Improvements in the Shuttle Box Mechanism of Looms for Weaving.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth and Company,
Limited, of Dobcross, in the County of York, Power Loom Makers, do hereby
declare the nature of this invention (which has been communicated to me by
Horace Wyman, of 311, Main Street, Worcester, State of Massachusetts, in the
United States of America, Power Loom Maker), to be as follows:-
This invention in shuttle box mechanism for looms has for its object to provide
suitable means for automatically throwing out of operation the pattern surface
feed and multiplier feed on breakage of a weft or filling thread, or when, for any
reason, it is desired to operate the loom for a considerable period of time with the
same weft or shuttle, as when weaving the body of a blanket or other equivalent
large body of fabric.
My invention is particularly adapted for use in connection with box mechanisms
wherein the pattern surface and multiplier feeds are actuated alternately, as, for
instance, when connected with a common actuator and facing in opposite direc-
tions, so that one feed will operate on movement of the actuator in one direction
the other being operated on the return movement of the actuator.
In mechanisms at present in use where two feeds are alternately operated, if,
when the loom is stopped, one feed be thrown out of action and the other not
thrown out of action, the latter feed, when the loom is again started, will operate
to impart a feeding movement to its mechanism before the first one can pick up
or recover the feed which it lost when the loom was stopped, and therefore the
said latter feed will over run the first feed, and thereby throw the two out of
proper timing one with relation to the other.
To obviate this when either of the feeds is thrown out of action the other
should likewise be thrown out and held out of action until the first has picked up
or recovered the feed which it lost, so that, in the subsequent operation of the
loom, the two feeds may follow each other in proper order as if no breakage had
occurred.
One object of the first part of my invention is to provide an improved mechanism
for automatically throwing out of action both the pattern surface and multiplier
feeds on breakage or slackening of a weft or filling thread and to hold one of the
feeds out of action until the other which first lost a feeding movement shall have
recovered the same.
My invention also comprises suitable improved mechanism actuated from or
controlled by the pattern surface, to automatically throw out of action both the
pattern and multiplier feeds when it is desired to operate the loom with a single
shuttle or weft for a considerable period of time to thereby enable the pattern and
multiplier surfaces to be shortened, the said feeds being again thrown into action

page_text: by some moving part of the loom, as the take up beam, at the end of a predeter-
mined movement of said loom.
The mechanism I employ for the above purpose consists primarily of a dis-
engaging lever arm loosely mounted on the same stud which carries the multiplier
cam and its ratchet wheel. This lever arm is connected by a vertical rod to one
end of a horizontal lever, fulcrummed on the frame of the loom and connected at
its other end by means of a link to the arm of the stop rod of the automatic weft
stop motion. When during the working of the loom, a weft thread breaks or
becomes too slack, the stop rod arm will be raised and thus through the link and
horizontal lever already mentioned the vertical rod will cause the disengaging
lever arm to throw both the pattern surface feed pawl, and the multiplier feed
pawl out of action.
In order to hold the feed pawls disengaged or out of action until such time as
they can be again put into action in the same order in which they were operating
when stopped, which is the object of this part of my invention and which I effect
by mounting in a suitable position on the loom frame, a hanging finger or dog
suitably notched to engage with a pin on the horizontal lever above referred to,
said finger or dog being forced towards the said pin by means of a flat or other
spring. When the horizontal lever is operated by the stop mechanism to throw
the multiplier and pattern feeds out of action, the pin thereon being carried below
the notch on the finger or dog, the spring forcing the lug or dog over the pin
thereby holding the horizontal lever in its new position with the feed pawls out
of action, until it is desired to restart the loom when by suitable mechanism the
lug or dog will be disengaged from the pin to allow the horizontal lever to again
put the feed pawls into action its operation being assisted if necessary by a spring.
The mechanism I employ for releasing the finger or dog for putting the feed
pawls into action when it is desired to restart the loom may consist in forming the
lever which operates the actuator connecting rod with an upwardly extending arm
which as said lever is acted upon by the cam on the cam shaft, will move forward
and strike the finger or dog and move it from engagement with the pin, whereby
the horizontal lever is free to move the feed pawls back into action.
For throwing out of action both the pattern and multiplier feeds for considerable
periods of time when it is desired to weave large bodies of fabric without changing
the shuttles I mount in a suitable position on the loom frame, a lever adapted to
be acted upon by a roll or rolls on the pattern chain. This roll or rolls is or are
introduced into the pattern surface at such a point that when, in the weaving of
the fabric, the body portion thereof is reached, such roll or rolls will pass under
and raise said lever which is connected to a vertical rod provided with a hooked
end. This vertical rod when operated engages a pin on the horizontal lever
previously mentioned, and actuates it to cause it by means of a lever and rod to
throw both the pattern surface and the multiplier feed pawls out of gear with their
respective ratchet wheels the horizontal lever being locked in its new position by
the finger or lug previously referred to until the body of the pattern is woven.
