IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1869

page_text: LETTERS PATENT to Richard Longden Hattersley, of Keighley, in the
County of York, Machine Maker, and James Hill, of the same
Place, Overlooker, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING,"
Sealed the 8th April 1870, and dated the 12th October 1869.
PROVISIONAL SPECIFICATION left by the said Richard Longden
Hattersley and James Hill at the Office of the Commissioners of
Patents, with their Petition, on the 12th October 1869.
We, RICHARD LONGDEN HATTERSLEY, of Keighley, in the County of
York, Machine Maker, and JAMES HILL, of the same Place, Overlooker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING," to be as follows:-
The first part of this Invention relates to the stopping motion in
looms with revolving shuttle boxes for weaving textile fabrics of odd
or even picks at will, and the improvements consist in the application
of two forks hinged on brackets fixed to the front of the batten or slay-
board, one at the entrance of each shuttle box, the prongs of which are

page_text: straight and project across and sufficiently above the shuttle race for
the shuttle to pass under them, both being connected by a rod so as to
be actuated simultaneously, and one of the said forks having a finger
(without hook) to act direct upon the knocking-off lever or handle of the
loom which operates the strap guide, and in the employment to act in
conjunction therewith of two other forks carried on rods capable of
sliding in brackets or otherwise fixed to the back of the said slayboard,
such forks also having straight prongs to project across the said shuttle
race, and so set and operated as to pass in betwixt the prongs of the
other forks when raised or lowered, and to embed themselves in the
slayboard when lowered. These back forks are actuated or raised quickly
by the action of a tappet, cam, excentric, or other suitable means
immediately after the shuttle has been picked across, when if weft be
present on either side the prongs of one of the back forks will lift it
against the prongs of one of the front forks, and thereby depress the
finger or the other end of the said front forks, so as to miss or not act upon
the knocking-off lever and thereby not operate the strap guide; but if no
weft be present the prongs of the said back forks will pass betwixt those
of the front forks and consequently not act thereon, when the finger of
the said front fork by the motion of the slayboard will act on the
knocking-off lever (which is suitably constructed for that purpose), and
will thereby stop the loom sooner than the ordinary stopping motion.
Secondly. The Invention relates to an improved driving motion
arranged for "pick and pick" and other looms which consists in the
application of a loose socket or boss on the crank shaft or on a separate
stud revolving at a much greater speed than the crank shaft, having fast
and loose pullies, break wheel, and a pinion or small toothed wheel fixed
on the tappet shaft, and on the said tappet shaft is fixed an excentric wheel
gearing with another similar wheel fixed on the crank shaft, and these
wheels are so arranged or set that a slow motion is given to the crank
shaft when the crank is passing the back centre, thus giving a "dwell "
to the slayboard and jacquard, and allowing more time for the shuttle
to pass gently through the warp and for the weft forks to act. It also
enables the driving strap to be changed from the fast to the loose pulley
in one-eighth part of a revolution of the crank shaft when the weft is
broken, and thereby the loom is stopped with the aid only of the ordinary
break motion before the slay arrives at the cloth, and consequently
before any change is effected in the shed or the shuttle boxes or the

page_text: jacquard or other indicating motion, and thus no slackening of cloth
or returning of cards is required.
Thirdly. The Invention relates to the means of picking the shuttles
in any order that may be required, and the improvement consists in
having the picking cones or pullies to slide on their carrying studs in
and out of contact with the picking tappets, and in having a slide
rod with a clip fork at each end which operate upon a swing fork
attached to each picking shaft and to each picking cone or pulley,
the said slide rod being operated by a scrowl tappet in which are
fixed pegs acted upon as required by two catches attached to a lever
worked by a cam or excentric fixed on the low shaft of the loom, the
said catches being put into operation by jacquard or other indicating
apparatus.
Fourthly. The Invention relates to means or apparatus for clearing
or removing all the shots of weft out of the way of the weft forks except
the last shot as applied to looms having change boxes and using a series
of shuttles therewith, which consists in a hook or finger attached to an
endless belt or chain carried on pullies mounted on studs fixed to the
front of the slayboard, also passing round a pulley fixed on a cross shaft
caused to oscillate at each pick, which shaft is placed intermediate of
the loom and about in line with the axis of the going part, this shaft
being actuated by tappet or excentric and levers from either the tappet
shaft or crank shaft as most convenient, one of such fingers being placed
at each side of the fabric and capable of adjustment to the edges thereof
to suit the various widths of fabrics to be produced and are operated
simultaneously.
Fifthly. The Invention relates to. revolving shuttle boxes required to
skip or change from one shuttle box to the next, second, third, or any
other box in the series from it, and consists in the application of cams
or excentrics of different lifts which operate upon separate levers, and
these levers operate upon separate catches, and any one of these catches
may be put into position by the jacquard or other indicating apparatus.
The fulcrum ends of these catches are attached to one lever having having
its fulcrum at or near its centre, and to the other end of the said lever is
attached a double rack bar or two single racks with teeth suitably
formed, which when required is capable of being placed firmly in gear
with either side of a spur wheel fixed on the shaft of the revolving
shuttle box by means of an arrangement of excentric lever and catches
2

