Steel Ingots or Slabs or Masses of Steel or Iron in Connection
We, JOHN SPENCER, of the Phoenix Iron Works, Coatbridge, in the County of
Lanark, North Britain, Ironmaster, and CHARLES ROBERTSON, of the same place,
Iron-works Manager, do hereby declare the nature of this Invention to be as follows,
that is to say :-
Our said Invention relates to cogging or rolling mills for reducing ingots, or
slabs, or masses of steel or iron, to suitable forms for subsequent treatment; and
our object is to improve and simplify the apparatus for turning or otherwise
moving the masses of metal subjected to such mills.
In carrying out our Invention the usual driven feed rollers arranged in a hori-
zontal series are employed for moving the metal mass to and from the mill rolls,
and the mass is turned, and moved transversely by our improved apparatus, when
resting on two or more of the feed rollers, the acting parts projecting up in the
spaces between the feed rollers for that purpose.
The acting parts consist of one, two, or more two-armed levers, each lever being
centered on a pedestal or bracket and being formed with a third arm or with a
toothed sector by means of which it is turned on its centre as required. In one
modification there are two pedestals with their levers, and these pedestals are fixed
on one or two slides connected to or forming part of one main slide arranged to be
movable horizontally and transversely on guides on a bed frame. The main slide
is movable by means of a screw shaft driven by any suitable arrangement of
gearing deriving its action from a steam engine or other prime mover; and it
carries an upper slide or block fitted to move along guides formed on it, and con-
nected by rods to the actuating arms of the two-armed levers. The upper slide or
block is movable by a screw shaft carried by the main slide but driven so as not to
be affected by the movements of the main slide. Thus the screw shaft for moving
the upper slide or block may be driven by either spur or bevil wheels the wheel
on it turning it by means of a groove and key and being held by stationary
brackets, whilst the shaft can move on end independently of it.

page_text: Racks and pinions may be substituted for the screw shafts or either of them ;
and either a screw shaft or a rack may be arranged to act directly on a toothed
sector on each two-armed lever, in which case the upper slide or block may be
dispensed with. Instead of the acting levers being two-armed separate single-
armed levers may be used in some cases.
With this arrangement the two-armed levers can be turned for the purpose of
turning over the mass of metal, and they can with their pedestals, be shifted
transversely for placing the mass of metal opposite any desired part of the mill
rolls.

We, JOHN SPENCER of the Phoenix Iron Works, Coatbridge, in the County of
Lanark, North Britain, Ironmaster, and CHARLES ROBERTSON, of the same place,
Iron-works Manager, 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, that is to say :-
Our said Invention relates to cogging or rolling mills for reducing ingots, or
slabs, or masses of steel or iron, to suitable, forms for subsequent treatment; and
our object is to improve and simplify the apparatus for turning or otherwise
moving the masses of metal subjected to such mills.
In carrying out our Invention the usual driven feed rollers arranged in a hori-
zontal series are employed for moving the metal to and from the mill rolls, and the
mass is turned and moved transversely by our improved apparatus when resting on
two or more of the feed rollers, the acting parts projecting up in the spaces between
the feed rollers for that purpose.
And in order that our said Invention and the manner of performing the same
inay be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing our improved apparatus for turning and
moving masses of metal,
Figure, 1, on the accompanying sheet of drawings, is a plan, and figure, 2, is a
side elevation partly in section of our apparatus. In these drawings the same
reference numerals are used to mark the same or like parts wherever they are
repeated.
In carrying out our Invention the parts for acting on the mass of metal consist
of two (or more) two-armed levers, 3, each lever, 3, being centered on a pedestal
or bracket, 4, and being formed with a third arm, 5. The pedestals, 4, are fixed
on two slides, 6, connected by rods, 7, to one main slide, 8, these slides being
arranged to be movable horizontally and transversely to the mill rolls on guides, 9, 10,
on a bed frame, 11. The main slide, 8, is movable by means of a block, 12, acting
on snugs formed on the bottom of the slide, 8; the block, 12, being actuated by
a screw shaft, 13, which works through a screwed hole in it and is carried in
bearings, 14; a spurwheel, 15, being fixed on its outer end which gears with a
spurwheel, 16, on a first-motion shaft, 17, driven by a steam engine or other prime
mover. The main slide, 8, carries an upper slide or block, 18, fitted to move along
guides formed in the inner sides of the slide, 8, and fitted with a crosshead, 20,
which is connected by rods, 21, to the actuating arms, 5, of the two-armed levers, 3.
The upper slide or block, 18, is movable by a screw shaft, 22, working through a
screwed hole in it and carried by the main slide, 8, being driven by a spurwheel, 23,
on-it and gearing with a spurwheel, 24, on the driving shaft, 17. The spurwheel, 24,
is held by a bracket, 25, on the slide, 8, so as to move along with that slide, being
loose on the shaft, 17, but driven by it by means of a groove and key. A clutch, 26,

page_text: is fitted in connection with the spurwheel, 23, on the screw shaft, 22, to allow of
this shaft being engaged or disengaged as required. A clutch, 27, is also provided
in connection with the spurwheel, 16, through which the lower screw shaft, 13, is
driven.
Racks and pinions may be substituted for the screw shafts or either of them ;
and either a screw shaft or a rack may be arranged to act directly on a toothed
sector on each two-armed lever in which case the upper slide or block may be
dispensed with. Instead of the acting levers being two-armed separate single-
armed levers may be used in some cases.
With this arrangement the two-armed levers can be turned for the purpose of
turning over the mass of metal, and they can, with their pedestals, be shifted
transversely for placing the' mass of metal opposite any desired part of the mill
rolla.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
The arranging or combining together of the parts of apparatus for turning and
otherwise moving steel ingots or slabs or masses of steel or iron in connection
with cogging or rolling mills substantially in the improved manner hereinbefore
described.
