COMPLETE SPECIFICATION.
Improved Needle Rail for "Cotton" Knitting Frames.
I, FRIEDRICH ANTON LUDWIG, Manufacturer of 16 Wilhelm Strasse,
Chemnitz, Germany do hereby declare the nature of my invention and the
manner of performing the same to be particularly described and ascertained in and
by the following statement :-
My invention relates to a needle rail for Cotton's knitting frames and its object
is to prevent the bending and damaging of the needles which so often happens in
making the course in the frames hitherto in use.
It is well known that the needles in Cotton's knitting frames are considerably
longer than those of any other frames and besides this are generally flat so that the
slightest influences such as knots or impurities in the yarn, are sufficient to bend
the needles sidewardly (in the direction of the section) thus breaking off the points
of the same or bending them, tearing holes in the ware or damaging the
sinkers etc. etc.
The main advantage of my improved needle rail, is that the same, in either of
the above mentioned emergencies does not require to be taken out or removed from
the frame, but is simply turned upwards without causing any further inconvenience.
On removing the needle rail in order to adjust the needles, for instance, there is
generally no room to put it down after it has been unscrewed or unhinged. My
improved needle rail further enables the employment of much inferior yarn than
heretofore. The quality of the goods manufactured is also improved, by the
employment of my improved needle rail, as the needles cannot give, or bend, in
making the course and the retirement of the sinkers is prevented.
In order to make this Specification more easily intelligible I refer to the
accompanying drawings in which similar letters denote similar parts throughout the
several views:-
Fig. 1 is a partial sectional elevation of my improved device.
Fig. 2 is a front elevation of the same.
Fig. 3 shows a detail view of the needles.
Fig. 4 shows needles which have been bent and
Fig. 5 is a detailed partial plan of a recessed needle rail.
Spindles e are arranged in brackets g near the narrowing bar f each bracket
being arranged to support two spindles as may be seen in Fig. 2. The needle rail a
which is beveled off at the side coming in contact with the needles, is carried by
the arms & mounted on the spindles e and serving as collars for holding the same in
position being secured by means of set screws.
The arms are provided with weights ce cast onto the same and which have the
tendency to hold the needle rail a with a certain amount of pressure against the
needles m.
Pressure springs may be substituted for the weights c if found desirable. In
narrowing it is necessary to remove the needle rail from the needles, this is
accomplished in the following manner :-
When the narrowing bar, which is pivoted at h, is lowered, the shaft of the
same slides along the curve d of the arm b pushing back the rail a from the needles m.
On raising the narrowing bar again, the rail a falls back onto the needles under
influence of the weights c or their equivalents.
The rail a may also be provided with recesses for the reception of the needles as
shown in Fig. 5.
If it is desired to remove the rail a right away from the needles, the same may
be turned upwards, until the rest on the upper part of the arm 6 comes to lie on
the nose i of bracket a

page_text: Having now particularly described and ascertained the nature of my said inven-
tion what I claim as my invention is :-
1) A cotton knitting frame, having a self acting, swinging needle rail pressed
against the needles by means of a weight such as c or pressure spring, and which
may be turned back and upwards, away from the needles substantially as described
and shown.
2) The combination of the brackets g having mounted therein, spindles e
carrying arms b having curved interior sides d and weight c and supporting needle
rail a, said rail being adapted to be raised from the needles by means of shaft fof
the narrowing bar substantially as described.
3) In combination with the arms & having weight and curved surface d, the
rest arranged to close onto nose or projection i of the brackets g substantially as
described and shown.
