PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Imitating the Motion of Ships or
Boats at Sea, for purposes of Amusement at Fairs and the like.
I WILLIAM PARKER Cart & Waggon Sheet Manufacturer 24 King Street
Bury Lancashire do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to improve & give a rocking & pitching motion in
any direction whatever to the boats or structure employed in imitating the motion
of ships or boats at sea. To effect this I use a centre pivot which work in a
corresponding recess, supported on a vertical stay or pillar with the necessary
stays. The whole of the structure which carries the small boats, is secured to
the above mentioned pivot & represents a large ship with the small boats
hanging in the davitts. The whole of the above mentioned structure hangs below
the pivot, being perfectly balanced. This allows the boats also the structure which
carries them, to revolve, rock & pitch as required, thereby giving the nearest
approach to sea sailing with a perfect steady motion.
The above may be propelled by steam or manual power.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Imitating the Motion of Ships or
Boats at Sea, for purposes of Amusement at Fairs and the like.
I WILLIAM PARKER, Cart & Waggon Sheet Manufacturer, 24 King Street
Bury Lancashire do hereby declare the nature of this invention for IMITATING
THE MOTION OF SHIPS OR BOATS AT SEA, FOR PURPOSES OF AMUSEMENT
AT FAIRS & THE LIKE and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement.:-
The object of my invention, is to improve and give a rocking and pitching
motion in any direction whatever to the boats or structure employed in, imitating
the motion of ships or boats at sea. To effect this I use a centre pivot (or its
equivalent) which works in a corresponding recess, which is supported on a vertical
stay or pillar with the necessary stays. The whole of the structure which carries
the small boats, is secured to the above mentioned pivot (or its equivalent) &
represents a large ship with the small boats hanging in the davitts. The whole of
the above mentioned structure hangs below the pivot (or its equivalent) being
perfectly balanced. This allows the boats also the structure which carries them to
revolve, rock & pitch in any direction whatever as required, thereby giving the
The above may be
nearest approach to sea sailing, with a perfect steady motion.
propelled by steam or manual power.
And in order that my invention may be fully understood & readily carried into
effect I will describe the accompanying sheets of drawings reference being had to
the figures & letters marked thereon.
Similar letters refer to similar parts in each view.
Fig. 1 is a general view or side elevation of the apparatus, when arranged for
working by hand or manual power.
Fig. 2 is an enlarged elevation of a portion of the top part of the apparatus when
designed for working by steam power.
In Fig. 1a is the vertical stay or pillar of iron or wood (as may be required)
227

page_text: with the necessary stays a¹ & base all, upon the end of the vertical pillar a is fixed
the recess b in which the pivot c is allowed to revolve, rock & pitch in any direction
whatever.
Attached to the pivot c by means of the braces or stays d is the main structure e
of circular or any other desired shape having a deck & two rows of seats f
running round its outer edges & represents a large ship the centre of which is open
to allow for the oscillation. The structure e hanging below the pivot c balances
itself & is easy of movement as may be required. 9 are the small boats hanging in
the davitts h.
In working this arrangement by hand or manual power, I attach ropes to the
outer edges of the main structure e which are pulled down & drawn round by men,
thus giving the revolving, rocking & pitching motion in any direction whatever, as
before mentioned.
In Fig. 2-a is the vertical pillar with the stays a', upon the end of which is
fixed the recess in which the pivot c is allowed to revolve, rock & pitch, attached
to the pivot c are the braces or stays d which carry the main structure. Under-
neath the stays d & secured to the pillar a is an horizontal disc i having a cam j
round its circumference so arranged that the riser on one side is opposite to a faller
on the other side. Secured to the braces or stays d are brackets k in which are
fixed bowls which roll on the surface of the cam j, & as the structure is caused to
revolve by means of the bevel wheels m & n through the projecting bars r, one side
is lifted up by a riser & the other side sinks down into the recess of the faller,
motion is given to the bevel wheels m & n by means of the chain wheel o through
the shaft p which passes through the vertical pillar a, thus giving at one & the
same time the revolving, rocking, & pitching motion as before mentioned & as
shown in dotted lines.
Having now particularly described and ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is: --
1033
1-The balancing of the whole of the structure on a centre pivot (or its
equivalent) without any other support whatever & as described.
