PROVISIONAL SPECIFICATION.
Improvements in or relating to Circular Knitting Machines.
I, GEORGE FLAD, of Millstone Lane, Leicester, Machinist, do hereby declare
the nature of this invention to be as follows:-
--
This invention has reference to latch needle knitting machines of the circular
reversible type for the production of seamless hosiery and has for its object the
provision of improved means for rendering the action of the needles more certain
than they are at present and of maintaining them in the proper condition to
receive the yarn or thread.
The invention is specially applicable to machines of the type named for the
manufacture of ribbed fabrics in which part of the ribbing needles are withdrawn
from action (as during the knitting of a plain foot bottom and ribbed instep of
a stocking) as after the latches of the needles have been lifted off the hooks by
the latch openers in the usual way some of the latches in consequence of the
vibration of the machine will again accidentally close over the hooks of the
needles, so that the latter cannot take the thread in the next succeeding course
in which they again come into action.
According to this invention I employ brushes or equivalent which may be
connected to any suitable revolving part of the machine and move over the
latches of the ribbing needles or over the tops of the cylinder needles after the
latches have been raised by the latch openers in the usual manner.
The brushes may be of any suitable construction and arranged the one set
at right angles to the other or otherwise to act upon the ribbing and cylinder
needles respectively.

Improvements in or relating to Oircular Knitting Machines.
I, GEORGE FLAD, of Millstone Lane, Leicester, Machinist, 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:→

The invention is specially applicable to machines of the type named for the
manufacture of ribbed fabrics in which part of the ribbing needles are withdrawn
from action (as during the knitting of a plain foot bottom and ribbed instep of
a stocking) as after the latches of the needles have been lifted off the hooks by
the latch openers in the usual way some of the latches, in consequence of the
vibration of the machine, will again accidentally close over the hooks of the
needles, so that the latter cannot take the thread in the next succeeding course
in which they again come into action.
According to this invention I employ brushes or equivalent which may be
connected to any suitable revolving part of the machine and move over the
latches of the ribbing needles or over the tops of the cylinder needles after the
latches liave been raised by the latch openers in the usual manner.
The invention will be understood from the following further description having
reference to the accompanying drawings in which
Figure 1 is a perspective view of sufficient of a circular knitting machine for
the manufacture of seamless ribbed hosiery to illustrate my invention which is
shown as applied thereto.
Figure 2 is a perspective detail of the cam cap, ribbing needle dial and needles
in the latter, drawn to a larger scale than Figure 1 and showing the brush acting
on the ribbing needles.
Figures 3 and 4 are sectional details showing the brushes acting on the ribbing
needles and cylinder needles respectively.
Figure 5 is a sectional detail of the cam cap showing the brush and clamping
plates fixed thereto.
Referring to the drawings A represents the needle cylinder and B the frame
or cylinder needles located in the vertical grooves therein and actuated by cams
in the revolving cau cylinder D in the usual manner.
Crepresents the usual revolving cam cap which has an arm C connected thereto
by a screw C and in the forward end of the said arm there is a perforation C³
in which is tightly squeezed or held a brush C consisting of bristles or fibrous
material and depending downwardly in such a position that the brush covers
or is in contact with the heads or hooks of those needles about to take the thread
and thereby keeps the latches in their lowered position and clear of the needle
hooks.
The cam cap C which as is well understood contains the cams for actuating
the ribbing needles E has let into its peripheral edge two plates F F fixed in
position on the said cap C by screws F.
Clamped between these plates F F is a brush G depending therefrom in such
a manner that it is in contact with the ribbing needles E and serves to keep
the latches down and away from the hooks of the needles as the latter are pro-
jected to take the thread.
The brushes may be constructed and arranged in any other suitable manner
so that they act upon both the frame and cylinder needles for the purpose
described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In a circular knitting machine for the manufacture of seamless ribbed
fabrics the combination of brushes adapted to act on both the frame or cylinder
needles and the ribbing needles substantially as and for the purpose described.
2. In a circular knitting machine for the manufacture of seamless ribbed
fabrics the construction and arrangement of brushes to act upon both the cylinder

described and illustrated in the accompanying drawings.
