PROVISIONAL SPECIFICATION
Improved 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 bed of the machine is provided with an outer cam ring which holds down
the usual revolving cam ring to operate the needles in the cylinder. The revolving
cam ring carries a yarn guide bracket provided with two loops or eyes, the inner
eye has the usual yarn passed through it to make the hose or half hose, the outer
eye has the splicing thread passed through it and also through the inner eye,
both threads running in to the needles together when splicing the fabric. The splicing
thread cop is carried by the guide bracket. Between the two eyes an arm pro-
jecting from a vertical rod presses upon the splicing thread when the rod is over
the lowest portion of the outer cam ring.
When the rod is over the highest portion of the cam ring the arm is lifted
leaving the splicing thread free to run into the needles with the usual yarn.
The rod carrying the arm slides vertically in the guide bracket being held down
by a coiled spring.
By means of the above described apparatus we are enabled to automatically feed
or retain the splicing thread when required.

COMPLETE SPECIFICATION.
Improved Apparatus applicable to Circular Knitting Machines.
We GEORGE BLACKBURN, Hosiery Machinist, and AUBREY BAYLY SPRING,
Machinist, both of Atlas Work, 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 plan of our improved apparatus applied to the cam ring of a
circular knitting machine.
Figure 2 a front view of the same.
The bed 1 of each machine is provided with an outer cam ring 2 which holds
down the revolving or reciprocating ring 3, carrying the usual cams for operating
the needles in the cylinder.
The cam ring 3 carries a yarn guide bracket 4 capable of adjustment vertically
in the lower boss of a bracket 5 secured to the usual friction arc 6. The bracket 4
is provided with two loops or eyes 7 and 9, the inner eye 7 has the usual yarn 8
passed through it to make the hose or half hose, the outer eye 9 has the splicing
thread 10 passed through it and also through the inner eye 7 both threads running
in to the needles together when splicing the fabric.
The splicing thread is supplied from a cop carried by an arm 11 secured to the
friction arc 6, the splicing thread 10 is passed through a hole in a guide plate 12
secured to the arm 11, before being threaded through the eyes 7 and 9 of the yarn
guide.

page_text: Between the eyes of the yarn guide is an arm 13 projecting from a vertical
rod 14 which slides in the upper boss 5 of the bracket 5, near the lower end of
the rod a stud projects upon which a spring 15 coiled round the rod presses, and
holds the arm 13 firmly down upon the splicing thread when in the position shown
at Figure 2, while the rod is passing over the lowest portion of the cam ring 2.
The splicing thread being thereby prevented from running to the needles until the
arm 13 is raised into the position shown by dotted lines while the rod is passing over
the highest portion of the cam ring 2, the splicing thread 10 then runs in to the
needles along with the usual yarn 8.
By means of the above described apparatus the splicing thread is automatically
retained from, or fed to the needles, as the rod 14 alternately passes over the
lowest and highest portions of the cam ring 2.
The cam ring may be removed and another ring substituted having its lowest
portion of a greater or less length according to the length of splicing 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:
1. The construction and employment in circular knitting machines of a cam
ring 2 for alternately raising and lowering an arm 13 for releasing and holding a
splicing thread substantially as herein before described.
2. The construction and employment in circular knitting machines of a double
bossed bracket 5 secured to the friction are 6 of the revolving or reciprocating cam
ring 3, a yarn guide bracket 4 having eyes 7 and 9 carrying a splicing thread 10
substantially as herein before described.
3. The construction and employment in circular knitting machines of a splicing
thread cop carrying arm 11 and guide plate 12 secured to the friction arc 6, the
whole operating in combination with a circular knitting machine, substantially as
described for the purpose specified and illustrated in the drawings annexed.
