but different metals can be welded one 70
another in many combinations, extending
the applications of the process to the attain
ment of results heretofore impossible IN
metal working; while the tensile strength
of the YIELDS, as shown by mechanical tests,
under the direction of the United States
Ordnance Department, are all that can be
desired.
THE ELECTRIC WELDING APPARATUS.
"The machines built by the Thomson
Electric Welding Company are generators
OF electricity, so constructed as to produce
in the most economical manner the low
pressure currents essential for welding and
for similar work. They are of sizes and
types suited to the kind and section of the
metal to be worked.
"The dynsmos are built to take power from
any source, and the welding machines con-
nected BY wires to operate wherever it may
be convenient to locate them.
1.-The machines now being manufactured
are so graded as to apply to various kinds OF
work, from the smallest wire to bars of over
three inches in diameter. For heavier
work, such as large forgings of locomotive
frames, car axles, shalting, ETC., special
forms of machines adapted to the purpose
will be supplied by the company, while by
the use of specially adapted holders and
clamps applied to the standard forms of ma
chimes, various shapes and irregular sizes of
metal pieces may be united without diff
fculty.
1.-The welding or working is much more
economical and far superior to that produced
by the ordinary methods, while the currents
used are of such low pressure as to render
any danger of shocks impossible.
PRACTICAL VALUE OF THE WELDING
PROCESS.
''The variety of uses to which this method
applies is almost endless. A brief state
ment, however, of a few of the applications
is here given.
/. Joining of wires of copper, iron or
other metals, or bars of similar or different
shapes and sections.
q Making joints at angles with bars, as T
or Y joints.
g. "Making chains of links with double
YIELDS, if desired, both joints being formed
at one operation; and ranging from heavy
cable to jewelers. chains, of the same or
different metals.
l. Constructing or joining, end to end,
pipe of all kinds and OF large or small diam
eters; working or joining, etc., lead pipe;
Welding connections or elbows into lines
OF pipe, thus forming non-leaking joints,
available Tor natural gas and petroleum
lines: welding into long lengths pipe for re-
frigerating or brewery purposes; welding
safe-ends to boiler tubes, etc.
5. welding rings and hoops for barrels,
casks and tanks; welding carriage or wagon
tires; mending broken tires, hoops or bands;
welding eve rings to the ends of bars; and
making rings of precious metals.
6. Uniting steel with iron in the manu-
facture of agricultural implements, dies.
tools, etc.
z. Repairing tools, lengtheniDg or short
ening rods, bars, screws or bolts.
s. welding cast-iron pieces in construct
ing machinery such as frames, fittings, etc.;
uniting, il desirable, cast or malleable iron
to wrought iron or steel.
9. welding carriage or wagon gears, fifth
wheels, shift rails, shaltirons, dasher frames,
and practically all similar work done at the
present time by the old forge methods.
10. welding carriage and wagon axles of
various sizes and sections, the gauge being
easily maintained by special appliances at
tached to the welding apparatus.
ORGANIZATION.
Although this company was only organized
till 1888 it has now large and well ap-
pointed factory at Lynn, Mass, and is run
ming its force night and day to fill present
orders, being unable to supply the demands
made upon it. In consequence of which
the factory facilities will be doubled within
the next 80 days.
GRATIFYING RESULTS.
Every machine placed upon the market
has given perfect satisfaction. They are
now being placed in the various works for
welding pipe, wire rods, carriage axles, tires
and similar work demonstrating great
economy over old processes.
Machines of this make have lately been
placed in two Pittsburg manufactures, viz,
three-inch pipe machine at ''The National
Tube Works" at McKeesport, and a wire
machine at Oliver & Roberts mill on the
Southside.
GENTLEMEN IN CHARGE.
The welding exhibit is under the special
charge OF the company's experts, Messrs. A.
M. Bullard and G. B. Poole.
THE THoMsoN-HoUsToN INTERNATIONAL
ELECTRIC COMPANY,
Under whose special auspices this exhibit
is made, is now making arrangements for
the early introduction of welding appar-
atus into various foreign countries Nego-
tiations are pending for the supply of weld
ing apparatus for use in connection with
mining operations in Mexico and the mining
countries of South America.
THE EUROPEAN ELECTRIC WELDING
COMPANY
Have just closed contracts for the sale of
the Thomson patents to Great Britain for
s., 200 900, and similar contracts will be
closed with France, Belgium and Ger
many.
NOTICE TO METAL MANUFACTURERS.
As it may be interesting to the various
metal manufacturers of Pittsburg to see in
detail the operations OF the different weld
ing machines, special exhibit will be
made by the company in Mechanical Hall,
both in the forenoon and afternoon of Satur.
day, 9th instant.