page_text: when the said catches are put into position by the jacquard or indicating
apparatus. The said rack bar or bars not being released from the spur
wheel until the moment it has drawn over the revolving box exactly to
its required position, it being impossible for the shuttle box to overrun
itself or fall short of the intended distance.
Sixthly. The Invention relates to an improved arrangement for
arresting the momentum of the revolving box at the proper time, and
for preventing its being overdrawn, more particularly when the shuttle
box is required to revolve more that the distance of one compartment,
and consists in the application of a star wheel or a circular plate
having a corresponding number of projections to the number of com-
partments in the shuttle box fixed on the revolving box shaft and
two lock catches so placed that their loose ends are in contact with the
projections on each side of the said star wheel or circular plate when the
shuttle box is stationary, but when the shuttle box is operated the
ordinary "hammer" or T head which holds the shuttle box firm is
drawn out of contact with the star wheel, and when so drawn out it
moves back the two lock catches out of the way of the said projections,
and thus allows the shuttle box to revolve in either direction to the
required distance; the "hammer" or T head being then liberated at the
proper moment returns to the star wheel, and at the same time allows
the two lock catches to drop into contact with the proper projections on
the circular plate, and thus firmly arrests the momentum of the shuttle
box at the proper moment whatever number of compartments may have
been drawn over.
Seventhly. The Invention also relates to an improved arrangement
for preventing the shuttle boxes from being changed from one compart-
ment to another after the weft is broken in any compartment in which
the shuttle may be operating, and consists in having a finger or small
lever attached to the ordinary rod used for lifting off the catch which
turns the card cylinder of the indicating motion. This finger is so
arranged as to prevent the levers from being operated by the cards, and
thus preventing the shuttle boxes being again changed until the weft is
replaced, which avoids the necessity of the weaver having to turn over
the shuttle boxes to seek the broken weft thread and then replace them
in proper position.

after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Longden Hattersley and
James Hill, do hereby declare the nature of our said 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
Sheets of Drawings (that is to say) :-
The first part of this Invention relates to the stopping motion in
looms with revolving shuttle boxes for weaving textile fabrics of odd or
even picks at will, and the improvements consist in the application
of two forks hinged on brackets fixed to the front of the batten or
slay board, one at the entrance of each shuttle box, the prongs of which

page_text: ordinary break motion before the slay arrives at the cloth, and
consequently before any change is effected in the shed or the shuttle
boxes or the jacquard or other indicating motion, and thus no
slackening of cloth or returning of cards is required.
Thirdly. The Invention relates to the means of picking the shuttles
in any order that may be required, and the improvement consists in
having the picking cones or pullies to slide on their carrying studs in
and out of contact with the picking tappets, and in having a slide rod
with a clip fork at each end, which operate upon a swing fork attached
to each picking shaft and to cach picking cone or pulley, the said
slide rod being operated by a scrowl tappet in which are fixed pegs
acted upon as required by two catches attached to a lever worked by a
cam or eccentric fixed on the low shaft of the loom, the said catches
being put into operation by jacquard or other indicating apparatus.
Fourthly, The Invention relates to means or apparatus for clearing or
removing all the shots of weft out of the way of the weft forks, except
the last shot as applied to looms having change boxes and using a series
of shuttles therewith, which consists in a hook or finger attached to an
endless belt or chain carried on pullies mounted on studs fixed to the
front of the slayboard, also passing around a pulley fixed on a cross
shaft caused to oscillate at each pick, which shaft is placed intermediate
of the loom and about in line with the axis of the going part, this shaft
being actuated by tappet or eccentric and levers from either the tappet
shaft or crank shaft as most convenient, one of such fingers being
placed at each side of the fabric and capable of adjustment to the edges
thereof to suit the various widths of fabrics to be produced and are
operated simultaneously.
Fifthly. The Invention relates to revolving shuttle boxes required to
skip or change from one shuttle box to the next, second, third, or
any other box in the series from it, and consists in the application.
of cams or eccentrics of different lifts, which operate upon separate-
levers, and these levers operate upon separate catches, and any one of
these catches may be put into position by the jacquard or other
indicating apparatus. The fulcrum ends of these catches are attached
to one lever having its fulcrum at or near its centre, and to the other
end of the said lever is attached a double rack-bar or two single
racks with teeth suitably formed, which when required is capable of

