Lancaster, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF.
SELF-ACTING MULES USED FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 28th March 1877, and dated the 3rd January 1877.
PROVISIONAL SPECIFICATION filed by the said Benjamin Platt at the Office
of the Commissioners of Patents on the 3rd January 1877.

BENJAMIN PLATT, of Ahston-under-Lyne, in the County of Lancaster. "Iм-.
PROVEMENTS IN THE CONSTRUCTION OF SELF-ACTING MULES USED FOR SPINNING.
COTTON AND OTHER FIBROUS MATERIALS."
The object of this Invention is to dispense with the use of the ropes or bands and
the scrolls hitherto employed for effecting going in and out of the carriage to and
from the rollers, and the driving of the spindles by the tin roller.
To effect the movement of the carriage I mount a long screwed shaft in suitable
bearings near the floor, and attached to the end of the carriage I have a brackėt
provided with a screwed nut working upon the long screwed shaft; rotary move-
ment being given to this screwed shaft in one direction from the back shaft by
means of a pair of bevil wheels effects the drawing out of the carriage from the
rollers during the spinning, and a rotary motion in the reverse direction, and at
an increased speed obtained by bevil gear connected to the "friction motion" effects
the running in of the carriage during the winding on of the yarn.
To drive the "tin roller" for actuating the spindles I mount a long shaft parallel
with the screwed shaft, and about level with the centre of the tin roller. Upon
this shaft a bevil wheel is mounted on a long key or feather, so that it revolves
with it but can slide along the shaft. This bevil wheel gears with a similar wheel
keyed on the end of the tin roller shaft, and is moved to and fro on the shaft with
the motion of the carriage by means of a double clutch fixed to the latter.

the said Benjamin Platt in the Great Seal Patent Office on the 3rd July 1877.
BENJAMIN PLATT, of Ashton-under-Lyne, in the County of Lancaster. "IM-
PROVEMENTS IN THE CONSTRUCTION OF SELF-ACTING MULES USED FOR SPINNING
COTTON AND OTHER FIBROUS MATERIALS."
The object of this Invention is to dispense with the use of the ropes or bands
and the scrolls hitherto employed for effecting going in and out of the carriage to
and from the rollers, and the driving of the spindles by the tin roller.
Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof:
Fig. 1 in the annexed Drawings represent an elevation, Fig. 2 a ground plan, of
so much of the headstock of a mule as is necessary to illustrate my Invention.
a, a, is part of the framing of the headstock; b, b, the main driving shaft ;
and c, c, the spindle carriage.
To effect the movement of the carriage c, c, I mount a long screwed shaft d, d;
in suitable bearings; and attached to the end of the carriage c, c, I have a bracket
provided with a screwed nut e, e, working upon the long screwed shaft d, d;
rotary movement being given to this screwed shaft d, d, in one direction from the
back shaft f, f, by means of a pair of bevil wheels g, g, effects the drawing out of
the carriage c, c, from the rollers during spinning, and a rotary motion in the reverse
direction, and at an increased speed, obtained by bevil gear connected to the "friction
motion" h, h, effects the running in of the carriage c, c, during the winding on of the
yarn.
To drive the "tin roller".i, i, for actuating the spindles I mount a long shaft
parallel with the screwed shaft h, k, and above the level of the tin roller. Upon
this shaft a bevil wheel is mounted on a long key or feather, so that it revolves
with it but can slide along the shaft k, k. This bevil wheel, gears with a similar.
wheel'm on a short shaft, keyed on the other end of which is a pinion gearing with
another pinion on the tin roller shaft ix, and is moved to and fro on the shaft with
the motion of the carriage by means of a double clutch fixed to the latter.
Having now described the nature and object of my said Invention, together with.
the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I clain as my Invention, the general
construction and arrangement of apparatus above described and illustrated by the
Drawing annexed, whereby I am enabled to dispense with the ropes or bands and
scrolls hitlierto employed for effecting the going in or out of the carriage and for
driving the tin roller; and especially I claim, firstly, the use of the long screwed
shaft working in a screwed nut attached to the spindle carriage; and, secondly, the
bevil wheel moving with the carriage and sliding on a long key or feather, and
gearing with a similar wheel on the tin roller shaft.
In witness whereof, I, the said Benjamin Platt, have hereunto. set my hand
and seal, this Thirtieth day of June, in the year of our Lord One thousand
eight hundred and seventy-seven.
