JOHN CHARLES MOORE Hosiery Machinist 18 Crafton Street, Leicester in the
County of Leicester do hereby declare the nature of this invention to be as
follows:-
The first part of this invention consists of an improved transfering apparatus
which will transfer Rib tops, Hose legs and the like upon the needles of a circular
knitting machine with absolute certainty and in less time than any existing
method.
This device is so arranged that when placed in position and quite clear of the
needles by pressing the tube or its equivalent it slides downwards and the transfer
points cover every needle in the machine absolutely, thus avoiding all possibility
of drop stitches that occur when using transfer devices of the ordinary kind.
This result is obtained in the following manner. In conjunction with a transfer
device of an ordinary character which has a tube, or its equivalent extending on one
side and on the opposite side transfer points are fixed in the same. I now fit an
outer ring, or cylinder which is constructed in such a manner that it is capable of
sliding upon the aforesaid tube and over that part which contains the transfer
points. A section, or the whole of this part of the outside ring that passes over the
transfer points is now cut to suit the gauge of machine, a slot, or its equivalent
is also cut upon one side which allows a key that is fitted upon the transfer device
to hold it in position and admits of the same sliding parallel over each other, this
outside cylnder, or ring is now placed upon the cam cylinder of machine that
contains a projecting ring or other suitable arrangements to hold the same central
with machine and the aforesaid cut part of this outside ring passing over those
Sinkers, or holding down bits, or their equivalent which extend beyond the needle
cylinder, at the same time the transfer proper is held quite clear of the machine
needles and upon the upper part of this ring, and when this apparatus is placed
by the operator in this position on the machine, it is both parallel, central and
correct to the gauge of same, and by placing the hand upon that part of the transfer
device which extends through the outside ring and pressing the same it will
immediately fall over the whole of the needles in the machine and by these means
the Top or lose leg is transfered simultaneously & correctly.
The second part of this invention is an arrangement for inserting an extra thread
of yarn in those parts of Stockings and the like that may be required such as heels
and toes with absolute certainty, and is performed in the following manner;
In combination with a yarn trapper, or breaking off device, I arrange two sliding
friction arms which slide in opposite directions by means of a small pinion wheel,

page_text: or its equivalent, that is fixed in position to operate upon the same, the slides are
now controlled by a lever or its equivalent which is attached to the yarn guide
bracket and derives its motion from a suitable cam fitted upon the lower part of
machine, when this lever is brought into action it causes the slides to move in
opposite directions and the yarn and splicing thread being located between the ends
of these slides which pass through a slot, it deliberately twists them together thus
causing the splicing thread to immediately pass along with the ordinary yarn to
the needles of machine, this is then broken off by a trapper, or equivalent device
conveniently fixed in position for the purpose.

COMPLETE SPECIFICATION.
Improvements in Appliances applicable to Circular Knitting
Machines.
JOHN CHARLES MOORE Hosiery Machine Builder 18 Crafton Street Leicester in
the County of Leicester 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 consists of an improved transfering apparatus which will transfer
rib tops, Hose legs and the like upon the needles of a circular Knitting Machine
quickly and with absolute certainty.
The device is so arranged that when placed in position and quite clear of the
needles, by pressing the tube, or its equivalent that projects through the guide
ring, or bracket, it slides downwards and the transfer points cover every needle in
the machine absolutely, thus avoiding all possibility of drop stitches that occur
when using transfer devices of the ordinary kind.
I obtain this result in the following manner. In conjunction with a transfer
of an ordinary character which has a tube, or its equivalent extending on one
side and upon the opposite side transfer points are fixed in the same, I now fit
upon the outside of this transfer a guide ring, cylinder, or bracket of special con-
struction that is capable of sliding upon the aforesaid transfer and over that part
which contains the transfer points. A section or the whole of this outside guide
ring, or bracket that passes over the transfer points is now cut to suit the gauge
of the machine, a slot or its equivalent is also cut upon it, which allows a key that
is fitted upon the transfer to hold it in position and admits of the same sliding
parallel over each other, this guide ring, or outside cylinder is now placed upon the
cam cylinder of machine that contains a projecting ring, or other suitable arrange-
iment to hold the same central with the machine and the aforesaid cut part of this
outside guide ring passing over those sinkers, or holding down bits, or their
equivalent which extend beyond the needles in the cylinder of the Machine, at the
same time the transfer proper is held quite clear of the Machine needles and upon
the upper side of the outside guide ring and when the apparatus is placed by the
Operator in this position on the Machine it is parallel, central, and correct to the
gauge of same, and by placing the hand upon that part of the transfer device which
extends through the outside guide ring, and pressing the same down it will
immeadiately fall over the whole of the needles in the machine. And by these
means the rib top or Hose leg, is transfered simultaneously and correct.

