Improvements in Jacquard Apparatus for Weaving or other Textile
Manufacture.
DAVID DALGLISH 26 Hart Street Droylsden near Manchester, and JOHN
EDWARD WADSWORTH 3 Brighton Terrace Moston near Manchester, Sole
Partners of the Firm of Dalglish & Co, Jacquard Machinists Greenside Lane,
Droylsden near Manchester do hereby declare the nature of this invention to be
as follows:-
The improvements relate to Jacquard apparatus and are applicable to jacquards
for weaving or to jacquards in other textile manufacture. The object of the
improvements is to prevent the cards, where two setts are in use (one card of each
sett alternately) from getting crossed, or out of their proper sequence, or in other
jacquards where it is preferred, should they get out of their proper sequence, they
are at once automatically put right again, without stopping the loom, and without
the intervention of the operator.
To attain these objects, in the case of jacquards whose cylinders are oscillated
in battens, we provide an arrangement of levers and catches, by which the
cylinder in the one batten is simultaneously turned round, to bring a fresh card into
operation, when the cylinder in the other batten is turned round, and after these
two cards have actuated the needles, of the jacquard, the two cylinders at the same
moment, each turn over another fresh card, the one cannot turn without the other,
and so in whatsoever order of sequence they may be started, they will continue
therein and the cards cannot cross, nor get out of order.
To allow the operator to move the loom when stopped for any purpose, a
moveable nosepiece is attached to the hauling catch of one of the cylinders, which
prevents this catch from taking effect so soon as it otherwise would, the loom
can by this means, be put a quarter turn backwards, without the cylinders
turning.
In the case of those jacquards, which have no battens, but whose cylinders are
carried in slides we obtain the same result, that is causing the two cylinders, to
turn together, by means of an endless chain, band, or strap, passing around the
cylinders themselves, or around pulleys, plain, or pitched, such pulleys being so
contrived, as that when they are moved, the cylinders are moved also. And
should it not be convenient to adopt any of the above described arrangements, we
prevent the cylinders from being moved at all when the loom is turned back, by
fixing a wheel on the crank or any other shaft in the loom, and by means of a
pawl," which skips over the teeth of the wheel so long as the loom goes
forward," but which drops into the teeth, at the first "backward" motion of the
loom, and by an arrangement of rods, and belleranks, that lift the hauling catches
of the cylinders of the jacquard, clear of the lantern ends thereof, the loom can be
turned backward without the cylinders turning over, and without the cards, getting
out of their proper order of sequence. But should it not be convenient to adopt
any of the forementioned methods for preventing the cylinders and cards getting
wrong, we employ a needle and a hook, either of, or extra to the needles and
st

page_text: hooks of the jacquard, and by an arrangement of having the faces of the cylinder
opposite this needle to be alternately a blank or a hole (or the cards can be used,
and punched so) and by causing this needle to project, through the needle board,
when the blank face of the cylinder should operate, and be withdrawn, when the
face with a hole in it should operate, by this arrangement, when the cards and
cylinders are right there will be no change, because none is required, but should
the cylinders or the cards, get turned, so that the hole in either comes opposite the
needle point, the needle is not pushed back, the hook is not put off the "grife,"
and by a connection between this book, and the hauling catch of this cylinder, the
catch is lifted, and the cylinder is not turned, but comes on again with the same
card, (meanwhile the needle is withdrawn) which makes up for the turn it got,
that put it out of time, and the two cylinders are again in unison. The same
arrangement is applied to the other cylinder.

