PROVISIONAL SPECIFICATION.
Improvements in Change-box and Jacquard Mechanisms of Looms.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York,
Machine Maker, and SIMEON JACKSON of the same place, Mechanic, do hereby
declare the nature of this invention to be as follows, that is to say :-
It relates firstly to improvements in change-box mechanism applicable for use
in the production of bordered fabrics as handkerchiefs or the like, and consists
of arranging and constructing the 'parts forming this mechanism in such a
manner that the number of the pattern surface cards or the length of pattern
surface required for the production of a given design is thereby diminished
while the mechanism is simpler and is rendered less liable to derangement than are
those of said change-box mechanisms as heretofore constructed and arranged.
To attain this object we make use of the well known principle of primary and
supplementary pattern surface mechanism, wherein the pattern-surface_on, one
pattern cylinder controls the movements of the other pattern cylinder. However
instead of making use of a third pattern surface and instead of making use of the
elaborate arrangement of mechanism and parts for securing the proper position
of the shuttle box relatively with its pattern surface so that the one shall always
be in concert with the other, we make use of means whereby when any change
in the meaning of the pattern surface of the primary cylinder is desired, it is
effected by the pattern surface on the supplementary cylinder merely altering
the positions of certain parts mounted upon the feeling levers operating in con-
nection with the said primary cylinder, so that the meaning of the pattern
surface on said primary cylinder is thereby caused to be at one time opposite
to what it is at another time, in other words, any indication on the primary
pattern surface that would at one time cause the shuttle-box to move in one
direction will on this change being effected, cause it to move in the opposite.
direction.
To effect this change on the feeling levers, instead of said feeling-levers being
made to directly regulate the position of the catches through which motion is
imparted to the shuttle box, we mount intervening levers that we arrange to be
operated by projecting pins on the feeling levers so that as these pins are allowed
to press upon these intervening levers so are the positions of these levers
determined.
These projecting pins are attached to or formed on the parts mounted upon
the feeling-levers which are operated by the supplementary cylinder sliding thereon
so that at one time each one of these pins will move one intervening lever when
permitted by the pattern surface while at the other time it will when so permitted
move the other intervening lever.
Suitable intervening levers and parts are arranged to operate in connection with
the supplementary pattern cylinder in order that the pattern surface thereon may
move the pins on the feeling-levers as above described.
By the pattern surface on the supplementary cylinder being made to throw both
of the operating catches through which the primary cylinder receives its motion,

page_text: out of gear whenever a reversion in the direction of motion of this primary
cylinder has to be effected such reversion may be effected while the loom runs
to throw in two picks or shots of weft and not four picks as has heretofore been the
case.
The supplementary pattern surface is made to effect this disengagement of both
of the cylinder's operating catches by causing their operating lever to move only
half the distance at this time, while by it being turned another stage further it
causes this lever to throw one catch out of gear while it allows the other to fall into
gear, and these catches are so joined together by suitable connecting rod mechanism
as to allow this movement to be effected.
These operating catches are also coupled together in such a
manner that
on the breakage or failing of the weft they are thrown out of gear so that the
motion of the pattern cylinder is thereby arrested at the proper time as is well
understood.
The second part of our invention relates to improvements in the take-up
mechanism and consists of arranging and constructing this mechanism in such a
manner that on a reversion in the direction of motion of the pattern surface con-
trolling the movements of the heddle operating mechanism, a like reversion in
the direction of motion of the fabric's take-up beam is effected and that with
precision.
$
To effect this object we couple the pattern cylinder in the heddle operating
mechanism directly to and with the take-up roller and to effect this coupling we
mount upon the crown wheel (through and by which rotary motion is imparted to
the pattern cylinder) a bevel wheel so that as the said crown wheel is rotated so
also is this bevel wheel rotated.
This bevel wheel is made to gear with another wheel mounted upon a shaft which
by other gearing wheels imparts motion to another shaft upon which is mounted a
worm gearing with a wheel on the ordinary stud upon which the usual catch wheel
in the take-up mechanism is in an ordinary way mounted.
The third part of our invention relates to improvements in jacquard mechanism
and consists of mounting and arranging means to operate in connection with the
pattern cylinder of this mechanism so that at any time when this said pattern
cylinder has to be rotated backwards or has its rotary motion reversed to bring
certain of its pattern cards again into action for allowing corrections of any
irregularities that may have been caused in the weaving of the fabric in the loom,
the pattern mechanism for controlling the movements of the shuttle-boxes may
also have its rotary motion reversed and moved in unison therewith so that at all
times these said pattern surfaces are thus enabled to maintain their respective
relative positions.
We accomplish our purpose by mounting the well known arrangement of wheels
upon the moveable framework carrying the jacquard's pattern cylinder, these
wheels together with the other usual parts being employed for imparting inter-
mittent rotary motion to said pattern cylinder from one of the loom's motor shafts,
while the pattern cylinder of the box operating mechanism is also operated from a
motor shaft of the loom.
