Improvements in and relating to Oars.
JOHN SMITH HAINSWORTH 19ª Coleman Street London E.C. Colonial Agent
do hereby declare the nature of this invention to be as follows:-
A method of and apparatus for propelling a boat in the same direction as
the person faces who is rowing the boat.
The invention has for its object the increased pleasure of being able to see
where the boat is travelling & also the avoidance of danger by seeing any
obstacle there may be in the way.
For the purpose of my invention I have a moveable bar of some strong material
or substance attached to the side of the boat on which a set of levers (with or
without wheels) work, by means of which the action of the sculls is from bow to
stern while in the water, as is usual, but the operator sits facing the bows &
rows in exactly the same manner as at present.

The our consists of two sections, connected by cross piece, each section is elbow
shaped, the one held by the rower, termed the handle section is attached to a
revolving bar to permit of its being raised or dipped, this bar is fixed to an outrig
at one end and the gunwale on the other end. The "blade" section of the oar
is also attached to this revolving bar by an upright pin, the two sections are
secured to each other by cross piece, the blade section will either row backwards
or forwards at the wish of the rower, and is fixable either forward or aft of the
handle section as may be desired.
The blade on the oar is also an improvement being bevelled towards the stern on
the whole length and upper part of the blade, the lower part being cut straight
and sharp and the idea is to cut the water better downwards whilst the bevelled
edge assists propulsion it has a lifting tendency which has not hitherto been
obtained. The whole or part of the oar is so geared as to be detachable instantly.
The iron work for bar and outrigger is made of tubing to secure lightness with
strength of parts.

JOHN SMITH HAINSWORTH 19 Coleman Street London E.C. Colonial
Agent 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 :-
The oar consists of two sections, connected by a cross piece, each section is
elbow shape, or either may be straight, the one held by the rower, termed the
handle section, is attached to a revolving bar, to permit of its being raised or
dipped. This bar is fixed to an outrig at one end, and the gunwale at the other
end. The blade section of the oar is also attached to this revolving bar by an

blade section will either row backwards or forwards at the will of the rower.
The whole or part of the oar is so geared as to be detachable instantly.
For better appreciation of the invention I annex a plan of the parts.
Fig. 1. The blade section A is fitted by upright pin B. and made to swivel,
to bar C. and connected by crosspiece D. at point L. to handle section E. at
point M.
Handle section E. is fitted by upright pin F. and made to swivel, to other
end of bar C. Bar C. is attached to outrig G. by swivel pin J. at one end and
gunwale H. by swivel pin N at the other end. Outrig G is fixed to gunwale H
at points K. K. K.
The operator moving E. works A. backward and forward E and A. being fixed
to revolving bar C. can be raised or dipped at will.
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 that which I
claim is viz.
A divided oar, being sections A and E. connected by crosspiece D-at points L
and M and attached to revolving bar C. by pins B and F. said bar being fixed to
gunwale H and outrig G by swivel pins J. and N. Sections A and E may be
either straight or elbow shape.
