I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign Patent
Solicitors, 6 Lord Street Liverpool, in the County of Lancaster, and 323 High
Holborn, in the County of Middlesex, Civil Engineer, do hereby declare the nature of
this invention to be as follows:-
The present application for Letters Patent has for its object an indicating and
counting apparatus enabling the weaver to stop in the manufacture of a fabric exactly
at a given point, and commence a decoration of any kind, such as the border of a
napkin for instance; this indicator serves at the same time as a counter, indicating at
any moment the amount of work done longitudinally or laterally.
Between the two uprights of a frame, fastoned together above and below are
mounted two rollers. The upper cylinder is fixed upon an axle, and has a roughened
surface, the lower cylinder is mounted upon an axle which revolves in slots cut in the
end of two bearing levers. Spiral springs fixed to the other ends of these levers tend
to press constantly the lower cylinder against the upper cylinder. The lower
cylinder or regulating roller, set in motion by the passage of the fabric between the
two cylinders, actuates by means of a set of gearing, an indicator, and the register or
counter. The last wheel of the series is furnished with a circular plate, bearing on
its periphery a strip of paper previously marked with divisions; a fixed pointer serves
as indicator, and rests on the strip. Knowing the length of the circumference of the
regulator roller, and the number of teeth in the pinion, mounted on the same
shaft, it is easy to determine, according to a given amount of fabric unrolled, the
number of teeth to be given to the wheel to cause it to make one turn every time that
the desired length of fabric has passed between the two rollers; each time that the
mark arrives opposite the pointer, it will consequently indicate that the desired length
of material has been caused to pass between the two rollers. The shaft of the pinion

page_text: turns by means of a worm, a corresponding wheel, which actuates by a shaft the needle
of the counter on the dial advancing it by a tooth at each turn of the pinion. By this
arrangement one can see at a glance the number of lengths of stuff, which have passed
between the two rollers.
•
In further explanation of the mode of action of the invention, suppose that it is
desired to weave a napkin 80 centimetres long with a border placed 14 centimetres
from the edge. If the regulating roller have 40 centimetres circumference, the
proportion between the number of teeth in the one pinion, and of the other must be as
1 to 2 in order that the said pinion may make one turn to each napkin length passing
between the rollers. To enable the weaver to stop at 14 centimetres from the edge,
there are marked at 14 centimetres from the mark on the disc, two other marks of
different colour, one before and one behind, and when these marks come under the
index, the weaver stops to weave the border, at the same time he only needs to look
at the dial, to ascertain the exact number of napkins woven.
By means of this cheap and easily constructed apparatus, the manufacturer can
obtain napkins of perfect regularity. There will also be a differenco in the wearing
because the loom will certainly work better when the weaver is no longer obliged to
count the napkins, nor to alter after each piece is finished, his steel chain or string
which gives the length, and which often tangles, breaks, or stretches. With this
apparatus the hand working of the edges with the borders marked with black marks
is thus avoided; these marks injure the appearance of the fabric, and often cause
the goods to be rejected if too apparent.

page_text: A communication from abroad by DÉSIRÉ CHIPART FILS, of Armentières, in the Republic
of France, Manufacturer of Table Linen.
I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign Patent
Solicitors, 6, Lord Street, Liverpool, in the County of Lancaster, and 323, High
Holborn, in the County of Middlesex, Civil Engineer, 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 present application for Letters Patent has for its object an indicating appliance.
which enables the weaver to stop exactly at a given point in the weaving of a fabric
for the purpose of commencing a decoration of any kind, such as the borders of table
napkins for instance; at the same time this indicating appliance serves as a counter,
so that whenever desired the quantity of work done may be ascertained either in
length or in number. Moreover the system of indicating appliance is characterised by
the application of an instantaneous automatic stop or release, devised to stop the loom
at the exact moment when the parts of the mechanism which weave the decoration are
to be put in motion without requiring the personal attention of the workman, except
to replace the mechanism at a given moment in position to repeat this releasing action.
In order that the invention may be fully and clearly understood the inventor has
represented in the accompanying drawing a view of the invention by way of
illustration.
In the drawing Figure 1 shews a general view of the apparatus.
Figure 2 is a plan.
Figure 3 a detail view of a portion of the mechanism.
In all these Figures the same letters of reference are applied to the same parts.
Between the two uprights a and b of a frame joined together above and below are
mounted two cylinders c and d. The cylinder c is fixed on the shaft e and has a
roughened surface f: the cylinder d is mounted upon a shaft revolving in hollows cut
out at one end of each of the levers g: spiral springs h attached to the other end of
each of these levers tend to hold the cylinder a constantly applied against the
cylinder c. The cylinder d or regulating roller is set in rotary motion by means of
the passage of the fabric between the two cylinders c and actuates by means of a
train of gearing the indicator i and the register or counter by means of a handle a¹
in connection with a shifting piece b' fixed on the main shaft. The counter may
obviously be of any desired kind indicating by pointers or. by means of wheels or
otherwise and shewing at any moment the number of napkins finished to that point
The last gearwheel of the series m is furnished with a platen bearing on its periphery
a paper band p having one or more guide lines g on it, a fixed pointer r serves as

