained by such means are "present in the implement herein shown and' described, there being the addeda'dvantage of theretentionof a constant supply of liquid fuel Within the cup in the spherical portionof the reservoir well removed from the liame. The implement'when in use is changed in its position sorapidly that there is always a sufficient quantity of .the liquid gasolene delivered -to the tube 17 and at suliiciently-frequentintervals so that "the iame is maintained without interruption or material variation. I claim as my invention'- 1^ tion, a burner,'a reservoir forming thehan'dle `of the torch, a cup Within the reservoir 'and being'located adjacent to one end thereof and having its mouth directed to'such end sothat las such end of the reservoiris raised the cup will be filled with the liquid fuel, and-atube 'leading from such cup `to the burner.
