WILLIAM JAMES FORD Albany Villa Uppingham Road West Humberstone
Leicester Hosiery Manufacturer. I do hereby declare the nature of this invention
to be as follows:-
That the object of my invention is to adjust and fix the ribb dial to the plain
cylinder, so that the ribb dial cannot move backwards.
To the long needle or plain fabric cylinder I cast or fix a projection on each
side.
To the ribb dial I cast or fix a projection on each side, these projections are
brought together both on one side of the projections on the plain cylinder, to hold
the ribb dial unmoveable.
I allow enough space for the passage of fabric when being made. To the ribb
dial I fix a slide held in its place by a spring. When the plain fabric cylinder is filled
with needles and the ribb needles are required to work between them, I draw back the
slide from working against the projection on plain fabric cylinder.
This allows ribb needles to work over the leaf, in plain cylinder and between
the plain needles.

When a needle is taken out of plain cylinder to make other fabrics, it leaves
more space between the needles. I then press back the slide, which brings the

I, WILLIAM JAMES FORD, of Albany Villa, Uppingham Road, West Humber-
stone, Leicester, 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 :-
This invention has reference to circular reversible knitting machines and embodies
improvements which have for their object to permit of the ribbing dial and ribbing
needles being adjusted in relation to the cylinder and cylinder needles and fixed in
position in such a manner as to prevent any accidental alteration in the relative
positions thereof.
My invention consists of a slide or sliding plate on preferably the underside of
the ribbing dial capable of being slid or projected between a lug on the latter
and a similar lug on the inside of the needle cylinder, and thus adjust and fix
the ribbing dial and needle cylinder in relation to each other as hereinafter
described.

page_text: To enable the invention to be clearly understood, reference is made to the
annexed drawing in which
Figure 1 is a vertical section of so much of a circular reversible knitting machine
as is requisite to illustrate my invention.
Figure 2 is a plan of the underside of a portion of the ribbing dial and showing
also a portion of the needle cylinder in section.
Figures 3 and 34 are plans of a portion of the ribbing dial and needle cylinder
showing the ribbing needles in different positions in relation to the needle cylinder.
A. A. are lugs or projections attached to or formed integrally with the internal
surface of the needle cylinder A' and B. B. are also lugs or projections similarly
connected to the underside of the ribbing dial B'.
The lugs A. A. are both located on one and the same side of the lugs B. B..
To fix the ribbing dial B₁ and its needles C in position relatively to the needle
cylinder A, a nose D¹ or enlarged end of the sliding plate D is projected between
the two adjacent Ings A B on the cylinder and dial respectively.
.
The sliding plate D has a central opening to pass over a projection or down-
wardly extending plate B connected to the boss B³ of the ribbing dial and the
sliding plate D is held in position by a spring plate E or equivalent passing also
over the plate B2 and supported by a screw For the like in the plate B³.
To facilitate the movement to and fro of the plate D it is provided with a handle G
which extends a convenient distance downwardly inside the cylinder A¹ so as to
be readily reached by the operator.
The two diverging ends of the upper part of the handle G are by preference
rivetted or otherwise attached to the sliding plate D. It is obvious that the sliding
plate may be kept in position by other means than those described.
Sufficient space is left between the nose D' (or that portion of the slid passing
g plate
projected between the lugs A B) and the lug B to permit of the fabric he usual
down between the sliding plate and lug and inside the needle cylinder in t
manner.
By sliding the plate between one of the sets of lugs A B the ribbing,
moved in one direction and the opposite movement of the sliding plate c
ribbing dial to turn in a contrary direction.
In most cases the sliding plate is adapted to move the ribbing dial

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :--

ribbing dial and needle cylinder of a sliding plate or equivalent adapted to be
projected between the said lugs substantially as and for the purpose described.
