Improvements in Looms.
I, ARTHUR SOWDEN, of Spring Field House, Baildon in the County of York,
Loom Maker, do hereby declare the nature of this invention to be as follows:-
Firstly. This invention relates to improved apparatus for changing the position
of the pattern barrel the object being to bring another series or line of holes of
the latter under the needles, the pattern barrel have additional lines or holes for
this purpose.
I mount on a stud fixed into the framework of the dobby a disc peg wheel or peg
pulley at the back of which and fast thereto is a rachet wheel operated by a catch
worked by a pusher rod. Carried on a cross shaft is a rocking arm the lower part
of which is provided with a slot through which the axis of the cylinder or peg barrel
is received.
The cylinder is carried in slots of two arms as ordinary but such slots are
elongated for purpose hereinafter described.
The action is as follows:-
As the dobby is worked as ordinary the pusher rod above referred to pushes the
catch wheel and peg disc or peg pulley and so long as there is not any peg in the
disc or pulley the cylinder will have its ordinary motion only, but when a peg
occurs the latter will act on the rocking arm and the slotted end will carry the
cylinder forward a distance so as to bring another line of holes under the needles in
which position it will be retained so long as the pegs indicate for that position of
the cylinder but soon as blank occurs the rocking arm will be returned to its
original position through the action of a return spring.
The opposite end of the axis of the cylinder is carried in a slotted pendant arm.
The peg disc or pulley may in lieu of pegs be covered with a pattern chain
which will operate the rocking arm and barrel as described.
Secondly. To improved means of operating the dobby.
Instead of the Trocking arms I employ a series of spaced wheels operated by
bevel gear from an upright shaft. The spaces in the wheels give a dwell so that
the one knife shall in all cases get hold of its hook or hooks before the other knife
releases its hooks, and so the partial dropping of jack levers is prevented. In con-
nection with the upright shaft and bevel gear is a cross shaft, bevel gear and hand
wheel, by means of which the dobby can be turned by hand either direction that is
backwards or forward without moving other parts of the loom. There is a clutch
box on the upright shaft for throwing the parts out of
gear.
Where a rocking arm is employed for operating the draw knives and catches I
mount on the cross shaft of the said arm two tappets which alternately act on
pendant arms connected with the link of the draw bars so that the one tappet
moves out its draw bar and retains it until when a change is to be effected, the
other knife has secured a hold on the catch or catches to be drawn, and thereby
there is avoided that partial dropping of the jacks common to dobbies as heretofore
constructed and operated. A return spring acts on the tappet pendant arms so as
to keep the latter up to the tappets.
Thirdly. To improved apparatus for operating the change shuttle box motion
comprises a cross shaft at the back of the loom on which shaft are spaced gear
wheels driving and locking a lower shaft by a spaced wheel. On the lower shaft is
another spaced wheel gearing with two other spaced wheels one above the other
below the upper and lower spaced wheels have each two series of teeth side by side
and each having locking devices which hold the wheel to the position it has been
moved or set to. The side movement of these wheels is effected through the agency

page_text: of a sliding bar there being one of such bars to each of the upper and lower wheels.
The slides are operated by means of one arm of a bell crank lever there being one
of such levers to each wheel and the said levers are controlled by the pattern
or peg mechanism acting on the upper arm of the lever. On the axis of the shafts
of the upper and lower spaced wheels is a strap eccentric a rod from which extends
downwards and the lower ends are attached to the opposite ends of a swivel piece
working on a stud affixed in the main or ordinary box lever at the lower part of
the loom. When five or more boxes are to be employed in addition to the ordinary
main lever there is a compound lever and additional spaced wheels and bell cranks
operated as described.
The clutch box and upright shaft already referred to in connection with the
dobby serves to throw out the shuttle changing mechanism so that the loom can be
reversed without moving the boxes, or the boxes can be moved without other parts
of the loom.
The mechanism it will be understood is applied to both ends of the loom for the
two series of boxes.
