Improvements in Apparatus for Connecting or Lacing" the Cards
used in Looms for Weaving, and Improved Cards used in Cön-
nection therewith.
[
I, JOHN WILKINSON, of Laurel Bank Mill, Nelson, in the County of Lancaster,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved apparatus to be employed for connecting, or
lacing" together the cards used in looms for weaving whether such cards are con-
structed of steel, paper, or wood, such as in Jacquard machines, and by the use, of this
invention I obviate the necessity of having to pass the laces or cords twice through
each one of the "eyes" formed in the cards, and also with the use of needles which
had heretofore to be employed.
According to this my said invention an ordinary card cylinder is mounted on an
arm fixed to any convenient part of a frame constructed to carry the several parts of
the apparatus the cylinder is caused to revolve by means of a treadle, and finger, the
latter, when the treadle is depressed turning the cylinder one tooth of a ratchet wheel
or part of a revolution.
A spiral spring draws the finger down again and the treadle into position when the
pressure is removed. Opposite the cylinder and mounted in the frame are two, two-
pronged forks, each prong terminating in an eye the other ends or stems of the forks,
toothed
are geared together by means of two pinion wheels, driven by means of a
wheel which is operated and turned part of a revolution by means of a
treadle, and
when the pressure is taken off the latter a spiral spring attached to the other side
of the wheel, turns the latter part of a revolution in the reverse direction, and gearing
with one of the pinions above mentioned, revolves the same and the forks, first in
one direction and then in the opposite one.
Bobbins for carrying the cords or laces are held on the frame, the cords or laces
passing therefrom under, and over guides to the two pinions above mentioned the
axes of which are hollow, and through which two cords or laces pass and are, carried
one through each of the four eyes in the forks thence to the cards which are placed on
the cylinder as required and held in position, until secured by the cords or laces, by
means of a blade spring, the cylinder is for the purpose of carrying the cards and
ensuring equal and correct space between them.
The cards in lieu of having holes punched through them, or rings attached thereto
as formerly for the passage of the laces or cords have two notches formed in each, side
and near the ends so that the cords or laces are prevented from slipping off the cards.
The cords or laces are placed one over and one under at each ends of the cards the
treadle operating the gear wheel is then depressed and the pinions are operated turning
the forks which give one twist to the cords or laces (i.e. the cords or laces at each end
of the cards are crossed) another card is then placed in position when the spring
turns the wheel in the reverse direction and a similar action of the cords or, laces
takes place, the cylinder being revolved by uieans of the treadle first herein
mentioned.
By the use of the above described apparatus great saving of time is effected, and
consequently cards are laced, or connected at much less cost.

Improvements in Apparatus for Connecting or
Lacing" the Cards
used in Looms for Weaving, and Improved Cards used in Con-
nection therewith.
I, JOHN WILKINSON, of Laurel Bank Mill, Nelson, in the County of Lancaster,
Manufacturer, 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 :-
This invention relates to improved apparatus to be employed for connecting, or
"lacing" together the cards used in looms for weaving whether such cards are con-
structed of steel, paper, or wood, such as in Jacquard machines, and by the use of
this invention I obviate the necessity of having to pass the laces or cords twice through
each one of the "eyes" formed in the cards, and also with the use of needles which
had heretofore to be employed.
According to this my said invention an ordinary card cylinder is mounted on an
arm fixed to any convenient part of a frame constructed to carry the several parts of
the apparatus the cylinder is caused to revolve by means of a treadle, and finger, the
latter, when the treadle is depressed turning the cylinder one tooth of a ratchet wheel
or part of a revolution.
A spiral spring draws the finger down again and the treadle into position when the
pressure is removed. Opposite the cylinder and mounted in the frame are two, two
pronged forks, each prong terminating in an eye the other ends or stems of the forks
are geared together by means of two pinion wheels, driven by means of a toothed
wheel which is operated and turned part of a revolution by means of a treadle, and
when the pressure is taken off the latter a spiral spring attached to the other side of
the wheel, turns the latter part of a revolution in the reverse direction, and gearing
with one of the pinions above mentioned, revolves the same and the forks, first in one
direction and then in the opposite one.
Bobbins for carrying the cords or laces are held on the frame, the cords or laces
passing therefrom under, and over guides to the two pinions above mentioned the
axes of which are hollow and through which two cords or laces pass and are carried
one through each of the four eyes in the forks thence to the cards which are placed
on the cylinder as required and held in position, until secured by the cords or laces,
by means of a blade spring, the cylinder is for the purpose of carrying the cards and
ensuring equal and correct space between them.
