IMPROVE- MENTS IN FAST WARP LACE MACHINES
Year: 1884

page_text: I, WILLIAM SMEDLEY, of the firm of Smedley and Sons of the town and county
of the town of Nottingham, and Sandiacre in the county of Derby, Laco
Manufacturers, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN FAST WARP LACE MACHINES," to be as follows:-
To a fast warp lace machine of the usual construction, in which a movable needle
bar is employed, I apply two or more guide bars, either or all of which I arrange
to lap their threads on the bearded or latch needles, employed in the machine.
Each of the guide bars have separate movements, communicated to them either by
cam wheels, or by a spring dropper jacquard, (heretofore the pillar bar only has
been employed to lap its thread on the needles).
The whole of the said bars I employ to produce either "lap and press" lace
fabrics, or "lap and knock off, lap and press" (commonly called "knock off"
fabrics) which "knock off" motion has not been applied to the fast warp lace
machine heretofore, and I am enabled to produce twice the quantity of fabric in
a given time, than heretofore.
CONTULIE
DELCIFICATION
I, WILLIAM SMEDLEY, of the Firm of Smedley and Sons, of the town and
county of the town of Nottingham, and Sandiacre in the county of Derby, Lace
Manufacturers, do hereby declare the nature of my invention for "IMPROVEMENTS
IN FAST WARP LACE MACHINES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-

page_text: Figure 2 is a front view of the guide bars, and one of the bearing brackets
carrying the axle of the cam wheels hereafter referred to, and
Figure 3, a plan of the same. Figures 2 and 3 are drawn one half the full size.
In the sectional view Figure 1, A is a side view of one needle lead and needle,
which is secured in the usual way to a movable needle bar, above which are the
brackets, carrying the required number of steel bars B, between the needles are
sinker hooks C, which bring the threads traversed by the steel bars down in front
of the needles, D are the sinker points which pass up through the guide bar
threads, and take back the work, E is the usual pillar guide bar, which heretoforo
only has been employed to lap its threads on the needles, such bar has been held
up to a stop by a spring E' at one end, and traversed by a cam wheel at the
opposite end, the steel bars B being traversed by a spring dropper jacquard or
other jacquard at the same end. In addition to which I apply two or more guide
bars Feither or all of which I arrange to lap their threads on the bearded or latch
needles employed in the machine. Each of the guide bars F have separate
movements communicated to them by cam wheels G (shown respectively in side
view and plan at Figures 2 and 3) which operate rocking shaped levers carrying
slotted adjustable bits, each connected by a link to one end of one of the guide
bars F, the opposite end of each bar being held by a spring in the usual way.
The axle G of the cam wheels, and the axle C² of the rocking levers are carried
by bearing brackets attached to the framing of the machine, at the opposite end to
the spring dropper jacquard. The axle G¹ of the cam wheels carries a toothed
wheel G³ which is caused to revolve by a three winged cam plate G', of ordinary
construction secured on the back cam shaft of the machine. The toothed wheel C³,
and winged cam plate G are only shown in side view at Figure 2.
The whole of the said bars I employ to produce either "lap and press
lace
fabrics, or "lap and knock off lap and press "(commonly called. "knock off."
fabrics) which "knock off" motion has not been applied to the fast warp laco
machine heretofore, and I am thus enabled to produce twice the quantity of fabric
in a given time than heretofore.
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 employment of the additional guide bars F in conjunction with the
ordinary pillar guide bar, and steel bars, substantially as described, and illustrated
in the Drawings annexed.
