Improvements in or relating to Beam Warping Frames.
1, HENRY BRERETON of Hill Bank House, Halliwell, Bolton in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be as
follows:
This invention refers to improvements in or relating to beam warping frames
employed for preparing yarn for weaving and is designed to reduce friction on the
yarn, prevent jerking, dancing, and the stopping pins dropping into pin box when
the frame stops or the yarn becomes slack, and in means for instantly stopping the
frame when an end or ends break, by which the same may be readily found without
operating the yarn beam; and for arresting and maintaining the position of the
falling or dancing rollers employed for taking up slack yarn when creeling or
taking a beam out of the frame, the latter dispensing with the old or present
system of tieing up the same with string and the like. The pin frame is fitted
with metallic wires, bars, or their equivalents, or with bars or bearing surfaces of
glass, earthenware, or other suitable material or substance, suitably mounted in
bearings at each end of the frame, or the middle bars of the pin frame may be
provided with semi-circular or other raised surfaces, over which the yarn passes
and between which the stopping pins are suspended on the yarn in its passage from
the creel to the beam. The wires, bars, or bearing surfaces may be of any of the
before mentioned materials or substances, bedded on or in the upper side of the
pin frame. By this arrangement of the wires, bars, or elevations the pins and
yarn are supported in close position to each other, thereby minimising jerking and
dancing and the swaying of the yarn, and also prevents the pins dropping with the
yarn between the ordinary stopping rollers when the beaming frame is stopped, or
when the yarn becomes slack, thereby keeping the pins steady when working and
reducing friction on the yarn considerably. For the purpose of instantly stopping
the machine and to prevent the yarn beam making a revolution, the driving shaft
is fitted with a brake pulley round or over which is disposed a brake band or
belt; one end of the latter being secured to a fixing mounted on the floor, and the
other end to a lever on the stopping or other shaft. The brake band or belt is
provided with means for adjustment to compensate for the necessary tension. In
case it is necessary to rotate the yarn beam by hand after the frame has been
stopped, it is effected by pressing down the foot-rod or lever gently by which the
brake band or belt is liberated or released from the brake pulley. If desired the
driving pulley may be constructed and fitted with a cone, which is pressed into
gear by a tapered disc mounted on a centre attached to a lever on the stopping or
other shaft. Immediately the frame is thrown out of gear, either automatically
by the pins, or by hand, the aforesaid lever operates a compound lever pivoted to.
the framework and presses one end covered with leather or its equivalent against
the face of the driving pulley and stops the frame. For maintaining the working
position of the falling or dancing rollers when the machine is stopped for creeling
or the removal of a full or other beam, the framework is fitted at each end with a
slide carrying slots or projections, which are slid automatically under the bearings
of the said rollers by means of levers operated by rods from an adjustable lever or
levers attached to the stopping or other shaft ; and which are re-set immediately
the brake band or belt is released from the brake pulley to set the frame in

page_text: motion. The said slides may be locked by slides or their equivalents loosely
mounted on the framework of the frame.

I HENRY BRERETON of Hill Bank House, Halliwell, Bolton, in the County
of Lancaster, Manager, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement and accompanying drawings:-
This invention refers to improvements in or relating to beam warping frames
employed for. coiling yarn upon the warp beams of looms for weaving and is
designed to reduce friction on the yarn, prevent jerking, dancing, and the stopping
pins from dropping into the pin box when the frame stops or the yarn becomes
slack. The invention also refers to means for instantly stopping the frame when
an end or ends break thereby permitting the broken ends to be readily found
without operating the yarn beam; and for arresting and maintaining the position
of the falling or dancing rollers employed for taking up slack yarn when creeling
or taking a beam out of the frame, the latter dispensing with the old or present
system of tieing up the same with string and the like. The pin frame is fitted
with metallic wires, bars, or their equivalents, or with bars or bearing surfaces of
glass, earthenware or other suitable material or substance, suitably mounted in
bearings at each end of the frame, or the middle bars of the pin frame may be
provided with semi-circular or other raised surfaces over which the yarn passes and
between which the stopping pins are suspended on the yarn in its passage from the
creel to the beam. The wires, bars or bearing surfaces may be of any of the
before mentioned materials or substances bedded on or in the upper side of the pin
frame. By this arrangement of the wires, bars or elevations the pins and yarn
are supported in close position to each other, thereby minimising jerking and
dancing and the swaying of the yarn and also prevents the pins dropping with the
yarn between the ordinary stopping rollers when the beaming frame is stopped
or when the yarn becomes slack thereby keeping the pins steady when working
and reducing friction on the yarn considerably. For the purpose of instantly
stopping the machine and to prevent the yarn beam making a revolution, the
driving shaft is fitted with a brake pulley round or over which is disposed a brake
band or belt, one end of the latter being secured to a fixing mounted on the floor,
and other end to a lever on the stopping or other shaft. The brake band or belt
is provided with means for adjustment to compensate for the necessary tension.
In case it is necessary to rotate the yarn beam by hand after the frame has been
stopped it is effected by pressing down the foot rod or lever gently by which the
brake band or belt is liberated or released from the brake pulley. If desired the
driving pulley may be constructed and fitted with a cone which is pressed into gear
by a tapered disc mounted on a centre attached to a lever on the stopping or other
shaft. Immediately the frame is thrown out of gear either automatically by the
pins or by hand the aforesaid lever operates a compound lever pivotted to the
framework and presses one end covered with leather or its equivalent against
the face of the driving pulley and stops the frame. For maintaining the working
position of the falling or dancing rollers when the machine is stopped for creeling
or the removal of a full or other beam the framework is fitted at each end with a
slide carrying slots or projections which are slid automatically under the bearings
of the said rollers by means of levers operated by rods from an adjustable lever or