To release the horizontal lever when thus held for purposes mentioned I arrange
by suitable gearing from the take up beam, that when it is desired to release said
lever, that a lug on one of said gear wheels strikes a finger on an arm attached to
the hooked end of the lever engaging the pin on the horizontal lever and leaves
same free to be operated by releasing the dog or finger as previously described to
replace both the feeds into action for weaving the remainder of the fabric.
I wish it to be understood that I do not limit myself to the precise construction
of parts described as it is evident that the same may be varied without departing
from the scope of my invention.

I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth and Company,
Limited, of Dobcross, in the County of York, Power Loom Makers, do hereby
declare the nature of this invention (which has been communicated to me by
Horace Wyman, of 311, Main Street, Worcester, State of Massachusetts, in the
United States of America, Power Loom Maker), and in what manner the same is
to be performed, to be particularly described and ascertained in and by the follow-
ing statement:―
This invention in shuttle box mechanism for looms has for its object to provide
suitable means for automatically throwing out of operation the pattern surface
feed and multiplier feed on breakage of a weft or filling thread, or when, for any
reason, it is desired to operate the loom for a considerable period of time with the
same weft or shuttle, as when weaving the body of a blanket or other equivalent
large body of fabric.
My invention is particularly adapted for use in connection with box mechanisms
wherein the pattern surface and multiplier feeds are actuated alternately, as, for
instance, when connected with a common actuator and facing in opposite direc-
tions, so that one'feed will operate on movement of the actuator in one direction,
the other being operated on the return movement of the actuator.
In mechanisms at present in use, where two feeds are alternately operated, if,
when the loom is stopped, one feed be thrown out of action and the other not
thrown out of action, the latter feed, when the loom is again started, will operate
to impart a feeding movement to its mechanism before the first one can pick up
or recover the feed which it lost when the loom was stopped, and, therefore, the
said latter feed will over-run the first feed, and thereby throw the two out of
proper timing one with relation to the other.
To obviate this when either of the threads is thrown out of action the other
should likewise be thrown out and held out of action until the first has picked up
or recovered the feed which it lost in order that, in the subsequent operation of the
loom, the two threads may follow each other in proper order as if no breakage had
occurred.
One object of the first part of my invention is to provide an improved mechanism
for automatically throwing out of action both the pattern surface and multiplier
feeds on breakage or slackening of a weft or filling thread and to hold one of the
feeds out of action until the other which first lost a feeding movement shall havo
recovered the same.
My invention also comprises suitable improved mechanism actuated from or
controlled by the pattern surface, to automatically throw out of action both the
pattern and multiplier feeds when it is desired to operate the loom with a single
shuttle or weft for a considerable period of time, to thereby enable the pattern and
multiplier surfaces to be shortened, the said feeds being again thrown into action
by some moving part of the loom, as the take-up beam at the end of a predeter-
mined movement of said loom.
The drawing, Fig. 1, in vertical section and partial elevation. shows a sufficient
portion of a loom embodying my invention to enable the latter to be understood;
and
Fig. 2, an enlarged detail showing a back view of some of the parts in different
positions.
Referring to the drawings, the frame A; breast beam C; cam or low shaft D;
weft fork 40 and its slide: the hooked finger 6; the stop red 5, its arm 4; pattern

page_text: chain or surface e6; the shaft i8 on which the pattern surface is mounted;
ratchet 2, with its feed pawl f 6, which in the present instance constitutes the
feeding device for the pattern surface; the multiplier cam or surface 10, its
ratchet 13, mounted on a stud 14, and actuated by the pawl 18, which, in this case,
constitutes the multiplier feed device and with the pattern-surface-feed pawl f 6
are secured to and alternately moved to operate their respective feed mechanisms
or surfaces by the common actuator B; and the pawl lifters 7 and 19 are and may
be of suitable construction, and since the construction and operation of this type
of box mechanism is well understood by those conversant with the art, it is con-
sidered unnecessary to enter into a more detailed description of same; except to
state generally that the movable lifter 19 is, in the mechanisma shown, controlled
by the pattern chain or surface e 6, which also controls the box mechanism; and
the pattern feed lifter 7 is controlled by the multiplier surface 10; the pattern and
multiplier feeds being arranged to operate in opposite directions and alternately
by the vibrations of the actuator B, the latter being actuated by the rod g6 con-
nected to a lever G, held in contact with a cam 6 on the cam shaft. by a suitable
spring, as c 7.
