Improvements in Pattern Card Chains for use in Weaving.
I ERNEST DUTCH of 97 Dickenson Road Rusholme Manchester in the County
of Lancaster, Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
My invention consists in improvements in pattern card chains for use in weaving
and consists in means whereby I am enabled to facilitate the building up of
pattern card chains according to the designs required and also in means whereby
I enable the pattern on a pattern card chain or a portion of a pattern card
chain to be altered or changed without destroying the continuity of such pattern
card chain or such portion of a pattern card chain and so save much of the care
and time which have hitherto been spent in building up pattern card chains card
by card.
According to the first part of my invention I form a chain the links of which are
formed of wire or other suitable material bent into such a form that each of such
links or each pair or set of such links shall be adapted not only to act as a
connecting portion or portions of such chain but shall be also so formed as to
be adapted to carry a card or plate which may be placed and securely retained
thereon and may also be removed therefrom without disconnecting such link or
pair or set of links from the adjacent links of such chain. By the employment
of this part of my invention I am enabled to greatly facilitate the building up of
pattern card chains according to any required pattern and so save much of the time
and care hitherto involved in the setting or building up of pattern card chains
where each card or plate has itself formed a connecting portion of such chains.
According to a second part of my invention I. form each card or plate of a
pattern card chain with projections as ordinarily employed to be engaged with or
embraced by the rings employed to connect the cards or plates to one another. I
may form in each projection a slight nick or notch. Across the opening formed by
the two projecting portions at each end of the card or plate I "spring" or place a
piece of band or spring steel or wire or other suitable material which may if
necessary or desirable have a nick or notch formed in each end so that it may be
more securely retained in position after it has been sprung or placed across the
opening formed by the projecting parts to which it is applied. After a card or
plate has been connected by the metal rings as hitherto employed, to those cards or
plates to which in the pattern chain it is required to be adjacent one end of the
piece of band or spring steel or wire or other suitable material to be used with such
card or plate is placed in position in or upon one of the projections before referred
to and the other end of such piece of band or spring steel or wire or other suitable
material is sprung into its required position in or upon the other and adjacent
projection. The projections at the other end of such card or plate being formed in
a like manner a corresponding piece of band or spring steel or wire or other suitable
material is sprung into position in a manner similar to that above described. By
the employment of this part of my invention I am enabled to prevent the rings
connecting the cards or plates in a pattern card chain from becoming disengaged
from such cards or plates and at the same time to dispense with the use of india-
rubber rings and other similar devices which are apt to become disengaged from
the cards or plates or are exceedingly liable to injury when they come into contact
with oil.
A further part of my invention consists in improvements by which I am enabled
to alter or change the pattern on a pattern card chain or the pattern on a portion
of a pattern card chain without destroying the continuity of such chain or such

page_text: portion of a chain and so save much of the time which has hitherto been spent in
building up pattern card chains card by card.
In carrying this part of my invention into effect I employ metal clips formed of
strips of metal of the required shape and size. I may form in one part of each of
such strips or pieces of metal by embossing or other suitable means a slight bulge
or convexity the bulges or convexities being well adapted to retain the clips in
their proper position on the cards or plates. I may however for this purpose
employ any other suitable means. By the employment of clips constructed
according to this part of my invention in conjunction with cards or plates as
hitherto constructed I am enabled by slipping or passing the clips over or partly
around the cards or plates and when the same are provided in such a manner that
the slight bulges or convexities shall enter those holes in the cards or plates which
it is required shall become operative portions of such cards or plates to alter or
change the effects of such cards or plates on the darts or needles in conjunction
with which they act and so am able to alter the pattern on such pattern card chain
without disconnecting the individual cards or plates from one another. By
employing in conjunction with this part of my invention a pattern card chain com-
posed entirely throughout its length of those cards or plates which in pattern card
chains as hitherto constructed are inoperative or productive of no effect upon the
darts or needles in conjunction with which they are used when presented to such
darts or needles I am enabled to readily cause any portion or portions of one, any
or all of the cards or plates constituting a card chain to become operative or
inoperative as required and so am enabled to at any time readily alter the
pattern on such chail or a portion of such chain as required without having to dis-
connect the individual cards or plates from one another. I would have it understood
in reference to this part of my invention that the clips before referred to may be so
formed or constructed that each of such clips when applied to a card or plate may
be capable of rendering one or more portions of such card or plate an operative
portion or operative portions and may be formed of any suitable metal or material
and constructed in any suitable manner.
I would also have it understood that this part of my invention may be used in
combination with either of the above described parts of my invention or in
conjunction with any form of pattern card hitherto in use in pattern card chains.

