Improvements in Actuating Shuttle Boxes in Looms for Weaving,
and also in Jacquard Harness.
I, EDWARD HOLLINGWORTH, of the Firm of Hutchinson, Hollingworth and Company,
Limited Dobcross Iron Works, Dobcross, in the County of Lancaster, Loom Makers
do hereby declare the nature of this invention to be as follows:-
The first part of my invention has reference to a new or improved form and
construction of mechanism for selecting and operating the shuttle boxes in looms for
weaving, being specially adapted for weaving stripes, checks, and the like.
In carrying out my invention I use preferably at the head of the loom what is
commonly known as a barrel motion, the periphery of which is perforated with holes
arranged spirally, into which holes, pegs or studs are inserted varying according to
the selection of the shuttle boxes and the pattern desired to be woven. This
perforated barrel is made to revolve intermittently the distance of one hole to another
by an arrangement of star and peg wheels. On one end of the barrel shaft is a spur
wheel in gear with a pinion wheel on the end of a screwed shaft, the screw of such
shaft corresponding to the spirally arranged holes in the barrel. This screwed shaft
operates and causes a curved back lever nut to travel forward on the said screwed
shaft carrying with it a pegging lever which whilst it can rock its shaft is yet capable
of sliding thereon by means of a key and groove. The opposite end of the said
screwed nut causes another finger to fall on a rocking shaft also provided with a key
and groove, therefore when a stud in the barrel comes into contact with the forward
end of the pegging lever it actuates a vertical rod in gear with a clutch lifting a peg
into or out of a notch in a star wheel and when a peg is absent from the barrel the
pegging lever drops whereby the action of the clutch is reversed.
When the barrel is to be reversed a longer peg or stud than those for operating the
above named clutches is employed, such peg striking a lever on the lower end of the
screwed nut, the action of which causes another lever having a pin in a horizontal
slotted lever to lift the said slotted lever, the action of which causes a clutch to be
lowered thus removing a cam from contact with a bowl on another horizontal slotted
lever, such said can coming into contact with another bowl on the said horizontal
slotted lever, the action of which causes the said horizontal lever to slide and through
the medium of a bell crank lever another clutch is operated, and through the
intervention of another peg and star wheel, the barrel is revolved in an opposite
direction.
By the employment of the lever motion together with the various arrangements of
clutches and star wheels herein referred to, a very reliable shuttle box motion is
constructed positive in its action and easy to manipulate, and will give a large or
wide arrangement of latitude for weaving stripes and checks in great variety.
The second part of my invention refers to harness looms, the object of my invention
being to provide a handy and realy means for reversing the motion of the parts of the
jacquard. To do this I hinge near the head of the loom a short lever with a toe piece
at one end, the other end of said lever being connected by cord or wire to a needle of

page_text: the jacquard. I also provide another lever with a toe piece, which is so shaped as to
come into contact with the said toe piece on the first lever. This second lever is
weighted and at the opposite end to the toe piece it is also connected to another
needle hook of the jacquard by cord or wire, and also to the catches which turn over
the jacquard card cylinder. When the first lever is operated it allows the second to
fall, thereby allowing the card cylinder to turn in one direction. When the second
weighted lever is operated by the needle of the jacquard it brings (by reason of the
said toe piece) the first lever again into position and also operates the catches of
jacquard by means of the said cord or wire which is connected up to the catches,
thereby causing the card cylinder to revolve in the opposite direction.
By the use of these levers the action of the jacquard card cylinder can be readily
reversed automatically by the loom during the process of weaving,

Improvements in Actuating Shuttle Boxes in Looms for Weaving,
and also in Jacquard Harness.
1, EDWARD HOLLINGWORTH, of the Firm of Hutchinson, Hollingworth and Company,
Limited, Dobcross Iron Works, Dobcross, in the County of Lancaster, Loom Makers,
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:-
The first part of my invention has reference to a new or improved form and
construction of mechanism for selecting and operating the shuttle boxes in looms for
weaving, being specially adapted for weaving stripes, checks and the like.
