PROVISIONAL SPECIFICATION.
Improved Apparatus applicable to Straight Bar Knitting Machines
for Producing Striped Hosiery Fabrics.
We THOMAS HILL of the Firm of I. and R. Morley, Fletcher Gate, Nottingham,
Hosiery Manufacturers, GERVAS MATTHEWS, Factory Manager, and ELIJAH
GODDARD, Overlooker, both in the employment of the said firm, do hereby declare
the nature of this invention to be as follows:--
To produce clear edged colours in all kinds of vertical striped hosiery fabrics
without showing pearling, or reverse coloured stitches or loops on the face of the
fabric, the usual sinkers are employed across each division of the machine, but
where the stripes join, one sinker is shorter than the others and shaped to ride over
the thread at the lower angle to avoid knitting. And each thread carrier is made
to shog one or more needles at each traverse to form the join.
The carrier rods being stopped at each end by a lever connected by a link to a
truck bearing lever operated by a cam on the cam shaft.
Dated this Twentieth day of October 1894.

page_text: The usual jack sinkers 1 and dividing sinkers 2 are employed across each division
of the machine, as shown at Figure 4 but where the stripes join one sinker 3 is
shorter than the others its lower net being cut away to the shape shown to ride
over the threads 4 at the lower angle at the commencement of the draw from the
left to the right, as shown at Figure 4. The back end of the lever 6 is made
thinner and while in the position shown at Figure 3 each thread carrier is made
to shog one needle at the end of each traverse to the left to form the join.
The carrier rod 5 being stopped at the left end by the lever 6 sliding in a fork 7
"secured to the carrier rod bearing bar 8" against a stop 9 on the end of the
bearing bar.
The outer end of the lever 6 is hinged to a lever 10 bearing a truck 11 at its
lower end and rocking on an axle 12. secured to the end standard of the machine,
the truck being held to a cam 13 on the end of the cam shaft, by a spring 14
having one end hooked to the lever 10 and its other end to the standard.
The end of the carrier rod 5 is provided with two collars between the collars is a
loose bearing 15 which supports the carrier rod end and slides to and fro with it
on the bearing bar 8.
In the drawings the improved apparatus is shown as applied to the left end only
of a straight bar knitting machine but it would be equally as effective if applied to
the right end only. In which case the shortened sinker 3 would ride over the
thread 4 at the lower angle at the commencement of the draw from the right to the
left after the thread carrier had shogged one needle at the end of each traverse to
the right to form the join. And by making the back end of the lever 6 still thinner
a traverse to the left or right may be made over two needles to form the join at the
back leaving a clear join on the face.
The improved apparatus operates as follows. The catch bar having drawn the
jack sinkers 1 dividing sinkers 2 and the shortened sinkers 3 back the thread
carriers are traversed one needle to the left while the needle heads are just clear
of the sinker nebs to pass the thread 4 round the first needle of the next stripe to
form the join at the back leaving a clear join on the face of the fabric.
By which means the left edge of any stripe joined to the right edge of the next
stripe will have a clear join distinct in colours on the face of the fabric as shown
at Figure 5, the thread of one stripe being passed round the first needle of the next
stripe at the back of the fabric as shown at Figure 6.
When fashioned fabrics are being made only the intermediate thread carriers are
operated as before described to traverse the threads over one or more needles,
the selvage carriers being operated by one or more other carrier rods to widen.or
narrow the fabric in the usual way.
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 :-
In straight bar knitting machines the construction and employment of shortened
and undercut sinkers 3, a thread carrier rod stopping lever 6, a truck bearing
lever 10 and cam 13 operating in combination, substantially as described for the
purpose specified and illustrated in the drawings annexed.