page_text: A modification of the foregoing device would be to arrange the outside guide
cylinder, ring, or bracket so that it could be quickly placed in position by resting
upon suitable supports fixed upon the bed of Machine (in place of having the slots
cut to pass over the Sinkers) or their equivalent but any modification of this
character I claim are equally applicable for the purposes of this invention.
In order that the foregoing specification may be more readily understood, I will
now proceed to describe the drawings of same.
Fig. 1 is an elevation of the transfer device.
Fig. 2 & plan of the same.
Fig. 3 is a section of the transfer device.
Fig. 1 Shews the position of the quills or transfer points (a few of which are
here shewn at A) when the apparatus is in position for receiving the rib top, or
Hose legs previous to being transfered to the Machine, the device for this purpose
is placed upon a pedestal that fits upon the end of tube at, B, the instrument then
by its own weight causes the inside part to slide so that the quills or points project
quite clear of the outer guide ring and convenient for the operator; a rib top or
Hose leg is now placed upon the quills, or points of the device the loops of which
are pressed down the points as far as possible; the operator will now lift it off the
pedestal by holding the outside guide ring, or bracket, this will cause the inside
tube that contains the points and rib top, or Hose leg to immeadiately fall inside
the outer guide ring and assume the position as shewn in Fig. 3, which is a
sectional view of same.
The method which allows the inside tube, or transfer device proper, to slide
freely and parallel to the outer guide tube, or bracket is shewn at Fig. 1, a, being
the key fitted upon the inside transfer part and b the slot cut in the outside guide
tube, or bracket that controlls the same.
Fig. 3 is a sectional view of the transfering device and is here shewn in the
crrect position ready for placing upon the Machine, the loops of the rib top, or Hose
leg are here supposed to be upon the points A and are pressed as far up the points
as possible; Tricks or slots are cut upon the edge of the outside guide ring, or
bracket as shewn at, C, these tricks, or slots are cut exact to the gauge of the
Machine and may be cut alround if necessary, but in the present instance only a
section is required as here shewn, and by placing the instrument over the Machine
needles so that these slots fall over the Sinkers, or their equivalent and at the same
time the outside edge of the guide ring at, 1), falls into a recess that is formed
upon the upper side of the frame cam ring or its equivalent; it immeadiately
adjusts the device so that the points are in a parallel line with the needles of
machine, and by the operator pressing down the inside tube a the point, B, Fig. 3,
it will cause the points of the instrument that contains the loops of the top, or
Hose leg to cover each needle in the Machine and by these means the Hose leg, or
rib top, is transfered from the device to the needles of the Machine simultaneously
and correct.
Fig. 2, is a plan of the device shewing the whole of the transfer points, or quills
also the slots cut in the outside guide ring and the method of holding same so as to
slide parallel by means of the slot and key at, a.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination of a transfer device, with a guide ring, cylinder, or bracket;
substantially as illustrated and described.
2. The combination of a transfer device, with a guide ring, cylinder, or bracket
arranged so as to be adjustable upon supports that are attached to the Bed of
Machine or its equivalent; while transfering takes place substantially as and for
the purpose specified.

page_text: 3. The applicability of the foregoing device substantially as specified for the
purpose of transfering all the necessary rib parts to circular Knitting Machines in
the Manufacture of Half Hose, Hose, Socks, Shirts, Pants, and such like articles
