page_text: 1, AARON BAKER, 292 Nottingham Road, Ilkeston, Derbyshire, Warper, do hereby
declare the nature of this invention to he as follows
-
Heretofore spring jacks employed in twist lace machines, warp machines and other
machines in which spring jacks are used have been formed with straight stems from
the bend, loop, or eye, (to which the strings of a jacquard have been attached,) to the
lead cast on the ends of the stems, instead of this I bend the stem of each jack back
upon itself a short distance above the lead cast on them or above the bar in which the
stems are soldered, and form the stem into a D, C oval or circular shape then bend it
back into a line or nearly so with the lower end of the stem and continue the stem in
a straight line to the bend, loop, or eye below the head or selecting end of the jack,
the head may be formed single or double and of any form usually employed or of any
shape which may be required, the portion of the stem bent to a D, C, oval or circular
shape cause to be flattened either in a line with the length of the lead cast on
it or at a right angle thereto, such bent portion forms a spring. Jacks so con-
structed may be cast in leads secured to a bar or may be soldered in tricks cut in a bar
rocked in the usual way to insert the heads or selecting ends in the threads, or each
jack may be pulled in or kept out of the threads by the string of a jacquard in the
usual way.
In either case jacks constructed as above described may be worked with greater ease
and with less stress upon the strings of the jacquard employed, than when employing
straight stemmed jacks.

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 :—,
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view of one of my improved jacks with a lead cast on the
lower end.
Figure 2 a back view of one jack without the lead.
Heretofore spring jacks employed in twist lace machines, warp machines and other
machines in which spring jacks are used have been formed with straight stems from
the bend, loop, or eye A" to which the strings of a jacquard are attached" to the
lead B cast on the lower ends of the stems. Instead of such straight stems, I bend
the stem of each jack back upon itself a short distance above the lead or above the bar
in which the lower ends of the stems are soldered, and form the stem into a D, C, oval,
or circular slape C, flattened, then bend it back into a line or nearly so with the
lower part of the stem and continue the stem in a straight line to the bend, loop, or
eye A below, the head or selecting end of the jack, the head may be formed single as
shown, or double and of any form usually employed, or of any shape which may be
required.
The bent portion C1 cause to be flattened either in a line with the length of the
lead B or the bar in which the lower ends of the jacks may be soldered, such bent
portion forms a spring.
The bar carrying such improved jacks is rocked in the usual way to insert the heads
or selecting ends of the jacks in the threads, or each jack may be pulled in or kept out
of the threads by the string of a jacquard in the usual way.
In either case jacks constructed as above described may be worked with greater
ease and with less stress upon the strings of the jacquard employed, than straight
stemmed jacks.
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
The improved spring jacks substantially as described and illustrated in the Drawings
annexed.
