PROVISIONAL SPECIFICATION
An Improved Method of and Means for Propelling Boats and
Barges.
I CHARLES NORMAN GARNER, of No. 230 York Road King's Cross in the
County of London Manure Manufacturer do hereby declare the nature of this
invention to be as follows:-
By means of a fly wheel which is worked by hand power operating upon cogs
and spindles that are connected at the end of same with a propeller shaft which
said shaft operates upon the ordinary propeller a boat or barge can be thus
navigated without any other motive power.

COMPLETE SPECIFICATION.
An Improved Method of and Means for Propelling Boats and
Barges.
I, CHARLES NORMAN GARNER, of 230 York Road, Kings Cross, in the
County of London, Manure Manufacturer, 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 relates to improvements in mechanism for propelling boats
and barges; and in which mechanism cog-wheels are arranged within a framework
and operated by a winch-handle and fly-wheel to enable a screw-propeller to be
rotated by manual labour.
The object of my said invention is to provide mechanism whereby one man can
propel a boat or barge at an equal, if not at a more rapid rate of speed than would
be possible by more men with the ordinary means at present in use.
I now proceed to describe my said invention, reference being had to the accom-
panying drawings and to the figures and letters of reference marked thereon; like
letters referring to like parts in both of the views.
Fig. 1 is a side view of my improved propelling mechanism, parts thereof being
broken away to illustrate more clearly certain parts of the gearing.
Fig. 2, is a front elevation partly broken away, the view being taken in the
direction of the arrow in Fig. 1.
The framework may be constructed. of wood or metal, but preferably of wood.
The framework comprises a rectangular base A, two opposite side-pieces of which
are extended as shewn at a a to support the struts b. A cross-piece o extends
across the base and supports the combined step-block and thrust-block B. The
base supports four uprights D having eight or less stay-pieces d and a cross-piece e
in which is fitted the bearing E of preferably square section to prevent its turning
in its seat.
A shaft F is mounted in bearing blocks f supported by two of the opposite cross-
stays d.
Said shaft carries a fly-wheel G having a handle g, and a bevel
gear-wheel H. A shaft I is mounted vertically in the bearing E and step-block B
and carries two bevel gear-wheels J, K, the former meshing with the wheel H. A
propeller-shaft L is mounted in a bearing-block and the thrust-block B and
carries a bevel-gear wheel M which meshes with the wheel K.
Although I have shewn gearing which would rotate the propeller-shaft L and
propeller (not shewn) at an increased speed compared with the rotation of the
.
1

page_text: fly-wheel, yet I may-when the boat or barge is of great weight,-employ gearing
which would diminish the speed of rotation of the propeller-shaft and thus increase
the power obtainable.
I wish it to be particularly understood that I do not confine myself to the
identical construction herein described and illustrated in the drawings, inasmuch as
various modifications might be made therein without departing from the nature of
the invention.
The manner in which my said invention is operated is as follows:-The frame-
work is securely built or fixed within a boat or barge so that the propeller-shaft
extends through the stern thereof. When the fly-wheel is rotated the power is
transmitted through the bevel-gear-wheels H, J, K, M, to the propeller-shaft L
and propeller, as will be readily understood.
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 what I
claim is :-
The herein described method and means for propelling boats, barges and the like,
said means consisting of the shafts F, I, and propeller-shaft L, said shafts carrying
a fly-wheel and gear-wheels for transmitting power to a propeller, and a framework
for supporting and containing the mechanism, all substantially as, and for the
purposes herein before set forth and illustrated in the drawings hereunto annexed.
Dated this 14th day of March 1893.
CHARLES NORMAN GARNER.
