Improvements in Knitting Machinery.
We THE NOTTINGHAM MANUFACTURING COMPANY Limited of Station Street in
the Town and County of the Town of Nottingham and JOHN GROVES of 4 Burton
Street, Loughborough in the County of Leicester, Manager, and JAMES WHATNALL
of 27 School Street Loughborough aforesaid, Mechanic, both in the employment of
the said Nottingham Manufacturing Company Limited do hereby declare the nature
of this invention to be as follows :-
These improvements have relation to means for increasing the facilities for the use
of points or instruments coöperating with the needles in knitting machinery, whereby
those points or like instruments may more readily and economically be brought into
and taken out of operation in the machine.
In knitting machinery as at present constructed the points or like instruments are
laid in grooves or slots in a holder, sometimes called a finger. each slot being of sub-
stantially the same diameter as the portion of the instrument laid therein to be held,
a bent portion passing down into a hole at right angles to the slot to prevent turning
and the whole set of needles for the time in use are locked down into position by a
covering plate fastened by a screw bolt passing through it into the lower slotted
holder, and in order to vary or alter the number of points or like instruments for the
moment in operation it is necessary to stop the machine and remove the screw
plate, and superfluous Points, replacing the Points required, and so on, each time
with great loss of time, and trouble.
According to our invention we avoid these inconveniences and render the changes
of numbers of Points desired to be used at any time without necessarily stopping the
machine by forming the holder for the points or like instruments with the tail pieces,"
stems, and grooved points so as to slide more or less within the slots or grooves in the
holder so that as required any portion of a set may be protruded or withdrawn
out of use by merely pressing on the projecting tail in a forward or backward
direction.
To prevent too free movement of the points or instruments when in operation
friction is put thereon by interposing between the covering plate and the under part
of the holder a pad or layer of vulcanised india rubber, leather or other suitable
packing, and the amount of pressure can be regulated by means of the screws holding
the two parts together.
To facilitate sliding of the points it is well to make the whole of substantially the
same diameter.

Improvements in Knitting Machinery.
We THE NOTTINGHAM MANUFACTURING COMPANY, Limited of Station Street in
the Town and County of the Town of Nottingham, and JOHN GROVES, of 4 Burton
Street, Loughborough in the County of Leicester, Manager, and JAMES WHATNALL
of 27 School Street, Loughborough aforesaid; Mechanic, both in the employment of
the said Nottingham Manufacturing Company Limited, 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 :-
•
These improvements have relation to. means for increasing the. facilities. for the use.

page_text: Fig. 1 is a side view.
Fig. 2 is a front view, and
Fig. 3 a plan view, of a holder, herein shown as for holding four points 1, 2, 3, 4,
the points 1, 2 and 3 being protruded ready for use, whilst number 4 is shown drawn
back in the groove 8 out of use.
Figs. 4, 5, 6, 7 and 8 are detail views.
a is the main portion of the holder or finger, which is slung on its operating rod
by the sleeve a', and secured in place by the screw b. This holder a is formed with
grooves, herein shewn as four in number, 5, 6, 7 and 8, in which are laid the
points 1, 2, 3 and 4, said points being retained therein by the covering plate c, held
to the part a² of the holder a, which is recessed accordingly, by the screws c¹, c². The
form of the grooves 5, 6, 7, or 8 of the recessed part a of the holder a will be best
seen by reference to Fig. 5, which indicates in cross section the holder a.
The shape
of the covering plate c is shewn in Fig. 4, wherein it is in plan, and Fig. 6 wherein
it is in edge view. Fig. 7 shews the thickness of the india-rubber, or elastic pad or
layer d, which is interposed between the plate c and the part a². In Fig. 8 one of
the points is shown separately.
As in practice one point may sometimes be in use, at other times two points, at
other times three, four or other number, according to circumstances, the present
invention gives great facility for these changes being rapidly effected by simply
sliding the points to or fro in their holder as explained without stopping the frame
as previously was the necessity.
To prevent too free movement of the points or instruments when in operation
friction is put thereon by interposing between the covering plate c, and the under
part of the holder a, a pad or layer d of vulcanised india-rubber, leather, soft
metal, or other suitable packing or pad, and the amount of pressure can be regu-
lated by means of the screws c¹, c² holding the two parts a and c together.
To facilitate sliding of the points in their grooves 5, 6, 7 and 8, it is well to
make the whole length of each point substantially the same diameter throughout.
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. Holders for points, and points for operating therewith, for use in knitting
machinery, constructed and operating as set forth.

page_text: 2. In knitting machinery the construction and use of holders for the points or
like instruments with tail pieces, stems and grooved points, adapted to slide in
slots or grooves so that as required any portion of a set of points may be protruded
for, or withdrawn from, use as set forth.
