IM- PROVEMENTS IN WARPING OR BEAMING MACHINES
Year: 1872

page_text: LETTERS PATENT to Grimshaw Heyes and Thomas Entwistle, of
Accrington, in the County of Lancaster, for the Invention of "IM-
PROVEMENTS IN WARPING OR BEAMING MACHINES."-Partly a commu-
nication from abroad by Paul Wilson, of Maynard, Mass., and James
Hunter, of Manchester, in the County of Hillsborough, State of
New Hampshire, United States of America.
Sealed the 11th February 1873, and dated the 12th August 1872.
PROVISIONAL SPECIFICATION left by the said Grimshaw Heyes and
Thomas Entwistle at the Office of the Commissioners of Patents,
with their Petition, on the 12th August 1872.
We, GRIMSHAW HEYES and THOMAS ENTWISTLE, of Accrington, in
the County of Lancaster, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN WARPING OR BEAMING MACHINES," being
the result partly of a communication made to us from abroad by Paul
Wilson, of Maynard, Mass., and James Hunter, of Manchester, in the
County of Hillsborough, State of New Hampshire, United States of

page_text: America, and partly of Invention and discovery made by ourselves, to be
as follows:-
This Invention consists, first, in certain improvements connected
with the stop motion used for stopping the machine when a warp thread
is broken or absent. The threads pass through slotted pins or staples
placed in slots or grooves in a bar extending longitudinally at the front
of the machine, and below this bar there is a vee-shaped trough open
at the top and capable of being opened and closed at the bottom. The
trough is formed of two inclined plates or bars supported at their top
ends by pivots working in holes or bearings, and the bottom of one
of the plates has a curved or turned up edge, and the bottom of the
other plate a plain edge. To one of the pivots of the curved edged
plate is fixed a lever, having an inclined end in contact with the spring
handle, and the plain edged plate has vibrating or reciprocating motion
imparted to it by a lever and rod worked by a cam on the drum shaft
of the machine. When the machine is at work and all the threads are
entire, the bottom of the plain edged plate vibrates on the curved edge
of the other plate, but when a thread is broken or absent its corre-
sponding pin or staple falls to the bottom of the trough and rests on the
curved edge so that at the next movement of the plain edged plate the
obstruction of the pin will give motion to the other plate and inclined
lever, thereby moving the spring handle out of its detent, and stopping
the machine in the usual manner, further movement being given to the
curved edge plate and inclined lever by a spring or weight to allow the
pin or staple to fall into a receptacle, and also any floss or fluke that
may be collected in the trough.
The next part of this Invention consists in improved arrangements
for keeping the falling roller above the warp threads when the machine
is working in order to take the weight of the roller off the threads
and lessen the amount of breakage. To a shaft extending across the
machine are fixed two knuckle jointed levers, so placed that they can
raise the falling roller when the machine is set on by means of a chain
wheel on the shaft worked by a chain connected to the ordinary treddle.
Or instead of the chain wheel a lever or handle may be employed for the
same purpose. When the machine stops the falling roller descends to
take up the slack, the treddle moving the levers out of the way of the
shaft of the roller, but when the machine is set on the shaft passes the
levers by means of the knuckle joints, and then the levers pass under
the shaft and raise the roller from the threads.

filed by the said Grimshaw Heyes and Thomas Entwistle in the
Great Seal Patent Office on the 12th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GRIM-
SHAW HEYES and THOMAS ENTWISTLE, of Accrington, in the County of
Lancaster, send greeting.
WHEREAS Her most. Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of August, 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, givo
and grant unto us, the said Grimshaw Heyes and Thomas Entwistle,
Her special license that we, the said Grimshaw Heyes and Thomas
Entwistle, our executors, administrators, and assigns, or such others as
we, the said Grimshaw Heyes and Thomas Entwistle, our executors, admi-
nistrators, 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 MACHINES," the result partly of a communication made to us
from abroad by Paul Wilson, of Maynard, Mass., and James Hunter, of
Manchester, in the County of Hillsborough, State of New Hampshire,
United States of America, and partly of Invention and discovery made by
ourselves, upon the condition (amongst others) that we, the said Grim-
shaw Heyes and Thomas Entwistle, our executors or administrators, by
an instrument in writing under our, 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.
NCW KNOW YE, that we, the said Grimshaw Heyes and Thomas
Entwistle, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say) :—
This Invention consists, first, in certain improvements connected
with the stop motion used for stopping the machine when a warp thread

