Improvements in Soldering Irons.
I, CHARLES HOLMBERG, Mechanic, of 655 Henry Street, Brooklyn, in the County
of Kings, and State of New York, one of the United States of America, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement.
My invention relates to certain new and useful improvements in self-heating
soldering irons, the object of the same being to provide a simple and cheaply con-
structed soldering iron which is adapted to be connected with a gas supply for
applying heat to the inside of the tips of said iron.
The invention consists of a soldering iron made up of a central tube or pipe, a
wooden handle secured thereto at its rear end, a flexible coupling between the rear
end of said pipe and a gas supply, laterally-extending burners upon the forward
end of said pipe, a frame surrounding said burners made up of a plurality of
bracing rods secured at their lower ends to said pipe having threaded metallic
bands upon their outer ends which are connected by a supplemental bracing rod,
and hollow soldering tips adapted to screw upon said bands and located when in
place just beyond the outer ends of said burners.
The invention also consists in other details of construction and combinations of
parts which will be hereinafter more fully described and claimed.
In the drawings forming part of this specification,
Figure 1 represents a perspective view of my improved device shown connected
with an ordinary gas burner.
Figure 2 is a longitudinal section through the same.
Figure 3 is a detail perspective view of one of the soldering tips.
Figure 4 is a detail view showing the rear end of the central tube of which the
device is made up, and the connection between said tube and the flexible coupling
leading from the gas supply.
Like reference numerals indicate like parts in the different views.
My improved soldering iron is made up of a central tube or pipe 1 having
laterally extending burners 2 upon its forward end and having one or more open-
It has also secured to it near its rear end a
ings 3 adjacent to its rear end.
Adapted to screw
handle 4 of wood or other suitable non-conducting material.
upon the rear end of the pipe 1 is a cock 5 having a nozzle 6 thereon which is
adapted to fit within the pipe 1 and extend up to a point beyond the opening 3 in
said pipe, thereby constituting a Bunsen burner. To the other end of the cock 5
is connected a flexible coupling pipe 7 which is attached at its other end to an
ordinary gas burner 8 as clearly shown in Figure 1. Secured to the forward end
of the pipe 1 is a frame 9 made up of a plurality of curved rods or bars 10, 10,
having secured to their outer ends in pairs rings or bands 11, 11 having internal
screw threads thereon. The said rings or bands 11 are themselves connected
together by means of a supplemental bracing rod or bar 12. Adapted to screw
upon the bands 11, 11 are soldering tips 13, 13 the same being of any suitable form
and construction and interchangeable so that the device is adapted to be used upon

page_text: different kinds of work. When in place the tips 13 which are formed hollow lie
directly opposite the ends of the burners 2, 2, 50 that the ignited gas from said
burners is injected into the inside of said tips.
As thus constructed it will be seen that I have devised an extremely simple, con-
venient and effective self-heating soldering iron which is adapted to be used in
connection with an ordinary gas burner, or with a generator of hydro-carbon vapor
from gasoline, naphtha or other similar oil. The flexible coupling 7 permits of
free movement of the device, and the connection between the said flexible coupling
and the tube 1 provides for the mixture of gas and ain of vapor and air in the
manner of an ordinary Bunsen burner, the combustion of which will produce a
much hotter flame than that of ordinary gas. Furthermore, by reason of the fact
that the soldering tips 13 are removable, I may employ as many different styles
of tips as may be desired, substituting one for the other according to
character of the work to be performed.
the
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is:-
1. In a self-heating soldering iron, the combination with a central tube or pipe,
and means for connecting the same to a gas or vapor supply, of a plurality of
burners upon the forward end of said pipe, a frame connected to said pipe consist-
ing of a plurality of curved outwardly extending bracing rods or bars, threaded
bands or rings attached to the outer ends of said rods or bars, a supplemental brac-
ing rod connecting said bands or rings, and soldering tips adapted to be screwed
upon said bands, substantially as and for the purpose described.
2. In a self-heating soldering iron, the combination with a central tube or pipe
having one or more openings adjacent to its rear end, a cock connected to the
rear end of said pipe having a nozzle thereon adapted to fit up within said pipe,
and a flexible coupling between said cock and a gas or vapor supply, of a plurality
of burners upon the forward end of said pipe, a frame connected to said pipe con-
sisting of a plurality of curved outwardly extending bracing rods or bars, threaded
bands or rings attached to the outer ends of said rods or bars, a supplemental brac-
ing rod connecting said bands or rings, and soldering tips adapted to be screwed
upon said bands, substantially as and for the purpose described.
