Improvements in Apparatus for Use in Melting Metal, and the
Making of Joints in Piping, and like uses.
A communication from abroad by ARCHIBALD THOMAS STURGESS, of Alcala 52,
Madrid, in the Kingdom of Spain, Engineer.
I, EDWARD PERCY SIMPSON, of the Engine Works, Grosvenor Road, Pimlico, in
the County of London, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in apparatus for use in the melting of
solder, lead or other metal and the making of joints in piping and like uses.
In carrying out the invention a metal cage is employed to hold the fuel employed
to melt the metal in a melting pot or crucible which pot is, preferably, provided
with arms or trunnions which trunnions rest in sockets formed for them in the
upper part of the cage.
Near the bottom of the cage is a pipe or conduit which is connected with the
lower part of the pot so as to allow the molten metal to flow out thereby from said
pot, and the flow through the pipe is controlled by a tap, capable of being operated
by a suitable key. Preferably this pipe is screw-jointed at or about the tap for
convenience of disconnection and removal of the "lead pot" and the part of its
pipe which projects through the cage side.
The cage is carried on a skeleton carriage which may conveniently be made
of section metal, the pot resting on the horizontal legs or flanges.
Cross pieces, journals, axes and wheels connected thereto fit the carriage to run
on rails arranged conveniently to allow the truck or carriage to run astride of the
line of pipes whose joints are to be made with the aid of the improved apparatus.
The joints having been properly prepared the "lead pot" on its truck is run over
the pipe track until the spout of the pipe is truly over the pouring point and the
tap is turned until a sufficiency of metal has been poured, when tap is turned off,
and the truck moved to the next point.
By these means a line of joints can be made with great facility, rapidity and
convenience, whilst from the fact that the molten metal during the time that the
various pourings are being made, bas its covering of dirt, scum and other matter
undisturbed thereby preventing, or minimising evaporization and the lead being
used in the making of the joints being taken from the lower portion of the pot, a
good joint is more likely to be ensured, than by the saucepan and dipping methods
now in use.

I, EDWARD PERCY SIMPSON, of the Engine Works, Grosvenor Road, Pimlico, iu
the County of London, 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 :-
This invention relates to improvements in apparatus for use in the melting of
solder lead or other metal and the making of joints in piping and like uses.

Figs. 2 and 3 shew the apparatus by side view and front view respectively.
Fig. 4 shows a side view of the apparatus on a larger scale.
Figs. 5 and 6 show side view and plan view respectively of the cage to the
same scale as Fig. 4.

conduit a¹ which is connected with the lower part of the pot a so as to allow the
molten metal to flow out thereby from said pot, and the flow through the pipe is
controlled by a tap a² capable of being operated by a suitable key a³. Preferably
this pipe a¹ is screw jointed at or about the tap for convenience of disconnection
and removal of the "lead pot" and the part of its pipe which projects through
the cage side. The cage is carried on a skeleton carriage d which may conveniently
be made of section metal, the pot resting on the horizontal legs or flanges.
Cross pieces, journals, axes and wheels e connected thereto fit the carriage to run
on rails farranged conveniently to allow the truck or carriage to run astride of
the line of pipes g whose joints are to be made with the aid of the improved
apparatus. The joints having been properly prepared the "lead pot" on its truck
is run over the pipe track until the spout of the pipe is truly over the pouring
point and the tap is turned until a sufficiency of metal has been poured, when the
tap is turned off and the truck moved to the next point.
"
By these means a line of joints can be made with great facility, rapidity and
convenience, whilst from the fact that the molten metal during the time that the
various pourings are being made has its covering of dirt, scum and other matter
undisturbed thereby preventing or minimising evaporization and the lead being
used in the making of the joints being taken from the lower portion of the pot, a
good joint is more likely to be ensured than by the saucepan and dipping methods
now in use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is: -
1. In melting apparatus for solder metal for the making of pipe joints a swing
pot having trunnions to swing upon and an outlet and conduit controlled by a tap, a

page_text: cage for fire material and having bearings for the pot trunnions in combination
with a carriage body, axes and wheels and rails for same, all substantially as and
for the purpose set forth.
2. The construction and use of melting apparatus for solder metal for making
pipe joints in combination with a wheel carriage therefor adapted to be run in con-
venient proximity to the joints of a line of pipes, as set forth.
