THE IMPROVEMENT IN THE CONSTRUCTION OF NAVIGABLE VESSELS, AND IN THE METHOD OF PROPELLING AND STEERING THE SAME
Year: 1881

page_text: LETTERS PATENT to James Frazer Jaquess, of 33, Chancery Lane, within the
Liberty of the Rolls, London, for an Invention of "THE IMPROVEMENT IN
THE CONSTRUCTION OF NAVIGABLE VESSELS, AND IN THE METHOD OF
PROPELLING AND STEERING THE SAME." A communication from abroad
by the late William Atwood, of Troy, State of New York, United States
of America.
PROVISIONAL SPECIFICATION left by the said James Frazer Jaquess at the
Office of the Commissioners of Patents on the 27th May 1881.

London. "THE IMPROVEMENT IN THE CONSTRUCTION OF NAVIGABLE VESSELS,
AND THE METHOD OF PROPELLING AND STEERING THE SAME." (A communication
from abroad by the late William Atwood, of Troy, State of New York, in the
United States of America.)
The object of the Invention is to construct a vessel of sufficient beam to carry
one or more propellers laterally in the centre of the vessel & beneath the water
line.
I construct a vessel with great width or beam bevelling off in a curved line
towards the keel at an angle of about forty-five degrees, the vessel being constructed
in such manner as to be navigable without carrying ballast.
By these means I secure greater carrying power, stability, & room for placing
the engines.
To provide for the propelling of the vessel it is furnished with a screw propeller,
and according to the size of the vessel I employ two or more propellers, using
suitable mechanism for working the same, the propeller being so placed as to work
beneath the water line by means of suitable mechanism.
In thus constructing the vessel and placing the locomotive power close to the
propeller in the side instead of the stern of vessel I attain great stability, a high
rate of speed, & reduce the consumption of fuel, and increase the power of steering
the vessel.

The object of this Invention is to construct a vessel of sufficient beam to carry
one or more propellers laterally in the centre of the vessel and beneath the water
line.
I construct a vessel with great width or beam bevelling off in a curved line
towards the keel at an angle of 45°, the vessel being constructed in such manner as
to be navigable without carrying ballast.
By these means I secure greater carrying power, stability, and room for placing
the engines. To provide for the propelling of the vessel it is furnished with a
screw propeller on each side, and according to the size of the vessel I employ two
or more propellers, using suitable mechanism for working the same, the propeller
being so placed as to work beneath the water line by means of suitable mechanism.
In thus constructing the vessel and placing the locomotive power close to the
propeller in the side instead of the stern of the vessel, I attain greater stability, a
high rate of speed, and reduce the consumption of fuel, and increase the power of
steering the vessel.
When used as a life boat on board ships, it is constructed after the same pattern
or model with the addition of water tight compartments at each end of the boat,
for reception and protection of the passengers, with capacity for carrying water and
provisions sufficient for all on board for any reasonable length of time, and is so
arranged as to be propelled by oars. As a life boat it is valuable from the fact of
its being
1. Self righting.
Fig. 1 is an end elevation shewing the propellers a, a.
Fig. 2 is a side elevation. Inside the cases or boxes b, b, are fixed the propeller
shafts.
Fig. 3 is a plan.
Fig. 4 is an end elevation, and
Fig. 5, a plan of my lifeboat.
In witness whereof, I, the said James Frazer Jaquess, have hereunto set my hand
and seal, this Seventeenth day of December, in the year of our Lord One
thousand eight hundred and eighty one.
