Improvements in Pattern Mechanism for Controlling the Movements
of Shuttle-boxes, and in Stop-motions of Looms.
We, THOMAS STUTTARD, JOHN HARTLEY and JONATHAN WHITEOAK of
Vale Street Mill, Nelson, in the County of Lancaster, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The first part of our invention is designed for the reduction of the length of the
pattern surfaces now used in controlling the action of rotary shuttle boxes. For
this purpose, we employ in addition to the ordinary feelers or indicating levers, two
other feelers having separate indications on the same set of cards or pattern
surfaces, as the rest of the feelers. To the opposite ends of the additional levers
are attached vertical hooks or catches which are capable of engaging with the teeth
of a ratchet or other suitable wheel fixed to a barrel provided with a surface of
peg-lags or lattices which are designed to act in conjunction with the card surfaces
in determining or controlling the movement of rotary shuttle boxes.
The pegs upon the lattices are preferably arranged to follow each other in single
file and act upon a feeler connected to the horizontal arm of a shaped lever the
vertical arms of which are respectively connected one to each catch or actuating
medium of the card cylinders, in such a manner, that when a peg is presented to
the said feeler, one of the actuating catches of the card cylinders is lifted and then
becomes inoperative; whilst a blank when presented, (on the lattice) to the said
feeler drops the lifted catch and withdraws the catch from the other card cylinder.
The second part of our invention relates to loose reed looms, and consists of
mproved means for applying the weft brake each time the reed is thrown out of
place. For this purpose, when the reed is out of place, the ordinary stop-rod finger
smade to strike a spring-bracket to release a spring arm or finger, so as to with-
raw the fork lever (with which it is connected) and apply the weft brake
imultaneously with the liberation of the setting on handle from its detent.

Improvements in Pattern Mechanism for Controlling the Movements
of Shuttle-boxes, and in Stop-motions of Loo:ns.
We THOMAS STUTTARD, JOHN HARTLEY and JONATHAN WHITEOAK of
Vale Street Mill, Nelson, in the County of Lancaster, Manufacturers, 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, that is to say :-
The first part of our invention consists of an improved arrangement and
formation of parts constituting the pattern mechanism for controlling the movements
of shuttle-boxes whereby the number of pattern cards forming the pattern surfaces
is greatly reduced as compared with the number required for producing the same
design or effect under ordinary circumstances, and the second part of our invention
relates to loose reed looms wherein several shuttles are employed and consists of
the application to these looms of means whereby the motor parts of the pattern
cylinders are disengaged and the other motions of said looms are more abruptly
Price 11d.1

page_text: arrested on the displacement of the reed than they have been heretofore so that
the damages to the work being executed incident to what are known as "two
shuttle traps" or the results from the loom continuing its motion after one or more
shuttles have been stopped in their passage through the warp, are entirely
avoided.
In the accompanying sheets of drawings which are illustrative of this invention,
Fig. is an end view of a portion of a loom with our improvements applied, the
pattern cylinder a being shewn in section in order that other parts might be more
clearly seen.
Fig. 2 is a similar view to Fig. 1 but only shews certain of the motor parts,
while the framework and the other motor parts are omitted.
Fig. 3 is a top view of parts beneath the line A B of Fig. 1 and
Fig. 4 is a similar view of the parts above this line.
Fig. 5 is a front view of parts shewn by Fig. 1.
Figs. 6 and 7 are end and top views of a portion of a loom shewing our improved
stop-motion while
Figs. 8 and 8 are similar views to Figs. 6 and 7 but shew a modified form of
this part of our invention.
To attain the object of the first part of our invention we employ in addition to
the ordinary feelers or indicating levers b and c, two other feelers and e¹ which
are separately indicated upon by the additional pattern surfaces or cards d' the
cards d, being employed for operating or indicating upon the levers b and c.
Intermittent rotary motion is imparted to the cylinder a by the ratchet e as the
lever b, to which it is hinged, is being raised (by the eccentric f operating the
gridded lifter in the well known manner) provided this ratchet e is not held out
of gear with its wheel has is hereinafter described, and a like motion in like manner
is imparted to the cylinder a' by the ratchet e and wheel has the said lever is
raised (the said wheel being mounted on a sleeve or boss which is formed on the
cylinder a and made to extend through the cylinder a in such a manner that said
cylinder a may rotate upon it). The cards d and d' are also respectively employed
for operating the levers and on which are mounted the ratchets and
respectively, these ratchets and being employed for operating the cylinder m by
means of the ratchet wheel m³ as and when they are enabled or permitted by the
pattern surfaces d and d¹.
The pattern surface (which consists of pins n' inserted into or mounted upon the
cards n to produce results necessary for the weaving of the design desired) ou
the cylinder m, operates the lever o so that by the rod p and the lever 7 the rod
is made to hold its projecting pieces s and s¹ in such positions that only one or the
other of the ratchets e and e¹ is allowed to be in operating contact with its
respective wheel or as the case may be, that is to say, when the rod is in its
forward position as shewn by Fig. 2 its piece s is so far clear of the ratchet e¹ that
this ratchet by gravity falls into operating contact with its wheel while the
piece holds the ratchet e from contact with its ratchet h; on the other hand
when the rod is caused to recede its piece s is brought against the ratchet e¹ and
so holds it out of operation while the piece s will then be moved clear and on to the
other side of the ratchet e allowing this to fall into contact with its wheel h.
Both the sets of levers b c and care enabled and made to operate the levers t
and which put the other parts into and out of operation in the well known manner
for effecting the movements or changes in position of the shuttle boxes as is well
understood, and to prepare the levers t and t¹ so that they may be thus operated,
projecting fingers u and u¹ are fixed to them and made to project beneath the said
levers bc and be the downwardly extending pins on which operate them as will
be seen.
The operations of the foregoing parts are as follows:-Supposing that the lever o
is in its highest position as shewn by Fig. 2, the rod r is then in its forward position
so that its projecting piece s will allow the ratchet e' to engage with its wheel /'

