Improvements in the Method of and Apparatus for Spinning and
Twisting Fibres.
We JOSIAH PORRITT, Laurel Street, Bradford, Scribbling Overlooker,
ALBERT PORRITT, Meadow Lane, Leeds, Lincensed Broker, MARSHALL
PORRITT, Leeds Road Bradford, Machine Maker, and WILLIAM HENRY
FENTON, Field Lane, Batley Shoddy Manufacturer all in the County of York,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to further improvements on Patent No. 136498.
The object of our invention is by a different arrangement of driving the drawing
rollers, and the revolving bearing boss for twisting, the driving is simplyfied, there
is less wear and tear of the parts, and less noise.
We employ a cross geared wheel, secured on each revolving twisting box or
bearing and on the drawing rollers we employ a peculiar shaped cross geared
bevel wheel which engages with a worm formed upon the inside periphery of a
loose boss upon the bearing boss, so dispensing with the bevel wheel and pinion
before employed for driving the drawing rollers.
We also employ a series of cross geared wheels upon both the back main driving
shaft and the front horizontal driving shaft to gear with the cross geared wheels
upon the revolving bearing and the drawing rollers, so dispensing with the chain
driving mechanism, or spur wheel gearing before employed.
For keeping the drawing rollers in gear we employ a buffer or bearing arranged
in a slot of the bearing of the drawing rollers. with a spiral spring placed so as
to act directly upon the axis of such drawing roller.
The front horizontal shaft is driven by change pinions from the main driving
shaft, so that it can be reversed or speeded as required to suit the various kinds
of yarns.

We, JOSIAH PORRITT Laurel Street. Bradford Scribbling Overlooker,
ALBERT PORRITT, of Meadow Lane, Leeds, Licensed Broker, MARSHALL
PORRITT, of Leeds Road, Bradford, Machine Maker, and WILLIAM HENRY
FENTON, of Field Lane, Batley. Shoddy and Mungo 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:
The object of our invention is to draw and spin fibres at one operation and so
dispense with mule spinning machinery usually employed for such purposes.
We employ rollers upon rotary bearings mounted upon a suitable frame between
each spindle and its feed rollers, so as to effectually draw the fibres and impart
the required twist or twine to such fibres as they are drawn between the said
rollers.
The said rollers as they revolve and draw the fibres through. have imparted to

operation.
DESCRIPTION OF DRAWINGS.
Fig. 1. is an end elevation in section showing spinning frame with our invention
applied.
Fig. 2. is a plan of part of spinning frame showing the driving of same.
Fig. 3. is a full sized elevation in section of the boss or bearing..
Fig. 4. is a plan of underside of Fig. 3.
Fig. 5. is an end elevation of part of boss or bearing.
A is a boss or bearing carried above each spindle C in the fixed rail B of the
frame; upon the said bearing, above and below, are cross geared wheels D and E,
the cross geared wheel D above the rail B is fixed upon the boss or bearing A,
whilst the cross geared wheel E below the said rail B is loose upon the boss or
bearing, it being attached to an enlarged loose cap or cup F partly covering the
drawing rollers J and K upon the inside; the cap or cup F has a thread or
worm F and upon the spindle of one of the drawing rollers J is a small star bevel
wheel G gearing into the thread F' of the cap F. as the cap revolves it moves the
drawing roller J which in turn operates the other drawing roller K which is kept
in contact with it by means of the springs L. (within slots in the bearing) which
act directly upon it. L' is a cover or guard.
Or should the cross geared wheel E be stationary the star wheel will revolve by
the action of the bearing A moving it within the worm F¹.
Each boss or bearing A and its cross geared wheel D is driven by the cross
geared wheels 'D' upon the horizontal shaft D which is the main driving shaft.
Each cross geared wheel E and cup or cap F is driven by a small cross, geared
wheel E upon the front horizontal shaft E3 in front of the. fixed rail B of the
frame, this shaft E receiving its motion by a series of change speed wheels such
as R, S, T, U, V, see Fig. 2. from the main shaft E or other source, so that the
speed can be altered to suit the various qualities of yarn and fibres being spun, and
put in and out of gear or reversed as required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is-
1. The use and employment of the star wheel G. cup F, and worm F¹ for
operating the drawing rollers J and K upon the bearings A in the manner and for
the purposes substantially as shown and described.
2. Within the rail B the combination of the bearings A cross geared wheels D
and E, cap F with thread F1 gearing with star bevel wheel G upon one of the
drawing rollers J and K which revolve and are driven in the manner and for the
purposes such as shown and described.
3. The general arrangement and construction of apparatus such as shown and
described.
