PROVISIONAL SPECIFICATION.
Improvements in Warp Lace Machines and the like.
I, BERNARD BUXTON SMEDLEY, of Lawrence Street, Sandiacre, in the County
of Derby, Lace Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in warp lace machines and the like, and
is designed to provide a machine in which are combined most or all the advantages
and facilities for manufacturing lace which are obtained by the warp lace machinery
at present in use, and by the Levers lace machine.
For the purpose of this invention, the pillar thread in a warp lace machine, or
the like, is carried among or taken up with the thick or warp threads, and the
work, or finished lace, is conducted underneath the needles and below the needle
bar to the roller or beam for receiving the finished work. Any desired number of
warp threads, or threads from the perforated steel bars, may be employed, and the
pillar thread, instead of being limited in length like the bobbin or carriage thread
in a Levers machine, can be of any desired length.
In order to carry my invention into effect, I employ points or devices, of
approximately triangular shape, formed preferably of sheet metal, and carried in
leads upon a suitable bar. Said triangular points or devices have a slot preferably
of elliptical shape inclined from the lower angle or corner upwards, and of such
dimensions that during the movement of the said points or devices, which take the
threads from the perforated steel bars, and also the pillar threads, they shall not
interfere with or strain the said warp and pillar threads. The moving needle bar
which carries the needles is supported above the level of the needles in a suitable
mauner, preferably between the tricks and the roller or beam for the net or
material.
The triangular points or devices work below the needles and take the warp or
threads from the perforated steel bars and also the pillar threads, and lap the pillar
thread by means of the ordinary point above the needles, said point having an up
and down and also a lateral motion, but not of the same extent as in machines as at
present constructed. The triangular point or device takes the pillar thread
forward and above the needle, said pillar thread is lapped underneath by the said
ordinary point, and puts itself on the top of the needles in the downward
movement. The slot in the triangular point or device, through which the pillar
thread passes, draws the pillar thread with it to lift it above the needle, but during
the rest of the movement of the said triangular point the pillar thread unaffected.
The triangular points are carried upon a bar, suitably arranged at a sufficient
distance below the needle bar not to interfere with the passage of the finished lace
to the roller.
Lace designs hitherto made only on Levers' machines can be made on a warp
machine constructed according to my invention; and such formerly made on warp
machines can be produced in greater variety.

I, BERNARD BUXTON SMEDLEY of Lawrence Street, Sandiacre, in the County
of Derby, Lace Maker, 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, reference being had to the accom-
panying drawings and to the letters and figures marked thereon, that is to say :-
This invention relates to improvements in warp lace machines, and the like, and
is designed to provide a machine in which are combined most or all the advantages
and facilities for manufacturing lace which are obtained by the warp lace machinery
at present in use, and by the Levers lace machine.
For the purpose of this invention, the pillar thread in a warp lace machine or
the like is carried among or taken up with the thick or warp threads, and the work
or finished lace is conducted underneath the needles and below the needle bar, to
the roller or beam for receiving the finished work. Any desired number of warp
threads, or threads from the perforated steel bars, may he employed, and the pillar
thread, instead of being limited in length like the bobbin or carriage thread in a
Levers niachine, can be of any desired length.
In order to carry my invention into effect, I employ points or devices of
approximately triangular shape, formed preferably of sheet metal and carried in
leads upon a suitable bar. Said triangular points or devices have a slot, preferably
of elliptical shape, inclined from the lower angle or coruer upwards, and of such
dimensions that, during the movement of the said points or devices, which take the
threads from the perforated steel bars, and also the pillar threads, they shall not
interfere with, or strain the said warp and pillar threads. The moving needle bar
which carries the needles, is supported above the level of the needles in a suitable
manner, preferably between the tricks and the roller or beam for the net or
material.
The triangular points or devices work below the needles and take the warp or
threads from the perforated steel bars, and also the pillar threads, and lap the
pillar thread by means of the ordinary point above the needles, said point having
an up and down and also a lateral motion, but not of the same extent as in
machines as at present constructed. The triangular point or device takes the
pillar thread forward and above the needle, said pillar thread being lapped under-
neath by the said ordinary point, and putting itself on the top of the needles in the
downward movement. The slot in the triangular point or device, through which
the pillar thread passes, draws the pillar thread with it to lift it above the needle,
but during the rest of the movement of the said triangular point the pillar thread is
unaffected. The triangular points are carried upon a bar suitably arranged at a
sufficient distance below the needle bar not to interfere with the passage of the
finished lace to the roller. Lace designs hitherto made only on Levers machines,
can be made on a warp machine constructed according to my invention, and such
as formerly made on warp machines, can be produced in greater variety.
And in order that my invention may be readily understood I will describe the
same fully with reference to the annexed drawings, in which:
Fig. 1 is a section of a warp lace machine, showing the position of my improved
points.
Fig. 2 is a side view of one form of point.
Fig. 3 is a modification of the same.
Fig. 4 represents, in elevation, the ordinary or top point bar and means for
laterally moving the same.
Fig. 5 is a perspective view showing several of the slotted points passing through
the warp and pillar threads.

