Year: 1862

page_text: LETTERS PATENT to James Redgate, of Sneinton, in the County of
Nottingham, Lace Manufacturer, and Herbert Redgate, of Stoney
Street, in the Town and County of the Town of Nottingham, Lace
Manufacturer, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR THE MANUFACTURE OF FABRICS ON BOBBIN NET OR TWIST
LACE MACHINES."
Sealed the 21st January 1868, and dated the 25th July 1862.
PROVISIONAL SPECIFICATION left by the said James Redgate and
Herbert Redgate at the Office of the Commissioners of Patents, with
their Petition, on the 25th July 1862.
We, JAMES REDGATE, of Sneinton, in the County of Nottingham, Lace
Manufacturer, and HERBERT REDGATE, of Stoney Street, in the Town and
County of the Town of Nottingham, Lace Manufacturer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR THE MANUFACTURE OF FABRICS ON BOBBIN NET OR TWIST LACE
MACHINES," to be as follows:-
Our improvements relate to the arrangement of machinery or apparatus
which is applicable to the "circular," "Lever's," and "single and double-locker
machines," and consists of a bar in or upon which is secured a number of
instruments, each of which is somewhat thicker in depth than in width; or
these instruments may be cast in leads, and secured to the bar in the well-

page_text: known way. Each instrument has a slot in the direction of its depth pro-
ceeding from the upper side thereof, in this slot is a thin bar, which is
provided with a knife edge on its lower side, and is free to move end wise, and
also upwards and downwards, such movements being effected by a contrivance
for that purpose at one or both ends of the machine. The number of instru-
ments we use at a given time will vary; sometimes we use an instrument at
every point in the back point bar of the machine, or we use any less number
according to the fabric intended to be made; these instruments we lower to
a certain depth, and we bring the front and back point bars in their turn
upward between these said instruments, and we place one, two, or more warp
threads in front of the centre of the machine, and the requisite number for
making the fabric at the back of the centre of the machine; the threads in
front as they are traversed to the right and left are taken up by the point bars,
one or more such warp threads passing round one or more of the before-
mentioned instruments, and passing round also one or more of the bobbin
threads to form a looped pile on the face of the fabric. When we wish the
pile to remain uncut, we use these said instruments without a knife, and cause
them to be brought slightly forward at the same time as they rise out of the
pile, when the instruments again descend ready for forming another series of
piles. But when we desire to form a cut pile on the fabric we dispense with
the forward and upward movements of the instruments, and keep them
stationary, using the knife, to which we communicate motion as above
described, so that as the pile is formed, and the work is carried up to the work
beam, the knife will cut the pile and free the work from the instruments, in
either case we sometimes shog the instrument bar to the right and left one or
two gates, according to the fabric required to be made and the number of
instruments used.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Redgate and Herbert Redgate in the Great Seal
Patent Office on the 24th January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
REDGATE, of Sneinton, in the County of Nottingham, Lace Manufacturer, and
HERBERT REDGATE, of Stoney Street, in the Town and County of the Town of
Nottingham, Lace Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent; bearing date the Twenty-fifth day of July, in the year of our Lord.

page_text: One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said James Redgate and Herbert Redgate, Her special licence that
we, the said James Redgate and Herbert Redgate, our executors, adininis-
trators, and assigns, or such others as we, the said James Redgate and
Herbert Redgate, 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
MACHINERY OR APPARATUS FOR THE MANUFACTURE OF FABRICS ON BOBBIN NET
OR TWIST LACE MACHINES," upon the condition (amongst others) that we,
the said James Redgate and Herbert Redgate, our executors 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 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 Putent.
'
NOW KNOW YE, that we, the said James Redgate and Herbert
Redgate, 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, reference being had to the
accompanying Drawings, and to the letters and figures marked thereon, that
is to say:-
Our Invention relates to improvements in or applicable to the machinery or
apparatus known as the circular, the Lever's, and tho single and double-locker
machines, and consists in an improved arrangement in which we employ a bar,
in or upon which is secured a number of instruments, each of which is some-
what thicker in depth than in width; or these instruments may be cast in
leads, and secured to the bar in the well known way. Each instrument has a
slot in the direction of its depth proceeding from the upper side thereof; in
this slot is a thin bar, which is provided with a knife edge on its lower side,
and is free to move endwise and also upwards and downwards, such move-
ments being effected by a mechanical contrivance for that purpose at one or
both ends of the machine. The number of instruments which we use at a
given time will vary; sometimes we use an instrument at every point in the
back point bar of the machine; or we use any less number that may be
required according to the fabric intended to be made. We lower these

