Year: 1876

page_text: LETTERS PATENT to Samuel Smith, of the Firm of J. & S. Smith, Machine
and Tool Makers, of Low Bridge Works, Keighly, in the County of York, for the
Invention of "IMPROVEMENTS IN DOUBLING AND TWISTING, AND IN APPARATUS
CONNECTED THEREWITH." A communication from abroad by Charles Fletcher
and Henry T. Wentworth, of Providence, Rhodo Island, United States of
A maxina
Sealed the 14th November 1876, and dated the 17th May 1876.
PROVISIONAL SPECIFICATION left by tho said Samuel, Smith at the Office
of the Commissioners of Patents on the 17th May 1876.
SAMUEL SMITH, of the Firm of J. & S. Smith, Machine and Tool Makers, of Low
"IMPROVEMENTS IN DOUBLING
Bridge Works, Keighly, in the County of York.
AND TWISTING, AND IN APPARATUS CONNECTED THEREWITH."
This Invention relates to employing a trap or apparatus for stopping the delivery
and twist simultaneously on the breakage of one or more threads, which apparatus
can be fitted to flyer, cup, or ring.
For this purpose in lugs formed on a bracket are fitted two or more spindles, on
which work brass tubes, having cast-iron flanges fixed to them; on the under sido
of the flanges are formed stop ribs, and on the top of the flanges are fitted pins
working in slots formed in the bottom flanges of the bobbins; the brass tubes and
the bobbins rotate together. On the bracket are fitted two or more rocking rods, on
which are fixed stop and balance wires; on the top of the balance wires are formed
hooks through which pass the threads. The bobbins with yarn having been placed
on the hollow brass tubes the threads are passed through the hooks, and the
tension of the threads holds the balance wires up and keeps the stop wires down,
allowing the bobbins to rotate, and the operation of doubling and twisting to pro-
ceed; but should a thread coming from either of the bobbins break, the balance lever
would fall on one side, causing the stop wire to lift and come in contact with the
rib formed underneath the flange of the brass tube and simultaneously stop the
delivery of both or more bobbins.

SAMUEL SMITH, of the Firm of J. & S. Smith, Machine and Tool Makers,
Low Bridge Works, Keighley, in the County of York. "IMPROVEMENTS IN DOUB-
LING AND TWISTING, AND IN APPARATUS CONNECTED THEREWITH." A communication
from abroad by Charles Fletcher and Henry T. Wentworth, of Providence, Rhode
Island, United States of America.
The said Invention relates to employing a trap or apparatus for stopping the
delivery and twist simultaneously on the breakage of one or more threads,
which apparatus can be fitted to flyer, cup, or ring.
For this purpose in lugs formed on a bracket are fitted two or more spindles, on
which work brass tubes, having cast-iron flanges fixed to them; on the under side
of the Ganges are formed stop ribs, and on the top of the flanges are fitted pins
working in slots formed in the bottom flanges of the bobbins; the brass tubes and
the bobbins rotato together. On the brackets are fitted two or more rocking rods,
on which are fixed stop and balance wires; on the top of the balance wires are
formed hooks through which pass the threads. The bobbins with yarn having
been placed on the hollow brass tubes the threads are passed through the hooks,
and the tension of the threads holds the balance wires up and keeps the stop wires
down, allowing the bobbins to rotate, and the operation of doubling and twisting
to proceed; but should a thread coming from either of the bobbins break, the
balanco lever would fall on one side, causing the stop wire to lift and come in
contact with the rib formed underneath the flange of the brass tube and simul-
taneously stop the delivery of both or more bobbins.
But in order to enable these improvements to be better understood I will pro-
ceed to describe the same by reference to the accompanying Drawing, in which
Figure 1 represents a side view of the improved trap shewing the metal tube,
lange, and bobbin in section; Figure 2, front view; Figure 3, back view; and
Figure 4, plan of the same; Figure 5 represents the under side of the flange with
stop rib, and Figure 6 the under side of a bobbin. Similar letters of reference aro
used in all the Figures to represent similar parts.
On the bracket A are formed lugs B, in which two or more spindles Care fixed;
on the spindles work brass or metal tubes D having metal flanges E fixed on them;
the under sides of the flanges E are formed with stop ribs F, and the upper sides
are fitted with pins G which work in slots H formed in the bottom flanges I of the
bobbins J; the brass or other metal tube and the bobbin rotate together. On the
bracket A are fitted in lugs K two or more rocking rods L, on which are formed
stop wires M and balance wires or levers N having on the tops hooks O through
which pass the threads P. The bobbins J with the yarn having been placed
on the metal tubes D, the threads P are passed through the hooks and the
tension of the threads holds the balance wires or levers N up and keeps the
stop wires M down, allowing the bobbins J to rotate and the operation of doub-
ling and twisting to proceed. Should a thread coming from either of the bobbins
break, the balance wire or lever N falls on one side causing the stop wire M to
lift and come in contact with the rib F formed underneath the flange E on
the brass or other metal tube D, and to simultaneously stop the delivery of both
or more bobbins.
Having thus described the Invention communicated to me, and the best means I
am acquainted with for carrying the same into effect, I would have it understood
that I do not confine myself to the precise details shewn and described as these
may be varied without departing from the peculiar character of the Invention; but
what I do claim is, the general arrangement, construction, and employment of trap
apparatus for stopping the delivery of the yarn and twist, simultaneously on the

page_text: breakage and cessation of delivery of one or more threads, substantially as herein-
before described and represented in the accompanying Drawing.
In witness whereof, I, the said Samuel Smith, have hereto set my hand
and seal, this Sixth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
