IMPROVEMENTS IN WARPING AND BEAMING MECHANISM
Year: 1872

page_text: LETTERS PATENT to Peter-Brimelow, of Accrington, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN WARPING AND
BEAMING MECHANISM."
Scaled the 6th May 1873, and dated the 11th November 1872.
PROVISIONAL SPECIFICATION left by the said Peter Brimelow at the
Office of the Commissioners of Patents, with his Petition, on the
11th November 1872.
I, PETER BRIMELOW, of Accrington, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
WARPING OR BEAMING MECHANISM," to be as follows:-
These improvements are applicable to the warping or beaming
mechanism for which Letters Patent were granted to me on the 18th of
December 1871, No. 3426, for "improvements applicable to the same
machine. In that Patent the weight of the slack rollers was bearing
upon the yarn. Also the stop motion which was formed of two or
more grates was liable to gather fluke, which defect however can to a

page_text: great extent be removed by placing at each end of the rail which
acrosses the machine and supports the stop motion, a centre working in
two brackets secured to the frame, the said rail being kept in its
position when the machine is working by a small lever hinged to the
rail by a pin and pressing against a bracket, which is also secured to the
machine side, so that when any fluke does accumulate the warper can
take hold of a handle which is secured to the aforesaid rail, and then
slide the small lever at one side or out of the way of the bracket, which
arrangement enables the warper to drop the stop motion to clean it.
The next improvement is an arrangement by which the weight of one
or more of the slack rollers is removed off the twist when the machine
is running. This arrangement consists of levers working on studs placed
at each side of the machine, the said levers being in contact with
tappets fastened to the treadle shaft, so that when the machine is
stopped by a pin falling, the treadle rises and the tappets push back
(while the machine is in motion) the levers which support one or more
slack rollers, so that the roller or rollers fall upon the twist and take up
the slack. The tops of the levers are formed with an incline, so that
upon the roller or rollers being wound up ready for restarting the
machine it or they run up these inclines, resting on the top of the levers.
The length of the lever is divided into, about six equal parts, and the
bosses through which the studs pass are placed about one-sixth of their
length, the other five-sixths answers as weight to bear against the roller
or rollers, and force it or them up the inclines on the top of the levers.
This could be effected by weight alone; but to diminish the bulk of the
levers I apply a spring to assist them in the last-mentioned operation.
This arrangement will be found to materially assist the warper.
My next improvement is an improved stop motion, and is arranged as
follows:-Across the machine and underneath the pins I place two or
more shafts parallel with each other, and on these shafts are secured a
number of bosses with notches in them, and on these bosses I place a
lattice, and on this lattice secure a number of bars which are set at
equal distances, so that they can drop in the notches of the bosses. On
the front shaft there is secured a V tooth wheel, and on the same shaft
is placed to run loose thereon another V tooth wheel with a spur wheel
fastened to the same, and beyond this wheel is a taper boss which is in
contact with the knocking-off lever. The last-mentioned wheel being

page_text: pressed in gear with a spring which is placed on the shaft a hoop is
then fastened to the shaft, so that the spring lies between the hoop and
the wheel, and acts as an agent for putting the V tooth wheel in gear
with its corresponding wheel, the wheels being geared up and receiving
their first motion from the drum shaft, so that it will be plain to a
practical man that when a pin falls through the breaking or absence of a
thread it will drop between the bars of the lattice, which revolve so that
when the bar comes in contact with the pin it will stop the forward
motion of the lattice, pressing the loose V tooth wheel back or out of
gear, and so bringing the thick end of the taper boss in further contact
with the knocking-off lever, which action will lead to the stoppage of
the machine. I can also have a cleaner fixed across the machine, and
arrange a bar on the lattice with a brush, so that in its revolving motion
the brushes will come in contact with the under side of the pin
holder, and clean any fluke or floss that may be there. I can also get a
close nip of the pins, which prevents any unsteadiness of the bars. As
the stop motion is formed of a lattice, and passes over two or more
shafts, I obtain a flat surface underneath the pins, which enables a
warper to place more rows of pins, as he is not confined to space.
My next improvement is a simplified rab motion. To the measuring
wheel I secure a cast-iron plate with a boss; to and on the top of this
plate is fastened a piece of iron like a half V, with the full side standing
out from the face of the measuring wheel, so that when the rab lever,
which rests on the top of the plate, comes in contact with the half V
piece of iron, it is moved laterally till it comes to the edge of the
plate, when it falls off and drops on the boss, by which action the
machine is stopped. I also use modifications of the iron bracket with the
L slot, which is described in the Specification of my former Patent. In
this modification the bracket is formed with either a T or V, a ball or a half
ball slot, so that the tension will be more equal.
I also adopt improvements of the double pin, which is mentioned in
my former Specification. In that arrangement the front pin rested upon
the thread, but in the present arrangement the back pin with the hook
rests upon the thread, and the bridge of the pins is thrown on one side,
and the front pin is cranked, the crank running across the width of the
pin, so that when the back pin is suspended on the thread the crank of
the front pin lies underneath the thread. By this alteration I obtain a
surer stoppage of the machine.

