"IMPROVEMENTS IN WARPING OR BEAMING MACHINES.'
"
This Invention relates to warping or beaming machines, having self acting
stopping motions for stopping the machines when one or more of the warp threads
break, and consists in various improvements for enabling this object to be attained
with greater simplicity and economy than heretofore. The Invention is especially
applicable for coloured work, the object being to put a greater number of ends in
less space between the flanges of the beam than heretofore when using expanding
and contracting reeds and combs.
This Invention consists, first, in employing in connection with pins or detectors
which are supported by the warp threads, one or more stationary rods or wire,
angle or T iron being used, and by the application of levers and springs, the rods,
wire, angle, or T iron being worked vertically, horizontally, or in a curve to enable
the operator easily to get a detector off the detector bar when a thread is broken.
When flossy material is used, angle or T iron is used and worked vertically,
horizontally, or in a curve, and when the machine stops for a piecing up, the angle
or T iron, by the action of levers, is taken in such a position as to allow the operator
more easily to get at the detectors and piece the threads. When the material is
not flossy, stationary bars, rods, or wires are sufficient, and do not allow a detector
to come in contact with the oscillating bar and stop the machine. Secondly, in
making the pins of round wire without the twist at the upper end, as is now
customary, so that there can be a greater number of threads in a less space than
heretofore. The angle or T iron or gutter iron is used for the purpose of taking or

page_text: pushing floss from the detectors and detector bars each time the machine stops; one
side of the angle or Tiron moves by the action of levers and springs down by the
side of the detectors and bars, and pushes the floss off them every time the machine
stops, and keeps them clean so as not to allow the detector to be held up by
accumulated floss. The angle, T, or gutter iron is moved below the level of the
detector bar or bars so as to enable the operators to easily get at the detectors with
their fingers.
The third part of my Invention relates to the self stopping motion, and consists
in working from a drum or driving shaft levers secured to a shaft in the frame,
and at the top of the levers is secured wire, bars, or cat gut, or similar material,
which comes in contact with the detector when the thread is broken and stops the
machine. There is a connection from the drum or driving shaft to the oscillating
bar shaft by a lever or rod and spring secured to the lever on the oscillating bar
shaft, the spring which is worked in conjunction with the lever and oscillating bar
rods, yields or gives way when a thread is broken or absent, and allows one end of
a jointed lever to fall which is held up when a thread is entire, but when a thread
is broken, the one end of the jointed lever with double catch falls in position when
working in one direction, and removes the setting or spring out of its detent, and
stops the machine; in the opposite motion of the bar when a thread is broken, tho
end of the jointed catch lever falls in position, and comes in contact with a lever or
a stud, and motion being given to the lever, it moves the setting on spring out of
its detent, and stops the machine.
The fourth part of my improvements consists in coloured warp beaming for
enabling short lengths of warps to be worked advantageously for coloured material,
dispensing with the old style of warping mill which has no stopping arrangement,
and for warping a greater number of ends or threads with expanding reeds and
combs than has heretofore been done; by using expanding and contracting reeds,
and variable width of beans for warps can be used. The front expanding reed
dents are made ont of round wire dents with elongated slots at both ends, with an
eye in the middle of the dents for threads to go through; the lease of the warp is
got by this expanding reed at the end of each warp, or at any part of the warp.
The frame for expanding the front reed works in slots of brackets secured to the
front of the machine; a shaft with eccentrics or cams is worked in these brackets
under the expanding reed frame; when the machine is working threads run through
eyes in expanding reed dents; when the lease is to be taken, the eccentrics or
cams are turned by a handle, the threads in the eyes of the dents being taken down,
and the threads at the sides of the dents remain in the ordinary position, the lease
band being put through between the ends. The eccentrics or cams are turned in
opposite directions when the threads in the eyes aro lifted upwards, the threads at
the side of the dents remain in their ordinary position, and the lease bands being
put between the warp threads.
