Messrs. CALLS & SEAToN Your journal having always
been the advocate Of Domestic Industry and Internal Improve
ments have concluded that you would willingly give publ
city the notice Of highly important improvement destined
produce important results in the manufacture Of iron and
railroads 1t is the invention Of Mr. HoRArIo AaEs of
Pals Village Connecticut, for many years an extensive
iron manuacturer and relates the manufacture Of on
particularly for the rails of railroads and the tires or ocomo
tive wheels.
Mr. Ames in the progress Of his business which mainly
devoted the manufacture Of iron for the axs and tires Of
railroad Wheels observed that the tires often split separate
in lines parallel with the plane of the wheel that is the d.
recon Of the length Of the bar Of which they are formed
He also observed that the rails Of railroads often split length
WISE and that the upper surface and the inner edge under
action Of the wheels and their aanches exoae that is
split oil in amna or scales. As these the principal
sources Of expenditure for the repairs Of railroads. Mr. Ames
directed his mind The of this splitting and exoao
! WIN The view to devise remedy.
As experienced ironmaster he knew that bar-iron
sss OF hbre that lie parallel another, and upnng in
the direction tie length Of the bar that these Gbres and
their Paraesm due the gradual eongaon OF the
tails Of caston when changed into wroughon in the pro-
cess OF hammerng and rolling by which the crystals gra-
dualy elongated and in the direction aud that the
traction OF cohesion between the particles constituting each
hoe greater than b.tween the different bres, well
known that bar-on has uch tenacy in The direction
OF the hoes IMAM them From the consideration OF
these weknown facts he concluded that the splitting and ca
oauon were due to the Of sufficient adhesion between
the various hbres constituting the bar and that the only remedy
would DC 20 change the direction the bes by twisting the
oar ~ The process Of rolling that the bres should be
twisted like the hbes Of hempen rope thus substituting
The tenacy OF the bcs for the force which binds them
ther. Ia thls way, " DO Observed that TO split
nate bar OF IRON woud be necessary cut the fbrc
me par acquires 10 IT'S section the strength enaciy
which, on the old plan possessed in longitudinal direction
ms twisting OF Tue tbres is Effected in the operation OF roll
ing, by making The oug-ml Of Of rollers the FIRST
SCI to turn on the axes opposite directions dfaw the ba
81 iron between hem ~ the usual manner and pass lo
The second SET which, IN addition their rotation their
axes Tor drawing The har together the axis Of the
bar and mus " Tie hhres the bar drawn through and
elongated thus causing the bres spiral belca
direction around the Genital ne axis Of the bar IN thu
way VIII DC seen Nat the bar split in straight lines
without breaking The bs aud that therefore the Only
81 railroad bars and tires thus made will be due 10 atror
alone.
This highly important invention Mr.. Ames has lately pa
tented III his country and in Europe and the
Of II IN England has produced quite sensation among III,
nonmasier, who have Tor long time recognised the exs
tence OF an evil which they could remedy and whiel
they now fnd Is rencdcd by invention simple il il
elective Mr. Ames and his valuable invention have beer
noticed in the Englh papers manner highly gratifying
national pride. X.