page_text: being placed firmly in gear with either side of a spur wheel fixed on the
shaft of the revolving shuttle box by means of an arrangement of
eccentric, lever, and catches, when the said catches are put into position
by the jacquard or indicating apparatus, the said rack bar or bars not
being released from the spur wheel until the moment it has drawn over
the revolving box exactly to its required position, it being impossible for
the shuttle box to overrun itself or fall short of the intended distance.
Sixthly. The Invention relates to an improved arrangement for
arresting the momentum of the revolving box at the proper time, and for
preventing its being overdrawn, more particularly when the shuttle box
is required to revolve more than the distance of one compartment, and
consists in the application of a star wheel or a circular plate having a
corresponding number of projections to the number of compartments in
the shuttle box fixed on the revolving box shaft, and two lock catches
so placed that their loose ends are in contact with the projections on
each side of the said star wheel or circular plate when the shuttle box is
stationary, but when the shuttle box is operated the ordinary "hammer"
or T head which holds the shuttle box firm is drawn out of contact with
the star wheel, and when so drawn out it moves back the two lock
catches out of the way of the said projections, and thus allows the
shuttle box to revolve in either direction to the required distance; the
"hammer or T head being then liberated at the proper moment returns
to the star wheel and at the same time allows the two lock catches to
drop into contact with the proper projections on the circular plate, and
thus firmly arrests the momentum of the shuttle box at the proper
moment whatever number of compartments may have been drawn
over.
"
Seventhly. The Invention also relates to an improved arrangement
for preventing the shuttle boxes from being changed from one compart-
ment to another after the weft is broken in any compartment in which
the shuttle may be operating, and consists in having a finger or small
lever attached to the ordinary rod used for lifting off the catch which
turns the card cylinder of the indicating motion. This finger is so
arranged as to prevent the levers from being operated by the cards and
thus preventing the shuttle boxes being again changed until the weft
is replaced, which avoids the necessity of the weaver having to turn over
the shuttle boxes to seek the broken weft thread and then replace them
in proper position.

page_text: The first part of this Invention will be understood by reference to
Figs. 1 and 2, wherein A' is a bracket fixed to the batten or slayboard A³,
and there are two of these brackets to each loom one on each side of the
reeds pace, as shewn in Fig. 2. In each bracket is hinged a weft fork
the ends of which A³ have three or more prongs; the other ends A* are
single and the fulcrums are near the centre of each fork; these two
forks are coupled together by a light wood or metal roller A³ affixed to
the slayboard in small brackets with wire links or rods A. A tappet or
eccentric A' is fixed on the low shaft of the loom, and a lever A³ is
hinged to the framing at A', and to the other end of said lever is jointed
a connecting arm A, to the lower end of which arm is jointed a stud
capable of sliding in a slot of the casting A" which is attached to the
sword arm, and to the same stud is jointed or fixed a connecting arm A"
which is jointed to a short lever A", and which lever is fixed on the
shaft A. This shaft extends from sword to sword and oscillates in
brackets A supported from or fixed to each sword. On this shaft are
also fixed two short levers A", one underneath each weft fork, and on
each lever rests a small upright rod A steadied by brackets fixed on each
sword. On the top of each of these rods is fixed a horizontal weft fork A",
the prongs of which are capable of passing betwixt the prongs of the
forks A, and to the handle A" is fixed a stud pin A", in which is hinged
a spring catch which will give way in case the handle A" should be
held fast by the weaver or otherways at the time of action. When the
lever A is depressed by the tappet A' it operates on the connecting
arms and levers A", A", A", and A", and allows the two forks A" to
fall into the grooves formed for them on each side of the reed space of
the slayboard, and when the shuttle has been thrown these forks A" are
by the springs A" raised to the position shewn in the Drawings, when if
no weft be present (or when the weft is used up or broken) they will
have passed through the prongs of the forks A³ and the other end A*
will have maintained its position, and by the action of the slayboard
will be brought in direct contact with the spring catch in the stud
pin A", which instantly knocks off the handle A", transfers the strap
from the fast to the loose pulley, and thereby stops the loom much
sooner than in the ordinary way, as the fork acts immediately after the
shuttle has passed, but in the ordinary plan it cannot act until the
slayboard has passed its front centre or is making the stroke upon the
cloth; but if on the contrary the weft thread should lay unbroken on
the shuttle race it will be taken by the forks A" on whichever side

