PROVISIONAL
SPECIFICATION.
Improvements in Twist Lace Machines.
I, HERBERT REDGATE of 1344 Queens Walk in the Town and County of the
Town of Nottingham Lace Manufacturer do hereby declare the nature of my
said invention to be as follows:-
The object of my invention is to effect improvements in the construction of
apparatus, in connection with the working of catchbars in twist lace machines.
In carrying out my invention, I fit plates to the machines, herein after called
:$ counters; which counters are attached to the cradles, at each side of the
machine, where the ends of the catchbars ride, to give them the necessary motions
to move the triangular bobbin carriage to and fro.
The counters are attached by an axle to the cradles, and over the open space of
the cradles, a curved slot is formed in the counters where the trucks at the ends of
the catchbars, move in the direction required, to work the bobbin carriage back-
wards and forwards. These counters ensure the catchbars falling into the ears of
the carriages at the proper time and prevent them escaping therefrom when the
machine runs at a greater speed. The axle is required so that the counters may be
thrown back to allow the catchbar to be in a convenient position to put in the
threads, when the machine is stopped for that purpose.

COMPLETE SPECIFICATION.
Improvements in Twist Lace Machines.
I, HERBERT REDGATE, of 134ª Queens Walk, in the Town and County of the
Town of Nottingham, Lace Manufacturer, do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to effect improvements in the construction of
apparatus in connection with the working of catch-bars in twist lace machines.
In carrying out my invention, I fit metallic plates at each end of the machine,
which plates are herein after called counters." These counters are formed in
two parts, and arranged at each end of the machine.
The back parts of the counters are fastened by means of screws, or equivalent
devices, to the back comb bar; and the front parts of the counters are dovetailed
to the back parts, in such a manner that the front parts may be readily detached
from the back parts of the counters by sliding the same laterally, when required, in
order to replace broken threads in their places, by which means I am enabled to
dispense with the axle mentioned in my Provisional Specification.
Curved slots are formed in the counters in which the trucks or pulleys at the
cuds of the catchbars move in the direction required, to work the triangular bobbin
carriages backwards and forwards. These slotted counters ensure the catchbars
falling into the ears of the carriages at the proper time, aud prevent them escaping
therefrom, when the machine runs at an increased speed.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing.
is one of the back counters; both of the back counters being firinly fixed to
the back comb-bar at k, by means of screws l.

page_text: The front counters a, (one of which is shown on the drawing) are dovetailed
to the back counters, as shown at c, and by dotted lines. dande are curved slots
formed in the counters, wherein trucks or pulleys travel from one extremity to the
other, one of the trucks m being shown. These trucks or pulleys are attached to
the ends of the catch bars, as shown at g. shows one of the carriages in outline.
The front counters a are supported at upon the front comb bar, and are capable
of sliding thereon when threads have to be replaced, or for other purposes.
is an opening formed in the counters, between the comb bars, for the passage of
the guide bar rods in connection with the wheels, for imparting the movements to
the threads forming the lace fabric.
By means of my invention, I am enabled to increase the speed of working from
120 revolutions per minute or thereabouts to 250 revolutions and upwards; the
trucks being securely held in position in the curved slots, and thereby compelling
the catch bars to fall into the ears of the carriages at the proper moment, and
preventing accidents at high speeds.
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
1. In a twist lace machine, the combination of metallic plates, herein called
"counters," at each end of the machine, such counters being supported by the
comb-bars and also united by dovetail joints, or equivalent mechanical devices; one
pair of counters being fixed and the other pair capable of sliding laterally; the
same counters being also formed with curved slots for carrying the trucks or rollers
attached to the catch-bars, and thereby controlling the motions of the catch-bars
and carriages; all severally operating substantially as and for the purposes herein
before described, and illustrated by the drawing.
2. In a twist lace machine, the method of directing and controlling the movements
of the catch-bars and triangular top carriages, in their motions to and fro, where
the fabric is formed on their tops without the aid of point bars, by means of counters
having curved slots formed therein, substantially as and for the purposes hercin
before described and illustrated by the drawing.
3. The general construction, arrangement, and combination of the several and
respective parts, together forming my invention of improvements in twist lace
machines, substantially as herein before described and illustrated by the drawing.
