page_text: HETHERINGTON'S DISCLAIMER AND MEMORANDUM OF
ALTERATION TO MOREWOOD AND ROGERS' SPECI-
FICATION..
In the Matter of a Patent granted to EDMUND MOREWOOD, of Thorn.
bridge, of the County of Derby, Merchant, and GEORGE ROGERS,.
of Stearndale, in the same County, Gentleman, for their Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF IRON INTO SHEETS, PLATES, OR.
OTHER FORMS, IN COATING IRON, AND IN PREPARING IRON FOR COATING
AND OTHER PURPOSES," bearing date at Westminster, the Ninth day:
of October, One thousand eight hundred and forty-five, to which a
Specification was duly inrolled, and which said Letters Patent have
been duly assigned to, and are now vested in MELLOR HETHERINGTON,.
of Upper Thames Street, in the City of London, Merchant.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to Be
entered by the said Mellor Hetherington, as such assignee as aforesaid,
with the Clerk of the Patents of England, pursuant to the Statutes in
that case made and provided.
WHEREAS in the Specification of the said Patent, the Invention was des-
cribed to consist of five parts, and it has since been found that the first, third,
fourth and fifth parts have not turned out to be of such value as to induce me
to retain the same; for which reason I wish to disclaim and I do hereby disclaim
all parts of the Specification which describe and claim the first, third, fourth,
and fifth parts of the said Invention; and as the title of the Invention would
be then more extensive than the Invention which will remain described in the
said Specification, I wish to disclaim and alter so much of the title as will
make the same consistent with the remaining portion of the Invention; and

page_text: ラナ
this I do by disclaiming the following words of the title, " or other forms in
coating iron, and in preparing iron for coating," and I introduce the word " or
between the words "sheets, plates," and I also introduce the words "suitable for
roofing" after the word "plates."
And in order that the effect of the Disclaimer and Alterations may be better
understood, I annex a copy of the Specification as it will appear when the
Disclaimer and Alterations have been made.

"TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDMUND
MOREWOOD, of Thornbridge, of the County of Derby, Merchant, and GEORGE
ROGERS, of Stearndale, in the same County, Gentleman, send greeting.
"WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date
" at Westminster, the Ninth day of October, in the ninth year of Her reign,
did, for Herself, Her heirs, and successors, give and grant unto us, the said
Edmund Morewood and George Rogers, our exors, admors, and assigns,
"Her especial licence, full power, sole privilege, and authority, that we, the
said Edmund Morewood and George Rogers, our exors, admors, and assigns,
" or such others as we, the said Edmund Morewood and George Rogers, our
exors, admors, or assigns, should at any time agree with, and no others,
"from time to time, and at all times during the term of years therein expressed,

"
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, our Invention of "IMPROVE-
"MENTS IN THE MANUFACTURE OF IRON INTO SHEETS OR PLATES SUITABLE FOR
"ROOFING AND OTHER PURPOSES;" in which said Letters Patent is contained a
"proviso, that we, the said Edmund Morewood and George Rogers, shall
cause a particular description of the nature of our said Invention, and in
what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
" and by the same, reference being thereunto had, will more fully and at large
66 appear.
66

"
"NOW KNOW YE, that in compliance with the said proviso, we, the said
"Edmund Morewood and George Rogers, do hereby declare that the nature
"of our said Invention and the manner of performing the same, are fully
described and ascertained in and by the following description thereof,
"reference being had to the Drawings hereunto annexed, and to the figures
"and letters marked thereon, that is to say:"-
66
"Our Invention relates to manufacturing sheets or plates of wrought iron
indented in two or more directions, so as to give strength, and so con-

page_text: "structed that they will go together to cover a surface, making them
particularly useful for roofs of houses."
66
"And in order that our Invention may be fully understood, we will proceed
"to describe the means pursued by us."
66
"Figure 6 represents a side view; Figure 7, a plan; and Figure 8, a cross
"section of apparatus, such aswe prefer to use in carrying out the Invention ;
the other views shew parts separately; j is the bed plate of the machine,
"which has grooves k formed in one direction, and others (7) not so deep in
"the opposite direction. These grooves or indentations receive projections
"k, l, formed on or affixed to the plate m; the plate m is supported on the
"end of the screw n, which passes through a female screw in the frame o,
"and has on its upper end arms and weights similar to an ordinary fly press.
"A piece of sheet metal is placed on the bed plate j, the plate m is then
"caused to descend with considerable force, obtained by the momentum of
"the weighted arms n', by which the plate of metal will have the form
given to it shewn at Figure 9, and any number of such forms may be
combined together, as shewn by the sectional longitudinal view, Figure 10,
and by the sectional end view, Figure 11. In place of stamping sheets of
iron into the required form, the same might be done by means of suitably
formed rollers. We do not confine ourselves to this mode of making the
plates, nor to the precise figure of the indentations, the object of our
"Invention being to make plates of wrought iron, having indentations in
two or more directions, and capable of fitting or going together for covering
"surfaces as herein described."

"Having thus described the nature of our Invention and the manner of
performing the same, we would have it understood that what we claim is,
"the stamping or rolling of sheets or plates of wrought iron, indented in
"two or more directions, so as to give strength lengthways as well as cross-
ways, and at the same time to fit and go together for covering surfaces,
particularly useful for roofing of houses, as herein described."

"In witness whereof, we, the said Edmund Morewood and George
"
Rogers, have hereunto set our hands and seals, this Ninth day
"of April, in the year of our Lord One thousand eight hundred and
forty-six."

In witness whereof, I, the said Mellor Hetherington, have hereunto
set my hand and seal, this Sixth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight.
MELLOR HETHERINGTON. (L.S.)
