Year: 1858

page_text: LETTERS PATENT to Henry Brown, Brook Hodgson, and John Carter, all
of Halifax, in the County of York, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR INTRODUCING AND WITHDRAWING WIRES WHEN WEAVING."
Sealed the 25th November 1858, and dated the 2nd June 1858.
PROVISIONAL SPECIFICATION left by the said Henry Brown, Brook
Hodgson, and John Carter at the Office of the Commissioners of Patents,
with their Petition, on the 2nd June 1858.
We, HENRY BROWN, BROOK HODGSON, and JOHN CARTER, all of Halifax, in
the County of York, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN MACHINERY FOR INTRODUCING AND WITHDRAWING WIRES WHEN
WEAVING," to be as follows:-
This Invention has for its object improvements in machinery for introducing
and withdrawing wires when weaving. For these purposes each of the wires
is made with an enlarged head or end, on one side of which is a vertical
groove, in order that the instrument which takes hold of the wire to draw it
out of the fabric, and moves it again into a fresh shed in the warp, may for
the time act on such head, and readily leave hold thereof at the proper time.
The instrument and apparatus by which the wires are drawn out of the fabric,
and introduced into fresh sheds in the warp, consist of a sliding vertical bolt,
which moves between V guides, which are carried by a sliding frame, which

page_text: moves in horizontal V guides in a direction to and from the recd. The sliding
bolt is formed with a projection at its lower end, which fits into the groove
formed on one side of the head of each wire, and such bolt is constantly drawn
downwards by a spring. The sliding bolt has at its upper end forked pro-
jections or instruments suitable for raising such sliding bolt when the forked or
projecting parts are acted on by an instrument worked by a cam or otherwise.
In addition to the projection on the lower end of the sliding bolt, which takes
into the groove on the side of the wire head, there is also a projecting spring
plate which comes on the other side of the head of the wire to that on which
the groove is formed. The sliding frame which carries the sliding bolt has the
following movements given to it by cams and levers, or by other convenient
means: A motion at right angles to the selvage of the fabric, in order to
draw out wire from the fabric; then a motion towards a shelf or horizontal pro-
jection on the batten which receives the end of the wire when it is drawn out
from the fabric, the sliding frame going back with the batten; a motion towards
the selvage of the fabric, so as to move the wire into the shed, and then
another motion towards the front of the loom in advance of the batten, in
order that the wire may be beaten up into the fabric before the wire is released
from the end of the sliding bolt. When the beating up has been performed,
and the sliding bolt has been raised, the forward motion is continued till the
sliding bolt comes into position to descend and take hold of the wire next to
be drawn out of the fabric. The head of the wire in the movement forward of
the sliding bolt towards the front of the loom is brought under a spring catch
or hook, which holds it correctly when the sliding bolt leaves it. The pro-
jecting shelf on the batten, which receives the end of each wire when it is
drawn out of the fabric is formed with a notch or recess at that end of it
which is nearest the selvage of the fabric into which the end of the wire passes,
and by a moveable pin or stop is retained for a time.

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 MACHINERY FOR INTRODUCING AND WITHDRAWING WIRES
WHEN WEAVING," upon the condition (amongst others) that we, the said Henry
Brown, Brook Hodgson, and John Carter, our exccutors or administrators,
by an instrument in writing under our or their hands and seals, or under the
hand and seal of one of us or them, should particularly describe and ascertain
the nature of the said Inventi u, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal l'atent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Henry Brown, Brook Hodgson, and
John Carter, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say:-
This Invention has for its object improvements in machinery for introducing
and withdrawing wires when weaving. For these purposes each of the wires
is made with an enlarged head or end, on one side of which is a vertical
groove, in order that the instrument which takes hold of the wire to draw it
out of the fabric, and moves it again into a fresh shed in the warp, may for
the time act on such head and readily leave hold thereof at the proper time.
The instrument and apparatus by which the wires are drawn out of the fabric
and introduced into fresh sheds in the warp consist of a sliding vertical bolt,
which moves between V guides, which are carried by a sliding frame, which
moves in horizontal V guides in a direction to and from the reed. The sliding
bolt is formed with a projection at its lower end, which fits into the groove
5 formed on one side of the head of each wire, and such bolt is constantly drawn
downwards by a spring. The sliding bolt has at its upper end forked projec-
tions or instruments suitable for raising such sliding bolt when the forked or
projecting parts are acted on by an instrument worked by a cam or otherwise.
In addition to the projection on the lower end of the sliding bolt, which takes

