Year: 1861

page_text: LETTERS PATENT to Charles William Lancaster, of New Bond Street, in
the County of Middlesex, Gun Manufacturer, for the Invention of "AN
IMPROVED METHOD OF SHEATHING SHIPS AND VESSELS WITH COPPER AND OTHER
METALLIC SHEATHING."
Sealed the 3rd December 1861, and dated the 7th June 1861.
PROVISIONAL SPECIFICATION left by the said Charles William Lancaster
at the Office of the Commissioners of Patents, with his Petition, on tho
7th June 1861.
I, CHARLES WILLIAM LANCASTER, of New Bond Street, in the County of
Middlesex, Gun Manufacturer, do hereby declare the nature of the said
Invention for "AN IMPROVED METHOD OF SHEATHING SHIPS AND VESSELS WITH
COPPER AND OTHER METALLIC SHEATHING," to be as follows:-
My Invention is intended chiefly to apply to iron ships and vessels, though
it may be used for wooden ships and vessels. My Invention consists in
coating the parts to be sheathed with bitumen, asphalte, or other like bitu-
menous composition, or cement or composition herein-after named, and in
covering the inside of the copper or other metallic sheathing with a similar
coating, in placing the coated side of the sheathing on the bitumenous coating
on the ship or vessel, and in the application of heat to the copper, whereby
the bitumen or bitumenous composition becomes adhesive, and cements the
sheathing to the ship or vessel. I prefer, before applying the coating to the
ship, when of iron, to screw in studs which project to any required extent.
[

page_text: make corresponding holes in the copper or other sheathing, which pass over the
studs; I then, by preference, apply a washer over the heads of the studs, and
beat them out to convert them into rivets. The washers may be dispensed
with, and other modes of fastening by screws or bolts may be adopted in com-
bination with my bitumenous cement. In the case of wooden ships and vessels,
nails may be used as at present.
I have stated my Invention to consist in coating the ship or vessel and tho
inside of the sheathing with bitumen or bitumenous composition, and I have
done so, as I find the best results obtained thereby; but I reserve to myself
the right to employ any cement or composition which will become adhesive
and adhere to metal, or metal and wood, on being heated or dissolved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles William Lancaster in the Great Seal Patent Office
on the 7th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
WILLIAM LANCASTER, of New Bond Street, in the County of Middlesex, Gun
