"
PROVISIONAL SPECIFICATION left by the said George Knowles at the Office
of the Commissioners of Patents on the 1st April 1876.
GEORGE KNOWLES, junior, of Bolton, in the County of Lancaster, Cotton Spinner.
IMPROVEMENTS IN MULES FOR SPINNING."
My Invention refers to that part of mules for spinning known as the "nosing
peg," or to an equivalent therefor, the office of which, as is well known, is to act
upon the winding on chain, and the object of my Invention is to cause the action
to take place gradually upon the said chain and with a governable tension so as to
avoid what are commonly called "cut places." To accomplish this I cause the
nosing peg" or its equivalent to act upon the winding on chain through an elastic
medium, whereby sufficient rigidness is obtained to regulate the winding on but in
a gradual manner.
The following will illustrate my Invention:-The nosing peg is mounted in a
fork carried by the radial arm and is forced forward by spiral springs; when there-
fore the peg is brought into contact with the chain by the usual means the said
springs resist but slightly at first but gradually acquire sufficient tension to
complete the necessary action upon the chain. The position of the peg may be
adjusted by the attendant in any ordinary manner, but the yielding springs will
compensate for an undue movement of the said peg.
As a modification of the foregoing arrangement I use an extra chain connected
at one end to the winding on chain, and at the other to the radial arm, with an
intervening spring. The "nosing peg" in this instance represented by an attach-
ment or guide of the chain.

Seal Patent Office on the 1st November 1876.

"IMPROVEMENTS IN MULES FOR SPINNING."
My Invention refers to that part of mules for spinning known as the nosing peg,
or equivalent therefor, the office of that being, as is well known, to act upon the
winding on chain, and the object of my said Invention is to cause the action to take
place gradually upon the said chain, and with a governable tension so as to avoid
what are commonly called cut places. To effect this I cause the nosing peg or its
equivalent to act upon the chain through an elastic medium whereby sufficient
rigidness is obtained to regulate the winding on but in a gradual manner.
In the accompanying Drawing Fig. 1 represents a portion of the winding on
motion of a mule; Fig. 2, a plan view; and Fig. 3, a detached view of the part which
acts as the nosing peg.
At a is the quadrant or radial arm; at b, the winding on chain; and at c, the drum.
To the radial arm a is fixed a bracket d provided with a boss e which is tapped for
the reception of a screw f; this screw fis connected by a socket at his lower end to
cross piece g, between which and another there are springs i, i, mounted
on rods k, k, and the last-mentioned parth is situate over the chain band constitutes
the nosing peg; at l is a rod attached to the cross piece g and passing through the
boss e whereby the said part is prevented from turning. The action of the nosing
peg upon the winding on takes place in the usual manner excepting that when it
arrives in contact with the said chain it does so through the medium of the springs
i, i, and the force therefore is through an elastic medium and comes gradually into
operation, and the action may be regulated at pleasure by turning the screw f
upward or downward and so causing the plate g to compress the springs i, i, or
allow them to expand the nosing peg / when the radial arm rises, being in contact
with stops m, m. At n is a nut for confining the screw f to any desired position.
The above description points out the particular arrangement of my Invention
which I use, but it will be evident that the same may be varied by applying the
elastic medium in other forms.
Having thus described and ascertained the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent the use of a
nosing peg or substitute therefor acting through the medium of springs or other
clastic appliance.
In witness whereof, I, the said George Knowles, junior, have hereunto set
my hand and seal, this Thirty-first day of October, in the year of our Lord
One thousand eight hundred and seventy-six.
