PROVISIONAL SPECIFICATION.
Improvements in Pattern Mechanism for Controlling the Movements
of Shuttle Boxes used in Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in
the County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in pattern mechanism for controlling the move-
ments of shuttle boxes used in looms for weaving, relates to certain additions and
modifications to an invention numbered 18267, 1890, and consists, firstly, of
additional mechanism whereby the shuttle box may be operated every two picks
instead of four, even on a change card, which we effect by supplementarily
controlling the action of the indicating levers or feelers by means of a tumbler
lever, oscillated by a pin or stud attached to the horizontal rod which regulates the
catches in connection with the ratchets for revolving the card cylinder, and such
other pins or studs attached to the said indicating levers or feelers as may be
necessary to work upon the oscillating tumbler lever.
The second part of our invention relates to improvements and modifications of
the pattern mechanism described in the above named Specification, our object being
to simplify such mechanism, and at the same time to more effectually control the
action of the shuttle boxes.
Our improvements are carried into effect as follows, that is to say, on the end of
the usual pattern cylinder, we fix a cylinder or disc prepared with pegs or cards,
which controls the action of a lever, this latter by means of ratchet and wheel
mechanism causing to be revolved at predeterminated times the auxiliary cylinder
fitted with pegs or cards. The pegs or cards of this auxiliary cylinder, of which
there may be several parallel rows, operate on one or more cranked locking levers
as a peg or blank is presented, the number of such levers being determined by the
number of rows of pegs on the cylinder, these said locking levers being for the
purpose of locking or causing to be inoperative the indicating levers of which there
be a series, each locking lever controlling one or more indicating levers as
desired. The indicating levers are raised by the ordinary gridded lifter, as is also
the lever and ratchet for revolving the auxiliary cylinder.
may
In operation each of the indicating levers is governed by its respective row of
pegs or blanks on the pattern cylinder, but the indicating levers can operate the
shuttle box, through teller levers and well known mechanism, only when released by
the corresponding locking lever, whose action is governed by the presentation of a
peg or blank on the auxiliary cylinder.

Improvements in Pattern Mechanism for Controlling the Movements
of Shuttle Boxes used in Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in
the County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, 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 for improvements in pattern mechanism for controlling the move-

page_text: ments of shuttle boxes used in looms for weaving, relates to certain additions and
modifications in an invention numbered 18267 of 1890, and consists of devices and
combination of devices herein set forth and described, and illustrated by the
accompanying sheets of drawings, in which the different parts are denoted by letters
or numerals.
The first part of our invention, which is illustrated by Figs. 1 and 2, of such
drawings, consists of additional mechanism whereby the shuttle box may be
operated every two picks instead of four, even on a change card, which we effect
by supplementarily controlling the action of the indicating levers or feelers, by
means of a tumbler lever, oscillated by a stud attached to the horizontal rod which
regulates the catches in connection with the ratchets for revolving the card
cylinders, and such other pins or studs attached to the said indicating levers or
feelers as may be necessary to work upon the oscillating tumbler lever.
Fig. 1, is a side view of the parts necessary to explain the above improvements,
and
Fig. 2, is a plan of same.
In order to more easily identify the relation these additional parts bear to the
parts described and illustrated in the before named Specification, we use, in this
description, the same letters of reference used in the prior Specification, for those
parts which are common to both, but apply numerals to designate the parts which
are added to effect our improvements.
T,
Referring to the drawings, the letters b, c, b', and c', are the indicating levers or
feelers, which are operated upon by the pattern surface or cards carried by the
intermittently revolved cylinders a and a¹. k and are the additional levers
operated upon by the card surfaces d and d', for actuating the supplementary
cylinder m, by means of which cylinder horizontal motion is imparted to the rod
and one or the other of the card cylinders a and a', is caused to revolve as the
gridded lifter raises the lever b. u and are the projecting fingers attached to the
indicating levers b, c, b', and c', which operate upon the teller levers t and t¹, thereby
putting other parts into and out of operation in the well known manner, for effecting
the movement or changes in position of the shuttle boxes.
To the frame of the loom we fix a stud 1, on which we pivot a tumbler lever 2,
prepared at its lower end to engage with a pin 3 fixed to the horizontally moved
rod r. The upper end of the tumbler lever 2 is bent to a right angle, and is carried
underneath all the indicating levers b, c, b', and c', and the horizontal part of said
lever is cranked as shown by plan view (see Fig. 2).
To the indicating levers b, c, b', and c¹, we fix projecting pins 4, in such a position
that two of these pins rest upon the horizontal portion of the lever 2, which must
be either the pins connected to the levers b and c, or the pins connected to the
levers b' and c¹, to effect which purpose the tumbler lever 2 is cranked as before
mentioned.
Only one set of indicating levers controls the action of the shuttle box at one
time, either the levers b and c, or the levers and c¹ are operating on the teller
levers and t¹, according as the horizontal rod r is moved by the action of the
supplementary cylinder, and each set of indicating levers, controlled by their
respective card cylinders, operate upon the shuttle box to produce different
designs, but prior to the application of the tumbler lever 2, and other parts working
in conjunction therewith, a change from one set of levers to the other could only be
effected while the loom had "picked" four times, as during the time the supple-
mentary cylinder has moved the rod "+ so as to effect a change in the rotation of
the cylinders a and a', the shuttle has thrown in two picks of weft, and before the
other set of levers, controlled by the cylinder which has been put into gear, can
operate on the shuttle box, it is necessary that such cylinder should be revolved,
which also can only be effected during the time the shuttle has thrown in another
two picks.
"
By the action of the tumbler lever 2, and the pins 4 attached to the indicating levers,
immediately the rod r is moved to effect a change in the rotation of the cylinders a