page_text: Another improvement of the double pin is that instead of the
hook I form a ring, the ring being turned outward instead of inward,
as it is with the hook, and the bridge at the top swells outward
at each side in the form of a ring. By this alteration the double or two
distinct pins is or are as well adapted for a slot as the former arrange-
ment for spanning a strip, for the swelling out of the bridge will.
prevent it or them dropping through the slot, and the ring will prevent
them jumping it or them out of place.
The next improvement is an expanding and contracting pulley for
driving the machine, so that the machine can be driven, stopped, and
braked with one pulley only. To arrive at this the rim of the driving
pulley is put together in segments, and in each part there is made a
slot; this slot begins near the centre, and runs out towards the circum-
ference of the pulley. At one or both sides of this pulley there are
plates with pins in them; the said pins fit in the slots of the driving
pulley, and convenient to these plates, which are taper on the top.
Brakes are attached to the treadle arm, so that when the lever is pushed
out of its detent by an end breaking the treadle rises and applies the
brakes to the plates which stops the plates; the pins then work in the slots,
which causes the pulley to contract or diminish in size; the strap then
looses its nip on the pulley, and the machine is stopped almost instantly.
The plates are worked back to their former position by springs, which
cause the pulley to expand again for starting. To the treadle arm,
either back or front, I place a strap fork of such angle that on the rising
and falling of the treadle arm the angle fork pushes the strap either
on the fast or loose pulley for starting or stopping the machine.
The crank of the pin can when desired be formed on the top or over
the thread, and it can be placed either on the right or left hand side of
the pins.

the 10th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
BRIMELOW, of Accrington, in the County of Lancaster, send greeting.

Patent, bearing date the Eleventh day of November, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Peter Brimelow, Her special licence that I, the said
Peter Brimelow, my executors, administrators, and assigns, or such others
as I, the said Peter Brimelow, my 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 WARPING OR BEAMING
MECHANISM," upon the condition (amongst others) that I, the said
Peter Brimelow, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 Peter Brimelow, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:
:-
This Invention relates to that class of warping or beaming machines
in which self-acting arrangements cause the stoppage of the machine
when there is breakage or absence of thread, and consists,―
First. In certain improvements added to the stop motion, so that the
same can be dropped for cleaning.
Secondly. An improved arrangement for taking one or more slack
rollers of the twist when the machine is in motion.

