IMPROVEMENTS IN THE MANUFACTURE OF CARDS FOR JACQUARD WEAVING
Year: 1862

page_text: LETTERS PATENT to John Stewart, of Glasgow, in the County of Lanark,
North Britain, Plumber, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF CARDS FOR JACQUARD WEAVING."-A communication from
PROVISIONAL SPECIFICATION left by the said John Stewart at the
Office of the Commissioners of Patents, with his Petition, on the
24th March 1862.
I, JOHN STEWART, of: Glasgow, in the County of Lanark, North Britain,
Plumber, do hereby déclare the nature of the said Invention for "IMPROVE-
.MENTS IN THE MANUFACTURE OF CARDS FOR JACQUARD WEAVING," the same being
a communication to me from Louis Joseph Fillion, of Grongis Aisne, France,
to be as follows, that is to say :-
This Invention relates to a system or mode of renewing the cards used in
jacquard weaving mechanism, so as to avoid waste of material. Under one
modification an old card is taken, and the layers of paper which form the
card are stripped asunder, and to each layer or half of one card is glued or
otherwise cemented a new strip or length of card paper. The remaining half
of the card is in like manner glued. or cemented to another strip of card paper,
so that the parts again form two perfect cards, and when joined in this manner

page_text: to the new card paper are again ready for being punched. The cards thus
perpared are subsequently submitted to pressure in any convenient manner so
as to cause the layers of cardboard to adhere firmly together, so forming two
new cards.
Another mode or process consists in stripping the old cards asunder, and
cementing the half of one old card to the half of the other card so as to make
the renewed-cards of the original weight. These cards are afterwards re-
punched in the usual way, and used in lieu of new cards.
Under another modification, which avoids the necessity. of unlacing the
cards, the old or used cards have cemented to their faces two strips of card
paper, each piece extending from the end or guide holes to the central holes,
where the cards are united or laced together. The two pieces of card thus
glued to the surface of the cards then cover the old holes so as to admit of
their being again punched to form a new set of cards. This mode of proceeding
avoids the necessity of separating the series of cards, and thus effects a con-
siderable saving of time as well as of material:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Stewart in the Great Seal Patent Office on the
24th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
STEWART, of Glasgow, in the County of Lanark, North Britain, Plumber, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of, Her
reign, did, for Herself, Her heirs and successors, give and grant, unto.me,
the said John Stewart, Her special license that I,. the. said John Stewart,
my executors, administrators, and assigns, or such. others as I, the said
John Stewart, my executors, administrators, or, 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 MANUFACTURE OF CARDS, FOR JACQUARD WEAVING," (a communication from
Louis Joseph Fillion, of Grongis-Aisne, France,) upon. the condition (amongst
others) that I, the said John Stewart, my executors or administrators, by an

page_text: instrament in writing under my hand and seal, or under the hand and seal of
one of them, 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 John Stewart; do hereby declare the
nature of the 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:-
:
The said Invention relates to a system or mode of renewing the cards used.
in jacquard weaving mechanism, so as to avoid. waste of material. Under.
one modification an old card is taken, and the layers of paper which form the
card are stripped asunder, and to each layer or half of one card is glued or
otherwise cemented a new strip or length of card paper. The remaining half
of the card is in like manner glued or cemented to another strip of card paper,
so that the parts again form two perfect cards, and when joined in this manner to
the new card paper are again ready for being punched: The cards thus pre-
pared are subsequently submitted to pressure in any convenient manner so as
to cause the layers of cardboard to adhere firmly together; so' forming two
new cards.
Another mode or process consists' in stripping the old cards asunder, and
eementing the half of one old card to the half of the other card, so as to make
the renewed cards of the original weight. These cards are afterwards re-
punched in the usual way, and used in lieu of new cards.
Under another modification, which avoids the necessity of unlacing. the
cards, the old or, used cards have cemented to their faces two strips of card
paper, each piece extending from the end or guide holes to the central holes,
where the cards are united or laced together. The two' pieces of card thus
glued to the surface of the cards' then cover the old holes so as to admit of
their being again punched to form a new set of cards. This mode of pro-
ceeding avoids the necessity of separating the series of cards, and thus effects
a considerable saving of time as well as of material.+
And in order that the said Invention of improvements' in the manufacture
of jacquard cards may be properly understood; I shall now proceed to describe
the several modes of procedure under which! the said Invention may be
judiciously carried out in practice, that is to say,
Under one modification or system of arrangement a set or other quantity:
of cards which have been used in weaving, and are no longer required for

page_text: the production of the pattern for which they were prepared, are taken, and the
connecting loops are cut asunder. These cards are composed of two or more:
layers of paper pasted together, and the operator now proceeds to separate:
these layers by stripping them asunder, which may be done by first damping
the card, or a portion of it, and then separating them by means of a knife, or
in any other convenient manner. Each half of the old card is then pasted,
glued, or otherwise cemented to a corresponding piece of new card paper, so
to form what is equivalent to two new cards. The cards thus formed partly
of old and partly of new card paper; are then subjected to pressure in order
to cause the layers of paper to adhere firmly together. This completes the
manufacture, and the cards are then ready to be perforated in the ordinary
way to form a new pattern. In this way the old cards which would other-
wise be wasted are utilized and rendered again fit for use, with a consumption
of only one half of the quantity of new paper, and another most important
advantage attending this particular mode of treating the old cards is, that the
weight of each card is not in anyway increased, so that they may be used with
the same facility as cards formed entirely of new paper..
Another mode of making these cards consists in pasting or otherwise
cementing the half or single layer of one old or used card to the half or single
layer of another used card in such manner that the perforations in one half
cover those in the other half, and the two halves of each card thus form two
perfect cards, which are then ready to be punched in the ordinary way, and
used in place of new cards. These cards are however not so satisfactory as
those made according to the first mode, to which preference is given.
In particular cases it may be desirable to avoid unlacing the endless chain of
cards, at the same time render them fit to be repunched to form a new pattern.
This is done by pasting or glueing two strips of card paper to the face of each
card, these strips of new paper extending from the end or guide holes of the
card to the central holes where the cards are connected together to form the
chain. The two pieces of new card paper thus serve to cover completely the
old cards, and when renewed in this manner they are ready to be repunched,
and thus form a new set of cards. In this way the cards are renewed, and
rendered suitable for another pattern, with an expenditure of only half the
quantity of new card paper, at the same time utilizing what would otherwise
be a comparatively useless material.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion, that what I consider novel and
original, and therefore claim as the Invention secured to me by the herein-

page_text: before in part recited Letters Patent, is, the system or mode of manufacturing
or renewing jacquard cards for weaving, in which used or old cards are
rendered' available for another pattern by the addition of new or old card paper
thereto, according to one or other of the modes herein-before described.
In witness whereof, I, the said John Stewart, have hereunto set my
hand and seal, this Twenty-second day of September, One thousand
eight hundred and sixty-two.
JOHN STEWART. (L.S.)
