Improvements in Automatically Regulated Apparatus for Utilizing
the Movement of Waves.
A communication to me from FRITZ BENDER, of 60, Kaiserstrasse, Frankfurt
a/Main, in the Empire of Germany, Engineer.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent Agents
and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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 follow-
ing statement, and accompanying drawing, that is to say;-
This invention has for its object improvements in automatically regulated
apparatus for utilizing the movement of waves to obtain power, the apparatus
consisting of a floating body which is acted upon by such wave movement, and
is fixed upon a screwed rod or spindle in such manner that the float during the
slowly varying height of the tide (ebb and flow) can automatically adjust itself
to the varying tide level, whilst, at the same time, by the rapid change in the
water level (caused by the height of the waves) an up and down movement of
the rod is effected by means of the float. The accompanying drawing is in
illustration of the invention.
Figure 1 shows a general side view of the improved apparatus applied to
driving air compressing pumps,
Figure 2 is a plan, and
Figure 3 shows, on a larger scale, the arrangement of the float upon the rod.
Upon the piers P are carried the lattice girders G and G1, and upon the upper
girder G is shown fixed an air receiver K provided with a safety valve V, and

pumps Care arranged. The rod K is coupled to the screwed spindle S which is
provided with stops or buffers P1 and P", which limit the movement of the floats
(of which several are shown), and also lessen any shock against the girders G,
and G¹.
The float B is fitted upon the screwed spindle or rod S, which passes through
corresponding screwed threads in both ends or covers K¹.
The operation of the apparatus described is as follows:-The floats B and
spindles S immersed in the water are caused, by the movement of the waves,
to rise and fall. The friction against the screw threads causes, by this rising
and falling, an up and down movement of the air compressor piston rod K S
(Figure 1). The screw thread upon the spindle S is of such length that at the
lowest level of ebb tide the hollow float B always dips sufficiently into the water,
to ensure the necessary upstroke by means of the waves to do the required work.
In Figure 1, the wave lines W L-F L show the highest position at flood tide,
and the lines W L-E L the lowest position at ebb tide.
The size and proportions of the parts may be varied according to the locality
where they are to be used.

page_text: Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The apparatus for utilizing the movement of waves, in which a float B
acted upon by the rise and fall of the waves is carried upon a rod S having a
screw thread formed upon it, so that the float automatically adjusts itself to the
gradual variation of water level caused by the ebb and flow of the tide, but by
the more sudden change of level caused by the movement of the waves the float
communicates, as it rises and falls, an up and down movement to a rod to which
it is connected, the movements of which rod can be utilized, substantially as
described and illustrated.
