Hardwick at the Office of the Commissioners of Patents, with their
Petition, on the 7th April 1868.
We, FREDERICK SIMPSON, of Handsworth, in the County of Stafford,
Machine Fitter, and SAMUEL HARDWICK, of Handsworth, aforesaid,
Metal Roller, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR ROLLING SHEETS OR PLATES OF IRON FOR THE
MANUFACTURE OF TIN AND TERNE PLATES, WHICH IMPROVEMENTS MAY ALSO BE USED
FOR ROLLING SHEETS OF IRON FOR OTHER PURPOSES," to be as follows:―
Sheets or plates of iron cut of the proper size for the manufacture of
tin and terne plates are previous to the pickling process subjected to
a final rolling for the purpose of reducing the thickness of the plates and
for removing the scale from the surface of the said plates. This reducing
and brightning of the plates is called the cold rolling process, and is
commonly effected by two separate pairs of hard or chilled rolls, the
plates being fed to the rolls by hand.

page_text: Our Invention consists in combining two pairs of hard or chilled rolls
into a machine in the manner herein-after described, and passing the
iron sheets or plates through the-said two pairs of rolls at one operation,
instead of passing the sheets or plates through separate pairs of rolls at
two operations as is ordinarily practised.
Our Invention consists further of self-acting mechanism for feeding
the sheets or plates to the said combined rolls.
In constructing machinery for the rolling of sheets or plates of iron
according to our Invention, we arrange two pairs of hard or chilled rolls
of the ordinary kind side by side or parallel to one another, and at a short
distance apart, the said pairs of rolls being geared together by toothed
gearing. Between the two pairs of rolls a flanged guide roll is situated.
This guide roll is geared to and receives motion from the second pair
of rolls by means of a driving band or other gearing. The top of the
guide roll is situated on a level with the top of the lower roll of both pairs
of rolls. In front of the first pair of rolls a horizontal feeeder is placed.
This feeder consists of a shallow box open at its front end, to which a
reciprocating sliding motion is communicated from the shaft of the lower
roll of the first pair of rolls by a crank and connecting rod. By means
of a vertical slide the said box of the feeder may be lengthened or
shortened to suit the length of the plates to be rolled by the machine.
When the feeder has made its retiring motion, and is about to advance
towards the rolls, a plate is placed in the box of the feeder. The edge
of the plate is by the advance of the feeder introduced between the first
pair of rolls, by which it is seized and carried through the said rolls. As
the plate passes from between the first pair of rolls it is deposited on
the guide roll described, by the motion of which guide roll it is. carried
between the second pair of rolls. The plates after passing from the
second pair of rolls are received upon an inclined table, down which they
slide into a truck or other receptacle placed to receive them. By the
operation of the two pairs of rolls the thickness of the plate is reduced,
and the surface of the said plate made bright by the removal of the scale
therefrom. Platforms or projecting ledges carried by the framing of
the combined rolls are situated on either side the guide roll to assist in
conducting the plate from the first pair of rolls and introducing it into
the second pair of rolls.
By the use of our Invention great economy in labour and facility and
speed in conducting the rolling process are secured.

page_text: Although our Invention is especially applicable to the rolling of iron
plates or sheets for the manufacture of tin and terne plates, yet our
said Invention may also be applied to the rolling of iron plates or
sheets for other purposes.
