Improvements in or relating to Spinning and Twisting Machines.
We, ANTOINE CLAD, Manufacturer, of Charlottenburg, in the Empire of
Germany, and EMIL SCHNABEL, Engineer, of Altona-Bahrenfeld, in the Empire
of Germany, 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:-
-
The present invention relates to improvements in spinning and twisting machines
for the purpose of
1) avoiding the accumulation of dust underneath the front cylinder and the
consequent contamination of the thread by the dust, and
2) avoiding the formation of double threads knots or other disorders consequent
on the breakage of a thread often causing the breaking of a thread by its end
becoming caught in the adjacent thread.
The invention is illustrated in the accompanying drawing, in which
Figure 1 represents a transverse section of part of a machine to which the
invention has been applied,
Figure 2 being a plan view of same.
The thread guides a are not fixed on the frame b, but are supported in corre-
sponding grooves in a shaft c driving the brush roller or clearer d, their rear ends
resting against a ledge f situated behind the driving shaft c whilst the thread
is being drawn off whereby they are secured against falling.
The roller d which is covered with felt or plush or any other material suitable
for the purpose, is driven frictionally by the shaft c, receiving thereby a rotation
in the opposite direction, as shown by the arrows in Figure 1.
Above the roller d is the roller g of the drawing rollers g h.
The roller d takes up or removes the dust from the driving shaft and also
catches the dust which falls from the drawing roller g and carries it to the rear
away from the thread e. In consequence of this, backward rotation of the brush
roller whenever a thread breaks the broken end is caught by, and entwined on,
the said brush roller, thus keeping it out of reach of the neighbouring threads,
whereby the formation of double threads is avoided, see Figure 1.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A device in spinning and twisting machines, for preventing the formation
of double threads, knots or other disorders consequent on the breakage of
threads, consisting in an arrangement whereby the thread guides are not fixed
but are supported in guide grooves on a shaft which drives a brush, roller or
clearer, the rear ends of said threads guides resting against a ledge as f and
secured against falling; the brush roller in consequence of being driven by the
thread guide shaft rotating in the opposite direction, whereby any loose thread

page_text: following a breaking of a thread, is immediately caught by and wound upon said
roller substantially as described.
2. The complete means for preventing the formation of double threads, knots
and the like substantially as described or illustrated in the accompanying draw-
ings.
