PROVISIONAL SPECIFICATION.
Improvements in Knitting Machines.
We, WILLIAM HARRISON, of 242 Plymouth Grove, Managing Director of the
Harrison Patent Knitting Machine Company, Limited, and CHARLES WALLACE
HARRISON, of Gilcrux Villas, Osborne Road, Levenshulme, Secretary of the above
named Company, both in Manchester, in the County of Lancaster, do hereby declare
the nature of this invention to be as follows:-
The invention relates to additional mechanisin applied to knitting machines of
either circular or rectilinear types. The object of this invention is to produce at
any part of the stocking, sock, or other article that is being knitted, an increased
thickness, which is well known as splicing, at those parts most exposed to wear.
In applying our invention to circular knitting machines, we fit around the
cam cylinder an annular ring which has its bearing or holding at the back part of the
machine, and on said ring we place moveable projections which are hereinafter
described:
For the purpose of supplying a supplementary thread to certain parts of the article
being knitted, we fit to the yarn guide or feeder bracket in any suitable position but
preferably on the top side of the yarn guide bracket, a sinall tapered tunnel through
which the supplementary splicing thread is guided before joining the principal thread;
opposite to the entrance or mouth of the tunnel we place a sliding wedge that is
connected to an upright vertical sliding bar attached to the yarn guide bracket, which
when moved up or down presses the wedge slide into the tunnel, or draws it out from
the tunnel thereby breaking the supplementary yarn by wedging it between the
sliding wedge and the inside of the tunnel and holding it there until again released at
a necessary part of the work, when it is drawn into the needles by the main or
principal thread.
The vertical sliding bar attached to the yarn guide bracket obtains its motion by
having a cam fixed to the bottom end thereof, which in the revolving of the
machine comes into contact with the herein before named projections on the annular
ring, causing the said vertical sliding bar an up and down motion, and in turn
causing an in and out movement in the sliding wedge at the top of the yarn guide
bracket.
When our invention is applied to a rectilinear knitting machine such as the
"Harrison "and the "Lamb" type, we fit the splicing appliance on the carriage and
yarn guide, with the projections fitted upon a suitable stationary part of the machine
so as to cause the wedge shaped sliding bar to have an opening and closing motion.

We, WILLIAM HARRISON, of 242 Plymouth Grove, Managing Director of the
Harrison Patent Knitting Machine Company, Limited, and CHARLES WALLACE
HARRISON, of Gillcrux Villas, Osborne Road, Levenshulme, Secretary of the above
named Company, both in Manchester, in the County of Lancaster, 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 additional mechanism applied to knitting machines of
either circular or rectilinear types. The object of this invention is to produce in
those parts most exposed to wear, or at any part of a stocking, sock or other article
that is being knitted an increased thickness which is known as splicing.
We attain this object by the means hereinafter described and as shown in the
accompanying sheet of drawings in which
Figs 1. 2 and 3 are respectively part plan, side and front views of our invention
with so much of a circular knitting machine as is necessary to show the application of
our said invention thereto :
Fig. 4 is a plan of the same drawn to a reduced scale.
In these views similar letters refer to similar parts.
In applying our invention to circular knitting machines we fit around the cam
cylinder a circular or semicircular ring as a which is clamped between the back
portion of the machine and the table.
We attach brackets as a¹ and a² to the aforesaid ring and place therein moveable
projections as e and c' which are retained in the required positions either inwards or
outwards by means of sliding plates as a which are formed with a hole ¹ through
which to pass the aforesaid projections, and fitted so as to slide in the brackets a' and a.
The projections c¹ and 2 are retained in the required positions by sliding down the
plate so that the edge of the hole x' is inserted in one of the grooves a* as shown in
Fig. 5.
For the purpose of supplying a supplementary thread to certain parts of an article
that is being knitted we fit to the yarn guide or feeder bracket d in any suitable
position, but preferably on the top side of said yarn guide bracket, in the position
shown on the drawing, a tapered tube through which the supplementary splicing
thread is guided before joining the principal thread.
Opposite the entrance of said tube we place a sliding wedge g that is connected to
an upright vertical sliding bare attached to the yarn guide bracket which when moved
up or down presses the wedge slide g into the tube for draws it out from said tube by
the action of the angular groove k to which the tail end of the wedge g is connected by
the stud l.
When the wedge g is pressed into the tube f the supplementary yarn is broken by
wedging it between the sliding wedge and the inside of the tube, where it is retained
until again released by the withdrawal of said wedge at a necessary part of the work,
said supplementary thread or yarn being then drawn into the needles by friction with
the main or principal thread.
The vertical sliding bare that is attached to the yarn guide bracket obtains its
motion by having a cam j fitted to the lower end thereof which by the revolving of
the machine comes into contact with the herein before named projections c and c in
the brackets that are fitted on the ring a thereby causing the aforesaid vertical sliding
bar to be raised or lowered and by means of the angular slot or groove / either to
press the wedge g into the tube for to withdraw said wedge.
When our invention is applied to rectilinear knitting machines such as the
"Harrison" and the "Lamb type, we fit the splicing appliance such as herein
before described on the carriage and yarn guide, with projections as c and c¹ fitted

page_text: upon a suitable stationary part of the machine so as to cause the wedge shaped sliding
bar g to have an opening and a closing motion.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1st. In circular knitting machines the use of a splicer that is formed by means of a
tube and wedge fitted to the yarn guide or feeding bracket in any preferred position
by which the supplementary thread or yarn is wedged and broken at certain portions
of the work and reintroduced to the needles by friction with the main thread at
intervals, said wedge being operated by cams or equivalents in combination with
projections as c and c' that are attached to an adjustable ring as a which is held in
position by being clamped between the back portion of the machine and the table, in
the manner and for the purpose substantially as herein before described.
2nd. In rectilinear knitting machines the use of a splicer in which the supplementary
thread is wedged and broken at certain parts of the work and reintroduced to the
needles at intervals by friction with the main thread, said wedge being operated by
cams or equivalents in the manner and for the purpose substantially as herein before
described.
Dated this 30th day of October 1895.
