I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex,
do hereby declare the nature of this invention to be as follows:-
In looms for weaving fancy cloth as heretofore used, actuated by treadles or other
equivalent means, faults or defects in the pattern obtained by the use of perforated
Jacquard cards frequently occur, by the occasional irregular action of one or more
of the levers the required movement of which is determined and regulated by the
action of the cards, such faults or defects being not readily noticeable by the weaver
during the working of the loom.
The object of the present invention is to provide supplementary apparatus by which
the motion of the loom is automatically stopped, should such a fault occur from any
cause as for instance by two or more of the levers catching and rising together, or
failing to rise at the required time for any reason.
The improved apparatus consists of a separate frame formed upon or fixed to the
main frame of the loom, and having at its upper end a transverse bar upon which
turn the lower ends of a number of levers corresponding in number with the main
levers of the loom to which they are connected at their upper ends by a corresponding
number of rods.
Each lever has jointed to it at its lower end upon each side of the bar upon which
it turns, a vertical wire or needle, which needles pass through guides properly arranged
so that their lower ends rise and fall as the levers oscillate.
Beneath the lower ends of the needles is arranged a card cylinder turning upon a
central axis one end of which is fixed in a lever the outer end of which is pivotted upon
a bracket upon the frame whilst its other end works in and against a guide. The
cylinder has sides corresponding with those of the principal card cylinder of the
loom, but of greater width so that each card can receive two rows of perforations at a

page_text: distance apart corresponding with the distance between the two rows of needles
above it, the perforations in both cylinders corresponding with the pattern to be
woven.
The card cylinder is provided at each end with projecting pins or teeth which
enter corresponding holes near the end of the cards, so that the latter are carried
forward in the usual way when the cylinder revolves, and at the inner end of the
cylinder are arranged pins or teeth which are caught by hooks upon two bars, one
upon each side of the cylinder, which bars are caused to rise and fall alternately by
the oscillation of the levers and so to cause the revolution of the card cylinder step
by step at the proper times. A bar or plate is fitted upon the lever by which the card
cylinder is carried as already described, and is pressed by a spring against one side
of the pins last described, so as to hold the cylinder steady when it is not turning.
The outer end of the lever or the bar upon which the card cylinder turns is provided
with an arm or bar by means of which when the lever is depressed disengaging
mechanism is set in motion by which the motion of the loom is stopped in the usual
way.
In operation the principal card cylinder of the loom is first moved in the usual
way, and immediately after and almost simultaneously, the supplementary card cylinder
described. The latter indicates to the weaver that the loom is operating correctly
and the pattern being woven without fault, but if for any reason any of the levers of
the loom rise together at the wrong time so as to cause a defect in the pattern, the
needles corresponding with them, as first described, are unable to enter perforations
in the supplementary cards and the disengaging bar is consequently depressed
and the movement of the loom suspended, until the defect has been remedied.

An Automatic Stop-motion for Fancy Cloth Looms.
A communication to me from abroad by ERWIN WELLER and THEODOR BAUER, both 3
of Gera, in the Empire of Germany, Mechanicians.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and Engineers,
of 35 Southampton Buildings, Chancery Lane, in the County of Middlesex, 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 3
statement and accompanying drawing, that is to say :—
In looms for weaving fancy cloth as heretofore used, actuated by treadles or other
equivalent means, faults or defects in the pattern obtained by the use of perforated
Jacquard cards frequently occur, by the occasional irregular action of one or more of
the levers the required movement of which is determined and regulated by the action 4