According to my invention, (see Fig. 2,) I have loosely mounted upon the stud 14,
carrying the multiplier-pattern-surface 10, a disengaging lever arm m, of such
shape and construction, that when moved from its full line position, Fig. 2, it
will act to lift or separate the multiplier feed pawl 18 and lower the pattern-feed-
lifter 7 in order to move the upper one from possible engagement with the teeth
of its ratchet 13, and to lift the pattern-feed pawl f6 from engagement with the
teeth of its ratchet 2.
This disengaging lever m is shown as provided with a radially extended arm
connected at its lower end by a vertical rod m¹ with a lever m2, (see Fig. 1.)
pivotted on the frame at m 3 and connected at the opposite end of said lever by
a link m 4 with the arm 4 of the stop-rod 5 of the automatic weft stop motion for
the loom.
When, during the operation of the loom, the weft-slide carrying the weft-fork 40
is moved to the right, Fig. 1, to stop the loom in well known manner because of
the breakage or undue slackening of a weft thread, the hooked finger 6 will be
moved to rotate the stop rod 5 and raise its arm 4 to thereby operate through the
link m 4 the lever m2 and rod m¹ to depress the arm referred to on the disengaging
device m and turn the latter in the direction of the arrow, Fig. 2 to throw out of
action both feed devices in the manner described.
I have herein provided suitable means to hold the feed devices disengaged or
out of action until such time as they can be again put into action in the same order
in which they were operating when stopped, such means being herein shown in
the form of a holding device, as a dog n, pivotted to the frame at n¹, and notched
at n 2 to co-operate with a pin n 3 on the lever m 2, referred to, a spring 4 acting
to press said dog towards the pin.
When the lever m 2 is moved, as described, to throw out of action the multiplier
and pattern feeds, the pin 3 is carried below the notch n 2 permitting the
spring n 4 to move the dog over the pin to hold the lever m 2 in its new position
with the feed devices out of action, the parts remaining thus held out of action
until the proper time, usually the second pick after that at which the loom was
stopped, when, in suitable manner, the dog n will be disengaged to permit the
lever m 2 under the action of its spring m 5 to move to again introduce the feed
devices into action.
In the present embodiment of my invention for the release of the dog n, referred
to, I have provided the lever 6 with an upwardly extended arm h6, which, as
the cam 6 drops said lever, will engage the dog n and move it to release the
lever m2, as described, and, at this time. if the lever 6 and weft fork stick have
been restored to their normal position for the usual operation of the loom the
lever m2 will, by means of spring m 5, assume its normal position.
For throwing out of action both the pattern and multiplier feeds for considerable

page_text: periods of time when it is desired to weave large bodies of fabric without change
of shuttles I have herein provided a lever o, see Fig. 2, fulcrummed upon the
frame at o' and adapted to be raised at the proper time by a roller or rollers o 2.
or other suitable change, in or on the pattern-surface e 6, said lever being shown
as provided with a depending rod o 3, carrying at its lower end a notched or
hooked head o 4 adapted to lie normally beneath a pin o 5 on the lever m 2, referred
to.
The roller o2 is introduced into the pattern surface at such point that when in
the weaving of the fabric the body portion is reached it will pass under and lift the
lever o and thereby through its hooked head o4 and the pin o 5 turn the lever m2
into its position described for throwing out of action both the multiplier and
pattern feeds, said lever being at once locked in this new position by the dog n,
referred to.
To release the lever m 2 when thus held by the hooked head o4 at the proper
time I have connected with said head a bar o 6 adapted to rest upon and be held
in contact with a cylindrical shoulder p on and rotatable with a toothed wheel p1,
see Fig. 1, a spring p3 being preferably employed to hold the bar o 6 in operative
contact with the said shoulder.
The wheel p is connected through suitable gearing or otherwise with a gear på
in and rotatable with the take up roller or shaft p, said wheel p₁ being also pro-
vided, preferably adjustably, with a finger p 5 adapted to engage a roller or other
stud 6 on the bar o 6 so that at the proper time in the rotation of the wheel m¹,
which time is determined by the gearing between it and the take-up roller, the
said finger p5 will engage the stud p6 and move the bar o 6 and the hooked
head o4 to the right, Fig. 1, to release the pin o5 and the lever m2 and permit
the latter, immediately thereafter, to be released, as heretofore described, by the
lever 6 to throw into action both feeds for the finishing of the fabric.
My invention is not to be limited to the particular embodiment or construction
herein shown, for it is evident that the same may be varied without departing
from the spirit and scope of my invention.
