I, URIAH SCOTT, of 15, Duke St., Adelphi, in the County of Middlesex,
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVED
METHOD OF CONSTRUCTING HOLLOW AND SOLID METALIC BODIES" to be as follows,
and to consist in the employment of sheet metal in the construction of any
description of article which requires a combination of strength & solidity for
the purpose for which it is required. To effect this object, I take any certain
quantity of sheet metal or metals, if the employment of more than one kind is
necessary or advantageous, according to the nature of the article to be manu-
factured, and having determined whether I shall roll it in a cold state or at a
red heat, I proceed in the following manner:-For the cold process, I lay my
sheet of metal or metals on a slab or table, and taking a mandril, rod, or other
suitable block of the size & shape required, I secure the extreme end of the
sheet, or outer sheet, if more than one is used, by the two cars or flaps left
on or attached for the purpose to the outside rims or edges of the said sheets
by nails, pegs, or otherwise; and during the said process of rolling, I employ
spelter or other suitable cementation between the surfaces of the various sheets

& under, or otherwise pressing the whole into as firm & compact a mass as
possible. I secure the whole of it by two or more rings or hoops, & submit it
altogether to the action of a heated furnace, & secure as much as possible
a gradual, equal, & simultaneous distribution of the required degree of heat
throught its entire substance; when it is withdrawn, & left to cool, the mandril
is removed, & the surface cleaned off, as necessary. If, on the other hand, it
is thought advisable to roll it in a hot state, I then expose the sheet or sheets
I am about to use to the action of a furnace, & drawing the same out as it is
required on a slab or table, I proceed as before, introducing in a similar manner
the spelter or other suitable cementation between the several surfaces. When
this mass is cool, it requires no further attention beyond the cleaning off, &c.
If instead of a hollow I require a solid body, I simply employ a very small
mandril, and on its removal fill up the vacant space with a corresponding
sized rod or not, as it is thought necessary. I by no means confine myself to
the employment or particular distribution of one or more metals, or even to the
employment of metals exclusively. I may use two or more sheets of various
metals, or metals with canvas, felt, or other suitable material in the same
body, or use one particular metal or other substance for the inner surface or
lining, & proceed with another kind of metal or other substance, using both or
all separately. All I claim is, the gradual construction & formation of any
body by the employment of sheets or layers of the required metal, with or
without other material, in preference to the usual methods at present known
& employed.
