PROVISIONAL SPECIFICA
Improved Arrangement of Shearing Machines for Cutting Hot
Blooms or Cogged Ingots.
I, JOSEPH HARTLEY WICKSTEED, of Wellhouse Foundry, Leeds, in the county
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improvement relates to vertical shearing machines as commonly constructed
with a service of live rollers for conveying the bloom from the cogging mill
to the shears and for carrying forward the severed portions of the bloom to a
convenient place of delivery and in which machines the bloom has been
heretofore made to enter the shears over that portion of the casting to which the
lower shear steeling is attached and which may be called the fixed bolster.
My improvement consists in arranging the face of the shears in relation to the feed
and delivery rollers at 180 degrees, or exactly opposite to the present practice and by
this improvement the bloom is fed into the shears on the side where there is no
obstruction from the fixed bolster. The feeding rollers therefore may be brought close
enough to the line of cut to convey into the shears the short remaining piece of the
blooni after the longer portion has been severed from it.
In carrying out this improvement I make the roller frame which feeds the bloom
into the machine, hinged and balanced, so that it will dip as the upper steeling
of the vertical shear descends and recover its level upon its ascent, which
provision has hitherto been applied not to the feeding side of the shears but to the
delivering side.
My improvement facilitates the passage of the bloom through the shears and it
gives the further advantage that the guaging stop which is necessarily on the delivery
side of the machine is disposed under my improved arrangement on the same side as
the fixed bolster and can be more readily made to reach close to the line of cut for
guaging short pieces to be severed.
In machines hitherto constructed for shearing blooms vertically, the bolster forms
an obstruction to the feed rollers and the guage stop is obstructed by the casting at
the back of the upper steeling which is fixed to the vertical slide. By reversing the
face of the shearing machine in relation to the roller service both the guage stop
and the feed rollers are unimpeded up to the faces of the steelings.

1, JOSEPH HARTLEY WICKSTEED of Wellhouse Foundry, Leeds, in the County of
York, Engineer, 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 improvement relates to vertical shearing machines as commonly constructed
with a service of live rollers for conveying the "bloon: from the cogging mill to the
shears and for carrying forward the severed portions of the bloom to a convenient
place of delivery and in which machines the bloom has been heretofore made to enter
the shears over that portion of the casting to which the lower shear steeling is attached
and which may be called the fixed bolster.
My improvement consists in arranging the face of the shears in relation to the feed
and delivery rollers at 180 degrees or exactly opposite to the present practice and by
this improvement the bloom is fed into the shears on the side where there is no
obstruction from the fixed bolster. The feeding rollers therefore may be brought close
enough to the line of cut to convey into the shears the short remaining piece of the
bloom after the longer portion has been severed from it.
In carrying out this improvement I make the roller frame which feeds the bloom
into the machine, hinged and balanced, so that it will dip as the upper steeling of the
vertical shear descends and recover its level upon its ascent, which provision has
hitherto been applied not to the feeding side of the shears but to the delivering
side.
My improvement facilitates the passage of the bloom through the shears and it gives
the further advantage that the guaging stop which is necessarily on the delivery side of
the machine is disposed under my improved arrangement on the same side as the
fixed bolster and can be more readily made to reach close to the line of cut for guaging
short pieces to be severed.
In machines hitherto constructed for shearing blooms vertically, the bolster forms
an obstruction to the feed rollers and the guage stop is obstructed by the casting at the
back of the upper steeling which is fixed to the vertical slide. By reversing the face
of the shearing machine in relation to the roller service both the guage stop and the
feed rollers are unimpeded up to the faces of the steelings.
My invention will be clearly understood by reference to the annexed drawings in
which at figure 1, I show a longitudinal section of the shearing machine and service
of live rollers and at figure 2 a transverse section of the feeding roller frame and an
elevation of the shears. In these figures A is the bloom or cogged ingot which has
been conveyed in the direction of the arrow from the cogging mill. B is the portion
of it that has been measured by the guaging stop and severed by the cut. C is the
guaging stop which as shown has been lifted above the line of its action so as to allow

page_text: the severed portion of the bloom to pass under it for delivery. D is the roller frame
which feeds the bloom through the machine and E is a hydraulic cylinder in constant
connection with an accumulator and which balances the roller frame which is hinged
at K in such a way that it will dip as the upper steeling of the vertical shear descends
and will recover its level upon its ascent. F is the main part of the shearing machine
G is the roller frame for delivering the severed portions of the bloom to a convenient
place for removal.
H is the fixed bolster of the shearing machine and J J are the castings at the back
of the upper steeling.
It will be clearly seen that the bolster H in this my improved arrangement does
not intervene between the cut and the last of the feeding rollers as it has done in
previous vertical bloom shearing machines. Also it will be observed that the guaging
stop can approach close to the face of the upper steeling without impediment which is
not the case in machines conversely arranged as hitherto.
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 :-
A vertical bloom shearing machine served by live rollers in which the bloom is fed
into the machine on the side opposite to the fixed bolster.