page_text: indicator and presses on the band p. The length of the circumference of the
regulating roller and the number of teeth in the pinion s mounted on the shaft thereof,
being known, it is easy to determine according to the length of fabric it is desired to
divide off the number of teeth to be given to the wheel m in order that this latter should
make a turn each time that the desired length of fabric bas passed between the two
rollers. Each time that the mark q arrives opposite the pointer r, one may be sure
that the required length of stuff has passed between the two rollers.
The system of stopping mechanism consists of a metal box c¹ attached to the
apparatus in which works a little piston d¹ provided with a stop u¹ controlled by a
spiral spring el. A little fixed bar f¹ and a moveable hinged piece g' are fixed on the
piston which escapes from the retaining notch ³ every time that the hinged piece
is oscillated on the little bar by the passage of one of the teeth t attached to the
indicator n.
This is accomplished as follows
When the piece hereafter described has interposed itself between p¹ and the little
catch g', the mechanism which operates in the metal box C is disconnected, that is to
say, the stop u has being released from its notch h' and that under the pressure of the
spring e¹ the piston d' and all that it carries has been carried backwards. In consequenco
of the disconnection, the moveable joint g' has also been carried backwards, and is not
any longer facing the teeth t¹ which cause it to move. But when the mechanism is
connected is in the notch h¹ and the joint g¹ is so placed in respect to the teeth t
that if one of these teeth were to pass, it would cause it to revolve round its axis, then
push against the lever f¹, whereby a slight rotary motion is given to the piston d',
thereby releasing the stop u from the notch and causing the disconnection of the
system.
In escaping the piston causes the instantaneous stoppage of the loom as follows: to
the end of the little piston there is attached a string k which passes along the breast
piece and is fixed to the piece l' fixed on a pivot m' attached to the frame. Every time
that the piston d' escapes, the string being relaxed, allows the piece l' to be drawn down
by the spring n', this piece in oscillating places itself behind the detent pl of the loom,
and is impelled at the same moment by a little catch g' attached to in movement
the piece placed at this moment between the catch and the stopping bar, forces
the latter to recede and to quit the stop notch s', the release of the loom is effected
instantaneously. The regular operation of the mechanism is checked by means of
the indicator, the pointer of which should be exactly on the mark at the moment of
the stoppage of the loom. This stopping arrangement is especially useful, or one might
say indispensable in weaving sheds where each workman conducts two looms.
To more clearly set forth the operation of the invention, suppose that it is desired
to weave a napkin 80 centimetres in length having a border at a distance of
14 centimetres from the edge. Supposing that the regulating roller has a cir-
cumference of 40 centimetres, it will be requisite that the proportion between the
number of teeth of the pinions and those of the wheel m be as one is to two, in order
that the wheel m may make one turn for each length of napkin which has passed
between the two rollers.. In order that the weaver may stop at 14 centimetres from
the edge, the inventor marks at a corresponding distance from line q upon the disc
a line of another colour in front, and another behind, and when these two marks reach
the pointer
the apparatus is arranged to act and stop the loom, thus permitting the
weaving of the border by means of the teeth t¹ placed at a suitable distance upon the
indicator q: these teeth are moreover mounted so as to be adjustable and can be set
forward or back as required.
With this cheap and easily constructed apparatus the manufacturer can produce
napkins of perfect uniformity, he will also obtain an improved out put, because the
loom will certainly produce more when the weaver is no longer obliged to count the
napkins nor change after each piece is woven the steel chain or string which gives
the length, and which is liable to tangle, stretch, or break. With this apparatus the
hand-working of the borders with patterns indicated by black marks is also obviated
together with all the difficulties connected therewith. Moreover the suppression of the

page_text: black marks on the edges of the fabrics where the borders are to be worked is an
advantage because these marks detract from the appearance of the fabric and are
often the cause, if too visible of the goods being rejected by buyers.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is,
1. A system of indicating and counting apparatus, specially applicable to looms
for weaving, and characterised by the combination of a counting device, which
will register in the manufacture of napkins for instanco, the number of pieces
woven with an indicating apparatus which enables the workman to ascertain at any
moment the length of the fabric woven, and with an automatic stopping device, devised
to stop the loom at the precise moment when requisite, whether for the purpose of
commencing a fresh work such as a decoration for instance, or for any other pre-
arranged.object.
2. In a system of indicating and counting apparatus, substantially as set forth in
claim 1, the combination of drawing rollers, dc for the fabric with a train of gearing
of which the last one is mounted upon the shaft of a counter 4, or otherwise controls
the same, this combination forming the registering device which enables the workman
to ascertain at any time the number of finished articles or length of material which
has passed between the rollers.
3. In a system of indicating and counting apparatus, substantially as set forth in
claim 1, the indicating device consisting essentially of a disc n mounted upon the
shaft m and having upon its periphery a strip of paper p upon which are marked
the guide lines q, in combination with the fixed points r.
4. In a system of indicating and counting apparatus as specified above, the
automatic rolease apparatus devised to stop the loom at a given moment, and consisting
essentially of the little piston d' provided with stop u' and capable of oscillating when
actuated by the movable hinged piece g¹, so as to dislodge the stop u from its
notch h¹ with the teeth t' attached to the indicator i, the string k¹ and the piece 1, which
last is devised to place itself at the moment when the stop u¹ has been released behind
the stop p, causing p' to be struck by the little striker q' fixed to the moving apparatus
and consequently to stop the loom.
All substantially as and for the purposes described and illustrated in the
accompanying drawings, and in combination or separately.
