IMPROVE- MENTS IN CONNECTING CARDS EMPLOYED IN JACQUARDS
Year: 1885

page_text: I, SIDNEY TEBBUTT, of 16 Clumber Street Nottingham, in the county of
Nottingham, Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN CONNECTING CARDS EMPLOYED IN JACQUARDS, to be as follows:-
The cards are used in series, of which the end cards of each series have
frequently to be connected with each other, and disconnected. To accomplish this
I make use of metal buttons or eyelets perforated in their centres, and having the
metal around the said perforation slightly projecting on one side. The said eyelets
are fastened upon the cards either by the projecting centres piercing the cards, and
being rivetted upon the under side of the card, or by a small metal tube or cylinder
passing through each perforation or centre and through the card, and being rivetted
at the one end upon the face of the button or eyelet and at the other end upon the
under side of the card.
These eyelets are placed near the outside or free edge of the card at one end of
each series of cards. Upon the card to be connected therewith, at the other end
of the series, and near its outside or free edge in positions corresponding with, and
opposite to those of the eyelets before named, there are fastened loops, or slings,
made of string, tape, or silk, and of such a size that when the said loop or slings are
passed over the eyelets upon the other card, the edges of the connected cards are
sufficiently close to each other By means of the above described rivetted buttons
or eyelets, the cards may be connected or disconnected with ease and quickness,
and the fastening is one which is not liable to come undone or get out of order,
being substantially as firm and accurate as in the case of the permanently
connected cards of the series and does not interfere with the working of the cards
upon the jacquard.

I, SIDNEY TEBBUTT, of 16 Clumber Street, Nottingham, in the county of
Nottingham, 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 cards are employed in series. They are placed sideways to each other, that
is with the edges of their sides lying towards each other. The cards of a series are
permanently connected, except the two cards, one at each end of the series.
When the series is to be used upon the jacquard, the end cards are connected
together, and when the series is taken off the jacquard, they are disconnected. It
is of great value in saving time that this connection and disconnection should be
made easily and quickly and it is of great importance for good manufacture that the
'connection of the end cards should when made be firm and secure, and that the
means used for the connection or fastening should occupy but little space, and
moreover that the connection should be of such a kind that it will not work loose,
and that the cards will not become farther apart or unfastened. Various modes of
connection have been made use of, but none attain the above objects satisfactorily.
Where the connection is made by tying together the ends with strings fastened to
the cards, it is difficult to attain precisely the proper closeness of contact or
contiguity of the sides of the end cards, and further time is lost in tying and
untying. If the connection is made by passing loops over buttons sewn in the
ordinary manner upon the card, the thread by which the button is held is apt to
become loose, or the texture of the card tears or gives way, and the button soon
works loose or even comes off the card, and thus the firmness of the connection is
lost, and the cards become unfastened, and in consequence the manufacture of the
fabric is damaged or stopped.
In order to obviate these defects I use one or more metal eyelets fastened upon
the cards in the following manner.
The larger eyelets A are made of sheet brass, and may be described as consisting
of two flanges, one much larger than the other and connected at their centres or
eyes by a hollow ring or tubing of metal, the said two flanges and connecting ring
or tubing being one continuous piece of metal. Or they may be otherwise described
as consisting of a face with an eye or hole in the centre, and so punched that the
metal is driven back from the centre so as to project into a kind of hub or ring,
which hub or ring has its edge again turned up outwards into a small flange lying
parallel to the face of the eyelet. One of the larger eyelets A before being
fastened upon the card is shown in section at Figure 1, and in plan at Figure 2,
Figures 3 and 4 show a section and plan of an eyelet B with a projecting centre
and smaller flange, made at an angle to the face of the eyelet as hereinafter
described. Figures 5 and 6 show in section and plan respectively the position and
connection of the eyelet A with the eyelet B when fastened thereby to the card.
It should be observed that the shape of the two eyelets A and B before and after
rivetting is slightly different and that the Figures 1, 2, 3, 4 are before rivetting
and 5 and 6 after rivetting to the card. The said face or larger flange of the eyelet A

