ested in the Company That Con-
trolls the Grey Patents.
The Grey process of manufacturing
structural iron and steel promises to
entirely revoIutionize that branch of
industry. The process is the invention
of Henry Grey of Duluth, Mimi,
whose patents are controlled by com
pany in which prominent Scranton
business men are largely interested.
At the mills OF the Ironton company,
at Duluth, the Grey process has been
thoroughly tested and proved entirely
successful.
Ordinarily structural iron and steel
is rolled in the same manner as steel
rails, which makes it Impossible to roll
Il beam, say twenty-four inches in
width. Rolls cannot be obtained that
will stand the strain, In the Grey
process several sets of rolls are used,
one pair rolling the iron or steel flat
and other rolls turning the hanges and
completing the beam.
This invention will make a better and
lighter beam than can be constructed
| unCer the old method of rolliuG, and
also broadens the field by permitting
the use of beams which it has here.
tofore been impossible to roll.
Foreign capitalists have secuTed the
right to manufacture the Grey process
III Europe and have lalready begun
| the construction of large plant at
Luxembourg. to cost several million
| dollars. Ultimately other plants will
be erected in Germany, France, Austria
| aud Hungary. The structural iron
| industry is an immepse thing in Eu
| rope. They use iron beams in their
houses even. In Germany alone last
year, they turned ont .2OO. 900 tons Of
! iron beams. against 800, 900 tons i'm this
country.
A GREAT OPPORTUNITY
l. A firm licensed to manufacture un-
der these patents, controlling the terri
tory east of the Alleghenies. would Sc
/ cure specially which would make
them independent of all competition in
that line. Any disadvantage in loca
tion would be made up by the in
| creased price received for the pro-
! duct,
| The use of structural steel is in
creasine moro rapidly in this country
,
and the future for any concern work
ing under these patents would be very
promising. Concerning the advantages
Of the Grey process a gentleman who
has made study of the matter made
the following statement to a Tribune
reporter, based on the results obtained
at the Duluth MILL
1t will roll lighter sections than is pos

made and is not possibility in collar anC

9Xi5O fianges down to 16 pounds pc

SS425 flanges down to l3.5 per foot
present lightest weight is pounds.
And so on with smaller sizes on a small
cr mill. Such sections as these presen
advantages Of the utmost value to tn
builder, inaSmuCh as he can with then
obtain beam with from 20 to % per cent
less weight that will carry equal amount
of loads, as beams of present make witt
that amount more material.
PROSPECT OF PROFIT,
1t is evident that in this line lays
prospect of profit for the builder and tn
manufacturer, The 2i-inch beam is a
instance of this. 1t will carry with fror
20 to 25 per cent. less material simila
loads, as present make of beams of tha
much heavier weight. We can roll sec
tions on such mills either 3x3, 4xi, 5x:
GX6, 7X7. SxS 9X9, 10X1O 12xl2
These sections, as compression mem
bers, posts or struts would be far NOR
valuable than any other single role
sections made in the world
Take for instance the SXS and the l0X!
either will with 80 per cent less materia
carry equal loads as any present role
single sections, containing the indicate
amount more material.
Again we can, on a mill Of our typ,
roll all sizes of channels that we ca
beams from 3-inch to 24-inch while q
present 1t is not possible to make large
than l5-inch. We can make these section
proportionately lighter than as at preser
made. We can manufacture beams c
girders up to almost any size used sue
as 5OXl2 with proper sized mills built {
our own type.

sizes of beams and channels that Ca
negie can, and the above in addition, fc
probably not above one-ffth of wins
they spent on their largest beam mi
alone, and which makes but five sizes {
beams, viz, from l2-inch to 24-inch, II
elusive. We believe that the Homestead
works have in their beam department a
investment of fully 60 per cent MOI
money in rolls alone than would be r,
{ quired to put in a plant, similar types
ours, that would cover all sizes smoke
Of above. We can make what architec
and builders want, viz, Girders from
to 50 per cent. lighter that will carry ,
much as beams of present standard SCI
