A dssidsratum has long been meth
cd Of lining lead pipes With tin. We
zee that this has bsen accomplished At
Last by a firm in New York From the
Tribune We take the following account
of the process:
For several years two young men Of
the present firm Of CoIEelIs, Shaw Il
willard struggled to produce lead
pipe which should be perfectly lined
with tin. AT last they succeeded. a
short description OF the process will Be
interesting. Their works are extensive,
bat We Will Be limited TO the Hydraulic
Press. This Is the most powerful ma
chine ofthe kind in our country. In
all, il weighs forty tuns- The support
ing rods are Of wrought iron, eight
inches in diameter, and two feet IN cir-
conference. and the nuts are ten inch
6 broad and eleven inches high. The
cylinder is twenty-five inches thick,
and OF i've feet stroke. The pressure
Is two i1ns 10 the square inch, and
can work four tuns, and in the space
Of from six to eight inches in diameter.
from 800 70 600 tHns. Somstimes this
ENORMOUS pressure splits bed piece of
twenty-five inches Of solid iron clear
across.
A cup six inches across and perhaps
ten inches deep, In the center of a heavy
iron block, receives the melted lead TO
the weight OF 50 or 100 pounds. A man !
drill or rod OF the same length presses 4
down through the center Of the melted |
lead, and when the ram Worksa follow |
er attached slowly sinks, exactly filling |
the cup. In the bottom Of this cup Is q !
die, simply ring, with an edge ON the
inside; through this ring the rod Of the
ram enters, bot It does not i'll all the
spacs-the lead fills the balance Of the
spae-aGd il presses out perfectly
FORMED lead pipe. This Il ingenious,
but II Is an invention y years old. To
make lead pipe eneased with tin Is an
men here, In New York, have done.
4 block OF tin Is cast and turned in a
laIhe. II is about 10 inches long, taper
ed, with hole in the center, and OF an
average diameter Of say, two inches,
though s1eh are EnEde Of various sizes,
according TO the size of pipe 10 be manu-
FEATURED. This tspering shape Is 70 give
uniform thickness to the Tin lining. II |
il we're Of eqnaI diameter, the decreased 1
pressure ofths ram would give an irreS-
7l2E thickness. ToGetermine this point |
umsnik. Nov, this t2pering block of |
Tin, freezing cold, is set in the cup, the |
smallest end down, and melted lead is |
lss in from an adjoining furnace, all |
around fl. Immediately the hot lead |
melts the tin block, but only on the |
and here a perfect alloy Is |
formed. Down comes the heavy ram;
the mandril, or rod, passes through the |
heavy block ofttn, tbs follower slowly
press down, and the new compound |
pipe Is forced through the die below. |
As the ram works with steady pressure
the tin and lead are forced ont together, |
without the least change in the original |
position; The only change being in the
shape. or course, the thickness of the
lining VIII depend on the size of the
cone Of tin. Now, although tin Is much
n ore costly than lead, & Is lighter, as
well as stronger; hence, foot OF this
pipe costa only about the same as foot
OF lead pipe. Here we have a pipe
suitable for carrying water, which is
perfectly harmless and 1t is cheap.
