PROVISIONAL SPECIFICATION.
Improvements in Circular Knitting Machines.
We, FRANZ BLUMENSTEIN, of 226, Upland Road, East Dulwich, S.E., Manu-
facturer, and FRANCIS THOMAS PINSON, of 16, St. Mark's Road, in the Parish of
Lambeth, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to circular knitting machines and is a further and
decided improvement in the adjustment of the dial needles to existing machines.
Although we are well aware that certain adjustments are made by the needle
cylinder in existence and by an adjustable post, which we find is not always or
quite suitable and is difficult for the operator.
But by this our invention and improvements which are particularly in the
adjustment of the dial needles which we effect in the following manner, riz.:—
We adopt the rib spindle, dial and cam plate also the concave and convex
rollers.
To make the dial adjustable the spindle which carries the dial and cam-plate
is bored vertically in its length-to a suitable diameter as to take or receive an
inner spindle or rod which is connected to a clutch of conical form or of other
shape or form to ensure the required gripping action of the under part of the
dial or needle disc.
On the top of the rib arm spindle we form a suitable counter-bore to receive a
suitably shaped nut for the securing and releasing of the needle dial; the inner
spindle has a thread formed thereon to work into the suitably shaped nut
referred to, which nut is reduced to fit the chambered part in the top of the
spindle which has the vertically bored hole through and the said nut we can
or may secure in position by means of either a flange, screws or other mechanical
means. When the nut is tightened the dial is made rigid but when released the
operator can easily adjust the needles to suit the work in hand.
A projection is formed in connection with or part of the conical or like form
of clutch which would be slotted out in a horizontal direction to receive a roller
to work freely therein. This roller we make adjustable so as to permit of the
different sizes of fabric that may be in use and when knitted to pass freely
through both this the concave and that of the convex roller, as provided, the
said convex roller we secure to a stationary post fitted to the base of the machine
or in other suitable manner.
Dated this 5th day of November 1898.

We, FRANZ BLUMENSTEIN, of 226, Upland Road, East Dulwich, S.E., Manu-
facturer. and FRANCIS THOMAS PINSON, of 16. St. Mark's Road, in the Parish of
Lambeth. Mechanical Engineer, 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:-
This invention relates to circular knitting machines, and more especially to
the adjustment of the needle dial.
And in order that our said invention may be better understood, we will now
proceed to describe the same with reference to the drawings accompanying this
specification, in which Fig. 1 shows sectional elevation of needle cylinder and
dial Figs. 2 to 5 show details hereinafter referred to.
The same letters of reference are employed to denote the same parts in all the
views.
a shows the spindle which carries the needle dial and camplate c. This
spindle a (which is shown detached in elevation at Fig. 2) is made hollow to
receive an inner spindle d which is connected to a tapered clutch e to ensure
the required gripping of the under part of the dial b. This clutch e is of such a
form as to engage and be rigidly connected to the under part of the said dial b.
The inner spindle is shown detached in elevation at Fig. 3. and in plan at
Fig. 4. f shows a nut fitting in the hollowed top g of the spindle a and screwing
on the threaded portion of the inner spindle d. This nut f is free to turn in
the portion of the hollow spindle a, but is prevented from moving vertically
by the screws or pins which engage in a groove in the said nut.
shows a projection extending from the clutch e, of sufficient length to engage
with the post on the needle cylinder . We prefer to cast this post ; in one
with the said cylinder k. In the event of adapting this invention to existing
machines, the post i would be screwed or otherwise fixed to the cylinder.
The spindle a is carried by an arm m, terminating in a fork n, fitting over a
screw and held by a butterfly nut p. A front elevation of this arm m is shown
at Fig. 5.
In Fig. 1, s shows a cap fitting on a squared portion at the top of the inner
spindle d.
In order to adjust the dial b, the nut f is turned. The projection i being in
contact with the post 1, the inner spindle d does not turn. This spindle d there-
fore travels downwards (the nut ƒ being turned in the direction to give that
effect) and the clutch e is released. Then the dial 6 can be adjusted by turning
the spindle a round, a handle q being provided for this purpose: and the dial b
being so attached to the lower end of the spindle a (say by means of a squared
face on the spindle or by a key) that the spindle a and dial b turn together.
When the dial is adjusted as required, the nut f is turned in the opposite
direction in order to re-engage the clutch e. In performing this operation, the
inner spindle is kept from turning (if necessary) by the operator holding the
top cap s.
Instead of securing and releasing the inner spindle by means of a nut f, it
may be so secured and released by other suitable means.
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:-
1. Circular knitting machines constructed substantially as set forth.

the purpose set forth.
3. In circular knitting machines, making the needle dial adjustable.