page_text: Figure 1 shows part of a plan; Figure 2, part of a transverse section; and
Figure 3, part of a front view of a loom, suitably arranged for introducing and
withdrawing wires according to our Invention when weaving terry or cut pile
fabrics. The other Drawings show several views of some of the parts, full
size, the nature of which being written thereon. it will not be necessary to
repeat the same here. The nature and working of looms of this description
being well understood, it will only be necessary for us to describe the operation
of those parts which relate to our present improvements. a is a slide for
inserting and withdrawing the wires, which is moved to and from the selvage
of the fabric on the fixed guide a¹, a', by the lever arm a², which receives
motion by means of the cam a fixed on the cam shaft or axis. The slide a
carries the horizontal sliding frame or wire holding apparatus b, which moves
to and fro in V-guides or angular grooves in the slide a in a direction to and

page_text: from the reed, or parallel with the selvage of the fabric; c is a vertical sliding
bolt, which moves up and down in v guides or in a groove formed at one end
of the sliding frame b. The sliding bolt c is formed with a projection c¹ at its
lower end, which enters and fits into a vertical groove or recess formed on one
side of the head of each wire, which will be better understood by examining
Figures 4, 5, 6, and 7, of the Drawings, in which the slide 6 and parts for
holding and withdrawing the wires are shown full size. c is a plate or pro-
jection, also formed on the lower end of the sliding bolt e, which comes on the
other side of the head of the wire to that on which the groove or recess is
formed, by which the head of the wire is securely held whilst being drawn
out of the fabric and again inserted in the shed, and the lower edge of the
head of the wire is supported by and rests for the time on the projection or
plate b, fixed on the back of the slide b. is a spring, one end of which is
connected to a pin on the slide b, the other end being connected to a pin fixed
on the sliding bolt c, by which the bolt is constantly drawn downwards. The
upper end of the sliding bolt c is formed with forked projections c, c', by which
the bolt is raised out of the groove in the head of the wire, and this is accom-
plished in the following manner :-When a wire has been inserted in the shed
formed in the warps for receiving it, the forked projections e, e, on the bolt c
come up to and partly embrace the rod or projecting arm d carried by the
vertical sliding bar d', which slides up and down in suitable guides d³, d².
Fixed to the framing d³ is a projection on the lower end of the bar d', which
enters a slot in the end of the lever d, the other end of the lever d' being
acted on by the cam d³ fixed on the cam shaft or axis, by which the bolt c is
raised out of the groove on the head of the wire. When the wire has been
secured by the crossing of the warps and the beat up of the weft, the slide b,
with bolt c, is moved towards the front of the loom into a position over the
head of the next wire to be drawn out, the rod or bar d descends, and the end
of the sliding bolte is allowed to descend and enter the groove or recess
formed in the head of the wire.
The slide b is pushed or moved towards the
front of the loom in the following manner-e is a rod, which moves to and
fro in the guide e fixed to the framing; one end of the rod is caused to act on
the back of the sliding frame b, the other end being connected by a pin joint
to the lever arm fixed on the axis e, and e' is another lever arm fixed on
fixed on the cam shaft or
end of the loom to draw out
the same axis, which is acted upon by the cau
axis. When the slide a is moved to the right-hand
a wire, the projection * on the slide 6 enters between the forked projections
ff, on the under side of the bar, by which the sliding frame b, with the
wire, is moved to and fro, in order to adjust and place the wire holder in a

page_text: position to deposit the wire on the shelf or projecting surface 9 formed on the
batten to receive it. The bar f slides to and fro in the guide f³ fixed to the.
framing, one end being connected by a pin joint to the lever arm f, the other
end of the lever being acted upon by the cam f, all which will be readily
understood on examining the Drawings. The projecting shelf g formed on
the batten which receives the end of each wire when it is drawn out, is formed
with a notch or recess g', at that end which is nearest to the selvage of the
fabric, into which recess the end of the wire passes, and is retained for a time
by the rising and falling pin or stop h, or by any other suitable contrivance,
whilst the batten moves from the front to carry the wire towards the back of
the loom, and to aid in guiding the wire partly into the shed, the pin h being
then withdrawn to release the wire. 9 is an adjustable stop, against which the
end of the wire comes when it is drawn out, and the beat up takes place, and
by which the wire is forced into the notch or recess g'. The pin or rod has
a projection on the lower end, which is acted on by the lever arm h², the
other end of the lever 7 being acted upon by a projecting surface h³ fixed on
the side of the cam d³. i is a spring catch, under which each wire head is
retained correctly in position when the sliding bolt c leaves it to take hold of
and withdraw another wire; j. is an adjustable stop, against which the wire
holder is forced when about to withdraw another wire, in order to determine
the correct position of the bolt cover, and so as to insure its entering into the
groove in the head of the wire next to be withdrawn from the fabric.
In witness whereof, we, the said Henry Brown, Brook Hodgson, and
John Carter, have hereunto set our hands and seals, this Twentieth
day of November, in the year of our Lord One thousand eight hundred
and fifty-eight.
