Improvements in Jacquard Apparatus for the Manufacture] of
Carpets and other Woven Fabrics.
I SAMUEL HOLDSWORTH of Henderson House Chester Road Kidderminster
in the County of Worcester Gentleman, do hereby declare the nature of this
invention for Improvements in Jacquard Apparatus for the Manufacture of
Carpets and other Woven Fabrics to be as follows:-
This invention is an improvement on a Patent granted to me the 26th day of
July 1888 No. 10811 and consists in an improved mode of working. the card
cylinder e so that when weaving three frame Brussel carpet or other fabrics of a
like nature one card will do the work of two as used at présent this improvement
is effected by taking out of extra needle plate d every second horizontal row of
short needles e (say) the second fourth sixth and eighth rows.
In perforating cards for this invention the first row of the design is stamped
(say) on the first third fifth and seventh rows in the cards the second row of design
is stamped on the four remaining rows.
The operation of card cylinder is as follows: It advances with the card presses
inst the short needles for the selection of the proper coloured threads to form
the pattern in the usual way, after which it recedes the proper distance but
without making any part of a revolution, the cylinder is then lifted just the
distance that one horizontal row of holes in the cards is from the next, after which
the cylinder with card advances to needles making selection of coloured threads
for second row of design it then récedes in doing which it makes part of a
revolution so as to bring the second card in the series into proper position to
operate needles at the same time the cylinder is lowered to its original position it
then advances with the second card pressing needles as before described so it
continues to operate each card in succession for the whole design.
This invention fürtler consists in an improved method of attaching the extra
face plated to face plate 6 in such a manner that it can be more readily detached
when required to accomplish which I-place on the underside of plate d two centres
which rest in suitable bearings the top of plate d is held in position by catches or
other suitable means.
When the extra face plate is required to be removed the fastenings are released
which allow it to fall forward by so doing the heads of short needles are allowed
sufficient space to clear the points of ordinary needles.

I SAMUEL HOLDSWORTH. of Henderson House, Chester Road, Kidderminster
in the County of Worcester, Gentleman 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 has for its object improvements in Jacquard apparatus for the
manufacture of carpets and other woven fabrics and, is an improvement on the
Patent granted to me on the 26th day of July 1888 and numbered 10811 and
consist of an improved mode of working the card cylinder c. so that when, weaving
three frame Brussel carpet or other fabrics of a like. nature. one card. will do the.
work of two as used. at present this improvement being effected by taking, out of
extra needle plate d every second horizontal row of short needles,e (say) the,
second fourth sixth, and eighth, rows.. In. perforating cards for this invention. the
first row of the, design is stamped (say) on the first, third, fifth.and seventh rows
in the cards the second row of design is stamped on the four remaining, rows.
The operation of card cylinder is as follows, it. advances, with the card, presses.
against the short needles for the selection of the proper coloured threads to form
the pattern in the usual way, after which it recedes the proper distance but without.
making any part of a revolution.the cylinder is then lifted just the distance that
one horizontal row of holes in the cards,is. from the next,, after which the, cylinder
with card advances to needles making selection of coloured threads for second row.
of design, it then; recedes in doing which it makes part of a revolution so as to
bring the second card, in the series into, proper position, to operate, needles at the.
same time the cylinder, is lowered, to its original position in their advance with the.
second card pressing needles, as before described and, so it continues to operate,
each card in succession for, the whole design...
This invention further consists in an improved method of attaching the extra
face plated to face. plate in such a manner that it can be more, readily detached
when required to accomplish which I place on the underside of plate d two centres
which rest in suitable bearings. The top of plate, d is held in position by catches
or other suitable means.
When the extra face plate is required to be removed the fastenings are released
which allow it to fall forward by doing, so the heads of short, needles are allowed
sufficient space to clear the points of ordinary needles
In order that my invention may be clearly understood and more easily carried
into practise I have, appended three, sheets, of, drawings upon which I have
fully illustrated the nature of my various improvements.

The
In carrying my invention into effect the cards are so perforated that the first
row of the design is stamped. say on the first, third, fifth and seventh rows in the
cards, while the second row of design is stamped on the four remaining rows.
card cylinder c is mounted and operated so as to have a rising and falling..
movement its action being as follows
The cylinder advances with the card as shewn by Figure 1 and presses against.
the short needles e for the selection of the proper coloured threads to form the
pattern in the usual way as shewn by Figure 5 after which it recedes the required
distance without making any part of a revolution and is then lifted just the
distance that one horizontal row of holes in the card is from the next as shewn by
Figures 2 and 3 after which the cylinder with card advances to the needles e-
making the selection of coloured threads for the second row of design as shewn
by Figure 6 after which it again recedes in doing which it is caused to make part.-
of a revolution so as to bring the second card in the series into proper position to.
operate the needles and at the same time is lowered to its original position after
which it advances with the second card and presses the needles as shewn by
Figure 5 and so on until each card in succession has been operated to produce the"
whole design.
The mode of and. means for mounting and operating the card cylinder is as
follows. The card cylinder c is mounted upon the sliding rod e' which is operated
by the lever the rod c¹ being so arranged as to have a rising and falling
movement at the cylinder end the plate being slotted out at 6 to allow this
action to take place. The vertical movement of the card cylinder is effected by
means of the vertical sliding bolts p which are provided at each side of the frame
and which are actuated by the stud on the crank lever the latter being
actuated in turn from a suitable cam through the horizontal rod ³ crank lever
and vertical rod a coiled spring being provided to assist the mechanism during
the lowering of the cylinder c and a stop to regulate its travel.
The catches and k¹ are pivotted at k and k and are actuated by the ropes in
the usual way a compensating weight being attached to the other end of the
lower catch by the rope s'. The catches k and are controlled by the lifting-
action before described through the rods or links t and t¹ which are connected
with the crank lever by the rod t and pivotted lever the latter of which is.
operated in one direction by the spring to the fork serves to bring the card
cylinder in its true position and is mounted to slide in the bracket c¹ on the slide c¹
so as to rise & fall with it.
I do not confine myself to the particular mode and details herein described of
raising and lowering the card cylinder as these may be varied considerably
without departing from the nature of my said invention and of course when I
speak of raising and lowering the cylinder I mean a reciprocating movement in a.
direction at right angles or nearly at right angles to the needles to be operated.
I will now proceed to describe my improved attachment of the face plate d to
the face plate b as will be more particularly seen at Figures 7 and 8 by which
means the face plate d can be readily detached and replaced thus assisting the
easy arrangement of the short needles e.
In carrying this into effect 1 form a bearing 6' at the bottom of each end of the
face plate b with a projecting tongue or catch 62 at the top of same and at the
bottom of the face plate d I form two suitable centres d' which fit in the bearing b¹
a corresponding slot fork or other suitable catch arrangement d² being provided
to engage with the tongue or projection 6 with a cotter-pin f for securing the
same in position. It will readily be seen that the plate à may be taken by the

page_text: handles g after the cottars have been withdrawn and allowed to fall forward as
shewn by dotted lines in Figure 8 by which means the heads of the short needles e
are allowed sufficient space to clear the points of the ordinary needles a¹ and the
plated and short needles e may be removed and placed upon suitable brackets
such as a Figure 1 for convenience of alteration of arrangement of needles.
The screw pins 63 are provided to adjust the height of the face plated to a
nicety the bearings d' riding on the nose of the pins 68.
Having now particularly described & 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
