I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer, 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:-
The object of this invention is to design a machine in which soldering may be done
with great rapidity by unskilled labor; and it consists essentially of one or more
basins designed to hold the solder which is kept in a liquid condition by heat applied
to the basin one or more soldering irons being provided for each basin the said
soldering irons being preferably pivoted so that their pressure against the article being
soldered may be easily regulated by a weight or spring; the soldering end of the iron
being partially immersed in the liquid solder so as to derive a constant supply there-
from to apply on to the surface of the article pressed against and moving past the
point of the solilering iron; the whole being constructed and operated substantially as
hereinafter more particularly explained.
Figure 1 is a perspective view of a machine designed in accordance with this inven-
tion to solder cylindrical work.
Figure 2 is a cross section through the soldering basin.
A represents two parallel rods supported by suitable end brackets B. These rods
are rigidly held in position and form the main frame of the machine.
C is a cross head sleeved on the rods A so that it can be adjusted longitudinally
thereon and held in any desired position by the set screws a. A vertical passage way in
the centre of the cross head C is designed to receive the shank D on the upper end of
which the bearing boxes for the spindle E are formed. The shank D may be adjusted
vertically in its cross head C and held in any desired position by the set screws b.
This provision for adjustment is intended for the purpose of enabling the machine
to be used for the purpose of soldering cylinders of various diameters and lengths;
the cross head C being horizontally adjusted to suit the length of the cylinder and
the shank D vertically adjusted to suit any change in the diameter.
A cross head is secured to the rods A in the same inanner as the cross head C
and may be likewise horizontally adjusted. A bracket G is fastened to the cross head
F and is provided with a sliding plate H on which the face plate I for carrying one
end of the cylinder is journalled. This sliding plate H may be raised or lowered by
the screw so that the face plate I may be altered to suit any change in the vertical
position of the spindle E.
K are basins secured to the rods A in the same mauner as the cross heads C and F
so that they may be adjusted horizontally. Immediately below each basin K I place
a gas jet 1, so so to supply the heat necessary to keep, the solder within the basin K in
a liquid condition.

page_text: On the end of the spindle E I attach a spring spider M designed to fit within and
against the end of the cylinder being soldered. The face plate I is made to fit the
other end and as the spring N is designed to act on the spindle E so as to press the
spring spider M against the end of the object it is fitting against the said cylindrical
object may be readily revolved by imparting the necessary motion to the spindle E
which may be done through the wheel O fastened to the spindle E and capable of
being driven either by hand or mechanical power.
A bell crank P is pivoted at d below the spindle E to which it is connected by
means of a pin or pins e projecting inwardly from the forked end of the crank P and
fitting into an annular groove made in the collar Qattached to the spindle E as
indicated. This bell crank P is provided for the purpose of throwing back the spindle
E so as to permit the removal or the insertion of the cylinder which has been or is to
be soldered.
The simplest way of operating the bell crank P is to attach a foot lever to the end
of the rod R. The soldering irons S are pivoted on the brackets T and their points
are suspended over the solder contained in the basins K. The weights U are placed
for the purpose of imparting an upward movement to the soldering ends of the irons S.
Having now described the general construction of this soldering machine I may
state in explanation of its operation than the can or other cylindrical article to be
soldered is placed on the face plate I and its other end supported by the spring
spider M; the machine being adjusted in the manner hereinbefore described so that
the seams to be soldered shall press against the points of the soldering irons S which
being partially immersed in the liquid solder supply the requisite solder to the seam
as the can is revolved by means of the wheel O; the weights U holding the soldering
irons S against the seams with sufficient pressure to accomplish the desired end.
Owing to the rapidity with which the cans or other cylindrical articles being
soldered can be removed from the machine and the fact that the soldering irons S are
furnished with a constant supply of solder a very large number of cans can be soldered
by this machine and as it is so simple in construction a boy or unskilled labourer is
able to operate it.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
1. A basin containing solder and heated to keep the solder in a liquid condition in
combination with a soldering iron partially immersed in the solder substantially as
and for the purpose specified.
2. A basin heated so as to keep the solder it contains in a liquid condition in
combination with a pivoted soldering iron partially immersed in the solder and
weighted so as to hold the soldering iron against the article being soldered substantially
as and for the purpose specified.
3. A pivoted soldering iron S partially immersed in the solder and weighted so as
to hold the soldering iron against the article being soldered in combination with the
face plate I and spider M designed to hold the cylindrical can against the point of the
soldering iron S and caused to revolve by means of the spindle E substantially as and
for the purpose specified.
4. The cross head C adjustably supported upon and connected to the parallel rods A
in combination with the shank D connected to the cross head C and supporting the
spindle E substantially as and for the purpose specified.
5. The pivoted bell crank P connected to the spindle E as specified in combination
with the spring N arranged substantially as and for the purpose specified.