page_text: accompanying this Specification, and of the manner in which the same.
is to be performed or put in practice.
Figure 1 is a front elevation, and Figure 2 a transverse section of a
beaming machine provided with my improvements. Figure 3, 4, 5, 6, 7,
8, 9, 10, 11, 12, 13, and 14, are detached views of part of the same.
The first part of my improvements, which is shown at Figure 6,
consists in placing at each end of the rail I, which supports the stop
motion M, a centre marked B, the centre resting in brackets C, which
are bolted to the frame sides; E is a small lever hinged to the rail I by
the pin K; D is a bracket bolted to the frame side for the lever E to rest
against, so that the stop motion will remain in the position shown in the
Drawing when the machine is in motion; but when the warper wishes to
drop the stop motion to clean it she takes hold of the handle F, and
presses the lever E sideways, or out of the way of the bracket D; the
rail I then works on its centre B till the handle F comes in contact with
the shaft H, there will then be sufficient space between the pinholder N
and the stop motion M to allow the warper to clean it.
The second part of this Invention, namely, the improved arrangements
for taking the weight off each slack roller of the twist when the machine
is in motion, consists in placing at each end of the machine a lever or
levers similar to that shewn at D in Figure 2. The lever works on the
stud G, and is in contact with the tappet E, the tappet being fastened to
the treadle shaft K. The machine is represented as in motion with the
slack roller I in its proper place resting on the top of the lever D and
held clear of the twist O. The roller J is also clear of the twist O, so
that the friction on the twist is reduced to a minimum; but when the
machine stops through the breakage of an end the treadle H rises and
brings the full side of the tappet E in contact with the lever D at N, and
forces it up, so that the top of the lever D is moved back or out of the
way of the slack roller I, which descends to take up the slack twist.
The boss through which the stud G passes is placed about one-sixth of its
length; the remaining part of the lever assisted by the spring F answers
as a weight to bear against the slack roller I, and force it up the
incline L on to the top of the lever D, when the same is wound up by
the tension of the twist; but the principal intention in placing the boss

page_text: as described is that the warper should press the treadle down to start the
machine when the rollers are at the bottom for the purpose of facilitating
the raising of them. The lever D falls in the desired position as when
the machine is working, and so acts as an impediment to the
ascending slack rollers, such impediment in other arrangements being
sufficient to keep the slack roller still bearing upon the twist, but in this
arrangement when the roller comes in contact with the levers D, the
leverage is so great that the spring F is easily overcome, which allows the
roller to pass and take up its appointed place on the top of the lever D.
The other end of the machine has the same arrangement as the one
shown, the levers being connected so that their lifts will be equal.
The same arrangements are applicable to more than one slack roller
when required.
The third part of this Invention, which has reference to an improved
stop motion, of which a front view is shown at H, in Figure 1, consists
in placing across the machine two or more shafts with bosses on them,
the bosses being formed similar to the one shewn at A, Figure 8; these
are placed beneath the pin frame P, Figure 2; over these bosses B, the
lattice A, Figure 2, which forms an endless band is placed, and is worked
by the bars which are placed at equal distances, dropping in the notches
as shewn in Figure 8, the shaft being driven by the V tooth wheel P,
Figure 1. Behind this there is the boss C, which has a taper end, and is
in contact with the knocking-off lever L. A spring B lies between the
hoop O and the boss C, and forces the V tooth wheel P into gear with
its corresponding wheel A, by which means the lattice is driven.
So it will be evident that if a pin falls through the breaking of a
thread, the lower end of the pin will fall between the bars, and stop the
forward motion of the lattice, which will cause the V tooth wheel P,
Figure 1, to slide back, and push the thick end of the taper boss C
against the knocking-off lever L which pushes it out of its detent N, and
so leads to the stoppage of the machine.
The bars are arranged on leather or any suitable and flexible material,
though they may be arranged on chains similar to those shown in
Figure 10, which represent two links in connection, B being adapted
for a boss similar to A, Figure 8; and C is formed with a tooth R, and
is better adapted for an ordinary chain pulley. A and B, Figure 9, are

page_text: different forms of bars that may be used to form the stop motion. Thus
it will be seen that the same principle may be modified to a great extent
without departing from its essential character; and further I have to
remark that in regard to this improved stop motion I do not claim the
causing of bars to revolve as that has been done before, though they
revolved in a circle, but what I do claim in regard thereto is arranging
the bars as a lattice and carrying them round two or more shafts,
whereby I obtain a flat surface underneath the pins as shewn at A in
Figure 2, which gives greater capacity for production as there is more
space to increase the number of rows of pins. I also obtain a close and
straight nip of the pins which prevents unsteadiness in the bars.
different forms of bars that may be used to form the stop motion. Thus
it will be seen that the same principle may be modified to a great extent
without departing from its essential character; and further I have to
remark that in regard to this improved stop motion I do not claim the
causing of bars to revolve as that has been done before, though they

