IMPROVEMENTS IN JACQUARDS EMPLOYED IN LOOMS FOR WEAVING, AND IN THE MEANS OF OPERATING THE SAME
Year: 1877

page_text: LETTERS PATENT to Orlando Ball and Paul Dracup, of Bradford, in the County
of York, Jacquard Machine Makers, for the Invention of "IMPROVEMENTS IN
JACQUARDS EMPLOYED IN LOOMS FOR WEAVING, AND IN THE MEANS OF
OPERATING THE SAME."
Sealed the 3rd May 1878, and dated the 3rd November 1877.
PROVISIONAL SPECIFICATION left by the said Orlando Ball and Paul
Dracup at the Office of the Commissioners of Patents on the 3rd November
1877.
ORLANDO BALL and PAUL DRACUP, of Bradford, in the County of York, Jacquard
Machine Makers. "IMPROVEMENTS IN JACQUARDS EMPLOYED IN LOOMS FOR WEAVING,
AND IN THE MEANS OF OPERATING THE SAME."
The first part of this Invention relates to the wires and needles of jacquards, and
the improvements consist in forming the eye or hole in the horizontal wire with
two or more loops or twists, so as to give more bearing surface to the vertical wire
which passes through, such hole being formed rectangular or same shape as the
section of the said vertical wire; and in order to pass the hook formed at the top of
such vertical wire through the eye or hole of the horizontal wire, we cut away or
reduce the width of the flat or rectangular vertical wire near the hook, so that it
can pass through the said eye; or, instead of reducing the vertical wire at the top,
where most strength is required, we have the wire of uniform strength (rectangular
in section), and twist the wire one half turn, so that the flat part of the wire, where
the hook is formed, is opposite the thin edge thereof; by this means we obtain more
bearing surface, and the hook is more durable than is the case when the hook is
made flat way of the wire.
The second part of this; Invention relates to the means of operating the jacquard
apparatus, which has previously been done by a rod connected to a crank from the
crank shaft of the loom, such method of driving causing an irregular lift of the

page_text: jacquard. Our Invention consists in operating the lifting rod of the jacquard by
passing the rod through a socket in connection with a swivel stud, so that a
perfectly perpendicular lift is given to the jacquard, and much wear and tear
prevented.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Orlando Ball and Paul Dracup in the Great Seal Patent Office on the
3rd May 1878.
ORLANDO BALL and PAUL DRACUP, of Bradford, in the County of York, Jacquard

the improvements consist in forming the eye or hole in the horizontal wire with
two or more loops or twists, so as to give more bearing surface to the vertical wire
which passes through, such hole being formed rectangular or same shape as the

such vertical wire through the eye or hole of the horizontal wire, we cut away or
reduce the width of the flat or rectangular vertical wire near the hook, so that it
'can pass through the said eye; or, instead of reducing the vertical wire at the top,
where most strength is required, we have the wire of uniform strength (rectangular
in section), and twist the wire one half turn, so that the flat part of the wire, where
the hook is formed, is opposite the thin edge thereof; by this means we obtain more
bearing surface, and the hook is more durable than is the case when the hook is
made flat way of the wire.
The second part of this Invention relates to the means of operating the jacquard
apparatus, which has previously been done by a rod connected to a crank from the
crank shaft of the loom, such method of driving causing an irregular lift of the
jacquard. Our Invention consists in operating the lifting rod of the jacquard by
passing the rod through a socket in connection with a swivel stud, so that a
perfectly perpendicular lift is given to the jacquard, and much wear and tear
prevented.
In order that this Invention may be more fully understood, we herein give
reference to the accompanying Sheet of Drawings illustrative thereof.
Figs. 1, 2, 3, and 4 represent the first part of our Invention. A are the horizontal
wires, which are formed with two (or more) loops or twists, so as to give increased
bearing surface to the vertical wires B, which vertical wires may be partly cut away
near the hook C, as shewn in Fig. 4, in order to pass the said hook through the
horizontal wire loops; or, instead of cutting away the vertical wire, we may have it
of uniform strength, and twist it one half turn or so, as in Figs. 1, 2, and 3, so that
the flat part of the wire, where the loop is formed, is opposite or at right angles to
the other part.

page_text: The second part of this Invention is shewn in Fig. 5. D is the lifting rod of the
jacquard apparatus, which passes through a fixed or swivel stud and socket E, and
is connected by an adjustable boss Frod G to the crank arm H, so that a per-
pendicular lift is given to the jacquard, and much wear and tear prevented.
In conclusion we would have it understood that we claim,--
Firstly. The employment of the horizontal wires A with two or more loops or
twists therein, as and for the purpose herein shewn and described.
Secondly. The employment of vertical wires B, having a portion cut away near
the hook, as and for the purpose herein shewn and described.
Thirdly. The employment of twisted vertical wires B, as herein shewn and
described.
In witness whereof, the said Orlando Ball and Paul Dracup, have hereunto
set our hands and seals, this Second day of May, in the year of our Lord
One thousand eight hundred and seventy-eight.
