IMPROVEMENTS IN CAPS FOR SPINNING FIBROUS SUBSTANCES, AND IN THE MEANS OR METHOD OF MANUFACTURING THE SAME
Year: 1859

page_text: LETTERS PATENT to James Cowgill and John Stocks, both of Bradford,
in the County of York, Mechanics, for the Invention of "IMPROVEMENTS
IN CAPS FOR SPINNING FIBROUS SUBSTANCES, AND IN THE MEANS OR METHOD
OF MANUFACTURING THE SAME."
Sealed the 22nd November 1859, and dated the 31st August 1859.
PROVISIONAL SPECIFICATION left by the said James Cowgill and John
Stocks at the Office of the Commissioners of Patents, with their Petition,
on the 31st August 1859.
We, JAMES COWGILL, and JOHN STOCKS, both of Bradford, in the County of
York, Mechanics, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CAPS' FOR SPINNING FIBROUS SUBSTANCES, AND IN THE MEANS
OR METHOD OF MANUFACTURING THE SAME," to be as follows:-
Our Invention consists in constructing or manufacturing the " caps," employed
in spinning fibrous substances, of wrought or malleable iron instead of cast
iron, as heretofore employed for such purposes. Each cap is formed or con-
structed by welding a solid plug of wrought iron into one end of a suitable
length of tube-welded wrought-iron pipe, which is then bored and turned to
the proper shape or form, and afterwards case-hardened and polished. Caps
thus made are not liable to break or snip in the using, as is the case when
made of cast metal, and yet the cost of production is not greatly encreased.

TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JAMES
COWGILL and JOHN STOCKS, both of Bradford, in the County of York, Mechanics,
send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said James Cowgill and John Stocks, Her special licence that we, the said
James Cowgill and John Stocks, our exccutors, administrators, and assigns,
or such others as we, the said James Cowgill and John Stocks, 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 CAPS' FOR SPINNING FIBROUS SUBSTANCES,
AND IN THE MEANS OR METHOD OF MANUFACTURING THE SAME," upon the condition,
amongst others, that we, the said James Cowgill and John Stocks, our execu-
tors 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 per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calender months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said James Cowgill and John Stocks,
do hereby declare the nature of our said 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 Invention consists in constructing or manufacturing the caps employed
in spinning fibrous substances of wrought or malleable iron instead of cast
iron, as heretofore employed for such purposes. Each cap is formed or con-
structed by welding a solid plug of wrought iron into one end of a suitable
length of tube-welded wrought-iron pipe, which is then bored and turned to
the proper shape or form required, and afterwards case-hardened and polished
by any of the usual methods. Caps thus made are not liable to break or snip in

page_text: the using, as is the case when made of cast metal, and yet the cost of pro-
duction is not greatly increased thereby.
Having thus described tlie nature of our Invention and the best means or
method which we are acquainted with of performing the same or carrying
the Invention into practice, we would observe that we claim as our Invention,
and which we believe to be new within the realm, the manufacture of caps for
spinning fibrous substances, of wrought or malleable iron, in manner substan-
tially as herein described.
In witness whereof, we have hereunto set our hands and seals, this
Twenty-eighth day of February, in the year of our Lord One thousand
eight hundred and sixty.
Signed, sealed, and delivered by the within-
named James Cowgill and John Stocks,
in the presence of
