page_text: LETTERS PATENT to Frederick Charles Winby and Clifford Etches Winby,
both of Cardiff, in the County of Glamorgan, Engineers, for the Inven-
tion of "IMPROVEMENTS IN THE APPLICATION OF POWER IN ACTUATING ROLLS
IN ROLLING METALS."
Sealed the 21st August 1866, and dated the 24th February 1866.
PROVISIONAL SPECIFICATION left by the said Frederick Charles
Winby and Clifford Etches Winby at the Office of the Commissioners
of Patents, with their Petition, on the 24th February 1866.
We, FREDERICK CHARLES WINBY and CLIFFORD ETCHES WINBY, both of
Cardiff, in the County of Glamorgan, Engineers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE APPLICATION OF
POWER IN ACTUATING ROLLS IN ROLLING METALS," to be as follows:-
Our improvements in the application of power in actuating rolling mills
consist in applying a ram or piston actuated by hydraulic or steam power to
operate directly a rack bar, which rack bar is placed in connection with a.
toothed wheel or wheels placed on the axis or axes of the rolls, to which
rotary motion will be imparted by the longitudinal motion of the rack.
Instead of the rack being geared with a wheel or pinion on the roll axis, the
wheel or pinion on said axis may gear with a large wheel on an intermediate

page_text: shaft, on which shaft a pinion is also fixed; with which pinion the rack is
geared, thus multiplying the motion and revolution of the rolls. Instead of
employing a rack bar to communicate between the ram or piston rod of the
pressure cylinder and the rolls, a chain may be used wound on a drum fixed
on the roll axis, or it may be on an intermediate shaft, and the motion com-
municated thence by toothed gearing to the rolls..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Charles Winby and Clifford Etches Winby in
the Great Seal Patent Office on the 24th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
CHARLES WINBY and CLIFFORD ETCHES WINBY, both of Cardiff, in the County
of Glamorgan, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Frederick Charles Winby and Clifford Etches Winby, Her special
licence that we, the said Frederick Charles Winby and Clifford Etches
Winby, our executors, administrators, and assigns, or such others' as we,
the said Frederick Charles Winby and Clifford Etches Winby, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE APPLICATION OF POWER
IN ACTUATING ROLLS IN ROLLING METALS," upon the condition (amongst others)
that we, the said Frederick Charles Winby and Clifford Etches; Winby,
our executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same, was to be
performed, and cause the same. to be filed in the Great Seal Patent Office.
within six calendar months next and immédiately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Frederick Charles Winby and
Clifford Etches Winby, do hereby declare the nature of our said; Invention,,
and in what manner the same is to be performed, to be particularly, described.

page_text: and ascertained in and by the following statement, reference being had to the
two Sheets of Drawings bereunto annexed, and to the letters and figures
marked thereon (that is to say) :-
Our improvements in the application of power in actuating rolling mills
consist in applying a ram or piston actuated by hydraulic or steam power to
operate directly a rack bar, which rack bar is placed in connection with. a
toothed wheel or wheels placed on the axis or axes of the rolls, to which
rotary motion will be imparted by the longitudinal motion of the rack.
Instead of the rack being geared with a wheel or pinion on the roll axis the
wheel or pinion on said axis may gear with a large wheel on an intermediate
shaft, on which shaft a pinion is also fixed with which pinion the rack is
geared, thus multiplying the motion and revolutions of the rolls. Instead of
employing a rack bar to communicate between the ram or piston rod of the
pressure cylinder and the rolls a chain may be used wound on a drum fixed
on the roll axis, or it may be on an intermediate shaft, and the motion
communicated thence by toothed gearing to the rolls.
DESCRIPTION OF DRAWINGS.
:
This Invention is illustrated in the accompanying Drawings, Figure 1 of
which shows a side elevation, and Figure 2 a plan of the gearing by means
of which we produce the. rotary motion of the rolls applied to an ordinary
blooming mill..
A, A, are the blooming rolls which may be grooved as desired, mounted in
suitable standards B carried by a bed plate C all as usual. The axis of the
lower roll is provided with a pinion D gearing into a rack bar E, by the
longitudinal motion of which the rolls are rotated; this rack bar E works
back and forth in a suitable frame F, and is connected at one end to the
cross head G of a rod H fixed to the plunger of an hydraulic cylinder I, or it
may be the piston rod of a steam cylinder, the cross.head G sliding in grooves
in the sides of frame F. Motion is communicated to the ram plunger or
piston of the hydraulic or steam cylinder, producing the longitudinal motion
of the rack which drives the pinion on the roll axis, and produces the
desired rotary, motion of the rolls. R. is the masonry or bed on which the
rack frame and cylinder are placed, and L the regulating screw for. adjusting
the position of the rolls nearer or further from each other. a, a, are friction
rollers for facilitating the traverse of the rack. Instead of the power for
working the rack being obtained by the pressure of water on the ram or
plunger of an hydraulic cylinder a steam cylinder may be substituted therefor,
the steam acting on a piston and cross head for producing a similar longitudinal