I drive the loom by friction discs thrown in and out by a side shaft one end of
which is connected by an arm to the stop handle lever the other end of the said
shaft carries an arm or crank communicating with a boss on the friction motion or
main shaft.
The arrangement above described affords considerable leverage or power over
the friction motion.
Where the shuttle boxes are to be operated direct from the dobby I employ a
chain, cord, or racks passed over a pulley mounted on the upper arm of a bell
crank or straight lever having a fulcrum about midway its length the lower arm of
the lever is connected to the end of a rod extending across the front of the loom
and near the top rail.
To the outer end of the rod is attached to a bell crank lever and the latter by
connecting rod is attached to the box or main lever for operating the shuttle boxes.
So long as the knife of the dobby is engaged with the draw hook the particular box
brought in line with the shuttle race will be steadily held in that position until a
changed is indicated.
It will be understood that the number of hooks, levers, cranks and rods as
described are in accordance with the number of cells or shuttle boxes of the looms.
The main or shuttle box lever is a broken back or escapement lever consisting of
two lengths jointed or hinged together the joint being secured in its working
position under ordinary conditions by two springs which give way when any undue
or extra strain is put upon the lever, and thus prevent breakage.

COMPLETE SPECIFICATION.
Improvements in Looms.
I, ARTHUR SOWDEN of Spring Field House, Baildon in the County of York
Loom Maker, 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 :-
Firstly. This invention relates to improved apparatus for changing the position
of the pattern barrel, the object being to bring another series or line of holes of
the latter under the needles, the pattern barrel having additional lines of holes for
this purpose.
I mount on a stud fixed into the framework of the dobby a disc peg wheel or
peg pulley at the back of which and fast thereto is a ratchet wheel operated by a
catch worked by a pusher rod. Carried on a cross shaft is a rocking arm the

page_text: lower part of which is provided with a slot through which the axis of the cylinder
or peg barrel is received.
Each end of the cylinder is carried in slots of two arms as ordinary but such slots
are elongated to allow of movement of the said cylinder.
The peg disc or pulley may in lieu of pegs be covered with a pattern chain which
will operate the rocking arm and barrel as described.
Secondly. To improved means of operating the dobby. Instead of the T rocking
arms I employ a series of spaced wheels operated by bevel gear from an upright
shaft. The spaces in the wheels give a dwell so that the one knife shall in all
cases get hold of its hook or hooks before the other knife releases its hooks, and so
the partial dropping of the jack levers is prevented. In connection with the
upright shaft and bevel gear is a cross shaft, bevel gear and hand wheel by means
of which the dobby can be turned by hand in either direction that is backwards or
forwards without moving other parts of the loom.
There is a clutch box on the upright shaft for throwing the parts out of gear.
Where a rocking arm is employed for operating the draw knives and catches, I
mount on the cross shaft of the said arm two tappets which alternately act on
pendant arms connected with the link of the draw bars so that the one tappet
moves out its draw bar and retains it until (when a change is to be effected; the
other knife has secured a hold on the catch or catches to be drawn and thereby
there is avoided that partial dropping of the jacks common to dobbies as heretofore
constructed and operated. A return spring acts on the tappet pendant arms, so as
to keep the latter up to the tappets.
Thirdly. To improved apparatus for operating the change shuttle box motion
comprises a cross shaft at the back of the loom on which shaft are spaced gear
wheels driving and locking a lower shaft by spaced wheels. On the lower shaft
are spaced wheels each having two series of teeth side by side and each having
locking devices which hold the wheel to the position it has being moved or set to.
The side movement of these wheels is effected through the agency of sliding bars
there being one of such bars to each of the wheels. The slides are operated by
means of one arm of a bell crank lever there being one of such levers to each wheel
and the said levers are controlled by the pattern or peg mechanism acting on the
upper arms of the levers. On the axis of the shaft of the lower spaced wheels is a
strap eccentric a rod from which extends downwards and the lower end is attached
to the main or ordinary box lever at the lower part of the loom. When five or
more boxes are to be employed in lieu of the ordinary main lever there is a com-
pound lever and additional spaced wheels and bellcranks operated as described.