Improvements in Pattern Card Chains for use in Weaving.
1, ERNEST DUTCH of 97 Dickenson Road, Rusholme, Manchester, in the County
of Lancaster, Mechanical 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:—
My invention cousists in improvements in pattern-card-chains for use in weaving
and consists in means whereby I am enabled to facilitate the building up of pattern-
card-chains according to the designs required and also enable the pattern on a
pattern-card-chain or the pattern on a portion of a pattern-card-chain to be altered
or changed without destroying the continuity of such pattern-card-chain or such
portion of a pattern-card-chain and so save much of the care and time which have
hitherto been spent in building up pattern-card-chains card by card.
My invention consists in improvements by which I am enabled to alter or change
the pattern on a pattern-card-chain or the pattern on a portion of a pattern-card-
chain without destroying the continuity of such chain or such portion of a chain
and so save much of the time which has hitherto been spent in building up pattern-
card-chains card by card.

page_text: In carrying my invention into effect I employ metal clips formed of strips of
metal of the required shape and size. I may form in one part of each of such strips
or pieces of metal by embossing or other suitable means a slight bulge or convexity
the bulges or convexities being well adapted to retain the clips in their proper
position on the cards or plates. I may however for this purpose employ any other
suitable means. By the employment of clips constructed according to my invention
in conjunction with cards or plates as hitherto constructed I am enabled by slipping
or passing the clips over or partly around the cards or plates and, when the same
are provided, in such a manner that the slight bulges or convexities shall enter
those holes in the cards or plates which it is required shall become operative
portions of such cards or plates, to alter or change the effects of such cards or
plates on the darts or needles in conjunction with which they act and so am able to
alter the pattern on such pattern-card-chain without disconnecting the individual
cards or plates from one another. By employing in conjunction with my invention
a pattern-card-chain composed entirely throughout its length of those cards or
plates which in pattern-card-chains as hitherto constructed are inoperative or
productive of no effect upon the darts or needles in conjunction with which they are
used when presented to such darts or needles I am enabled to readily cause any
portion or portions of one, any or all of the cards or plates constituting a card-
chain to become operative or inoperative as required and so am enabled at any
time to readily alter the pattern on such chain or a portion of such chain as
required without having to disconnect the individual cards or plates from one
another. I' would have it understood in reference to my invention that the clips
before referred to may be so formed or constructed that each of such clips when
applied to a card or plate may be capable of rendering one or more portions of such
card or plate an operative portion or operative portions and may be formed of
any suitable metal or material and constructed in any suitable manner.
Several forms of clips constructed according to my invention are illustrated in
the accompanying drawing, in all the figures of which the same letters of reference
are applied to corresponding parts.
Fig. 1 is a front view and Fig. 2 a vertical transverse section of one form of clip
which is formed of a portion of sheet metal bent so as to be capable of being
slipped, pushed or placed upon a card or plate of a pattern-card-chain and of
clipping and so being retained thereon by its elasticity. It is intended that the
leaf (a) of the clip shall act upon the dart or needle upon which such clip is
required to act when the pattern-card-chain, on a card or plate of which it is
employed, is in use, and that the leaf (b) of the clip shall be at the back of the
card or plate to which the clip is applied when in use.
Fig. 3 is a front view and Fig. 4 a vertical transverse section of another form of
clip constructed according to my invention. The clip illustrated in Figs. 3 and 4
is similar to that illustrated in Figs. 1 and 2 except in that in the leaf (a) of this
clip illustrated in Figs. 3 and 4 there is formed a slight bulge or convexity (c)
which when the clip is applied to a card or plate of a pattern-card-chain helps
to retain such clip in position by entering the hole to be covered by means of
such clip.
Fig. 5 is a front view, and Fig. 6 is a vertical transverse section of another form
of clip constructed according to my invention. While being generally similar to
the clip illustrated in Figs. 1 and 2 this clip illustrated in Figs. 5 and 6 is provided
on its leaf (b) with a projecting or turned up edge (d) which when such clip is
placed in position upon a card or plate of a pattern-card-chain will serve to retain
the said clip in position until the two leaves (a) (b) of such clip are separated or
"sprung
apart to such an extent as will permit the said card or plate to be
disengaged from the projecting or turned up edge (d).
"
Fig. 7 is a front view and Fig. 8 a vertical transverse section of another form
of clip constructed according to my invention. This clip illustrated in Figs. 7
and 8 is generally similar to that illustrated in Figs. 3 and 4 but differs therefrom
in being bent into such a form that it is provided with a beading or projection (e)

