Year: 1884

page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN IMPROVED
AQUATIC VELOCIPEDE" a communication to me from abroad by Denis Telesplore
Simon of Paris, France to be as follows:-
This Invention relates to an improved aquatic velocipede or paddle boat propelled
by means of treadles connected with the paddle wheel crank shaft and steered by
means of a handle placed in front of the riders saddle the boat being propelled and
steered by one person like an ordinary velocipede.
The accompanying drawing shows the stern end of a boat provided with the
improved propelling and steering mechanism of this Invention, figure 1 being a
sectional elevation and figure 2 a plan thereof.
A is the hull of the boat constructed in any suitable manner, a'a are bearing
blocks mounted on the gunwales to receive the crank shaft b, b, of the paddle.

There may be four or more cranks upon the paddle shaft and a corresponding
number of treadles and seats for propelling by more than one person the size of the

page_text: 1, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN IMPROVED
AQUATIC VELOCIPEDE" (a communication to me from abroad by Denis Telesphore
Simon of Paris, France,) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
This Invention relates to an improved aquatic velocipede or paddle boat propelled
by means of treadles connected with the paddle wheel crank shaft and steered by
means of a handle placed in front of the rider's saddle, the boat being propelled and
steered by one person like an ordinary velocipede.
The accompanying drawing shows the stern end of a boat provided with the
improved propelling and steering mechanism of this Invention, figure 1 being a
sectional elevation and figure 2 a plan thereof.
A is the hull of the boat constructed in any suitable manner, a a are bearing
blocks mounted on the gunwales to receive the crank shaft bb, of the paddle wheels,
whose blades c c, may either be fixed to the arms d or be made to feather.
The shaft b, has two cranks, e e, at right angles to each other, or at any other
____angle, which_are connected by rods ff. to the forward ends of two treadles g g
pivoted at h h to the bottom of the boat. i is a saddle for the person to sit on
when propelling the boat. jj are two fly wheels for equalizing the revolutions of
the paddle wheel shaft. is the steering spindle mounted to turn in a footstep and
in the front part of the seat i and provided with a cross handle l. Upon the spindle
is also fixed a pair of arms m connected by rods n to the yoke o mounted on the
head P of the rudder .. The yoke rods n may be replaced by cords, but rods are
employed by preference, as they both act together upon the rudder by a combined
pulling and thrusting action. The yoke rods or lines n n are enclosed by a casing s.
t are the paddle boxes.
There may be four or more cranks upon the paddle shaft and a corresponding
number of treadles and seats for propelling by more than one person, the size of the
boat being correspondingly increased.
Each crank e of the propelling shaft may have a second shorter rod connected
with it to be operated simultaneously with the rods f by means of hand levers
placed within reach of the person working the treadles whereby to assist in the
propulsion of the velocipede.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
In a propeller for boats, the arrangement and combination of the treadles y
connecting rods fand crank shaft b, c, with the saddle i and steering spindle / of
rudder r, whether cranks e be provided or not with hand levers in combination with
the treadles as described.