The clutch box and upright shaft already referred to in connection with the
dobby serve to throw out the shuttle changing mechanism so that the loom can be.
reversed without moving the boxes or the boxes can be moved without other parts
of the loom.
The mechanism it will be understood is applied to both ends of the loom for the
two series of boxes.
Where the shuttle boxes are to be operated direct from the dobby I employ a
chain cord or racks passed over a pulley mounted on the upper arm of a bell crank
or straight lever having a fulcrum about midway its length the lower arm of the
lever is connected to the ends of a rod extending across the front of the loom and
near the top rail. To the other end of the rod is attached a bell crank lever and
the latter by connecting rod is attached to the box or main lever for operating the
shuttle boxes. So long as the knife of the dobby is engaged with the draw hook
the particular box brought in line with the shuttle race will be steadily held in that
position until a change is indicated.
It will be understood that the number of hooks, levers, cranks and rods as
described are in accordance with the number of cells or shuttle boxes of the loom.
The main or shuttle box lever is a broken back or escapement lever consisting of
two lengths jointed or hinged together, the joint being secured in its working

page_text: position under ordinary conditions by a spring which gives way when any undue
or extra strain is put upon the lever and thus prevents breakage.

According to this my said invention the improved apparatus for changing the
position of the pattern barrel, so as to bring another series or line of holes of the
latter under the needles the pattern barrel having additional lines of holes for this
purpose, is constructed as follows (see Figs. 1-2.)
:-
I mount on a stud 1 fixed into the frame work of the dobby a disc peg wheel or
peg pulley 2 at the back of which and fast thereto is a ratchet wheel 3 operated by
a catch 4 carried on the lever 5 the lower end of latter being connected to and
worked by a pusher rod 6 from the T or rocking lever 7. Carried on a cross
shaft 8 is a rocking arm 9 the lower part of which provided with a slot 10
through which the axis 11 of the cylinder or peg barrel 12 is received and the
upper end of the arm 9 carries a runner 15.
The cylinder or barrel 12. is carried in slots 13-13 of two arms 14. (one at each
side of the dobby) as ordinary but such slots 13-13 are elongated (see Fig. 2)
for purpose hereinafter described.
The action is as follows:-As the dobby is worked as ordinary the T or rocking
lever 7 operates the pusher rod 6. above referred to and moving the lever 5 on its
fulcrum also moves the catch 4. and on the return movement of the T or rocking
lever 7 the ratchet wheel 3 and peg disc or peg pulley 2 is turned one tooth and so
long as there is not any peg in the disc or pulley 2 or large link in the pattern
chain 16 the cylinder 12. will have its ordinary motion only but when a peg or
large link in the pattern chain 16 occurs the latter will act on the runner 15 at the
upper end of the rocking arm 9. and the lower and slotted end 10. will carry the
cylinder 12 forward a short distance so as to bring another line of holes under

page_text: the needles 17 in which position it will be retained so long as the pegs or chains
indicate for that position of the cylinder but soon as a blank occurs the rocking
arm 9 will be returned to its original position through the action of a return
spring 18. Both ends of the axis 11. of the cylinder 12 are carried in a slotted
pendant arm 14 and each slot 13 allows the cylinder 12 to rise and fall when
operated in the ordinary manner.
The peg disc or pulley may be covered with a pattern chain such as 16 or by
pegs which will operate the runner 15 on the rocking arm 9 and also the barrel 12
as described.
The catch 4. is provided with a finger 19 which rests on the upper end of the
needle 17 and as the latter is operated by the cylinder 12 so is the catch 4 moved
in or out of gear with the ratchet wheel 3.
Secondly. To improved means of operating the dobby (see Sheet 2). Instead of
the Trocking arms employ a series of spaced wheels 1. 14 14 operated by bevel
gear 2 from an upright shaft 3. The spaces 4 in the wheel 1 gives a dwell so that
one knife say 5 shall in all cases get hold of its hook or hooks before the other
knife 6 releases its hook or hooks, and so the partial dropping of the jack levers is
prevented.
