I GEORG HEINZE of Klotziche near Dresden in the Kingdom of Saxony, Empire
of Germany Merchant 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:-
This invention relates to water velocipedes and the object thereof is to construct a
suitable velocipede of this nature for sporting purposes etc. The improved con-
struction is represented in the annexed sheet of drawings in which Fig. 1 is a
vertical longitudinal central section. Fig. 2 a plan and Fig. 3 a cross section of
the water velocipede hereinafter described, and of which the novel features are
pointed out in the claims.
The boat or floating structure of the velocipede consists of the two lateral tapered
cylinders A A placed parallel with each other and connected by the shorter portion or
dry well B sufficient to receive the seat and mechanism and sufficiently large to
support passengers or luggage in addition to the operator.
Behind the seat space B is the screw propeller S and the rudder R. The latter is
hinged to a block R' on a cross rod R2 fixed to the floats A A and its downwardly
projecting pintle R' terminates in a cross bar W, the ends of which are connected by
rods WW to a similar cross bar W2 on the spindle V which passes up into the
space B through a stuffing box V1 and terminates above in a hand-wheel H or a
tiller or other convenient steering device in convenient position in front of the
operator seated on the seat C. The shaft L carrying the screw propeller S of
suitable form is journalled in the aforesaid block R and passes through a stuffing
box L in the rear cross wall of the space B terminating in the part J¹ of the
In the front
frictional coupling by which it is connected with the operating gear.
part of the space B is journalled the crank shaft D having fly wheels D' and the
crank wrists of which are connected by links D to the ends of the two pedal
levers M M pivoted at a suitable position at their rear ends and having the foot
rests M M respectively so that the operator on seat C may alternately depress the
said pedal levers and cause the revolution of the shaft D. The latter carries also
the chain wheel E connected by chain with the chain wheel F on the shaft Q. On

page_text: the shaft Q slides a sleeve carrying the friction wheels J J and adapted to be moved
by the lever N in the known manner for bringing the one or other wheel J in
contact with the wheel J' on the propeller shaft, and consequently causing the
revolution of the latter in the one or other direction and forward or backward
propulsion of the velocipede.
The wheel J is made to slide upon the shaft L and the collar K on the former
engages the lever O, so that by corresponding movement of the lever O, the radial
distance of the wheel J' from the shaft Q may be enlarged or diminished and the
power and the speed of the vessel be consequently brought under greater command of
the operator.
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 what I
claim is
In water velocipedes.
1. The combination of the two parallel floats A A with the central dry well B
connecting said floats, a screw propeller behind the rear of said dry well and pedal
mechanism in said dry well for operating said screw propeller.
2. The combination of two lateral floats A A a central connecting dry well B,
a rudder behind the rear of said dry well a cross bar W below said rudder, a
spindle V passing through a stuffing box in the floor of said dry well, a cross bar W
on the lower end thereof and rods W₁ connecting said cross bars W W' for the
purpose set forth.
3. The combination with a propeller of a shaft carrying said propeller, a friction
wheel J' feathered to slide on said shaft, a cross shaft Q adapted to be driven by
power, a friction coupling J J feathered to slide on said cross shaft and to be moved
into peripheral engagement with said wheel J' whereby contact of said wheel and
coupling occurs at a desirable radial distance from said shaft Q for the purpose
set forth.
