Last week a special train came up from
New York TO witness trial OF this ma
chine
The trial Of the machine Was COM
plete success. l, is simple in construc
ton, but OF course heavy. 1t is driven by
two twelve inch belts. over drivers siz
feet 10 diameter, about 100 horse power
used. Two steel wheels were dressed-ths
first 10 twenty minutes, the second 10 six
teen minutes. Three eighths Of an inch
was taken from the diameter. The sur
face Of the wheel is left smooth and chilled
so that file will not cut it. The machine
was speeded at only 5000 revolutions pei
minute. The engineers are pleased with
il. and say it is success. Every wheel
is dressed to exactly the same diameter
Mr. Miliimore proposes to build the ma
chimes and sell them to railroads, charg-
ing royalty. Two wheels can be dressed
at once. The surface OF the dresser OF
the wheel never gets red, The time Of
dressing is chiefly matter OF power
Milimore thinks 300.horse power should
be used for his machine, as perfected
The engineers say all large railroads have
power enough at their works to run tht
machine. The cost will not be greater
than for lathes now used to true wheels
Railroads will not need to carry 80 large
a stock Of extra wheels and labor will bt
saved. The engineers say the New forl
Central has more than 100000 in extr'
wheels from New York 10 Buffalo. Thi'
waste Of capital will be unnecessary sRe
the life OF the wheel is prolonged by thu
process. The engineers estimate that th'
cost by this process to large raiiroad
will be Hfteen cents per wheel, while b!
the processes now III use the cost 10 no
less than SO per wheel. Neither TIL
dresser nor the surface dressed gets so ho
that you cannot hold your haod on II IN
few seconds. All sorts Of manufacturer
apply TO use this process for dressing fs
surfaces, watch machinery. etc.
