PROVISIONAL SPECIFICATION.
Improved Means for Utilising the Oscillatory Movements of Waves,
OP of Vehicles or other Objects, for Actuating Movable
Advertisements or other Devices.
`I, JOHN JOYCE, of Lower Edmonton, in the County of Middlesex, Engineer do
hereby declare the nature of this invention to be as follows
:-
My invention relates to an improved oscillatory motor for actuating moveable
advertisements or other devices, and has for its object the production, of a motor
which is actuated by oscillation of a vehicle, boat,, or by the wayes of the sea,
and adapted to the above mentioned purpose by the intervention of suitable
mechanism.
In carrying my invention into effect I employ a pendulum of suitable length,
and which is terminated by a weight. Said pendulum is placed in such a position
that the ordinary oscillatory movement of the vehicle boat or waves may cause it
to vibrate. Two or more pawls or pallets are connected to it so that a ratchet
wheel, or a series of ratchet wheels may receive a continuous rotary motion from the
impulses of oscillation. In order to obtain approximate continuity of said rotary
motion, I may arrange two or more ratchet wheels upon the same spindle so that a
corresponding number of double pawls may engage therewith, and the alternate
oscillations of the pendulum produce a continuous rotary movement.
I may operate the advertising or other devices directly from the spindle before
mentioned, or I may cause the rotation of said spindle to wind up a spring or
weight, which is automatically released when wound, and thus actuates the desired
mechanism or advertising device:
In applying my invention to wave motion, I substitute a float of suitable area
for the pendulum weight herein before referred to, and instead of employing a
vertical suspension thereof, I may support the beam or lever carrying said flont by
a pivot or other bearing in a horizontal or angular direction, the mechanism for
transmitting the power therefrom being substantially the same as in the previous
examples.

Improved Means for Utilising the Oscillatory Movements of Waves,
or of Vehicles or other Objeots, for Actuating Movable
Advertisements or other Devices.
I, JOHN JOYCE of 4 Lawrence Villas, Milbrook Road, Lower Edmonton, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention
aud in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
+
My invention relates to an improved oscillatory motor for actuating moveable
advertisements or other devices, and has for its object the production of a motor-
which is actuated by the oscillation of a vehicle, boat or by the waves of the
sea, and adapted to the above mentioned purpose by the intervention of suitable
gearing

page_text: In order that my invention may be the better understood I have appended one
accompanying sheet of drawings in which
Figure 1 is a front elevation of one form or type of the device, the case or cover
being removed to shew the various parts in their relative positions, and
Figure 2 is an end elevation of the same.
Figure 3 is a view of part of the mechanism thereof shewn detached.
Figure 4 is a plan view of a modification in which a continuous rotary move-
ment is obtained by an irregular oscillatory movement.
Figure 5 is a sectional elevation of the same and
Figure 6 a general view of certain parts of the mechanism shewn detached.
Figures 7 and 8 shew a single and double acting mechanism respectively.
Similar letters of reference indicate corresponding parts in the several views.
In carrying my invention into effect I arrange three or more rollers of circular
or polygonal cross section, a al al upon suitable spindles in a frame A. At one
end the rollers are geared by means of toothed wheels of equal diameter and
pitch. A pendulum B is suspended at b and communicates its oscillatory
movement to the gearing hereinafter to be described, by means of a rod sa
bell crank and rods dd, with reference to Figures 1, 2, and 3. Two ratchet
wheels, e and e¹ are fixed concentrically upon a spindle or equivalent at ſ, whichi
also carries an arm ¼ abutting against a stop m upon the weight o̟ which is
B118pended at concentrically to and with the axis of the top roller a, but eccen
An extension of
trically relatively to the centre of the ratchet wheels e and e¹.
the arm t carrying the weight g also carries a pawl o which engages with the teeth
of the ratchet wheel p the number of said teeth corresponding to the number of
sides of the polygonal rollers a a a. A bent arm pivotted at and extended
therefrom to is so arranged that the rollers a a¹ are prevented from rotating
except when operated, by the weight pawl o and ratchet pa number of stops i
being placed on the face of the lower roller " for this purpose. The action is as
follows;-
h
The continuous oscillation of the pendulum B, from its point of suspension b, due
to the motion of a vehicle boat or the like, causes the cranks' c c to be moved
alternately, so that the rods.d d', actuating the pawls engaging with the teeth or
cogs of the ratchet wheels e e' may alternately feed and slip with each movement
or oscillation of B. The two wheels e & working upon a centre common to both,
have therefore a continuous rotation in one direction, irrespective of the irregularity
of the movement of B. The arm operated by the wheels ee¹ about the centre f
engages with the stop m upon the weight y and thus raises it, the pawlo slipping
over the teeth of p. The two centres and being placed eccentrically relatively
to each other, causes the stop m on the weight to become free of the end of
the arm h when g is sufficiently raised. Said weight then falls, and the pawl o
acting upon the teeth of p causes the rollers a¹ all a to present another face,
these being coupled by means of the gearing as herein before described.
The weight g is shewn by Figure 3 in the act of becoming disengaged. At the
time the end of t presses against the extension Figure 2, and causes the
stop i to be released from the catch j. I may modify this arrangement by
employing a spring instead of a weight g, and I may also use a single roller à the
advertisements or other designs being printed upon an endless band which may
be lathed or otherwise in order to preserve the continuity and regularity of the
various changes...
same
In order to make the motion continuous as set forth in the first part of this
Specification, I may dispense entirely with the weight or spring and utilise the
direct, impulses of the pendulum, through the intervention of proper gearing for
converting the reciprocatory into rotary movement.
Inorder to utilise the forward and backward oscillations of the vehicle or the
like to which my invention is applied, as well as the side movements, or a compound
of both, I employ a modification shewn by Figures 4 and 5. The pendulum B
is freely swung at C by means of a ball and socket, or by a gimbal joint. Th

