Year: 1864

page_text: LETTERS PATENT to John Charles Dickinson, of Blackburn, in the
County of Lancaster, Machine maker, for the Invention of "IMPROVE-
MENTS IN THE DRYING CYLINDERS OF MACHINERY OR APPARATUS EMPLOYED FOR
SIZING AND DRYING YARN."
Sealed the 1st August 1864, and dated the 5th February 1864.
PROVISIONAL SPECIFICATION left by the said John Charles Dickinson
at the Office of the Commissioners of Patents, with his Petition, on the
5th February 1864.
I, JOHN CHARLES DICKINSON, of Blackburn, in the County of Lancaster,
Machine maker, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE DRYING CYLINDERS OF MACHINERY OR APPARATUS EMPLOYED FOR
SIZING AND DRYING YARN," to be as follows:-
This Invention has for its object a means or method of staying or
strengthening the ends of drying cylinders, preventing vibration, and obtaining
a true rotation for the said cylinders, which I effect as follows:-Inconstruct-
ing drying cylinders according to my Invention I employ a hollow cast-iron
shaft or pipe of the length of the drying cylinder required, and provided at
each end with a flange of suitable diameter, to the outer face of each
flange the plate forming each end of the cylinder is secured by bolts or other
means. Suitable buckets and pipes for the discharge of the condensed steam
are arranged, and the case or shell of the cylinder is fixed to the outer edges
of the end plates, as usual. By the use of the above-mentioned hollow shaft

from warping or bending of the plates forming the ends of the said cylinder
(by the pressure of steam), and a perfectly true axis around which the
cylinder rotates, thus securing the full advantage of the use of antifriction
rollers. Although I have above described the hollow shaft or pipe as cast
iron, the same may be made of any suitable metal or material and of any
length and diameter required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Charles Dickinson in the Great Seal Patent Office
on the 4th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CHARLES DICKINSON, of Blackburn, in the County of Lancaster, Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Charles Dickinson, Her special licence that I, the
said John Charles Dickinson, my executors, administrators, and assigns, or
such others as I, the said John Charles Dickinson, my executors, adminis-
trators, 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 THE DRYING CYLINDERS OF MACHINERY
OR APPARATUS EMPLOYED FOR SIZING AND DRYING YARN," upon the condition
(amongst others) that I, the said John Charles Dickinson, 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 John Charles Dickinson, 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 :-

page_text: This Invention has for its object a means or method of staying or
strengthening the ends of drying cylinders, preventing vibration, and obtaining
a true rotation for the said cylinders, which I effect as follows:-
In constructing drying cylinders according to my Invention I employ a
hollow cast-iron shaft or pipe of the length of the drying cylinder required,
and provided at each end with a flange of suitable diameter, to the outer face
of each flange the plate forming each end of the cylinder is secured by bolts
or other means, suitable buckets and pipes for the discharge of the condensed
steam are arranged, and the case or shell of the cylinder is fixed to the outer
edges of the end plates as usual. By the use of the above-mentioned hollow
shaft or pipe, and the flanges thereon, I obtain great strength of cylinder, a
freedom from warping or bending of the plates forming the ends of the
cylinder (by the pressure of steam), and a perfectly true axis, around which
the cylinder rotates, thus securing the full advantage of the use of anti-
friction rollers Although I have above described the hollow shaft or pipeas
cast iron, the same may be made of any suitable metal or material, and of any
length and diameter required.
In order more distinctly to illustrate my Invention I have hereunto
annexed a Sheet of Drawings illustrative thereof, and have marked the
same with figures and letters of reference corresponding with those in the
following explanation thereof, similar letters of reference being placed upon
corresponding parts of the apparatus in the various Figures.
Fig. 1 is an end elevation of a drying cylinder (shewing part of frame side
of machine); Fig. 2, a cross vertical section of the same shewing the arrange-
ment of buckets and pipes for the discharge of condensed steam; and Fig. 3
is a plan, partly in section, of one of my improved cylinders.
At A is shewn the hollow shaft or pipe, at each end of which is a flange B,
to which the plates 6 forming the ends of the cylinder are secured by bolts b¹;
C1, C2, C3, C4, are the buckets, and D1, D2, D3, D4, are the pipes for the
discharge of the condensed steam by way of the passage in the hollow shaft
or pipe A and the pipe a¹. It will be observed that the pipes D1, D2, D3, D4,
(Fig. 2), at or near their junction with the shaft A, are curved partly around
the said shaft, so that the water taken up by any of the buckets is delivered
in the hollow shaft or pipe A, and cannot return to the cylinder (see Fig. 2),
inwhich the buckets C1, C2,are shewn in position for the delivery of condensed
steam down their respective pipes D1, D2; at E are shewn antifriction pullies
on which the neck of the hollow shaft works.
Having thus fully described the nature and particulars of my said Invention
for "Improvements in the Drying Cylinders of Machinery or Apparatus

page_text: employed for Sizing and Drying Yarn," together with the manner in which
the same is to be or may be performed or carried into practical effect, I would
remark in conclusion that I claim as my Invention the construction of drying
cylinders in connection and combination with the peculiar arrangement of
buckets and pipes for the discharge of condensed steam, as herein set forth
and illustrated in the accompanying Drawings, or any mere modification of
the same.
In witness whereof, I, the said John Charles Dickinson, have hereunto
JOHN CHARLES DICKINSON. (L.S.)
Signed and sealed by the within-named
John Charles Dickinson in the
presence of
RICH. CHARLESWORTH,
Assist. Engineering Surveyor, &c.,
Blackburn.