page_text: which facilitates the removal of the clip from the card or plate of a pattern-card-
chain to which it may have been applied when it is desired that such clip shall be
removed therefrom.
Fig. 9 is a front view and Fig. 10 a vertical transverse section of another form
of clip constructed according to my invention. This clip illustrated in Figs. 9
and 10 has its leaf (a) which is intended to act upon the dart or needle upon
which such clip is to act when in use made similar in shape to the corresponding
leaves of the clips illustrated in Figs. 1, 2, 3, 4, 5, 6, 7 and 8 but has its leaf (b)
which is intended to be at the back of the card or plate, to which the clip is to
be applied made in the form of a narrow strip.
Fig. 11 is a front view and Fig. 12 a side view of another form of clip constructed
according to my invention. In the clip illustrated in Figs. 11 and 12 the leaf (a)
which is intended to act upon the dart or needle upon which the clip is required to
act when in use is made circular in form and formed with a slight bulge or con-
vexity (c) similar to those formed in the clips illustrated in Figs. 3, 4, 7, 8, 9,
and 10 and the other leaf () is made in the form of a narrow strip.
Fig. 13 is a front view and Fig. 14 a vertical transverse section of another form
of clip constructed according to my invention. This clip illustrated in Figs. 13
and 14 is so formed that the leaf (a) which is intended to act upon the dart or
needle when the clip is in use is formed of two thicknesses of metal, the bulge or
indentation (c) being formed in each of such thicknesses of metal, while the other
leaf (b) which is intended to be placed behind the card or plate to which the clip
is to be applied is formed of only one thickness of metal.
Fig. 15 is a vertical transverse section of another form of clip made according
to my invention. This clip illustrated in Fig. 15, has the leaf (a) which is intended
to act upon the dart or needle upon which the clip is required to act when in use
formed of two thicknesses of metal but only the inner of the two thicknesses which
is intended to be in contact with the card or plate to which the clip is to be
applied, is formed with a bulge or convexity (c). The other leaf (b) of the clip
illustrated in Fig. 15 is formed of a single thickness of metal.
Fig. 16 is a front view and Fig. 17 a vertical transverse section of another form
of clip made according to my invention. This clip illustrated in Figs. 16 and 17 is
intended to cover two of the holes in the card or plate to which it is applied and is
formed with two indentations or bulges (c) (c) so that it may be more securely held
in position on the card or plate to which it is to be applied and such clip is provided
with two projecting-strips-or-leaves-(b)-(b) which are passed behind the card or
plate to which the clip is applied in order that they may hold such clip in position
thereon. The hole (f) shown in Fig. 16 is provided in the clip in order that the
application of a clip such as is shown in Figs. 16 and 17 to a card or plate of a
pattern-card-chain may not interfere with the passage into the hole provided to
receive it in such card or plate, of the appropriate one of the usual nipples or
projections which are provided on the pattern-chain-barrel around which passes the
said pattern-card-chain for the purpose of ensuring that each card or plate shall be
in proper position upon the said pattern-chain-barrel when caused to act upon the
darts or needles of the loom in which such pattern-card-chain is employed.
From the preceding description of the accompanying drawing it will be obvious
that clips made according to my invention may be made of a great variety of forms
as may be convenient, to enable them to be used with pattern-card-chains of
different kinds and that the means by which the clips made according to my
invention may be hindered from being accidentally displaced from the cards or
plates to which they are applied are susceptible of considerable variation, and also
that projections, beadings or turned up portions or other devices of various kinds
may be provided on any suitable parts of such clips to facilitate their removal from
the cards or plates to which they are applied, whenever such. removal may be
necessary or desirable. Clips made according to my invention may be made of any
suitable metal, but must be made sufficiently strong to be able to act upon the darts
or needles in conjunction with which they are used without being readily injured in

