Improvements in Jacquards and in Apparatus Connected therewith.
We, WILLIAM JOHN RILEY, and ARTHUR PROCTOR RILEY, of Colne, in the County
of Lancaster, Manufacturers, do hereby declare the nature of this invention to be as
follows:-
The improvements relate to jacquards employed for weaving in looms, and in
apparatus connected therewith; and have for object the stopping, by automatic means,
the motion of the loom and jacquard machinery, when the cards of such jacquard are
working incorrectly, or when the cards become entangled, or lap round the cylinder,
or when they are working off the pegs, or out of proper time.
To accomplish this and to effect our improvements, we attach to one of the hooks of
the jacquard an elastic cord, or a cord or cords or wires having a spring in circuit or other
connecting means, may be employed, the other end of which is attached to a second
hook of the jacquard. These hooks may be any which are convenient, but by
preference we select one at the front, and another at the back of the machine.
This connection is so made thai when a card causes the one hook to be lifted it pulls
the second hook on to the knife or lifter, ready for the next motion or lift of the
machine.
This second hook is in connection with a lever or levers, or other equivalent
mechanism, which is caused to act upon a catch or lever in communication with the
weft fork or other stopping motion of the loom, and is so arranged that when the
second hook is allowed to remain on the knife or lifter, the act of lifting the same will
put in motion the mechanism for stopping the loom, either by pressing or pulling
down the weft fork, or by pulling or pressing off the strap fork direct, or by any other
convenient stopping motion existing or applied.
In practice this is controlled by the punching of the cards for operating the two
hooks aforesaid. Every time the first hook is caused to lift, the second hook is
pulled on to the knife, and if not interfered with would lift and stop the loom as
described. But the next card or second motion of the card is so punched that
this second hook is immediately knocked off again, and by so punching the cards
TD 077

page_text: that the first hook is lifted three times in succession and then allowed to remain
down for six movements or in any other suitable sequence--a continuous motion is
secured so long as the cards are working correctly.
If, however, any overlap of the cards takes place, or the cards lap round, or get
displaced on the cylinder, the sequence is broken, and the apparatus described stops
the loom.
In place of levers and cords, or wires, cords or wires and pulleys may be employed,
and by these means the weft fork may be pulled down direct.
The apparatus may be also applied to jacquards of other textile machinery than
looms, as for example that of lace machinery.
Variations in detail may be made without departing from the peculiar character of
the invention.

Improvements in Jacquards and in Apparatus Connected therewith.
We, WILLIAM JOHN RILEY, and ARTHUR PROCTOR RILEY, of Colne 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 :-
The improvements relate to jacquards employed for weaving in looms, and in
apparatus connected therewith, and have for object the stopping, by automatic means,
the motion of the loom and jacquard machinery, when the cards of such jacquard are
working incorrectly, or when the cards become entangled, or lap round the cylinder,
or when they are working off the pegs, or out of proper time.
To accomplish this and to effect our improvements, we attach to one of the hooks of
the jacquard an elastic cord, or a cord or cords or wires having a spring in circuit or
other connecting means may be employed, the other end of which is attached to a
second hook of the jacquard. These hooks may be any which are convenient, but by
preference we select one at the front, and another at the back of the machine.
This connection is so made that when a card causes the one hook to be lifted it pulls
or pushes the second hook on to the knife or lifter, ready for the next motion or lift of
the machine.
This second hook is in connection with a lever or levers, or other equivalent
mechanism, which is caused to act upon a catch or lever in communication with the
weft fork or other stopping motion of the loom, and is so arranged that when the
second hook is allowed to remain on the knife or lifter, the act of lifting the same will
put in motion the mechanism for stopping the loom, either by pressing or pulling
down the weft fork, or by pulling or pressing off the strap fork direct, or by any other
convenient stopping motion existing or applied.
In practice this is controlled by the punching of the cards for operating the two
hooks aforesaid. Every time the first hook is caused to lift, the second hook is pulled
on to the knife, and if not interfered with would lift, and stop the loom as described.
But the next card or second motion of the card is so punched that this second hook
is immediately knocked off again, and by so punching the cards that the first hook is
lifted three times in succession and then allowed to remain down for six movements-
or in any other suitable sequence-a continuous motion is secured so long as the cards
are working correctly.
If, however, any overlap of the cards takes place, or the cards lap round, or get
displaced on the cylinder, the sequence is broken, and the apparatus described stops
the loom.
In place of levers and cords or wires, cords or wires and pulleys may be employed,
and by these means the weft fork may be pulled down direct.
The apparatus may be also applied to jacquards of other textile machinery than
looms, as for example that of lace machinery.
But that the improvements may be better understood we will by the aid of the
accompanying drawing proceed more fully to describe means employed by us.

page_text: DESCRIPTION OF DRAWING.
The figure illustrates one variation of apparatus constructed according to our
invention, and shews two wires and their attachments in skeleton without the framing
or other portions of the jacquard or loom or other machinery.
a, and b, are two hooks or wires of a double cylinder jacquard, and and d, represent
the cross wires which are actuated by the cards at c' and '.
The wire a is arranged to require the hook to be pushed off the grife or knife by
the blank card, and the wire is arranged so as the hook in its normal position will
not be lifted unless by some means pushed on to, or it may be allowed to remain on
the grife or knife.
e, is a wire or other lever, the end of the long leg of which passes through the loop
in the wire a, and the short leg passes through a loop in the wire d at f, or other
means of connection may be employed. This lever is conveniently fulcrumed as at
, in such manner that when the long leg is lifted by the wire a, the wire d is drawn
forward, and the hook of the wire bis thus pulled on to the grife or knife of the lifter
as will be well understood.
A spiral or other spring as at h may be employed where necessary to bring
back the wire and lever.
In operation, if a hole in the card approaching allows the hook of the wire a
to remain on the knife of the lifter, the said wire a lifts the long leg of the
lever and thus presses the hook of the wire b on to the second knife of the
lifter; but if the card approaching d is a blank the hook of the wire 6 will be pushed
off the lifter knife again, which will be permitted by the spring in the long leg of the
lever c facilitated by the curl given therein. On the other hand if d' is permitted by
a hole in the approaching card to remain in the position given to it by the operation
described, then the wire b will be lifted by the knife.
C
At 6 or other convenient point a rod or cord or chain is attached, and is connected
with a lever or levers or pulleys or weights, or other well understood mechanical
contrivances, which are so fixed to the loom or machine as to be capable of actuating the
strap guide driving the loom or machine, or the weft fork of the loom, or any stopping
mechanism whatsoever employed.
In lieu of the lever e a cord or cords having an clastic portion intervening may pass
over pulleys, or connect smaller levers for the purpose of actuating the hook 6 by
means of the hook a, and the hooks may be arranged in different positions and by
reverse action, and other variations of detail 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 :-
The employment of two hooks or wires in jacquard mechanisms so arranged
that one shall operate upon the other, under any suitable sequence in the mode
of punching the cards, in such manner that when such sequence is broken by the
cards being out of proper order of working, one of such hooks er wires shall, by
lifting, stop the loom or machine by actuating the strap guide, weft fork, or other
stopping mechanism, in manner and for the purpose substantially as shewn and
described.