page_text: has a diameter of about seven-sixteenths of an inch, the hub or ring projecting
beyond this face about one-sixteenth of an inch, and its edge turned up into a
second flange or rim of a diameter of about a quarter of an inch, that is to say as
much of the metal as is punched out of the centre or eye of the eyelet will allow.
The object of the said rim or flange is to provide a face against which the card can
be pressed when the larger eyelet is rivetted upon the card as hereinafter
described.
The eyelets A are fastened to the card by means of small eyelets B of brass of
such a size as to fit the eye of the larger eyelet, and pass through the said projecting
centre or hub. These eyelets B are small cylindrical thin brass tubes and have
their edges at one end turned up into a small flange just large enough to bite
firmly upon the back of the card C. In order to fasten the eyelet A upon the card
one of the eyelets B is passed through the card, and the hollow centre of the
eyelet A, and is then rivetted down as shown at Figure 5.
In the Drawings the eyelets are shown five times the actual size.
I fasten two or sometimes three of the said eyelets A in the manner above
described upon one of the end cards of the series within a short distance namely
about a quarter of an inch from the free or outside edge of the card, one near each
end and the others between if necessary, the number and position varying
according to requirements. Upon the card at the other end of the series, I fasten,
in positions laterally corresponding with the positions of the eyelets upon the first
card, loops of string of best quality, such loops being of such a size that they may
be respectively passed over the eyelets upon the first card, and when so placed over
will hold the edges of the cards in contact, or as near to each other as may be
required.
By means of the small eyelets B rivetted as described, the eyelet A is held firmly
and securely against the card but with its face or larger flange standing a little
distance therefrom. The loop of the string falls into the groove between the two
flanges (or between the face of the eyelet A, and the flange of its projecting centre,
and lies there upon the projecting centre or hub securely. The surface of the
card being clamped between the smaller flange of the eyelet, A, and the flange or
rim of the eyelet B, is strong enough to bear the strain of the loop upon the eyelet
without giving way or tearing. The end cards of the series can therefore by the
above described means be connected with ease, quickness and precision, and in such
manner as accurately to maintain the distance required for the cards to be apart,
and can be disconnected also with the same facility.
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 :-
The method of connecting and disconnecting jacquard cards by the use of metal
eyelets of substantially the shape of the eyelets herein before described as eyelets A,
fastened upon the said cards in the manner herein before described or in some
manner substantially similar, by eyelets of the shape of the eyelets hereinbefore
described as eyelets B, or of some shape substantially similar.

page_text: I, SIDNEY TEBBUTT, of 16, Clumber Street, Nottingham, in the county of
Nottingham, Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS APPLICABLE TO MEASURING INDICATORS, to be as
follows:-
I employ two cones of similar size and shape placed with their axis parallel,
as near as may be, to each other, and at such a distance that the surfaces of the
cones are but a short distance apart. The cones are placed in reversed position
towards each other, that is to say, the thick end of the one is next to the thin end
of the other. These cones are mechanically connected by an endless belt which
passes round both, so that one cone being moved drives the other. One cone, which
I herein call the first cone, is driven by the machine whose speed is to be indicated,
the other, which I call the second cone is driven by the before mentioned belt.
The axle of the second cone actuates the hands of the Indicator, either directly or
through a train of wheels. The belt which connects the two cones is retained and
moved by a fork adjusted in its position in the usual manner, so that the belt can
be by this means shifted along the surface of the cones longitudinally to any
desired place.
By reason of the varying proportion, which the circumference of the one cone
bears to the corresponding opposite circumference of the other at various points
between their ends, the speed with which the axle of the second cone actuates the
hands of the Indicator, can, by shifting the belt as before mentioned towards one
or other end of the cone, be increased or diminished within certain limits without
any alteration taking place in the speed of the machine which drives the first cone,
that is, the machine whose speed is to be indicated.
In some cases the following modification of the above apparatus will be found
useful. In the place of one of the cones and of the said driving belt, a wheel or
disk is made use of having upon its circumference a covering of india-rubber.
This wheel or disk runs longitudinally upon a square shaft or axle which is placed
Dan 31

