An Improvement relating to Soldering Appliances.
I, CHARLES EDMUND BACON 17 Molesworth Street Lewisham Kent Journalist
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for its object an improvement in the use of copper bits for
soldering. Instead of a copper bit being placed in a fire as is usually done, an oval
heater, as marked A Fig. 2, in the accompanying drawings, of iron or any other
metallic composition or alloy is heated to redness, then slid on the copper bit B,
Fig. 1. thus keeping the soldering point of the copper bit always clean, & avoiding
the constant cleaning, filing and retinning that accompanies the use of the ordinary
copper soldering tool. The latter is not heated until it is red hot because the
tinning would be melted off the tip of the copper and time wasted and heat escape
while the copper is being filed, cleaned, and retinned. The heater A can be
heated to a white heat (if necessary) and attached to the copper bit B without any
danger of melting the tinning at the tip or soldering point. Therefore the working
capacity measured by duration of heat alone of this improved method is double
that of an ordinary copper bit (of the same weight as the heater A and copper
bit B combined) which is heated by being placed in a fire direct. Two heaters are
used with the copper bit B, so that one can remain in a fire heating while the other
is heating the copper bit.
The copper bit B. Fig. 1 in the accompanying drawings is a cylindrical piece of
copper which is bevelled at one end & has two shoulders C. C. projecting at right
angles an inch from the end which is screwed on an iron shank. The heater A of
which one section is given in the accompanying drawing marked Figure 2, is
heated & is attached to the copper bit B by the latter being thrust through the
groove D in the heater, as marked in Fig. 2. The two shoulders C C as in
Figure 1 travel up the grooves E, E, Figure 2, then turn at an angle of 90° down
the groove G, marked in Fig. 2, in the accompanying drawing, of the section of
the heater A, & drop backward into the recesses F in each half of the heater as
marked in Fig. 2. The heater A is thus attached & locked securely to the copper
bit B Fig. 1, & cannot become detached until the copper bit B is pushed forwards,
the two shoulders C C turned again along the groove G, & withdrawn from the
heater by sliding out of the grooves E E Fig. 2.
The heat travels from the heater A to the chisel shaped point of the copper
bit B & melts the solder which is brought into contact with it there. The copper
bit therefore can be used for soldering without its being placed beforehand into a
fire direct, consequently always remains free & clear of ashes & smoke films, &
ready for use, & no time is lost in cleaning the end of the copper bit & retinning
it which would have to be constantly done if the copper bit B were placed
in a fire.
Having now particularly described and ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what 1
claim is

page_text: (2.) The heater A as Fig. 2, &
(3.) The cylindrical copper soldering bit B with projecting shoulders C, C, as
shown in Fig. 1 in the accompanying drawings.
