Improvements in or relating to Circular Knitting Machines.
We, EDWARD WILLIAM LEE of the firm of Lee and Glenn of Wigston in the
County of Leicester, Hosiery Manufacturer, and GEORGE EDWIN BURNHAM of
Wigston, Mechanic, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to Griswold and similarly constructed knitting
machines, capable of producing ribbed fabrics, and has for its object the provision
of means for shogging the dial or portion of the machine carrying the rib needles,
in order to facilitate the formation of the welt of the fabric, and for other
purposes.
To carry out our invention we employ a suitably shaped upright arm or post in the
interior of the cylinder, working freely on a pivot or equivalent at its lower end and
capable of receiving a side-ways motion, from a suitable handle or lever, extending
outwards from underneath the frame.
The upper end of the upright post actuates a lug or projection on the under side
of the dial carrying the rib needles and after a course of the fabric has been knitted
and the rib needles withdrawn from between the frame needles, the ribbing dial is
caused to move on its axis just sufficiently to allow the needles to intercalate between
the next adjoining frame needles.
One or more courses in the fabric may now be knitted after which the ribbing
dial may be returned to its original position and the work proceed in the usual
way.

Improvements in or relating to Circular Knitting Machines.
We, EDWARD WILLIAM LEE (of the firm of Lee & Glenn), of Wigston Magna in
the County of Leicester, Hosiery Manufacturer and GEORGE EDWIN BURNHAM,
Mechanic in the employ of the above, 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:-
f
The present invention relates to Griswold and similarly constructed knitting
machines, capable of producing ribbed fabrics, and has for its object the provision of
means for shogging the dial or portion of the machine carrying the ribbing
needles, in order to facilitate the formation of the welt of the fabric and for other
purposes.
In the accompanying drawings, Figure 1 is a sectional elevation of a circular
knitting machine embodying our improvements.
Figure 2 is a plan of the same with the ribbing dial removed.
Figure 8 is a view shewing the lug under the dial plate.
A is a lug formed on the underside of the ribbing dial A and B is an upright rod 1
or post, in the interior of the cylinder, and the lower end of which is secured to
a movable horizontal bar C by means of screws C¹ or equivalent means.
This movable bar is carried in the feet or arms D, containing the clamping screws
by which the machine is fixed to a table or other support to be in position for working,
and is capable of receiving a longitudinal motion imparted by hand through the
medium of the handle E, the extent of such motion being regulated by means of the
screw bolt F and block F1, the spiral spring G or an equivalent thereof being employed
to cause the horizontal bar C to return to its original position after it has been so
moved.
In order to enable the bar C to move freely in its supports D and to prevent it from?
getting accidentally out of proper position its edges are bevelled and the recesses in
which it slides in the arms are bevelled to correspond.
After the bar C has been drawn outwards into the position in which it is shown in
the accompanying drawings and it is desired to retain it in that position while the
circular head makes a certain number of revolutions it is effected by lowering the a
plate H by means of the handle H³, so that the said plate comes against the inner edge
of the plate J which is fixed to the horizontal bar C by screws J¹.
The plate His free to move on the screw or pivot H2 fixed to the bed of the
machine.
The action of the apparatus is as follows:-
After a desired number of courses has been knitted and the ribbing needles with-
drawn from projecting between the needles in the frame, as is well understood by
operators of this class of machines, the horizontal bar C is drawn outwards, & fixed in
this position as before described.

page_text: This outward movement causes the upper end of the upright bar B to come into
contact with the lug A on the underside of the ribbing dial A¹ and causes the latter to
move on its axis to such an extent as to allow the ribbing needles to intercalate between
the next adjacent frame needles.
One or more courses may now he knitted after which the ribbing dial may be
returned to its original position; this is effected by hand by means of the lever L'
in the arm L. The horizontal bar C may also be allowed to resume its former
position & the work proceed in the usual manner.
Having now particularly described and ascertained the nature of our said Inven-
tion & in what manner the same is to be performed, we declare that what we
claim is
1. In a circular knitting machine, shogging mechanism consisting essentially of a
horizontally sliding bar such as C carrying a post such as B engaging with the
ribbing dial substantially as and for the purpose herein described and illustrated in
the accompanying drawings.
II. In a circular knitting machine, the general arrangement and combination of
parts constituting the complete shogging mechanism operating substantially as herein
described and illustrated in the accompanying drawings.
Dated this 26th day of October 1888.
