IMPROVED WARP MACHINES FOR PRODUCING PATTERNED AND FASHIONED FABRICS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, WILLIAM START, of Arboretum Works, North Sherwood Street, in the town
and county of the town of Nottingham, Machinist, do hereby declare the nature of
the said invention for "IMPROVED WARP MACHINES FOR PRODUCING PATTERNED
AND FASHIONED FABRICS," to be as follows:-
:-
Each machine consists of the following parts, standards and connecting rails,
carrying bearings for a driving shaft, and a cam shaft, at the front of the machine
is a rocking axle shaft carrying arms connected by links to a pair of driving bars;
these bars slide vertically being operated by cams, to raise and lower needles in
needle jacks which slide in a sley, secured at the back of the driving bars is a bar
carrying springs one to each needle jack, these springs may be acted upon by
strings from a jacquard, or the needle jacks may be acted upon direct from the
jacquard cards. In front of the needle sley is a hook bar carrying leads of hooks,
actuated in the usual way by cams, above the needle aley are machine brackets, in
which ordinary guide bars slide, the brackets being carried by a rocking shaft, the
traverse of each guide bar is effected by the interposition of droppers between an
adjustable bolt at one end of the bar, and the upper end of a rocking lever carrying
a truck at its lower end actuated by a pattern wheel on a short shaft at right
angles to the cam shaft, both shafts being connected by toothed bovel gearing. By
such means I am enabled to produce either patterned fabrics, or fashioned, or
shaped fabrics, by simply placing those needles required, in position to receive their
yarn.

and county of the town of Nottingham, Machinist do hereby declare the nature of
my invention for IMPROVED WARP MACHINES FOR PRODUCING PATTERNED AND
FASHIONED FABRICS 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 front view of one of my improved warp machines.
Figure 2 shows a sectional view, both views are drawn one quarter the full size.
Figure 3 shows, a full sized sectional view of the needle aley, hook bar, driving
bars, spring bar, and guide bars in their several relative positions.
Figures 4 show a side view and edge views of two droppers referred to hereafter.
Figures 5, 6 and 7 show side views of a pattern wheel and cams severally referred
to hereafter.
ર
Each machine consists of the following parts, see Figures 1, 2 and 3, two end
standards A, and three connecting rails B, one at the front, and two at the back, to
the standards are secured bearings for a driving shaft C, provided with pulleys and
a fly wheel at one end, and a toothed wheel C' at the opposite end, gearing into a
larger toothed wheel on a cam shaft D, on the right end of the cam shaft is secured
a toothed bevel wheel hereafter referred to. At the front of the machine is a
rocking axle shaft E, carrying arms connected by links E¹ to a pair of driving
bars E and E³, these bars slide vertically, being operated by two cams F, one of
which is shown in side view at Figure 5, the driving bar E raises, and the driving
bar E lowers needles, each of which is secured in a needle jack G, these jacks slide
in a sley G', which is secured to brackets projecting from the end standards, the
driving bar E has two arms secured to it, the lower ends of which are attached
to a bar to the frout of which, leads carrying springs H are screwed, the upper
end of each spring is thrice cranked (as shown in Figure 3), and is perforated at
the back so as to connect it to a string from a jacquard of the usual construction
placed above the machine, (these strings are only shown at Figure 2), the lower
eranked portion of each spring lies under a stud in the needle jack, when not drawn
clear of it, by the action of the jacquard (the needle jacks form a sley for the upper
ends of the springs H) pushes the jack up into the position shown at Figure 3, but
when the spring is moved back clear of the stud by the action of the jacquard, the
jack remains down resting upon the bar E², being so placed by the lowering of the
falling bar E3 at each course, the falling bar is hinged near each end to the upper
end of arms E having their lower ends attached to the spring bar, the hinging of
the bar to the arms is to enable the attendant to turn the falling bar backward, to
withdraw or insert a needle jack at need, in front of the needle sley is a bar to
which leads of hooks I are screwed, actuated in the usual way by two cams I', one
of which is shown in side view at Figure 5, above the needle sley are machine
brackets in which ordinary guide bars J slide, the brackets being carried by a
shaft J rocking in bearings formed in the end standards, the rocking of the shaft
is effected by a link, shown by dotted lines at Figure 2, the lower end of which is
hinged to an arm carrying a truck operated by a cam J³, at the left end of the
machine; a side view of this cam is shown at Figure 6, the traverse of each guide
bar is effected by the interposition of droppers (shown separately at Figures 4)

page_text: between an adjustable bolt Js, at the right end of the bar, and the upper end of a
rocking lever J' carrying a truck at its lower end, actuated by a pattern wheel J'
shown in side view at Figure 7, the pattern wheel is carried by a short shaft K at
a right angle to the cam shaft; the shaft K revolves in bearings on brackets, secured
to the right end standard and is provided with a toothed bevel wheel near its front
end gearing into a smaller bevel wheel, secured on the right end of the cam shaft,
before referred to. The droppers are attached to strings operated by the jacquard
before named. The jacquard is actuated by a jacklifting cam L shown in side view
at Figure 7 and the jacquard cylinder by a link having its lower end connected to
an eccentric pin L' carried by the cam J.
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 construction and employment of a warp machine, in which the needle jacks
and needles are selected by a jacquard to produce patterned and fashioned or shaped
fabrics, substantially as described and illustrated in the Drawings annexed.