page_text: Figure 5, Sheet 3, shows the apparatus as applied to a Lever's machine
when we use a number of the instruments, such instruments being moved up or
down simultaneously. In this Figure, the instruments are shewn lowered; and
in Figure 6, Sheet 3, the same instruments are shown in a raised position;
the last two Figures are in section.
A front view of the instruments as lowered, with the apparatus for raising
the same, is shewn at Figure 7, Sheet 4. The corresponding parts in Figures
1, 2, 3, and 4, are lettered alike; the corresponding parts in Figures 5, 6,
and 7, are lettered alike.
In Figures 1, 2, 3, and 4, Sheets 1 and 2, A represents a bar which is fixed;
a number of instruments B, are secured upon this bar by means of a pin or
rod C held by a comb C', screwed to the upper edge of the bar A, and the
instruments B are also secured by a thin bar D held by a comb D' screwed to
the lower edge of the bar A. The rod C acts as an axle, upon which the
instruments turn, and the thin bar D acts as a guide, upon which the instru-
ments slide; the inclination of the bar D causing the instruments to be slightly
advanced as they rise upwards; the instruments are slotted to allow of such
movements. In these arrangements we employ one instrument to every point
in the back point bar of the machine, or any less number that may be required
according to the fabric to be made; these instruments are somewhat thicker
in depth than in width, we lower them to a certain depth, as shown at Figure 1,
and in order to insure the lowering of the instruments we use a bar E, to which
motion is communicated by a cam through levers E', E'. When the bar E has
driven the whole of the instruments down, it is immediately raised, and a
selection of the instruments is made, those instruments which are not required
to be used are pulled up by the rising of a jacquard, each instrument being
connected to this jacquard by a string or other equivalent contrivance. When
the selection has been made, we bring the front and back point bars F, F, in
their turn up between the said instruments, and place, one, two, or more warp
threads in front of the centre of the machine to make the looped pile, and we.
place the requisite number of warp threads for making the fabric at the back
of the centre of the machine, the threads in front as they are traversed to the
right and left, are taken up by the point bars, one or more of such warp
threads passing round one or more of the instruments, and also passing round
oue or inore of the bobbin threads to form a looped pile on the face of the
fabric. We use the arrangement shown in Figures 1, 2, and 3, when we
wish the pile to remain uncut. When the machine has made the required
number of pile loops, all the instruments are raised to the position shewn in.
Figure 2.
All the instruments are again brought down by the Lar E, and a

page_text: fresh selection is made by the jacquard when the above movements are
repeated.
In Figure 1, Sheet 1, G represents the work, (this bar is also seen in
Figures 1, 2, 3, and 4); H, the work roller, (this roller is also seen in
Figures 1 and 4); I, I, the carriages; J, J, the driving bars; K, K, the
combs; L, L, the comb bars; and M, M, the locker bar; T are the guide bars
which are moved in any of the usual ways. When we desire to form a cut
pile on the fabric we dispense with the forward and upward movements of the
instruments for the purpose of freeing them from the loops, keeping them
stationary after a selection has been made; and we use a bar N, seen on
Figure 4, which bar has a knife edge on its lower side, and is free to move
endwise, and also upwards and downwards, such movements are effected by
suitable mechanical contrivance at one or both ends of the machine; the
knife bar is held in brackets O, screwed to a bar P, held by arched brackets Q,
screwed to a spindle rod R lying in bearings S; the spindle rod is caused to
oscillate by a cam and levers, whereupon the brackets O will lift the knife clear
out of the slots in the front of the points of the instruments B, until a selection
of the instruments shall have been made by the jacquard, when the knife will be
again lowered and a pile formed upon the fabric, and as the work is carried up
by being wound upon the work roller, the said pile loops will be cut by the
lower edge of the bar N. Thus by these arrangements we can make either
a looped pile or a cut pile on the face of the fabric, and on any part of such
fabric at discretion, the looped pile or a cut pile being made simultaneously
with the fabric on which such piles are being made. When we require a set
pattern and wish to dispense with the use of a jacquard, we use the arrange-
ment shewn at Figures 5, 6, and 7, Sheets 3 and 4, as applied to a Lever's
machine. A represents a bar, to which are screwed a number of leads in
which the instruments B are cast; the number of such instruments varies
according to the pattern required. This bar A is secured to two or more
pendent arms C, which are slotted near their upper and lower ends, so that
they may slide vertically on the pins C, C, in the upper and lower ends of the
brackets D, which may be secured to one of the tie bars or other rigid part
of the machine; the brackets D are further strengthened and stayed by a
horizontal bar E, to which they are secured; at the back of each bracket D,
springs F are screwed, the springs passing round to the front and pressing at
their lower ends on the pendent arms C, the upper ends of which are provided
with trucks G; below the trucks lies a bar H provided on the upper side with
wedge-shaped inclines I there are as inany such inclines as there are brackets D
the bar is moved horizontally the requisite distance by a lever Kte the upper

page_text: end of which it is attached.
This lever K works at its lower end on a pin L,
and is moved by a wire or cord M worked by a jacquard or other equivalent
contrivance, the bar and inclines are moved back again by means of a spring at
the other end of the bar. At the bottom of each bracket D are inclined
pieces N placed vertically, up which the bar A slides when it is lifted by
moving the wedge pieces under the trucks; thus the instruments secured to
the bar A will have a horizontal movement outwards at the same time as they
are moved upwards, by which means they will be the more easily taken out of
the pile loops made on them, as described in the previous arrangements.
In Figures 5, 6, and 7, as far as they are alike, O, O, represent the point
bars; P, is the work bar; P, the work roller; Q, Q, the catch bars; R, the
carriage; S, S, the landing bars; T, T, the comb bars; U, the combs; V, the
guide bars moved in either of the usual methods in which guides are moved.
Although we have described the employment of our Invention in its applica-
tion to a Lever's machine, and a double-locker machine only, we would have
it distinctly understood that our said Invention is applied in like manner, both
to a circular machine and, a single-locker machine.
Having now described the nature of our said Invention and in what manner
the same may be performed, we declare that we claim as our improvements in
machinery or apparatus for the manufacture of fabrics on bobbin net or twist
lace machines, the employment or application of the instruments and bars
arranged, combined, and operating substantially as described.
In witness whereof, we, the said James Redgate and Herbert Redgate,
have hereunto set our hands and seals, this Twenty-second day of
January, in the year of our Lord One thousand eight hundred and
sixty-throo
