1, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to ordinary selfacting spinning machinery, and it has for its
object a novel method of construction by which the spindles may be made to revolve
in either direction, as and when required.
The rotation of such spindles is ordinarily effected by means of driving pulleys or
drums fixed upon a solid revolving shaft driving the spindle drums, and through them
the spindles, in one direction only by means of endless cords. If therefore the
rotation of the spindles is to the right it can only be altered to the left by altering or
crossing the driving cords, by which much time is lost, and the cords are quickly
worn out.
By the present invention the direction of rotation can be altered without difficulty
whenever desired, and without altering the driving cords.
For this purpose the driving pulley and other usual gear are mounted upon a hollow
shaft, instead of upon a solid one as is usually the case, this hollow shaft fitting freely
upon a solid shaft inside it, and supported by suitable bearings. Motion can be
transmitted to the inner shaft by means of two bevelled toothed wheels facing each
other, one being fixed upon the hollow shaft and the other upon the solid shaft near
one end, and a third bevelled wheel being arranged between them upon a separate
shaft or axis so that the wheels can be connected or disconnected.
The ordinary spindle carriage and driving mechanism for the spindles are use.l.
The cord pulley and one of the bevelled toothed wheels are fixed upon the hollow
shaft, whilst the other opposite bevelled wheel and the spindle drums are fixed upon
the inner solid shaft. Moveable couplings are also arranged by which the outer
hollow and inner solid shafts can be coupled together and disconnected.

page_text: If therefore the two shafts are coupled together, and the intermediate bevelled
wheel is at the same time thrown out of gear with the other wheel, the driving cord
pulley upon the outer hollow shaft will drive the spindle drums upon the ends of the
inner solid shaft in the same direction. If, however, the two shafts be disconnected,
and the three bevelled wheels thrown into gear together, the driving cord pulley will
continuo to turn the outer hollow shaft in the same direction but that of the inner
shaft and spindle drums, and consequently of the spindles driven from the latter, will
be reversed.
The coupling and uncoupling of the shafts and wheels may be easily effected by
handles and sliding clutches in the usual well known way.
Instead of bevelled toothed wheels, their equivalents such as spur wheels or pullies
and cords suitably arranged may be used for the purpose of altering the direction of
rotation of the outer and inner shafts.

Improvements in Selfacting Spinning Machines.
A communication to me from abroad by ROBERT SCHNEIDER, of Biala, in the Empire
of Austria, Manufacturer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex,
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 and accompanying drawing (that is to say) :-
:-
This invention relates to ordinary self-acting spinning machinery, and it has for its
object a novel method of construction by which the spindles may be made to revolve
in either direction, as and when required, without any alteration of the driving bands
or cords.
The rotation of such spindles is ordinarily effected by means of driving pulleys or
drums fixed upon a solid revolving shaft driving the spindle drums, and through them
the spindles in one direction only by means of endless cords.
If therefore the rotation of the spindles is to the right it can only be altered to the
left by altering or crossing the driving cords, by which much time is lost and the
cords are quickly worn out.
By the present invention the direction of rotation can be altered without difficulty
whenever desired, and without altering the driving cords.
The accompanying drawing is in illustration of the invention, figure 1 being a plan
of the middle part of a spindle carriage and the driving mechanism for the spindles.
Figure 2 is a section shewing the solid shaft a and the hollow shaft b revolving in
the same direction, and figure 3 shews the two shafts revolving in opposito directions.
The driving pulley i and other usual gear are mounted upon a hollow shaft b, instead
of upon a solid one as is usually the case, this hollow shaft fitting freely upon a solid
shaft a inside it, and supported by suitable bearings. Motion can be transmitted to
the inner shaft a by means of two bevelled toothed wheels G and E facing each other,
one being fixed upon the hollow shaft and the other upon the solid shaft near one end,
and a third bevelled wheel F being arranged between them upon a separate shaft
or axis so that the wheels can be connected or disconnected.
The ordinary spindle carriage and driving mechanisin for the spindles are used.
The cord pulley i and one of the bevelled toothed wheels G are fixed upon the
hollow shaft b, whilst the other opposite bevelled wheel E and the spindle drums CC,
are driven by the inner solid shaft a. Moveable couplings B and D being arranged by
which the outer hollow and inner solid shafts b and a can be coupled together and dis-
connected as required.
If therefore the two shafts a and bare coupled together, and the intermediate
bevelled wheel F is at the same time thrown out of gear with the other wheels, the

page_text: driving cord pulley upon the outer hollow shaft will drive the spindle drums upon
the ends of the inner solid shaft in the same direction. If, however, the couplings
at B and D are disconnected, and the three bevelled wheels E, F, G, thrown into gear
together, the driving cord pulley will continue to turn the outer hollow shaft & in the
same direction, but that of the inner shaft a and spindle drums, and consequently of
the spindles driven from the latter, will be reversed.
The coupling and uncoupling of the shafts and wheels may be easily effected by
handles and sliding clutches in the usual well known way.
Instead of bevelled toothed wheels, their equivalents such as spur wheels or pullies
and cords suitably arranged may be used for the purpose of altering the direction of
rotation of the outer and inner shafts.
The paris marked F, H, and h relate to the ordinary apparatus for running in and
out the carriage and the winding of the cop and are not referred to in the present
invention.
Having now particularly described and ascertained the nature of the said inven-
tion and the manner in which the same is to be performed, I declare that what I
claim is :-
In the spindle carriage of self-acting spinning machines, the combination of the
hollow shaft b, the solid shaft a, and the bevelled toothed wheels E, F, G, or their
equivalents, and couplings at B and D, substantially as described and shown.
