of York, Machine Maker, and William Moxon, of No. 11, Dudley
Grove, Hulme, in the City of Manchester, Machinist, for the
LETTERS PATENT to George Hodgson, of Bradford, in the County
of York, Machine Maker, and William Moxon, of No. 11, Dudley
Grove, Hulme, in the City of Manchester, Machinist, for the
Invention of "IMPROVEMENTS IN APPARATUS EMPLOYED IN WEAVING CARPETS
AND OTHER PRES FABRICS."
Invention of "IMPROVEMENTS IN APPARATUS EMPLOYED IN WEAVING CARPETS
A D...
Sealed the 7th October 1871, and dated the 9th May 1871.
PROVISIONAL SPECIFICATION left by the said George Hodgson and
William Moxon at the Office of the Commissioners of Patents,
with their Petition, on the 9th May 1871.
We, GEORGE HODGSON, of Bradford, in the County of York, Machine
Maker, and WILLIAM MOXON, of No. 11, Dudley Grove, Hulme, in
the City of Manchester, Machinist, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APPARATUS EMPLOYED IN WEAVING
CARPETS AND OTHER PILE FABRICS," to be as follows:-
The improvements have reference to that class of weaving apparatus
such as for which Letters Patent were granted to William Moxon, John
| Clayton, and Samuel Fearnley, dated March 21st, 1857, No. 791, in

page_text: which the movements of the pile wires for their insertion and withdrawal
are in part controlled by the heads thereof sliding in grooves, and the
object of our improvements is to prevent their overshooting in their
movement in these grooves further than for the time desired by the
action of the moving instrument when the loom is suddenly stopped, and
we effect this object by the application of slight friction to the heads
of the wires in cither the insertion movement or in the insertion and
withdrawal movements. For this purpose the pieces forming the sides
of the grooves for guiding the heads of the wires are capable of slight
sideway movement and are borne in a direction to press to the extent
desired on the sides of the wire heads by spring or other pressure.
When the friction is desired to be applied to the heads of the wires
both for the inserting and withdrawing motions a convenient method
for the purpose is to apply the centre piece which forms one side of
each groove with slot holes for the screw or holding means to admit
of slight sideway motion in either direction, the springs in that case
acting either way. When the friction is desired for the inserting motion
only the spring. may be applied only to the bar forming the one side of
the inserting groove. India-rubber or other springs may be used. These
details may be varied.
SPECIFICATION .in pursuance of the conditions of the Letters Patent,
filed by the said George Hodgson and William Moxon in the Great
Seal Patent Office on the 9th November 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HODGSON, of Bradford, in the County of York, Machine Maker, and
WILLIAM MOXON, of No. 11, Dudley Grove, Hulme, in the City of
Manchester, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of May, in the year of our
Lord One thousand eight hundred and seventy-one, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said George Hodgson and William Moxon, Her special'
licence that we, the said George Hodgson and William Moxon, our
executors, administrators, and assigns, or such others as we, the said
George Hodgson and William Moxon, our executors, administrators, and

page_text: 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 APPARATUS EMPLOYED
IN WEAVING CARPETS AND OTHER PILE FABRICS," upon the condition (amongst
others) that we, the said George Hodgson and William Moxon, our
executors or administrators, by an instrument in writing under our or
their hands and seals, or under the hand and scal of one of us or
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 George Hodgson, on behalf of
myself and the said William Moxon, 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 thereof, that is to say :———
The improvements have reference to that class of weaving apparatus
such as for which Letters Patent were granted to William Moxon, John
Clayton, and Samuel Fearnley, dated March 21st, 1857, No. 791, in
which the movements of the pile wires for their insertion and
withdrawal are in part controlled by the heads thereof sliding in
grooves, and the object of our improvements is to prevent their
overshooting in their movement in these grooves further than for the
time desired by the action of the moving instrument when the loom is
suddenly stopped, and we effect this object by the application of slight
friction to the heads of the wires in either the insertion movement or in
the insertion and withdrawal movements. For this purpose the pieces
forming the sides of the grooves for guiding the heads of the wires are
capable of slight sideway movement, and are borne in a direction to
press to the extent desired on the sides of the wire heads by spring or
other pressure.
When the friction is desired to be applied to the heads of the wires
both for the inserting and withdrawing motions a convenient method
for the purpose is to apply the centre piece which forms one side of each
groove with slot holes for the screw or holding means to admit of slight

page_text: sideway motion in either direction, the springs in that case acting either
way. When the friction is desired for the inserting motion only, the
springs may be applied only to the bar forming the one side of the
inserting groove. India-rubber or other springs may be used.
sideway motion in either direction, the springs in that case acting either
way. When the friction is desired for the inserting motion only, the
springs may be applied only to the bar forming the one side of the
inserting groove. India-rubber or other springs may be used.
But that the Invention may be fully understood, we will by the aid
of the accompanying Drawing proceed to describe means pursued by us
Figure 1 shows an upper side view, and Figure 2 an under side view
of apparatus for guiding the heads of pile wires in the passage of such
wires into the open sheds, and then in the withdrawal of such wires
when weaving carpets and other pile fabrics according to the Invention
described under the first head of the Specification of Letters Patent
granted to the said William Moxon, John Clayton, and Samuel Fearnley
above referred to, but with our present improvements applied thereto;
Figure 3 represents a section of the parts taken through the lines 1, 1,
of Figure 1; Figure 4 is a similar section taken through the lines 2, 2,
of Figure 1; and Figure 5 in like manner represents a section of parts
through the line 3, 3, of Figure 1. In each of the Figures the same
letters indicate corresponding parts.
a represents the bottom or bed plate upon which by means of the
projecting rim a¹ and the plates b and c are formed the grooves d
and e for the guidance and support of the heads of the pile wires as
those wires are moved to and fro by their actuating instruments. The
groove d as is well understood by persons acquainted with this class of
weaving machinery is that for the traverse of the heads of the respective
wires as those wires pass into the open shed, whilst the groove e is that
for the guidance of those heads as the wires are withdrawn from the pile
of the formed fabric.
In-carrying out our improvements in place of the plates b and c being
both rigidly fixed to the bed plate a, one or the other of them is held
thereto by set screws b¹, c³, respectively, and each of these screws b³
or c³, as the case may be, passes through an enlarged hole formed for it
in the bed plate a, so as to admit of a slight play or movement sideways
of the plate 6 or c on the bed plate a, and in order that this capability
of movement may be of an elastic character to press slightly or as may
be required on the side or sides of the heads of the wires during such
b

page_text: portions of the traverse of the wires the stems of the screws 6' or c¹ are
acted on in the holes formed for them in the bed plate a by means
of india-rubber or other suitable spring f; such spring pressure may
however be otherwise applied.
Having thus described our Invention, and means which we adopt in
carrying the same into effect, we would have it understood that we do
not confine ourselves to the precise arrangement of parts shown and
described, as these may be varied, and although we have shewn both the
bars and c as being capable of movement to exert slight elastic
friction on the heads of the wires, in practice we prefer to apply such
elastic movement only to one of those bars, and by preference also to the
bar c, the other bar being a fixture as heretofore, but what we claim is,
the application of slight friction to the heads of the wires by means of
clastic pressure applied to the side or sides of the grooves in which
the heads of such wires are moved when weaving carpets and other
pile fabrics.
In witness whereof, I, the said George Hodgson, have hercunto
set my hand and scal, this Sixth day of November, in the year