page_text: while its piece s' is so far forward as to guide the ratchet e from laying hold of the
wheel hence the cylinder a will be in operation and the cylinder a will be
stationary, and since both the pattern surfaces d and have equal control over the
movements of the shuttle-box any design carried by the pattern surface & will now
5 be in course of production until by such of its said pattern surface (as openings in
the cards) being brought successively into position as is necessary to cause the
lever to rotate the cylinder m so that the pin n' is brought from being beneath
the lever o for changing the positions of the ratchets e and e¹ the cylinder a' is
thrown out of operation at which time the cylinder a is put into operation and will
Oso continue until by its pattern surface d it has, by its lever k and ratchet 1, moved
the cylinder m so that one or other of the pins n' is again beneath the lever
this it will be seen that the design carried by either of the pattern surfaces d or d
0, from
may be reproduced as often as may be desired and arranged for on the pattern
surface n and this is effected by the employment of only as many pattern cards n as
are necessary for each reproduction so that when one or the other part in the piece
being woven, (which part may in itself be only a short design) has to be reproduced
a large number of times instead of requiring as many cards in the pattern surface
as would represent each pick or two picks of weft in the whole of said pattern or
design only comparatively few of them are now necessary.
By the employment of the arrangement of parts hereinbefore described, the two
cylinders a and a' are worked in such unison with the other parts of the loom as
not to interfere with the use of any of the common and well-known arrangements
of box operating mechanisms as at present in use, since their direction of motion
for producing the object desired is exactly the same as is that of the common
cylinder.
The object of the second part of our invention is attained by making the ordinary
stop-rod finger v to strike (on the displacement of the reed) against the bracket w
which is now mounted upon the spring w' instead of upon the handle lever as in the
ordinary way. By this striking of the bracket w the spring w¹ is moved to release
the arm of the lever which is drawn or operated by the spring y in such a
manner that its arm a² operates the fork lever (by being joined thereto by the
rod ³) drawing same as does the weft lever on the failing or breakage of the weft
(its operations being well understood), so that the usual mechanism is released for
putting the brake y² into operation simultaneously with the liberation of the setting-
on-handle for the purpose of shipping the belt from the fast to the loose pulley, as
also with the operation of the parts for disengaging the mechanism for rotating the
pattern cylinder, this mechanism being joined to and operated with the brake
mechanism in the common and well known manner.
This same object may be attained by forming a projecting arm z² on the fork
lever as shewn by Figs. 8 and 84, and arranging the stop-rod finger v to operate
within the loom instead of on the outside of the end frames, in order that it may
strike against said arm z².
Having now particularly described and ascertained the nature of our said
nvention and in what manner the same is to be performed we declare that what
ve claim is:
1. The combination of two separately operating pattern cylinders and their
espective operating levers and mechanisms, with an additional pattern cylinder
eceiving its motion from the pattern surfaces of both the first named pattern
ylinders the movements of which are controlled or governed by this additional
attern cylinder substantially as specified and for the purpose set forth.
2. The combination of the cylinders a and a' with the additional cylinder m
gether with means whereby the pattern surfaces on the cylinders a and a¹ are
abled to control as well as operate the rotary movements of the cylinder m which
turn controls the operations of said cylinders a and a' substantially as specified
d for the purpose described.

page_text: 3. The arrangement and combination of parts whereby the weft brake on a loom
is automatically applied simultaneously with the disengaging of the driving
mechanism thereof on the displacement of the reed substantially as is herein
specified.
