page_text: Improvements in Machinery for Making Warp Lace.
We, WILLIAM DORE of 19 Garfield Cottages, Middleton Street, Radford,
Nottingham, Nottinghamshire, Lace Maker, and JOHN GEE, of 3 Melon Terrace,
Raleigh Street, in the same town, Machinist, do hereby declare the nature of our
said Invention for "IMPROVEMENTS IN MACHINERY FOR MAKING WARP LACE," to
be as follows that is to say:-
This Invention relates to machinery employed for making what is known as
warp lace and it has for its object the novel and improved construction, and
arrangement or combination of parts of such machinery whereby an economy of
material and a lightness of construction is gained whilst the improved machinery
may be worked more conveniently and probably more rapidly than the present
machinery employed for the production of such warp lace.
In carrying out the Invention the beams carrying the threads are arranged to
be carried at the lower part of the machine under the usual steel bars which are
carried at about the middle of the machine and worked by the usual jacquard
apparatus. The usual needles employed in the warp lace machines are carried by
a needle bar in an inclined position above the steel bars with the points or ends of
the needles projecting downwards towards the front of the machine. The usual
pillar bar is carried by arms on a rocking shaft with the ends of the guides just in
front of the needle points. The rocking shaft has a suitable vibratory motion
imparted to it by means of a cam worked from the first motion shaft in a suitable
manner. The point bar is arranged at the back and just under the needles with
the points projecting in a horizontal position towards the front of the machine.
And these points which are of peculiar construction to be hereinafter described
have given to them an alternately rising and falling as well as a to and fro motion,
somewhat similar to the movement of a point bar in a Lever's lace machine. This
motion is indeed obtained by an arrangement of parts similar to that employed in
a Lever's machine, the point bar being fixed at the lower end of a vertical rod
which is centered at its upper end to the end of a nearly horizontally placed lever.
This horizontal lever is centered by its other end to a part of the framing at the
back and has near its middle a truck or anti-friction roller which runs upon a cam
worked by bevil gearing from the first motion shaft. Another truck at the upper
end of a bell crank lever piece presses against the opposite or under side of this
cam and through a rod or arm which is connected to the lower end of the lever

pine is in the improved machine arranged above the needles and the lace is thus
arranged to pass as it is made directly in full view of the worker, up to a take up
roller or beam over head. This is a very important improvement as in most
existing warp lace machines it is difficult if not impossible to see the lace until a
considerable length has been made, consequently as the worker cannot see the lace
as it is forming, a considerable amount of imperfect or defective lace may be formed
before any error is detected. Another important advantage gained by the improved
arrangement or combination of parts of the machinery is that with the improved
arrangement of the point bar and points a gait for gait movement may be taken
and the steel bars may be traversed to their full extent without interfering with
the entering of the points between the divergent threads. This advantage being
partly contributed to by the special form of the points on the point bar. These
points are formed by a series of metal blades fixed each by one end in lead blocks
a short equal distance apart from each other. The outer ends of these blades are
curved to form a point and each pair of blades are brought together so as to touch
at their points so that each pair forms one point. Between each connected pair of
blades forming one point the space is filled in with metal to about half way up the
shanks. This formation of the points is a very convenient one and enables the
machine to be worked at a rapid rate. When the points are brought forward to
take up the work the threads are pressed against the ends of the metal filled in
between the shanks of the points and the needles are at the same time passed
between the pairs of blades forming the points and by the next movement or
shogging of the pillar bar the needles are caused to take up the threads.

We, WILLIAM DORE of 19 Garfield Cottages, Middleton Street, Radford,
Nottingham Nottinghamshire, Lace Maker and JOHN GEE, of 3 Melon Terrace,
Raleigh Street in the same town, 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 :—
Our said Invention relates to the machinery employed for making what is
known as warp lace, and it has for its object the novel and improved construction
and arrangement or combination of parts of such machinery, whereby an economy
of material, and a lightness of construction is gained whilst the improved machinery
may be worked more conveniently than the present machinery employed for the
production of such warp lace.
In carrying out our said Invention the beams carrying the threads are arranged
to be carried at the lower part of the machine under the usual steel bars which
are carried in this case at about the middle of the machine and are worked by the
usual jacquard apparatus. The usual latch needles employed in warp lace machines
are carried by a needle bar so as to be in an inclined position above the steel bars
with the points or ends of the needles projecting downwards towards the front of the
machine. The usual pillar bar is carried by arms on a rocking shaft with the ends
of the guides just in front of the needle points. The rocking shaft has a suitable
vibratory motion imparted to it by means of a can worked from the first motion
shaft in a well known manner. The point bar is arranged at the back and under
the needles with the points projecting in a horizontal position towards the front
of the machine. These points which are of peculiar construction to be hereinafter
described have given to them the well known alternately rising and falling as well
as a to and fro motion, somewhat similar to the movement of a point bar in a
Lever's lace machine. The porcupine in the improved machine is arranged above
the needles, and the lace is arranged to pass as it is made directly in full view of
the worker, up to a take up roller or beam overhead. This is a very important
advantage as in most existing warp lace machines it is difficult if not impossible to
see the fabric until a considerable length has been made consequently as the worker
cannot see the lace as it is forming a considerable amount of imperfect or defective
lace may be formed before any error is detected. Another important advantage
gained by the improved arrangement or combination of parts of the machinery.is
that with the improved arrangement of the point bar and points a gait for gait
movement may be taken and the steel bars may be traversed to their full extent
without interfering with the entering of the points between the divergent threads,
this advantage being partly contributed to by the special form of the points on the
point bar. These points are formed by a series of metal blades fixed each by one
end in lead blocks a short equal distance apart from each other. The outer end of
these blades are curved to form a point and each pair of blades are brought
together so as to touch at their points so that each pair of blades forms one point.
Between such connected pair of blades forming one point the space is filled in with
metal so as to be solid to about half way up the shanks from the fixed ends and