page_text: in a direction parallel to the surface of the cone, and at such a distance from it, that
the circumferences of the disk and of the cone, are in close contact. The square
axle may be driven by the machine to be indicated, or the axle itself may actuate
directly, or indirectly, the hands of the indicator and the said disk is retained in its
place, or shifted longitudinally along its square axle, by means similar to those
described above where there are two cones. By the above described apparatus
I obtain the means of increasing or diminishing the speed with which the indicator
is driven by the machine whose speed is to be indicated, and I am thus able to
adjust within limits sufficiently wide for great practical advantage, and to the
greatest accuracy, the proportion which the speed of the indicator bears to that of
the machine whose speed is to be indicated. ¿5

page_text: or Revolution Counters.
I, SIDNEY TEBBUTT, of 16 Clumber Street, Nottingham, in the county of
Nottingham, 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:→
:
When a machine is connected with an indicator or revolution counter, the speed of
the latter and consequently its rate of indication will be governed not only by the
speed of the driving machine, but also by the proportion which the driving wheel
of the machine bears to the wheel of the indicator which it drives. The manner
in which the connection between the machine and the indicator is made in con-
sequence of the cost occasioned by the use of absolute gearing, is sometimes by
turned wheels or pulleys and a band. In these cases although care may be taken
to turn the wheels of a proper size, and duly adjust the bands it is found in practice
that great accuracy is very difficult to obtain and consequently that inaccurate regis-
trations are made, and also that indicators are not interchangeable with all machines
even of a similar construction. Again in many cases what is required to be indi-
cated is not the speed of the driving machine, but the movement on or upon the
machine of some textile fabric placed on or manufactured by the machine. But
considerable variations are found to occur in length of the fabrics made on a
machine according as to the nature of the material, its tendency to run together;
the thickness or dampness of the fabric and other causes and hence the indicator
may indicate correctly for a machine at one time, and incorrectly at another and
similar variations and inaccuracies arise, where it is desired to indicate the rate of .
action of machines throwing, or raising or otherwise dealing with grain or liquid,
or such like matter.
In order to obviate the above mentioned difficulties I employ the following
apparatus to adjust the speed of the indicator to any given amount, and thus make
the record of its hands an exact and absolute record instead of one needing
correction.
I employ two cones of similar size and shape whose axles run on bearings in the
frame which also holds the indicator. These cones are placed with their axles
parallel, but in reversed position towards each other, that is to say with the large
end of the one opposite the small end of the other. These cones are of the ordinary
shape of conical pullies, used by mechanics, and have no apex. The cones I prefer
to use in the special indicator used with lace curtain machines are about 1 inches
in length, and the diameter of each cone at the one end is about one inch and an
eighth and at the other end one inch and a quarter. But the size of the cones and
their relative size one to the other may vary according to practical requirements,
as for instance where the indicator is large and requires considerable power to drive