The fifth part of my improvements relates to the framing of the front expanding
reed, which is made of small hinged rods of iron serrated like a saw, and at each
end of the round wire dents are elongated slots slided on to small serrated rods of
iron at equal distances. These are arranged in the framing to be worked with
right and left handed screws, and as the small hinged rods are closed by turning
the right and left handed screws, the angles of the rods become more acute, and
the dents and threads occupy less space and the dents and threads occupy more
space as the angle of the rods are made more obtuse; I increase the number of
hinged rods according to the number of ends required. In arranging a greater
number of ends in little space in the back expanding reed, the dent ends are
made parallel with each other, the other portion of the dent is made at an angle to
the ends, the ends having springs as arranged in the expanding back reeds commonly
used; by this arrangement of dents, several threads can work between two dents,
and the threads are more equally divided, and a good sheet is obtained. Near the
back expanding reed I place a number of glass or iron rods or rollers between the
reed cap and the reed case to divide the threads.

page_text: The sixth part of my Invention consists in dividing the beam into sections, and
also in an improved framing for the beam to work in. One sort of sectional beam
being divided into a number of parts, and made in the following manner :-A
flange is secured at or near the end of the ways, and if a beam, say, 30 inch, is
wanted, I divide it into 5 parts. After securing No. 1 flange at or near the end of
the beam, a shell of wood is put on the beam close against No. 1 flange, the shell is
secured to the beam, No. 2 flange is put against No. 1 shell, and secured to the
shell, and so on. There is a frame arranged in front of the self-stopping machine,
and when one section of the beam has sufficient warp on the beam, is slided on
parallel bars to the next section, the gearing for driving the sectional beams is
arranged to slide on bars with gibbed keys. It will be seen as the quantity of
warp increases on the beam, the warp or thread is drawn through the machine at
variable speeds; to obviate this and draw warp or thread at a more uniform speed,
I use cone drums or a friction plate and bowl which I regulate by a worm and
wheel.
The back expanding reed is placed in a movable frame at the back of the
machine, and its position can be altered to different angles to allow more ends to be
got in the same space.
The seventh part of my improvements relates to improved pins or detectors
which are inuch simpler than those hitherto made out of round steel wire, and are
for the purpose of getting a greater quantity in less space, any number of detector
bars may be used, according to the number of threads required in the warp. I
make my improved pins with a straight end at the top instead of twisted; I also
use in front of the expanding front reed an expanding comb when required; I also
make an improved detector stamped or punched out of sheet metal, and leave the
foot part or bottom solid, and those made out of round wire are brazed or fastened
at the bottom, making them much stronger; another sort of improved pin I make
with a neck at one side of the eye, doing away with the necessity of using a hook
for drawing a thread through the detector, or taking the detector off the detector
bar, and replacing it on the detector bar.

"IMPROVEMENTS IN WARPING OR BEAMING MACHINES."
This Invention relates to warping or beaming machines, having self acting
stopping motions for stopping the machines when one or more of the warp threads
break, and consists in various improvements for enabling this object to be attained
with greater simplicity and economy than heretofore. The Invention is especially
applicable for coloured work, the object being to put a greater number of ends in
less space between the flanges of the beam than heretofore when using expanding
and contracting reeds and combs. And in order that my Invention may be under-
stood, I will describe the accompanying Sheet of Drawings. Figs. 1 and 2 are side
views in section of parts of a warping machine to which my improvements are
applied. a, a, are pins or detectors which are supported by the warp threads.
One or more stationary bars or rods b of wire angle or T iron being used to retain
the pins or detectors in their places, and by the application of cams c³, or levers and
of springs c², to other rods c of wire angle or T iron, they are worked vertically to
enable the operator casily to get a detector off the detector bar when a thread is
broken. When flossy material is used, angle or Tiron is used and worked vertically,
and when the machine stops for a piecing up, the angle or T iron c, by the action
of cams c¹, or levers, is taken in such a position as to allow the operator more
easily to get at the detectors and piece the threads. When the material is not
flossy, stationary bars, rods, or wires f, shewn at Fig. 3 are sufficient, and do not
allow a detector to come in contact with the oscillating bar d, and stop the
machine.