The cards in lieu of having holes punched through them, or rings attached thereto
as formerly for the passage of the laces or cords have two notches formed in each side
and near the ends so that the cords or laces are prevented from slipping off the
cards.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the accompanying drawings in
which-
Fig. 1 is an end or side elevation of my improved apparatus for connecting, or
lacing" together the cards use in looms for weaving.
Fig. 2 is a front elevation of same.
Fig. 3 is a plan view of cards, laces or cords and two pronged forks, shewing how
the cards are connected or laced together.
Fig. 4 is a detail shewing end view of cylinder, cards, and laces or cords.
According to this my said invention an ordinary card cylinder 1 is mounted on an
arm 2 fixed to any convenient part of a frame 3 constructed to carry the several parts
of the apparatus. The cylinder 1 is caused to revolve by means of a treadle 4 rod 5
and finger 6, the latter, when the treadle 4 is depressed turning the cylinder, one
tooth of a ratchet wheel 7 or a part of a revolution. A spiral spring 8 draws the

page_text: rod 5 and finger down again and the treadle 4 into position when the pressure is
removed. Opposite the cylinder 1. and mounted in the frame 3 are two, two-pronged
forks 9, 10, each prong terminating in an eye 11 the other ends or steins 12 of the
forks 9, 10 are geared together by means of two pinion wheels, 18, 14 fixed on
the stems 12 and driven by means of a toothed wheel 15 which is operated and turned
part of a revolution in one direction by means of a treadle 16 and rod 17 its upper
end being attached to one arm of the wheel 15 and when the pressure is taken off
the treadle 16 a spiral spring 18 attached to one arm or to the face and at the other
side of the wheel 15, i.e. opposite to where the rod 17 is attached to it (see Fig. 2)
turns the wheel 15 part of a revolution in the reverse direction, and gearing with one
of the pinions 14 above mentioned revolves the same and also the forks 9. 10 first in
one direction and then in the opposite one.
Bobbins 19 for carrying the cords or laces 20. 20 are carried on a stand or on the
frame, the cords or laces 20 passing therefrom under, and over guides and tension
bars 21. 21 to the two pinions 13. 14 above mentioned the axes 22. 22 of which are
hollow, and through which two cords or laces 20. 20 pass and are carried one through
each of the four eyes 11. 11 in the forks 9. 10 thence to the cards 23 which are
placed on the cylinder 1. as required and held in position on the cylinder 1 until
secured by the cords or laces 20. 20 by means of a blade spring 24 and the ordinary
studs or pins 25. 25, the cylinder 1 is for the purpose of carrying the cards 23 and
ensuring equal and correct space between them when fixed together.
The cards 23 in lieu of having holes punched through them, or rings attached
thereto as heretofore for the passage of the laces or cords have two notches 26. 26
formed in each side and near the ends so that the cords or laces 20. 20 are prevented
from slipping off the cards 23. The cords or laces 20. 20 are placed one over and
one under at each end of the cards 23 the treadle 16 operating the gear wheel 15, is
then depressed and the pinions 13. 14 are operated turning the forks 9. 10 which give
one, two or more twists as desired to the cords or laces 20. 20 (ie. the cords or
laces 20. 20 at each end of the cards 23 are crossed) another card 23 is then placed
in position between the cords or laces 20. 20 and on the succeeding flat surface 30
(see Fig. 4) of the cylinder 1 which is then turned by the treadle 4 rod and finger 6
so as to bring the card 23 under the holding spring 24 whereon the pressure is with-
drawn from the treadle 16 and the spring 18 turns the wheel 15 in the reverse
direction and a similar action of the cords or laces 20. 20 takes place. The first and
last cards to be laced are tied by hand to prevent the cords or "laces" 20. 20
becoming untwisted.
Collars 27. 27 are placed on the rods 5 and 17 one at each side of the rails 28 29
through which the rods 5. 17 respectively work, these collars acting as stop pieces
prevent the cylinder 1 and wheel 15 being turned too far, and in the case of the
latter if more than one twist to the cords or laces 20. 20 is required to be given
between each card 23 the collars 27 are moved further apart, so that the wheel 15
has a greater amount of motion imparted to it, and consequently to the pinion 13, 14,
and forks 9. 10.
In the drawings annexed I have shown the apparatus as operated by manual power,
but it will be obvious the same could be worked by power employing a can or tappet
to depress the treadle 4, 16 or draw down the rods 5. 17 at regular intervals.
By the use of the above described apparatus great saving of time is effected, and
consequently cards are laced or connected together at much less cost.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed, I declare that
what I claim is :-
1. The method of, and means employed for lacing or connecting cards used in looms
for weaving substantially as herein described and as illustrated by the accompanying
drawings.