Locking pieces 7. 7 are cast to the wheels 14 14 and these locking pieces lock on
the rim 8 of the centre or driving wheel 1 when a blank space on the wheel 1
occurs, and when the teeth of the centre wheel 1 again come in contact with the
teeth of the outer wheels 14 14 the locking pieces are turned from the rin in the
ordinary way and the wheels 1A 14 continue to revolve.
On each wheel 14 14 is cast or formed a crank or arm 9 which carrys the
link 10. 10 attached respectively to the upper and lower draw knives or bars 5. 6.
In connection with the upright shaft 3. and bevel gear 2. is a cross shaft 12. bevel
gear 13 and hand wheel 14 by means of which the dobby can be turned by hand in
either direction that is backwards or forwards without moving other parts of the
loom the upright shaft 3 being by a clutch box 14 on the said shaft 3 first thrown
out of gear. The shaft 3 is driven by bevel gear 15 from the tappet or crank
shaft 16 of the loom. A hand lever 17 and catch and rack 18 are preferably
provided for controlling the clutch box 14*.
Where a rocking arm 19 is employed (see Fig. 5.) for operating the draw knives
or bars 5. 6. and catches, I mount on the cross shaft 20 of the said arm 19 two
tappets 20, 21. which alternately act on pendant arms 22. 22 connected with the
links 10. 10 of the draw bars 5. 6. so that one tappet say 21 moves out its draw bar 5
and retains it in the out position until (when a change is to be effected) the other
knife or bar 6 has secured a hold on the hooks or catches to be diawn out, and
thereby there is avoided that partial dropping of the jack levers common to lobbies
as heretofore constructed and operated. Return springs 23. 23 act on the tappet
pendant arms 22. 22. so as to keep the latter up to the tappets 20" 21.
Thirdly. To improved apparatus for operating the change shuttle box motion
(see Sheets 3. 4. 5. 6 and 7) which comprises a cross shaft 1 at the back of the loom
on which shaft 1 are spaced gear wheels 2. 2 driving and locking a lower shaft 3 by
means of spaced wheels 4. 4. The spaced wheels 4. 4. on the lower shaft 3 each
have two series of teeth 5. 18. parallel to each other (see detail Sheet 6) and each
have a locking device 6 which holds the wheel 4 to the position it has been moved
or set to. The side movement of the wheels 2. 2. is effected through the agency of
The
sliding bars 7. 7. there being one of such bars 7. to each of the wheels 2.
sliding bars 7. 7. are operated by means of an arm or crank lever 8 there being one
of such levers or arms 8 and slides 7 to each wheel 2 and each slide 7 is provided
with a finger or rod 9. the end of which is received in the groove 10 formed in the
collar or boss 11 of each wheel 2 the latter having key beds formed in them for the
reception of the key 12 formed on the shaft 1. (see Fig. 8 and detail Sheet 6) and
the said levers or arms 8 are controlled by the pattern or peg mechanism 13 acting
on the upper arms of such levers. On the axis or shaft 3 of the lower spaced
wheels 4. 4. is a strap compound eccentric 14 as ordinarily used for change box

page_text: looms a rod 15 from which extends downwards and the lower end is attached to the
main or ordinary box lever 16. at the lower part of the loom.
When five or more boxes are to be employed in lieu of the ordinary main lever 16
there is a compound lever (see Fig. 12) and additional spaced wheels and bell cranks
operated as herein described.
The wheel 4. shewn in detail on Sheet 6 has two blanks 17. 17. and two teeth or
lugs 18. 18 and each of such teeth or lugs 18 extend part way only across the
wheel 4. the remaining space forming a recess or blank 17 so as to allow the upper
wheel 2 which drives it to revolve without turning the lower wheel 4 until the
upper wheel 2 is slided on its shaft 1 as above described and comes in contact with
the tooth or lug 18 starting the wheel 4 when the teeth 5 turn the wheel 4 half a
revolution and the wheel 4 again stops when the wheel 2 arrives at the next blank 17
on the opposite side of the wheel 4. the wheel 4 remaining stationary until the
wheel 2.is again slided back on its shaft 1 and comes into contact and gear with the
tooth 18 and teeth 5 on the other side of the wheel 4 and so on.
