CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS POR ROLLING METATS
Year: 1866

page_text: LETTERS PATENT to Peter Kirk,.. of Workington, in the County of
Cumberland, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS POR ROLLING METATS"
Sealed the 12th March 1867, and dated the 7th November 1866.
PROVISIONAL SPECIFICATION left by the said Peter Kirk at the
Office of the Commissioners of Patents, with his Petition,
November 1866.
on the 7th
I, PETER KIRK, of Workington, in the County of Cumberland, Engineer,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS.
IN MACHINERY OR APPARATUS FOR ROLLING METALS," to be as follows:-
My Invention relates to that description of machinery employed in rolling
metals in which three rollers are used one above another and acting together,
and the improvements consist in raising the middle roller in combination with
fixed stationary (that is, unadjustable) bearings, and in making the bearings
of the top and bottom rollers moveable or adjustable, so that the thickness of
the metal passing between the rollers may be regulated by raising or lowering
the top and bottom rollers to or from the middle roller. In order to facilitate
the movement of these top and bottom rollers the framings in which their
bearings are fixed are connected together by shafting and levers to which
springs are applied so that they balance each other.

page_text: The exact position of the top roller is regulated by a screw as usual, and
another improvement consists in adapting or applying a screw beneath the
bottom roller for the purpose of regulating the same, the two screws being
.connected together (or the nuts thereof) by means of gearing, so that both
rollers may be raised or lowered simultaneously.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Peter Kirk in the Great Seal Patent Office on the 4th May
1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
KIRK, of Workington, in the County of Cumberland, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of November, in the year, of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Peter Kirk, Her special license that I, the said Peter Kirk, my executors,
administrators, and assigns, or such others as I, the said Peter Kirk, my
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 "CERTAIN IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR ROLLING METALS," upon the condition (amongst others) that I,
the said Peter Kirk, my executors or administrators, by an instrument in
writing under my, 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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Peter Kirk, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :-
My Invention relates to that description of machinery employed in rolling
metals in which three rollers are used one above another, and acting together,

page_text: and the improvements consist in rising the metal roller in combination with
fixed or stationary (that is, unadjustable) bearings, and in making the bearings
of the top and bottom rollers moveable or adjustable, so that the thickness of
the metal passing between the rollers may be regulated by raising or lowering
the top and bottom rollers to or from the middle roller. In order to facilitatė
the movement of these top and bottom rollers, the framings in which their
bearings are fixed are connected together by shafting and levers, to which
springs may be applied so that' they balance each other.
The exact position of the top roller is regulated by a screw at each end of
the rollers as usual, and another improvement consists in adapting or applying
two screws beneath the bottom roller for the purpose of regulating the same,
the two screws being connected together (or the nuts thereof) by means of
gearing, so that both rollers may be raised or lowered simultaneously.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot,.similar letters of reference being marked upon
corresponding parts of the apparatus.
Fig. 1 represents an end view of the machinery employed for rolling metals,.
having three rollers one above another; this view shews the adjustable
bearings of the top and bottom rollers, and the mechanism for raising or
lowering the top and bottom roller to or from the middle roller.
In Fig. 1, a, a, is the framing of the rolling machine; b, the top roller
which is mounted in the moveable bearings 6', and which are connected to
the vertical shafts c, c, by means of the bars d, d; e is the. middle roller
mounted in stationary bearings e¹ e', the wedge f being employed to withstand
the upward pressure of the middle roller. The bottom roller g is also
mounted in adjustable bearings which are raised to the height required by
means of the screw h, which is worked by the toothed gearing i, i, which
simultaneously acts upon the screw k by the shaft and gearing 1, 7, these screws
being made right and left handed so as to act in reverse directions.
When it is required to remove the top and bottom rollers 6 and g from the
middle roller e the screw k is caused to leave the bearing of the top roller b, at
which time motion being transmitted through the gearing and shaft / to the
bottom screw h causes such screw to withdraw the bottom roller g from the
mildle roller e, the action of which forces the bearings of the bottom roller
against the levers m, m, so as to give through the springs n, n, a yielding rise
to the vertical bars or rods c, c, which act upon the fingers d, d, projecting
from the bearings of the top roller, thereby raising such ruller from the

page_text: middle roller simultaneously with the withdrawing of the bottom roller from
the same, as herein-before described.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the employment and use of a middle roller revolving in fixed
bearings.
Secondly, the employment and use of a top and bottom roller situated
above and below the middle roller, and revolving in moveable bearings, so that
by raising or lowering and adjusting the upper and lower rollers to or from
the middle roller the thickness of metal to be rolled between them is deter-
mined, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Peter Kirk, have hereunto set my
hand and seal, this Second day of May, in the year of our Lord One
thousand eight hundred and sixty-seven..
