Improvements in Circular Knitting Machines.
JOHN WHITE of 67 Southwark Street St. Saviours Southwark in the County of
Surrey, Manufacturer, THOMAS GEORGE LESTER MILLER of 67 Southwark Street
aforesaid Engineer, and FRANCIS THOMAS PINSON of 67 Southwark Street aforesaid,
Mechanic, do hereby declare the nature of this invention to be as follows:-
Our invention relates to Circular Knitting Machines and is not adaptable to any
other form of knitting machine.
One part of our invention consists of a cylinder with increased external circum-
ference or taper at the base by means of which a cylinder of a reduced internal
diameter can be introduced on any given machine producing seamless looped fabrics
such as bosiery in tubular or flat forin.
A machine fitted with our improved cylinder is capable of knitting a plain or ribbed
web which may be flat or tubular widened or narrowed.
In all existing circular knitting machines there is no provision for making tubular
& seamless hosiery and other looped fabrics of reduced diameters on the one machine
and it was necessary previous to our invention to have a separate machine for each
diameter.
Another part of our invention relates to a knitting machine needle specially formed
with increased length of butt at its buso.
Our invention also provides for an adjustable yarn guide and needle latch opener
sliding to or from the centre of a machine and held at any given point by means
of a stud and nut.
Hitherto yarn guides have been fixed and not adjustable centrally.
Further another part of our invention provides for an adjustable dial post
moving centrally, such post to travel on a slide and to be held in any given
position by means of a stud and wing nut or, to be actuated by a spiral or flat
spring and set screw. In all existing machines the dial post is adjustable circum-
ferentially only.
Full details and complete set of drawings will be found in the Complete
Specification.

COMPLETE SPECIFICATION.
Improvements in Circular Knitting Machines.
We, JOHN WHITE, Manufacturer, and THOMAS GEORGE LESTER MILLER,
Engineer, and FRANCIS THOMAS PINSON, Mechanic, all of 67 Southwark Street,
n the County of Surrey, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
scertained in and by the following statement:-
Our invention relates to circular knitting machines and is not adaptable to any
ther form of knitting machine.
And in order that our invention may be thoroughly understood, we now proceed

page_text: to describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1 represents a sectional view of the cylinder a with extended base a fitted
to the knitting machine, also in elevation is described the adjustable carrier b, with
the base platen partly in section.
Figure 2 denotes an elevation of the cylinder a, and extended base a¹ with a section
between the grooves.
Figure 3 is a plan of the top of figure 2, with a portion of the grooves described.
The cylinder is provided with 60 grooves in the circumference.
Figure 4 represents an elevation of the standard c, with the slotted plate kat
right angles to the standard, the dotted lines indicate the slot; and the bottom view
of the slotted plate k is described in this figure.
Figure 5 denotes the plan of the top of the carrier b and the plate d.
Figure 6 is an elevation of the back of the carrier b, with a plate d, and a tenon f
fitted in the slot m and secured by a set screw e.
The carrier b at the base is
provided with a slot g in a tenon for the purpose of being adjusted in a groove
in the standard i, by the set screw h. At the base of the standard h a curved
plate n is formed with ears j,j, drilled and countersunk, in order to fix the same to
the base of the machine.
Figure 7, is a section on line A, B, of figure 6.
One part of our invention consists of a cylinder a, with increased external circum-
ference a¹, or taper at the base, by means of which a cylinder of a reduced internal
diameter can be introduced on any given machine producing seamless looped fabrics
such as hosiery in tubular or flat form.
A machine fitted with our improved cylinder a, figure 1, is capable of knitting
a plain or ribbed web which may be flat or tubular, widened or narrowed in
any part.
Previous to our invention there was no provision in circular knitting machines
for employing cylinders of more than one diameter, and it was necessary to have
a separate machine for each diameter of cylinder.
The needles a² are operated in the ordinary way but have an elongated butt a³
to correspond to the extended base a¹ of the cylinder a, which enables the cams to
act upon the same.
Our invention also provides for an adjustable yarn guide or carrier and needle
latch opener b, sliding to or from the centre of a machine and held at any given
point by means of a stud and nut or screw h. The yarn guide or carrier can be
made adjustable at the base or other part of the standard in the same or similar
manner as herein before described. Hitherto yarn guides have been fixed and not
adjustable centrally.
Further another part of our invention provides for an adjustable dial post c
moving centrally, such post to travel on a slide and held in any given position by
means of a set screw or a stud and wing nut ; or to be actuated by a spiral or
flat spring, and such spring to be held fast at one end to the base of the post as
indicated by dotted lines in figure 1. Where the spring is used the vertical post c
will be hinged to the horizontal base k and indicated by a dotted circle in figure 1.
In existing machines the dial post is adjustable circumferentially only.
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
First. The combination of the cylinder a and a', fitted to the base of a circular
knitting machine, substantially as herein described and according to figures 1, 2,
and 3.
Secondly. The combination of the adjustable carrier b, with the slot g in the tenon,
for the purpose of sliding in a groove in the standard i, and the standard i screwed

page_text: to the base of a circular knitting machine, substantially as herein described and
according to figures 1, 5, 6, and 7, of the accompanying drawings.
Thirdly. The combination of an adjustable dial post c, with the slotted plate k,
fixed by the stud and wing nut 1, to the base of a circular knitting machine,
substantially as herein described and according to figures 1, and 4, in the accom-
panying drawings.