page_text: of the cards, such faults or defects being not readily noticeable by the weaver during
the working of the loom.
The object of the present invention is to provide supplementary apparatus by which
the motion of the loom is automatically stopped, should such a fault occur from any
cause as for instance by two or more of the levers catching and rising together, or
failing to rise at the required time for any reason.
The improved apparatus consists of a separate frame formed upon or fixed to the
main frame of the loom, and having at its upper end a transverse bar upon which
turn the lower ends of a number of levers corresponding in number with the main
levers of the loom to which they are connected at their upper ends by a corresponding
number of rods. Each lever has jointed to it at its lower end upon each side of the
bar upon which it turns, a vertical wire or needle which needles pass through guides
properly arranged so that their lower ends rise and fall as the levers oscillate.
Beneath the lower ends of the needles is arranged a card cylinder turning upon a
central axis one end of which is fixed in a lever the outer end of which is pivotted
upon a bracket upon the frame whilst its other end works in and against a guide.
The cylinder has sides corresponding with those of the principal card cylinder of the
loom, but of greater width so that each card can receive two rows of perforations at a
distance apart corresponding with the distance between the two rows of needles above
it, the perforations in both cylinders corresponding with the pattern to be woven.
The card cylinder is provided at each end with projecting pins or teeth which enter
corresponding holes near the end of the cards, so that the latter are carried forward
in the usual way when the cylinder revolves, and at the inner end of the cylinder are
arranged pins or teeth which are caught by hooks upon the bars, one upon each side
of the cylinder, which bars are caused to rise and fall alternately by the oscillation
of the levers and so to cause the revolution of the card cylinder step by step at the
proper times. A bar or plate is fitted upon the lever by which the card cylinder is
carried as already described, and is pressed by a spring against one side of the pins
last described, so as to hold the cylinder steady when it is not turning. The outer
end of the lever or the bar upon which the card cylinder turns is provided with an
arm or bar by means of which the lever is depressed and the disengaging mechanism
is set in motion by which the motion of the loom is stopped in the usual way.
In operation the principal card cylinder of the loom is first moved in the usual way,
and immediately after and almost simultaneously, the supplementary card cylinder
described. The latter indicates to the weaver that the loom is operating correctly
and the pattern being woven without fault, but if for any reason any of the levers of
the loom rise together at the wrong time so as to cause a defect in the pattern, the
needles corresponding with them, as first described, are unable to enter perforations
in the supplementary cards and the disengaging bar is consequently depressed and
the movement of the loom suspended, until the defect has been remedied.
The accompanying drawings are in illustration of the invention:- Figure 1 being
a perspective view of the improved control apparatus; figure 2 a side view; figure 2ª
a modification of the position of the hooks K K'; figure 3 a front view; figure 4 a
cross section following the line a-b figure 3; figure 5 a section through the double
card cylinder; figure 6 the pattern or card; figure 6ª the control card; figure 7 a
front view of the disengaging mechanism; figure 7 a side view of the same
mechanism; figure 8 a side view of the cylinder lever; figure 8ª a front view of the
same; figure 9 a front view of the whole disengaging mechanism; and figure 10 a
side view of the same.
The same letters represent the same parts in the several figures. A A¹ are the
levers of the loom, which turn upon the shaft A³ carried in the frame A2 of the loom.
Against the upper swinging ends of the levers rest at B₁ the bars B of the control
apparatus.
The following letters refer all to the control apparatus.―
Care the levers of the needle board, D the frame of the control apparatus ; E double
card cylinder provided with the pins E¹; F the cylinder lever; G the slide or guide
of the cylinder; H the needle board or frame; F beam or support, of iron; K, K¹, the

page_text: two hooks which move the cylinder; L a bar or plate holding the cylinder in its
position; M cylinder spring; N joining spring; O disengaging piece; P cam;
Qcranked spring; R stop pin; S stop spring; T excentric rod guided in bar or
rod U, and operated by excentric V; W guide of the stop mechanism; Z needles.
The fancy cloth loom as ordinarily used is provided with a single card cylinder
only, over which pass the perforated cards or chain of cards m, forming the pattern
or design (see the perforations O, figure 6) in the well known manner.
The control apparatus is provided with the double cards n, which are perforated
according to the same design as the cards m and in addition with the control
perforations p.
The single card cylinder of the loom works first, after which, but nearly
simultaneously, the double or control card cylinder operates, with and upon the
cards n.
This latter indicates to the weaver if all is going on properly and in a right way,
and if any defect arises, the disengaging mechanism comes into operation, and stops
the motion of the loom.
This latter movement is operated every time that the levers A of the loom fail to
operate properly and the needles are consequently prevented from entering into the
perforations of the control card.
Such failure takes place if two levers are pressed against one another, and by this
pressure one of them or both cause a fault. The cylinder at once stops because the
hooks K do not work upon it and the disengaging mechanism O is immediately
pushed downwards, by which movement the bevelled bar W, which carries a small
weight, falling downwards and catching in the hook Y, pushes against and operates
the ordinary disengaging mechanism of the fancy loom, (see figure 7").
The disengaging bar W rests directly upon the breast beam, and is consequently in
direct relation with the disengaging mechanism of the loom.
The normal and stopping position of the needles and hooks is represented in figure 2 ;
the working position in figure 4.
The rotation of the cylinder E is effected by the two hooks K K' in their alternating
movement caused by the motion of the levers C; the position of the hooks may vary
between the limits indicated in figures 2 and 2ª.
The feed or carrying forward of the perforated cards is effected by means of the
studs or pins E' fixed upon the two edges of the cylinder E, which enter the perforation n'
in the control card.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
A control apparatus for fancy cloth looms of all kinds, for avoiding faults in woven
fancy cloths, such apparatus consisting of a supplementary framework D, in which is
carried a double card cylinder E, the control cards or control card chain n, operated
by means of the two hooks K, K¹, a needle board H with the needles Z, Z' which are
set in movement simultaneously with the levers A of the loom, and a disengaging
mechanism consisting of the parts O, P, R, S, Q, U, T, and W, the entire mechanism
being joined to and in connection with the fancy cloth loom, by means of the levers
or bars B, substantially as described and shewn in the drawings.