The tooth or lug 18 is made larger and stronger than the remaining teeth 5 in
order to more certainly ensure the teeth of the wheel 2 operating the wheel 4, and
preventing breakage when the wheel 2 is slided, as above described, so as to engage
therewith, but it is not absolutely necessary that the tooth or lug 18 should be
larger as a tooth or teeth of similar size to the teeth 5 would also be workable, the
first tooth of the wheel 2 coming in contact with the lug or tooth 18 the wheel 4
will be slightly turned thereby and the remaining teeth of the wheel 2 gear with
the teeth 5 of the wheel 4 the latter continuing the revolution until arriving at the
blank 17.
The shaft 1 is driven by bevel gear 19 upright shaft 20 and bevel gear 21 from
the tappet or crank shaft of the loom and the wheels 2 drive the wheels 4 in the
manner above described and (when a compound eccentric 14 is employed as shewn
by Figs. 7 and 8 and details on Sheet 8) the box lever 16 and the shuttle boxes 23
(whether circular or rising and falling) are operated as indicated by the pattern or
peg mechanism 13. The first wheel 4 (shewn at the left hand side of Figs. 7
and 16) is keyed on the shaft 3 as is also the small eccentric A of the compound
eccentric 14.
The second and middle wheel 4 is cast to a long collar 34 to which is attached
the eccentric B which by pin 7 drives the eccentric D. of the compound eccentric 14
and the third wheel 4 has a long collar or boss 4B to which is cast the fork or clip 5
which by the pin or stud 64 drives the eccentric C of the compound eccentric 14
the pin or stud 6ª moving up and down the slot of the fork or clip 54 when other
of the eccentrics are operating. So that as each eccentric is operated by its
wheel 4 a greater or less amount of motion is imparted to the rod 15 and conse-
quently more or less lift given to the box rod 16 and boxes according as a larger
or smaller eccentric is brought into operation. It is to be understood that the
compound eccentric 14 forms no part of my invention as the use of such eccentrics
for similar purposes is well known.
Fig. 7 shews the pattern or peg mechanism 13 driven by bevel gear 24 shaft 25
and bevel gear 26 but it will be obvious that this mechanism may be driven in
various ways as for instance the cylinder 13 may be mounted on the shaft or axis of
the cylinder of the dobby (see Figs. 8 and 9).
A clutch as above described may be employed for throwing the bevel gear or
shaft 25 out of gear when desired.
In Fig. 7 is also shewn an extra wheel 2ª on the shaft 1 operated and operating
an extra spaced wheel 4* on the lower shaft 3 in the manner herein above described
the wheel 4 having a strap eccentric 5ª cast to it and the in turn operates the gear
wheel 8* on the cam shaft 9* causing the latter to revolve in either direction for the
purpose of sliding the picking tappet on the tappet shaft in the usual and well
known manner.
- In Figs. 10 and 11 the several parts are operated in the manner herein described
but are shewn in a slightly modified form two ordinary strap eccentrics and

page_text: a compound box lever being employed in lieu of the compound eccentric shewn in
Figs. 7 and 8. The wheels 2 are slided on their shaft 1 by the pattern mechanism 13
and appliances connected therewith and drive the wheels 4, 4* on the lower shaft 3
on which shaft the strap eccentric 27 is keyed as also is the wheel 4 but the
wheel 4. is loose on the shaft 3 the strap eccentric 28 being cast to the said wheel.
From these strap eccentrics 27. 28 extend the rods 29. 29. their lower ends being
connected to the ends of a compound box lever 30 (see Fig. 12.) by means of which
the shuttle boxes are operated in the ordinary manner.
