PROVISIONAL SPECIFICATION.
Water Cycle for Travelling on Water in similar Manner to Bicycling
on Roads.
EDWIN HARRY FRANCIS, Engineer 84, St. Johns Wood Terrace Regents Park
London do hereby declare the nature of this invention to be as follows:-
This applies to a machine for the purpose of travelling on water consisting of two
light metal floats, fixed parallel to each other by a movable deck or platform and
a series of stays by which the floats may be set wider or narrower for the purpose
of increasing or decreasing the stability of the machine as required. Each of the
two floats are composed of three airtight compartments marked c. c. c. on drawing.
The two end compartments of each float are rigidly held by four light steel stays so as
to admit the third and middle part which is fixed on centres and on the outer circum
ference of which is fixed a double archimedian screw.
The two middle compartments thus placed form buoyant propellers which are
rotated by a series of gearing and pedals. A saddle is fixed on the deck spaning the
two floats, the arrangement is such that one person propels and steers the machine, at
the same time faceing the direction in which the machine is traveling.
The machine may be made to carry one or any number of persons, and is unsink-
able and would carry as much weight bottom upwards as right side up.

COMPLETE SPECIFICATION.
Water Cycle for Travelling on Water in similar Manner to Bicycling
on Roads.
EDWIN HARRY FRANCIS Engineer 84 St. Johns Wood Terrace Regent Park
London 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 applies to a machine to be used for travelling on water for sporting, touring
and other purposes, consisting of two light metal floats fixed parrallel to each other
by a movable deck or platform and a series of light steel stays by which the floats
may be set wider or narrower for the purpose of adjusting the stability of the
machine on rough or smooth water as required.
Each of the two floats consist of three separate airtight compartments marked c. c. c.
on drawing filed with my provisional specification. The two end compartments of
each float are held rigidly in position by four steel longitudinal stays so as to
admit the third and middle part which being hung on centres and having double
archimedian screws on their outer circumference forms buoyant propellers. These
are rotated by a combination of gearing and pedals in a very similar manner to
an ordinary Tricycle. A saddle is fixed on deck spanning the two floats. The
arrangement is such that one person propels and steers the machine at the same
time facing the direction in which the machine is traveling.
The machine may be made to carry one or any number of persons, and is
unsinkable, and will carry as much weight when bottom upwards as when right
side up.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is in Water Cycles or Velocipedes
1-The combination of two parallel floats with the adjustable deck for the purpose
of setting floats any desired width as described.
2-The combination of two parallel floats consisting of six separate airtight
compartments, the two centre compartments forming buoyant propellers for the
purpose set forth.
3-The combination of parallel floats and central buoyant propellers with adjust-
able gear as arranged and shewn in drawing for the use and purposes as described.
Dated this 24th day of July 1889.
EDWIN HARRY FRANCIS.
