Complete Specification Left, 19th Apr., 1893-Accepted, 20th May. 1893
PROVISIONAL SPECIFICATION.
Automatic Apparatus applicable to Circular Knitting Machines.
We GEORGE BLACKBURN, Hosiery Machinist, and AUBREY BAYLY SPRING;
Machinist, both of Atlas Works, Kirke White Street, Nottingham, do hereby
declare the nature of this invention to be as follows:-
The apparatus consists of a rocking lever operated by the links of a pattern
chain, the lever rocks on an axle secured to the framing of a circular knitting
machine known as the Scott and Williams machine.
One end of the lever is connected by a universal joint to one end of a rod
capable of adjustment as to its length, the other end of the rod is connected by a
universal joint to a lever provided with two cam runs working on the stalk of the
clamp which raises and lowers the needle cylinder.
By means of the apparatus above described we are enabled to gradually stiffen
the fabric made on the machine to form the shape required.

COMPLETE SPECIFICATION.
Automatic Apparatus applicable to Circular Knitting Machines.
We GEORGE BLACKBURN, Hosiery Machinist, and AUBREY BAYLY SPRING,
Machinist, both of Atlas Works, Kirke White Street, Nottingham, do hereby
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 left side view of the apparatus.
Figure 2 a plan of the same, and
Figure 3 a front view of a cam on the stalk of a clamp hereafter referred to.
The apparatus consists of a lever 1 rocking on an axle 2 secured to the framing 3
of a circular knitting machine known as the Scott and Williams machine.
The lower end of the lever 1 is connected by a universal joint 4 to one end of a
rod 5 capable of adjustment as to its length by means of a set screw the other end
of the rod is connected by a universal joint 6 to a lever 7 provided with two cam
runs 8 working on the stalk of the usual clamp 9 which raises and lowers the needle
cylinder. From the clamp stalk two pins 10 project and rest upon the cam runs.
The upper end of the lever 1 is held to a pattern chain by a coiled spring 11
having one end hooked on a stud projecting from the lower end of the lever, the
other end being hooked on a rod 12 secured in the framing of the machine.
The pattern chain for operating the rocking lever 1, not shown in the drawings
as the number of links and their shape vary according to the pattern required is
carried by a sprocket drum 14 provided with a double ratchet wheel 13 revolving
on the outer end of a lengthened axle substituted for the axle carrying the ratchet
wheel 46 and sprocket drum operating the chains 25 shown at Figures 2 and 3 and
described at lines 33 to 37 on page 6 of Scott and Williams, English Patent
Specification No. 1417 January 26th 1891.
The chains carried by the sprocket drum 14 also pass round a drum 15 revolving
n an axle projecting from a boss 16 capable of adjustment on a rod 17 held by a
. 027

page_text: bracket secured to the framing of the machine, the intermittent movements of the
chains being made in the same way as the chains 25 described in the Specification
before referred to.
The pattern chain for operating the rocking lever 1 is formed of the requisite
number of links varying in height, when the lever presses upon the lowest link the
coiled spring 11 forces the lever 7 into the position shown in the Figures 1, 2
and 3 placing the clamp 9 and the needle cylinder in the lowest position.
Then as the links gradually increase in height the lever 7 will be traversed in
the direction of the arrow shown at Figure 2, until the highest link pressing, upon
the lever I will force the lever 7 to the left placing the clamp 9 and the needle
cylinder in their highest position.
: :
As the links of the pattern chain decrease in height the needle cylinder is
lowered, the needles drawing a shorter loop make the fabric narrower. And as the
links increase in height the needle cylinder is raised the needles drawing a longer
loop make the fabric wider thereby forming the shape required.
By employing the above described apparatus in combination with. circular
kuitting machines known as the Scott and Williams machine, we are enabled to
quickly take out one needle cylinder and replace it by another when required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
The construction and employment of automatic apparatus applied to and
operating with circular knitting machines known as the Scott and Williams
machine substantially as described and illustrated in the drawings annexed.
