To a 2071,0112, it may concern):

Be it known that I, EDWARD L. VIE'rH, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soldering- Irons, of

which the following is a clear, full, and exact description.

desired.

The object of my invention is to provide a gas-heated soldering-iron which can be conveniently used both for domestiowork and at the bench in machine-shops and which is cheap and sim le in construction and by the substitution 0 any one of several bits can be used for either large or small work. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings, .Figure 1 is a side view of my improved soldering-iron.

gitudinal central section.

Referring to the drawings, A represents a suitably extcriorly shaped tubular handle Fig. 2 is a lonwhich is preferably made of wood or other in- I male stub of this gas-cock and leads to and is' connected with a gas pipe or main in any suitable manner. To the screw-threaded end of pipe 1), extending beyond the ferruled end of the handle,.a tubular holder D is secured. This holder consistsof a section of metal pipe which is preferably about one-half or twothirds the length of pipe I), and near the ham die it is provided with draft-openin s c c, that, as shown in the drawings, are preferably located diametrically opposite each other, although they may be differently disposed, if Between these openings and the adjaoent 'end of the holder the latter has a bushing E screwed into its bore. this bushing is closed with the exception of a very small orifice that forms the bore of a jet d; but the diameter of the bore of the re maining portion of the bushing is greater,

and the holder-D is secured to the handle by the pipe 6 thereof screwing into" said bushing. The soldering-bit H is screwed into the end of the holder farthest from the jet. It con- One end of sists of a point of the usual shape having a sharpened or pyramidal-shapedsoldering end and a cylindrical body, the end of which farthest from the engaging point is threaded and screwed into the-adjacent end of the holder farthest from the gas-jet and has a longitudinal groove or channel h therein extending from its butt-end to mediate its ends, said channel being deepest at the butt-end and gradually decreasing in depth as it extends forward. The screw-threaded rear end of this bit is screwed into a cup-shaped socket G, the opposite end of which is reduced in diameter and is provided with a nipple g, that is screwed into the bore of its reduced portion and is removably secured in the end of the holder D by screwing the nipple into the bore'thereof. The end of the nipple g screwed into the socket G preferably extends a distance into the hollow portion or chamber K to near the soldering-bit H and has its end reduced in diameter to form a reduced exit I for the products of combustion as they flow forward against the rear of said bit. When in use, the gases will be so regulated that a. portion thereof will pass directly out through the channel in the soldering-point, while the remainder will be diverted around the hollow chamber in the socket and then out, as indicated by the arrows, thus preventing any back. pressure in the pipe due to extraor dinary accumulation and compression of gas in said chamber.

In operation when the valve B is opened .to permit the gas to flow into the pipe I) a jet of gas is forced into the holder'D and draws bustion will to a greater or less extent be held in the chamber K between the hit and the shoulder made by reducing said socket in end increased in diameter, a removable bit inserted the enlarged end of said socket the end of said holder and socket and pro- I jecting into the enlarged portion of the latter.

A soldering-iron comprising a tubular iolder having air-inlets therein near one end; a gas-jot consisting of a bushing inserted in said holder between said inlets and the contiguous end thereof; a socket fitting the end of said holder oppositesaid jet having its outer and increased in diameter; a removable bit inserted in the enlarged end of said socket provided with a groove extending longitudinally from its retained end toward its sharpened extremity; and a nipple connecting the end of said holder and socket and projecting into the enlarged portion of the latter.

4. A soldering-iron comprising a tubular holder; means for projecting a jet of gas through the same; a socket fitting the end of said holder opposite said jet having its outer end increased in diameter; a removable hit inserted in the enlarged end of said socket provided with a groove extending longitudinally from its retained end and gradually decreasing in depth as it extends toward its sharpened extremity; and a nipple'connecting the end of said holder and socket and projecting into the enlarged portion of the latter.

5. A soldering-iron comprising a tubular j gitudinally from its retained end toward its sharpened extremity; a nipple connecting the end of said holder and socket and proj ecting into the enlarged portion of the lat ter; a handle, and a tube extending longitudinally through said handle the extended end of which is screw-threaded and tapped into the portion of the gas-jet havingan enlarged bore.