page_text: these solid parts are bevilled on the upper side. This formation of the points is
an important and very convenient one and enables the machine to be worked at a
comparatively rapid rate. When the points are brought forward to take up the
work the threads are pressed against the ends of the metal between the shanks of
the points and the needles are at the same time passed between the pairs of blades
forming each point and on the next movement or "shogging" of the pillar bar the
needles are caused to take up the threads as the points carrying them are with-
drawn backwards. The needles slipping easily through the touching ends of the
pair of curved blades forming each point and thus taking up the assorted threads.
And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing our improved arrangements and
construction of parts of apparatus forming a warp lace machine. In these drawings
the same reference numerals are used to mark the same or like parts wherever they
are repeated.
Figure, 1, on the accompanying sheet of drawings is a transverse section of part of
our improved warp lace machine, showing only sufficient of the machine as is required
to enable this Invention to be understood. It will be understood that such parts
of the machine as are not shown or described may be of any well known kind
constructed and arranged conveniently in any well known manner. The needles, 1,
in our improved machine are preferably carried so as to work in an inclined
position with their points downwards with the hooks and latches underneath and
are carried in the usual way in lead blocks which are suitably secured to a needle
bar, 2. This needle bar, 2, has the ordinary well known movement communicated
to it by means of an eccentric or cam or by other well known means. In front of
the needles, 1, there is arranged the ordinary pillar bar, 3, carrying the usual
guides, 4, which are carried with their ends pointing up towards the needles in a
suitable manner. The pillar bar, 3, has its well known movement communicated
to it by the usual arrangement of a rocking shaft levers and cam, with its endwise
movement also given in the usual way. The needle bar and point bar are carried
preferably at about the middle of the machine and the steel bars, 7, for carrying
the figuring threads are arranged a convenient distance below being carried
and operated in a well known manner. Underneath the needles, 1, there is
arranged a point bar, 5, to which the well known alternately rising and falling as
well as a to and fro motion is preferably given by means of a well known arrange-
ment of levers, rods and cam, similar to the arrangement for giving motion to the
point bar of a Lever's lace machine. These points, 6, on the point bar, 5, are fitted
in lead blocks in an ordinary manner and carried by the point bar, and are of
special construction. The points, 6, are formed by arranging a short distance
apart a number of thin metal blades (see figure, 2, which is a full sized side view
of these points, whilst figure, 3, is a plan of a set of them. These blades are bent
at their ends so that each pair of blades touches each other only at the ends and
so form a point, and between each of these points metal is filled in so as to make
them solid between their shanks to about half the distance between their ends and
the lead block carrying them. These solid parts between the points formed by
each pair of blades are each bevilled on each side at the upper side of the points,
and will be best seen in figure, 3, at A―A. This formation of the points with
solid parts extending half up the shanks of the points and the bevilling of the
upper side of these solid parts is of great importance and facilitates the entry of
the needles between the blades forming each point, it being quite impossible for a
needle through being slightly bent or other cause, entering into the wrong place
as the bevilled parts will assist in guiding the needle into its proper place. The
needles are caused to enter between the blades forming points as herein described
whenever the point bar, 5, having made a selection of threads arranged by the
steel bars is brought up by the well known motion given to it to the needles.
When the points, 6, are brought up to the needles, 1, the assorted threads lie
between the points against the solid part and are thus kept about half way up the

page_text: shanks of the points. This enables the needles which are next moved downwards
to enter at the back as it were of the threads and between the bevilled parts of
the points. On the next movement of the points backwards the needles slip
through the bent touching ends of the blades forming points, and the threads are
thus transferred from the points to the needles being fastened in a well known
manner by the action of the pillar bar. The fabric produced on the machine is
led upwards in full view of the worker to the "porcupine" arranged on the
framing above, thence to a take up roller or beam overhead. With the foregoing
arrangement of the working parts of a warp lace machine the beams or rollers
carrying the warp threads are placed at the lower part of the machine and the
arrangements admit of a considerably greater number of steel bars being used than
is possible with most existing warp lace machines. The foregoing arrangements
also admit of a gait for gait movement being taken and the steel bars may be
traversed to their full extent without interfering with the entering of the points
between the divergent threads, this advantage being partly contributed to by the
special formation of the points as hereinbefore described.
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
(1.) The combination and arrangement of a point bar (5) having specially
formed points (6) with an inclined needle bar (2) a pillar bar (3) and fancy thread
steel bars (7) operating substantially as and for the purposes herein before described
with reference to the accompanying drawings.
(2.) The forming of spring blade points (6) with solid parts between them which
are bevilled on the upper side substantially as and for the purposes hereinbefore
described with reference to the accompanying drawings.
