Year: 1860

page_text: LETTERS PATENT to William Cope, William George Ward, and Edward
Cope, of New Basford, near Nottingham, Manufacturers, for the Inven-
T
Sealed the 26th February 1861, and dated the 21st November 1860.
PROVISIONAL SPECIFICATION left by the said William Cope, William
George Ward, and Edward Cope at the Office of the Commissioners of
Patents, with their Petition, on the 21st November 1860.
We, WILLIAM COPE, WILLIAM GEORGE WARD, and EDWARD COPE, of New
Basford, near Nottingham, Manufacturers, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LACE MACHINERY," to be as
follows:-
The object of the improvements is to obtain simplicity of action with speed.
From the crank pin of a rotary shaft (at each end of the machine) a link or
connecting rod gives motion to one end of a lever, the other end of which by
another link is connected to the pin of an arm to give rocking motion thereto.
To this pin are connected other links, one back, the other front. Each of
these links is also connected to the arm of a rocking shaft, and each of these
rocking shafts is by another arm connected to one end of a separate T or three-
ended link, the opposite end of each of which is connected to an arm
די

page_text: another rocking shaft, by which these three-ended links have a sort of parallel
motion, and such that by the third end thereof to impart the required segmental
motions and alternate rests to the back and front catch bars. These T or
three-ended links are repeated at each end and across the machine according
to its width.
Also the improvements relate to the application of dividing instruments to
act upon and hold the warp threads between the guide bars or other selecting
instruments (for operating those threads) and the under side of the carriages
after each selection and whilst the carriages pass from back to front or front
to back, and thereby give time for a fresh selection of warp threads during the
traverse of the carriages.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 'filed
by the said William Cope; William George Ward, and Edward Cope in
the Great Seal Patent Office on the 21st May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
COPE, WILLIAM GEORGE WARD, and EDWARD. COPE, of New Basford, near
Nottingham, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of November, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Cope, William George Ward, and Edward Cope, Her special
licence that we, the said William Cope, William George Ward, and Edward
Cope, our executors, administrators, and assigns, or such others as we; the
said William Cope, William George Ward, and Edward Cope, 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 ex-
pressed, 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 LACE MACHINERY," upon. the
condition (amongst others) that we, the said William Cope, William George
Ward, and Edward Cope, 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

page_text: 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 we, the said William Cope and Edward Cope, 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 object of the improvements is to obtain simplicity of action with speed,.
and relate, first, to means for operating the bars which give motion to the.
carriages from back to front and front to back of the machine. From.
the crank pin of a rotary. shaft (at each end of the machine) a link or con-
necting rod gives motion to one end, of a lever, the other. end of which by
another link is connected to the pin of an arm to give rocking motion thereto..
To this pin are connected other links,. one back, the other front. Each of.
these links is also connected to the arm, of a rocking shaft, and each of these.
rocking shafts is by another arm.connected to one end of a separate T or three-
ended link, the opposite end of each of which is connected to an arm of another
rocking shaft, by which these three-ended links have a sort of parallel motion,.
and such that by the third end thereof to impart the required segmental
motions and alternate rests to the back and front bars for giving motion. to. the
carriages. These. T.or three-ended limbs are repeated at each end and. across.
the machine according to its width..
Secondly, the improvements relate to the application of dividing instruments.
to act upon, and hold the warp threads between the guide bars or other
selecting instruments (for operating those threads) and the under side of the;
carriages after each selection and whilst the carriages pass from back to front,.
or front to back, and thereby give time for a fresh selection.of warp threads.
during the traverse of the carriages..
But that our improvements may be better understood we will proceed,
aided by the accompanying Drawings, to describe means pursued by us. in
carrying, the same into effect.
DESCRIPTION OF THE DRAWINGS...
of a.
Figure 1 shows an end view of parts of a twist lace machine; with.
adaptations thereto according to our improvements;. Figure 2. shows
part.
back view of the same; Figures 3, 4, 5, 6 and 7, show parts separately.. In
each of these views the same letters of reference are employed to indicate,
corresponding parts wherever they occur.
n is the main froming the main axis receiving motion from a stoom.

page_text: engine or other power by means of a strap ör band acting upon the fixed drum
or pulley 61; 6 is a loose pulley, as is well understood; upon this axis b is also
affixed a toothed wheel' 63; which takes into another toothed wheel c¹ upon
the axis c to give motion to that axis; and this toothed wheel c', also by means
of an intermediate wheel d, gives motion to the wheel d' affixed upon the axis
e to give motion to that axis. Upon the axis c is also affixed the bevilled
toothed wheel c, which takes into the teeth of the bevilled wheel c' affixed
úpon the axis to give motion to that shaft, and thence, as required, to other
parts of the machine: Upon the face of the bevilled toothed wheel c³ is
affixed by means of a bracket the crank pin f to receive one end of the
link or connecting rod f1, the other end of which is connected to the lower
end of the lever f, which turns upon an axis of motion f³, carried by the main
framing, and at its upper end this lever f³ is connected to one end of the link
f, and the other end of this link f is forked to embrace the rocking arm
g, to which it is connected by the pin g¹; to give motion thereto, as that turns
upon the axis 9º. To the end of the rocking arm g, are also connected
by the pin g' two similar links h, and each of these links his at its other end
by pin joint connected to an arm of one of the rocking shafts i; to give
a rocking motion thereto, whilst upon each rocking shaft i, and at a slightly
different angle from the arms i, is another arm with projecting studs
to receive one end of a somewhat T-formed or three-ended link ; and the
opposite ends of these three-ended links are by pin joints ³ connected to
arms from other rocking shafts, (one at the front and another at the back
of the machine) by which these three-ended links * will have a sort of parallel
motion imparted to them, whilst the third end of each of the links is by a pin
joint connected to an arm ¹ from a catch bar j to give the required segmental
motions thereto, whilst by the combination of means, as explained, the desired
alternate rests will also be given to these bars. These catch bars are also
provided with the ordinary rollers, to run upon courses, formed as is well
understood, or with other means, to cause the blades of these barsj to catch on
to and be released from the nibs of the carriages at the times desired.
Each end of the machine is similarly provided with the moving parts ex-
plained, and the three-ended links i, with parts connected thereto, are repeated
at intervals across the machine, as may be desired, according to its width:...
J Figure 8 shows an. end view of parts of another machine; with a slight
modification of the above. In this case the rocking arm 9 receiving motion
by the link f¹ from the crank pin f is double, or has its axis of motion about
the centre thereof; and whilst the link f¹ is connected to the upper end of

