page_text: I, MAX GEIRE, of Bismarckstrasse, Rath, near Düsseldorf, in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
The usual arrangements for transmitting movement for ordinary purposes by
means of floats swinging under the action of the waves of the sea are such that a
reciprocatory or rotary movement is transmitted on the rise and fall of the floats
or floating bodies, or when a ratchet gearing is employed as transmitting device
a ratchet movement is produced only on the descent, or only on the ascent, of the
floating body.
In the wave motor which forms the object of the present invention the trans-
mission shaft undergoes a rotation in the same direction both during the upward
movement and also the downward movement of a float swinging on a point on a
buoy or float. For this object the connection of two ratchet armis with a float is
established in such a way that on the upward movement and also on the down-
ward movement of the float the two ratchet arms make rotations in opposite
directions one to another, whilst during the ratchet movement of the one pawl the
other pawl returns to the position necessary for its ratchet movement.
The floating bodies pivot or swing on a fixed point by means of levers on a raft
or buoy carrying the ratchet gearing. The ratchet pawls are pressed on the teeth
of the ratchet wheel in the ordinary manner by means of springs, and are operated
by a ratchet arm revoluble on the shaft of said ratchet wheel, which shaft is
provided with a flywheel. In the present example two ratchet wheels are arranged
on the shaft each of which is operated by a float.
The two ratchet arms belonging to one of the ratchet wheels are guided by and
connected with the levers belonging thereto by means of links lying on opposite
sides of the shaft in such a way that both on the rise as well as on the fall of the
respective floats the two ratchet arms make rotations in opposite directions one to
another, whereby, during the forward or ratchet movement of the one pawl, the
other pawl makes the return movement to prepare for a forward or ratchet
movement. On the rise and fall of one of the floats the shaft receives from the
floating body two rotations or impulses in the same direction by means of the
double pawl gear.
The transmission of the up and down movement of the floating body takes place
directly from the lever to one of the two arms through a link, but the other
ratchet arm is operated through a link from an arm on the spindle of the lever
so that here also the two ratchet arms make rotations in opposite directions to
one another.
A float arranged at some distance from the buoy on an arm acts to prevent the
upsetting of the buoy in the one direction by means of its buoyancy and in the
other direction by means of its weight.

In order to increase the stability of the buoy a weight is attached thereto by
means of suspension rods and immersed as deeply as possible, which weight

moored to the bottom of the sea.
The flywheel of the shaft is arranged in a casing which prevents the waves
striking against the flywheel and impeding its travel and producing losses result-
ing by friction in the water, and the rotary movement of the shaft is utilized in
the ordinary manner for generating electricity or for other purposes.
As in the present arrangement it is mainly a question of obtaining as even a
travel as possible, several floats with levers of different lengths may be so arranged
that they do not rise and fall simultaneously but at certain intervals of time.

Improvements in Wave Motors.
I, MAX GEHRE, of Bismarckstrasse, Rath, near Düsseldorf, in the Empire of
Germany, 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:-
The usual arrangements for transmitting movement for ordinary purposes by
means of floats swinging under the action of the waves of the sea are such that a
reciprocatory or rotary movement is transmitted on the rise and fall of the floats
or floating bodies or when a ratchet gearing is employed as transmitting device
a ratchet movement is produced only on the descent, or only on the ascent, of the
floating body.
In the wave motor which forms the object of the present invention, the trans-
mission shaft undergoes a rotation in the same direction both during the upward
movement and also the downward movement of a float swinging on a point on a
buoy or float. For this object the connection of two ratchet arms with a float is
established in such a way that on the upward movement and also on the down-
ward movement of the Hoat the two ratchet arms make rotations in opposite
directions one to another whilst during the ratchet movement of the one pawl the
other pawl returns to the position necessary for its ratchet movement.
In the accompanying drawings, Figure 1 is a side view of such a double ratchet
mechanism;
Figure 2 a front view of same;
Figure 3 a modification.
The floating bodies f pivot or swing on a fixed point by means of levers & on a
raft or buoy carrying the ratchet gearing. The ratchet pawls are pressed
on the teeth of the ratchet wheel a in the ordinary manner by means of springs,
and are operated by a ratchet arm & revoluble on the shaft of said ratchet wheel,
which shaft is provided with a flywheel g. In the example shown two ratchet
wheels are arranged on the shaft e each of which is operated by a float f.
The two ratchet arms & belonging to one of the ratchet wheels are guided by
and connected with the levers b belonging thereto by means of links clying on
opposite sides of the shaft e in such a way that both on the rise as well as on the

page_text: fall of the respective floats of the two ratchet arms make rotations in opposite
directions one to another, whereby during the forward or ratchet movement of the
one pawl, the other pawl e makes the return movement to prepare for a forward
or ratchet movement. On the rise and fall of one of the floats f the shaft e
receives from the floating body two rotations or impulses in the same direction by
means of the double pawl gear.
In Figure 3 the transmission of the up and down movement of the floating
body takes place directly from the lever b to one of the two arms d through a
link, but the other ratchet arm d is operated through a link from an arm on
the spindle of the lever b so that here also the two ratchet arms make rotations in
opposite directions to one another.
A float i arranged at some distance from the buoy & on an arm acts to prevent
the upsetting of the buoy in the one direction by means of its buoyancy and in the
other direction by means of its weight.
In order to direct the buoy and the floats always against the waves, a vane or
blade mis arranged on the float or between the buoy and the float which
gives the buoy the direction of the wind.
In order to increase the stability of the buoy a weight is attached thereto by
means of suspension rods and immersed as deeply as possible, which weight
prevents any tipping up of the buoy. The buoy is anchored or otherwise suitably
moored to the bottom of the sea.
The flywheel g of the shaft e is arranged in a casing which prevents the waves
striking against the fly-wheel and impeding its travel and losses resulting by
friction in the water and the rotary movement of the shaft e is utilized in the
ordinary manner for generating electricity or for other purposes.
As in the present arrangement it is mainly a question of obtaining as even
a travel as possible, several floats f with levers b of different lengths may be so
arranged that they do not rise and fall simultaneously but at certain intervals of
time.
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. A wave motor having ratchet gearing for a float pivotting on a buoy (k)
characterized by several floats (f) with lever arms (6) of different lengths being
so arranged that, whilst conveying a ratchet movement to the transmission shaft (c)
of the motor both in their upward as well as their downward movement by means
of two ratchet arms (c) on each, they almost equal in their total action an uninter-
rupted rotation, by their being raised and lowered not simultaneously but at
different times substantially as hereinbefore described.
2. The general construction and combination of parts taken as a whole forming
the improved wave motor, substantially as described and illustrated.