whereby I obtain a flat surface underneath the pins as shewn at A in
Figure 2, which gives greater capacity for production as there is more
space to increase the number of rows of pins. I also obtain a close and
straight nip of the pins which prevents unsteadiness in the bars.
Further, I obtain the following advantages, namely:-
(1.) The stop motion is direct.
(2.) It will clear away its own fluke as the lattice is continually
revolving. Morcover to any bar a brush can be added which in its
motion will clean the pin holder. A cleaner can also be added which
goes across the machine and is kept in contact with the bars of the
lattice to clean them.
(3.) The boss A, Figure S, being divided into six equal parts revolves
twice while the drum R, Figure 1, is revolving once. Each bar strikes
every twelfth revolution of the drum, and so on in proportion as the
bars are increased or diminished in number without any additional
speed, so that the stoppage of the machine is almost instant.
A, Figure 4, is a front and side view of an improved double pin, the
back pin with the hook which prevents the pins from jumping out of
its place rests upon the thread, and the bridge P of the pin is thrown
on one side. The front pin F which acts upon the stop motion is of a
similar form to the one shewn; the bent part C lies under or over the
thread when the back pin is suspended, which alteration in the pin
secures complete stoppage of the machine.
B, Figure 4, is a front and side view of another double pin which is
adapted for a slot, as shewn in Figure 6; N being a part of the pin frame;
P, the pin; A, the ring which prevents the pin from jumping out of
the slot; S, the part which acts upon the stop motion when the pin falls
through the breaking of a thread, the pin being prevented from falling
through the slot by the ring at the top.

page_text: C and D, Figure 4, are front and side views of single pins, which
posess to a great extent the same principles as the pins A and B, and
are modifications of them. The pin D is shown suspended on its thread
with a thread at each side of it, the projections P being underneath these
threads and preventing the pin from jumping off its thread or out of the
slot of the pin frame. The pin C is represented having jumped, the
projections P having come in contact with the threads, and as the slot A
through which the pin is thread lies below the projections P the pin is
quite safe from jumping out of its place. The pin D is thread at the
bottom A, C being hinged to it, which covers up the opening after the
pin is thread. E is a pin with two stems, and is used where the slots in
the pin frame are required to be wide to allow the fluke and dirt to fall
through. The stems prevent the pin from twisting and getting fast
after the body of the pin has fallen in the slot. The pins C, D, and E
are prevented from falling through the slots by the form of the pins
at O, so that the stoppage is placed at the bottom instead of at the
top.
The letters A, Figure 3, show different forms of the improved bracket,
in which the bars are slided to form the pin frame. The improvement
consists in placing a projecting piece at each side of the centre, so that
the tension will be equal on the bars, which is shown at S, Figure 1.
The fourth part of the Invention, which relates to the motion for
stopping the machine at the end of each wrap of warp, consists of the
following arrangements:-To the measuring wheel A, Figure 5, I secure
the cast-iron plate H, which has a boss O projecting from it; on the
top of this plate I secure the half V I, which gives the wrap lever Ba
lateral motion until it comes to the edge of the plate, when it falls off,
receiving its ordinary vertical motion on the boss O, which causes the
stoppage of the machine. The wrap lever B falling on a smooth boss
in contradistinction to falling in an indent is not liable to work itself
fast and break the wheels in case the warper should neglect to lift the
wrap lever and put it in its appointed place on the top of the half V.
At the end of each wrap of warp I also place the half V on the top
of ring C, Figure 5, when required; the ring being held by the friction
of the plate H sufficiently tight to perform its office, and yet easy
enough for the warper to turn it by hand, so that when she wishes to
mark the warp or to warp different lengths slic has only to place the

