PROVISIONAL SPECIFICATION.
Improvements in Mills for Rolling Grooved and other Rails.
I, GUSTAVE TRASENSTER, General Manager of La Société Anonyme d'Ougrée
at Ougrée, Belgium, do hereby declare the nature of this invention to be as
follows:-
My invention has for object a novel arrangement in rolls for grooved or other
rails for supporting the vertical roll between the horizontal rolls in such a
manner that the small vertical roll increases the depth of the groove in the head of
the rail.
On the accompanying sheet of drawings
Figure 1 is an elevation of an arrangement of rolls provided with my
improvements.
Figure 2 being a vertical section of the same through line A-B, and
Figure 3 a horizontal section through C-D.
In the groove or opening of the horizontal rolls a a immediately at the side of
the groove for the rail d, a bar e is arranged transversely and constitutes the support
of the vertical flanged roll and of its spindle f¹. This bar c is guided and
supported on each longitudinal side of the rolls a by the girders 99 which are
arranged to move vertically when required in the grooves of the roll housings.
A second cross bar i is also guided and supported from both sides of the rolls a
in the girders g and it likewise extends between the rolls a a and bears upon the
back of the part of the roll.
Bolts m unite the bars c and i, and serve to effect the advance of the vertical
flanged roll for producing the groove for the rails.
In adjusting the bolts the vertical roll f is set in the position best adapted for
rolling the groove in the head of the rail.
By this arrangement I obtain the following advantages
The support of the roll receives on one side pressure from the surface of the
rail, and on the other side pressure from the bar i, in such a manner that it only
sustains a slight strain and may therefore be constructed very light.
The bolts m which unite the bars c and i allow the vertical flanged roll to be
readily advanced when rendered necessary by reason of wear and tear or other
causes.
This arrangement is applicable to any number of grooves requisite for giving the
depth desired to the groove in the head of the rail.

COMPLETE SPECIFICATION.
Improvements in Mills for Rolling Grooved and other Rails.
I, GUSTAVE TRASENSTER, General Manager, of La Société Anonyme d'Ougrée
at Ougrée, Belgium, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention has for object a novel arrangement in rolls for grooved or other

page_text: rails, for supporting the vertical roll between the horizontal rolls in such a
manner that the small vertical roll increases the depth of the groove in the head of
the rail.
On the sheet of drawings filed with my Provisional Specification and illustrating
my invention:-
Figure 1 is an elevation of an arrangement of rolls provided with my
improvements,
Figure 2 being a vertical section of the same through line A-B, and
Figure 3, a horizontal section through C-D.
:-
In carrying out my invention I adopt the arrangement described below:-
In the groove or opening 6 of the horizontal rolls a, a, immediately at the side
of the groove for the rail d, a bar c is arranged transversely and constitutes the
support of the vertical flanged roll f and of its spindle ¹. This bar e is guided
and supported on each longitudinal side of the rolls a by suitable girders g g which
are arranged to move vertically when required in grooves h, h formed for that
purpose in the roll-housings.
A second cross-bar i is also guided and supported from both sides of the rolls a
in the girders g, and it likewise extends between the rolls a a, and bears upon the
back part of the roll.
The cross-bars c and i are united by bolts m, by the adjustment of which the
vertical flanged roll f is advanced as required for producing the groove for
the rail.
To set the vertical roll f in the position best adapted for rolling the groove in
the head of the rail, the bolts m are screwed up or unscrewed as required.
By the above described arrangement the following advantages are obtained :-
The support 7 of the roll receives on one side pressure from the surface of the
rail and on the other side pressure from the bar i in such a manner that it is
subjected to only a slight strain and may therefore be constructed very light.
The bolts m which unite the bars c and i enable the vertical flanged roll f to
be readily advanced as may at any time be rendered necessary by reason either of
wear and tear or other causes.
The arrangement above described is applicable to any number of grooves requisite
for giving the depth desired to the groove in the head of the rail.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In mills for rolling grooved and other rails the arrangement of the cross-bar i
for supporting and retaining the vertical roll fin any desired position for producing
a groove in the head of the rail substantially as herein described, and as illustrated
upon the drawings accompanying my Provisional Specification.
