Improvements in Machines for Lacing Together Jacquard and other
Cards for Weaving.
We, CHARLES HAHLO and CHARLES EDWARD LIEBREICH, of Mill Street,
Bradford, in the County of York, Machine Makers, and THEOPHILUS HANSON
of the same place, Machinist, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is the construction of a machine by a novel com-
bination of parts so arranged that, the mechanism is simplified, and the operation
of lacing effected in a more direct manner with the cords in sight of the
operator.
We accomplish our object in the following manner. Upon a suitable frame is
mounted a table supporting a number of brackets, each carrying a hollow spindle
provided with a flange at one end, to the face of which are secured two eyes.
Below the tables are two treadles and levers, the latter are connected by a
flexible strap, such as leather, which passes over pullies secured on the before
mentioned hollow shafts, so that on the operation of the treadles, the hollow shafts
are rotated.
Each card as it is to be connected, is placed upon a cylinder and between two
cords, one or both of which pass through each hollow shaft and eyes. They are
then turned by the operation of the treadles an entire or some portion of a
revolution, by which the cords are twisted around the cards. The cylinder is
then automatically turned the required distance by suitable connections with
the treadles ready for the reception of another card when the operation is
repeated.

Improvements in Machines for Lacing Together Jacquard and other
Cards for Weaving.
We, CHARLES HAHLO and CHARLES EDWARD LIEBREICH of Mill Street,
Bradford, in the County of York, Machine Makers, and THEOPHILUS HANSON, of
the same place, Machinist, 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 certain improvements in machines for lacing together
Jacquard and other cards for weaving, and has for its object, the construction of a
machine by a novel combination of parts so arranged that, the mechanism is
simplified, and the operation of lacing effected in a more direct manner with the
cords in sight of the operator.

page_text: In order that our invention may be fully understood, we will describe the
same in detail by making reference to the accompanying sheet of drawings, in
which
and
Fig. 1 represents a side view of our improved machine.
Fig. 2 is a front view of same.
Fig. 3 is, an enlarged detail of a flanged hollow spindle for twisting the cords,
Fig. 4 a sectional view of some Jacquard cards as laced by our improved
mechanism.
Upon a suitable frame A. we mount a table B. supporting the brackets C. each
of which carries a hollow spindle D. provided with a flange D' at one end, to the
face of which are secured in any convenient manner the eyes E. E.
Below the table B. mounted in any convenient manner are the treadle levers F.
and F connected by rods G. and G₁ to the respective levers H. and H' mounted to
brackets J. and J' secured to the frame A. of the machine, the levers H. and H¹
are connected together by a flexible strap of leather or the like K. passing over
pullies L. which may be provided with pegs or studs L' and secured on the before
mentioned hollow spindles D. so that on the operation of the treadle levers F. and F
the hollow spindles D. are rotated, first in one direction and then in the other.
The flexible belt K. may be passed under guide pullies L' somewhat as shown on
drawings.
The before mentioned levers H. and H¹ are reduced at one end, and engage in
the slot of the respective links M. and M' in a manner that, on the downward
movement of the said levers, the respective links are operated; the latter are
secured to one end of the respective levers N. and N¹ which are attached to the
cross shaft O. mounted on brackets O'. The opposite ends of the said levers N.
and N are connected to the spiral springs P. and P₁ attached to frame A.
To the lever N. is secured a pawl Q. engaging with the pawl wheel Q¹ secured
on shaft R. supporting an ordinary card cylinder S. whereby on the stroke of each
treadle lever F. or Fi the said cylinder is turned one fourth of a revolution or in
accordance with the number of teeth in pawl wheel Q' and sides on the card
cylinder.
The cords T. for lacing the cards are placed in a suitable receptacle U. and
passed between the tension bars V. one of which is fixed and the other moveable
and supported by arms V' and suitable brackets V. The cords then pass between
the guide pullies W. and through the hollow spindles D. to the before mentioned
eyes E. E. The card X. to be connected or laced to the others is placed between
the cords T. as shewn in Fig. 1, whereupon, on the operation of one of the treadle
levers F. or F the hollow spindles D. and Hanges D₁are turned an entire or some
portion of a revolution, by which each pair of cords T. are twisted at the point Y.
thus securing the card X. The ordinary card cylinder S. is then automatically
turned in the manner as herein before described the required distance, ready for the
reception of another card X. when the operation is repeated:
The cords T. are held tight between the bars V. during the twisting of the cords
around each card and are liberated when the card cylinder S. operated, the
alternate securing of the cords between the said tension bars V. is accomplished by
the oscillation of the lever Z. secured on shaft O. and connected by rod Z¹ to one
of the said tension bars in a manner that the said bar is moved towards and away
from the other bar which is fixed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is,
1. An apparatus by which Jacquard and similar cards X. are secured together
by the twisting of cords T. around same, substantially in the manner as shown and
described

page_text: 2. The combination of the treadle levers F. and F' with the hollow spindles D.
and intermediary connections, arranged substantially in the manner and for the
purpose shown and hereinbefore described.
3. The combination of the shaft O. and lever Z. with the fixed and moveable
tension bars V. arranged substantially in the manner and for the purpose as
hereinbefore described and shown in the drawings.