page_text: half V where required and the lever will wrap at its proper time without
the attention of the warper.
The fifth part of this Invention has reference to the driving and
stopping of the machine, and consists of the following arrangements :-
At Figure 13 is a front view of an expanding and contracting pulley
placed on the drum shaft H; B, the segments of the pulley, Figure 14,
one of the levers by which the pulley is expanded and contracted; A,
working in a groove of the pulley B, is acted upon by the quadrants B,
Figure 12, which begin near the centre and run out towards the circum-
ference. A, Figure 13, a stationary plate which acts as a brake when
the pulley is expanded by the pressure of the foot on the treadle N,
Figure 12, but is better shewn at B, Figure 11; it tightens the strap
which starts the machine, but when the machine stops through the
breaking of a thread, the pulley contracts and comes in contact with the
plate A, which forms a quick and silent brake, so that the machine is
driven, stopped, or braked by one pulley.
Figure 11 is another view of the pulley; P, are eccentrics; N, levers
secured to them; A, a plate connected to all the levers N, and secured
to the treadle B; O, are plates which fit in the groove of the segments,
and in which the eccentrics P work, so that the rising and falling of the
treadle expands and contracts the pulley for starting or stopping the
machine.
Figure 7 is another means, and is a modification of an expanding and
contracting pulley for tightening and slackening the strap by which the
machine may be driven; B, B, two conical pullies; I, I, cover the space
between the pulleys, and prevent the strap from getting between A,
which is secured to the treadle; C, is one of the means by which the
pulleys are brought together, which tightens the strap N to start the
machine. Or the pulley on the left hand might be parallel with a
flange, and run loose on the drum shaft; the parts I are then dispensed a
with, and the strap which would be half and half, as shown, would be
continually running on this pulley and kept tight; but when the pulleys
were brought together by A, the strap would nip the conical pulley,
which is fast to the drum shaft and start the machine. To complete the
arrangement, I secure to the treadle C one half of the strap fork E,
Figure 1, so that on the rising of the treadle it would press the loose

page_text: pulley back away from the conical pulley, and also answer as a guide to
keep the strap on the pulley.
The strap fork E, Figure 1, which is secured to the treadle G or any
convenient part of the same according to the different positions of the
strap V, is used in connection with an ordinary fast and loose pulley, and
is the means of throwing the strap from one pulley to the other by the
vertical motion of the treadle, which arrangement being direct produces
a quick delivery of the strap from the fast to the loose pulley, the brake
being applied at the other side of the machine. D is a stationary plate,
and held by the cast-iron strap F; T is secured to the drum shaft and
revolves with it when the machine knocks off through the breaking of a
thread, the plate D is brought in contact with the plate T, which causes
a quick and silent brake. C, in Figure 2, represents two bars which go
across the machine, and are used when required to prevent the lumps
in the twist passing on to the beam, one of which is shown to be stopped;
the top bar is secured to the frame sides by small levers, so that it can
be raised from the twist either mechanically or by hand when required;
or instead of two bars one may be used, formed like a comb, the teeth
being short and stiff, so that they will not yield to the twist. This will
also keep the ends straight, and prevent broken ends snarling and
twisting round the pins.
Having now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
herein-described Invention of "Improvements applicable to Warping or
Beaming Mechanism," wherein the following are special and important
features:-
First. The herein-before described improved added to the stop motion,
enabling the same to be dropped for cleaning.
Secondly. The improved arrangement, herein-before described, for
taking one or more slack rollers off the twist when the machine is in
motion.
Thirdly. The improved stop motion, herein-before described, whereby
I obtain a flat surface underneath the pins, which gives greater capacity

page_text: Fourthly. The improved pins, herein-before described, which act on
the stop motion, together with the improved bracket, whereby equal
tension is applied to the bars which are slided in it to form a pin
holder.
Fifthly. The improved wrap motion, herein-before described and illus-
trated by the accompanying Drawings.
Sixthly. The application of the improvements, herein-before described,
for driving and stopping the machine, together with the angle strap fork,
which throws the strap from one pulley to the other by the vertical
motion of the treadle.
In witness whereof, I, the said Peter Brimelow, have hereunto set
my hand and seal, this Seventh day of May in the year of our
Lord One thousand eight hundred and seventy-three.
