PROVISIONAL SPECIFICATION.
Improvements in Jacquards used with Looms for Weaving.
. We, JOHN EDWARD WADSWORTH, of Greenside Lane, Droylsden, Lancashire,
Jacquard Machinist, and ARTHUR BEEDILAM, of 18, Hart Street, Droylsden,
Lancashire, Foreman Mechanic, do hereby declare the nature of this invention
to be as follows:-
The improvements relate to jacquards used with looms for weaving, and have
for object the actuation of the wires of such jacquards without the use of the
ordinary spring box mechanisms in manner hereinafter described.
To accomplish this and to effect our improvements, we form each of the hooked
lifting wires of the jacquard with a lengthened loop, so that the lower hooks of
such lifting wires more nearly approach the upper or grife hooks thereof than
is ordinarily the case. The lower hooks are supported by a suitably formed grid
provided with slots at those parts through which the loops of the wires pass.
At a convenient distance below this first named grid we provide a second grid
through which again the loops of the jacquard lifting wires pass.
The neck cords for the healds may be attached to these pendant loops by any
convenient means.
In this manner we are enabled to utilize the spring formed by the looped shape
of the hooked lifting wires as they are held in the grids beforementioned, for
the purpose of bringing the hooks into position with regard to the grifes, instead
of using the ordinary spring box mechanism and to actuate in double lift
jacquards the two lifting wires by one needle.
In order to thus apply this spring of the hooked lifting wires, we form the
needles with a suitable bend at that part where they pass the wires beforenamed,
but in such a way that when such needles are moved in the desired direction they
will abut against one side of the loops of the hooked lifting wires, and press the
same on or off the grifes as the case may be. We allow the ends of the needles
to pass through suitable frames or supports, and the ends of such needles may
be operated upon by cards and card cylinders.
By preference we form that portion of the needles between the wires and the
supporting frame for the needles with another bend or crank, and rest the same
upon a wire or support, in order to counteract the tendency of the needles to twist
or turn.
Variations in detail may be made, such as the precise formation of the hooked
lifting wires, the shape and material of the supporting and guiding grids for the
same, the formation of the supports and guides for the needles and the shape of
such needles, without departing from the peculiar character of the invention.

We, JOHN EDWARD WADSWORTH, of Greenside Lane, Droylsden, Lancashire,
Jacquard Machinist, and ARTHUR BEEDHAM, of 18, Hart Street, Droylsden,
Lancashire, Foreman Mechanic, 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:―
The improvements relate to jacquards used with looms for weaving, and have
for object the actuation of the wires of such jacquards without the use of the
ordinary spring box mechanisms in manner hereinafter described.
:
To accomplish this and to effect our improvements, we form each of the hooked
lifting wires of the jacquard with a lengthened loop, so that the lower hooks of
such lifting wires more nearly approach the upper or grife hooks thereof than
is ordinarily the case.
The lower hooks are supported by a suitably formed grid provided with slots
at those parts through which the loops of the wires pass.
At a convenient distance below this first named grid we provide a second grid
through which again the loops of the jacquard lifting wires pass.
The neck cords for the healds may be attached to these pendant loops by any
convenient means.
In this manner we are enabled to utilise the spring formed by the looped shape
of the hooked lifting wires as they are held in the grids before mentioned, for
the purpose of bringing the hooks into position with regard to the grifes instead
of using the ordinary spring box mechanism, and to actuate in double lift
jacquards the two lifting wires by one needle.
In order to thus apply this spring of the hooked lifting wires, we form the
needles with a suitable bend at that part where they pass the wires beforenamed,
but in such a way that when such needles are moved in the desired direction, they
will abut against one side of the loops of the hooked lifting wires, and press the
same on or off the grifes as the case may be. We allow the ends of the needles
to pass through suitable frames or supports, and the ends of such needles may
be operated upon by cards and card cylinders.
By preference we form that portion of the needles between the wires and the
supporting frame for the needles with another bend or crank, and rest the same
upon a wire or support, in order to counteract the tendency of the needles to twist
or turn.
But that the improvements may be better understood, we will, with the aid of
the accompanying drawings, proceed more fully to describe means employed by
us.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a view in elevation of two sets of jacquard lifting wires, with their
requisite grids in section, arranged in position, and formed in accordance with
our improvements, and Fig. 2 is a plan view thereof with a portion of the upper
grid broken away. Fig. 3 is a plan view showing one end of some needles of the
jacquard, also formed according to our improvements.
The same letters indicate corresponding parts wherever they occur.
a are the lifting wires of the jacquard formed with lengthened loops as at a¹.
The lower hooks of these wires are supported by a grid 6, through which grid
the loops a a pass, openings 61 being provided for the purpose. In order to
ensure more certain action on the part of the lifting wires, the lower hooks thereof

page_text: may be provided with lengthened arms a², which arms pass through openings 63
in the grid b. The loops a, a¹, of the lifting wires, in addition, pass through
openings in the lower grid c.
In Figs. 1 and 2, d shows one needle of each of two rows, provided with the
suitable bends d¹ therein; and these also are provided, by preference, with bends d²
near one end of such needles, as shown in Fig. 3.
For single jacquards each bend d¹ of the needles will actuate a single lifting
wire; whereas in the double jacquard as shown, each bend of the needles will
actuate two lifting wires alternately.
e is a wire or rod at the side of the jacquard, and on which the bent portions d
of the needles rest, and it will be seen that, by this means, the needles d are pre-
vented from turning completely round on their own axes.
When the jacquard is in operation, and when a blank in the jacquard card
comes opposite the end of a needle d in Fig. 1, the latter is moved by the action
of the jacquard cylinder, and abuts against one side of the loop a, a¹, in the lift-
ing wire a by means of the bend d¹ in such needle, and thus moves the upper
hook of such wire away from the lifting grife or knife immediately below it.
These lifting grifes together with other acting parts of the jacquard are not,
however, shown in the drawings.
When the needle d is released, the upper hook of the lifting wire regains its
normal position over the grife by reason of the natural spring formed by the
loop a, a,. When the wire is lifted by the grife, the lengthened arm a² of the
lower hook always remaining in the opening 63 in the grid b, prevents such lower
hook getting out of position on the return of the lifting wire.
Variations in detail may be made, such as the precise formation of the hooked
lifting wires, the shape and material of the supporting and guiding grids for the
same; the formation of the supports and guides for the needles, and the shape
of such needles, without departing from the peculiar character of the invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In jacquards used in looms for weaving, lifting wires formed with lengthened
loop-legs, in combination with needles having bends or cranks therein for actuat-
ing the lifting wires, whether in conjunction with additional bends for counteracting
the tendency of the needles to turn, or not, in manner substantially as herein
shown and described.
