To all whom 'it 'may concern.'

Be 1t lgnown that I, EDWARD .Louis SEA- MAN, a'citizen of the United St-ates, and a resident of] the city of Massi11on, Alin the county of Stark and State of Ohio, have.l

invented anew' and Improved Soldering- Tool, of whlch the following is a full, clear, and exact descr1ption of the invention, such as will enable others skilled in the art'to which 1t appertains to make and use the same.

My invention relates to devices whereby the soldering of various articles of manufacture in large .numbers may be conveniently, rapldly and cheaply effected, and it is the object of the improvement Ito secure a steadyand continuous flame within the combustion chamber of the soldering tool furnishing a maximum of heat'with a minimum of gas.-

Another object of vmy invention is to vent the back action of the flame.

A further object is the construction Whereby the ltool may be rotated axially vupon the supply pipe, but not moved longitudinally pre- ' thereof.

A still further object lis the insulation of the soldering bolt, and the combustion chamber.

In order that my invention ma be more fully understood, I have appende hereunto a sheet of drawing showing my invention practically carried out, in which- Figure 1, is a central longitudinal section of the combustion chamber. "Fig..2,

is a cent-ral longitudinal sect-ion of the handle. Fig. 3, is a side elevation. Fig. 4,- is a cross section through the dotted line fw'. fw. Fig. 5, is Aa 'cross section `through the dotted line y. y. Fig. 6, isa cross section through the dotted line e. Fig. 7, is a cross sect-ion through the dotted linem. and Fig. 8 is a central longitudinalsection through an alternative form of soldering bolt.

' Similar characters of reference indicate corvresponding parts in the several figures.

The letter a. lnthe drawings represents the outer tubular casing of the combustion-y chamber having 'air inlets at Z. and an` internal lining b. of heat insulating material such as asbestos or the like, the rear end being flanged inwardly and permanently attached tothe connecting yokej'.` as shown atlO. lemovably' securedto the interiorof the combustion chamber a. between the flange 10. and the sheet metal ring g. is a gauze- "screenh. covering the rear of the'veombustion-chamberiwhich is more plainly shown in F ig.' 7. Secured by means of the screw n.. at the forward end of the casing a. is an -annular sleeve of heat insulating material o.

more fully shown in Fig. 6. said sleeve having a central longitudinal perforation through which passes the soldering boltd. extending Within the combustion chamber and secured vby means of the screw' m. pass' ing through but not in contact with thevv casing a( Attached to the bolt d. and adja-v cent to the air inlets. Z. is an annular flanged y sleeve serving to retain the flame within 'the combustion chamber.

end of the bolt di is detachablyv screwed the soldering tip e., or the tip c., and the bolt 1. 'p

To the forward maybe forged in one piece as shown at d: in Fig. 8 tubular stem l'. having diamctrically opposite perforations at 1.'. is permanently attached at. the forward end to the yoke j'. at Athe rear end is exteriorly screwed the cap t. having a central longitudinal pen l foration through which passes the inneumparts serving as a Bunsen' burner.

s. represents a wooden handle having Va central longitudinal perforation through which passes the 'stem' e. secured thereon by means, ofthe set screw r. screwed into the ferrule '7). which is secured to .the handle s. by means.- of the wood screw Q. A section of the handle being shown in- Fig.A 5'.

In operation it 1s only necessary to connect. the tube j. by means of the iiexible' hose u. to a gas fixture' and turn on the gas which enters the tube j. and escapes at the orifice f e passing down the stem e.l where it. ymixes- `with the necessary amount of air. Passing across the gap f.' 'impingingupon and passing through Ithe gauze-screen lz. into the combustion chamber. The tool isthen held downward and lighted at the'annular opening between the lining b. and the Harige at v the air inlets atfZ where it burns. Wlth a sudden forward motion of the tool, the liame retreats to within the combustion chamber,

. The above described soldering tool willbe round light, simple" and handy." high'degree ofheat-canl be given :to the bolt in a veryrshort time, andthe b'olt will not cool. While in use; and-the combustion is regu'- .lated so 4that a very purpose is prt'xluee'd.l

have shown certain construction for .purpose of illustration, butA it is of course evident. that the' construction may bevar'ied efficient device 'for the without' departing from the spirit of my f invention, I therefore do not wish 4to be Vlimited to .the construction shown. ,l

Having 4thusl described my. invention, If laim and desire to secure by yLetters Pat.
