PROVISIONAL SPECIFICATION.
Improvements in the Construction of Certain Parts used in
connection with Stockinette Knitting Machines.
We FREDERICK TOWNEND of Stanbury near Keighley in the County of York,
Worsted Spinner, and JOHN WILLIAM DYSON of 9 Hillside Villas, Bradford in
the County of York, aforesaid, Manager, do hereby declare the nature of this
invention to be as follows, that is to say
It relates to improvements in the construction of wheels, known as "putting-in,"
"picking-up" and "loop" wheels, that are employed in connection with circular
stockinette knitting machines, and consists of forming these wheels and parts to be
used with them in such a manner that their operations on the needles may be
regulated and altered as desired in order to produce different effects and designs in
the fabric being knitted as may be from time to time found necessary.
Heretofore these wheels, which may be styled "pattern wheels," have had the
required number of interstices between their blades, permanently filled or plugged
up to execute designs for which they were then alone prepared, any other designs
necessitating the use of other specially plugged pattern wheels, however in
accordance with this invention we form the plug-pieces loose or detachable so that
their positions in the wheels may be altered as desired. To hold these plug-pieces
in position the central part of the wheel is made of a suitably dished form to receive
a semi-dove-tailed projecting piece formed on each plug, so that by the bush of
the wheel being made to fit into its place as by being screwed therein or merely
inserted and fastened with supplementary nuts or screws, the projecting pieces on
the plugs will be firmly bound to the side of the wheel and thus the plugs will be
firmly held.

COMPLETE SPECIFICATION.
Improvements in the Construction of Certain Parts used in
connection with Stockinette Knitting Machines.
We, FREDERICK TOWNEND of Stanbury near Keighley in the County of York;
Worsted Spinner, and JOHN WILLIAM DYSON of 9 Hillside Villas Bradford in
the County of York, aforesaid, 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, that is to say :—

putting-in,"
It relates to improvements in the construction of wheels, known as
'picking-up" and "loop" wheels, that are employed in connection with circular
stockinette knitting machines, and consists of forming these wheels and parts to be
used with them in such a manner that their operations on the needles may be
regulated and altered as desired in order to produce different effects and designs in
the fabric being knitted as may be from time to time found necessary.
In the accompanying sheet of drawings
Figs. 1 and 2 are side and edge views of a wheel and its detachable parts made
in accordance with our invention.

page_text: Fig. 3 is a sectional view in perspective shewing the wheel and said detachable
parts, and
Fig. 4 is a transverse sectional view of the wheel and its detachable bush.
Figs. 5 and
are perspective views of the wheel's bush and its nut.
Fig. 7 is side, edge and end view of the detachable part hereinafter described.
In the drawings only one out of the many and varied shapes of pattern wheels is
shewn, since our invention has no reference whatever to the said shape or configura-
tion, however we would have it understood that our invention may be as readily
carried into effect with any other style as with that shewn.
Heretofore these pattern-wheels have had the required number of interstices a,
which intervene between their blades, permanently filled or plugged up to enable
them to execute designs for which they were alone, prepared, for producing in the
fabric under operation and any other designs that were required to be produced
necessitated the use of other specially prepared wheels; however in accordance
with our invention we form the plug-pieces c loose or detachable so that their
positions, as to which of the interstices they shall be placed in or fill, may be
altered as desired.
To hold these plug-pieces c in position the central part of the wheel is dished
or hollowed so as to receive the bent ends of tail-pieces e formed on said pieces c.
In connection with this form of wheel we use a detachable bush having at one of
its extremities a head 9 while its other extremity is screwed to receive the nut k.
When the plug-pieces c are arranged in their proper respective positions on the
wheel, by bushf being inserted therein, as shewn by Fig. 4, and its nut k tightened
or screwed up, its head is brought to press against the tail-pieces e of the pieces c
so that the bent ends of these tail picces e are forced and held into and within the
hollowed or dished part d of the said wheel by which means the plug-pieces c are
held in position, while when they are to be detached for re-arrangement, it is only
necessary to unscrew the nut k and the bushf may be detached.
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 :
1. In combination with a pattern wheel, a detachable plug-piece having one of
its extremities bent to form its means of attachment substantially as specified.
2. A pattern-wheel having a dished or hollowed central part for the reception of
the bent ends of plug-pieces that are to be used in connection with it, plug-pieces
having their extremities formed to fit within said dished or hollowed part, and
means for holding same in connection therewith substantially as specified.
3. A pattern-wheel formed to receive detachable plug-pieces, plug-pieces con-
structed to fit said wheel, and a detachable bush carrying a head at one end and a
screwed nut at the other substantially as specified.
