Year: 1859

page_text: LETTERS PATENT to William Haggett, of Sherborne, in the County of
Dorset, Architect and Surveyor, for the Invention of "AN IMPROVED
METHOD OF TREATING METALS AND OTHER MATERIALS TO INCREASE THEIR
STRENGTH."
Sealed the 15th September 1859, and dated the 21st March 1859.
PROVISIONAL SPECIFICATION left by the said William Haggett at the
Office of the Commissioners of Patents, with his Petition, on the 21st
.March 1859.
I, WILLIAM HAGGETT, of Sherborne, in the County of Dorset, Architect
and Surveyor, do hereby declare the nature of the said Invention for "Ax
IMPROVED METHOD OF TREATING METALS AND OTHER MATERIALS TO INCREASE THEIR
STRENGTH," to be as follows:-
:
This Invention consists in-giving to iron and other metals, by rolling, press-
ing, or casting, an undulated surface, composed of longitudinal and transverse
corrugations crossing each other at right angles, or diagonally at such other
angles as may be most advantageous for the purpose to which the prepared
article is to be applied; and also in givinga similar surface to wood, cardboard,
papier machee, and all other materials capable of being pressed and moulded;
whereby an ornamental surface is produced, and the strength of all such
metals and other materials is increased, rendering them more suitable for
many architectural and mechanical purposes.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Haggett in the Great Seal Patent Office on the
20th September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HAGGETT, of Shorborne, in the County of Dorset, Architect and Surveyor,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Haggett, Her special licence that 1, the said William
Haggett, my executors, adininistrators, and assigns, or such others as I, the
said William Haggett, 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 "AN IMPROVED
METHOD OF TREATING METALS AND OTHER MATERIALS TO INCREASE THEIR STRENGTH,"
upon the condition (amongst others) that I, the said William Haggett, 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 per-
formed, 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 William Haggett, do hereby declare
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, that. is to say :-
This Invention consists in giving to iron and other metals. by rolling,
pressing, or casting, an undulated surface, composed of longitudinal and
transverse corrugations, crossing each other at right angles, or diagonally
at such other angles as may be most advantageous for the purpose to which
the prepared article is to be applied; and also in giving a similar surface to
wood, cardboard, papier mâchee, and all other materials capable of being
pressed and moulded, whereby an ornamental surface is produced, and the
strength of all such metals and other materials is increased, rendering
them more suitable for many architectural and mechanical purposes.

page_text: And in order that the manner of performing this my Invention may be
more fully understood, reference is had to the aunexed Drawings, and to
the following description of the same :-
Figure 1 is a plan view, and Figure 2 a section ou the line a, b, of a
sheet of metal or other material, to which an undulating or longitudinal
and transversely corrugated surface has been given by means of pressing,
rolling, or casting, whereby an ornamental surface is produced, and the
strength of the material increased. Figure 3 is a plan view of a -sheet of
metal or other material, in which the corrugations, instead of crossing each
other at right angles, are arranged diagonally. The particular arrangement,
as well as the size and depth of the corrugations, may be varied according
to the nature of the material acted upon, its dimensions, and the purpose
for which it is intended to be employed. The corrugations may be produced
by pressure between dies or rollers, or by moulding and casting. Figure 4
is a longitudinal view, and Figure 5 an end section, of an iron or other
metal bar corrugated longitudinally, and at-right angles on each of its four
faces; and the corrugations, either at right angles or diagonally, may be
applied to all the faces, or to the upper and under oues only, by passing
the bar between suitably engraved rollers or dies, as aforesaid. The surface
of round bars may also be similarly treated. Figure 6 shows a brick, corru-
gated crosswise on the upper and under surfaces, by moulling the clay in
suitably formed moulds or dies, which bricks mutually interlocking, either
longitudinally or transversely with each other, will give greatly increased
strength in bonding, and will prove especially valuable in the construction
of sea walls, tanks, and other structures exposed to great lateral pressure,
and liable to displacement; wood bricks, similarly corrugated, may be pro-
duced by planing, moulding, or pressing, which will interlock with the
forner, and cannot be withdrawn from their places when once fixed. Tiles
may also be corrugated crosswise or diagonally by moulding in suitable dies
or inoulds. Tubular and other beams and girders,of any length and strengih,
for building, railway, and other purposes; may be forined of two or more
plates of iron corrugated as herein-before described; or girders may be
constructed of two or more corrugated plates of iron, bolted together with
timber, corrugated to match, interposed-between them; or a single plate of
corrugated iron may be placed between two beams of wood, the inner surfaces
of which have been corrugated to match. In all these cases the interlocking of
the corresponding surfaces mutually support each other throughout, increas
ing the strength thereof, and of the structures to which they are applied.
This improved method of incrousing their strength is applicable to all

page_text: metals, wood, cardboard, paper mâchec, clay, and all other materials capable
of being rolled, pressed, cast, or moulded; and the materials so strengthened
are applicable, either separately or in combination, to a great variety of
purposes, amongst others to suspension, tubular, swivel, swing, and other
bridges, ship and boat building and sheathing, railway and tramroad works,
canal locks and aqueducts, railway and other carriages and engines, steam
and other boilers, hydraulic and other works, tanks, cisterns, pipes, chain
cables, and other chains, iron and other houses, joists, girders, roofs, metal
and other slates, furnaces, boilers, and every description of domestic and other
utensils usually made of metal, and all other erections and works composed
of metal, and other materials, affording facility for expansion and contraction,
and securing the greatest strength either separately or in combination.
I am aware that single corrugated surfaces have been heretofore given
to metal and some other materials, to increase their strength in one direction,
I do not therefore claim. the single corrugation of surfaces for this purpose.
What I claim as new and constituting my Invention of an improved method
of treating metals and other materials to increase their strength, is the double
or cross corrugation of the surfaces at right angles, or diagonally at any other
angle, of the various metals and materials herein-before enumerated, and all
other metals and materials to which the said process is applicable, by
pressing, rolling, moulding, or casting.
And I claim the application of materials so corrugated and strengthened
to all the purposes herein-before mentioned, and all other purposes for
which they can be usefully employed.
In wituess whereof, I, the said William Haggett, have hereunto set
my hand and seal, this Seventeenth day of September, in the year of
our Lord One thousand eight hundred and fifty-nine.
