Machine Maker, and Samuel Cook, junior, of the same Place, Machine Maker,
for an Invention of "IMPROVEMENTS IN SELF-STOPPING WARPING OR BEAMING
MACHINES."
PROVISIONAL SPECIFICATION left by the said Samuel Cook and Samuel
Cook, junior, at the Office of the Commissioners of Patents on the 13th May
1881.
SAMUEL COOK, senior, of Bury, in the County of Lancaster, Machine Maker,
and SAMUEL Cooк, junior, of the same Place, Machine Maker. "IMPROVEMENTS IN
SELF-STOPPING WARPING OR BEAMING MACHINES."
The object of these improvements is to simplify the stopping motion on self
stopping warping or beaming machines, and to make its action more effective and
certain when a thread of the warp breaks or is missing.
For this purpose we fix a shaft across the warping machine, to which shaft
motion is given in the usual way, it being held in gear by a clutch box with V or
inclined surfaces.
On the same shaft we key or fasten a number of wheels which have slots formed
on their peripheries. An endless chain is provided, each alternate link of which
has paps or projections protruding on each side, these projections dropping into the
slots on the rims of the wheels, which in revolving thereby give motion to the
endless chaiu. On the latter are rivetted a number of flat bars in an open lattice
form; on the inside of this lattice we fix brackets with flat surfaces which keep the
chain perfectly flat whilst passing underneath the pin holder. When a thread
breaks or is missing the pin falls down and comes in contact with one of the flat
bars which stops the forward motion of the endless chain and forces the V or
inclined clutch out of gear at the end of the machine; this pushes an upright lever
out of its indent and stops the machine.
Another improvement is to take the weight of one or more of the slack rollers
off the yarn when the machine is running. This has been previously attempted to
be done by levers acted upon by tappets or cams fastened to the treddle shaft,
which has proved inefficient, as when the machine is stopped both the rollers were
thrown upon the twist at the same time, which was a great defect.
By our new arrangement this difficulty is overcome by the back roller always.
arriving at the bottom first before the second roller moves. On arriving at the
bottom it strikes the end of the levers, which causes them to move upon their
pivots and put the second roller into action, and the second the third, the object
being to have the weight of one roller only on the twist at the same time.

SELF-STOPPING WARPING OR BEAMING MECHANISM."
The object of these improvements is to simplify the stopping motion on self
stopping warping or beaming machines, and to make its action more effective and
certain when a thread of the warp breaks or is missing.
For this purpose we fix a shaft across the warping machine, to which shaft
motion is given in the usual way, it being held in gear by a clutch box with Vor
inclined surfaces. On the same shaft we key or fasten a number of wheels which
have slots formed on their peripheries. An endless chain is provided, each alternate
link of which has paps or projections protruding on each side, these projections
dropping into the slots on the rims of the wheels, which in revolving thereby give
motion to the endless chain. On the latter are rivetted a number of flat bars in-
an open lattice form, and on the inside of this lattice we fix brackets with flat
surfaces which keep the chain perfectly flat whilst passing underneath the pin
holder. When a thread breaks or is missing the pin falls down and comes in
contact with one of the flat bars, which stops the forward motion of the endless
chain and forces the V or inclined clutch out of gear at the end of the machine;
this pushes an upright lever out of its indent and stops the machine.
Another improvement is to take the weight of one or more of the slack rollers
off the yarn when the machine is running. This has been previously attempted
by levers acted upon by tappets or cams fastened to the treadle shaft which has
proved inefficient, as when the machine stopped both the rollers were thrown upon
the twist at the same time, which was a great defect.
By our new arrangement this difficulty is overcome, the back roller always
arriving at the bottom first before the second roller moves. On arriving at the
bottom it strikes the end of the levers, which causes them to move upon their
pivote and put the second roller into action, and the second the third, the object
being to have the weight of one roller only on the twist at the same time.
And in order that our said Invention may be well understood, we shall now
proceed more particularly to describe the same, reference being made to the
accompanying Sheet of Drawings, like letters of reference indicating corresponding
parts in all the Figures.
Figure 1 is an end elevation of our improved self-stopping warping or beaming
machine; Figure 2, a front elevation of the same, and Figures 3 to 5 detailed
views of parts of Figures 1 and 2.

