A New or Improved Apparatus for the Utilization of the Motion of
Water Waves as a Motive Power.
I AUGUSTE BOUDEVILLE of 10 Rue Herbière, Rouen in the Republic of
France Engineer do hereby declare the nature of this invention to be as
follows:-
This invention consists of a raft or float which is placed in the sea (at low water)
at a distance of 50 to 60 yards from the shore according to the locality. Upon
this raft or float, which is made convex in its middle portion where cross rollers
are arranged at distances apart, an iron shaft or arbor is provided so as to rest
between the said rollers.
A vertical cross plate provided at the end of this shaft or arbor is immersed in
the sea to a depth of about 3 yards and at a distance from the end of the raft of
about two feet. This plate is naturally pushed back and forth by the motion of
the waves and gives a corresponding movement to the shaft which is connected by
a pitman to a crank shaft, thus revolving the latter. The raft or float is made
convex in its middle and the rollers are arranged about 18 inches above the middle
in order that they be not submerged in the water. This raft or float is roofed
over with sheet iron and at certain distances apart orifices are arranged for the
purpose of letting through the water so that the rollers are always kept free from
water. At each side of the raft or float a walling is built and along the wall posts
of hollow iron are placed at desired distances apart. Bolts are fastened on the
float to fit in the said iron posts to be guided up and down with the rise and fall of
the tide.

A New or Improved Apparatus for the Utilization of the Motion of
Water Waves as a Motive Power.
I AUGUSTE BOUDEVILLE, of 10 Rue Herbière, Rouen in the Republic of
France, 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 invention consists of a raft or float which is placed in the sea (at low water)
at a distance of 50 to 60 yards from the shore, according to the locality. Upon
this raft or float, which is made convex in its middle portion where cross rollers are
arranged at distances apart, an iron shaft or arbor is provided so as to rest between
the said rollers.
A vertical cross-plate, provided at the end of this shaft or arbor, is immersed in
the sea to a depth of about 3 yards and at a distance from the end of the raft of
about two feet. This plate is naturally pushed back and forth by the motion of
the waves and gives a corresponding movement to the shaft which is connected by
a pitman to a crank shaft, thus revolving the latter.
The raft or float is made convex in its middle and the rollers are arranged about
18 inches above the middle in order that they be not submerged in the water.

page_text: This raft or float is roofed over with sheet iron, and at certain distances apart
orifices are arranged for the purpose of letting through the water, so that the
rollers are always kept free from water. At each side of the raft or float a wall is
built, and along the wall posts of hollow iron are placed at desired distances apart,
bolts are fastened on the float to fit in the said iron posts to be guided up and down
with the rise and fall of the tide.
The device is diagrammatically shown in the annexed drawings in which Fig. 1
is a sectional side elevation and Fig. 2 an end elevation thereof.
A is the float, B the cross rollers, C the longitudinal shaft and I the shaft
revolved thereby. D is the plate at the end of the shaft C and H are the guide
posts supported by the walls F and G.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The device for utilizing the motion of water waves comprising a longitudinally
reciprocatory shaft C, with plate D at the end thereof adapted to give rotary
motion to the shaft 1.
2. The combination with said devices of the float A guided to rise and fall with
the rise and fall of the water level and carrying said devices for the purpose set
forth.
