We, JOHN CALVIN BARBER, Boiler Maker, of 87, Howard Street, Phillipsburg, in
the County of Warren and State of New Jersey, United States of America, and
ZIMRI BARBER, Tower Switchman, of 985, Jackson Avenue, New York City, in the
County and State of New York, United States of America, do hereby declare the
nature of this invention to be as follows:-
This invention relates to soldering bits and it has for its object to provide a
soldering bit with a simple means for heating it and keeping it heated while in
use thus resulting in a considerable saving of time as compared with bits that
require heating in a furnace.
The invention comprises a tank for containing gasoline or other liquid from
which a gas may be generated by mixture with air. Mounted on this tank is a
pump having a valve-controlled communication with the interior of the tank and
also serving as a handle for the instrument. Along the lower part of the tank
extends a pipe which is inclined downward so that its open inner end will lie upon
the bottom of the tank in order that it may receive the whole of the liquid in the
tank. The pipe has an outward extension leading into a mixing chamber which
communicates with a burner, the communication being controlled by a needle
point valve having a stem extending through the end of the mixing chamber and
provided at its outer end with a hand wheel.
The burner consists of a tube having a series of perforations for the admission
of air and provided at its forward end with a soldering bit which has a series of
longitudinal channels to allow of the escape of the burning gas. Arranged below
the burner is what may be termed a preliminary heating pan extending upward
from which is a post having a yoke at its upper end open at one side for facilitating
its attachment by means of a set screw to the mixing chamber. Connected to the
device is a receptacle for solder which is preferably formed in pellets similar to
shot. The bottom of this receptacle is inclined forward and downward and leading
from the lower end of the receptacle is an inclined raceway leading into a

between the receptacle and the raceway may be controlled by a gate valve movable
vertically within the receptacle and held normally in an open position by means of
a spring upon the shank of the gate valve bearing at one end upon the top of the
receptacle and at the other end against a plate on a lever fulcrumed to the
receptacle which lever extends sufficiently far rearward to be in reach of a person's
finger so that by moving said lever upward the gate valve will close the outlet and
prevent the discharge of the solder pellets.
In operation, a sufficient amount of gasoline or similar liquid from which the
gas is to be generated is placed in the container and air is then pumped into the
same and after a sufficient amount of air pressure has been obtained the globe
valve between the pump and tank is closed. The preliminary heating pan is now
filled with gasoline and the same ignited so as to heat up the burner and after the
burner is thoroughly heated the needle valve is opened to allow the gasoline to

the longitudinal grooves in the bit and thoroughly heats the same, the solder
pellets being at same time automatically fed through the opening in the nose of
the bit to the under side, where they will be spread over the same to be soldered in
the usual manner,

We, JOIN CALVIN BARBER, Boiler Maker, of 87, Howard Street, Phillipsburg, in
the County of Warren and State of New Jersey, United States of America, and
ZIMRI BARBER, Tower Switchman, of 985, Jackson Avenue, New York City, in the
County and State of New York, United States of America, 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 relates to soldering appliances and it has for its object to provide a
simple means for heating the bit and keeping it heated while in use, thus resulting
in a considerable saving of time as compared with bits that require heating in a
furnace. We will describe a soldering appliance embodying our invention and
then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar characters of reference indicate corresponding parts
in all the views. Figure 1 is a longitudinal section of a soldering appliance
embodying our invention. Figure 2 is a section on the line 2-2 of Figure 1.
Figure 3 is a section on the line 3-3 of Figure 1, and Figure 4 is a section on
the line 44 of Figure 1.
The invention comprises a tank 1 for containing gasoline or other liquid from
which a gas may be generated by mixture with air. Mounted on this tank 1 is
a pump 2 having a valve-controlled communication 3 with the interior of the tank
and also serving as a handle for the instrument. Along the lower part of the
tank 1 extends a pipe 4 which is inclined downward so that its open inner end will
lie upon the bottom of the tank in order that it may receive the whole of the liquid
when the said liquid becomes low in the tank. The pipe 4 has an outward exten-
sion 5 leading into a mixing chamber 6 which communicates with a burner 7,
the communication between the parts and being controlled by a needle point
valve 8 having a stem extending through the end of the mixing chamber 6 and
provided at its outer end with a hand wheel 9. The burner 7 consists of a tube
having a series of perforations 10 through its wall for the admission of air and
provided at its forward end with a soldering bit 11 which has a series of longi-
tudinal channels 12 to allow of the escape of the burning gas. Arranged below
the burner 7 is what may be termed a preliminary heating pan 13, extending
upward from which is a post 14 having a yoke 15 at its upper end open at one side
and designed to embrace the mixing chamber 6 to which it may be secured by a
set screw 16. Connected to the device is a receptacle 17 for solder preferably
formed in pellets similar to shot. The bottom of this receptacle 17 is inclined
forward and downward, and leading from the lower end of the receptacle is an
inclined raceway 18 leading into a diagonally disposed opening 19 through the
soldering bit 11. The communication between the receptacle 17 and the race-
way 18 may be controlled by a gate valve 20 movable vertically within the

page_text: receptacle 17 and held normally in an open position by means of a spring 21 upon
the shank of the gate valve, bearing at one end upon the top of the receptacle and
at the other end against a plate 22 on a lever 23 fulcrumed to the receptacle 17,
which lever 23 extends sufficiently far rearward to be in reach of a person's finger
so that by moving said lever upward, as indicated by dotted lines in Figure 1, the
gate valve will close the outlet and prevent the discharge of the solder pellets.
In operation a sufficient amount of gasoline or similar liquid from which the
gas is to be generated is placed in the container 1 and air is then pumped into the
same by means of the pump 2 and after a sufficient amount of air pressure has
been obtained the globe valve 3 is closed. The pan 13 is now filled or partly filled
with gasoline and the same ignited so as to heat up the burner 7 and after the
burner is thoroughly heated, the needle valve is opened to allow the gasoline to
escape into the burner and mingle with air to form a gas, which escapes through
the grooves 12 and thoroughly heats the bit while burning. The solder pellets
are at same time automatically fed through the opening 19 to the under side of
the bit where they will be spread over the same to be soldered in the usual manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A soldering appliance, comprising a tank for gasoline or the like, means for
forcing air into the same, a burner having communication with the tank, a valve
for controlling said communication, a soldering bit mounted in the burner, a
container for solder, and a raceway leading from said container to the soldering bit,
substantially as specified.
2. A soldering appliance, comprising a tank for gasoline or the like, a pump for
forcing air into the same, a burner having communication with the tank, a valve
for controlling said communication, a soldering bit mounted in the burner, a
container for solder, and an inclined raceway leading from said container to an
opening through the soldering bit, substantially as specified.
3. A soldering appliance, comprising a tank for gasoline or the like, a pipe
running longitudinally through said tank at its bottom, a pump for forcing air
into the tank, a burner communicating with the tank, a valve for controlling said
communication, a soldering bit supported in the forward end of the burner and
having a hole diagonally through it, a container for solder pellets, a raceway
leading from the said container to the opening through the soldering bit, a valve
for controlling the communication between the raceway and container, a spring
for normally holding said valve open, and a fulcrumed lever for closing said valve,
substantially as specified.
