IMPROVEMENTS IN THE CONSTRATION OF PRINTING ROLLERS
Year: 1864

page_text: LETTERS PATENT to James Huntington, of Queen's Road Works, Hollow-
way, in the County of Middlesex, Surface Roller Maker, for the Invention
of "IMPROVEMENTS IN THE CONSTRATION OF PRINTING ROLLERS"
Sealed the 28th June 1864, and dated the 15th February 1864.
PROVISIONAL SPECIFICATION left by the said James Huntington at the
Office of the Commissioners of Patents, with his Petition, on the 15th
February 1864.
I, JAMES HUNTINGTON, of Queen's Road Works, Holloway, in the County
of Middlesex, Surface Roller Maker, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF PRINTING ROLLERS,"
to be as follows:-
The object of this Invention is to provide the wooden printing rollers used in
printing paper hangings with detachable spindles, whereby great economy of
space in stowage of the rollers, when not in use, will be effected, and also a con-
siderable saving in outlay for spindles. The disadvantages hitherto attendant
on the use of loose or detachable spindles have been that the rollers
having nothing to stiffen them when the spindles were removed, were liable
to warp, and that the means employed for wedging up the spindles when
applied to the rollers was liable to give an excentricity to the rollers. To
remedy these inconveniences I insert in the centre of the rollers a stout

page_text: tubular metal lining, and fix the same in position by means of suitable cement.
This metal lining or tube will so effectually stiffen the roller as to destroy its
tendency to warp. To facilitate the attachment of the spindle to the roller I
cone the ends of the tube in order that they may fit conical recesses made in
a loose clamping collar and flange on the spindle. The flange is forged on
the spindle, and a transverse projection is made in its conical cavity to fit a
notch made in one end of the tube. This is to prevent the spindle or the roller
receiving any independent axial motion. The coned collar fits onto the
opposite end of the tube, and it is held in place by a binding nut, which is
tapped to fit a screw thread cut on the spindle. By this arrangement not
only is the roller firmly secured on its spindle, but the concentricity of the
roller is effectually secured.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Huntington in the Great Seal Patent Office on the
15th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HUNTINGTON, of Queen's Road Works, Holloway, in the County of Middlesex,
Surface Roller Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth 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 James Huntington, Her special license that I, the said James
Huntington, my executors, administrators, and assigns, or such others as
I, the said James Huntington, 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 THE CONSTRUCTION OF PRINTING ROLLERS,"
upon the condition, amongst others, that I, the said James Huntington,
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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said James Huntington, 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, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):
The object of this Invention is to provide an efficient means of supplying
the wooden printing rollers used in printing paper hangings with detachable
spindles, the use of which affords a great economy of space in the stowage of
the rollers when not in use, and also effects a considerable saving in outlay for
spindles. The disadvantages hitherto attendent on the use of loose or detachable
spindles have been that the wooden rollers having nothing to stiffen them
when the spindles were removed were liable to warp, and that the means
employed for wedging up the spindles when applied to the rollers was liable to
give an excentricity to the rollers, either of which changes in the rollers was
fatal to their proper working. To remedy these inconveniences I employ the
arrangement shewn in various views in the accompanying Drawing, in which
Fig. 1 shews in side view a roller fitted according to my Invention; Fig. 2 is
a partial longitudinal section of the roller on an enlarged scale; Fig. 3 is an
end view of the roller, and Figures 4 and 5 are sections of the coupling for
securing the spindle to the roller.
A, A, is the roller made of any suitable wood and bored through the centre
to receive a stout tubular metal lining B. In its ends recesses a, a, are
formed as shewn at Fig. 2, and into these recesses the ends of the metal lining or
tube project. The tube B is fixed in position by means of liquid sulphur or
other suitable cement being run in between the roller and the tube. This
metal lining or tube B will so effectually stiffen the roller as entirely to destroy
its tendency to warp; C is the spindle which is formed with an enlargement
or abutting piece C' that is intended to bear against one end of the tube B,
and is also screwed to receive a nut D by which a loose sleeve or clamping
piece D', (shewn detached in side and end views at Figs. 6), is held in close
contact with the other end of the tube B.
To facilitate the attachment of the spindle C to the roller I cone the ends
of the tube B in order that they may fit the one a conical recess made in the
abutting piece C¹ of the spindle, and the other into the hollow cone of the
loose clamping piece D' applied to the spindle. The abutting piece C' I forge
on the spindle and provide a transverse projection or key c in its conical cavity,
which key fits into a notch 6 made in one end of the tube. By this means I
prevent the spindle or the roller receiving any independent axial motion which
would be prejudicial to the printing operation, the spindle C being inserted in

page_text: the roller, and the key c fitted into the notch b, the coned clamping piece D'
is applied to the opposite end of the tube B and the binding nut D being
screwed up tight on the spindle the roller will be firmly secured on its spindle
and the concentricity of the roller will be effectually secured.
Having now set forth the nature of my Invention of "Improvements in the
Construction of Printing Rollers," and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part recited
Letters Patent I claim, fitting printing rollers with detachable spindles in the
manner and for the purpose above described.
In witness whereof, I, the said James Huntington, have hereunto set
my hand and seal, the Fifteenth day of August, in the year of our
Lord One thousand eight hundred and sixty-four.
JAMES HUNTINGTON. (L.S.)