page_text: of the loom or shuttle race it may be and lifted against the prongs A³
of the other forks, and thus depress the ends A', which will thus pass
under the spring catch in the stud pin A", whereby the loom will not
be stopped.
The second part of the said Invention is shewn in Figs. 3 and 4, where
B is a small spur wheel with long boss which works loose on the crank
shaft of the loom ;] on this boss the driving pullies B¹ and the break
wheel B' are fixed; B³ is a large spur wheel fixed on the low shaft, and
on the opposite end of the low shaft is fixed an eccentric or eliptical
spur wheel B', which gears into a similar one B³ fixed on the crank
shaft. By this arrangement the slayboard is made to dwell or is decreased
in speed at the time when the shuttle is passing through the shed
(which is of great advantage in broad looms), and the belt can be
changed from the fast to the loose pulley during less movement of the
slayboard or during a lesser part of the revolution of the crank shaft
than by the usual way of driving looms, the driving pulley and break
wheel making three, four, or more revolutions for every single stroke of
the slayboard, so that the break has more power to stop the loom in
very much shorter traverse of the slayboard when the weft is broken or
otherwise absent. The small spur wheel B and the break wheel B³ can
be placed on a separate stud, and the large wheel B³ on the crank shaft
if preferred.
The third part of this Invention is shewn in Figs. 3, 5, 6, 7, and 8,
wherein C is a lever with its fulcrum at O¹, and a spring joint near its
centre which is kept in position by the spring C². An eccentric or
tappet C³ is fixed on the low shaft of the loom (but in some cases wo
may fix this tappet on the crank shaft), and two catches C and C³, are
jointed to the said lever C, and two cords or small rods C and C³ connect
the two catches with the jacquard or indicating apparatus. Cs is a
scrowl having an oblique slot on its face or outside rim; above this
scrowl is a rod C extending across the loom, on which rod is fixed a pin
or stud Co which takes into the slot of the scrowl, and on the same rod
are also two guide plates or fingers O" and C" which take hold of two
swing forks c¹s and c" which can either have their fulcrums C and C¹,
attached to the upright picking shafts C" and C¹³, or to the framing of
loom, as shewn in Fig. 7, which take into the grooves of the picking
cones C and C, and by the action of these forks the said cones are
placed either in or out of position to be actuated by the picking tappets