page_text: and a', the set of levers, which immediately before were operating upon the teller
levers, are propped up by the pins 4 resting on the tumbler lever 2, and are
rendered inoperative, while the other set of indicating levers is free to be controlled
by the card surface of its cylinder, whereby it will be easily understood that the
shuttle box may be operated every two picks instead of four on a change card.
Figs. 3, 4, and 5, illustrate the second part of our invention, consisting of a
modification of the arrangement, and formation of the parts constituting the pattern
mechanism, for controlling the movements of shuttle boxes mentioned in the before
named Specification, whereby not only is the number of pattern cards forming the
pattern surface greatly reduced, as compared with the number for producing the
same design or effect under ordinary circumstances, but such mechanism is
materially simplified, and at the same time the action of the shuttle boxes is more
effectually controlled than has heretofore been the case.
Fig. 3, illustrates in side elevation our improved mechanism for effecting the
above purpose, and
Fig. 4, is a plan view of same.
The figures are marked with letters of reference, in which A indicates the
primary pattern cylinder, to which is attached a ratchet wheel B, operated upon
by a swing catch C, pivotted to a lever D. The lever D is actuated by the gridded
lifter E, whereby intermittent rotary motion is imparted to the cylinder A. In
addition to the peg or card surface for operating a series of indicating levers F, as
hereafter described, the cylinder A is provided with additional surface, (or a small
additional cylinder or disc may be mounted on the same shaft, and secured to aud
revolved with the said cylinder A), for receiving and carrying pegs or lagging.
By means of this additional peg surface, a supplementary cylinder G is caused to
rotate at predetermined times, and for this purpose we attach to the lever Da
catch H, which engages with pins, or a ratchet wheel attached to the cylinder G.
It will be easily understood that the presentation of a blank to the end of the
lever D, by the peg surface or lagging, causes the said lever to fall a greater
distance than when a peg is presented thereto, whereby the catch H is raised, and
is enabled to take hold of a pin, or tooth of a ratchet wheel attached to the
cylinder G, and at the next operation of the gridded lifter E, the cylinder G'is
revolved a certain distance.
The supplementary cylinder G is provided, similarly to the primary cylinder A,
with lagging holding a series of parallel rows of pegs, which operate upon a like
number of parallel locking levers 1, there being eight shown in the drawings (see
Fig. 4), although the number might be either more or less as desired. Each of
these locking levers I controls one or more indicating levers F, of which there are
a like number of sets, that is, the locking levers I regulate which set of the
indicating levers F is to be operated upon by the pattern surface of the cylinder A,
and moved by the gridded lifter E, in the following manner. The locking levers [
are shaped after the fashion of bell crank levers, and are fulcrumed on a shaft K,
while the indicating levers are fulcrumed on a shaft L, both of which shafts are
supported by the framework of the loom.
"
The levers I are formed with notches at their lower extremities, or otherwise
prepared to receive the ends of the indicating levers, the locking levers being of
such a breadth that they support or lock three levers, two of which are indicating
levers, and the third a lever M, for operating upon the "cram or setting up
motion. The indicating levers F, and the " cram ("levers M, are fulcrumed at
such a point that they are unequally balanced, their heaviest ends being the ones
which are operated upon by the pattern surface of the primary cylinder A, which
causes their other ends to bear against the locking levers I, and when any one set
is released by its corresponding locking lever through the operation of the
cylinder G the heavier ends fall, and may be operated upon by the pattern surface
of the cylinder A, and also operate upon the teller levers N and N', projecting
pieces and f being cast with said levers for this purpose. The locking levers I
only permit one set of indicating levers to be in operation at one time, as the pegs

