CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARATION AND SPINNING OF COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL OME, 1, EDMUND
HARTLEY, of Oldham, in the County of Lancaster, Mechanic, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Wesminster, the Eleventh day of December, in the twelfth year of Her reign,
and in the year of our Lord One thousand eight hundred and forty-eight, did,
for Herself, Her heirs, and successors, give and grant unto me, the said
Edmund Hartley, Her especial license, full power, sole privilege and
authority, that I, the said Edmund Hartley, my exors, admors, and assigns,
and such others as I, the said Edmund Hartley, my exors, adññiors, or
assigns, should at any time agree with, and no others, from time to
time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England and
Wales and the Town of Berwick-upon-Tweed, my Invention of " CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARATION
AND SPINNING OF COTTON AND OTHER FIBROUS SUBSTANCES;" in which said Letters
Patent is contained a proviso that I, the said Edmund Hartley, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edmund Hartley, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, is particularly described and
ascertained in and by the Drawings hereto annexed, and the following
explanation thereof (that is to say):-
My Improvements in Machinery or Apparatus to be employed in the Pre-
paration and Spinning of Cotton and other Fibrous Substances apply, first,
solely to those machines used in the preparation of cotton, known by the name
of "roving and slubbing frames," and have for their object the decrease of the
vibration or oscillation, and also the wear and tear of the spindles, and at
the same time allowing of their running at an increased velocity. The second
part of my improvements relates to those machines used for spinning cotton
and other fibrous substances, now generally called "self-acting mules," and
more especially to that class known as Roberts's Self-actors, which machines are
well known to practical cotton spinners, and require no further explanation.
This part of my Invention consists in a certain novel method of working the
"backing-off" motion, whereby certain parts of the machinery hitherto employed
are dispensed with. The practical application of my improvements will be
readily understood upon referring to the Drawing annexed, which is marked
with figures and letters of reference corresponding with those in the following
description thereof.
Fig. 1 is a front elevation of a roving spindle and flyer, showing the applica-
tion of my improvements thereto, and Fig. 2 is a side or edge view of the same.
a, a, is the spindle, and b, b, the flyer. The first part of my improvements in
machinery to be employed in the preparation of cotton consists in retaining
the diameter of the upper part of the socket of the flyer d as usual, and in
reducing the diameter of the lower portion c of the socket of the flyer to that
of the spindle a, the upper part of the spindle a being also reduced in order
to fit into it. The object of thus reducing the exterior of the lower portion of
the socket to the diameter of the spindle is in order to allow of the bobbin
working up as far as the shoulder d of the socket, in consequence of which
the spindle a and the arms b, b, of the flyer do not require to be so long, by
which means the weight of the spindle and flyer is reduced, and the spindle
may be run at an increased velocity.
The second part of my improvements in machinery or apparatus to
be employed in the preparation of cotton consists in placing the bevil
pinione (which drives the bobbin) upon a bush or tube f, instead of
placing it upon the bare spindle as heretofore. This bush or tube f
is of one and the same piece with the common bolster or bearing g
(see Fig. 2, in which the bevi! pinion e and its boss are represented in
section). By the application of this part of my Invention th vibration or

page_text: J
my
oscillation of the spindle is considerably diminished, an increased speed is also
attainable, and the wear and tear of the spindle itself is greatly decreased.
: That part of Invention which applies to machinery or apparatus to be
employed in spinning cotton, &c., is distinctly illustrated by Figs. 3 and 4..
Fig. 3 shews a plan or horizontal view of that part of the headstock of an
ordinary "self-actor," which governs or regulates the "backing-off" motion;
a, a, is the main shaft, or, as it is technically termed, "rim shaft;" b is the
"backing-off" pulley; c is the "horse-shoe spring," and d is a lever, to the
end of which the bowl e is attached; f is the cam, and g the cam shaft.
In my improved arrangement (a plan view of which is shewn at Fig. 4), the
horse-shoe spring c and lever d are dispensed with. Upon the cam shaft,
is a moveable cam h, constructed as represented in the Drawing, being so
adjustable on the shaft g as to admit of its being fixed or regulated to its
"proper position by means of the two nuts i and k, one on each side of the cam.
The principal object of this Invention consists in allowing the "backing-off"
motion to be regulated from the cam shaft, and preventing the sudden check
which is caused by the plan hitherto in use, as the motion in this case can be
regulated with the greatest nicety, by means of the two nuts i and k, as above
described.
Having thus described the nature and object of my said improvements,
together with the method of carrying the same into practical effect, I may
state in conclusion that I claim as my Invention,—
First, with regard to the machinery or apparatus to be employed in the
preparation of cotton for spinning, retaining the diameter of the upper part of
the socket of the flyer d as usual, and reducing the diameter of the lower part
of the socket c of the flyer to that of the spindle, together with shortening the
arms of the flyer for the
purpose above-mentioned.
Secondly, I claim the application, employment, or use of the bevil pinion e
which drives the bobbin, in combination with, and placed upon a tube or bush
as at f, instead of being placed upon the bare spindle as heretofore, in
"slubbing and roving frames;" and,
Thirdly, with regard to the machinery or apparatus for spinning cotton and
other fibrous substances, I claim the method of working the backing-off
motion (in self-acting mules), as exhibited in the Drawing, and above par-
ticularly described.
In witness whereof, I, the said Edmund Hartley, have hereunto set my
hand and seal, the Ninth day of June, One thousand eight hundred
