page_text: LETTERS PATENT to Benjamin Foster, of Denholme, in the County of
York, Manufacturer, and John Moore, of the same Place, Manager, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING
AND DOUBLING WOOL AND OTHER FIBROUS MATERIALS."
Sealed the 22nd July 1862, and dated the 29th January 1862.
PROVISIONAL SPECIFICATION left by the said Benjamin Foster and
John Moore at the Office of the Commissioners of Patents, with their
Petition, on the 29th January 1862.
We, BENJAMIN FOSTER, of Denholme, in the County of York, Manufac-
turer, and JOHN MOORE, of the same Place, Manager, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR SPINNING AND DOUBLING WOOL AND OTHER FIBROUS MATERIALS," to be as
follows:-
Our Invention relates to those spinning and doubling machines in which a
"cap" or "bell" is employed, and has for its object the prevention of snarls.
For this purpose we connect levers or similar apparatus to the bobbins,
whereby they may be raised, so as to cause them. to pass into the "caps
"bells," and these levers or other such apparatus we combine with that com-
monly employed for throwing off the driving strap, so that the two operations
may be effected simultaneously.

by the said Benjamin Foster and John Moore in the Great Seal Patent
Office on the 29th July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
FOSTER, of Denholme, in the County of York, Manufacturer, and JOHN
MOORE, of the same, Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said Benjamin Foster and John Moore, Her special license
that we, the said Benjamin Foster and John Moore, our executors, admi-
nistrators, and assigns, or such others as we, the said Benjamin Foster and
John Moore, 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 OR APPARATUS FOR SPINNING AND DOUBLING WOOL AND OTHER FIBROUS
MATERIALS," upon the condition, amongst others, that we, the said Benjamin
Foster and John Moore, by an instrument in writing under our hands and
seals, or under the hand and seal of one of us, 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 Benjamin Foster and. John Moore,
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 and accompanying Drawings (that is
to say):
Our Invention relates to those spinning and doubling machines in which a
"cap" or "bell" is employed, and has for its object the prevention of "snarls."
For this purpose we connect levers or similar apparatus to the bobbins
whereby they may be raised, so as to cause them to pass into the ".
caps" ör
"bells," and these levers or other such apparatus we combine with that com-
monly employed for shifting the driving strap, so that the two operations may
be effected simultaneously.

page_text: The above describes the essential. character of our Invention, and we will
now proceed to describe how the same may be carried into practical operation,.
reference being had to the accompanying Drawing, in which Fig. 1 is a front-
elevation of a portion of a spinning or doubling frame upon the aforesaid
principle, and Fig. 2 is an end elevation thereof; all of the ordinary parts are
not, however, shewn,.but only sufficient of them to explain the application of
our Invention..
The ordinary scroll or heart wheel shaft is at a, the cam 6 of which acts
against the lever c, turning upon a fixed centre at d. The lower end of this
lever is thus caused to act against another lever e turning upon a centre at f
and connected at its upper end to a rod g, which thus imparts a sliding motion.
to a bar h. To this bar is connected a series of chains, one of which is shewn
at passing over pullies k; and attached at their lower ends to arms extending.
from rods as at l. These rods are connected to the copping rail n, on which
the bobbins rest, and thus the copping motion is effected; the bobbins being
caused to pass upward into the "caps" or "bells" o, and downward therein
by the return motion of the copping rail. This is the ordinary arrangement,.
and is merely alluded to for the purpose of explaining the application of our.
Invention. Suppose, now, that the motion of the machine is arrested, the-
thread denoted by the red line, and which is thrown outward by centrifugal
force, does not receive the full amount of twist requisite until it passes the-
cap or edge, and is being wound on to the bobbin. Therefore when the
machine is stopped that portion of the thread which has received its full.
amount of twist tends to equalise itself with that upper portion of the thread
which contains less, and in so doing unwinds a certain quantity of yarn from.
the bobbin, which is liable to curl up into a "snarl," and it is to avoid this
that we apply the improvements now of be described; at q is to the ordinary stop-
rod running along the machine and connected at the end, not shewn in the
Drawing, to the driving strap in the ordinary manner; against this stop rod.
is a lever pressed thereto by a spring m, and confined by a notch, whereby.
the rod q is prevented from being drawn in the direction of the arrow by a
weight or spring. The lever r turns upon a centre at s, and its lower end carries
a latch t mounted upon a centre at u, but prevented from turning in the direc-
tion of the arrow, although at liberty to turn in the other direction.. Beneath
the latch t, which has an inclined plane on its end is a lever v, turning upon a
fixed centre at w, from which there extends another lever x projecting.
upwards, so as to occupy a position in a line with a stop y attached to the
bar h, before mentioned. When it is desired to arrest the motion of the
machine the attendant raises the lever v, by which means it is caused. to act

page_text: "
against the inclined plane upon the latch t, so as to cause the lever r to turn
upon its centre s; this operation will remove the lever from the notch of
the stop rod q, which will then be at liberty to be drawn forward by the spring
or weight, so as to throw the driving strap on to the loose pulley simulta-
neously with this operation; the turning of the lever v upon its centre w will
bring the lever a into contact with the stop y, by which means the bar h will
be slidden forward, so as to elevate the copping rail u, through the agency of
the usual chains i and rods before mentioned; the effect of this will
be the elevation of the bobbins within the " caps or "bells" o, and con-
sequently the taking up of that portion of yarn which would otherwise have
been at liberty to "snarl." The above description assumes that the stopping
of the machine is effected when the bobbins are at the lower part of their
copping motion; but we also provide means for effecting the object of our
Invention, should it be desired to stop the machine when the bobbins are at
the upper part of their copping motion, and when they cannot of course be
moved higher, and this we accomplish by providing means for first of all
lowering them. The toothed wheel, by which the "scroll" or "heart wheel
shaft is usually driven, is shewn at y*; in the ordinary machines this wheel is
fast upon its shaft, but we place it loosely thereon, and cause it to commu-
nicate motion to the said shaft by means of a clutch box z, the other half *,
of which clutch box slides with a feather upon its shaft. To this half is
connected a forked lever 1, turning upon a centre at 2, and connected to the
lever by a rod 3. Supposing it to be desired to stop the machine when the
bobbin is at the upper part of the lift, the attendant by raising the lever v
causes the lever r to turn upon its centre, as before described; this will cause
the other lever 1 to shift the half 2 of the clutch box out of gear with
the other half, and the scroll or heart wheel will be at liberty to turn
in a reversed direction, and thus permit the copping rail and bobbins to
descend by their own gravity. This will have taken place when a short
motion only of the lever v has been accomplished, the said motion being only
required, so far as to act upon the incline on the end of the latch t, and the
descent of the copping rail will have brought the stop y, which was in the
position shewn by dots when the bobbins were elevated against the lever x, and
a further turning thereof will act as before described, so as to cause the
bobbins to pass upward and take up the slackened thread.
Having thus described and ascertained the nature of our said Invention, and
the manner in which the same is to be performed, we desire it to be under
stood that we do not confine ourselves to the precise arrangement of mechanism
above described; but we claim as secured to us under the above in par

page_text: recited Letters Patent, the adaptation of mechanism to the above-mentioned
spinning and doubling machinery, whereby the bobbins may be raised into the
caps" or "bells" when the machine is to be stopped.
In witness whereof, we, the said Benjamin Foster and John Moore,
have hereunto set our hands and seals, this Twenty-seventh day of
July, in the year of our Lord One thousand eight hundred and
sixty-two.
