Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer do hereby declare the nature of this invention to be as follows:-
In existing Jacquard mechanisms the pattern card causes a number of the wires
to be locked with the lifting blade, which forms the upper shed, and the rest with
that formning the lower shed. This occurs chiefly from the fact that every wire is
capable of assuming two possible positions in each of which it is locked with another
lifting blade. The wires are caused to assume these positions either directly by the
thrust of the card needles, or indirectly by reason of the card needles remaining
inoperative, or the card needles may operate certain intermediate mechanisms in such a
manner that the latter either directly take up such positions as to occasion the locking
of the wires with one lifting blade or the other, or the wires are first placed in such
a position as to allow of the co-operation of further mechanisms acting independently
of the card cylinder. This mode of procedure may be compared to the releasing of

case an accumulated force is given out for the work. In the former case a force
suffices, which is imparted to the arrangement at each repeated thrust, and in a given
manner as required.
The novelty in this arrangement is that such a disengagement occurs twice. It
becomes possible by this means to construct the first disengaging mechanism, which is
acted upon directly by the card cylinder, very narrow and weak so that a very small
cylinder may be employed. Furthermore the double disengaging apparatus is easily

page_text: accommodated to the modifications of the apparatus necessary for vertical or
horizontal warps.
The card cylinder turns as usual in its to and fro movements at each thrust. It,
thereby either drives upwards or leaves stationary a row of vertical needles. When
driven upwards, these needles lift slightly the ends of a row of horizontal stickers
arranged in a vertical plane. Immediately after each oscillation of the card cylinder,
a lever imparts a longitudinal thrust to the stickers if their ends have been raised, but
it leaves them inoperative if their ends have not been raised. The swinging lever is
perforated in such a manner that the sticker ends which remain stationary can pass
through undisturbed while those that have been raised are pushed forward by the
bridges left between the perforations. The stickers that are pushed come in contact
at their opposite extremities with a double hooked wire. The latter is spring-pivoted
upon the wire or leaf bar, which moves in a fixed path. In the position of rest, the
spring presses this hook sideways beyond the edge of the said wire or bar, so that the
lifting blade which forms the lower (hinder) shed, catches it and takes the wire with it;
but if the sticker presses the second hook of the wire hook on to its spring and out
beyond the other side of the leaf bar, then the lifting blade for forming the upper
(front) shed catches it. The return of the leaf bars is accomplished by the action of
two other lifting blades, which after each movement of the said bar, move from either
side towards the centre, and thus bring back the leaf bars with their hooks by means
of a fixed tappet upon each bar. In forming sheds, these blades must be again
separated so that the tappets are somewhat hastened, and the bars are not hindered
in their motion through this second pair of blades; these requirements can be
satisfied if the movement of each pair of blades is made to correspond with that of a
crank chain.
The movements of the new working parts may now he described, and then the way
of applying these movements to those mechanisms which do not form a portion of
the invention, but only serve to completely and clearly explain the invention.
The card cylinder moves vertically up and down, and with each swing makes a
quarter turn so as to traverse the card chain further. When the cylinder reaches
the highest point, the card with its unpierced part lifts up some of the needles
aforesaid. Each of these neeilles has on one side an eye through which a sticker is
inserted. Both the stickers and needles are loosely fixed in bearings in the
framework, and the stickers have so much play that the raising of them by means of
the eyes of the needles is rendered possible."
When the raising of these aforesaid stickers is completed the flat arm of the
elbowed lever aforesaid, strikes the ends of the stickers that are raised, while those
that are not operated come opposite to the perforated portions of the flat striking
arm, through which they pass without undergoing any change of position. In front
of the opposite ends of the stickers (which are arranged in a vertical plane) is a
row of horizontal leaf bars, also arranged one above the other in a vertical plane (if a
vertical warp is used).
1
Each leaf bar is moved in an accurate horizontal path and carries a double hooked
wire as aforesaid, which is pressed by a spring against the point of a sticker, and if
the latter is not struck by the lever arm, the spring presses it and the hooked wire
back. In this position, one of the hooks stands out on one side of the leaf bar and by
it the said bar is drawn into the hinder shed through the medium of one of the
lifting blades. But if the sticker is driven against the hooked wire by the lever arm,
so that the pressure of the spring is overcome, the other hook projects beyond the side
cof the leaf bar, and the lifting blade presses the said bar into the front shed. The
1.acute angled mouth of the two hooks allows the return of the stickers after the
resultant contact without disengaging the leaf bar and the lifting blade.
This disengagement does not occur till the blade commences to return. The return
of the leaf bars is effected through tappets on the same, with which a second pair of
ilifting blades engages and brings the bars back to their meau position. In each case
a blade for driving up (forward) is joined to one for driving down (backward) by a
link and they are connected to a crank apparatus. Since the blades for returning

