IMPROVEMENTS IN THE CONSTRUCTION OF WARP LACE MACHINES
Year: 1884

page_text: I, HENRY HILL, of the Firm of Balm, Hill, and Sons, of Mansfield Road, in the
town and county of the town of Nottingham, Lace Manufacturers, do hereby
declare the nature of the said Invention for IMPROVEMENTS IN THE CONSTRUCTION
OF WARP LACE MACHINES," to be as follows:-
My improvements consist in the application to a warp lace machine of a stump
bar or bars, the threads in the holes of which are dragged or held to one or other
of the sides thereof by other bars placed at a convenient distance from the stump
bar or bars. This stump bar or bars, is, or aro, placed relatively in such a position
with regard to the needles and sinkers, pickers, or points, that the threads
therefrom may be taken by the said sinkers, pickers, or points, and when placod
round the needles, so as to assist in forming the looped portion of a warp machine
fabric, or worked on to the looped net, pillaring or fabric, in the same way that the
threads, in the ordinary fancy bars are used.
By this addition to a warp lace machine, I am enabled to obtain with the stump
bar or bars, and their accompanying drag bars or holding bars, effects which would
otherwise require a larger number of ordinary fancy bars than can be conveniently
worked.

page_text: DESCRIPTION OF THE DRAWINGS."
Figure 1 shows a sectional view of one of my improved warp laco machines,
carrying latch needles, and showing the position of the stump bars I employ, but
having the lower part of the standards broken away.
Figure 2, shows a sectional view of the operating instruments, drawn the full
size.
Figures 3, 4 and 5, show separate views of the stump bars, severally referred to
hereafter.
Figure 6 shows the position of the stump bar when employed in a warp lace
machine carrying bearded needles.
The corresponding parts in cach Figure are lettered alike where necessary.
My improvements consist firstly, in the application to warp lace machines
carrying latch needles, of a stump bar or bars A see Figures 1 and 2, each carried
by a bar B, held by brackets secured to either the end and intermediate standards,
or to the main tio bar, or other convenient portion of the framing of the machine.
The stump bars have a right and left traverse communicated to them when
required by means of notched wheels or by a jacquard at one end of the machine,
above the stump bars are their accompanying fining bars C, (through which the
threads C pass), these fining bars, have the requisite traverse communicated to them
by what is called in the levers lace trade, a bottom bar jacquard, such traverse is of
sufficient length to drag each thread to either end of the hole in the stump bar,
through which it is passed, causing the threads to travel the determined distance,
so that the required picker point or sinker D, shall tako and lap it into the work,
so as to form the desired pattern. At Figures 1 and 2, the picker points or sinkers
are shown in the position they occupy, after having passed through the stump bar
threads C, the fancy bar threads G, and the looping bar threads E, and has moved
downwards, which movement lays the threads onto the needles, the points or
sinkers are then moved backwards, and rise again to repeat their movements the
next course.
Figure 3 shows a front view of portion of one stump bar, and its carrying bar.
Figure 4 shows a sectional view of the same, and
Figure 5 shows a plan of portion of one stump bar.
In these Figures A is the stump bar, B the bar which carries it, the bar A being
shown at Figure 3 in longitudinal section, C¹ is a thread dragged to the left end of
one of the holes in the stump bar, by one of the fining bars C, C is a thread
dragged to the right end of one of the holes in the stump bar, by another of the
fining bars C.. D shows the point of a picker or sinker, entering the threads close
under the stump bars to take the threads as determined. F is the top of the truck
or knocking over bar through which the needles work.
Figure 6 shows a sectional view of the stump bars in position, when applied to
a warp lace machine carrying bearded needles, A are the stump bars, C the fining
bars, and G gimp bars, D the pickers or sinkers, H the needles, I the lapping
thread points, and K the pillar guide bar or lapping bar.

page_text: The several separate and combined movements of the operating instruments
shown at Figures 1 and 2, are effected by links, levers, and eccentric cams, fully
described in the Specification of a former patent No 5235, March 21st 1884, for
'Improvements in the construction of warp lace machines."
"
The operating instruments shown at Figure 6, are moved by links, levers and
suitable shaped cams, in the usual way.
Thus by the application of a stump bar or bars, and corresponding fining bars,
in a warp lace machine, either carrying latch needles or bearded needles, I am
enabled to produce that portion of a warp lace pattern which may be called the
weft threads, or by placing the stump bar or bars, in a suitable position, they may
be made to produce the pillaring or looped portion of a warp lace fabric.
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 application to a warp lace machine carrying either latch needles or bearded
needles, of a stump bar or bars with corresponding fining bars arranged so as to
produce either the weft portion, or the pillar or looped portion of warp lace fabrics,
substantially as described and illustrated in the Drawings annexed.
