New or Improved Motor or Apparatus Operated by the Undulatory
Movement of the Sea.
I, ANDERS FREDERIK WINDEL, Manufacturer, of Aarhus, in the Kingdom of
Denmark, 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 :-
<
My invention has for its object a new or improved motor or apparatus by the aid
of which the undulatory movement of the sea may be utilized.
Such a motor or apparatus is shown in the accompanying drawings, and by the
aid of these I will particularly describe my invention and the manner in which it
may be carried into effect.
In these drawings Fig. 1 is a front sectional elevation; Fig. 2 a plan; Fig. 3 an
end elevation, and Figs. 4 and 5 details of my improved apparatus.
The motor or apparatus is intended to be mounted upon a ship, raft, or other
floating structure, and consists of heavy weight Q provided on each side with
wheels A which run on rails secured by flanges K (Fig. 4) to supports S, S¹,
projecting from a frame T pivoted centrally on the pivot y and supported at each
end by rollers v running on rails.
To the weight is secured a rack C gearing with two gear wheels D, E, loosely
mounted respectively on spindles G, F, journalling in the supports S, S', and geared
together by other gear wheels R, H. These gear wheels D, E, carry spring-
actuated pawls d, e, capable of gearing with ratchet wheels keyed on said spindles.
The ratchet wheels are right and left handed respectively so that whichever way
the rack C is moving, one of the wheels D and E will be connected to its spindle,
whilst the remaining wheel will revolve loosely, consequently whichever way the
rack moves each of the spindles will always revolve in one direction, which will be
opposite to that in which the other revolves.
On the spindle G is keyed a bevel gear wheel K and with this gears a second
bevel gear keyed on a spindle M suitably journalled and carrying on its opposite
end a gear wheel N' capable of being raised by collar N" and lever P', but normally
gearing with a large gear wheel N revolving on the pivot y and having geared with
it a gear wheel P secured on a shaft from which the motion of the apparatus is
transmitted to any suitable point.
The supports S, S', are connected together by cross beams D" which also form
stops for the buffers on the opposite ends of the weight to act upon.
In operation the weight slides backwards and forwards according to the movement
of the vessel or floating structure on which the apparatus is fixed, and its motion is
transmitted, through the medium of the double exchange gearing above described,
to the wheel N₁; from thence, when the latter is lowered, it may be transmitted,
through wheels N and P to any suitable point.
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 :-
(1) A machine for utilizing the undulating motion in the sea, essentially
characterised by a heavy weight running on wheels and rails placed in such a
manner on board a ship or other floating structure that the undulating motion
causes it to move both backwards and forwards.

page_text: (2) In the machine mentioned in Claim 1 the use of a rack in connection with
the weight and a double exchange through the cog-wheels D and E so that the
spindle M is revolved always in the same direction whichever way the weight may
be caused to travel.
(3) Mounting the described machine on a movable under-layer capable of
revolving on a solid centre-pivot and supported at each end by wheels so that
the machine may be placed either lengthwise or athwart-ship according to
circumstances.