Such being the nature and object of my invention I will now proceed to explain
the same more fully, aided by the accompanying sheets of drawings, wherein Fig. 1 is
a side elevation of usy improved mechanism and Fig. 2 is a front elevation of same,
3 and 4 being details of some of the parts.
The barrel motion may be placed on the floor of the weaving shed or at the head of
the loom, or below the shuttle boxes, or in any other convenient position but in any
case the barrel motion is used in connection with the jacquard cylinder for controlling
the shuttle boxes and it is more particularly applicable to the Hollingworth and
Knowles Loom.
For the sake of clearness I have omitted the loom framing, as well as the framing
of the jacquard, but 1 represents the top reversing shaft of the jacquard and it has
a continuous rotary motion imparted to it, which by hevel wheels 2 imparts rotary
motion to the vertical shaft 3. Mounted on this upright shaft 3 are two clutches 4 and 5
both of which, by means of a key, are not only capable of being revolved with the
shaft, but can also slide up and down thereon when operated by their respective clutch
forks 6 and 7. Number 8 represents the pegging barrel which is perforated with
holes, arranged spirally, into which holes pegs or studs 9 are inserted varying
according to the selection of the shuttle boxes and to the pattern desired to be woven.
This perforated barrel is made to revolve intermittently the distance of one stud to
another by means of the star wheel 10 which is caused to move from one notch to

page_text: If
another by means of a stud 11 attached to a crank 12 secured to the upright shaft 3,
consequently, at every revolution of the said shaft, the stud 11 rotates the star wheel
the distance of one notch to the next succeeding notch. At the back of the star
wheel 10 is a pinion 13 gearing with a spur wheel 14 on the end of the barrel shaft
whereby intermittent rotary motion is cominunicated to the said barrel and this goes
on continuously until the motion of the barrel is required to be reversed. Number 15
represents a serewed shaft the threads of which are chased to correspond
proportionately with the spirally arranged holes in the barrel 8. This screwed shaft
receives interinittent rotary motion from pinion 16 gearing with and driven from
the spur wheel 14 on the end of the barrel shaft. Mounted upon this screwed shaft is
a nut 17 having two curved arms 18 and 19 which nut 17 traverses on the screw as
the latter revolves. The upper arm 18 of the screwed nut engages with a pegging
lever 20 which whilst it can rock its shaft 21 is yet capable of sliding thereon by
means of a key and groove. The lower aru 19 of the said screwed nut engages with
a bifurcated lever 22 on another rocking shaft 23 which, as in the preceding case, is
made with a key and groove for permitting the finger to slide upon the said shaft.
The pegging lever 20 either rests upon the periphery of the spiral drum or barrel 8
or if pegs 9 are present in the drum, the pegging lever will be raised thereby.
therefore, a stud 9 is in the barrel and comes under the forward end of the pegging
lever 20 said lever is raised and rocks its shaft 21 (see Fig. 3) operating a lever 24
connected by vertical rod 25 to clutch fork 6 whereby the clutch 4 is raised upon the
vertical shaft 3 and places a stud 26 on the crank 27 into a notch in the star wheel 28
and thus imparts rotary motion in one direction to the spur wheel 29 which spur
wheel gears with another spur wheel 30 fixed on the end of the jacquard cylinder
shaft. A thereby imparting motion to the said jacquard cylinder which in turn
operates the ordinary vibrating levers, not shewn, but common to and well known in
the Hollingworth and Knowles Loom. If, however, a peg 9 is absent in the spiral
barrel, the pegging lever 20 will drop, causing the upper clutch 4 to lower and
remove stud 26 from a notch in the star wheel 28 permitting the upper stud 26' to
descend and enter a notch in the said star wheel, and this would cause the rotary
motion of the star wheel to be reversed thus reversing the motion of the jacquard
cylinder. When the rotary motion of the barrel itself has to be reversed (which is
required according to the pattern being woven and for repetition purposes) a longer
peg or stud 31 than those for operating the above named clutch is employed (see
Figs. 1 and 3) such peg being purposely arranged to strike one of the arms of lever 22
on the lower rocking shaft 23 the action of which causes the lever arm 32 to be
actuated. The lower end of this lever carries a stud or pin 33 which enters into the
slot 34 formed in the arm of the clutch fork 35 fulcrummed at 36 said clutch fork
engaging with a clutch 36¹.