It will be obvious that the lower wheels 4 may be slided on their shaft 3 and the
upper wheels 2 remain stationary as regards lateral movement, and that various
locking devices may be employed for locking the wheels in the position to which
they have been moved such for instance as the ordinary hammer head 30 and
spring device for pressing and locking on a flat portion 31 of the wheels 4.4 and
shewn by Fig. 7. of the drawings or the well known rim locking device as shewn
by Figs. 10. and 11 of the annexed drawings, and also that different numbers of
wheels, and various eccentrics may be employed accordingly to the number of boxes
to be operated.
The clutch box and upright shaft already referred to in connection with the
dobby serve to throw out the shuttle changing mechanism or peg or pattern
mechanism so that the loom can be reversed without moving the boxes or the boxes
can be moved without other parts of the loom.
The mechanism it will be understood is applied to both ends of the loom for the
two series of boxes.
Where the shuttle boxes are to be operated direct from the dobby (see Fig. 13.)
I employ a chain or cord 1 passed over a pulley 2 mounted on the upper arm of a
bell crank or straight lever 3 having a fulcrum 4. about midway its length, the
lower arm of the lever is connected to the end of a rod 5. extending to and attached
to one end of the box lever 6.
For operating the shuttle boxes at the other end of the loom a rod 7 extends
across the front of the loom near the top rail and the other end of the said rod 7. is
attached to a bell crank lever 8 and the latter by connecting rod 9 is attached to
the box or main lever 64 for operating the shuttle boxes. The chain or cord 1 is
connected at one end to the lever 10 of the dobby and the other end of the chain 1
is attached to the lever 11. of the dobby, and it will be seen that the lever 10 is
longer than the lever 11 and that if the lever 10 is operated by the dobby a greater
amount of motion will be given to the chain 1 box lever 6 or 64 and also to the
shuttle boxes than if the lever 11 only were operated and if both levers 10. 11. are
operated at one and the same time a still greater amount of motion will be given
the shuttle boxes.
So long as the knife of the dobby is engaged with the draw hook the particular
shuttle box brought in line with the shuttle race will be steadily held in that
position until a change is indicated.
It will be understood that the number of hooks, levers, cranks and rods as
described are in accordance with and as required by the number of cells or shuttle
boxes of the looms.
The main or shuttle box lever herein described may be a broken back or escape-
ment lever (see Figs. 14. 15) consisting of two lengths 13. 14 jointed or hinged
together at 15 the joint being secured in its working position under ordinary
conditions by a spring 16 and hammer head 17. The latter being received in a
notch or groove 18 in the part or length 14 of the lever and the spring 16 will be
compressed, and the hammer head 17 will release the holding notch 18 and the lever
will give way at the joint 15 when any undue or extra strain is put upon the lever,
and thus prevents breakage.
For treading up the shuttle boxes without moving other parts of the loom a
treadle 19 is attached by link 20 to the end of the lever 14, and by depressing the
treadle 19 the spring 16 is compressed the lever 14 moving on the joint 15 the box
rod 21 and boxes being raised. A spring 22. tending to draw down the treadle 19.

page_text: and raise the end 14. of the box lever assists the latter in raising the shuttle boxes
when operated by the above described mechanism.
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. The disc or peg wheel 2 runner 15 slotted rocking arms 9 double slotted
arms 14 and the cylinder or barrel 12 all in combination, operated and operating in
the manner, and for the purpose herein described and as illustrated by Sheet Ĭ of
the annexed drawings.
2. In a dobby the use of spaced wheels such as described in combination with
the means of operating the same as and for purpose herein fully set forth and

the eccentrics as described as and for the purpose herein set forth and substantially
as illustrated by Figs. 7. 8. 9. 10 and 11 of the annexed drawings.
5. For operating the shuttle boxes direct from the dobby I claim the combination
of parts herein described and illustrated by Fig. 13 of the annexed drawings.
6. The broken backed or escapement lever in combination with link 20 and
treadle 19. for lifting the boxes as herein described and illustrated by Figs. 14
and 15. of the annexed drawings.
