Year: 1875

page_text: LETTERS PATENT to Edward Whalley, of the City of Manchester,
Machinist, and Edward Weild, of the Firm of Messieurs William
Weild and Company, of the Gorebrook Iron Works, Longsight,
near Manchester aforesaid, Engineer, for the Invention of " IM-
PROVEMENTS IN MACHINERY FOR DOUBLING, TWISTING, AND WINDING."
PROVISIONAL SPECIFICATION left by the said Edward Whalley and
Edward Weild at the Office of the Commissioners of Patents, with
their Petition, on the 27th August 1875.
We, EDWARD WHALLEY, of the City of Manchester, Machinist, and
EDWARD WEILD, of the Firm of Messieurs William Wield and Company,
of the Gorebrook Iron Works, Longsight, near Manchester aforesaid,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR DOUBLING, TWISTING, AND WINDING," to be
as follows:-
The object of our Invention is to arrest the motion of the top and
bottom rollers or of the bobbins of doubling, twisting, and winding..

-machines-simultaneously, to stop the supply of yarn carried forward by
them, and consequently to prevent the waste caused by lapping.
In machines of the above description of the usual construction it is
customary to lift the top roller out of contact with the bottom roller,
which is made in a continuous length. Now our Invention consists in
supporting both of the top and bottom rollers in a swivel frame, and in
driving all the bottom rollers by spur pinions on a shaft extending the
whole length of the machine.
The swivel frame above referred to is held down by a weighted catch
to hold the pinions on the bottom rollers in gear with the pinions on the
shaft. The yarn, passing from the top roller to the spindle and fly or to
the bobbin, is taken through a guide wire in a tumbler catch.
So long as the yarn remains unbroken the tumbler catch is held up by
the yarn, and the weighted catch holds the swivel frame in position for
driving the rollers, but when an end breaks the front end of the tumbler
catch drops on to the weighted catch, which then releases the swivel
frame, and at the same time the back end of the tumbler catch comes
against the pinion on the bottom roller, and lifts it out of gear with its
driving pinion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Edward Whalley and Edward Weild in the Great
Seal Patent Office on the 16th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wę, EDWARD
WHALLEY, of the City of Manchester, Machinist, and EDWARD WEILD,
of the Firm of Messieurs William Weild and Company, of the Gore-
brook Iron Works, Longsight, near Manchester, aforesaid, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of August, in
the year of our Lord One thousand eight hundred and seventy-five,
in the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Edward Whalley and
Edward Weild, Her special licence, that we, the said Edward Whalley.

page_text: and Edward Weild, our executors, administrators, and assigns, or such
others as we, the said Edward Whalley and Edward Weild, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time, and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
" IMPROVEMENTS IN MACHINERY FOR DOUBLING, TWISTING, AND WINDING,"
upon the condition (amongst others) that we, the said Edward Whalley
and Edward Weild, our executors or administrators, by an instrument
in writing under our, or their, or one of our or their hands and seals,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Edward Whalley and Edward
Weild, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):-
The object of our Invention is to arrest the motion of the top and
bottom rollers or of the bobbins of doubling, twisting, and winding
machines simultaneously, to stop the supply of yarn carried forward by
them, and consequently to prevent the waste caused by lapping.
In machines of the above description of the usual construction it is
customary to lift the top roller out of contact with the bottom roller, .
which is made in a continuous length. Now our Invention consists in
supporting both the top and bottom rollers in a swivel frame, and in
driving all the bottom rollers by spur pinions on a shaft extending the
whole length of the machine.
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, in which Figs. 1 and 2 are front views; and Figs. 3
and 4 are end views of part of a throstle doubling frame to which our
improvements are applied.
a, a, are the bottom rollers, which instead of being made in continuous

page_text: rollers 6, as shewn in Fig. 2. The pivots of the top and bottom rollers
are supported in slots in the cap bars c, which are fixed in the stands d
bolted to the roller beam e. The stands d are provided with bearings
for the shaft, which extends the whole length of the machine. To
this shaft are fixed the spur pinions f¹, which gear into and drive the
pinions a¹ on the bottom rollers a. The cap bars c support the trunnions g¹
of the swivel frames g, one of which is shewn detached in Fig. 5, and
these swivel frames are made with V shaped bearings, in which the
pivots of the bottom rollers revolve. The front ends of the swivel
frames are held down by the weighted catches h, which are jointed to
the brackets i, and these brackets also support the tumbler catches j, to
which the guide wires j¹ are fixed. The yarn on leaving the guide wire
is taken, as usual, over a, guide rod %, and thence to the flyer on the
spindle, as shewn by a dotted line.
}
The mode of operation is as follows:-So long as the yarn remains
unbroken the tumbler catch j is held up by the yarn, and the weighted
catch holds the swivel frame g in position for driving the rollers, but
when an end breaks, the front end of the tumbler catch j drops on the
projecting arm ¹ of the weighted catch h, which then releases the
swivel frame g, which is then raised by the preponderating weight of its
outer end, and at the same time the back end of the tumbler catch j
comes against the pinion a¹ on the bottom roller a, and lifts it out of
gear with its driving pinion f¹. By this means both the top and bottom
rollers are raised, and as they cease to revolve the supply of yarn is
stopped, and lapping is prevented.
When the yarn or thread is wound on a bobbin resting upon the
bottom roller a it is drawn off cops or bobbins placed in front of the
machine; as usual in this casc also the tumbler catch j is held up
by the yarn or thread, and when an end breaks or fails the swivel
frame lifts the pinion a¹ out of gear with the driving pinion f¹ to stop
the supply.
I
Having thus stated the nature of our Invention, and described a
convenient manner of performing the same, we wish it to be understood
that we do not intend to limit ourselves to the details given, as the same
may be varied or modified, but what we do claim is,—
First. Making the bottom rollers of machines for doubling, twisting,
and winding of the same length as the top rollers, and disconnecting.
