We CARL AUGUST ROSCHER and FRANZ KNORR both of Mittweida near Chemnitz
Saxony Manufacturers do hereby declare this invention to be as follows:-
This invention consists of a looper for circular hosiery web machines having any
convenient number of guide plates for the jacks in which the action of the sinker
upon the jacks takes place within these discs and also inside the cam plate instead of
outside.
An objection in hosiery web machines as heretofore constructed with long jacks is,
that in working the jacks sometimes strike the needles instead of striking in the
spaces between the needles. To obviate this the following looper or stitch forming
arrangement has been devised.
The jacks are guided in the usual radial slots of two or more discs. One of these
discs or guide plates is placed so far towards the interior of the machine that it is at a
little distance only from the needle heads.
The circular aperture of the disc which gives an annular shape to the said disc
allows an arm to reach into the stitch forming arrangement and on this the sinker is
secured. This will consequently depress the jacks between the guides whereas hereto-
fore this was done in front of the guide plates close to the needles.
As now the pressure of the sinker is exerted upon the jacks within the guides the
jacks are no longer pushed out of position laterally and descend with certainty
between the needles, the more so as they are guided immediately in front of them.
As moreover the sinker does not press upon the front of the jacks but more
towards the centre or even further inward, its downstroke need not be so great for
considerably depressing the lever like jacks and as the sinker no longer requires to
have so sharp an angle it will not push the jacks aside.
With the same height of sinker a much longer loop or stitch can now be made than
formerly.
The fall of the jacks is limited by a guard which together with the sinker is adjusted
in accordance with the required length of stitch. As the sinker is no longer
suspended in front of the needles the stitch forming arrangement can be brought
nearer to the needle heads than heretofore and more room is thus gained for fixing a
press wheel.

Saxony Manufacturers do hereby declare our said invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention consist of a looper for circular hosiery web machines having any
convenient number of guide plates for the jacks in which the action of the sinker upon
the jacks takes place within these discs and also inside the cam plate instead of
outside.
An objection in hosiery web machines as heretofore constructed with long jacks is,
that in working the jacks sometimes strike the needles instead of striking in the
spaces between the needles. To obviate this the following looper or stitch forming
arrangement has been devised.
Figure 1 of the accompanying drawings is a sectional side elevation and figure 2 a
part sectional part end view of a looper having two plates a and a². The jacks band b
are guided in the usual radial slots of the discs a and a¹. The disc or guide plate a¹
is placed so far towards the interior of the machine that it is at a little distance only
from the needle heads. The circular aperture f in the disc a' which gives an annular
shape to the said disc, allows an arm e to reach into the stitch-forming arrangement
and on this arm e, the sinker g is secured. This will consequently depress the jacks
between the guides a and a¹ whereas heretofore this was done in front of the guide
plate a¹ close to the needles c. As now the pressure of the sinker g is exerted upon
the jacks within or between the guides the jacks are no longer pushed out of position
laterally and descend with certainty between the needles the more so as they are
guided immediately in front of them.
As morcover the sinker g does not press upon the front of the jacks but more
towards the centre or even further inward, its down stroke need not be so great for
considerably depressing the lever like jacks and as the sinker g no longer requires to
have so sharp an angle it will not push the jacks aside. With the same height of
sinker a much longer loop or stitch can now be made than formerly. The fall of the
jacks is limited by a guard which together with the sinker is adjusted in accordance
with the required length of stitch. As the sinker is no longer suspended in front of
the needles the stitch forming arrangement can be brought nearer to the needle heads
than heretofore and more room is thus gained for fixing a press wheel.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
The improved looper for circular hosiery web machines in which the jacks are so
guided in two guide discs that the effect of the sinker g on the jacks takes place
within or between the guides of the latter and substantially as shown on the drawings.
