COMPLETE SPECIFICATION,
Improvements in Apparatus for Driving the Spindles of Self-acting
Mules.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
ex, 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 particu-
larly described and ascertained in and by the following statement:-
This invention relates to apparatus for winding the spindles of self-acting mules
of the kind having a zigzag bar or rail, the object of the invention being to
automatically reduce, or increase, the rotary speed of the spindle, as necessary with
reference to the zigzag bar or rail. This rotary speed must be greater in the case
of a small winding on diameter being in question, and less in the case of such
diameter being larger. The alteration between the maximum and the minimum
speed is chiefly effected, according to the present invention, by means of eccentric
wheel gearing, the transition being brought about gradually, and, as a matter of
fact in, such a manner that a pair of eccentric wheels are employed, which make
as many rotations as there are upward and downward movements of the roller
attached to the trailing bar acting in combination with the zigzag bar or rail,
at each running in of the carriage.
The invention is illustrated in the accompanying drawing which is a general
view in elevation.
In the form given by way of example the zigzag rail or bar has three upward
undulations I, III, V, and four downward undulations O, II, IV, VI, Fig. 1, so
that there are three upward and downward movements of the roller o¹, which acts
in combination with the zigzag bar or rail, at each running in of the carriage.
Accordingly, the rotary speed of the spindler must be three times at the minimum,
and three times at the maximum, during each run in of the carriage, that is,
each wheel of the pair of eccentrics, w, must rotate three times during each
running in. Consequently, the spur wheel s, which together with the eccentric. v,
is keyed to the shaft u, and acts in combination with the fixed rack or tooth
rod t, must run along the rack and rotate three times during each run in of the
carriage. In the form given as an example moreover, a spur tooth wheel gear-
ing 2, 3, 5, S, is inserted between the eccentric gearing and the shaft h of the
cylinder 6, the endless band 7. of which passes around the sheave 8 of the spindler.
In connection therewith, the spur-wheel 2 is keyed to the shaft 1. of the eccentric
wheel w; the spur-wheels 3, 5, are keyed to a shaft 4, and the spur-wheel S to
the shaft h of the cylinder. The object of this intermediate spur wheel gearing is
to transmit the alternating speed of the eccentrics to the driving cylinder.
During the outward run of the carriage the winding-on mechanism is put out of
action in the same manner as heretofore in connection with this class of mechanism.
The trailing bar n acts, in the manner known, by means of the connecting rod k,

page_text: and the lever i on the winding shaft a, upon the winding on apparatus 6 belonging
to the latter.
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 :
A spindle driving apparatus for self acting mules for the production of cops
wound in alternate upward and downward spiral windings, by means of a zigzag
bar or rail, the distinguishing feature being that the spindles have a velocity
imparted to them corresponding to the diameter of these spiral windings at the
time substantially as described.
