PROVISIONAL SPECIFICATION.
Improvements in Twist Lace Machine Point Bars.
I, ERNEST JARDINE of 19, Park Valley, The Park, Nottingham, Machinist,
do hereby declare the nature of this invention to be as follows:-
My invention has for its object improvements in the arrangement of the point
bars used in what are known as "low machines" that is to say in twist lace
machines having all their shafts & motions below the work roller. A point bar as
hitherto made has been cut out of a bar of iron or steel, say 14 inches square, into
an angle bar shaped like the letter L: the bar being planed into a right angle &
each side left say " thick & 11" long. The point bar arms are screwed on to the
back of the bar & the point leads are screwed on to the top of the projecting foot
of the Lor right angle bar. The point bar feet are therefore fastened to the
vertical side of the point bar and the point leads to the horizontal side.
Much time, care, & loss of material is entailed in making these bars but their
great disadvantage is on account of the lower or horizontal part of the front bar
preventing the front catch bar of the machine being lifted or moved out far enough
to enable the twisthand to readily put up threads or take the carriages out of the
machine.
My invention enables the twist hand to lift or move out the catch bars, into
their most convenient position, without coming in contact with the point bars.
I accomplish this desirable result in the following manner :-I make the point
bars out of angle iron or steel of say 14" x 11" x 1".
I plane these bars on the outsides only. The inside of the bar is not planed:
the corner being left in so as to give increased strength to the bar.
I place the bars into the machine so that the vertical side of each bar is the
nearest to the centre of the machine and the horizontal side is the top side of
the bar.
1 screw the point leads to the vertical side & the point bar feet to the top or
horizontal side.
Instead of making the point bar out of angle iron or steel I may use a square
bar and plane or cut away that part which prevents the catch bar being lifted or
moved into its most convenient position.
That part or angle of the point bars that has hitherto prevented the catch bars
being lifted into the most convenient position for the workman or twisthand is
therefore removed consequently threads can be put up more easily & quickly &
the taking out of the carriages is facilitated.

COMPLETE SPECIFICATION.
Improvements in Twist Lace Machine Point Bars.
1 ERNEST JARDINE, of 19 Park Valley in the Town and County of the Town
of Nottingham, Machinist, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention has for its object improvements in the arrangement of the point

page_text: bars used in what are known as "low machines" that is to say twist lace machines
obtaining their catch bar & point bar motions from shafts working below the work
beam or roller.
The point bars as hitherto usually made have been cut out of bars of iron or
steel, say 1 inches square, into equal sided angle bars: each bar being planed
into a right angle & each side being left say inches thick & 1 &
inches long.
The point bar feet have been fastened to the vertical side of the point bar and the
point leads to the horizontal side.
Much time, care & loss of material is entailed in making these bars but their
great disadvantage is on account of the lower or horizontal part of the front bar,
preventing the front catch bar of the machine being lifted or moved out far enough
to enable the twisthand to readily put up threads or take the carriages out of the
machine.
My invention enables the twisthand to lift or move out the catch bars, into their
most convenient position, without coming into contact with the point bars.
I accomplish this desirable result in the following manner :-
I make the point bars out of angle iron or steel of say 14 inches x 1 inches x
inch.
I usually plane these bars on the outside only. The insides of the bar need
not be planed the corner being left in so as to give increased strength to
the bar.
I place the bars into the machine so that the vertical side of each bar is the
nearest to the centre of the machine and the horizontal side is the top side of
the bar.
Iscrew the point leads to the vertical side & the point bar feet to the top or
horizontal side.
Instead of making the point bar out of angle iron or steel I may use a square
bar and plane or cut away that part which prevents the catch bar being lifted or
moved into its most convenient position.
That part or angle of the point bars that has hitherto prevented the catch bar
being lifted into the most convenient position, for the workman or twisthand, is
therefore removed: consequently threads can be put up more easily & quickly &
the taking out of the carriages is facilitated.
In order that my invention may be more clearly understood & readily carried
into effect, I will proceed, aided by the accompanying drawings, more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is part sectional elevation of a "low" twist machine of the usual con-
struction showing an ordinary point bar A. with catch bar D. in the most con-
venient position for getting the carriage E. out of the machine, B. is a point lead,
C. a point bar foot, D. shows the catch bar raised from the position it occupies
when at work, & shewn by the dotted lines at F. E is a carriage. The object of
Fig. 1 is to show that the catch bar D. cannot be raised into a more convenient
position because it comes into contact with the point bar A.
Fig. 2 is part sectional elevation of a "low" twist lace machine showing my
improved point bar G. & point bar foot H. with the catch bar D. in the most
convenient position for getting the carriage E. out of the machine.
1. is a
point lead & F. shows in dotted lines, the position of the catch bar D. when
at work.
Fig. 3 is a plan showing part of one of my improved point bars G. with point
bar foot H. and point leads 1.
The drawings show the construction and arrangement of the front point bar only
as the back point bar is usually made exactly like it.

page_text: Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed 1 declare that what 1
claim is
In "low" twist lace machines the arrangement combination & construction of
point bars & point bar feet substantially as herein shown & described & for the
purpose stated.
