1, GUSTAV JOSEPHY of Bielitz, Empire of Austria, manufacturer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to selfacting mules, or selfactors, provided with driving-gear
whereby during each run of the carriage the spindles are caused to rotate at different
speeds in succession, and its object is to produce three different speeds by means
being more simple and advantageous than those heretofore employed.
For this purpose I combine, with the ordinary gear adapted to operate the
spindles at two different speeds, certain additional parts, which I shall describe with
reference to the annexed drawing.
In this drawing a is the line of shafting from which the machine is driven. D is
the shaft of the overhead gear, and
the shaft of the head stock of the selfactor.
On the shaft K are fixed the pulley m and the twist-wheel n, while to a sleeve B,
rotating on the shaft K, are secured the pulley p and the twist-wheel q, the latter
being of larger diameter than the wheel n. To the shaft D are keyed the two
pulleys d and i, and to the shafting a the pulley b. o and e are loose pulleys. k is the
strap by which motion is conveyed from the pulley b to the pulley d, and u a strap
which connects the pulley i with either of the two pulleys m and p. Considering
that the twist-wheels n and q are both in connection with the drum from which the
spindles are driven, it is evident that two different speeds will be imparted to the
latter according as the strap u runs on the pulley p or on the pulley m.
Now, in order to attain a third speed, the overhead gear is fitted with the loose
pulleys 9 and f being smaller in diameter than the pulley d, and the pulley h keyed
upon an extension of the boss of the pulley g, and of like diameter as the pulley i.
Moreover, the line of shafting a is provided with the pulley & having the same size
as the pulley b and arranged to drive the pulley 9 by means of the strap I, and the

page_text: pulley p is made wide enough as that, according to the position of the strap u, the
said pulley will be driven either from the pulley h or the pulley i. If under these
conditions both straps k and are running on the respective pulleys d and 9, the
pulley will run faster than the pulley, and consequently, when the strap u is
shifted into the position u³, the pulley p and the twist-wheel will rotate faster than
if the strap is in the position shown in full lines, a third speed being thus attained.
The means for shifting the strap u into the position u³ are similar to those employed
for shifting it from the pulley p to the pulley m.

I, GUSTAV JOSEPHY, of Bielitz, Empire of Austria, Manufacturer, 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:—
My invention relates to self acting mules, or self actors, provided with driving-gear
whereby during each run of the carriage the spindles are caused to rotate at different
speeds in succession, and its object is to produce three different speeds by means
being more simple and advantageous than those heretofore employed.
For this purpose I combine, with the ordinary gear adapted to operate the spindles
at two different speeds, certain additional parts, which I shall describe with reference
to the annexed drawing, Fig. 1 whereof is a horizontal sectional view of the driving
pulleys, Fig. 2 a side-view of the selfactor-frame with strap-shifting mechanism, and
Fig. 3. an end-view corresponding to Fig. 2. Fig. 4 is an end-view showing the
movable parts in different positions.
In Fig. 1, a is the line of shafting from which the machine is driven. D is the
shaft of the overhead gear, and K the shaft of the headstock of the selfactor. On the
shaft K are fixed the pulley m and the twist-wheel n, while to a sleeve B, rotating on
the shaft K, are secured the pulley p and the twist-wheel q, the latter being of
larger diameter than the wheel n. To the shaft D are keyed the two pulleys d and i,
and to the shafting a the pulley b. and e are loose pulleys. k is the strap by which
motion is conveyed from the pulley b to the pulley à, and u a strap which connects
the pulley with either of the two pulleys m and p. Considering that the twist-
wheels n and q are both in connection with the drum from which the spindles are
driven, it is evident that two different speeds will be imparted to the latter according
as the strap u runs on the pulley p or on the pulley m.
Now, in order to obtain a third speed, the overhead gear is fitted with the loose
pulleys g and f, being smaller in diameter than the pulley d and with the pulley h,
keyed upon an extension of the boss of the pulley g and of like diameter as the
pulley. Moreover, the line of shafting a is provided with the pulley c having the
same size as the pulley 6 and arranged to drive the pulley 9 by means of the strap 1,
while the pulley p is made of such width that, according to the position of the
strap u, the said pulley will be driven either from the pulley h or from the pulley i.
If under these conditions both straps k and are running on the respective pulleys &
and 9, the pulley will run faster than the pulley i, and consequently, when the
strap u is in the position u³, the pulley p and the twist-wheel q will rotate faster than
if it is in the position u', a third speed being thus obtained.
The mechanism for automatically shifting the strap u comprises the strap-shifter
forming with the weighted arm & an elbow-lever, pivoted at and having the pin;
the palls a b', having the respective offsets 1, 2, co-operating with the pin ; the
rotating disk z with pin ¹, operating to disengage the said palls from the pin; the

page_text: levers, pivoted at s and having the cam-plate t; the bar s¹ connecting the outer end
of the levers with the arm ; the lever v, centered at w and having a cam-plate y,
the said lever being linked to the lever s at v¹, and the tappet r pivoted at to the
carriage A and bearing with an arm against the stop, so that the said cam-plates,
with which the tappet co-operates, are acted upon by the same during the run-out of
the carriage only.
During the first portion of the run-out of the carriage the strap u is in the position
shown by Fig. 1 in full lines, and by Fig. 3. When the tappet r meets the
cam-plate t, it depresses, by means of the same, the inner end of the lever 8, thereby
pushing the bar and arm upward and throwing the strap-shifter j into the
position in which it is represented by Fig. 4, the strap u then running on the
pulleys p and i. The pall a¹, resting unto this moment with its weighted arm a³ on
the pin, then drops with its offset 1 behind the pin, as shown by Fig. 4 and prevents
the strap-shifter from being drawn backward by the weight on the arm after
the tappet has passed the cam-plate t.
When, during the further motion of the carriage, the tappet r acts on the cam-
plate y, it produces a depression of the lover v, which is transmitted to the lever s,
and oscillates the same by a greater angle than it was oscillated in the first case, the
parts being suitably arranged for this purpose. The strap-shifter is thereby caused to
be thrown into its extreme position to the right (relatively to Fig. 4) so that the strap
will then be in the position u, in which it conveys motion from the pulley h to the
pulley p. At the same time the pall 61 engages by its offset 2 with the pin j³ and
locks the strap-shifter in the said position.
When the speed of the spindles is to be reduced again, the rotating pin z¹, acting
against the upright arms of the palls a' b' disengages the said palls from the pin,
whereupon the weight on the arm & returns the strap-shifter and the strap to the
position Fig. 3. During the run-in of the carriage the tappet r is free to turn on its
axle and therefore does not act on the cam-plates t and y.
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 :
In selfactors, the combination, with the over-head pulley i, head-stock-pulley m,
strap u, and gear for automatically shifting the strap u, of the pulley h having the
same diameter as the pulley i and driven at a greater speed than the latter, the head-
stock-pulley p having double the width of the strap u, and means for automatically
shifting the said strap u from the position u¹, in which it connects the pulleys
and p, to the position u³, in which its drives the pulley p from the pulley h,
substantially as and for the purpose described.
