IMPROVE- MENTS IN THROSTLE SPINNING AND DOUBLING MACHINES
Year: 1862

page_text: LETTERS PATENT to Eli Dyson, of Little Hulton, near Bolton, in the
County of Lancaster, Cotton Spinner, for the Invention of "IMPROVE-
MENTS IN THROSTLE SPINNING AND DOUBLING MACHINES."
Sealed the 27th February 1868, and dated the 3rd September 1862.
PROVISIONAL SPECIFICATION left by the said Eli Dyson at the Office
of the Commissioners of Patents, with bis Petition, on the 3rd Sep-
tember 1862.
I, ELI DYSON, of Little Hulton, near Bolton, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THROSTLE SPINNING AND DOUBLING MACHINES," to be as
follows:-
My Invention relates to spinning and doubling machines of the character
of the "throstle," and to such machines as have a moveable spindle rail,
which also acts as the "copping rail." Hitherto, in such throstle spinning
and doubling frames the moveable spindle and copping rails have been.
separate and independent of each other, and by the pull of the bands driving
the spindles, the moveable copping rails have been forced entirely to one side,
causing considerable friction upon the slides, and unsteady and irregular
motion.
My Invention consists in connecting the moveable spindle rails on each
side together by brackets secured to the rails, by which means the pull of the
bands or force acting upon the spindle rails on one side of the frame is counter-

page_text: balanced by that acting upon the spindle rails on the other side of the
frame, and thus the friction upon the slides is obviated, and the moveable
spindle rails are kept true, steady, & free from irregularities in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Eli Dyson in the Great Seal Patent Office on the 27th
February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELI
DYSON, of Little Hulton, near Bolton, in the County of Lancaster, Cotton
Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of September, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Eli Dyson, Her special license that I, the said Eli Dyson,
my executors, administrators, and assigns, or such others as I, the said
Eli Dyson, 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, exercise, 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 AND DOUBLING MACHINES," upon the condition (amongst others) that
I, the said Eli Dyson, by an instrument in writing under my hand and seal,
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 Eli Dyson, do hereby declare the
nature of my 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) :-
:-
My Invention relates to spinning and doubling machines of the character
of the throstle, and to such machines as have a moveable spindle rail, which
also acts as the copping rail. Hitherto, in such throstle spinning and
doubling frames the moveable spindle and copping rails have been separate
and independent of each other, and by the pull of the bands driving the
spindles the moveable copping rails have been forced entirely to one side,

page_text: causing considerable friction upon the slides, and unsteady and irregular
motion.
My Invention consists in connecting the moveable spindle rails on each
side together by a bar or by brackets secured to the rails, by which means
the pull of the bands or force acting upon the spindle rails on one side of the
frame will be counterbalanced by that acting upon the spindle rails on the
other side of the frame, and thus friction upon the slides is obviated, and
the moveable spindle rails are kept true, steady, and free from irregularities in
motion.
Fig. 1 is a cross sectional elevation of so much of a throstle frame as will
be necessary for the purpose of explaining my Invention, and Fig. 2 is a
similar view to Fig. 1 of another modification of my Invention.
A, framing; a, tin drum driving spindles; b, foot step spindle rails; c, inoveable
spindle and copping rails; d, spindles (shewn only on one side of Fig. 1 ;)
e, shafts for giving the up-and-down motion to the moveable spindle rails
acting through the pulleys, chains, or straps upon the lifting rods f in the
ordinary manner; 9, balance weights. The above described parts are ordinary
and well known.
My Invention consists in connecting the two rails c by a bar h passing at
suitable intervals (say at every cross frame or spring piece) from one rail to
the other, as shewn in Fig. 1.; these bars or brackets (h) have pro-
jections (h) at the side which fit and slide against the ledges on the cross
frames (A) so that side oscillation is prevented. In Fig. 2 the cross bar or
bracket (h) is modified, so that I am enabled to dispense with one of the
shafts (e) for lifting the copping rail and also the lifting rods (f) by applying
a forked addition (h*) to each of the brackets (h), which is made to descend
in the middle of the frame to a suitable guide (h) bolted to the framing; the
lower end of the forked part (h*) slides up and down in the guide, and is
kept in the guide (h) by the head of a bolt (h³), which passes through a slit
in the guide (h). The fork part (h*) is arranged so that it can be detached
from the cross bar (h) when the tin drum (a) has to be removed. The fork
part (*) and cross bar (h) may be made all in one piece, but open at the
top (as shown by dotted line) so that the tin roller (a) can be removed by
leaving a gap in the cross frames, which could be closed by a bar forming a
"fish joint," and thus by removing the creel board the tin drum could be
removed when required without disturbing the cross bar (h) and fork
part (h*).
I have now particularly described the nature of my Invention, and the mode
of carrying the same into effect, and claim as my Invention,—

page_text: Firstly, the connecting of the two moveable spindle and copping rails (c),
substantially as herein-before described.
And, secondly, the connection and mode of actuating the two moveable
spindle and copping rails (c) by one shaft (e), substantially as herein-before
described and shown in Fig. 2 of the accompanying Drawings.
In witness whereof, I, the said Eli Dyson, have hereunto set my
hand and seal, this Twenty-fourth day of February, in the year of our
Lord One thousand eight hundred and sixty-three.