The gearing wheels and shafts by and through which the motion from the loom's
shaft is imparted to the jacquard's pattern cylinder are arranged by a suitable
clutch coupling so that they may be manually coupled to a shaft that is geared
with the rotary cylinder of the box mechanism, by which means when these shafts
are thus coupled, on the jacquard cylinder being manually, by an appropriate
winch handle arrangement, rotated in its backward direction so also will that of the
box mechanism.

We, RICHARD LONGDEN HATTERSLEY, of Keighley, in the County of York,
Machine Maker, and SIMEON JACKSON of the same place, Mechanic 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 :-
This invention relates firstly to improvements in change-box mechanism applicable
for use in the production of bordered fabrics such as handkerchiefs and the like, and
consists of arranging and constructing the parts forming this mechanism, in such a
manner that the number of pattern surface cards, or the length of pattern surface
required for the production of a given design is thereby diminished, while the
mechanism is simpler, and is rendered less liable to disarrangement than are those
of said change-box mechanism as heretofore constructed and arranged.
In order to clearly demonstrate our invention, we append hereto sheets of
drawings marked with letters of reference, Figures one to five inclusive illustrating
the first portion of our invention.
Figure 1 is an end view of a loom with our improvements fitted thereto,
Figure 2 is a plan of the mechanism without the pattern card cylinders showing
the indicating levers,
Figure 3 is an end view without the primary card cylinder, and
Figures 4 and 5 are enlarged views of the operating catches, Figure 4 being a
side view and Figure 5 a plan of same.
To attain the object before stated, we employ a primary pattern cylinder A of
which the pattern surface consisting of blanks and holes regulates or controls
indicating levers or feelers B, and C, in the well known manner, and which also
controls an additional indicating lever D which operated by means of the box
lever E and E. Intermittent rotary motion in either direction is imparted to the
cylinder A by means of catches F and F and ratchet wheel attached to the said
cylinder, as the lever B to which the catches F and F are pivotted is raised by
the eccentric G and gridded lifter H in the well known manner, the direction in
which the cylinder A is revolved or whether at certain predetermined times
it remains stationary, being regulated by means of the pattern surface of a
supplementary cylinder J as hereinafter described. To the lever D we attach a
ratchet D' for the purpose of intermittently revolving the supplementary cylinder J
as a hole or blank is presented on the pattern surface of the primary cylinder A, in
the event of a hole being presented the lever D drops a greater distance than when
a blank is presented, thereby permitting the ratchet D to take hold of a tooth of
the ratchet wheel attached to the supplementary pattern cylinder J. The pattern
surface in connection with this supplementary cylinder consists of pins and blanks
which operate and control the levers K and K¹. The lever K is operated for the
purpose of regulating the catches F and F so as to determine the action of the
primary cylinder A, which is effected by mechanism consisting of rod L and
lever M operating the pin N, attached to the latter, to and fro in a horizontal
direction. As illustrated in Figure 1 the pin N is in its forward position, and the
catch F is in contact with the ratchet wheel of the primary cylinder A, which said
cylinder will therefore be revolved as the lever B is raised by the gridded lifter H
in the direction of the arrow, the contrary motion of the cylinder being effected
when the catch F is in gear with its ratchet wheel which is effected as follows!
The catches F and F are joined together by connecting mechanism so that they
act in unison, that is as the catch F is put into gear with ratchet wheel the catch F¹
passes out of gear and vice versa, such mechanism being shown in Figures 4 and 5.

page_text: The catches are elongated beyond the centres on which they are pivotted to the
lever B, and thus formed into levers of the first order, a rod. F joining them
together at the weight end, this said rod being slotted for purpose hereinafter
described.
On the presentation of a pin on the pattern card of the cylinder J, the pin N is
caused to travel from right to left, and at the same time springs attached to the
catches F and F are put into tension, and on the presentation of a blank the pin N
travels in the opposite direction, whereby the said springs are enabled to reverse
the catches, drawing F out of gear and F¹ into gear with the ratchet wheel. The
supplementary pattern cylinder J is also capable of effecting a complete stoppage
of the revolution of the primary cylinder A in either direction, such stoppage being
effected by the presentation of a somewhat shorter pin on the pattern surface of the
first named cylinder. which causes the pin N to assume a inid position, so that
neither of the catches F and F is in contact with the ratchet wheel of the primary
cylinder, by which means when a reversion in the direction of the motion of the
primary cylinder has to be effected, such reversion may be effected while the loom
runs to throw in two picks of weft and not four, as heretofore has been the case.