number of star or slotted wheels d, motion being given to the shaft b by the
grooved pulley e. On the other shaft c which is stationary are fixed a number of
specially shaped brackets f corresponding in number with the star or slotted
wheels d and perfectly flat on their top sides for the purpose of keeping the
lattice a level or in line when passing under the knocking off pins g. These
brackets are so constructed as to lock both the shafts b and c together, and thus
form a complete and unbroken circuit on which the endless chain a¹ travels.
The latter is stretched around the brackets fand is composed of peculiarly shaped
links, each alternate link having projecting paps or pivots on the sides which

page_text: drop into the slots on the peripheries of the star wheels d, and by this means
motion is given to the lattice a; this is composed of light bars i of iron or steel
(Fig. 4) firmly rivetted on to the endless chain a', which when the machine is in
motion is constantly revolving underneath the bars j which carry the knocking off
pins g, as shewn in Fig. 3; the drop pins g are suspended by the yarn over the
three flat bars j, and the lattice motion a is driven by the grooved loose pulley e
gearing with its tapered nose into the bowl k, which is made to slide on its shaft b
by means of a key 7 let into the shaft b, and is kept close to the loose pulley e by
the small elbow lever m provided with a weight n for enabling it to receive
motion from the pulley e. When an end breaks (see middle pin, Fig. 3) the pin g
drops onto the flat bar j and immediately stops the lattice motion a; the pulley e
being loose on its shaft b slides out of the bowl k against the vertical lever o,
thereby knocking the latter off its rest p, when the weight at once pulls up the
treadle q thus releasing pulley r from the friction plate s and stopping the
machine.
The machine is driven by friction as follows:-On the end of the drum shaft we
fasten the friction plate 8 formed with flat surfaces turned perfectly true, and on
the same shaft we set the plate pulley with turned flat surfaces corresponding
with the surfaces on the friction plate s; this pulley r runs loose upon the drum
shaft, and to keep it in contact with the friction plate s we apply a saw tooth
coupling t, one half of which is cast on and forms part of the step of the drum
shaft, the other and corresponding half being cast on the treadle lever. The
driving pulley is kept in contact with the frictional plates as long as the vertical
lever o is on its rest p, but when this is disturbed by the breaking of a thread or
from any other cause, a pin g drops, which stops the revolving lattice a and liberates
the saw tooth coupling t, and this breaks the contact of the driving pulley with
the friction plate s and stops the machine.
Another improvement consists in taking the weight of one or more of the slack
rollers off the yarn when the machine is running, which has been previously
attempted by tappets or cams, but unsuccessfully.
According to our present arrangement this difficulty has been overcome by the
application and use of two vertical levers u, one on each side of the machine, which
oscillate on a shaft extending across the machine and carried in bearings at each
end; these levers u are curved or have a quadrant at their bottom end and have a
flat bearing at the top for carrying the slack rollers v, v¹, when the machine is
running, but when an end breaks or is missing the back slack roller v¹ descends to
take up the slack yarn, and on arriving at the bottom it strikes the curved end of
the lever u and causes it to fall forward and liberate the front slack roller v to
take up the remaining slack yarn.
When the machine is again started the back roller v¹ comes up to the top first
and liberates the vertical levers u, which fall into their original position ready to
take hold of and retain the front roller v as soon as it arrives at the top, so that
the weight of one roller only rests upon the yarn at one time, this being a matter of
great importance in beaming fine and tender yarns.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, we desire it to be understood that what we
consider novel and original and therefore claim as our Invention is,-
1. The construction and arrangement of lattice motion mounted on two shafts in
combination with the star wheels and peculiarly shaped brackets to keep the chain
level when passing underneath the knocking off pins, substantially as shewn and
described.
2. Forming the endless chain with links having projecting paps or pivots on the
sides to work into the slots on the star wheels, substantially as shewn and
described.
3. The construction and use of the saw tooth coupling in combination with the
treadle motion for starting and stopping the machine, substantially as shewn and
described.

page_text: 4. The arrangement of vertical levers with curved or quadrant bottom ends for
liberating the slack rollers and causing them to drop into action at the proper
time, substantially as shewn and described.
5. The general arrangement of machinery or apparatus, substantially as described
and illustrated by the accompanying Drawings.
In witness whereof, we, the said Samuel Cook, senior, and Samuel Cook, junior
have hereunto set our hands and seals, this Nineteenth day of November
in the year of our Lord Eighteen hundred and eighty one.
