Improvements in Hand Power Apparatus for Propelling Buoys,
Boats, and the like.
1, EDWARD ADAMS SLADE of Challoner Grove South Shields, in the County of
Durham Marine Engineer do hereby declare the nature of this invention to be as
follows:-
This my invention consists in the application of the screw propeller or paddle
wheel fixed to such shafts or machinery as can be readily made to revolve by
turning a handle or treading a crank, to propel or move tubular boats, closed buoys,
or tubula life saving rafts of such construction as have hitherto only been driven by
sails, oars, hand paddles, steam, or stored forces. These tubular vessels or buoys I
intend to manufacture of galvanized iron sheets or other thin substance, formed into
cylindrical or cigar shaped pontoons or buoys.
The drawings now lodged with this Provisional Specification are descriptive of
my invention.
A represents a tubular buoy which forms part of the hull of such craft.
B the rudder.
Ca cord leading from the rudder head D, to a yoke or lever near fore end
marked E, for steering with the feet in craft of this design.
Fa pillar upon which the yoke E is pivotted.
Ga drum or sheave which carries a belt, cat-gut, rope, or chain, for transmitting
power exerted by the rider to the propeller shaft, and thence to the screw
propeller.

I EDWARD ADAMS SLADE of Challoner Grove South Shields in the County of
Durham Marine Engineer, 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 my invention consists in the application of the screw propeller or paddle
wheel fixed to such shafts or machinery as can readily be made to revolve by
turning a handle or treading a crank to propel or move tubular boats, closed buoys,
or tubular rafts, of such construction as have hitherto only been driven by use of
sails, oars, hand paddles, steam, or stored forces. These tubular vessels or buoys
intend to manufacture of galvanized iron sheets or other thin substance, formed into
cylindrical or cigar shaped tubes or buoys.
The drawings lodged with Provisional Specification are descriptive of this my
invention.
A. represents a tubular buoy which forms part of the hull of such craft.
B. the rudder.
C. a cord leading from the rudder head D. to a yoke or lever near fore end
marked E. for steering with the feet, in craft of this design.
F. a pillar upon which the yoke E. is pivotted.
G. a drum or sheave which carries a belt, cat-gut or chain, for transmitting power
exerted by the rider to the propeller shaft and thence to the propeller.
H. propeller shaft.
I. universal joint by which the aft length of propeller shaft is connected to the
fore length of propeller shaft.
J. thrust bearing.
K. stern bearing.
L. propeller.
M. a roller or drum fixed on propeller shaft and partly encircled by the driving
belt.
N. supports for the drum G.
O. supports and bearings for propeller shaft.
P. back of seat for rider.
Q. deck or platform.
R. hinge of rudder.
S. rod coupling rudder to other rudder when two or more tubes are used to form
one craft.
T. driving belt.
U. crank handles for turning main drum.
By turning the handles U. the machinery is caused to revolve and thereby the
craft is propelled or moved along.
By placing the feet against the yoke E. and moving one foot forward whilst the
other is drawn backward, the rudders may be moved to any desirable position and
thereby the craft is steered.
Boats constructed in accordance with this my invention possess the following
advantages.
They may safely be used by persons who never have rowed or managed a boat
of other description.
They will not fill with water or sink if capsized.
They are comparatively of less weight and bulk than the ordinary open boat,
and therefore more conveniently portable.
The machinery is simple and unlikely to get out of order.
The exertion required to cause them to travel is more constant and less laborious
than rowing.

page_text: The rider faces towards the course he intends to steer instead of travelling
backwards, therefore he can more easily avoid collisions or running aground.
Such craft can be used in narrow streams or creeks where there is not sufficient
room to row with oars.
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;-
1. The application of machinery made to revolve by hand to the propulsion or
the driving along of tubular boats, closed buoys, or tubular rafts.
2. The application of universal joints in shafts, to the propulsion or driving along
of tubular or closed buoy crafts that are caused to move through the water by
manual exertion.
3. The application of yokes or levers that receive motion from the feet of the
rider, whilst the rider steers by the feet and causes machinery to revolve by his
hands on tubular boats, closed buoys or tubular rafts.
