page_text: form of all these boards can be varied so as to produce a boat of the desired model and
dimensions.
K-Fig. 1, are beckets or loops attached to the upper edge or gunwale of the boat,
which pass up through the mortices O, in the thwart-ship part, of the outriggers,
and through which keys L, are driven to hold these parts I, in place. The fore and
aft parts G, of the out-riggers are attached to the thwart-ship parts I, by passing the
ends of the latter through mortices M, in the former and they are held in place
by pins k.
Rowlocks may be attached either to the out-riggers or to the gunwale of the
boat.
If desired but one thwart-ship outrigger I, may be used-in this case it would be
placed amidships and the fore and aft parts G, would be attached to it in any suitable
manner.
The hinge or lashing X, by means of which I secure the several boards forming the
boat together, is made as follows:-
I pass the ends of a rope -Fig. 17-inward through the two holes d-c, in the
board B, and haul the rope through so as to bring its bight taut upon the outside of
the boat- then tie a knot Y, upon the inside of the boat-I then pass one end of
the rope out through hole c and lead it along to joint -up through this joint and to
hole e, in the other bottom board B,-through hole e and up through hole f-1 then
take the other end of the rope bring it to joint -down through this joint and to
hole e and up through this hole, and then haul all taut and tie knot Z on the inside
of boat.
In the drawings I have shown but one lashing which secures the lower edges of the
boards B together, but it will be understood that a lashing or hinge is also used to
secure the boards A and B together.
A great many different forms of lashings or hinges may be used to secure the
several edges of the boards together, and hence I do not desire to limit myself to any
particular form of lashing or hinge.
The canvas cover Q, is secured to the wooden boat. by a number of lashings R,
which are formed as shown in Fig. 17, by passing the two ends of the lashing through
two holes near the upper edge of the canvas cover Q, and also through two corre-
sponding holes in the upper edge of the boards A, then hauling taut and tying the
knot S, upon the inside of the boat.
The knots S can be slacked up a little when the boat is closed and hauled taut
again when the boat is expanded, so as to give the proper amount of tension to the
cover Q.
At the ends of the boat instead of the lashings R, a lashing may be carried across
the top of the boat from side to side of the canvas cover Q, or a triangular piece of
canvas may be sewed to the upper edges of the canvas cover Q, so as to form a deck
over the end of the boat.
The boards A and B may be of such form that the boards A may be turned
in to form the deck of the boat, as shown in Fig. 12, while the boards B form
the bottom.
When the boat is composed of three flexible boards as shown in Fig. 16, the ends of
the side boards A are lashed together and rests m of any suitable form are attached to
the lower edges of the side boards A, upon which the bottom board B may rest, and
straps or beckeis may be attached to each of the side boards A near their bottoms, of
such length that they will meet each other on top of the bottom B and by means of a
lever or heaver the beckets may be hove taut, so as to hold the bottom board firmly
in place.
j, is a
strip of canvas or other material fastened on lengthwise of the boat to the
canvas cover, and at or near the angles or joints, so as to prevent the cover from
becoming chafed.
The canvas cover may be treated with oil or any other suitable substance to render
it water-proof.

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. A folding boat the hull of which consists of two or more flexible boards hinged
together substantially as shown, and adapted when distended to bend and form a boat
the sides and bottom of which will be curved from end to end, in combination with a
water tight covering, and a thwart or prop for distending and keeping the boat open;
all substantially as shown and described.
2. The combination in a folding boat of two or more flexible boards of such form
that when hinged and distended as described, they will form a boat whose lines are
symmetrical curves length-wise of the boat, and furnished with rests secured near the
lower edges of two of said boards and extending inward for the bottom board to rest
upon, and the bottom board D, adapted to rest upon the said rests, and to be held in
place by straps or beckets as described, and a water proof cover Q, suitably secured to
said flexible boards, a thwart or prop to hold the boat open and devices for securing
said prop in place, all substantially as set forth.
3. The combination with a flexible boat of an out-rigger formed of the parts I,
extending across the boat, and the fore and aft parts G, said parts I, being
attached to the boat by the loops K, and keys L and, said fore and aft parts G,
being secured to said parts 1, by mortices and pins k, all substantially as shown and
described.