page_text: Fig. 6 is a section of the working parts of a warp-lace machine showing the
slotted point bar in its highest position.
Figs. 7 and 8 are perspective views illustrating the lapping of the thread under
the needle, by the upper or ordinary point, and the formation of the loop by the-
slotted point.
•
a represents the pillar threads and 6 the warp threads, of which there may be
any number, as in the present warp machines. The warp threads b are taken up
and enclosed in the loops of the pillar threads upon the needles c, the finished lace d
being conducted underneath the needle-bar c' to the work or lace beam d'. The
needle bar is supported by arms e*, pivotted at e, and is actuated by a suitably
shaped cam f, upon the cam shaft ', acting upon the bowl or cam roll g on the
link g', or in any well known manner. The presser h, by means of its bows h¹,.
pivotted at i, and the ordinary upper point bar j, by means of its arins j', pivotted
at k, and knocking out links, pivotted at A, are actuated by suitable cams upon
the cam shaft, or in any well known manner. The point bar m, which carries the
slotted points m', is carried by curved links n, suspended at the end of arms n³,
pivotted at n², and raised and lowered by means of a cam roll n from the cam
shaft. The knocking-over levers and links p', are actuated from a cain roll p²,
by suitable cams on the cam shaft. It is obvious that various other arrange-
ments of arms, links, and cams may be employed to obtain the required motions of
the needles, points, and presser, as in warp machines as at present constructed.
The lower or slotted points m' are formed of sheet metal of a shape substantially-
as represented in Figs. 2 and 3, and are fixed in leads and secured to the point
The pillar threads (see Fig. 5) are passed through the slots r in the
points m', and the warp or thick threads & pass between the points m', but are not
passed through them. The edge of the slotted point is so shaped as not to drag
or injure the warp threads when they are shogged, and the slot is preferably
inclined so as to obtain a deeper point and lift the thread towards the needle by
the act of going through the threads. The slot is diminished at the upper end
so as to hold the pillar thread while drawing it off the beam, or bobbin, and after
the point has commenced to take
up said pillar thread.
bar m.
In Fig. 1, the point m' is shown at its lowest position below the needles. From
this position, the point moves forward and upward taking up the pillar thread with
it as soon as the upper end of the slot has reached said pillar thread, and carrying
it above the needle, as in Fig. 6, which represents the point m' in its highest
position. As well as the ordinary up and down motion, which is preferably not
quite so great as in machines as at present constructed, the upper point bar, with
points, has a lateral motion. This is obtained by operating the point bar j from
the pillar wheel, as indicated by Fig. 4. The pillar wheel operates an arm or
lever u, as in ordinary warp machines, but instead of the wire or connector v being
attached to a pillar bar, it is connected with an eye on the point bar j, and conse-
quently gives a lateral motion to the said bar. The point bar is maintained in
position by steady irons w, and guide rods w¹', and is provided with a returning
spring a. s are the perforated steel bars.
When the point m³ has lifted the pillar thread up to the level of the bottom of
the needle, the point. 3 is moved to one side by the pillar wheel, and draws with
it the pillar thread, lapping it underneath the needle, as seen in Fig. 7, so that
when the point m' has carried the thread above the needle, as in Fig. 6, and
descends from its highest position it brings the thread down on the opposite side of
the needle and leaves the threads on the top of the needle forming a loop, as in Fig. 8..
It is obvious that the triangular slotted points in no way interfere with the shogging
of the warp threads.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-

page_text: slot so shaped as to allow the point to make part of its motion without affecting
the pillar thread.
2. The special construction of point, as shown in Fig, 2 of the annexed
drawings.
3. The special construction of point, as shown in Fig. 3 of the annexed
drawings.
4. A warp lace or like machine having slotted points, as above claimed, worked
in conjunction with an ordinary point bar having a lateral motion, for the purpose
set forth.
5. In a warp lace or like machine, an ordinary point bar having a lateral as well
as an up and down motion, substantially as described and for the purpose set
forth.
6. In warp lace and like machines, the arrangement and combination of parts
whereby the pillar threads are carried up to the needles, and while in such position
moved laterally, then carried above the needles so that by the descent of the slotted
points, by which the pillar threads are held, the thread is looped over the needles,
substantially as described.
7. In a warp lace machine, carrying the pillar thread to the needles by the aid
of a point which has no lateral motion, and lapping it by means of a laterally
moving point, substantially as described.
8. My improvements in warp lace machines and the like, substantially as herein-
before described and shown.
