page_text: I HENRY SCATTERGOOD of Whitehall's Factory Wollaton Street, Nottingham,
Nottinghamshire, Machinist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WARP LACE MACHINES to be as follows that is to say:―
"
This Invention relates to warp lace machines of the kind in which the needles
are placed horizontally and it has for its object the construction of the machine or
arrangement of parts of such machines in an improved and convenient manner
whereby the rate of working is quickened.
In the improved machine the horizontally placed needles have a to and fro
horizontal movement and the hook bar is placed above the needles and has given
to it a simple vertical motion whilst the point bar underneath the needles has an
alternately rising and falling motion combined with a to and fro movement. By
this Invention also one or more pillar bars may be used and the pillar bar (or bars)
is fixed on the inner end of short arms extending horizontally from a rocking shaft
running longitudinally along the machine. This rocking shaft has communicated.to
it motion which gives the pillar bar a simple up and down or approximately a
vertical movement. By the aforementioned improved combination and arrange-
ment of parts the machine is rendered more compact and convenient and works
with less noise and vibration and with greater speed than warp machines as
hitherto constructed. Also it is rendered possible by the improvements to employ
with greater convenience a larger number of steel bars than heretofore.

page_text: I, HENRY SCATTERGOOD of Whitehall's Factory, Wollaton Street, Nottingham
Nottinghamshire, Machinist, do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN WARP LACE MACHINES," and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement that is to say:-
My said Invention relates to warp lace machines of the kind in which the
needles are placed horizontally, and it has for its object the construction of the
machine or arrangement of parts of such machines in an improved and convenient
manner whereby the rate of working is quickened.
In-the-improved-machine the horizontally placed needles have a to and fro
horizontal movement, and the hook bar is placed above the needles-and-has-given
to it a vertical motion whilst the point-bar underneath the needles has an
alternately rising and falling motion combined with a to and fro movement.
One or more pillar or guide bars may be used and the guide bar is (or bars are)
fixed on the inner end of short arms extending horizontally from a rocking
shaft running longitudinally along the machine. This rocking shaft has com-
municated to it motion which gives the guide bar a simple up and down or
approximately a vertical movement. By the aforementioned improved combination
and arrangement of parts it is rendered possible to employ with greater con-
venience a larger number of steel or other bars for fancy threads than heretofore.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing by way of a diagram my improved
arrangement of the principal working parts of a warp lace machine. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
The improved warp lace machine is preferably constructed with the various
working parts placed at and above the middle of the machine and the beams for
carrying the threads are carried on the framing but below the working parts so
that the fabric as it is produced proceeds upwards being wound on a roller carried
by the framing near the top of the machine. On referring to the diagram Figure 1
it will be seen that the needles 2 cast in leads 3 as usual are secured to a bar 4
extending the length of the machine so as to lie horizontally. This bar 4 has a
backward and forward movement imparted to it by means of links from a cam
shaft which is carried in suitable bearings at the back of the machine at a suitable
height receiving motion from a first motion shaft or otherwise. The sinker hooks 5
cast in loads 6 are fixed on a bar 7 which extends along the machine over the
needles. An up or down or vertical movement as well as a slight to and fro
motion is given to this bar 7 and sinker hooks 5 by an ordinary arrangement of
levers and links connecting it with the cam shaft. Underneath the needles 2 and
bar 4, points 8 cast in leads 9 are secured upon the point bar 10 to which bar 10 a
to and fro and an up and down movement is imparted by means of links and
levers from the cam shaft. The fancy threads 11 which require to be worked into
the fabric 12 are passed through suitable holes in the steel guide bars 13 of which

page_text: there are any required number carried by brackets 14 fixed to the framing of the
machine. These steel bars 13 are operated by the usual jacquard apparatus and
are placed so as to leave space between the needles 2 and the steel bars 13 for the
points 8 to rise and fall for the purpose of "selecting" as hereinafter described. In
front of the needles 2 there are arranged a number of guides 15 having the usual
holes in their ends to receive threads. These guides 15 are cast in leads 16 which
are secured upon a pillar or guide bar 17. This pillar bar 17 is carried on the outer
ends of arms 18 which are fastened on a rocking shaft 19 carried in bearings
on the framing. Motion is communicated to this rocking shaft by levers and
links from the cam shaft so that the points of the guides 15 have an approximately
up and down movement that is so as to bring them alternately slightly above and
just below the needles 2 between which the guides enter a short distance when
the needles are at the extreme forward end of their traverse. The guide bar 17
has also a lateral movement given to it by means of a jacquard notched wheel or
other known arrangement so that the points of the guides 15 have a motion which
causes them to lap the threads passing through them on the hooks of the needles 2
thus forming the looped portion of the fabric 12 when the course is finished. The
motion of the machine is as follows reference being had to the diagram Figure 1 on
the accompanying drawings. When the parts are in the position indicated by the
full lines on the drawings the sinker hooks 5 are just in the position to enter in
between the group of threads 11 on the points 8 and by their next rising movement
bring them up to the needles 2 the points 8 mean while descending to the position
shown in dotted lines. The sinker holes 5 when in their highest position as shown
in dotted lines in the diagram, will have brought the selected threads up round
the needle heads and have placed them at the back of the needle so that the next
movement of the looping threads in the guides 15 will fasten the selected threads
in the work. The jacquard apparatus having re-arranged the threads by operating
the steel bars 13 the points 8 are again brought forward and moved upwards thus
making a fresh selection of threads which are again taken off the points 8 by the
sinker hooks 5 which by this time will be again in the first position when the
action just described will be repeated. It is obvious that all or any of the afor-
mentioned motions of the machine may be obtained by an arrangement of eccentrics
instead of cams.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
The combination and arrangement of a hook bar (7) and point bar (10) with a
needle bar (4) pillar bar (17) and fancy thread steel bars (13) operating sub-
stantially as and for the purposes hereinbefore described with reference to the
accompanying diagram.
