Improvements in Circular Knitting Machines.
1,JAMES HIGHAM, of 127 Stretford Road, Manchester, in the County of
Lancaster, Manager, do hereby declare the nature of this invention to be as
follows:-
"
This invention relates to circular knitting machines such as are employed in the
production of either ribbed or plain knitted fabrics.
The object of this, invention as to construct a machine in which the adjustment
of the ribbing arm, and the height of the ribbing dial will be facilitated, and the
steadiness of the ribbing arm when in position will be increased: the placing of the
thread on the book that carries the yarn from the yarn stand to the feeding eye is
more easily effected: the action of the latch guide is improved: the bearing for the
spindle that carries the gear wheel and handle is extended, and the mode of
applying power is simplified: I attain the above object by the means hereinafter
described and as shown in the accompanying sheet. of drawings which for the
purpose of describing my invention more clearly, illustrates the parts to which
reference has been made.
In this invention I construct the column a which supports. the ribbing arm with
a boss,b, in which is a groove or slot c as shown by the plan view Fig. 1 and side
view Fig. 2.
:
I form the rear end of the ribbing arm Fig. 3 with a spindle as d' that
is turned 'so as to fit into the hole e in the column a and that will slide therein :
I place a loose collar on the spindlé,d', said collar being formed with a flange g
that will fit accurately into the groove c.
}
When the position of the cam post has been perfectly adjusted relatively with
the cam cylinder the aforesaid 'collar is rigidly and permanently affixed to the
spindle by means of a screw or pin f¹: The ribbing arm may at any time by
these means be lifted out and replaced without altering the relative central position
of the cam post with the cam cylinder.
.
In order to obtain vertical adjustment of the ribber dial, and as a means of "
indicating the extent of said adjustment I pass a screwed spindle d' through the
aforesaid spindle.d¹: The spindle d² is, surmounted by a finger piece or cap d³ :
Under said cap'l fit a loose ferrule d that will permit the spindle d² to, revolve
thereip, but will not itself. revolve: connect this ferrule to the central portion of
an indicator' as; Fig. 4. by means of the pin j¹, one end of said indicator being
fixed, and the opposite end being free to be moved by the rise and fall of the
ribbing. arm d which is effected by turning the cap or finger piece d³ thereby,
raising and lowering the ribber dial and indicating the extent of movement on the
indicator plate j².

I place the hook that carries the yarn from the yarn stand to the feeding eye
below the bearing and outside on the ribber cam post which is passed through the
ribber arm: The ribber 'dial and cam plate are secured to the cam post by means
of a 'dial stud passing through the lower portion of the cam post : The cam post.
takes its bearing on the ribber arm: 'I construct the ribber latch guide in the
manner represented in Figs. 5 and 6 the guide slides vertically in the grooves m
and, and by these means adjusts itself to the height of the needles at whatever

needles.
I construct a duplicate bearing for the spindle that carries the gear or driving
wheel and handle, by forming a second bracket on the inner portion of the
underside of the bed of the machine, and placing the gear wheel between said
brackets.
On the boss extending from the outer bracket, and between the handle and said
bracket, I place a loose pulley over which a strap or cord is passed from a counter
or driving shaft: I form projections on the side or arms of said pulley, and
corresponding stops on the back or inside of the handle: Power is applied by
moving the aforesaid pulley along the hoss of the bracket until the before named
projections engage with the projections on the handle: When the power is
required to be withdrawn, the pulley is switched back until free from the bandle,
when it will run as a loose pulley.
For machines driven by power the bed is constructed so as to place the driving
handle at right angles with the working bench.

I JAMES HIGHAM of 127 Stretford Road Manchester in the County of
Lancaster Manager 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 relates to circular knitting machines such as are employed in
the production of either ribbed or plain knitted fabrics.
The object of this invention is to construct a machine in which the adjustment
of the ribbing arm and the height of the ribbing dial is facilitated and the ribbing
arm when placed in position is rigidly retained; the operation of placing the
thread on the hook that carries the yarn from the yarn stand to the feeding eye is
more easily effected; the action of the latch guide is improved; the bearing for
the spindle that carries the gear wheel and handle is increased; and the mode of
applying power is simplified.
I attain the above object by the means hereinafter described and as shown in the
accompanying sheet of drawings in which-
Fig. 1 is a side view and Fig. 2 a front view of a circular knitting machine
constructed according to my invention.
Figs. 3 to 7 are parts of the same machine shown separately in order to explain
more clearly the improvements constituting my invention.
In the several views shown similar letters refer to similar parts.
In this invention I construct a column a which supports the ribbing arm with a
boss in which is a groove or slot c as shown by the plan view Fig. 3 and side
sectional view Fig. 4 I form the rear end of the ribbing arm d with a spindle
as d', Fig. 5, that is turned so as to fit into the hole e in the column a and will
slide therein I place a loose collar f on the spindle d' said collar being formed
with a flange g that will fit accurately into the groove c or the groove may be in
the collar and the flange on the boss. When the position of the cam post has
been perfectly adjusted relatively with the cam cylinder the aforesaid collar fis
rigidly and permanently affixed to the spindle d' by means of a screw or pin f' the