page_text: levers attached to the stopping or other shaft and which are re-set immediately the
brake band or belt is released from the brake pulley to set the frame in motion.
The said slides may be locked by slides or their equivalents loosely mounted on the
framework of the frame.
To render my invention more clearly understood I will now proceed to describe
the same particularly and with reference to the annexed sheet of illustrative
drawings.
Fig. 1 is a cross sectional view of the ordinary pin box or pin bar to which my
improved yarn supporting wires are shown applied. The ordinary stopping rollers
are indicated beneath the said pin bar. Fig. 2 is a side view of a portion of
the bar.
Fig. 3 is an end view of the warp beam driving roller to the axis of which my
improved stopping brake is shown applied.
Fig. 4 is a plan of Fig. 3.
Figs. 5, 6, 7 and 8 illustrate my improved means for mechanically supporting
the dancing rollers when the machine is stopped for creeling or for removing the
warp beam.
Referring first to the improvement which relates to the pin box and to Figs. 1
and 2 of the drawings, the pin bar a is of the ordinary description with slots a¹
through which the staple shaped pins hang pendent from the passing yarn c.
Under former practice the yarn in passing over the pin bar a and through the
pins had no support and consequently ran very unsteadily, shaking and jerking,
and sometimes when the yarn became slack allowing the pins to drop so far
through the bar a that they occasionally got between the stopping rollers ¹ and
stopped the machine besides breaking the yarn.
To obviate these disadvantages I provide supports to carry and steady the yarn
in its passage over the pin bar. In the arrangement chosen for illustration these
supports consist of small rods or wires d which extend or are stretched along the
top of the pin bar a between supports e. These supports can be screwed into
existing pin bars so that there is no difficulty in applying my invention to machines
at present at work.
Jamb nuts d' secure the wires to the supports e and permit of adjustment in
the slots e¹. I do not however confine myself to the illustrated rods or wires d as it
will be evident that supports equally efficient might be constituted from bearing
surfaces of glass, earthenware or metal supported above or fitted into or formed on
the bar a. By the use of such supports, the yarn is prevented from being subject
to the usual shaking, jerking and swaying motions and is enabled to support the
pins at a steady level, thereby reducing friction or lessening the danger of
breakage of the yarn.
The next part of my invention is illustrated by Figs. 3 and 4 of the drawings.
In the said figs. the roller is the usual roller which drives the warp beam g by
frictional contact. When the frame is knocked off in the usual manner on the
breakage of an end, the roller f and warp beam g are not immediately arrested but
perform one or two revolutions so as to wind on the broken end and render its
recovery for piecing up difficult, without turning the warp beam back. According
to my invention I apply a brake to the shaft of the roller. A brake pulley
is mounted upon the shaft f¹. A brake strap i is passed partly around this brake
pulley one end being secured to a fixed support and the other end adjustably
connected to a lever k fixed upon the existing starting and stopping shaft 1. The
shaft exists in present machines and is operated by a weighted lever m and
treadle n (shown in dotted lines) the latter being depressed by the foot of the
attendant when it is desired to start the machine.
When a yarn end breaks and the corresponding pin by falling between the
rollers moves the roller forward and knocks off and stops the machine in
the ordinary manner, the weighted lever m falls into the position indicated in
dotted lines in Fig. 3 and throws forward the upper end of the lever k so as to
draw the strap i firmly down upon the pulley and thus arrest at once the rotation of

