Improvements in Oscillatory Gravity Motors.
1, 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 motors, by which the waste
energy resulting from the oscillatory or irregular motion of a vehicle, floating vessel,
a man or animal walking, may be utilised to operate machinery of any kind, or
moving advertisements.
In carrying my invention into effect I arrange a compound ratchet gear upon a
spindle, suitably supported in and by bearings, brackets or the like, upon a base
plate, or within a suitable case, the latter being suspended freely so that the
centre of gravity is practically constant, no matter what may be the degree or
rapidity of oscillation of the vehicle, vessel or other contrivance to which it may be
adapted. Pallets or pawls are arranged to engage with the teeth of the compound
ratchet gear, and these are placed so that a pin or stud fixed to the oscillating
vehicle or the like, may operate said ratchet gear, and produce a continuous rotary
movement in one direction, and the spindle thereof may be coupled directly, or by
the intervention of suitable gearing, to the machinery, or moving advertisement that
is to be driven. In order that a very slight oscillatory motion may produce an
equivalent rotary movement of the spindle aforesaid, I may, instead of toothed
ratchets, employ circular discs, with smooth peripheries, and upon a frame working
freely upon the spindle and operated by the pin or stud before referred to, I pivot
one, two or more semi-circular pawls or cams, so that they freely slip when the motion
of the frame is retrograde, and grip the disc when moved in the opposite direction,
being kept in slight tension thereon by means of counterbalances, springs, loose
chains or equivalent devices for that purpose.

COMPLETE SPECIFICATION.
Improvements in Oscillatory 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 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 motors, by which the waste
energy resulting from the oscillatory or irregular motion of a vehicle, floating vessel,
a man, or animal walking, may be utilised to operate machinery of any kind or
moving advertisements.
In carrying my invention into effect I arrange a compound ratchet gear upon a
spindle, suitably supported in and by bearings brackets or the like upon a base
plate, or within a suitable case, the latter being suspended freely so that the centre of
gravity is practically constant, no matter what may be the degree or rapidity of
oscillation of the vehicle, vessel, or other contrivance to which it may be adapted.
Pallets or pawls are arranged to engage with the teeth of the compound ratchet
gear, and these are placed so that a pin or stud fixed to the oscillating vehicle or
TD 07

page_text: the like, may operate said ratchet gear, and produce a continuous rotary movement
in one direction, and the spindle thereof may be coupled directly or by the inter-
vention of suitable gearing, to the machinery, or moving advertisement that is to be
driven. In order that a very slight oscillatory motion may produce an equivalent
rotary movement of the spindle aforesaid, I may, instead of toothed ratchets employ
circular discs with smooth peripheries and upon a frame working freely upon the
spindle and operated by the pin or stud before referred to, I pivot one, two, or more
semi-circular pawls or cams so that they freely slip where the motion of the frame
is retrograde and grip the disc when moved in the opposite direction, being kept in
slight tension thereon by means of counterbalances, springs, loose chains, or
equivalent devices for that purpose.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in which :-
Fig. 1. represents an elevation of an apparatus constructed according to this
invention.
Fig. 2. is plan view of the same.
The same letters denote the same parts in both figures.
S is a lever pivoted at W to an outer case X. The said lever carries two
rods R R' connected to a lever I oscillating upon a spindle P and carrying semi-
circular pawls 0 0 0 0 engaging with grooved wheels p p attached to a
roller N. The case X is suspended at Z by means of links Y and a pin T on the
lever S passes through a slot U in the case. Said pin T engages with a socket V
attached to the vehicle or the like, the oscillation of which causes the case X to
swing and to operate the mechanism shown in Figure 1. N N are rollers carrying
an endless band Q for advertising, or like purposes. P is the axis of the before
mentioned grooved wheels and is the spindle around which turns the second
roller N.
I wish it to be understood that, in place of the grooved wheels p p¹ and pawls OO¹
OOI may employ ordinary ratchet wheels and pawls.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
I. In oscillatory gravity motors the use of a case containing the mechanism to
be actuated suspended by means of links to a vessel or vehicle, the oscillation of
which vehicle or vessel causes the said case to vibrate and produce continuous rotary
motion of the inclosed mechanism substantially as set forth.
II. In oscillating gravity motors the combination of a grooved wheel caused to
rotate in one direction by means of approximately semi-circular pawls with a
swinging suspended case, and a pivoted lever actuated by a pin attached to a vessel
or vehicle substantially as set forth.
III. In oscillatory gravity motors the use of ratchet or grooved wheels caused to
rotate in one direction by means of pawls attached to a lever contained in a swinging
case and oscillated by means of rods pivoted to a second lever vibrated by means of
a pin attached to a vehicle or. vessel substantially as set forth.
IV. The improvements in oscillatory gravity motors substantially as hereinbefore
described and shewn by the accompanying drawings and operating in the manner
specified.
