Year: 1865

page_text: LETTERS PATENT to Charles Denton Abel, of No. 20, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Patent Agent,
for the Invention of "IMPROVEMENTS IN THROSTLE SPINNING FRAMES."-
A communication from abroad by Charles Leyherr, of Laval, Mayenne,
in the Empire of France.
Sealed the 4th July 1865, and dated the 27th Jauuary 1865.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at
the Office of the Commissioners of Patents, with his Petition, on the
27th January 1865.
I, CHARLES DENTON ABEL, of No. 20, Southampton Buildings, Chancery
Lane, in the County of Middlesex, Patent Agent, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THROSTLE SPINNING FRAMES," to
bo as follows:-
This Invention has reference to a description of throstle spinning frame for
which Letters Patent were granted to Samuel Dreyfous, bearing date the
18th January, 1862, No. 187. One of tho present improvements has refer-
ence to the form of the flyers. The present improved form of flyer consists of
a cylindrical tube, having collars at its upper and lower ends, at which points
it is supported by and revolves in two bearings formed in two transverse bars
or plates attached to the framework. This tube has projecting upwards from
its upper end a forked arm, the union of the fork being situated centrally over
the tube, where it is provided with a loop, whilst at its lower extremity the
tube is provided with two arms or prongs, projecting downwards, similar to

page_text: those of the ordinary flyer, and made to taper towards their extremities where
they are provided with loops or eyelets. The yarn or roving is conducted
from the drawing rollers through the loop or eyelet at the end of the before-
mentioned forked arm, it then passes through a second loop fixed at the upper
end inside the tube, whence it is conducted down through the tube, and after
being twisted once or twice round one of the lower arms it passes through the
loop or eyelet at the end of such arm on to the cop spindle. For imparting
motion to the flyer a whirl is fixed to the tube between its two bearings,
round which whirl a gut passes from the main drum, as in the arrangement
described in the Specification to the before-mentioned Letters Patent.
Another improvement relates to the mode of carrying the cop spindles, and
regulating the motion of the same. In place of each cop spindle being carried
by a separate bracket, as in the former arrangement, they are supported at
their lower ends by step bearings carried by the copping rail, and they run in
upper bearings all formed in one and the same transverse bar, also carried by
the copping rail. For producing the varying friction upon the cop spindles,
so as to regulate the winding on, in place of the mode of fixing and actuating
the weighted friction cords described in the before-mentioned Specification, a
transverse bar is fixed to the copping rail, behind the cop spindles, to which
bar the ends of the weighted cords are attached, and whence they are led
against the cop spindle, and then over pullies situated upon a rod passing
along the front of the cop spindles, which rod has a screw thread formed upon
it for the purpose of adjusting the position of the pullies. This rod is
attached to a bar supported by the copping rail, and receiving a reciprocating
motion in front of the cop spindles by the same mechanism as was described
in the before-mentioned Specification for moving the rod over which the
friction cords were in that case suspended.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed.
by the said Charles Denton Abel in the Great Seal Patent Office on
the 21st July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
DENTON ABEL, of No. 20, Southampton Buildings, Chancery Lane, in the
County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of January, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year

page_text: of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Charles Denton Abel, Her special licence that I, the said
Charles Denton Abel, my executors, administrators, and assigns, or such others
as I, the said Charles Denton Abel, my 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, excrcise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THROSTLE SPINNING FRAMES," a communication to me
from abroad by Charles Leyherr, of Laval, Mayenne, in the Empire of
France, upon the condition (amongst others) that I, the said Charles Denton
Abel, my executors or administrators, by an instrument in writing under my,
or their, or one of 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 I, the said Charlos Denton Abel, do hereby declaro
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawing, and to
the figures and letters marked thereon, that is to say:-
This Invention has reference to a description of throstle spinning frame for
which Letters Patent were granted to Samuel Drey fous, bearing date the
18th January, 1862, No. 137. One of the present improvements has refer-
ence to the form of the flyers. The present improved form of flyer consists
of a cylindrical tube having collars at its upper and lower ends, at which
points it is supported by and revolves in two bearings formed in two trans-
verse bars or plates attached to the framework. This tubo has projecting
upwards from its upper end a forked arm, the union of the fork being
situated centrally over the tube, where it is provided with a loop, whilst at its
lower extremity the tube is provided with two arms or prongs projecting
downwards, similar to those of the ordinary flyer, and made to taper towards
their extremities, where they are provided with loops or eyelets. The yarn
or roving is conducted from the drawing rollers through the loop or eyelet at
the end of the before-mentioned forked arm, it then passes through a second
loop fixed at the upper end inside the tube, whence it is conducted down
through the tube, and after being twisted once or twice round one of the
lower arms it passes through the loop or eyelet at the end of such arm on to