page_text: C and C, the inner circles having the picking noses and the outer
circles being without. The operation is as follows, namely. The lever C
being operated every pick by the tappet C³ takes with it the two catches
O and Cs, and whenever either of these catches are put into position by
the jacquard or indicating apparatus the scrowl Cs is made to partially
revolve and by means of the pin C causes the rod C to slide in its
bearings; this takes with it the guide plates C" and C" and the forks C¹³
and C, which cause each picking cone to slide on its stud, the one into
and the other out of contact with the nose of its respective picking
tappet, and thus the shuttle will be thrown from either side when and
as may be required. In some cases we adopt the following arrangement,
as shewn at Figs. 7 and 8, to operate the scrowl C³ for changing the pick,
namely, D' is a tappet fixed on the low shaft of the loom; D is a lever
having its fulcrum at D³, to this lever is jointed a catch hook D' having
its fulcrum at D³, and to the lever D' is also jointed a lever D', the
bottom end of which slides in a slot of the bracket D'. A small lever D³
is jointed to the lever D', which by means of the spring D° is kept pressed
on to a pin fixed in the catch hook D'. The levers D and D" have
their fulcrums at D, and their ends D₁ are in connection with the card
motion D, and when operated thereby either the lever end D is pressed
against the upper end of the catch hook lever D', and causes the lower
or catch end to come in contact with or hook on to the pin D¹³ of the
scrowl C³, or the lever D" is pressed against the lower part of the catch
hook lever D' and causes the other side of the catch to take on to the
other pin D of the scrowl C³, and thus when the tappet D' operates on
the lever D' the catch hook D' is made to turn the scrowl one way or
the other as desired, and the change in the pick is obtained in the same
way, as described in Figs. 3, 5, and 6.
The fourth part of the Invention is shewn in Figs. 9 and 10, wherein E
is a tappet or cam fixed on the low shaft of loom; E¹ is a lever having
its fulcrum at E³, and to the opposite end of this lever is attached a cord
or strap E³, the other end of which cord or strap goes round and is
secured to a small pulley E* fixed on a small shaft or arbour E³, on
which is also fixed a large pulley E, the whole being. fixed to an arm
or stay Es which oscillates with the slayboard. E' are india-rubber or
other springs held by hooks or otherwise to the low rail E, and are
connected to straps E" and E" carried over the four pullies E", E", E",
and E and secured to the pulley E. On the straps E" and E arc

page_text: fixed two fingers or hooks E, and E" which when the lever E' is
operated by the tappet E the pulley E' is made to partially revolve and
thus draw the straps E and E¹ partially round its circumference,
bringing the two fingers or hooks Els and E just underneath each edge
of the cloth which is being woven, and immediately after each shuttle
is thrown the fingers are drawn by the springs E' into the position shewn
in Fig. 9, taking with them all the weft threads on both sides of the loom
quite clear of the weft forks, except the last weft thread thrown, which is
then left unentangled with any of the other threads laying between the
edges of thecloth and the shuttle boxes and quite free for the weft fork
to act upon it on either side. Fig. 11 is a section of the picking cone.
The fifth part of the said Invention will be understood by reference
to the several figs. and letters of reference as follows, viz. :-Fig. 12
is an end elevation of a loom; Figs. 13 and 14 are two views of
a series of five tappets or cams J fixed on the low shaft of the
loom J¹ (Fig. 12), and J' is one of four levers J, J, J, and Js (Fig. 20),
each having a small pulley working on a stud fixed near the centre
of each lever, and being at such distances from each other as to
correspond with the tappets or cams a, b, c, d, (Fig. 13), and to lay
thereon; the said levers J, J, J, and J' have their fulcrums at G and
have slots and recesses at H, in which the catches Je, J", J, Jo, J, and
J (Fig. 21) stand in an upright position, as shewn by J (Fig. 12),
and all of them at Fig. 21. The catches J, J', and J' have their
fulcrums jointed to the lever J" (see Figs. 12, 15, and 21). The fulcrums
of the lever J, J, and J¼ (see Fig. 15) are on a stand J16 (sce
Figs. 12, 15, and 17) fixed to the framing of the loom. To the other
end of the lever J" is jointed the double rack bar J" (see Figs. 12 and
17), having in its upper part two rows of teeth (as shewn more clearly
in Fig. 16), which teeth correspond with a pinion wheel J" (Figs. 12
and 16) fixed on the axis J" (Fig. 16) of the shuttle box, but the space
between these two rows of teeth in the rack bar is such that the rack
bar can be worked up and down when required without touching the
pinion wheel J. The catch J' (Fig. 21) is jointed to the lever J's, and
to the other end of the said lever is jointed the shank of a T head or
presser J (Figs. 17 and 19). J" (Figs. 16 and 19) is a star wheel
having six projections to correspond with the number of compartments
of the shuttle box, and is fixed on the axis J of the shuttle box. On
the upper part of the catch J (Fig. 21) is fixed a small finger Ja,

