PROVISIONAL SPECIFICATION.
Improvements in Pleasure Boats.
I, DAVID NEIL LENNOX, Arts Student, 47 Holmcroft Street, Greenock, do
hereby declare the nature of this invention to be as follows:-
This invention refers to improvements in the form and construction of small
sailing boats used for purposes of pleasure, and by which improvements I insure
stability on the part of the vessel in rough weather, and it may be described as
follows: It consists of two water and air-tight compartments, each of a boat-
shaped construction. These compartments, which I will hereafter refer to and
describe as the twin or double boat, are decked in the ordinary way and are shaped
at the prow in the form of a cutter or in such other form as may be found proper,
necessary, or useful. The beam of each is very narrow, so as to obviate as much
as possible the water resistance. Inside each of these twin or double boats I
provide the mechanism or machinery by which the boat is propelled. Each of
these twin or double boats is an exact duplicate of the other in every respect. I
connect them together by means of a series of cross beams so arranged as to provide
strength and rigidity with the smallest possible degree of weight. From suitable
points in the hull or inside keel of each I connect strong light rods proceeding
through the decks to a suitable distance above the decks, each rod being placed in
a slanting or diagonal form, and both sets of rods are connected at the top by
suitable cross rods, or in any other useful or proper method, so as to form the basis
of a seat. On the top of these rods at a suitable distance from the treadles after-
mentioned, I fix a seat on which the boat operator or boatsman will place himself
or be seated. Beneath his feet when he is seated I place a pair of treadles which
work in the usual alternate form, and these treadles when so wrought or moved,
actuate the propelling mechanism of the boat as aftermentioned. To these treadles
I attach suitable gearing which works in connection with a screw at the stern of
each of the twin boats, and thus the boats are propelled. On each of the boats I
provide a tiller which the operator can actuate or move from his seat in either
direction by the aid of cords. As a protection to the boatsman from the water
washing against the treadles and thus wetting his feet, I provide a suitable guard
above the level of the water, and under this guard the treadles are moved.

COMPLETE SPECIFICATION.
Improvements in Pleasure Boats.
I, DAVID NEIL LENNOX, of 47 Holmscroft Street, Greenock, North Britain,
Arts Student, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention refers to improvements in the form and construction of small
sailing boats used for purposes of pleasure, and by which improvements I ensure
stability on the part of the vessel in rough weather; and it may be described as
follows. It consists of two water and air-tight compartments, each of a boat-shaped
construction. These compartments, which I shall hereinafter refer to and describe
as the twin or double boats, are decked with canvas or in the ordinary way, and are

proper, necessary or useful. The beam of each is very narrow, so as to obviate
as much as possible the water, resistance.. Inside each of these twin or double
boats I provide the mechanism or machinery by which the boat is propelled. Each
of these twin or double boats is an exact duplicate of the other in every respect. I
connect them together by means of a series of cross beams so arranged as to provide
strength and rigidity with the smallest possible degree of weight. From suitable
points in the hull or inside keel of each I connect strong light rods proceeding
through the decks to a suitable distance above the decks, each rod being placed in
a slanting or diagonal form, and both sets of rods are connected at the top by
suitable cross rods, or in any other useful or proper method, so as to form the basis
of a seat. On the top of these rods at a suitable distance from the treadles after-
mentioned I fix a seat on which the boat operator or boatsman will place himself,
or be seated. Beneath his feet when he is seated I place a pair of treadles which
work in the usual alternate form, and these treadles when so wrought or moved
actuate the propelling mechanism of the boat as aftermentioned. To these treadles
I attach suitable gearing which works in connection with. a screw at the stern of
each of the twin boats, and thus the boats are propelled. I provide a tiller which
the operator can actuate or move from his seat in either direction by the aid of
cords.. As a protection to the boatsman from the water washing against the treadles
and thus wetting his feet I may provide a suitable guard above the level of the
water, and above this guard the treadles are moved.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings which I will now
proceed to describe.
Figure 1 is a part elevation and part section of one of the twin boats.
Figure 2 is a section of the boat taken athwartships.
Figure 3 is a plan with the covers or decks taken off.
AA are the twin or double boats, which may be shaped similar to an ordinary
boat, but with very narrow beams so as to have as little resistance to the water.
as possible. These twin boats AA are connected together by means of the
beams B, B1, B2, B'. Connected to the beams B2, B3 and rising in a slanting
direction are two rods C, C' which are connected together at the top by means of
a cross rod D or in any other convenient manner. At the top of these rods I fix
an ordinary bicycle seat E for the operator or boatsman to sit upon. Fixed to the
rod C is another rod Q, on which there is a handle R, for the operator to rest his
hands, on propelling the boat. Pivoted to this rod is another handle S, having
projections s, to each of which there is attached one end of the cords W for steering
the boat, the other ends being connected to the tillers U: the rudders. V being
connected together by means of a band or rod T. As the operator desires to steer
the boat in one direction or the other he pulls the handle S in the required
direction, which having one end of the cord attached to it, and the other to the
tiller, and the two rudders being connected together by means of the rod T, the
boat is easily steered without the operator having occasion to rise from his seat.
The intermediate shafts G of the treadle F are carried in the cross-bar Z, and
the outside treadle shafts G¹ are carried on bearings X fixed to the gunwale of
the twin boats. The treadles work in the usual alternate manner. Fixed to the
treadle shafts G' are the pinions H which gear into the toothed wheels I and
operate the shafts J. These shafts J have each at their opposite ends a large
toothed wheel K which gears into a pinion L and operates the shafts M with bevel
gearing N which again operates the propellor shafts O having a screw P at the end
of each, and so propels the boat.
In place of the gearing as described and shown I may have chain gearing for
operating the boat.
It is to be understood that with a little modification my improvements can be
adapted for tandem or more riders....

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Pleasure boats constructed substantially as described and shown on the accom-
panying sheet of drawings.
2. In pleasure boats, operating same by means of the feet, substantially as
described and shown on the accompanying sheet of drawings.
3. The arrangement for steering the boat substantially as described and shown
on the accompanying sheet of drawings.