page_text: the leaf bars swing through a somewhat greater angle than those which operate the
bars it results from the laws of crank motion that in forming the sheds on one side
or the other, the releasing blades pass slightly ahead of the tappet aforesaid, and thus
do not obstruct the free movement of the leaf bars. The blades return after a slight
pause and the connection of the hooks and the blades is broken. The releasing
blades then strike the tappets and drive the bars back to their original position. The
blades, striking lever and card cylinder may be worked by means of levers, links,
or chains from a suitable point or points on the ordinary loom. This part of the
apparatus will be described at greater length in the complete specification.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
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
-
In existing Jacquard mechanisms the pattern card causes a number of the wires
to be locked with the lifting blade, which forms the upper shed, and the rest with
that forming the lower shed. This occurs chiefly from the fact that every wire is
capable of assuming two possible positions in each of which it is locked with a
different lifting blade. The wires are caused to assume these positions either
directly by the thrust of the card needles, or indirectly by reason of the card
needles remaining inoperative, or the card needles may operate certain intermediate
mechanisms in such a manner that the latter either directly take up such positions
as to occasion the locking of the wires with one lifting blade or the other, or the
needles may be first placed in such a position as to allow of the co-operation of
further mechanisms acting independently of the card cylinder. This mode of
procedure may be compared to the releasing of accumulated work by means of a
comparatively very small power. In the latter case an accumulated force is given
out for the work. In the former case a force suffices, which is imparted to the
arrangement at each repeated thrust, and in a given manner as required.
The novelty in this arrangement is that such a disengagement occurs twice. It
becomes possible by this means to construct the first disengaging mechanism,
which is acted upon directly by the card cylinder, very narrow and weak so that
a very small cylinder may be employed. Moreover the double disengaging
apparatus is easily accommodated to the modifications of the apparatus necessary for
vertical or horizontal warps.
The card cylinder turns as usual in its to-and-fro movements at each thrust. It,
thereby, either drives upwards or leaves stationary a row of vertical needles. When
driven upwards, these needles lift slightly the ends of a row of horizontal stickers
arranged in a vertical plane. Immediately after each oscillation of the card cylinder,
a swinging elbow lever imparts a longitudinal thrust to the stickers if their ends
have been raised, but it leaves them inoperative if their ends have not been raised.
The swinging elbow lever is perforated in such a manner that the sticker ends which
remain stationary can pass through undisturbed, while those that have been raised are

page_text: pushed forward by the bridges left between the perforations. The stickers that are
pushed come in contact at their opposite extremities with a double hooked wire.
The latter is spring-pivoted upon the wire or leaf bar, which moves in a fixed path.
In the position of rest, the spring presses this hook sideways beyond the edge of
the said leaf bar, so that the lifting blade which forms the lower (hinder) shed,
catches it and takes the leaf bar with it, but if the sticker presses the second hook
of the double wire hook against its spring and out beyond the other side of the leaf
bar, then the lifting blade for forming the upper (front) shed catches it. The
return of the leaf bars is accomplished by the action of two other lifting blades, which
after each movement of the said bar, move from either side towards the centre, and
thus bring back the leaf bars with their hooks by means of a fixed tappet upon each
bar. In forming the sheds these blades must be again separated so that their return
is somewhat hastened, and the bars are not hindered in their motion by this second
pair of blades, these requirements can be satisfied if the movement of each pair of
blades is made to correspond with that of a warp crank (Kurbelkette).
In the accompanying drawings,
Figures 1 and 2 show two views of this mechanism, in which, at the points where
the driving rods of the loom engage, the direction of motion is indicated by
arrows.
Figure 3 and also Figure 2 show the two pairs of lifting blades and their mode
of connection, and also the connection of the card cylinders with the needles and
stickers.
Figures 4 and 5 show wires with double hooks in their two different positions.
Figure 6 shows a leaf bar connected to the heald which it serves to operate.
The remaining Figures will be hereinafter described.
The movements of the new working parts may now be described, and then the way
of applying these movements to those mechanisms which do not form a portion of the
invention, but only serve to completely and clearly explain the invention.
wo is the card cylinder which moves vertically up and down, and with each swing
makes a quarter turn so as to traverse the card chain further. When the cylinder w
reaches the highest point, the card with its unpierced part lifts, up some of the
needles aforesaid. Each of these needles has on one side an eye o through which
a sticker e is inserted. Both the stickers e and needles f are loosely fixed in bearings
in the framework and the stickers have so much play that the raising of them by
means of the eyes o of the needles fis rendered possible.
When the raising of these aforesaid stickers e is completed, the flat arm of the
elbow lever aforesaid, strikes the ends of the stickers e that are raised, while
those that are not operated come opposite to the perforated portions of the lever i
(see Figures 1 and 3) through which they pass without undergoing any change of
position. In front of the opposite ends of the stickers e (which are arranged in a
vertical plane) is a row of horizontal leaf bars a, also arranged one above the other in
a vertical plane (if a vertical warp is used).
e,
Each leaf bar a is moved in an accurate horizontal path and carries a double
hooked wire as aforesaid, which is pressed by a spring b against the point of a
sticker and if the latter is not struck by the elbow lever i, the spring presses it and
the hooked wire back (as seen in Figure 4). In this position, one of the hooks H¹
stands out on one side of the leaf bar, a, and by it the said bar is drawn along
through the medium of one of the lifting blades c so as to form the front shed. But
if the sticker e be driven against the hooked wire by the elbow lever i so that the
pressure of the hook spring is overcome, the other hook H* projects beyond the side
of the leaf bar (as seen in Figure 5), and the other lifting blade c¹, presses the said
bar along so as to form the hinder shed. The acute angled mouth of the two
hooks H Hallows of the return of the stickers e after contact with the hooks without
disengagement of the leaf bars and the lifting blade taking place.
The

