2 Claims. (Cl. 185—30)
This invention relates to an improved me
chanical movement, particularly for converting
pendulum-like or swinging motion to rotary mo‘
tion or vice versa, and the present application
5 describes an improvement over my prior Patent
No. 1,694,961 granted on December 11, 1928.
One of the important objects of this invention
is the provision of means for converting pendu
lum-like or swinging motion into rotary motion
10 or conversely, a rotary motion to a swinging
motion, and one of the main objects of this inven
tion is the construction of a device which may be
particularly applicable for utilizing certain types
of reciprocating power as, for example, the motion
15 of waves.
Another important object of the invention is
to provide a special type of control means in con
nection with a swingingly operated source of
power which, in turn, operates to impart motion
20 to a rotary element. This control means acts as
a compensator for otherwise irregular move
ments as will quite often occur in the case of wave
motion or the like.
Other and further important objects of the
25 invention will be apparent from the disclosures
in the accompanying drawing and following
The invention, in a preferred form, is shown in
the drawing and hereinafter more fully described.
In the drawing:
Figure I is a side elevation of the improved
machine of my invention, illustrating one em
bodiment thereof.
Figure II is an end View of the apparatus
shown in Figure I, parts being broken away.
Figure III is a view somewhat similar to Figure
I, showing a modi?ed form‘ of the invention.
Figure IV is an end view of the device illus
trated in Figure III.
Figure V is a View of the bottom of the appa
ratus shown in Figure III, illustrating a further
As shown in the drawing:
The reference numeral I indicates generally
the upright sup-ports or framework of the im
proved machine of this invention, the same being
preferably supported on a base or platform 2
which obviously may be modi?ed to suit require
ments, localities or conditions.
Along the top of the supports or frame ele
ments I, a pendulum-like structure ‘I is supported
which has a vane or the like 8 extending there
from so as to present a fairly broad surface for
wave contact. The pendulum is swung from‘ a
55 pivotal point 60, and a roller ‘la is mounted in a
slot 1b in the pendulum ‘I, the same being mount
ed on the end of an arm or crank II.
The slot
‘lb extends practically‘throughout the length of
the pendulum.
The swinging operation or tension of the pen- 5
dulum can be adjusted by means of springs 6
which are attached to extensions 5b of the frame
I, and it will be noted that the pendulum ‘I has
an upwardly ext-ending projection 9 which has an
opening It therethrough, there being a curved l0
rod 5 ?tted through the opening, the curved rod
5 having its ends adjustably supported in the
frame extensions 5b. Bumper springs 50.‘ are
mounted on the rod 5 so as to also further con
trol the action of the pendulum. A weight I6 is 15
?xed to the lower end of the pendulum to assist
in producing a smoother motion.
The crank I1 is ?xedly mounted on the end
of a shaft I8 ?tted in suitable bearings in the
framework I, and upon this shaft is ?xed a wheel 20
3 having a counterweight 3a ?xed at a desired
point on its periphery.
Obviously, swinging of the pendulum ‘I and
vane 8 through an arc of su?icient length will
impart a rotary motion to: the shaft I8 and the 25
wheel 3, the counterweight 3a and the springs
5a and 6 assisting to compensate for the irregu
larities in both movement and power of thrust.
Conversely, a rotation of the fly wheel 3 will
impart a swinging movement to the pendulum by 30
means of the action of the end of the crank I‘! in
the slot in the pendulum. When the pendulum
is used to impart rotary motion to the ?y wheel,
its swing must be su?icient to allow or produce
a complete revolution of the end ‘Ia of the crank 35
In Figures III and IV is described a modi?ed
form of the invention wherein a base 20 supports
side frame elements 22 in which elements is
mounted a rotary shaft 24 supporting a fly-wheel 40
or the like 26. This fly-wheel is provided with two
counterweights 28.
Another shaft 30 extends across the top- of the
framework and supports a pair of pendulums or
vane structures 32, one at each side of the device. 45
The pendulum structures themselves have slots
34 therein in which rollers 35 operate, the rollers,
in turn, being mounted on extensions ?tted to
the ends of cranks 36 fastened on the shaft 24.
As best shown in Figures III and IV, compensat- 50
ing springs are also provided in this case for any
irregular motions, there being two sets of these
springs, one set comprising a pair as shown at 38,
the upper ends of each of the springs 38 being at
tached to a common fastening point 40 near the 55
upper end of the pendulum and having their
lower ends affixed to pins on the corresponding
ends of a cross-bar or the like 42 fastened to the
frame 22.
In addition, there is another pair of compen
sating springs 44, the ends of which are mounted
fly-wheel mounted in the framework, counter‘
weights on the fly-wheel, a pair of reciprocating
elements swingingly mounted on the framework,
and a crank-shaft connection between said ele
ments and the rotary shaft, said crank-shaft con
nection including a roller mounted in a slot in
on an extension 46 near the top of the frame and
the swingable elements, and vanes on said swing
which converge downwardly toward the pendu
able elements projecting outwardly therefrom,
lum and are a?ixed thereto at opposed brackets
together with means for controlling and com
pensating irregularities in the pendulum-like mo
10 48-thereon.
As best shown in Figure V, another set of
springs 50 may be attached to the lower end of
the pendulum, the outer ends of the springs being
mounted on corresponding adjacent parts of the
15 framework 22.
It will be evident that herein is provided a com
pensated mechanism for converting swinging
movement to rotary motion and. which will auto-
matically take advantage of any irregularities, of
20 power or swing which may occur in the source of
reciprocating motion.
I am aware that many changes may be made
and numerous details of construction varied
throughout a wide range without departing from
25 the principles of this invention, and I, therefore,
do not purpose limiting the patent granted here
on otherwise than as necessitated by the prior art.
I claim as my invention:
1. A'device for converting reciprocating to ro
30 tary motion, comprisinga framework, a shaft and
tion of said swingable elements.
2. A device for converting reciprocating to ro—
tary motion, comprising a framework, a shaft
and ?y-wheel mounted in the framework, coun
terweights on the fly-wheel, a pair’ of reciprocat 15
ing elements swingably mounted on the frame
work, and a crank-shaft connection between said
elements and the rotary shaft, said crank-shaft
connection including a roller mounted in a slot
in the swingable elements, and vanes on said 20
swingable elements projecting outwardly there
from, together with means for controlling and
compensating irregularities in the pendulum-like
motion of said swingable elements, said means
comprising helical springs, one end of each spring
being connected to the pendulum and the other
ends being attached to opposed points on the sup~
porting frame.
