ing from the air compartment F', of tank F,
and with the other g', connects a valved pipe
I' opening from the vacuum chamber F.
J J' indicate slide rods, which have cut off
5 valvesjj', arranged to be reciprocated in uni-
son but in reverse directions to alternately
open and close the ports g2 g, and g gl. To
this end the slide rods J J' are connected by
means of link members g' with the opposite
to ends of a centrally pivoted lever arm K, piv-
oted at kon a bar L secured on the cross head
bearing 1i at a point below the crank rod N
to which the cross head O is attached. Near
the outer end of the cross head frame is cen-
j1 trally pivoted a lever P the ends of which are
connected by the pitman rods Q with the le-
ver K which lever as also the lever P has an
upwardly projecting stud ' p' which studs
project up in the path of the reciprocal move-
2o ment of the cross head.
The manner in which my improved appa-
ratus operates is as follows, the buoy being
so arranged as to give the greatest rise and
fall of water caused by the wave, say the
25 buoy contains air down to the trough line of
wave, and the wave equals in perpendicular
height the crest line of wavo. When the wave
strikes the buoy the water rises within it to
the crest line, this forces the air in the buoy
30 through the pipe --E', into air chamber F',
valve pipe II being at this time closed; as
the wave recedes, the check valve e' in pipe
E' will hold the accumulated air in the said
chamber F'. The fall of the water in the
35 buoy (the valve in pipe I being closed) draws
air out of the compartment F2 through pipe
D, and its valves into the interior of the buoy,
and as each succeeding wave rises and falls
the process is repeated until the capacity of
40 the machine is reached or an equilibrium be-
tween the compressed air and weight of wa-
ter is reached, then as each succeeding wave
comes and goes, there will be but a small mar-
gin of reciprocal action between the water
45 and compressed air, but the smaller the air
space in top of buoy is reduced, by the oper-
ation of the wave, the greater will be the com-
pression in tank section F' and the greater
the vacuum in F2. After the required press-
50o ure is stored up, the valves in pipes H II' are
opened, which allows for an application of
the air in the piston X and as the piston is
operated the cut offs over the ports g5 g3 g2
and g4 will be alternately shifted through the
55 cross head engaging with levers L and P to
reverse the piston travel, the air exhaust be-
ing continuously drawn back into the vacuum
chamber F2 and out again into the buoy.
It is manifest that the higher or stronger
6o the wave movement, the greater will be the
air compression, and as the wave lift de-
creases, the air force will also decrease, it be-
ing also obvious that the force may be in-
creased by decreasing the area in the dome
65 or enlargement of the buoy, or increasing thediameter of the piston according to the height
of the wave.
The funnel on top of pipe E is constructed
in length nine times the diameter of the pipe
and the mouth three times the diameter of 70
such pipe E.
At the top of the dome portion a' is ar-
ranged a hollow conicallike chamber in which
is held an electric light the wires of which
pass down through the pipe E, from which at 75
a point on the shore they pass out and con-
nect with the proper electric generating de-
vices, (not shown.)
Having thus described my invention, what
I claim, and desire to secure by Letters Pat- 8o
ent, is-
1. A wave motor mechanism comprising an
air holding tank, an air buoy or chamber,
having an open bottom disposed at a point
below the trough line of the wave, and an up- 85
per portion extended above the crest line,
and a pipe connection extended within the
buoy opening into the upper or extended por-
tion, said pipe communicating with the air
holding tauk and formed with back pressure 9c
valves, all arranged substantially as shown
and for the purposes described.
2. A wave motor comprising an air holding
tank, an air buoy having a dome portion ex-
tended above the crest line of the wave, and 95
an open bottom disposed below the trough
line of the wave, a pipe connection between
such buoy and the air holding tank, having
one end extending up into the dome portion
of the buoy and provided with a back air oo
pressure check valve, all arranged substan-
tially as shown and described.
3. In a wave motor mechanism in combi-
nation, an air buoy having an air chamber
at its upper end, in which air is forced by the 1o5
impact of the wave, an air holding tank hav-
ing a compressed air compartment and a par-
tial vacuum compartment, pipes D and E con-
nected with such compartments and extended
into the air chamber of the buoy, the pipe Iro
D having an automatic valve over the outer
face of its free end, and a back air pressure
valve, the pipe E having a back pressure
valve, all substantially as shown and de-
scribed. 115
4. A wave motor mechanism, comprising a
hollow open bottom buoy fixedly held in the
sea having a compressed air holding portion
at its top, air and vacuum tanks, having
valved pipe connections opening into such 120
air holding portion of the buoy, an air engine
having its inlet and exhaust connected by
valved pipes with such tanks, all arranged
substantially as shown whereby as the com-
pressed air from one tank will serve to oper- 125
ate the engine from one side, the vacuum
will also serve to operate it upon the other,
substantially as specified.
5. In a wave motor the combination of the
air holding tank, the supporting frame dis- 130