page_text: which projects in front of the two catches J" and J", so that neither
of the said catches can be put into operation without at the same time
putting the catch J into operation. To the lever J (Fig. 15) is
jointed the catch Ju, (Fig. 21), and this lever has its fulcrum on a stud
at J fitted into a bracket J" fixed to the framing of loom; and into
the other end of the lever J" is fixed a stud J (Fig. 15), which takes
into a slot of the lever J". The catch J" (Fig. 21) is jointed to the
lever J (Figs. 15 and 21), and to the other end of said lever is jointed
the connecting rod J (Figs. 12, 16, 17, and 18), to the upper end of
which connecting rod is jointed the lever J" (see Figs. 12, 16, and 18),
which is formed so as to have a bearing upon the lower or under part
of the boss of the spur wheel J. The under side or edge of this
lever J is flat and is kept in position by the lever J (Figs. 12, 16,
and 18) being kept pressed against it by means of the spring J", which
is attached to it and the framing J" (see Figs. 12, 16, and 18). The
lever Js has its fulcrum on a stud Ja fixed to the framing J, Figs. 12, 16,
and 18. The lever J" has two projections F, F', (Figs. 16 and 18), which
fit inside two smooth flanges F2 and F3 of the rack bar J" (see Figs. 17
and 18), and these projections F, F', are for operating on the rack bar for
putting the same into and out of gear with the pinion wheel J18, so that
the said rack bar can be put into gear on either side of the pinion wheel J18
when required to operate the shuttle box, and when the shuttle box
is at rest the rack bar teeth are quite clear of the teeth of the pinion
wheel J. J (Fig. 12) is one of five levers J, 33, 34, 35, and 36
(see Fig. 21) having their fulcrums on a stud fixed in a bracket J*7
attached to the framing of the loom. The lower portions of these
levers K (Fig. 12) are so formed as to come into contact with the
catches J, 7, 8, 10, and 11 when required. The other ends of these
levers J, 33, 34, 35, and 36 have pins at L (Fig. 12) for the cards of
the indicating motion to operate upon when required. J38 is the card
cylinder, and J are the cards. The eccentric cam E (Figs. 13 and 14),
is for operating on the upright lever J", to which is fixed a pin Ju
passing under the levers Ja, 33, 34, 35, and 36 for lifting them clear of
the card cylinder, and jointed to lever J is a catch J for turning the
card cylinder at the time the said levers are raised.
.
The operation is as follows:-The levers J, 3, 4, 5, and J" (Figs. 12
and 201 are onerated every alternate nick by the tannate I and chan

page_text: up
Fig. 12, is turned up with a hole in underneath the peg at L of the
lever Jas (Fig. 12) the peg at the proper time drops into the hole of
the card, and the other end K of the lever J* presses the catch J
(Fig. 12) on to the sneck of the lever J' at H, which is then raised or
operated by the tappet a taking with it the catch J', and by means of
the lever Ju draws down the rack bar J" just sufficient distance to turn
the revolving shuttle box the distance of one compartment, or from one
compartment to the next; but before this can be done the rack bar J
must be placed in contact with the spur wheel J (Figs. 12 and 16),
either on one side or on the other, and the T head or presser J, Figs.
17 and 19 must be drawn away from contact with the star wheel J"
(Fig. 19) so as to allow the shuttle box to turn quite free, which are
accomplished by the following means, viz. :-Whenever a hole is turned
in a card of the indicating apparatus for the lever J* there must
be a hole in the same card for the pin of either the lever J or
the lever J, according to the direction in which the shuttle box is
wanted to revolve if the hole is under the pin of the lever Js (Fig.
21), which is similar and stands in the same position parallel with the
lever J (Fig. 12), the end K of the said lever J presses the catch J¹º
on to the sneck at H of the lever J', which lever is operated by the
. tappet d (Figs. 12, 18, and 14) acting a little in advance of the action
of the tappet a upon the lever J", taking with it the catch J (Fig. 21),
raising that end of the lever J" (Fig. 15), and depressing the other end
of the said lever, which being connected to the rod J* (Figs.
12, 16, and 18) pulls down the lever J", by which means the projection
F¹ of the said lever presses against the smooth flange Fs of the rack
bar J, shown at Fig. 18, and brings the opposite side of the rack bar F
into contact or gear with the spur pinion wheel J", and is held there
until the shuttle box is changed to the next compartment in the
direction of the arrow (Figs. 12 and 16). If the shuttle box is required
to revolve in the contrary direction the hole of the card must be
under the pin of the lever J (Fig. 21) instead of J*, which will act in
the manner described above upon the catch J", which being raised by
the lever J³ raises also the end of the lever Ju, and thus depress
the stud pin J, which being placed in the slot of the lever J" (Fig.
15) depresses that end of the said lever and raises its other end, and
thus by means of the connecting rod J (Figs. 12, 16, 17, and 18)
pushes up the lever J" (Fig. 18), and the projection F of the said lever
presses the rack bar so as to put the teeth on the Fs side of it into gear
"