page_text: ribbing arm may at any time be lifted out and replaced without altering the relative
central position of the cam post with the cam cylinder.
In order to obtain vertical adjustment of the ribber dial and as a means of
indicating the extent of said adjustment I pass a screwed spindle d2 through the
aforesaid spindle d' as in Fig. 5. The spindle dis surmounted by a finger piece
or cap d³. Under said cap I fit a loose ferrule as d' that will permit the spindle
to revolve therein but will not itself revolve. I connect this ferrule to the
central portion of an indicator as j by means of the pin one end of said
indicator being pivoted on a pin and the opposite end being free to be moved
by the rise and fall of the ribbing arm d and the column a which is effected by
turning the cap or finger piece d³ thereby raising and lowering the ribber arm d
and the dial d and recording the extent of movement on the indicator plate j.
I place the hook k that carries the yarn from the yarn stand to the feeding eye
below the bearing and outside on the ribber cam post 7. I form a solid collar r on
the cam post and pass said cam post through the ribber arm. The cam post is
flattened on one side on the part that projects below the ribber arm; the hook k is
fastened to the flattened portion opposite the aperture as in Fig. 6 thereby
permitting the yaru to pass through said hook without coming in contact with the
interior edge of the cam post.
I form a slot v in the ribber arm and a corresponding slot v in the cam post
through which the yarn may be passed and readily threaded through the hook k.
The ribber dial d and cam plate are secured to the cam post by means of a dial
stud passing through the lower portion of the cam post, the head of said stud
resting on a shoulder t within the cam post. The cam post takes its bearing on
the upper surface of the ribber arm by means of the collar r.
I construct the ribber latch guide in the manner shown in Fig. 7. The guide
slides in the vertical grooves 'm and m³ and adjusts itself to the height of the
needles at whatever position or height the dial may be raised or lowered by trailing
over the ribber needles.
In a modification I pivot the latch guide to the yarn carrier so that said latch
guide may trai! over the ribber needles.
I construct a duplicate bearing for the spindle that carries the gear or driving
wheel and handle by forming a second bracket on the inner underside portion of
the bed of the machine, and placing the gear wheel y between said brackets. On
the boss extending from the outer bracket a and between the handles and said
bracket I place a loose pulley 2 over which a strap or cord is passed from a
counter or driving shaft. I form the projections on the side or arms of said
pulley and corresponding stops u' at the back or inside of the handle s. Power is
applied by moving the aforesaid pulley along the boss of the bracket ¹ by means
of the bell crank lever at until the before named projections engage with the
projections on the handle. When the power is required to be withdrawn, the
pulley is switched back until free from the handle's when it will run as a loose
pulley.
For machines that are driven by power the bed is constructed so as to place the
driving handle at right angles with the working bench.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is-
In circular knitting machines-
1st. The fixing of the ribber arm to the column that supports said ribber arm by
means of an adjustable collar as f in which either a groove or a flange as g is
formed so as to fit in a boss that is formed with either a flange or a groove
as c at the upper end of the column that carries the ribber arm in the manner and
for the purpose substantially as hereinbefore described.
2nd. The means employed for obtaining vertical adjustment of the ribber dial

page_text: by the use of a screwed spindle as d² and in combination therewith an indicator as j
for the purpose and in the manner substantially as herein before described.
3rd. The use of a cam post as q in which is an aperture as k¹ and a groove or
slot' v! said cam post being flattened on one side below the ribber arm with the
hook for the yarn secured thereto and opposite the aforesaid aperture substantially
as and for the purpose herein before described.
"
4th. The use of a cam post in which is a slot as v¹ in combination with a slot
as formed in the ribber arm through which to pass the yarn and constructed with
a bearing as, for the purpose and in the manner substantially as hereinbefore
described.
5th. The use of a ribber latch guide that will rise and fall by trailing over the
needles in the manner substantially as herein before described.
6th. A duplicate bearing as a and al and in combination therewith the use of a
pulley that is fitted on the boss of one of the aforesaid brackets so as to slide
thereon and having studs or other projections formed to engage; in projections on
the handle that is fitted on the shaft carrying the gear wheel by which said pulley
may run either as a fast or as a loose pulley in the manner substantially, as
hereinbefore described.
"
7th. A pulley on which studs or projections are formed to engage, with studs or
projections on the handle that is fitted on the shaft carrying the gear wheel and by
which said pulley may run either as a fast or as a loose pulley, in the manuer and
for the purpose substantially as herein before described.
8th. A circular knitting machine that is constructed substantially as and for the
purposes hereinbefore described.