page_text: the rocking arm or lever g the links h are connected by pin joints to the
lower end thereof, as shown, and each of these links his at its upper end by.
pin joint connected to an arm 7 from a rocking shaft supported in bearings
carried by the main framing, one rocking shaft being situated towards the front
and the other towards the back of the machine, and each shaft having arms
which by pin joints are connected to other arms ¹, from the respective catch
bars j:
Figure 9 shows by an end view another modification of this part of the im-
provements. In this case the pin f is affixed in a plate & affixed to the axis k
at the upper part of the machine, such axis k¹ receiving motion from the driving.
axis or shaft in any suitable manner, as is well understood. To this pin f is con-
nected one end of the link f¹; the other end of which is by pin joint connected
to an arm of the rocking lever g, which in this case is formed somewhat
L-shaped, and turns upon the axis g², whilst its other end is formed to receive
two studs g, each adapted to receive one end of a link h, the other end of
which is by pin joint connected to an arm l, and each of these arms l'is con-
nected to a rocking shaft 1¹, one towards the front, and the other towards the
back of the frame, and each of these rocking shafts l' is formed with other
arms le carrying blades 13 adapted to give to-and-fro motion to the carriages
in their combs by operating upon nibs formed in this case on the under sides
of the carriages. We prefer to form each end of the machine in each
case with corresponding parts so as to secure as much as possible unity of
action:

"
We will now describe the second part of our improvements. These are
also shown in position at Figures 1, 2, 6, and 7, and the parts separately and
to a larger scale at Figures 10 & 11, whilst a lead of dividing instruments m
is shown separately on a larger scale at Figure 12.
.
The object of this part of the improvements is the application of dividing
instruments to act upon the warp threads under the carriages after each
selection, to hold them in position whilst the carriages enter between them,
and during their traverse either from the back to the front; or from the front
to the back, as the case may be, and thus admit of employing the whole of
the time so occupied for effecting the required changes in the relative positions
of the respective warp threads by their guide bars or other operating means;
in place of being obliged, as now, to effect such changes during the short
time the centre or well of the machine is clear or uncovered by carriages
being either in the front or in the back combs. m, m, are the dividing
instruments according to this part of the improvements, and it will be scen

page_text: that they are set in leads m¹ affixed to bars m³, and we prefer to have two
sets of them, in order that whilst one set is in position to hold the threads
correctly for the carriages passing between them, the other may be in position
ready to enter so soon as the guide bars or other operating instruments have
effected the next required selection. When the carriages have passed the
threads, the dividers m; for the time forming the upper row, will be with-
drawn, and the threads will be held in position the other set of dividers;
which will now fully rise and take position for the time as an upper row,
and those just withdrawn will go into position ready to re-enter between
and space the warp threads after another selection of their relative positions,
and so on in succession. Each of these bars m³ is formed with arms m³, and
these arms m³ of the front bar m² are for these to-and-fro motions operated
by cams n upon the axis or shaft e, acting upon trucks or bowls n¹, carried by
lever arms n², affixed to a rocking shaft n³, which is supported so as to turn
in bearings carried by the main framing, and to this rocking shaft n³ are
affixed arms n', which at their upper ends are by pin joints connected to the
arms m³. The lifting and lowering motion to the front bar m² is effected by
cams o, acting upon bowls o¹, each carried by a lever o³ turning upon a fixed
axis o³ and connected by pin joint to one end of links o, the other ends
of which are connected to studs o, projecting from the bars m³. Cor-
responding motions, but at alternate times, are effected to the back bar m² by
cams or tappets p, q.. The cams p, with which the cams q, n,, and o, and parts.
operated thereby, are repeated at the opposite end of the machine, and also.
at intervals between, as may be desired, operate this back bar m² for the
to-and-fro motion thereto, by trucks or bowls p³ carried by the lever arm p
from the rocking shaft p³, having arms p connected by pin joints to the
arms m³ of that bar m², whilst cams' act upon trucks q', carried by levers q;
turning upon an axis q³, and by means of connecting rods q being connected
to studs from that bar m².
Having thus described the nature of our said Invention, and the means
we have found to answer well in carrying the same into effect, we would
have it understood that we do not claim the various mechanical parts
separately considered,, nor do we confine ourselves to the precise details, or
to the particular character of twist lace machinery as shown; but what we
do claim is,-
The adaptation or combination of means for effecting the required to-and-fro
movement of the carriages from the combined action of crank pins f, or such
like instruments and rocking arms 9, substantially as explained....

page_text: Secondly, we claim the adaptation of dividing or holding instruments for
acting upon the warp threads, in manner and for the purpose substantially as
explained.
In witness whereof, we, the said William Cope and Edward Cope,
have hereunto set our hands and seals, this Eighteenth day of
May, in the year of our Lord One thousand eight hundred and
sixty-one.
Witness,
THOMAS ROBINSON,
of New Basford.
