I, PAUL HEBBELYNCK, of Gand, in the Kingdom of Belgium, Spinner do hereby
declare the nature of this invention to be as follows:-
This invention relates to twisting mills or machines and has for its object to obviate
In certain cases the
any waste of thread owing to the breakage of the same.
improvements enable machines for winding or joining to be dispensed with.
In the following description I will consider a continuous twisting machine having
rings, but it is to be understood that the invention can be applied to other similar
machines.
The general arrangements of the machine are the same as those heretofore employed;
the present improvements relate only to the thread guides, the cap bars and the top
rollers, and in certain cases to the lower rollers, it will therefore be unnecessary to
describe other parts.
The thread guide consists of very simple mechanism which renders unnecessary the
employment of special means for automatically stopping the machine in case a thread
breaks.
In the improved machine two or three ends can be united simultaneously with the
twisting, and upon the same machine.
The improved thread guide is composed of two glass hooks, which, instead of
being fixed, are adjustable and maintained in position by set screws in a support
which is movable upon a pivot. The hooks upon a single support operate in the
following manner.
As long as the thread does not break in passing from the bobbins it presses one
book in a direction which would cause the thread to pass by the side of the top roller
if, after having passed over this top roller it did not press the other guide in the
opposite direction so as to hold the guide in equilibrium, to guide the thread to the
middle of the top roller.
The thread after having passed through the second hook and over a grooved glass
rod, is wound upon a bobbin, giving to the thread a certain tension.

page_text: If the thread breaks, between the top roller and the hobbin, the tension upon the
second hook guide ceases, and the thread moves the first hook guide in such a manner
that the former falls by the side of the top roller upon a hook of the cap bar. The
thread can fall only upon the hook of the cap bar, because the latter is placed in a
recess in the top roller.
If the thread is carried away by the lower roller, it is guided by one of the sides of
the cap bar hook so as to be taken by teeth on the top roller. The latter, turning in
the reverse direction, draw the thread by means of its teeth and thus entirely obviates
the production of waste.
The journal of the top roller which is on the side of the cap bar hook is pointed in
order that the thread cannot be wound upon it. The thread coming from the bobbins
passes through the first guide hook and the top roller, and back between the latter
and the lower roller, it then traverses the second guide hook and proceeds to the
bobbins after having passed over the glass rod.

page_text: In the following description I will consider a continuous twisting machine having
rings, but it is to be understood that the invention can be applied to other similar
machines.
The general arrangements of the machine are the same as those of machines
heretofore employed; the present improvements relate only to the thread guides,
the cap-bars and the top rollers; it will therefore be unnecessary to describe other
parts.
The thread guide consists of very simple mechanism which renders unnecessary the
employment of special means for automatically stopping the machine in case a thread
breaks. In the improved machine two or three ends can be united simultaneously
with the twisting, and upon the same machine.
The improvements in the top roller M consists in forming a groove in one of the
sides; this grooved part allows room for a hook on the cap bar; this hook prevents
the thread, when it falls from the top roller, from being drawn away by the bottom
roller. The said roller is also formed with notches or teeth for picking up the thread
that falls upon the hook of the cap bar as hereinafter described.
The improved thread guide is composed of two glass hooks, I, R, which, instead of
being fixed, are adjustable and maintained in position by set screws in a support
which is movable on a pivot U, fixed upon a transverse bar. The hooks L. R upon a
single support operate in the following manner.
As long as the thread K does not break in passing from the bobbins, it presses the
guide L in a direction which would cause the thread K to pass by the side of the top
roller M if, after having passed over this top roller it did not press the other guide R
of the hinge in the opposite direction so as to hold the support S in equilibrium, to
guide the thread K to the middle of the top roller M.
The thread K, after having passed through the guide R and over a grooved glass
rod V, is taken by the runner and wound upon a bobbin, giving to the thread a
certain tension.

page_text: If the thread breaks, between the top roller M and the bobbin, the tension upon the
guide K ceases, and the thread K moves the guide L in such a manner that the
former falls by the side of the top roller M upon a hook O of the cap bar N. The
thread K can fall only upon the hook O of the cap bar because, the latter is placed in
a recess in the top roller M.
If the thread is carried away by the lower roller, it is guided by one of the sides of
the cap bar hook O so as to be taken by teeth P on the top roller M and the latter,
turning in the inverse direction, draws the thread by means of its teeth P and thus
entirely obviates the production of waste.
The journal of the top roller M which is on the side of the cap bar hook O, is
pointed in order that the thread K cannot be wound upon it. In the drawings the
motion of the thread is indicated by arrows. The thread coming from the bobbins
passes through the guide .L over the top roller and back between the latter and the
lower roller, it then traverses the guide it and proceeds to the bobbins after having
passed over the glass rod V.
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 :-
First. In twisting machines, the simultaneous combination of a hinged thread guide,
of a top roller or pulley with or without a groove, and of a bottom roller, as and for
the purpose specified.
Second. In twisting machines, the cap bar having a book, substantially as described
and represented in the drawing for the purposes specified.
Third. In twisting machines the hollow top roller in combination with a point
shaped journal, and the hooks for drawing the thread, substantially as represented and
described.
Fourth. In twisting machines the employment of a double thread guide upon a
single hinge, and regulated by the tension of the thread, as and for the purpose
specified.