page_text: is broken or absent; and, secondly, in improved arrangements for keep-
ing the falling roller above the warp threads, when the machine is
working in order to take the weight of the roller off the threads and
lessen the amount of breakage.
These improvements will be clearly understood by the following par-
ticular description thereof, reference being had to the figures and letters
on the accompanying Sheet of Drawings, in which Figs. 1 and 2 arc
front and end elevations, and Fig. 3 a transverse section drawn to a
scale of two inches to the foot of a warping or beaming machine pro-
vided with our improvements, and Figs. 4, 5, and 6 are full sized sections
of some of the parts.
In Figs. 1, 2, and 3, a represents the ordinary end frames of the
machine; b, the warp beam; c, the drum, which gives motion to the
beam; d, the drum shaft; e, the warp threads; f, the spring handle; g,
the treadle, and the falling roller.
In the first part of our improvements the warp threads e pass through
slotted pins or staples i placed in slots or grooves j in a bar & extending
longitudinally at the front of the machine, and below this bar and pins
there are two inclined bars l, m, supported at their top ends by pivots
n, o, working in holes or bearings, so placed that the bars are open or
separated from each other at the top, and capable of being closed and
opened at the bottom, there.being at the bottom of the bar la plain
edge p, and at the bottom of the bar m a projecting edge q. To the
pivot o of the bar m is fixed a lever having an inclined end in contact
with the spring handle f, or there is an incline on the spring handle in
contact with a parallel end of the lever, and the plain edged bar has
vibrating motion imparted to it by a lovers and rod worked by a
cam on the drum shaft d. When the machine is at work and all the
threads are entire the plain edge p vibrates a short distance to and from
the projecting edge q, and there is no action on the spring handle; but
when a thread is broken or absent its corresponding pin or staple falls
between the plain and projecting edges as shewn in Fig. 4, the bar / being
in its extreme backward position so that at its next forward move-
ment the obstruction of the pin will give motion to the bar m, and the
inclined lever thereby moving the spring bandle out of its detent and a
stopping the machine in the usual manner, further movement being
given to the bar m, as shewn in Fig. 5, and inclined lever by a spring
or weight to allow the pin or staple to fall into a receptacle 10, Figs. 1
and 3, and also any floss or fluke that may be collected on the bars.

page_text: Instead of giving the primary vibrating movement to the bar it may
be given to the bar m and reciprocating movements may also be given
instead of vibrating ones.
In the second part of this Invention, which consists in improved
arrangements for keeping the falling roller above the warp threads,
when the machine is working, we extend across the machine a shaft x,
Figs. 1, 3, and 6, to which are fixed two bosses y carrying knuckle-
jointed levers, so placed that they can raise the falling roller / when
the machine is set on by means of a chain a¹ connected at one end to
one of the bosses, and at the other end to the treadle g. When the
machine is stopping the treadle rises to its highest position and slackens
the chain a', so that when the falling roller h descends to take up the
slack of the threads the shaft of the roller can pass below the levers,
but when the machine is set to work by depressing the treadle to its
lowest position, as shown in Figs. 1, 2, and 3, the shaft-passes the levers
by means of the knuckle joints, and then the levers pass under the
shaft and raise the roller from the threads to take off its weight, and
thereby lessen the amount of breakage; or instead of using the chain and
treadle for raising the knuckled jointed levers, they may be worked by a
handle or lever worked either by the treadle or by hand.
Having now described the nature and particulars of the said Invention
and the manner in which the same is to be performed we desire it to be
understood that in warping or beaming machines we claim,-
First. The vibrating or reciprocating bars in connection with an
inclined lever or its equivalent, for acting on the spring handle and
stopping the machine when the pins or staples fall by the breakage or
absence of the threads.
And secondly. The knuckle-jointed levers worked from the treadle or
by hand for raising and maintaining the falling roller above the warp
threads when the machine is at work, as such improvements are herein-
described and illustrated on the accompanying Sheet of Drawings.
In witness whereof I, the said Grimshaw Heyes, have hereunto set
my hand and seal, this Tenth day of February, in the year of our
Lord One thousand eight hundred and seventy-three.
