IMPROVEMENTS IN THE MANUFACTURE OF n Horzow DoDING CYLINDERS, TOBES, AND OTHER HOLLOW BODIES
Year: 1860

page_text: LETTERS PATENT to Joseph Henry Tuck, of Great George Street, West-
minster, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
n Horzow DoDING"
Scaled the 3rd August 1860, and dated the 22nd February 1860.
PROVISIONAL SPECIFICATION left by the said Joseph Henry Tuck
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd February 1860.
I, JOSEPH HENRY TUCK, of Great George Street, Westminster, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
CYLINDERS, TOBES, AND OTHER HOLLOW BODIES," to be as follows:-
This Invention has for its object improvements in the manufacture of
cylinders, tubes, and other hollow bodies, and consists in winding wood
shavings or thin cuttings of wood coated or saturated with suitable cementing
material traversely around a mandril or shape, preferring that the winding
should be inclined to the axis of such mandril or shape; one layer is wound
over the other until a sufficient thickness is obtained. When making cylinders
or pipes for underground work, it is preferred to employ bituminous cements,
though others may be used, and when making cylinders, pipes, or other hollow
bodies for other uses, other cements will be employed, depending on the
purposes to which such articles are intended to be applied. In some cases, in
addition to the use of wood shavings or thin cuttings of wood wound
transversely around the mandril or shape, layers of like materials are introduced
longitudinally, and are enclosed between the successive layers of the transversely

page_text: wound wood shavings or thin cuttings of wood, and in other cases strips of thin
sheet metal are introduced, and are spirally wound or are laid longitudinally
around the mandril or shape, and are enclosed between the succeeding transverse
layers of wood shavings or thin cuttings of wood; and further, in winding the
successive transverse layers of wood shavings or thin cuttings of wood around
the mandril or shape, the succeeding layers are preferred to be wound in
opposite directions.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Henry Tuck in the Great Seal Patent Office on the
22nd August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HENRY TUCK, of Great George Street, Westminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Henry Tuck, Her special licence that I, the said Joseph
Henry Tuck, my executors, administrators, and assigns, or such others as I,
the said Joseph Henry Tuck, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF CYLINDERS, TUBES, AND OTHER HOLLOW BODIES,"
upon the condition (amongst others) that I, the said Joseph Henry Tuck,
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 Joseph Henry Tuck, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of
cylinders, tubes, and other hollow bodies, and consists in winding wood shavings

page_text: or thin cuttings.of wood coated or saturated with suitable cementing material
transversely around a mandril or shape, preferring that the winding should be
inclined to the axis of such mandril or shape; one layer is wound over the other
until a sufficient thickness is obtained. When making cylinders or pipes for
underground work, it is preferred to employ bituminous cements, though others
may be used, and when making cylinders, pipes, or other hollow bodies for
other uses, other cements will be employed, depending on the purposes to
which such articles are intended to be applied. In some cases, in addition to
the use of wood shavings or thin cuttings of wood wound transversely around
the mandril or shape, layers of like materials are introduced longitudinally,
and are enclosed between the successive layers of the transversely wound wood
shavings or thin cuttings of wood; and in other cases strips of thin sheet metal
are introduced, and are spirally wound or are laid longitudinally around the
mandril or shape, and are enclosed between the succeeding transverse layers of
wood shavings or thin cuttings of wood; and further, in winding the successive
transverse layers of wood shavings or thin cuttings of wood around the
mandril or shape, the succceding layers are preferred to be wound in opposite
directions.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
I employ in each case a mandril or form of the internal diameter of the
hollow cylinder, tube, pipe, or other such hollow body, which mandril or form I
coat over with a coating of clay or whitewash or other matter to prevent the
cement coming in contact with the mandril or form used, and so that the
mandril or form may be readily drawn out when the tube, pipe, cylinder, or
hollow body has been formed thereon. It is not essential to use a mandril or
form in all cases, but I prefer to do so. The cementing materials used may be
of a bituminous or other character suitable for causing surfaces of wood to
adhere together, and of a waterproofing or other description, according to the
purposes to which the cylinders, tubes, pipes, or other hollow bodies are to be
applied. The cementing matters may be applied by brushes or otherwise to
the surfaces of the wood shavings or thin cuttings or strips of wood used, but
I prefer that the cement (kept in a fluid state) should be in a suitable trough
or vessel in such manner as to admit of the wood shavings being introduced
into the same, and to be drawn out progressively therefrom as the same are
wound round on the mandril or form, which I prefer to be mounted on axes
at its ends in order that it may be revolved; and I prefer that the wood
shavings or thin cuttings or strips of wood should be wound round in spiral
directions, and that the succeeding layers of wood shavings should be wound in

page_text: opposite directions till the desired thickness has been obtained. The cylinders,
tubes, and pipes thus produced may be rolled on or between plain surfaces
or between rollers by preference whilst on the mandrils or forms, so as more
closely to press the several layers together. In addition to the shavings or
thin cuttings of wood thus wound transversely around the mandril or form,
pieces of shavings or of thin wood or of other material may be placed longi-
tudinally round the mandril or form, and by preference between the layers of
shavings which are wound transversely around the mandril or form, and by
such means greater strength may be obtained.
In witness whereof, I, the said Joseph Henry Tuck, have hereunto set my
hand and seal, this Twenty-second day of August, in the year of
our Lord One thousand eight hundred and sixty.
