Year: 1878

page_text: LETTERS PATENT to Edmund Tweedale, Manager, and Samuel Tweedale,
Foreman Mechanic, both of Accrington, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING
. AND DOUBLING FIBRES."
Sealed the 24th December 1878, and dated the 22nd July 1878.
PROVISIONAL SPECIFICATION left by the said Edmund Tweedale and
Samuel Tweedale at the Office of the Commissioners of Patents on the 22nd
July 1878.
EDMUND TWEEDALE, Manager, and SAMUEL TWEEDALE, Foreman Mechanic, both
of Accrington, in the County of Lancaster. "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING AND DOUBLING FIBRES."
This Invention relates,―
Firstly. To improved appliances for facilitating doffing or removal of the bobbins
or spools.
Secondly. To improved apparatus to be employed when building or forming the
cop bottoms.
Thirdly. To improved apparatus for lowering the lifter rail when the bobbins or
spools are filled, or so lowering the said rail when desirable.
Firstly. In order to facilitate doffing we construct the "wire" or guide rail in
sections or parts, each hinged as heretofore, but provided with V or other shaped
openings, and mount the said rail upon supporting and wedging or binding studs
and slots; the said rail is connected with a lever motion and cross shaft (so as to
connect the rail on each side of the "frame" or machine). When necessary to doff
the bobbins or spools the lever is used and slides the rails longitudinally, so as to
bring the V or other recesses over or on a vertical line above the bobbins that the
[Price 6d.]

necessity of folding or turning back the same or its separate hinged parts as
heretofore.
Secondly. For building or forming the cop bottoms, we employ in connection
with the lifter chain a double T headed piece, which so acts upon the chain by
means of a clip piece as to move the chain out of a vertical line, causing for the
time being a slower travel or partial dwell of the chain, giving the required time
for building up or winding on the cop bottom.
Thirdly. We mount the chain pulley so as to be concentric in its revolution in
ordinary working, but eccentric to a lowering lever or gear, that when moved by
the lever it makes a partial eccentric revolution, slackening the lifter chain, and
permitting the lifter rail to descend, for purpose referred to.

the said Edmund Tweedale and Samuel Tweedale in the Great Seal Patent
Office on the 22nd January, 1879.
EDMUND TWEEDALE, Manager, and SAMUEL TWEEDALE, Foreman Mechanic, both
of Accrington, in the County of Lancaster. "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SPINNING AND DOUBLING FIBRES."
This Invention relates,-
Firstly. To improved appliances for facilitating doffing or removal of bobbins or
spools.
Secondly. To improved apparatus to be employed when building or forming the
cop bottoms.
Thirdly. To improved apparatus for lowering the lifter rail when the bobbins or
spools are filled, and for lowering the said rail when desirable.
Firstly. In order to facilitate doffing, we construct the "wire or guide rail in
sections or parts, each hinged as heretofore, but provided with V or other shaped
openings, and mount the said rail upon supporting and wedging or binding studs
and slots. The said rail is connected with a lever motion and cross shaft so as to
connect the rail on each side of the frame or machine. When necessary. to doff
-the-bobbins or spools the lever is used, and slides the rails "longitudinally," so aș
to bring the V or other shaped recesses over or on a vertical line above the bobbins
that the latter can in the doffing or "lifting off" clear the wire or guide rail,
without the necessity of folding or turning back the same on its separate hinged
parts as heretofore.
Secondly. For building or forming the cop bottoms, we employ in connection
with the lifter chain a double T headed piece, which so acts upon the chain by
means of the clip piece as to move the chain out of a vertical line, causing for the
time being a slower travel or partial "dwell" of the chain, giving the required time
for building up or winding on the cop bottom.
Thirdly. We mount the chain pulley so as to be concentric in its revolution in
ordinary working, but eccentric to a lowering lever (or by gear) that when moved
by the lever it makes a partial eccentric revolution, slackening the lifter chain, and
permitting the lifter rail to descend apart from and independant of its ordinary
traverse.
Such being the nature and object of this our said Invention, in order that the
particulars thereof may be fully understood, we have hereunto annexed two Sheets
of Drawings, and reference is given to the several views by aid of figures and
letters.
Referring now to the first part of our Invention, Fig. 1 is a front elevation;
Fig. 2, a plan view; and in order to facilitate doffing we construct the "wire" or
guide rail in sections or parts A, A, A, each hinged as heretofore, but provided
with V or other shaped openings B, and mount the said rail upon supporting and
wedging or binding studs C and slots D. The said rail is connected with a lever
motion E, E, and cross shaft F, so as to connect the rail on each side of the frame
or machine. When necessary to doff the bobbins or spools the lever E is used, and
slides the rails A, A, A, longitudinally, so as to bring the V or other shaped recesses
B over or on a vertical line above the bobbins G (see Fig. 2) that the latter can in
the doffing or "lifting off" clear the "wire or guide rail, without the necessity of
folding or turning back the same on its separate hinged parts as heretofore.
"
The second part of our Invention is shown on Sheet 2 by Figs. 3 and 4, 5 and 6.
(The latter two views enlarged).
For building or forming the cop bottoms we employ in connection with the
lifter chain Ha pin or stud J, which, on entering the fork of the clip piece K by
means of the said pin J and the tension on the said chain, the fork is caused
to move on its centre, and thereby force the chain out of the vertical line, giving
the required time for building up or winding on the cop bottom.

page_text: Figs. 3 and 4 also illustrate the third part of our Invention; for lowering the
lifter rail we mount the chain pulley L, so as to be concentric, in its revolution in
ordinary working, but eccentric to a lowering lever M, that when moved by the.
lever M it makes a partial eccentric revolution, slackening the lifter chain H, and
permitting the lifter rail N to descend apart from and independant of its ordinary
descent.
Having thus fully described the nature and particulars of this our said Invention,
and the manner in which the same is to be performed, we would have it understood
that what we claim as our Invention is,-
Firstly. The guide rail A, A, provided with V or other shaped openings, and
having the lateral traverse or sliding motion by means and for purpose described.
Secondly. The combination and use of the clip piece K and stud or pin J for
acting upon the lifter chain H, in manner and for purpose described and shown.
Thirdly. The combination of chain pulley L and lever M, arranged as and acting
in manner and for purpose described.

have hereunto set our hands and seals, this Eighteenth day of January, in
the year of our Lord One thousand eight hundred and seventy-nine.
