Year: 1878

page_text: LETTERS PATENT to Thomas Henry Rushton, of the Firm of Messieurs Dobson
and Barlow, of Bolton, in the County of Lancaster, Machine Maker, and
James Albinson, of the same Place, Foreman, for the Invention of "IMPROVE-
MENTS IN FRAMES FOR GASSING YARNS."
Sealed the 21st March 1879, and dated the 9th November 1878.
PROVISIONAL SPECIFICATION left by the said Thomas Henry Rushton and
James Albinson at the Office of the Commissioners of Patents on the 9th
November 1878.
THOMAS HENRY RUSHTON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, and JAMES ALBINSON, of the
same Place, Foreman. "IMPROVEMENTS IN FRAMES FOR GASSING YARN."
This Invention consists, first, in an improved apparatus for moving the gas
burner from under the yarn when required.
To the tube of the gas burner is fixed a small finger resting upon the ordinary
stop lever, which is held up by a catch lever resting upon a slide bar. When the
burner has to be moved to one side the attendant disconnects the catch from the
slide bar, and the weighted end of the stop lever drops and lifts the bobbin off the
friction pulley.
Secondly. In attaching one end of the slide bar supporting the catches above
referred to to the strap fork, and in moving the strap fork by a crank and handle.
When the strap fork is moved from the fast to the loose pulley the sliding bar is
moved end wise, and releases the catches, which then drop and lift the bobbins as
before described.
Thirdly. In self acting apparatus for stopping each bobbin when full; this is
effected by means of a lever supporting the bobbin, hinged to the ordinary stop
lever, and a second lever connected to the catch. When the bobbin is full the lever
supporting the bobbin is raised, and a regulating screw at its end acts on the second
lever, which releases the catch and allows it to drop to move the gas burner to one
side. The details of the apparatus for stopping all the bobbins at one time, and for
stopping each bobbin when full, may be varied.

the said Thomas Henry Rushton and James Albinson in the Great Seal Patent
Office on the 8th May 1879.
THOMAS HENRY RUSHTON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, and JAMES ALBINSON, of the
same Place, Foreman: "IMPROVEMENTS IN FRAMES FOR GASSING YARNS."
This Invention consists, first, in an improved apparatus for moving the gas
burners from under the yarn when required.
Secondly. In attaching one end of the slide bar supporting the catches to the
strap fork, and in moving the strap fork by a crank and handle or other equiva-
lents, whereby all the bobbins may be stopped simultaneously; and,
Thirdly. In self acting apparatus for stopping each bobbin when full; this is
effected by means of a lever supporting the bobbin hinged to the ordinary stop
lever.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 is an elevation partly in section of part of a gassing frame to which our
improvements are applied; and Fig. 2 is a front view of the same.
The line a represents the yarn or thread to be gassed; b, the gas burners; c, the
box containing the mixture of air and gas for the burners; d, the supply pipe; e, the
stop lever supported on the fulcrum stud e¹; e², the catch lever; and e³, the slide
bar; fis the bobbin on which the thread or yarn is wound when gassed; and 9,
the friction pulley by which the bobbin fis turned round. All these parts are inade
in the ordinary manner.
To the supply pipe d is fixed the finger d¹, resting upon the stop lever e, which is
held up by the catch lever e² resting upon the slide bar e³. When the burners have
to be moved to one side the attendant disconnects the catch lever e² from the slide
bar e in the usual manner, and the weighted end of the stop lever e then drops, and
lifts the bobbin f off the friction pulley g, thereby moving the burners away from
the yarn the moment that it ceases to be wound on the bobbin.
The second part of our Invention consists in stopping all the bobbins simulta-
neously when required; this may be accomplished in the following or in any other
equivalent manner. The slide bars es at each side of the machine are connected by
the stays h¹ to the starting rod h, to one end of which is fixed the strap fork i.
When the attendant moves the starting rod endwise the slide bars e³ are moved to
the extent required for liberating all the catch levers e2 and stop levers e, which
then drop and lift the bobbins of off the friction pulleys g; the end motion of the
starting rod also moves the strap fork i, to shift the driving strap from the fast
pulley j to the loose pulley j¹ to stop the frame.
The third part of our Invention consists of a self acting apparatus for stopping
each bobbin when full: The bobbins f are supported in the levers f', which are
hinged to the fulcrum stud e¹ of the stop levers e; at the end of each lever f¹ is a
regulating screw.f, which acts upon the tail end of the catch lever e². When a
bobbin is full the outer end of the lever f¹ is raised, and the screw f' then acts on
tail end of the catch lever e², which is thereby unlatched off the slide bar e³, thus
releasing the stop lever e, and lifting the full bobbin off the friction pulley. The
spring ffixed to the lever e acts as a friction break to prevent the overrunning of
the bobbin when lifted off the friction pulley g.
Having thus stated the nature of our Invention and described convenient
methods of carrying the same into operation, we wish it to be distinctly under-
stood that we do not intend to limit ourselves to the details given, as the apparatus
for stopping all the bobbins simultaneously, and for stopping each bobbin when full,
may be considerably varied without departing from the peculiar character of our
Invention.

page_text: We claim, firstly. The improved apparatus for moving the gas burners from
under the yarn, as shewn and described.
Secondly. The apparatus for stopping all the bobbins simultaneously, as shewn
and described, or any modification thereof; and,
Thirdly. The self acting apparatus for stopping each bobbin when full, as shewn
and described, or any modification thereof.
In witness whereof, I, the said Thomas Henry Rushton, for myself and on
behalf of the within named James Albinson, have hereunto set my hand and
seal, this Sixth day of May, One thousand eight hundred and seventy
nine.