upper end of the pendulum rod is squared at' or otherwise shaped to fit freely
within a recess in a cross head H so that any movement of B in any direction
may be communicated thereto: Two cross bars or levers G G fit freely upon

are placed upon the spindle D so as to move freely and independently of each
other, and the cross head H is also arranged to move freely, and is prevented
from turning by the square or polygonal head w. When the pendulum is oscillated
in any direction, said movement is repeated inversely by H, the arms of which
are coupled to the cross bars G G¹ by means of links u uu. Therefore,
independently of the direction of motion of B and H, one of the pawls F F F" Fi
must be feeding the ratchet wheel E while the opposite one is slipping, and the
wheel E moves always in one direction, which rotary movement is transmitted to
the device or contrivance which it is desired to work by the spindle D and the
interposition of any suitable gearing. It is obvious that the movement or oscilla-
tion of B and consequently of H may be compounded of two movements, but in
any case the wheel E is rotated in the same direction. I may in certain cases,
in order to produce an approximately continuous movement of D, employ-more
than one wheel E, and may increase the cross bars or pawls to a corresponding!..
extent. Figure 6 is a general view of two of the pawls For F', joined by a
chain that hangs loosely; and by its weight keeps the pawls in contact with the
teeth of the ratchet wheel.
In Figure 7, a single aoting mechanism is shewn, in which the rod M of the
pendulum B is freely suspended at L, and is attached to a cross bar N at its
upper end, which carries two pawls FF engaging with the ratchet wheel E.
Said pawls may be balanced by means of a weight as at F, or by a spring, as
inay be most expedient. A pawl K is pivotted to the framing A, to prevent a
backward movement of E. The inotion of the wheel E is communicated to
the mechanism that is to be driven by means of the spindle thereof centred at L.
Figure 8 shews a double acting mechanism, in which the pendulum B, suspended
at L carries two pawls F, F, engaging with the ratchet wheel E. The pendulum
may be slotted as shewn by the dotted outline, to allow the spindle of E to pass
through it freely. In this modification, the movement of the pendulum to either
side causes the wheel E to be moved in the same direction of rotation. I may in
this case use more than one wheel in order to obtain an approximately continuous
rotary movement, and in this as well as in the other modifications hereinbefore
described, I may vary the construction and arrangements of the various parts to
suit different cases of adaptation without departing from the essential principles of
niy invention. I may also, instead of using toothed ratchet wheels and ordinary
pawls, employ wheels with plain or ground peripheries, and employ friction pawla
to engage therewith.
It is obvious that 1 may apply each or any of the before mentioned devices to a
moving body, or men- with sandwich boards, or structures carried by men for
advertising purposes, the oscillatory movement of walking producing the required
motion and power.
In applying my invention to wave motion alone, I substituto a float of suitable
area for the pendulum B hereinbefore referred to, and instead of employing &
vertical suspension thereof, I may support the beam or lever carrying said float by
a pivot or other bearing in a horizontal or angular direction, the mechanism for
transmitting the power therefrom being substantially the same as in the previously
described examples.
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 :-
First. The method of and meaus for producing an approximately continuous and
regular rotary movement by utilising the irregular vibratory or oscillatory move-
