911 H E present Manufacturers, (who have recently purchased
the Patent of this valuable concern,) in re-offering the
IMPROVED PATENT SHEATHING FELT to the no-
tice of Ship Owners, Ship Builders, Railroad Companies,
Builders, and others. deem it unnecessary to say anything with
regard to the importance.of such a material, as its characteriand -
uses are now so well appreciated, particularly by Ship Builders,
that scarcely any ship proceeds to sea without it; and.when it
is stated, that the Improved Patent Felt now offered dues not
greatly exceed the expence of tarred brown paper, it may. be
'confidently expected that it will supersede the use of every ma-
terial for a like purpose now employed for sheathing Ships'
bilt•to m s.
The Patent Sheathing Felt now submitted is made of a much
'stronger and more fibrous texture. than the Felt hitherto in use,
and will hear much greater extension under water in the work-
ing and straining of a Ship; and, added to its valuable proper-
ties for resisting the worm, its compressed closeness and tough-
ness of fabric, combined with its evenness and uniformity of
surface, entirely remove the objections inseparable from the
Felts hitherto in use, owing to the thickness, inequality, and
sponginess of their material, by which a quilting or puckering
is produced, very detrimental to the nailing and even-wearing
of.tbe copper, to say nothing of the risk of the nails drawing,
froM the expansion of the old Felts whenfiaturated with water.
The Felt now offered being entirely free from these serious ob-
jections, and the copper dressing on it so much better than on
any other, a greater degree of durability and safety to the cop-
per sheathing itself, may, by its use, be reasonably inferred. It
likewise possesses the advantage of being easily separated after
being packed or laid together for any length of time, which is
an important consideration in shipping it to hot climates.
The price is now reduced to about one-fourth of the cost of
the old hand-made Felt, and to less than half the price of the.
Felts now in use. It is manufactured in similar sized sheets to
those (32 inches wide by 20 inches long, and sold at FOUR
PENCE PER SHEET. It is also cut into sheets of double
and treble the above length, but it can likewise be delivered in
a continuous roll of any extent, at the above proportionate cost,
and afterwards' cut into any lengths required, by which means
the number of joints in laying it on, can be diminished at dis-
cretion, offering an immense increase of security wherever,_the
copper may be rubbed off.
A second description of a much thicker quality, adapted for
use under Wood Sheathing, is also matinfaCtured in any lengths
required
For Baling and Wrapping, the present Felt is impervious to
wet, and much cheaper than Tarpaulin. For Roofing, Out-
buildings, Sheds, &c. it excels either Sheathing or Roofing
Paper, being far more durable, and not liable to crack with the
changes of temperature.