page_text: the cop spindle. For imparting motion to the flyer a whirl is fixed to the
tube between its two bearings, round which whirl a gut passes from the main
drum, as in the arrangement described in the Specification to the before-men-
tioned Letters Patent.
Another improvement relates to the mode of carrying the cop spindles and
regulating the motion of the same. In place of each cop spindle being
carried by a separate bracket as in the former arrangement, they are supported
at their lower ends by step bearings carried by the copping rail, and they run
in upper bearings all formed in one and the same transverse bar, also carried
by the copping rail. For producing the varying friction upon the cop
spindles so as to regulate the winding on, in place of the mode of fixing and
actuating the weighted friction cords described in the before-mentioned Speci-
fication, a transverse bar is fixed to the copping rail behind the cop spindles,
to which bar the ends of the weighted cords are attached, and whence they
are led against the cop spindles, and then over pullies situated upon a rod
passing along the front of the cop spindles, which rod has a screw thread
formed upon it for the purpose of adjusting the position of the pullies. This
rod is attached to a bar supported by the copping rail, and receiving a reci-
procating motion in front of the cop spindles by the same mechanism as was
described in the before-mentioned Specification for moving the rod over which
the friction cords were in that case suspended.
On the accompanying Drawing is shewn the throstle spinning frame with
the before described improvements. Figure 1 shews a front elevation of the
machine; Figures 2 and 3 are end views; Figure 4 is a sectional plan of
the same; Figures 5 and 6 shew respectively a detached view and a transverse
section through the same of the mechanism for obtaining the variable up-and-
down motion of the copping rail; Figure 7 shews an enlarged sectional
elevation of the improved By F, and Figure 8 shews a sectional elevation
of the improved mechanism for obtaining the variable drag of the cop
spindles. The same letters of reference indicate the same parts in each
of the Figures. As the general arrangement, and mode of action of those
parts of the machine which do not form the subject matter of the present
improvements are just the same as described in the Specification to the
herein-before mentioned Letters Patent they need not here be further
described, and the letters of reference upon such old parts only serve to
indicate them more clearly in the different views.
The improved fly F consists of the tubef having two collars at its upper]
end, and one at its lower end, by which it is supported in bearings formed in
the rails c, d, carried by the framing A, B, a, b. From the top of the tube f

page_text: projects the forked arm g, terminating in a loop or eye h situated centrally.
over the tube, whilst at the lower end it is provided with two tapering arms
jj, also terminating in loops as shown. The yarn or roving indicated by the
blue line is conducted from the drawing rollers D, D, through the loop h, and
then passes through one of the two loops k at the top of the tube f, through
which it is then led down and is twisted once or twice round one of the arms
j and finally passes through the loop of the latter on to the cop spindlo G.
Rotary motion is imparted to the flys F from the drum H by means of cords
passing from the latter. round the small pulley or whirl i upon the tube f.
Figure 8 shows in detail the improved arrangement for obtaining the.
variable drag on the cop spindles required, for regulating the winding on.
The cop spindle G is supported by a step bearing m fixed on the copping rail
I, and by a bearing formed in the bar 1, Fig. 1, also carried by the copping
rail; upon the cop spindle is fixed or formed the small pulley t, against the
side of which the friction cordo is led so as to cause sufficient friction to
obtain the requisite drag of the spindle as described in the Specification to
the before-mentioned Letters Patent. The cord o is fixed to the rail s carried
by the copping rail I, and after passing against tho pulley t is led over the
pulley upon the rod p, and is kept strained over the same by means of the
weight w. The pulley vis adjustablo upon the rod p, which is provided with a
screw thread upon its entire length, and which is carried in the manner shewn
by the bar 7- This bar is supported from the copping rail I by means of the
bell crank lever x, the fulcrum of which is fixed to the copping rail, and the
ends of the bar 2 work between guides y, y, also fixed to the copping rail.
The bar q, and with it the rod p and pullies v receive a reciprocating motion
in a similar manner to that imparted to the rod 6 described in the Specifica-
tion to the before-mentioned Letters Patent, by means of the lever and cam
J for the purpose of causing the pullies v to press the cords o, o, more or less
against the sides of the pullies t, and thus increasing or reducing the friction
and consequent drag according to the part of the cop upon which the winding
on is at the time taking place, or, in other words, according to the position of
the copping rail I. The pullies are made adjustable upon the rod p by
means of nuts screwed upon the latter, whereby it will be seen that the
friction of the pullies t against the cords o may be varied as required.
Having now described the nature of this Invention, and the manner in
which it is to be performed, what I claim is,-
First, the improved form of flyer herein-before described with reference to
the accompanying Drawing.

page_text: Second, the improved arrangement for supporting the cop spindles herein-
before described with reference to the accompanying Drawing.
Third, the improved arrangement for obtaining the variable drag of or
friction upon the cop spindles herein-before described with reference to the
accompanying Drawing.
In witness whereof, I, the said Charles Denton Abel, have hereunto set
my hand and seal, this Twenty-first day of July, in the year of our
Lord One thousand eight hundred and sixty-five.
CHARLES D. ABEL. (L.8.)
