SOLDERINGr-IRON.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed November 12, 1912. Serial No. 730,831.

To all whom t may concern:

Be it known that we, JOSEPH SUToRIK, a subject of the King of Hungary, and JOHN RANJAK, a citizen of the United States of America, both residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Soldering-Irons, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a self heating soldering iron and its object is to provide a construction adaptable to use either gas or gasolene vapor and to provide a simple controlling valve adjustment and a construction which is compact and cheap to manufacture.

To these ends the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims reference being had to the accompanying drawing in which- Figure 1 is a longitudinal vertical section through a device embodying the invention; and Fig. 2 a side elevation of the same with the gasolene tank removed and a hose connected to supply gas.

In theJ drawing 1 represents a hollow head having a pointed end forming the soldering point and this head is provided with a plurality of openings 2 in its side for the admission of air to the chamber of the head. The head is also formed with an internally screwthreaded opening in one end to receive a cylindrical member 3 which is bored inward from the end which is screwed into the head to form a mixing chamber 4f. The member 3 isV also formed with an axial bore 5 extending inward from its opposite end and is internally sorewthreaded to receive the screwthreaded end 6 of a tube 7 which tube is formed with or carries in its end a needle point 8 to engage a seat 9 therefor formed in the bottom of the internally screwthreaded bore 5. A small passage 10 connects the mixing chamber' i with the valve seat 9 and forms a jet opening through which the gasolene or other combustible fuel is ejected into the mixing chamber. The member 3 is formed with a screwthreaded nipple 11 on its end to receive a tubular coupling member 12 which is sleeved upon the tube 7 and is formed at its rear end with .23 on its outer end.

a socket 13 to receive a handle or grip 14C formed of wood or other suitable material which is not a ready conductor of heat and which forms a convenient hand hold for operating the iron when the same is hot. The end of the tube 7 which projects through the handle 14 is screwthreaded to receive the coupling member 15 on a suitably formed tank 16 or a fiexible tube or hose 17 may be attached to the end of the tube as shown in Fig. 2.

The gasolene tank 16 is formed with a ll opening 18 and is also provided with a screwthreaded socket 19 adapted to receive the barrel 20 of an air pump which extends into the tank and is provided with the usual piston 21 and piston rod 22 having a handle A suitable valve 24 on the inner end of the pump barrel controls the inlet of air into the tank. An air pressure may thus be pumped up in the tank to force the gasolene out through the tube 7 and past the stem-of the needle point into the chamber from which it will escape when the needle point is adjusted away Afrom its seat, passing through the passage 10 into the mixing chamber 4 where it is mixed with air entering through suitable side openings 25 in said chamber.

The needle point is adjusted toward and from its seat by turning the tube 7 which carries it, and the operator may quickly and easily adjust this tube by'holding the same against turning by means of the tank and then turning the handle 14 which is connected to the member 3 by the sleeve 12. If found desirable a suitable packing 26 may be provided between the sleeve and tube so that one will not turn too readily upon the other and the tube is preferably filled with a .packing 27 of suitable material to absorb the gasolene and carburet the air passing through the tube from the tank 16. This packing 27 is not necessary when the soldering iron is heated'by means of gas supplied through the hose 17.

By this arrangement a very simple and compact device is secured which may be readily used either with a gasolene tank or with a gas supply tube.

Obviously changes may be made in the construction and arrangement of parts without departing from the spirit of our invention and We do not limit ourselves to the particular form or arrangement shown.

Having thus fully described our invention what We claim iszl. In a soldering iron, the combination of a hollowl head having an end forming a soldering point, a chambered member secured to the end of the head and formed With an internally screw threaded bore and a valve seat at the end of the bore, a tubular member engaging the screwthreaded bore, a needle valve carried by the end of the tubular member to engage the valve seat and adapted to be adjusted toward and from the same by the turning of the tubular member, a handle grip member sleeved upon the tubular member and connected to the end of the chambered member, and means for supplying fuel to the tubular member.

2. In a soldering iron, the combination of a chambered head formeel With openings and an end forming a soldering point, a member attached to the head and formed with an axial mixing chamber opening into the head, and openings through the sides of the member to admit air to said chamber, said member being also formed with inter'- nally screwthreaded chamber extending in- Ward from its opposite end and formed With a valve seat at the inner end thereof, a passage connecting the valve seat and the mixing chamber, a tubular member having screwthreaded engagement With the screw threaded chamber, a needle point carried by said member and adapted to be adjusted into and out of engagement With the valve seat by turning the tubular member, a handle grip sleeved upon the tubular member and attached at one end to the chambered member, and means connected to the outer end of the tubular member adjacent to the end of the handle grip to supply fuel to the tubular member.

3. In a soldering iron, the combination of a chamber-ed head formed With lateral openings and provided With an end forming a soldering point, a cylindrical member secured to one end of the head and formed with an axial chamber in axial alinement with the head and opening into the chamber thereof to form a mixing chamber, said tubular member being also formed with an inward from its outer end and formed with a passage at the inner end of the chamber opening into the end of the mixing chamber, a tubular member having screwthreaded engagement with the screwthreaded chamber, a needle point carried by the tubular member and adapted to open and close said passage leading into the mixing chamber by the adjustment of the tubular member in its chamber, a sleeve on the tubular member detachably attached to the end of the cham-k Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents, Washington, D. C.
