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:—
This invention relates to the form and construction of wing rings, which I apply
to circular knitting machines. In circular knitting machines on which loose.
circular needle rings or clasps are employed, the said rings are formed to fit
entirely round the cam cylinder, and when it is required to take out any needles
for narrowing or other purpose, the ring in other circular knitting machines must
be taken off, and also replaced upon the needle cylinder before recommencing to
knit, which is a waste of time and inconvenient.
In this invention, the wing ring permits the needles being taken out at any part
of the needle cylinder, without requiring the said ring to be removed from the
machine. I form these wing rings with a hinge or joint, and so constructed as to
open a limited, but convenient distance for the purpose of taking out a needle or
needles, either for narrowing or other purpose. The said ring is fitted upon the
cam cylinder, and being hinged or jointed in a convenient manner remains on the
machine, and only requires opening or closing. I form one or more recesses on
the edge of the ring and bevel the end of one of the closing rings, so that a catch
spring may keep the ring closed, or may hold the ring open firmly any exact
distance, and thus enable the operator to take out the needles more easily.
In the accompanying sheet of drawings illustrating my invention Fig. 1 is an
edge view, and Fig. 2 plan of a semicircular needle wing ring, as herein above
described, applied to a circular knitting machine. a is the cam cylinder b the
needle cylinder, c is the needle wing ring, or semicircular needle wing ring resting
on cam cylinder a: the dotted lines c¹ represent the position of the semicircular
wing ring o when open: the formation of the ends e which strike against outer
part of cam cylinder a when ring is open, limits the amount of opening space: the
spring g falling into recess h retains the ring open as long as required, or keeps it
closed when in recess h¹.
The wing ring c may be made any convenient size, and the joints formed in
any convenient part of the circle of the cam cylinder.

page_text: 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 a circular knitting machine, the formation of a needle wing ring in parts,
to enable the said needle wing ring to open and allow the needles to be taken out
or adjusted, without removing the said ring from the machine, substantially as
.herein before described.
2nd. A needle wing ring, or semicircular wing ring, applicable to a circular
knitting machine, formed; with a joint or other convenient fastening, to enable the
said ring to be opened without requiring to be removed from the machine.
3rd. In a needle wing ring, or semicircular wing ring, the means as herein before
described, whereby a fixed limited distance in which to open the said ring is
obtained.