page_text: it, the size of the circumference of the cones, and of their axles, and of the frame
carrying them will be increased, and in cases of the opposite kind, they will be
diminished. And again where it is desired to adjust the speed of the indicator to
unusual accuracy, the difference between the sizes of the ends of the cone will not
be great, that is the diminution of the size of the cone from the larger to the smaller
end will be very gradual. In all cases however the taper of the two cones must
be the same.
The axles of the cones are placed at such a distance apart that their circum-
ferences are near each other, the distance I prefer in the case of the size given above
as of those cones I use for lace curtain machines is about an eighth of an inch, but
this distance may vary according to practical requirements.
The cones are mechanically connected by an endless leather or india-rubber belt
which passes round the circumference of both cones with sufficient tightness to
produce complete and uninterrupted mechanical connection. The belt is shifted
longitudinally along the surface of the cones by a fork which is moved from side
to side and retained in any required position by a long screw, or by any suitable
mechanical means.
The axle of the first cone passes through the frame of the indicator (in the form
I prefer to employ) and is driven either by a band or by gearing from the driving
machine. The axle of the second cone carries a small cog wheel which is geared
with the wheels of the indicator. Figures 1 and 3 represent the particular
arrangement I prefer to use of cones in connection with an indicator, Figure 1
shows a side view of cones with guide or fork and screw removed, and Figure 3
the same but with guide and screw in position, and Figure 2 shows a sectional
view of Figure 3. In all the said Figures A represents the axle of the first cone,
which is driven by mechanical means from the machine to be indicated, B is the
first cone, C is the axle of the second cone, D the second cone, E the connecting
belt, F the guide or fork upon the screw G, Ha handle by which the screw is
turned, and the belt brought into the required position upon the cones, K is the nut
by which the screw is locked in any required position. There is also a rod L passing
through the projected arms of the fork to keep it from turning, which is shown in
Figure 2, M is the toothed wheel on the axle of the second cone which gears with
and actuates the wheel of the indicator.
The mode of action of the above described apparatus is as follows. The machine
to be indicated drives the axle of the first cone and hence the whole apparatus, and
the indicator. If the hands of the indicator revolve too fast and record too
much the belt E is shifted by the fork F along the surface of the cones towards
the small end of the first cone B, and from the small end of second cone D, if
on the other hand the indicator records too little the belt is shifted along the
surface of the cone in an opposite direction. In certain cases I find a modification
of the above apparatus advisable. In the place of the second cone I use an iron
wheel of as large a diameter as can be practically used, say one and a half times
as large as the large end of the cone, the exact size however is unimportant.
This wheel has upon its rim suitably grooved for the purpose a tyre of india-
rubber or similar elastic material of about three sixteenths of an inch thick;
ordinary vulcanized indiarubber as used for bicycle wheel tyres is very suitable.
The iron wheel has a square hole in its centre, and slides freely upon a square
axle. The square axle is placed in a direction parallel to the surface of the cone
and at such a distance from it, that the indiarubber tyre on the wheel is in close
contact with and bites the surface of the cone. The wheel or disc may be moved
longitudinally along its square axle and held in any desired position by a fork
similar to the means employed for a like object, in the case of the two cones before
described. Figures 4 and 5 shew in plan and section the particular arrangement
I prefer to use, and in which the letters of the various parts correspond to those
of the Figures previously described, except that C is the square axle, and D is
the disc or wheel with an india rubber tyre. As the wheel D is shifted along the

page_text: surface of the cone towards its smaller end, the cone will drive the wheel slower,
and as the wheel is shifted the contrary way, the cone will drive it quicker, and
thus the speed with which the indicator is driven can be varied by turning the
handle of the screw which carries the fork F.
In consequence of the gradual sloping surface of the cones or cone in the above
described apparatus, the rate of speed with which the indicator is driven can be
varied and adjusted within limits, (which though not large are wide enough for
great practical utility) to the greatest nicety and with the greatest precision, a result
which as far as I am aware can in no other manner be so easily and advantageously
obtained.
It is applicable to all indicators constructed upon the ordinary patterns and
although the necessity remains of having specially designed indicators for various
classes of fabrics and of machines, yet it renders such indicators capable of
making an absolutely accurate record instead of one needing correction and
calculation.
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:-
The use of two cones lying in reversed position towards each other and
mechanically connected by an adjustable belt as hereinbefore described, or the use
of a cone and a disc or wheel moveable along its axle mechanically connected as
herein before described, or the use of some apparatus substantially similar thereto
in connection with speed indicators or revolution counters, for the purpose of
differentiating and adjusting the speed of the said indicators or counters.