page_text: use and in order that they may be sufficiently strong I prefer to make them of
moderately tough steel of suitable thickness and cause such clips to be tempered
so that they may be "sprung" on and off the cards or plates to which they are to
be applied without having their leaves permanently separated.
In order that the use of clips made according to my invention may be more fully
understood I have in front view in Fig. 18 and in transverse section in Fig. 19
shown a card or plate for use in a pattern-card-chain with a clip such as is
illustrated in Figs. 3 and 4 applied thereto. (g) (g) are the holes through which
the nipples or projections which ensure that the card or plate shall when presented
to the darts or needles in conjunction with which it is employed be in proper
position upon the pattern-chain-barrel around which passes the pattern-card-chain
in which such card or plate is employed. (h) (h) are the holes through which pass
the darts or needles which are not to be acted upon by the particular card or plate
when in use of which holes (h) two are shown uncovered in Fig. 18 while the third
of such holes is covered by the clip (A) so that when the said card or plate is
presented to the darts or needles in conjunction with which it is employed the said
clip (A) as it were filling up the said hole will cause the said dart or needle to be
pushed back as though the card or plate were solid or blank at the region of such
card or plate which is presented to such dart or needle. Any required number of
clips made according to my invention may be applied to each of the cards or plates
forming a pattern-card-chain and thus the production of any required pattern may
be arranged for. In order that the clips made according to my invention and
especially those forms which are not provided with projecting beadings or other
devices to facilitate their removal may be removed from the cards or plates more
readily than by the fingers of the person desiring to remove such plates, I would
suggest that use be made of a tool formed of a strip of metal provided at one end
with a portion turned up at right angles to the remainder of such strip and some-
what sharpened and tempered. By the sharpened edge of such a tool being inserted
between one of the clips made according to my invention and the card or plate to
which such clip may be applied, in such manner that the bulges or convexities by
which such clip is held in position are disengaged from the card or plate and by the
person using the tool placing one of his fingers in such position as to hold the clip
upon the said tool while pushing such clip off the card or plate by means of such
tool the said clip may be readily removed from the said card or plate without
danger of being broken or of being pulled or pushed off with a jerk so as to be lost
or to need to be picked up from the floor.
As I have above explained, by the employment of clips according to my invention
in conjunction with such cards or plates as in pattern-card-chains as hitherto
constructed are formed with holes in the parts presented to each needle or dart in
conjunction with which they are employed, I am enabled to readily arrange
pattern-card-chains for the production of any required pattern and also vary the
arrangement of any part of a pattern-card-chain without disconnecting from one
another the cards or plates of which such pattern-card-chain is composed.
Although clips made according to my invention are primarily intended for use in
conjunction with cards or plates formed with a hole in each portion to be presented
to the darts or needles in conjunction with which such cards or plates act, clips
made according to my invention may also be occasionally useful for application to
pattern-card-chains of ordinary kinds in order to cover holes in some of the plates
or cards thereof which it may be desirable to cover in consequence of a mistake
having occurred in the construction of the pattern-card-chain or in order to readily
make some variations in the patterns to be produced by the use of such pattern-
card-chains.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-

page_text: in weaving, clips such as are hereinbefore described, by means of which such cards
or plates may be made capable as and at the places therein which may be requisite,
of moving the darts or needles in conjunction with which they act and made and
employed substantially in the manner and for the purposes hereinbefore described
in reference to and illustrated in and by the accompanying drawing.
2. For use in conjunction with the cards or plates of pattern-card-chains for use
in weaving, clips such as are herein before described, by means of which such cards
or plates may be made capable as and at the places therein which may be requisite,
of moving the darts or needles in conjunction with which they act and are provided
with slight bulges or convexities to secure them in position upon the cards or plates
to which they are applied, and made and employed substantially in the manner and
for the purposes herein before described in reference to and illustrated in and by
Figs. 3 and 4 of the accompanying drawing.
3. For use in conjunction with the cards or plates of pattern-card-chains for use
in weaving, clips such as are hereinbefore described, by means of which such cards

with projecting portions to secure them in position upon the cards or plates to which
they are applied and are made and employed substantially in the manner and for the
purposes hereinbefore described in reference to and illustrated in and by Figs. 5
and 6 of the accompanying drawing.
4. For use in conjunction with the cards or plates of pattern-card-chains for use
in weaving, clips such as are hereinbefore described, by means of which such cards
or plates may be made capable as and at the places therein which may be requisite,
of moving the darts or needles in conjunction with which they act and are provided
with projecting beadings or turned up portions or other devices formed thereon to
facilitate their removal from the cards or plates to which they are applied and made
and employed substantially in the manner and for the purposes herein before
described in reference to and illustrated in and by Figs. 7 and 8 of the accompanying
drawing.
