Clay, of the same place, Manufacturer.]
I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
George Davidson of Paris, in the County of Brant, in the Province of Ontario,
Canada, Knitter, and William Williams Clay of the same place Manufacturer) and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :--
The object of the invention is to so arrange the needles in the needle-ring that
each needle may be independently removed and replaced without disturbing any
of the other needles in the needle-ring, and which ring is so connected to the needle-
arms that it may be readily removed and replaced by another needle-ring of a
different diameter and it consists essentially of a peculiarly formed needle-carrier
made in sections and having vertical grooves cut in it to receive the needles which
have peculiarly shaped shanks to fit into the said grooves each plate being inde-
pendently secured by a screw-bolt passing through the holding-plate, the needle-
carrier and screwed into the needle-ring which is detachably connected to the
cylinder-arms substantially in the manner as hereinafter more particularly
explained.
Figure 1 is a perspective view partially in section, of this improved device.
Figure 2 is a perspective independent view of the cylinder-arms.
Figure 3 is an enlarged detail of a portion of the needle-carrier in which one
needle is set.
Figure 4 is a detail of the needle.
In the drawing A represents the four cylinder-arms which are connected to the
machine in the ordinary manner. Each of these arms has a groove a through
which the screws B pass in order to enter the screwed holes in the flange of the
needle ring C. By forming the slots a in the arms A it will be noticed that I can
readily remove the needle ring C and replace it with one of a different diameter
but as the screws B might not secure the ring O with sufficient rigidity I place on
[Povice 671

flange of the needle-ring C.
D is a needle-carrier made as indicated in Figure 1 in sections so that it can be
readily removed and replaced when necessary. On the inside of the needle-
carrier D I form a projection of wide rib d to fit into a recess made to receive it
and formed in the ring C. On the outside of the needle-carrier D, a series of
vertical grooves e are made to receive the shanks of the needles which shank
being made a snug fit of its respective groove all of which are exactly the same
size and shape so that the needles are interchangeable. The end of the shank fis
bent as at g so that when the shank is fitted into its groove e its bent end g will
fit into a notch made in the bottom side of a shoulder i made in the outside of
the carrier d at the base of the slots. In fitting each needle into its groove the
end g is first slipped into its notch h. The shank f is then pressed into its notch
and the bevelled shoulder j formed on the shank butts against the top edge of
the needle carrier D and the needle is thus rigidly held from moving in either
vertical directions.
When the needles are placed in position the holding plates E are put on separately
and are secured in position by the screw-bolts F which pass through holes in the
plate E and carrier D and are screwed into the needle ring C. When thus screwed
in the plates E hold the needles rigidly in position.
From this description it will be seen that by merely removing one of the plates E
any single needle can be removed and replaced by another without disturbing any
of the other needles in the needle ring.
It will be noticed on reference to Figure 1 that a groove is cut on the inner face
of the holding plates E to receive the shoulder i when the said plate is screwed into
position.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is :-
1. The cylinder-arms A having the grooves a made in them in combination with
the detachable needle ring C secured in position by the screws B and holding-pins b
substantially as and for the purpose specified.
2. The needle-ring C secured to the cylinder-arms A and having a groove formed
on its outside to receive the wide rib d. formed on the needle-carrier D the grooves c.
made in the said needle-carrier D to receive the shanks f of the needles, in
combination with the detachable holding plates E secured by the screw bolts F
substantially as and for the purpose specified.
3. The needle-carrier D made in sections and having vertical grooves e formed
in it and a projecting shoulder or rib i made near its base in combination with the
holding plates E secured by, the screw-bolts F and having grooves cut on their
inner side to receive the shoulder i substantially as and for the purpose specified.
4. A knitting machine needle having a shank f with a bent end g and a bevelled
shoulder in combination with a needle carrier D having a slot e to receive the
shank fand a notch to receive the end g substantially as and for the purpose
specified..