page_text: of the lagging of the supplementary cylinder G are arranged consecutively, that is,
as a peg on one line of the lagging is brought into action upon its respective
locking lever by the revolution of the supplementary cylinder, the peg on another
line of the lagging which was immediately before acting on its respective..locking
lever, is taken out of action.
Having described how the action of an additional lagging surface on the primary
cylinder A effects a revolution of a supplementary cylinder C, which by several
rows or parallel lines of lagging operates on a number of locking levers I, whereby
corresponding sets of indicating levers F are freed so as to be operated upon by
the lagging rurface of the primary cylinder A, such lagging being arranged in
parallel lines or a line for each lever, and how such levers when freed operate
upon teller levers N and N1, for the purpose of putting into and out of gear
other parts for effecting the changes and movements of the shuttle box in the well
known manner, we will explain how the combination of these parts is applied in
actual weaving.
Each set of indicating levers represents a different part of the pattern or design
which it is required to produce, and by this arrangement of indicating levers
controlled by locking levers, we are enabled to very materially reduce the length.
of the pattern surface for producing. a given design. Suppose the design to consist
of eight parts, then, the shuttle box mechanism for producing these eight different
parts will be controlled by one set of indicating levers for each part, thus, part
one will be produced by the action of the first set of indicating levers, part two
by the second set, and so on. Each set of indicating levers being provided with
its corresponding locking lever, we number these levers from one to eight inclusive,
commencing from the top of the drawing (see Fig. 4). In weaving part one of
our design, the indicating levers to produce this part will have been released by
the operation of a peg on the locking lever 1, and this part of the design will be
produced until such time as the supplementary cylinder is revolved, when the peg
supporting lever one is removed, and by the presentation of another peg to lever 2,
this latter lever is moved, thus effecting the locking of the indicating levers for
producing part one of the design, but giving freedom to the next set of indicating
levers, whereby the shuttle box mechanism is operated upon, to produce the second.
part of the design. In order to produce the third part of the design, locking
lever 2 is operated upon to lock its corresponding indicating levers, and locking
lever 3, is operated to unlock its corresponding indicating levers, and so on,
until all the eight parts of our design are completed, when the operations are
repeated.

In conjunction with each set of indicating levers we mount the additional or
levers M, which are free to operate only when released by the corre-
sponding locking levers. These " cram levers are somewhat longer than the
indicating levers, and are for the purpose of operating upon the "cram or.
setting-up mechanism, and each set of indicating levers F is provided with a cram
lever M so that the "setting-up" of the fabric may be effected during the
production of any part of the design. The pattern surface of the cylinder A is
