PROVISIONAL SPECIFICATION.
Improvements in Oscillatory or Gravity Motors.
I, JOHN JOYCE, of 4 Laurence Villas Lower Edmonton, in the County of
Middlesex, Engineer do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to improvements in oscillatory or gravity motors, by means
of which the force developed by the oscillatory or rocking movement of a vehicle,
floating vessel, or moving animal, may be utilised for the purpose of operating
mechanism or apparatus for any desired purpose.
In carrying out my invention I utilise the inertia of any heavy solid or liquid
body, that does not readily move from a position of rest, or quickly change its
position when subjected to a rapid oscillatory or rocking motion. I may use a
plane surface attached to the oscillating or rocking body, such as a vehicle, vessel
or the like, and place upon said surface a ball or cylinder of any heavy material
or. substance. A certain range of motion is provided within two or more tappets
pivotted within a suitable frame, and connected to any gearing capable of
transforming irregular reciprocating motion into a regular rotary motion in one
direction. The oscillatory movement of the plane surface causes the heavy body
to strike the tappets alternately and thus transmit power and motion to the gearing
operated by them, said force being in inverse ratio to the rate of the impulses.
Instead of the foregoing appliance, I may as an alternative employ a tube,
preferably bent at both ends, and containing mercury or other heavy liquid body.
Two pistons are fitted to the tube, one at each end, and are coupled to the
mechanism to be operated directly, or are caused to operate gearing for trans-
forming the irregular reciprocatory into rotary motion. The heavy liquid being
displaced by the oscillatory movement above referred to, impinges upon one
or the other of the pistons, and thus transmits the motion and power as
required.
Or I may enclose the heavy liquid or a spherical solid within a suspended hollow
vessel, and connect it to the gearing for transforming and transmitting the motion,
so that the irregular movement of diplacement may be caused to produce a regular
rotary movement in one direction.

COMPLETE SPECIFICATION.
Improvements in Oscillatory or Gravity Motors.
I, JOHN JOYCE, of Lower Edmonton, in the County of Middlesex, 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 :-
My invention relates to improvements in oscillatory or gravity motors by means
of which the force developed by the oscillatory or rocking movement of a vehicle
floating vessel or moving animal may be utilised for the purpose of operating
mechanism or apparatus for any desired purpose.
In carrying out my invention I utilise the inertia of any heavy solid or liquid
body that does not readily move from a position of rest or quickly change its

page_text: position when subjected to a rapid oscillatory or rocking motion. I may use a
plane surface attached to the oscillating or rocking body such as a vehicle, vessel
or the like and place upon the said surface a ball or cylinder of any heavy material
or substance rolling between two or more tappets and connected to any gearing
capable of transforming irregular reciprocating motion into a regular rotary motion
in one direction or otherwise.
The oscillating movement of the plane surface causes the heavy body to move
the tappets from side to side alternately and thus transmit power and motion to
the gearing operated by them. Instead of the foregoing appliance I may as an
alternative employ a tube preferably bent at both ends containing mercury or
other heavy liquid body. Two pistons or diaphragms are fitted to the tube one
at each end and are coupled to the mechanism to be operated either directly or are
caused to operate gearing for transforming reciprocating into rotary motion. The
heavy liquid being displaced by the oscillatory movement above referred to exerts
pressure upon one or other of the pistons and thus transmits the motion and power
as required, and in order that my invention may be the better understood I will
proceed to explain the same with reference to the accompanying sheet of drawings
in which
Figure 1 represents an apparatus for converting oscillating into reciprocating
motion (adapted to be operated by a ball) constructed according to this
invention.
Figure 2 represents a similar apparatus operated by a column of mercury or
other heavy liquid contained in a bent tube.
The same letters denote the same parts in both figures.
A is a ratchet wheel constructed so as to be capable of rotation in one direction
only by means of the pawls B, B₁ attached to the vibrating lever C, which lever
is driven in the apparatus shewn in Figure 1 by the arm D attached thereto.
The lower end of the arm D is attached to a link E which connects the pendant
levers F F pivoted at H H', G is a heavy ball rolling on a plane surface I
forming part of or attached to the vessel or vehicle whose oscillations it is desired
to utilise. J is the shaft turning in bearings K to which the wheel A is secured
and from which the power is conveyed L L are bearings secured to the frame M
in which the pivots H H are secured.
In some cases the power may be taken from the levers F F by means of the
rods N N shewn in dotted lines if it is desired to drive reciprocating instead of
rotary mechanism direct.
In Figure 2 the lever C is caused to vibrate by means of the pistons 0, 01
connected thereto by the rods P, P¹, these pistons are raised by the movement of
the column Q of mercury or other heavy liquid contained in the bent tube R the
ends of which are bored or otherwise prepared to receive the pistons O, O¹. S. S.
are the cylinder covers.
Instead of the lever C operating the ratchet wheel A it may be connected at each
end to the bell cranks shewn in dotted lines Figure 2 from whence machinery
may be actuated by means of rods connected to the upper ends of the bell
cranks.
It is obvious that by using double acting ratchet gear or "La Gareusse'
levers each stroke of the pistons or movement of the ball may be utilised to
drive the ratchet wheel A the revolution of which would be practically
continuous.
I do not bind myself to the exact details of the apparatus shewn in the drawings
as these merely show two methods of applying my invention to driving mechanism
by means of the oscillation or rolling of vehicles or vessels but,
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 :-
1st. In oscillating or gravity motors the use of a heavy sphere or cylinder the

page_text: movements of which from side to side is caused to produce a continuous rotary
motion in one direction substantially in the manner hereinbefore specified and
shewn at Figure 1 of the accompanying drawing.
2nd. In oscillating or gravity motors the use of a column of mercury or other
heavy liquid contained in a tube, either straight or bent as shewn at Figure 2,
acting on pistons or diaphragms to actuate a vibrating lever and produce continuous
rotary motion in one direction substantially in the manner herein before specified
and shewn at Figure 2 of the accompanying drawing.
3rd. The modification of the apparatus mentioned in Clains 1 and 2 whereby
the motion of a ball or fluid is caused to operate machinery direct substantially
as described and shewn in dotted lines at Figures 1 and 2 of the accompanying
drawings.
