page_text: I, WILLIAM HARRISON, of 128 Portland Street, Manchester, in the County of
Lancaster, and 67 Oxford Street, London, Patentee and Manufacturer, do hereby
declare the nature of my said invention to be as follows:-
The object of this invention is to produce plain or ribbed knitting by the juxta-
position of a grooved vertical needle and horizontal cylinder The horizontal
cylinder or ribbing disc will knit simultaneously with the vertical cylinder. The
ribbing disc can be removed instantly for plain knitting. I suspend the ribbing
disc in the centre of the vertical knitting cylinder. The disc is secured to a central
stud which is shouldered part way the upper end terminates with a screw thread
the disc stud is passed up the head of the arm which holds the, ribbing disc and
stud which is secured by an adjusting nut and a lock nut-When the adjusting nut
is unscrewed it forcibly causes the ribbing disc to move upwards or downwards so
that the disc ribbing needles may be exactly adjusted to the suitable position of
the vertical cylinder needles. This I accomplish by making the adjustable disc nut
with a shoulder on the upper side and an enlarged flange on its under side-which
is preveously passed through a cap ring. The lower part of the.cap ring is fastened
to the head of the arın. I also accomplish the same result without the flange
(although the flange is the most preferable) by making a hole way in the lower
part of the cap ring to screw two studs, pins, or screws into the lower end of the
disc adjusting nut so that they will be opposite the one to the other progecting
outwards. The flange or the two studs-pins or screws will act as internal shoulders
against the underside of the cap ring, thus with the adjusting ribbing disc nut
shoulder on the upper side the cap ring is secured between the lower and upper
shoulder of the adjusting ribbing disc nut which revolves while keeping one
position without rising upwards or downwards, but when turned causes the disc
stud or shank to forcibly rise upwards or downwards which is then made fast by
an upper lock-out. The knitting being put into position with the ribbing needles
out of action an opening cam door throws them into motion by the cams within
the cap and the ribbing and ordinary needles knit together, producing circular
ribbed web any desired length of stocking, before fashioning the heel, the ribbing
needles must be drawn out of action by the closing cam door within the inner
grooves of the said cap also one half more or less of the loops on the ribbing needles
are removed and placed on the ordinary needles by hand the cylinder is then
reversed half way. As the dog recedes from a projecting pin the cap does not

page_text: move; the ordinary needles, with the ribbing loops thereon, continue to knit plain
until the heel is formed, then again ribbed work may be knitted again when the
opening cam door throws the ribbing needles into the outer grooves of the cap
and between the ordinary needles; by turning the cylinder until the dog strikes
the pin the cap will again revolve, and both needles will again knit. When the
toe is finished another stocking may be commenced without breaking the thread
by making another welt.
Improvements in Stocking Knitting Machines.
I, WILLIAM HARRISON of 128 Portland Street, Manchester in the county of
Lancaster and 67 Oxford Street, London Patentee and Manufacturer do hereby
declare the nature of my invention for IMPROVEMENTS IN STOCKING KNITTING
MACHINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of this invention is to produce plain and ribbed knitting, by needles
working vertically e Fig. 1 and a radial disc d suspended from a spindle terminating
with a screw at its upper end on which to place a nut formed either with or without
flanges, for the purpose of raising and lowering the said disc and thus adjusting
the ribbing needles with the vertical cylinder needles.
In the accompanying sheet of drawings the ribbing disc is suspended in the
centre of the vertical cylinder Fig. 1: d the disc is secured to stud f Fig. 3 which
has a shoulder at the top: the upper end terminates with the screw thread f¹ Fig. 3.
This disc stud f Fig. 3 is passed up the head / Fig. 1 which is secured by the
adjusting nut and lock nut m; when the adjusting nut is unscrewed or screwed
forcibly it causes the disc to move upwards or downwards as required to suit the
position of the vertical cylinder needles exactly; I accomplish this by making
adjusting nut with a shoulder ¹ on the upper side and shouldered or made with a
flange on the under or internal side of the cap ring ; and j¹ Fig. 3.
The lower part of the cap ring is secured by two screws / to the head of the
arm 2: The underside or internal shoulder I make in shape of a flange, or two
projecting pins or screws which take hold of the underside of the cap ring j¹ and
so prevents the adjusting nut 7 Fig. 3 from traversing up or down and so when it
is turned the disc stud f is forced up or down and thus adjusts the ribbing disc:
the cap ring and would also move up and down with the adjusting nut if not
screwed fast by screws to the head of the arm z.

page_text: Fig. 3 shows the internal working of Fig. 1: Fig. 4, v and u shows how the
ribbing disc can be adjusted to right or left when the lever handle 2¹ is moved up
or down, the vee swell will bear against lug u and so push it further back for
adjustment to the needles.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st. In combination with the cylinder knitting machine the method described
of raising and lowering the ribbing disc of a circular knitting machine for the
adjustinent of the ribbing needles to the ordinary cylinder needles.