It will be observed that on the upper part of the clutch 56' there is a cam 37 which,
as the vertical shaft 3 rotates, is adapted according to its position on said shaft to
come into contact either with the bowl 38 or bowl 41 fastened on studs secured to the
horizontal sliding lever 39. When the barrel 8 is revolving in the direction of the
arrows, the cam 37 is in the position shewn in Fig. 1 and nets against the bowl 38
causing the bell crank lever 40 to actuate the clutch 5 upon the shaft 3 as already
explained, rotating the star wheel 10, but when the rotary motion of the barrel is to
be reversed the peg 31, which determines reversal, abuts against the arm of lever 22
which lies in its path, thus rocking said lever and therefore the shaft 23 and lever 32,
whereby the clutch fork 35 is oscillated on its fulcrum and draws down the clutch 361
which places the can 37 in the plane of bowl 41 upon which it immediately acts and
causes the slotted lever to be slided in the direction of the arrow whereby the bell
crank lever 40 and clutch are operated in such a manner as to raise the said clutch
and place the lower stud 42, connected to the clutch sleeve, into engagement with the
star wheel 10, by which means the rotary motion thereof is reversed and through
the medium of pinion 13 the motion of the barrel 8 is also reversed.
By the employment of the barrel motion together with the various arrangements of
clutches and star wheels herein referred to for controlling the rotary motion of the

page_text: jacquard shaft. A a very reliable shuttle box motion is constructed, positive in its
action and easy to manipulate, giving a large and wide arrangement of latitude for
weaving stripes and checks in great variety.
The second part of my invention refers to harness looms, the object of my invention
being to provide a handy and ready means for reversing the motion of the parts of
the jacquard. To do this I hinge on the loom rail or other convenient position a
short lever with a toe piece at one end, the other end of said lever being connected
by cord or wire to a needle of the jacquard. I also provide another lever with a toe
piece, which is so shaped as to come into contact with the said toe piece on the first
lever. This second lever is weighted and at the opposite end to the toe piece it is
also connected to another needle hook of the jacquard by cord or wire, and also to the
catches which turn over the jacquard card cylinder. When the first lever is operated
it allows the second to fall, thereby allowing the card cylinder to turn in one
direction. When the second weighted lever is operated by the needle of the jacquard it
brings (by reason of the said toe piece) the first lever again into position and also operates
the catches of the jacquard by means of the said cont or wire which is connected up
to the catches, thereby causing the card cylinder to revolve in the opposite direction.
Fig. 5 illustrates this part of my invention where A is the jacquard cylinder, B the
catchies connected together by rod C and employed to turn said cylinder in one or
other direction as required.
According to my invention I hinge to the loom rail Da short lever E provided
with a knuckle or toe piece, the opposite end of said lever being connected by cord
or wire F to a needle G of the jacquard and 1 also employ another lever H with a
knuckle or toe piece. This second lever is weighted at I and it is also connected by
wire J to a needle K of the jacquard, and also by another wire L to one of the
catches B. When the lever E is lifted by cord F and needle G the lever His
allowed to fall (as shewn in dotted lines) through its heing weighted, causing the
lower catch B to occupy a position to turn the jacquard cylinder A in one direction.
When cord J is lifted by the needle K it raises lever H into the position shewn in
full line also slackening the cord L which allows lower catch B to fall out of contact
with the cylinder and at the same time draws down the upper catch into contact
with the said cylinder consequently the motion of the cylinder is reversed.
By the use of these levers the action of the jacquard cylinder can be readily
reversed automatically during the process of weaving or the reversal may be effected
by band by the weaver.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
Firstly. In looms for weaving, the controlling of the jacquard cylinder, by means
of a barrel motion, through the medium of the arrangement of clutches 5 and 6 and
star wheels 10 and 28 substantially as described and shewn for operating shuttle
boxes in looms.