page_text: reciprocating motion of the rack with the object of rotating the rolls in the
manner before described. In order to render the reciprocating motion of
the rack E self-acting we apply a sliding longitudinal bar 6 connected with
the valve, which operates in connection with two pins c and a pin d projecting
from the rack or piston rod, so as to reverse the rolls at any required range
or extent of traverse.
Instead of the above arrangement we may arrange the gearing in the
manner represented in Figures 3 and 4, which show a side view and plan of
apparatus applied to an ordinary rolling mill for producing the rotary motion
of the rolls. In this arrangement the power is transmitted through an
intermediate wheel or multiplying gear by which the speed and consequently
the number of revolutions of the rolls is increased. In this modified arrange-
ment the hydraulic or steam cylinder, cross head, rack, and pinion are the
same as before described, but instead of gearing the rolls directly with the
rack by means of a pinion D mounted on the axis thereof, the rack gears
with a pinion K fixed on an intermediate shaft M, on which is also fixed
a large toothed wheel N gearing with a pinion O on the axis of the lower
roll. By this means a greater number of revolutions of the rolls are pro-
duced with the same extent of traverse of the hydraulic ram. An hydraulic
or steam cylinder may be applied at both ends of the rack, which may be
advisable for apparatus of large dimensions, one for the backward and the other
for the forward motion. A rack may be placed both above as well as below
the driving pinion if desired, for the purpose of applying power at two points
diametrically opposite, and rendering it equal in both directions. For this
purpose duplicate hydraulic or steam cylinders may be used, or a chain may
be carried from the same piston or ram over a turning pulley, and the power
from one hydraulic ram or steam cylinder caused to operate in both directions
simultaneously.
According to a further modification, instead of employing a rack bar to
communicate between the ram or piston rod of the pressure cylinder and the
rolls, a chain may be used connected to the piston, cross head, or ram, and
wound on a drum on the roll axis by exerting the power of the hydraulic or
steam cylinder on and causing it to wind and unwind in the one direction or
the other, the rolls are caused to rotate as desired; or the drum might be
mounted on an intermediate shaft, and the motion transmitted to the rolls
by toothed gearing communicating therewith. In this arrangement it may
be desirable to employ separate hydraulic rams or steam cylinders for pro-
ducing motion in the different directions.
Having described the nature of our Invention, and the manner of per-

page_text: forming the same, I declare that what we claim as our Invention to be
protected by the herein-before in part recited Letters Patent is, the applica-
tion of power to cylindrical rolls for rolling metals from hydraulic or other
pressure cylinders, in the manner and as herein-before described.
In witness whereof, I, the said Frederick Charles Winby, for myself
and on behalf of the said Clifford Etches Winby, have hereunto set my
hand and seal, this Twenty-second day of August, in the year of our
Lord One thousand eight hundred and sixty-six.