The indicating levers or feclers B and C do not directly regulate the position of
the catches whereby motion is imparted to the shuttle box, and to such levers we
attach pins b, b, and c, which operate upon the levers P and P. The pins b, b', & c
are mounted or fixed to blocks Q and Q¹ which said blocks are capable of being
moved backwards or forwards in horizontal slides formed in the indicating levers B
and C, and for this purpose we employ the lever K', operated upon by the pattern
surface of the supplementary cylinder J, which said lever is coupled to the
blocks Q&Q by suitable coupling rod and levers. This arrangement is for the
purpose of reversing with the pattern cylinder A the action of the indicating
levers B and C, so that the indicating lever which was at one time causing the
shuttle box to be actuated in one direction may at another time cause the shuttle
'box to be actuated in the opposite direction. By reference to the drawings, it will
be seen that pins b and bare attached to and working in conjunction with the
indicating lever B, and that pin c is attached to and working in conjunction with
the lever C, pins b and c being shown in operation upon the levers P and P
respectively, while the pin b¹ is out of contact with either of the said levers 'P
and P. The alteration in the action of the indicating levers B and C upon the
mechanism connected with the rotation of the shuttle box, is effected as the position
of the said pins relatively to the levers P and P' may be changed by the pattern
surface of the supplementary cylinder J, the presentation of a blank thereon
causing the lever 'K' with its connections to slide the blocks Q and Q₁ so that the
pin b is removed out of contact with the lever P, and at the same time the pin bl
is brought into such a position that it controls the movement of the lever P¹, while
the pin.c which was previously in contact with the lever P¹ is made to control the
movement of the lever P, the reverse action taking place at such times as a pin
may be presented on the pattern surface of said supplementary cylinder and, the
pins 6, 6, and c are brought to the position as illustrated. In order that the action
of the primary cylinder Å may be arrested at such times as the weft may be broken
or fail, connection is made between the stop motion and the catches F and F¹, whereby
oue or the other of the said catches, as the case may be, is taken out of gear with
the ratchet wheel of such primary cylinder, which we effect by attaching to the
stop mechanism a rod R which is lifted as the weft breaks or fails by the well
known means, whereby one or the other of the catches For F is moved out of
gear with the ratchet of the primary cylinder by the action of the rod R upon
the levers S or S', which connect the catches F and F such movement of the
catches F and F¹ being permitted by reason of the slot in rod F'.
The second part of our invention relates to improvements in jacquard mechanism and
consists of mounting and arranging means to operate in connection with the pattern
cylinder of this mechanism so that at any time when this said pattern cylinder has to
be rotated backwards has its, rotary motion reversed to bring certain of its pattern

page_text: cards again into action, for allowing corrections of any irregularities, that may have
been caused in the weaving of the fabric in the loom, the pattern mechanism for
controlling the movements of the shuttle boxes may also have its rotary motion
reversed and moved in unison therewith, so that at all times these said pattern
surfaces are thus enabled to maintain their respective relative positions 'These
improvements are shown in Figures 6 and 7, Figure 6 being a front view and
Figure 7 a side view of our improvements. We attain our object by attaching to
the looms motor shaft a bevel wheel A gearing with another bevel wheel A¹
attached to au upright shaft B by means of a clutch box B', from which motion is
taken by bevel wheels C and C¹ to drive a 'shaft to which is fixed the ordinary
"shogger" wheel D for driving the pattern cylinder of the box operating mechanism.
The upright shaft B also carries another bevel wheel E gearing with the bevel
wheel E' driving a horizontal shaft F to the opposite end of which is fixed another
bevel wheel F¹ for actuating the well known arrangement of wheels employed for
imparting intermittent rotary motion to the jacquard pattern cylinder. The clutch
box B may be lifted out of gear by means of a lever G, and the upright shaft B
thereby uncoupled from the motor shaft which said lever at the same time by
means of supplementary levers relieves the card cylinder from the weight of the
indicating levers. To the horizontal shaft F we attach a handle H whereby when
by means of the clutch box B¹ the shaft B is uncoupled from the motor shaft, the
jacquard cylinder may be manually rotated backwards simultaneously with the
pattern cylinder of the box operating mechanism.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is
1. The combination of a primary pattern cylinder with a supplementary pattern
cylinder and their respective mechanisms, such supplementary pattern cylinder
receiving its motion from the primary cylinder, which said primary cylinder is in
turn governed and controlled and made to revolve in either direction by the pattern
surface of such supplementary cylinder substantially in the manner as shown and
described and for the purpose herein set forth.
2. In combination with a reversible primary pattern cylinder, a supplementary
pattern cylinder receiving its motion from the primary cylinder, and indicating
levers or feelers, and their respective mechanisms whereby the action of such
indicating levers or feelers on the loom's shuttle boxes is reversed by the pattern
surface of such supplementary cylinder, substantially in the manner as shown and
described, and for the purpose herein set forth.
3. In combination with a reversible primary pattern cylinder, catches or levers
operated upon by the looms stop motion, whereby the revolution of such pattern
cylinder is arrested simultaneously with the breakage or absence of the weft,
substantially in the manner as shown and described, and for the purpose herein set
forth.
4. The arrangement and combination of parts whereby the jacquard pattern
cylinder may be manually reversed, simultaneously with the pattern cylinder
controlling the shuttle box mechanism, substantially in the manner shown and
described, and for the purpose herein set forth.
