COMPLETE SPECIFICATION.
A New or Improved Doubling and Winding Machine.
I, LEO SCHILDKNECHT, of 14 Schützenstrasse, Meerane, in the Kingdom of Saxony,
Foreman Spinner, 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 a particularly simple doubling machine which is also
capable of being used as a winding machine, and which has the advantage of
possessing a considerably greater output-capacity as compared with the machines
heretofore known. The new machine is illustrated in the accompanying drawings
in which -
Figure 1 is a side elevation,
And Figure 2 is a section on the line A-B of Figure 1.
The bobbin spindle b upon which the sleeve c is mounted, is operated from any
suitable driving gear a (which may consist either of a hand wheel or of an electric
motor) by means of suitable gearing, for example by means of cord driving gear,
The bobbin spindle b is enclosed by a bearing d and is supported in an overhung
manner by a foot e which is mounted on a bar or fillet f. The latter is rendered
adjustable in a vertical direction by means of two bearings g and h, and it bears upon
the bobbin plate i which is mounted so as to be capable of lateral movement in the
slide k. For the purpose of producing this lateral movement of the bobbin plate, the
latter carries a nut in which works a spindle m. A ratchet wheel n mounted upon
the spindle is operated by means of a pawl o.
One end of a cord x is attached to the
pawl o and after passing over a guide pulley carried by the frame, the free end is
made fast to the end of a crank p which is fixed on the shaft of the driving
gear a.
The uniform rotation of the driving gear produces by this means an intermittent
rotation of the ratchet wheel n, and consequently an intermittent lateral motion of
the bobbin plate i. This plate i thereby allows the bobbin spindle 6 to fall uniformly,
and it thus produces in the usual manner the desired peculiar shape of the cop.
This is
For this purpose the thread guide q is caused to oscillate up and down.
effected by causing the said guide to bear by means of a pin r upon a lever 8, which
is guided or carried by the fillet t and oscillates about a fixed point u, and is recipro-
cated by means of a cam v which is rotated in any suitable manner from the
driving gear a. In the arrangement shown in the accompanying drawing, this
rotation is effected by means of a driving cord.
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) A doubling and winding machine in which the vertical bobbin spindle bears
upon a bobbin plate i that slides at right angles to the axis of the spindle, whereby
the spindle is moved in a vertical direction, whilst at the same time a thread guide
oscillates to and fro in one and the same plane with the axis of the bobbin.
