Year: 1879

page_text: LETTERS PATENT to Walter Garnett, Spinner, and Thomas Smith, Overlooker,
both of Halifax, in the County of York, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR PREVENTING WASTE IN THE SPINNING, TWISTING, AND
DRAWING OF FIBRES."
Sealed the 27th December 1879, and dated the 22nd September 1879.
PROVISIONAL SPECIFICATION left by the said Walter Garnett and Thomas
Smith at the Office of the Commissioners of Patents on the 22nd September
1879.
WALTER GARNET, Spinner, and THOMAS SMITH, Overlooker, both of Halifax, in
the County of York. "IMPROVEMENTS IN APPARATUS FOR PREVENTING WASTE IN
THE SPINNING, TWISTING, AND DRAWING OF FIBRES."
The object of our Invention is to prevent waste in spinning frames for two folds,
when an end is down, to break the other thread and so prevent it running to
waste. Our apparatus is as follows:-On a stand or frame carrying the bobbins
we employ two balance levers (pivotted or hinged in suitable bearings) carrying
guides for the threads; the levers have adjustable balance weights at one end, their
other ends terminating in fingers; the fingers of each lever coming under its corres-
ponding bobbin, are so arranged that when the threads are whole and tight, the
fingers of the levers are clear of or below the bottoms of the bobbins, but when an
end is down or broken, the levers tilt or move, bringing the fingers against the
bottom of the bobbin, cap, or plate, in or on which there are recesses, pins or pro-
jection (preferably we use a loose cap or plate) with which the finger ends engage
and so stop the bobbins, breaking the thread, thus preventing waste; another arm
or crank (over which the thread passes when whole) is hung or pivoted so that
when piecening up by turning the arm back on its axis it falls upon the levers and
holds the finger ends clear of the bobbin bottoms, so facilitating piecening up. The
above apparatus is applicable for any kind of twofold frames.

WALTER GARNETT, Spinner, and THOMAS SMITH, Overlooker, both of Halifax, in
the County of York. "IMPROVEMENTS IN APPARATUS FOR PREVENTING WASTE IN
THE SPINNING, TWISTING, AND DRAWING OF FIBRES."
The object of our Invention is to prevent waste in spinning, and twisting frames
for two folds, three folds, or four folds, when an end is down to break the other
threads and so preve ntit running to waste.
Our apparatus is specially applicable to roller twisting frames, and is
constructed as follows: On a stand or frame carrying the bobbins, we
employ a corresponding number of balance levers (pivotted or hinged in
suitable bearings) carrying guides for the threads; the levers may be balanced
or have adjustable balance weights at one end, their other ends terminating
in fingers, the fingers of each lever coming under or over its opposite cor-
responding bobbin; the fingers of the levers are so arranged that when the
threads are whole and tight, the fingers of the levers are clear, or below the bottoms
of the bobbins, but when an end is down or broken the levers tilt or move, bringing
the fingers against the bottom or other part of the bobbins, caps, or plates, in or on
which there are recesses, pins, or projections (preferably we use a loose cap or plate)
with which the finger ends engage, and so stop the bobbins, breaking the thread,
thus preventing waste; the thread from the bobbin passes to the guide of its
corresponding lever, but the finger of the lever comes under its opposite bobbin, so
that when a thread breaks, or bobbin runs out the other bobbins are stopped and
threads broken in turn, so preventing single or three fold; another arm or crank is
bung or pivotted so that by turning the arm back on its axis it falls upon the levers
and holds the finger ends clear of the bobbin bottoms, so facilitating piecening up.
The above apparatus is applicable for any kind of twisting and number of threads.
The guides we construct not in the hook like form as generally used, but make
them longer so that the threads can traverse, and by so doing the guides are more
serviceable and do dot wear at one part, but wear evenly across the whole surface
of the guide.
Such being the nature and object of this our said Invention, we will now proceed to
describe the same in detail, and in order that the Invention may be fully understood,
we have hereunto annexed two Sheets of Drawings illustrative thereof, and marked
the same with Figures of reference, the same Figure referring to the same part in
the various views.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is front elevation of our Invention for two folds, showing threads
unbroken; Fig. 2 is an end elevation showing guides; Fig. 3 is a plan view of
Fig. 1; Fig. 4 shows front elevation of our Invention as applied for four folds,
threads being broken; Fig 5 is an end view showing the arrangement of guides;
Fig. 6 is a plan view of Fig 4; Fig 7 is a general view for twofolds, the threads
passing under the guides; Figs. 8, 9, 10, 11, 12, and 13 are details.
Sheet 2, Figs. 14, 15, 16, and 17, show modifications of fingers engaging
with bobbins Figs. 1, 2, and 3. 1 is the board or stand carrying the
hobhing 2 and 2. 4 and
K

page_text: of the lever 5 goes to the bobbin 2; the thread 10 of the bobbin 2 passes over the
guide 8 of the opposite levers 4, and between traverse guide 15, thence to the
drawing rollers 16, 16; 17, 17, are loose caps or plates at the bottom of the bobbins;
on the plates are pins 18, 18, fitting into corresponding holes in the bobbins, the
caps or plates 17, 17, having recesses 19 or pins or projections at their under or
over sides, in or on which the ends of the fingers engage; the levers 4 and 5 are
made heaviest at their guide ends if the thread passes under the guide as at Fig. 7,
but heaviest at their other ends when the thread passes over the guide; so long as
the threads are entire or whole the fingers are clear of the caps or plates of the
bobbins; but so soon as a bobbin runs out or thread breaks, its lever tilts and
engages with the cap or plate of the opposite bobbin, stopping it; the drawing rollers
continue their rotation and break the thread. An arm 20 hinged at 6 when moved
in the direction of the arrows and dotted lines falls on and holds the levers clear of
the bobbins whilst pieceining up; the fingers, levers, and guides may be constructed
all in one piece of metal if desirable. The Invention is applicable to any number
of threads, the levers and bobbins requiring increasing accordingley.
Fig. 7 shows a general view of apparatus for twofolds, the threads passing under
the guides and thence to the drawing rollers.
Figs. 8, 9, 10, and 11 show different forms of caps or plates.
Figs. 12 and 13 show forms of traverse guide.
Having thus fully described the nature and particulars of this our said Invention
together with the manner in which the same may be performed or carried into
practical effect, we would have it understood that what we claim as our
Invention is,-
Firstly. The combination of levers such as 4 and 5 or 4ª and 5ª acting upon the
bobbins in the manner and for the purpose substantially as described and
illustrated.
Secondly. The arm 20 acting upon the levers in the manner and for the purpose,
substantially as described and illustrated.
In witness whereof, we, the said Walter Garnett and Thomas Smith, have
hereunto set our hands and seals, this Eighteenth day of March, in the year
of our Lord One thousand eight hundred and eighty.