I make the pins a of round wire without the twist at the upper end, as is now
customary, so that there can be a greater number of threads in a less space than
heretofore. The angle, or T iron, or gutter iron c is used for the purpose of taking
or pushing floss from the detectors and detector bars; each time the machine stops,
one side of the angle or T iron moves by the action of cams or levers, and passes
down by the side of the detectors a and bars, and pushes the floss off them every
time the machine stops, and keeps them clean so as not to allow the detector to be
held up by accumulated floss. The angle, T, or gutter iron c is moved below the
level of the detector bar or bars, so as to enable the operators to easily get at the
detectors with their fingers.
My improved self stopping motion consists in working from a drum or driving
shaft lovers secured to a shaft in the frame, and at the top of the levers I secure a
wire rod g which comes in contact with the detector when the thread is broken and
stops the machine. There is a connection from the drum or driving shaft h to the
oscillating bar shaft d, by a lever or rod and spring secured to the lover on the
oscillating bar shaft; the spring which is worked in conjunction with the lever d
and oscillating bar shaft d' yields or gives way when a thread is broken or absent,
and allows one end of a jointed lever i, shewn in Fig. 4, to fall, which is held up
when a thread is entire, but when a thread is broken, the one end of the jointed
lever with double catch moves laterally and releases the knocking off spring, and
stops the machine; in the opposite motion of the bar, when a thread is broken, the
end of the jointed catch lever is moved laterally as before described.
In performing my improvements in colored warp beaming for enabling short
lengths of warps to be worked advantageously for coloured material, I dispense
with the old style of warping mill which has no stopping arrangement, and for
warping a greater number of ends or threads with expanding reeds and combs than
has heretofore been done by using expanding and contracting reeds, and variable
width of beams for warps can be used. The front expanding reed dents shewn at

page_text: Figs. 5 and 6, I make out of round wire dents with elongated slots at both ends,
with an eye in the middle of the dents for threads to go through, known as Barlow's
patent wire healds, the lease of the warp is got by this expanding reed at the end
of each warp, or at any part of the warp. The frame o for expanding the wire
healds works in slots in brackets & secured to the front of the machine; a shaft n
with eccentrics or cams n¹, is worked in these brackets under the expanding frame
o; when the machine is working threads run through eyes in the wire healds; when
the lease is to be taken the eccentric or cams n¹ are turned by a handle, the
threads in the eyes of the healds being taken down, and the threads at the sides of
the healds remain in the ordinary position, the lease band being put through
between the ends. The eccentrics or cams n¹ are turned in an opposite direction
when the threads in the eyes are lifted upwards, the threads at the side of the
healds remain in their ordinary position, and the lease bands being put through
between the warp threads.
I make the framing of the front expanding healds of small hinged rods o of iron,
plain or serrated like a saw, and at each end of the wire healds are elongated slots
through which the hinged rods pass. These hinged rods are arranged in the
framing to be worked with right and left handed screws j, and as the small hinged
rods are closed by turning the right and left handed screws, the angles of the rods
become more acute, and the healds and threads occupy less space, and the healds
and threads occupy more space as the angle of the rods is made more obtuse. I
increase the number of hinged rods according to the number of ends required. In
arranging a greater number of ends in little space in the back expanding reed, the
dent ends are made parallel with each other, the other portion of the dent is made
at an angle to the ends, the ends having springs as arranged in the expanding
back reeds commonly used; by this arrangement of dents, several threads can work
between two dents, and the threads are more equally divided, and a good sheet is
obtained. Near the back expanding reed I place a number of glass or iron rods or
rollers between the reed cap and the reed case to divide the threads.
My improved pins or detectors are much simpler than those hitherto made of
round steel wire, and all for the purpose of getting a greater quantity in less space;
any number of detector bars inay be used according to the number of threads
required in the warp. I make my improved pins with a straight bend at the top
instead of twisted; I also use in front of the expanding front heald frame an
expanding comb when required.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim,-
First. Stopping warping machines when the warp threads break in the manner
shown and described.
Second. Removing the floss and dust from the detectors and the detector bars
mechanically, and the manner of performing the same as shewn and described.
Third. The improved detector pins as shewn and described.
In witness whereof, I, the said William Rossetter, have hereunto set my
hand and seal, this Nineteenth day of December, One thousand eight
hundred and seventy nine.