return of the leaf bars is effected through tappets Z-on the same, with which a second
pair of lifting blades d d engages and brings the bars back to their normal

page_text: position. It may be seen from the drawings that in each case a blade for driving up
(forward) is joined to one for driving down (backward) by a link, and they are
connected to a crank apparatus. Since the blades d d for returning the leaf bars a
swing through a somewhat greater angle than those which operate the bars, it results
from the laws of crank motion that in forming the sheds on one side or the other,
the releasing blades d d¹ pass slightly ahead of the tappets Z aforesaid, and thus do
not obstruct the free movement of the leaf bars. The blades d d¹ return after a slight
pause and the connection of the hooks H¹ H2 and the blades c c¹ is broken. The
releasing blades d d¹ then strike the tappets Z and drive the bars back to their
original position.
Figures 7 and 8 show the application of the crank apparatus to a loom with
vertical warp. The invention may be applied to a weaving loom with a vertical warp,
as follows.
The warp beam and the cloth beam are carried by suitable brackets D D attached
to the framing A near the top and bottom respectively. The main shaft H is also
carried in suitable bearings on the frame A and is rotated by its crank G through the
medium of a treadle F or its equivalent. Three grooved cams M N O upon the main
shaft engage the forward ends of three horizontal levers K L Q and impart to their
opposite or rear ends an oscillating movement in a vertical plane. The rear end of
one of these levers K imparts its motion to the lifting blades cc by means of suitable
rods S and T. The rear end of the second lever L is connected by a rod V to the
elbow lever i aforesaid, and imparts a swinging motion thereto, and the rear end
of the third lever Q produces, by means of a suitable connecting rod R, the to-and-fro
motion of the card cylinder.
The Jacquard mechanism thus driven communicates its motion in the manner
described to the leaf bars a which is immediately communicated to the healds.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is-
1. In a Jacquard loom, a shed forming mechanism in which the leaf bars are
operated in each direction by two lifting blades e c¹, moving in opposite directions,
the requisite engagement being brought about through the medium of a doublé
hook b on each leaf bar, the said hook being held normally by a spring beyond one
side of the leaf bar so as to be engaged by one lifting blade c, and being pressed
beyond the opposite side of the bar so as to be engaged by the other lifting
blade c through the operation of a sticker which is actuated by a striking elbow
lever after being placed (or left) in position by the indirect action of the card cylinder,
substantially as described.
2. In a Jacquard loom having each leaf bar provided with a double spring hook
such as for the purposes described, a sticker e adapted to press said hook aside
with its front end whenever its rear end is engaged by a slotted striking lever i,
such engagement being brought about whenever the rear end of the sticker is lifted
(or left stationary) by a needle f which is operated directly by the thrust of the card
cylinder, substantially as described and shown.
3. The herein described improvements in Jacquard mechanism, by means of which
a symmetrical opening or closing of the shed is obtained with small wear and tear of
the pattern card.
