PROVISIONAL SPECIFICATION.
A Corkwood Paddle Raft.
I, SAMUEL IRVINE, Cork Manufacturer, of 33 Brown Square in the City of
Belfast and County of Antrim in Ireland do hereby declare the nature of this
invention to be as follows:-
This raft consists of two cylinders each composed of pieces of corkwood pegged
together with wood in ten sections of two feet long by one foot nine inches in
diameter making a total length of twenty feet to each cylinder.
The end sections are conical shaped tapring to a diameter of six inches. Each
cylinder is covered with painted canvas and throughout its entire length runs a
mallable iron tube. These cylinders compose the sides of the raft and are joined
together on each side by planks seven feet long by six inches broad and one and
a half inches thick which are laid on three inch planks resting on and running the
entire length of each cylinder the whole being fastened by tie rods which pass
round and rise at the end of each section from the mallable iron tube which runs
through the centre of the corkwood. Over this is placed longitudinal bars of
wood two inches broad by one inch thick and one and a half inches apart forming
a grating deck on each side of the raft the dimensions of which are twenty one
feet by seven feet. These decks are supported in the interior by iron bars passing
from one to the other of the cross beams.
In the centre of the raft between the two decks there is a paddle wheel revolving
on a shaft supported by the corkwood cylinders and propelled, when necessary, by
a handle which can be raised through a trap door in the upper deck.
The raft is steered by an ordinary rudder while in the forward part a place
is made for the reception of a mast; also along the outer edge of the deck are
bored holes for rowlock pins.

a total length of 20 ft. to each cylinder. The end sections are conical-shaped,
tapering to a diameter of 6 in. Each cylinder is covered with painted canvas,
and throughout its entire length runs a malleable iron tube. The cylinders compose
the sides of the raft, and are joined together on each side by planks 7 ft. long

running the entire length of each cylinder, the whole being fastened by tie-rods,
which pass round and arise at the end of each section from the malleable iron tube

bars of wood 2 in. broad by 1 in. thick and 1 in. apart, forming a grating deck on
each side of the raft, the dimensions of which are 21 ft. by 7 ft. On the edge of
each deck is placed a plank 6 in. broad and 14 in. thick through which are iron pins
