Improvements in Self-acting Mules.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention and in what manner the
same is to be performed, as communicated to me by Albert Emil Heipt, of Forst,
Brandenburg (Lausitz), Germany, Machine Fitter, and Carl August Beyer, of
Crimitschau, Saxony, Machine Manufacturer, to be particularly described and ascer-
tained in and by the following statement :-
In self acting mules in which the wire of the winding-on apparatus moves up and
down in a perpendicular plane, and this movement is obtained by the undulated form
of the surface of a bar or rail which guides the roller of the trailing bar, as all upward
and downward undulations are at the same height, all winding layers, formed at one
and the same running in, are also of the same height and each two groups of layers,
resulting from two consecutive runnings in of the carriage, jeopardise the security of
the layers of the several or the individual lowest windings. For this reason, in the
present invention, the upward, and likewise the downward undulations, are arranged
in an oblique line, so that the several or individual layers of the windings of each
group are pushed sufficiently far against one another in the direction of the spindle-
axis, in order to ensure a secure placing or laying of each winding:
A self acting mule improved in this manner is explained below in connection with
the accompanying drawing, in which Figs. 1 to 7 represent the various positions of
the winding on apparatus, and the counterfall or counter-winder; Figs. 8 to 13
illustrating in a corresponding manner the production of the cop.
Fig. 14 also illustrates the formation of the cop.
The roller o¹, working in cooperation with the rail or bar p Figs. 1 to 7, acts by
means of the connecting rod and the arm i on the shaft a bearing the several
winders b, in the manner known. The rail on the bar p, however as mentioned, has
its zigzag running surface, which acts in combination with the roller o¹, so formed that
the downward undulation O, Fig. 7, is higher than the downward undulation II,
Fig. 5, the downward undulation II on the other hand being higher than the downward
undulation IV, Fig. 3, finally the downward undulation IV is higher than the
downward undulation VI, Fig.1. Likewise, the upward undulation I, Fig. 6, is higher
than the similar undulation III, Fig. 4, and the upward undulation III again is
higher than the similar undulation V, Fig. 2.
The thread, which is subject to the action of a counter-winder q in the known
manner, is wound on to the spindler for the purpose of forming a cop, in the following
manner, according to this invention a bar or rail p being employed.
"
If the roller o be moved from the position O, Fig. 7, to I, Fig. 6, the winding on
apparatus & executes the last part of the movement constituting the backing off,
going from the position in Fig. 7 to that in Fig. 6. Now begins the "winding on
of the first layer of thread Figs. 14 and 12. As this layer must be made upwards
from below, and the winding on apparatus b has to execute an upward movement,
and the arm i of the winding on shaft a a downward movement, on the rail or bar p
the roller of moves from the upward undulation I, Fig. 6, into the downward undu-
lation II, Fig. 5. The winding apparatus b, in other words, the wire b¹, thus moves

page_text: from the position in Fig. 6 into that shown in Fig. 5. In consequence of the roller o¹
running out of the downward undulation II on to the upward undulation III, a fresh
downward movement of the wire b¹ is induced. This movement ceases, as soon as
the wire b¹ reaches the position in Figs. 4 and 11. Owing to the passage of the
roller o from the position III into the position IV the second layer of thread is formed,
which partially covers that first formed and is illustrated in Figs. 3 and 10. Again,
in consequence of the passing of the rollers from the position IV to the position V,
a downward movement of the wire b' is effected as far as the position shown in
Figs. 2 and 9.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
A winding on apparatus for self acting mules for the production of cops wound in
alternate upward and downward spiral windings the distinguishing feature of which
is that the upward undulations (I, III, V) and the downward undulations (O, II, IV, VI)
are arranged in a line deviating from the horizontal, for the purpose of pushing
each of the layers of thread against the one previously formed, so far in the direction
of the spindle axis that these layers of thread secure a firm or certain hold sub-
stantially as described.