page_text: with the spur pinion wheel J, and is firmly held there until the shuttle
box is made to revolve the distance of one compartment in the contrary
direction to the one described above and contrary to the arrow in
Figs. 12 & 16.
When it is desired to make the shuttle box revolve in either direction
the distance of two compartments the hole in the card of the indicating
apparatus must arrive under the pin of the lever J" (Fig. 21) instead of
the lever J. This lever will at its K end (Fig. 12) place the catch J'
(Fig. 21) on to the sneck at H of the lever J (Fig. 20) which being
operated by the tappet b, Figs. 13 and 14, moves it and the lever J's a
greater distance than when moved by the lever J' and the catch Je
(Figs. 20 and 21) and the lever J¹ consequently acting in the manner
previously described draws the rack bar J" such a distance as by its
action upon the spur pinion J as to make the shuttle box revolve the
distance of one compartment. When it is desired to make the shuttlo
box revolve in either direction the distance of three compartments the
hole of the card in the indicating apparatus must arrive under the pin of
the lever J³, Fig. 21, instead of the levers J" or J" (all these levers
standing parallel to each other) this lever will then at its end K (Figs. 12
and 21) place the catch Js on to the sneck of the lever J' (Fig. 20)
which being operated by the tappet C (Figs. 13 and 14) moves the
lever Ja greater distance than either of the other two previously
described, and consequently the rack bar J" is drawn or operated to
such a distance as by its action upon the spur pinion wheel Ju as to
make the shuttle box revolve the distance of three compartments in
either direction according as it may be placed in contact with the spur
pinion wheel in the manner previously described. The pins of the levers
J, 33, 34, 35, and 36 are raised above the cards projecting pin J❝ of the
lever J" by the action of the tappet e, and when the lever J" descends
the pins of the levers fall either on to a blank portion of the cards J",
and thereby produce no effect on any other part of the arrangements, or
they fall into a hole in the cards and produce the effect previously
described in making the shuttle box partially revolve. As before stated
when it is desired to make the shuttle box revolve in the manner
described it is necessary that it should be as free from obstruction as
possible, and in order to do this the T head or presser J" (Fig. 19) is
withdrawn from contact with the star wheel J" in the following
manner:Whenever either of the catches J" or J" (Fig. 21) are placed
on the sneck at H of the lever Js (Fig. 20) the catch J, Fig. 21,

page_text: is hooked on to the said lever J' by means of the finger J", and being
then raised by the lever Js (Fig. 20) draws with it the lever J
(Figs. 12 and 15) the other end of the said lever Js being thus depressed
pulls down the T head or presser J* quite clear of the star wheel J",
Fig. 19, and thus leaves the revolving box perfectly free. When the
required movement of the revolving shuttle box has been made the rack
bar J is by the action of the tappets J immediately released from
contact with the spur pinion J", and by the action of the spring J
raised to its former position, as shewn in Fig. 12, the T head or presser
Jo having first returned to its position against the star wheel J" to
steady the shuttle box.
Sixthly. The improved arrangement for arresting the momentum of
the revolving box at the proper time is as follows, viz. :-The projections
on the star wheel J" are formed as shewn at Fig. 19, so that the catches
J and J can rest firmly underneath them; these catches are jointed
on studs J and J" fixed in the box frame J (Figs. 12, 16, 17, and 19)
which is used for carrying the revolving shuttle box. These catches are
also so formed at I, I, (see Fig. 19,) that the T head or presser J" cannot
be drawn downwards without opening them out quite clear of the
projections of the star wheel J" when it revolves. The spring J" is
attached to both the catches J and J", therefore every time the shuttle
box is about to be changed to any other compartment the T head or
presser J is first drawn downwards from the star weel J", as described
above in the fifth improvement, and opens out the catches J*s and J" at
the same time. The operation of changing the shuttle box is so arranged
by the tappet J that whether the box is made to revolve the distance of
one, two, or three compartments it is completed exactly in the same
space of time, and in the same position of the other parts or movements
of the loom, therefore the T head or presser being released from the
catch Jo which draws it downwards (just before the partial revolution
of the shuttle box is completed) it is pressed upwards by the spring on
its shank, as shewn at Figs. 17 and 19, against the star wheel J", and at
the same time allows the two catches J and J to be drawn together by
the spring J" just in time to catch under the proper projections of the
star wheel Ja, whether the shuttle box has been turned the distance of
one, two, or three compartments, thus absolutely preventing the
revolving box being made to revolve too far, yet allowing the rack bar J"
to take it quite to its proper position however slow the loom is running,
and this in either direction.

