IMPROVEMENTS IN CIRCULAR KNITTING MACHINES
Year: 1884

page_text: I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A., of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool, in. the County of Lancaster, and of 323 High
Holborn, in the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said invention for "IMPROVEMENTS IN CIRCULAR KNITTING MACHINES "
(a
communication from abroad by Rafael Stahl, Stuttgart, Wurttemberg, Germany) to
be as follows:-
In the controlling or actuating mechanism for circular knitting machines, the
mesh forming eccentric or device is applied in such a manner, that it exerts a down-
ward pressure on the backs of the guide discs of the plates on that side of the
plates facing inwards or towards the article being woven or knitted; or a third
annular guide disc is applied, through which the arm of the eccentric passes, so
that the eccentric exerts a pressure on the plates between the guide discs or on the
outer side of the plates, and always on that portion of the same which faces the
needles. Whereby frequently a lateral strain is exerted upon the plates and
thereby a bending of same is occasioned.
The object of this invention is to obviate these objections and at the same time,
with ease and convenience, to superintend and control, from outside, the proper
working of the plates (between the needles). The eccentric or device which
actuates these plates is adjusted so that it no longer lies between or behind the
guide-discs, but is placed or situated outside the guide-discs, and does therefore,
coming in contact with them outside of their fulcrum, act on the plates from below
by raising the heads of same, so that to the other (hooked) ends of the plates
is imparted a downward motion between the needles with great regularity and
safety.
In order to bring about a correct dropping of the plates there is here situated a
spindle similar to what is used in other machines by the German manufacturers of
circular knitting machines technically termed a "Bügel" that is, flat iron.
The eccentric or controlling device of the plates is connected to the frame-work
in front by means of an arm or spindle, the position of which can be adjusted by

inserted and adjusted correctly, with great ease and exactness; because it is easily
accessible to the eye and hand of the operator, and the set screws easily within
reach.
The introduction of the thread is effected in the generally known manner, and
likewise is the position of the needles, the same as is usual in circular.knitting
machines.
The improvement is not only applicable to large or new apparatus, but may also
be applied to others which have been made on the old principle.

I WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, in the county of Lancaster, and of
323 High Holborn, in the county of Middlesex, Civil Engineer; do hereby declare
the nature of the said invention for "IMPROVEMENTS IN CIRCULAR KNITTING
MACHINES (a communication from abroad by Rafael Stahl, Stuttgart, Wurttem-
berg, Germany), and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
"
In the controlling or actuating mechanism for circular knitting machines the
mesh forming eccentric or device is applied in such a manner, that it exerts a down-
ward pressure on the backs of the guide discs of the plates, that is, on that side
of the plates facing inwards, or towards the articles being woven or knitted, as
indicated in the accompanying drawing, Fig. 1, by the dotted eccentric v; or a
third annular guide-disc is applied through which the arm of the eccentric passes,
so that the eccentric exerts a pressure on the plates between the guide-discs or on
the outer side of the plates. In these known arrangements therefore the eccentric
presses from above upon the plates, and indeed always on that portion of the same
which faces the needles, whereby the evil arises that a lateral strain is frequently
exerted upon the plates and thereby a bending of same is occasioned.
The object of this invention is to remedy this. evil, and at the same time to bo
able to superintend and control from outside, with ease and convenience, the proper
working of the plates between the needles. In the improved arrangement, shown
in Figs. 1 and 2, the eccentric or device which actuates these plates is adjusted so
that it no longer lies between or behind the guide-discs f and f¹ of the controlling
or actuating mechanism, but is placed or situated outside the guide-discs, and must
therefore, since the fulcrum of the lever-formed plates, p and p¹ is.at x, act on the
plates from below, by raising the heads of the same, so that there is imparted to the
other (hooked) ends of the plates a downward motion between the needles n with
great regularity and safety.
In order to bring about a correct dropping of the plates, there is here, as is the
case in all controlling or actuating mechanisms, situated a correspondingly formed
lever commonly termed a "Bügel" ie, flat iron, by the German manufacturers of
circular knitting machines. The eccentric a is connected to the front part of the
support of the controlling or actuating mechanism by means of the arm t, and is
adjusted by screws 8 and s¹. The eccentric can be regulated and correctly adjusted
with great ease and exactness, for it is easily accessible to the hand and eye of the
operator.
The introduction of the thread F is effected in the generally known manner, and
also the position of the needles n is the same as is usual in circular knitting
machines.
The improvement is not only applicable to large or new apparatus, but may also
be applied to others which have been made on the old principle.
Figs. 3 and 4 show a detailed drawing of the mesh forming eccentric or device a,
these Figs. differ from Figs. 1 and 2 in so far that the arm t in the latter Figs, was

page_text: screwed direct to the front part of the support of the controlling or actuating
mechanism, in the present. instance however it is held by the guide-piece w, and can
be adjusted in the latter and is fixed by the screw V. A second eccentric a¹, also
adjustable by means of screw b, is also fixed to the eccentric a; and by this the
eccentric can be adjusted more exactly and precisely than hitherto, and in case of
wear, which easily takes place at certain portions of the eccentric a, the use of the
eccentric a¹ will be found advantageous..
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
In large controlling or actuating mechanism, on the new principle, as well as in
small mechanism, on the old principle, for circular knitting machines, the arrange-
ment of the mesh forming eccentric or device a outside the guide-disc fand flin
such manner that the eccentric a shall act from below upon that portion of the
plates lying outside."