Improvements in Jacquard Apparatus for Weaving or other Textile
Manufacture.
We, DAVID DALGLISH, and JOHN EDWARD WADSWORTH, of the Firm of
Dalglish and Company, Greenside Lane, Droylesden near Manchester, Jacquard
Machinists, 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 :--
The improvements relate to Jacquard apparatus and are applicable to jacquards
for weaving, or to jacquards in other textile manufacture. The object of the
improvements is to prevent the cards where two sets are in use (one card of each
set alternately) from getting crossed, or out of their proper sequence; whether in
their forward automatic action or in being turned backwards by the operator when
the loom is at rest, as is frequently requisite.
To attain these objects, in the case of jacquards whose cylinders are oscillated
in battens, or slays, we provide an arrangement of levers and catches by which the
cylinder in the one batten is simultaneously turned round to bring a fresh card
into operation when the cylinder in the other batten is turned round, and after
these cards have actuated the needles of the jacquard, the two cylinders at the
same moment each turn over another fresh card; the one cannot turn without
the other, and so in whatsoever order of sequence they may be started,
they will continue therein, and the cards cannot cross nor get out of order.
The accompanying drawings illustrate one form of apparatus for this purpose,
Figs. 1. and 2. being elevations of opposite ends of a jacquard frame provided
with apparatus according to our improvements; and Figs. 3. and 4. views
of a cylinder catch with sliding attachment to be hereinafter described.
In Figs. 1. and 2, the wires, hooks, needles, harness, and other ordinary portions
of a jacquard are omitted for the sake of clearness.
The same letters indicate corresponding parts wherever they occur.
a. a. is the frame of the jacquard.
In Fig. 1. the hand apparatus for turning back the two sets of cards
simultaneously is shewn, and consists of a bell-crank lever b, capable of actuating
the push bar c, by pressure against the pin c', fixed thereto, and of simultaneously
actuating the push bar d, through the connecting link e, which turns upon its
centre e¹.

page_text: As the operator draws down the cord or connection 6', when the loom is stopped
and the cylinder battens g. g¹ are at half-stroke, as shewn in Fig. 1, the bars c. d.
are simultaneously forced against the cylinder "nogs" h¹ k¹ and the cylinders h. k.
are moved back one card. A swell c is formed upon the bar c. and a similar
swell upon the cylinder catch 1, by which means, as the bar c. is moved, the
catch is pushed out of action, and enables the cylinder h. to turn backwards.
Similarly, the catch m, of the opposing cylinder, shewn in its extreme positions in
Fig. 2. may be pushed or kept out of action by the projections k² upon the lantern
end of the cylinder.
To prevent the cylinders from advancing on to the needles corner-wise, from
any failure to make a full turn in working, the end 6 of the bell-crank lever b, is
normally in position, through the spring 63 to act as a trip for one cylinder, and a
corresponding attachment n, shewn in Fig. 2. performs a like office for the opposite
cylinder.
Fig. 2. shews the method of actuating the catch m for moving forward the
cylinder k. by the automatic action of the loom. Connected to the batten g. by
link o. is a lever P. fulcrumed at r, and to the upper end of which is loosely
attached one end of the catch m.
The battens g. 91 are connected, in the ordinary way, by link rods, which
are merely indicated, in the drawing, by dotted lines, for the sake of clearness.

As the batten g. moves inwards, the batten g' is forced outwards, and, at the
same time, the catch m is moved in the same direction as its cylinder, but at a
quicker speed, falling over the cylinder "nog at or about the extremity of its
outward stroke. In the return or inward movement, the catch, by virtue of
its leverage passing over a greater space than the cylinder "nog,"
pulls the
latter over, and turns the cylinder one card, slightly in advance of the
turn of the opposite cylinder, which is turned on the outward stroke, as will be
well understood.
Thus the turning of the cylinders, instead of being alternate, is nearly
simultaneous.
To the catch 1, actuating the
shewn in Figs. 3. and 4. which is
bolts t. t.
This nose-piece forms what may be termed a false-catch, which rides upon
the cylinder
<< nog' "² and keeps the catch 1. out of action for a longer period
than the shorter nose of the catch proper could do alone; but when the false
catch at length falls over the nog 2 the latter, ou the return stroke of the batten,
merely slides the nose-piece along into the position shewn in Fig. 4, only turning
the cylinder when it comes in contact with the real catch. By this means, the
cylinder h. does not turn until it is clear of its needles, and both catches fall into,
or are kept out of gear simultaneously, whereby in the event of any partial
turning back of the loom, one cylinder cannot turn without the other. Also, so
long as the catches are out of gear with their "nogs," the loom may be put back
to some extent without the cylinders turning. Variations in the detail form of
mechanisms for ensuring the accomplishment of the simultaneous or nearly
simultaneous action of the jacquard cylinders in their forward automatic action,
and also in turning them backwards by hand operation may be made without
departing from the peculiar character of the invention.

Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In jacquards for weaving, or other textile manufacture, the simultaneous or
nearly simultaneous action of the cylinders, in lieu of the alternate action thereof,
for the changing of cards, both in the forward movement of the loom, and in the
turning back of the cylinders and cards, for the purpose and in manner substantially
as herein shewn and described.

apparatus herein described, for the purpose and in manner substantially as herein
set forth.