page_text: Seventhly. The improved arrangement for preventing the shuttle boxes
being changed from one compartment to another after the weft is broken
in any compartment to which the shuttle may have been sent is as
follows, viz.:-Fig. 22 is an end elevation, and Fig. 23 is a front elevation
of the arrangement. J (Fig. 22) is a stand and grate for steadying the
levers J, 33, 34, 35, and 36, and the rod J", and is fixed to the framing
of the loom 11; J" (Figs. 12, 22, and 23) is a small iron rod connected
to the break J, Fig. 12; J" (Figs. 12, 22, and 23) is a catch for turning
the card cylinder J, and is jointed on a stud fixed on the lever JB,
Figs. 12, 22, and 23, and the end R of the catch J rests on the top of
the rod J. Fixed on the rod J", Figs. 22 and 23, is a projecting finger P
in such position that when the break J, Fig. 12, is thrown on to the fly
wheel the end of the rod J" will first lift the catch J (Fig. 22) by
means of the finger R clear of the catch wheel of the card cylinder J*,
and then the pin P will lift all the levers J, 33, 34, 35 and 36 clear of
the cards J (Fig. 12) so that when any one of the weft threads is broken
and the weft forks stop the loom the break J" being pressed upwards
against the break wheel in the usual way the rod J" not only stops the
card motion by throwing off the catch J" instantly, but if any holes for
changing the box be in the card then uppermost the levers J, 33, 34,
35, and 36, being raised at the same time by the finger P are prevented
from operating upon any of the catches J 7, 8, 9, 10, or 11, and con-
sequently the revolving box cannot be changed although the loom may
continue to run the distance of one or two picks after the weft fork bas
acted when the weft is broken, and this prevents the weaver having so
much trouble in seeking the shuttle in which the weft thread is broken
or any disarrangement in the shuttle boxes.
Having thus described the nature of our said Invention and shewn by
Drawings how the same is or may be performed or carried into practice,
we would have it understood that there are many parts of the mechanism
of looms which we have had occasion to shew in these Drawings to
illustrate our improvements which are old and not of our Invention, also
that we do not confine ourselves to the precise details of combination,
construction, or arrangements shewn; but what we do claim as of our
Invention is,

page_text: as to act direct upon the knocking-off lever or handle by the action of
the slayboard.
Secondly. The method of obtaining a dwell of the slayboard at the
time of picking the shuttles by the use of eccentric wheels, and the
obtaining of a quick stoppage of the loom by the driving pullies and
break pulley being arranged to run at much quicker speed than the
crank shaft.
Thirdly. The method of placing picking cones in and out of position
for contact with the noses of the picking tappets, as shewn and described.
Fourthly. The method of removing the weft threads out of the way
of the action of the weft forks in the manner substantially as described.
Fifthly. The application and use of a double rack bar or two single
rack bars capable of being placed in and out of gear with a spur pinion
on or in connection with the axis of a revolving shuttle box, also the
means by which the same are placed in and out of gear, and the general
arrangement of mechanism for operating revolving shuttle boxes so as
to skip from one compartment to any other in the series, substantially as
shewn and described.
Sixthly. The method of locking or arresting the momentum of
revolving shuttle boxes when skipping any number of compartments,
substantially in the manner shewn and described.
Seventhly. The application of a finger to the ordinary rod used for
lifting the catch off the card cylinder to prevent the shuttle boxes being
changed after the weft is broken, as shewn and described.
In witness whereof, we, the said Richard Longden Hattersley and
James Hill have hereunto set our hands and seal, this Ninth
