IMPROVEMENTS IN WARP LACE CURTAIN MACHINES
Year: 1885

page_text: I, EDWIN VANINI SMITH, of 103 Sneinton Road, Sneinton, in the County of
Nottingham, Draughtsman, do hereby declare the nature of my invention for
IMPROVEMENTS IN WARP LACE CURTAIN MACHINES," to be as follows:-
In a warp lace curtain machine of the usual construction, in which the cloth
work is made, or prevented from being made, by the use of jacks, pickers, or inter-
ceptors, selected by a jacquard or its equivalent, I employ the requisite number of
perforated steel or other fancy bars, which I place in such a position that the
threads carried by them are worked so as to lie on the surface of the clothwork or
pillaring, when necessary, or the threads carried by steel or other fancy bars may
be employed to make a variety of purlings and to produce, what is known as thick
threading, or other effects.

I EDWIN VANINI SMITH, of 103 Sneinton Road, Sneinton, in the county of
Nottingham, Draughtsman, do hereby declare the nature of my invention for
IMPROVEMENTS IN WARP LACE CURTAIN MACHINES," and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
Figure 1 shows a vertical sectional view of the several operating instruments of
a fast warp lace machine of the usual construction, with my improvements applied
thereto.
In carrying out my improvements I employ an oscillating needle bar to
which leads of latch needles A are secured, a sinker bar carrying leads of
sinker hooks B, a sinker point bar carrying leads of sinker points C, and
a bar carrying leads of pillar thread guides D. The four several bars are not
shown in the drawing, being those of the usual shape and operated in the usual
way by cams and levers. Above the sinker hooks I employ interceptors E such as
are usually employed in warp lace curtain machines, the interceptors are cast in
leads E secured to a bar E provided with an axle at each end, which rock
in bearings secured to the framing of the machine, the bar E2 is rocked by cams
and levers in the usual way, the whole of the interceptors, being placed by the bar
into the position shown in the drawing except those which are selected by the
operation of a top jacquard of the usual construction, each vertical needle of which
is attached by a cord E³ to. an interceptor. The lower selecting ends of the
interceptors slide in tricks cast in leads F secured to a bar F1 carried by brackets F
which are screwed to the underside of a bracket bar F³ which if necessary may be
caused to rock in bearings attached to the framing of the machine and operated by
cams and levers in the usual way. The lower ends of the brackets F2 each carry
a pin G upon which perforated steel bars H slide horizontally, each bar being
supplied with threads from spools. In front of the bars H a washer G¹ is placed
upon each pin G in order to keep them apart from other extra or fancy bars I, each
of which is supplied with threads from a beam. Each of the bars H and I are
traversed by a jacquard or equivalent means in the usual way. The threads
carried by the bars H and I are kept at the necessary angle by being passed
through a sley F' secured to the bracket bar F³. The selectors are prevented from
entering the threads carried by the bars I not only by the washers G¹ separating
them from the bars H, but also by a wire F* which is cast in the back of the trick
leads F. By such means the threads carried by the bars H may be jacked or
intercepted independently of the threads carried by the fancy bars I. The threads
from which working between the threads from the bars H, and the threads from
the pillar guides D (which are supplied from spools or beams) produce special
effects, such as thick threading and purling on the fabric.

page_text: 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
.
First. The use and employment in a warp lace curtain machine, of extra or
fancy bars in addition to those bars usually operated on by jacks, pickers, or
interceptors.
Second. The use and employment in a warp lace curtain machine of an end
or dropper jacquard in addition to the top jacquard or jacquards usually employed
in warp lace curtain machines.