page_text: the roller and consequently of the warp beam. When the attendant depresses
the treadle n in re-starting the machine the brake strap slacks back and exercises
no retarding influence. The finger o and rod p which appear in Figs. 3 and 4 will
receive mention in describing the remaining part of my invention.
This remaining part refers to the means for giving support to the so called
dancing rollers used in these machines to take up the slack of the yarn and keep it
at an even tension. When the warp beam has been filled or when from any other
reason it is necessary to remove it from the machine it is customary first of all to
tie up the said dancing rollers with string or any rude means at hand. Under my
invention provide mechanical means for supporting the rollers and these means
are illustrated in Figs. 5 to 8 of the drawings.
I mount brackets q upon the top of each end frame the said brackets having
hangers which fit spindle necks projecting from the ends of the dancing
rollers. The dancing rollers are indicated by the dotted circles surrounding the
necks r. A bell crank lever s is pivotted upon a bracket t on the top of the end
frame u. One slotted arm of this bell crank levers engages with a stud u¹
projecting from the bracket q and as the bracket 7 is free to slide to and fro it will
be seen that by moving the bell crank levers the bracket 7 can be slid either
backward so as to move the hangers q clear of the necks as in Fig. 5; or forward
so as to embrace and support the necks as in Fig. 6. As the position of the parts
in Fig. 5 (ie. with the hangers q' clear of the necks r) is the normal position
I make provision for locking the brackets q in this normal position. To this end
I provide a sliding stop v carried on the side of the bracket t. When the stop is
down, as for example in Fig. 5 the stop lies against the portion of the sliding
bracket q which is cut out to avoid the brackett (see Fig. 8) and thus locks the
bracket in this position. When it is desired to slide the bracket q forward so
as to support the dancing rollers I lift the stop and depress the upper arm
of the bell-crank lever s so as to push the bracket 9 forward into the position
shown in Fig. 6. The sliding bracket q is retained on the top of the frame by
studs w which pass through slots in the flange of the bracket and are screwed into
the top of the frame. Both ends of the machine are fitted with these brackets g
and operating bell crank levers so as to support both ends of the dancing rollers.
I also make provision whereby the sliding brackets q are moved back simultaneously
with the starting or re-starting of the machine, this provision being introduced to
prevent the machine from being run while the dancing rollers are still supported
by the brackets q. I have already shown in Figs. 3 and 4 that the stopping and
starting shaft carries a finger o. A stud o from this finger passes through a slot
in the foot of a rod p which rod should be made adjustable as to its length. The
rod p extends upwards and is adjustably connected to the upper slotted arm of the
bell crank levers as clearly appears in Figs. 5 and 6. When the bell crank
levers is in the position shown in Fig. 5 the slotted foot of the rod p is about in
the position shown in Fig. 3, that is to say the bulk of the slot is above the
stud o¹.
Therefore the bell crank levers s may be depressed and the brackets
advanced
without affecting the finger o or stopping or starting shaft l, the only résult being
that the top of the slot in the foot of the rod p is brought down upon the stud o¹.
But when the treadle n is operated in starting the machine, the finger rises,
pushing up the rods p and throwing the bell crank levers s from the position shown
in Fig. 6 into the position shown in Fig. 5 thus releasing the dancing rollers from
the hangers q'. At the same time the stop drop and automatically lock the
brackets 7 in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In beam warping frames and in combination with the pin bars and pins used
therein the employment of sunnorts such for example as the rods or wires d or

page_text: their equivalents for sustaining and steadying the yarn as it passes over the pin
bar, substantially as described and shown in Figs. 1 and 2 of the drawings.
2. In beam warping apparatus the improved brake connected with the starting.
and stopping shaft or bar and arranged to arrest quickly and automatically the
motion of the frame when the machine is knocked off or stopped by the breaking
of a yarn end or from other causes, substantially as hereinbefore described and as
illustrated in Figs. 3 and 4 of the drawings.
3. The improved arrangement for mechanically supporting the dancing rollers
of beam warping machines by means of the sliding brackets q with hangers q'
arranged and operating substantially as described and as illustrated in Figs. 5 to 8
of the drawings.
4. The means for automatically disengaging the brackets and hangers q q¹ from.
the axes of the dancing rollers, simultaneously with the starting of the machine,.
substantially as described and as illustrated.
