We, the undersigned ROBERT STEEL, of 2 Midland Place, Bath Road, Holbeck,
Leeds, Engineer, and GEORGE HODGSON, 21 Neville Street, Leeds, Machine Broker,
do hereby declare the nature of this invention to be as follows:-
11
We provide a Platform, composed for conveniance of travelling, of a suitable
number of sections, which can readily be attached together, and form when complete
an annular Platform.
Each section is carried by a pair of Tram or Road Wheels, which travel in and are
guided by a circular recess or groove formed in a double circular Tramway.
Each section is provided with a stepped or thrust Bearing, firmly attached to its
upper surface, in this Bearing revolves a shaft, actuated by Gearing from the shaft
carrying the Road Wheels. The upper end of the upright shaft is bent to a suitable
angle with the central line of the upright shaft, in such a manner that the top of the
shaft in revolving, will describe a circle around the central axis of the shaft.
A Rod or Staff, one end of which is pivotted to the Floor, whilst the upper end is
rotated in a circle, resembles the movement described by the bent end of the
upright shaft.
A stepped cap Bearing is fitted to, and carried by the upper end of the angular
portion of shaft, and on, and to this Bearing, the Ship or Boat to be operated, is
by Bolts and Tie Rods attached.
The jib boom of the ship is free to rise and fall between a pair of Guides secured
to the Annular Platform.

page_text: The Ship being carried by, and partaking of the motion produced by the angular
shaft, and rising and falling jib boom, will represent the appearance of a Heaving
and Rolling Ship.
Another method of producing a similar result, is to mount the Ship on a Ball
Footstep Bearing fastened to the top of the Platform. The central mast of the ship
is formed by a continuation of the Ball bearing Footstep. A crank or Disc Plate
fixed to one end of a vertical shaft, and carried by a revolving Frame work, will
through the medium of a Ball or other joint, communicate a circular movement, to
the mast of the ship. The jibboom being confined in its movement to a rising and
falling motion, it will be obvious that the combined movement, produced by the
crank and jibboom will result in a heaving and rolling movement.
Circular movement is given to the Platform by a motor conveniantly situated.

Means for Imparting a Heaving and Rolling Motion to Ships or
Boats Used in Roundabouts.
We, ROBERT STEEL, of 2 Midland Place, Bath Road, Holbeck, Leeds, in the
County of York, Engineer, and GEORGE HODGSON, 21 Neville Street, Leeds, in
the said County of York, Machine Broker, 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:-
We provide a Platform, composed for conveniance of travelling of a suitable
number of sections, which can readily be attached together, and form when complete
an annular Platform.
Each section is carried by a pair of Tram or Road wheels, which travel in and
are guided by a circular recess or groove formed in a double circular Tramway.
Each section is provided with a stepped or thrust Bearing firmly attached to its
upper surface, in this Bearing revolves a shaft actuated by Gearing from the shaft
carrying the Road wheels. The upper end of the upright shaft is bent to a suitable
angle with the centre line of the upright Shaft, in such a manner, that the top of the
Shaft in revolving will describe a circle around the central axis of the Shaft. A Rod
or Staff, one end of which is pivotted on the Floor whilst the upper end is rotated in
a circle resembles the movement described by the bent end of the upright shaft.
A stepped cap Bearing is fitted to and carried by the upper end of the angular
shaft, and on and to this Bearing, the Ship or Boat to be operated is by Bolts and
Tie Rods attached.
The jibboom of the Ship is free to rise and fall between a pair of Guides secured
to the Annular Platform. The Ship being carried by and partaking of the motion
produced by the Angular Shaft and rising and falling jibboom will represent the
appearance of a Heaving and Rolling Ship.
Another method of producing a similar result is to mount the Ship on a Ball
Footstep bearing fastened to the top of the Platform, the central mast of the Ship is
formed by a continuation of the Ball bearing Footstep.
A crank or Disc Plate fixed at one end of a vertical Shaft, and carried by a
revolving Frame work will through the medium of a Ball or other joint communicate
a circular movement to the mast of the Ship. The jibboom being confined in its
movement to a rising and falling motion, it will be obvious that the combined move-
ment produced by the Crank and jibboom will result in a Heaving and Rolling
movement.
Circular movement is given to the Platform by a motor conveniantly situated.
In order to enable our Invention to be readily understood, and carried into effect,
we now proceed to describe the same, by reference to drawings, in which similar
Figures are used to represent similar parts.
Fig. 2, is a sectional elevation of one section of the Annular Platform, Driving

page_text: Gear, and Angular shaft. Fig. 1, being an enlarged plan of anti-friction Rollers, and
their Frame. Fig. 3, is an elevation, showing the Ship mounted in position. Fig. 4,
a sectional elevation of the angular shaft. Fig. 5, an elevation showing method of
giving the Heaving and Rolling Motion by means of crank, mast, and equivalent for
jibboom.
Refering to Fig. 2. 1, shows one of the Sleepers of the Annular Roadway. 2, one
of the Road wheels. 3, 4, Spur wheels giving motion to the Bevil Pinion 5, and
wheel 6. 7, is the angular shaft, and 8, an enlarged collar or Bearing rotating with
the Shaft, and furnished with Coned Bearing surfaces, on which the antifriction
Rollers 9, 9, revolve. 10, is a Foundation Plate, forming a Bearing for the Angular
Shaft 7, and Pathway for the Conical Rollers 9, 9. 11, is the top Bearing for the
Angular Shaft, and Pathway for the upper set of Conical Rollers. 12, is a Saddle or
Foundation for the reception and attachment of the Ship. 13, represents Rubber
Buffers, absorbing any shock or jar caused by inequalities in the Roadway or
Gearing. Fig. 1, shows a Plan, of the antifriction Rollers, and their Frame, in which
14, is the Angular Shaft. 15, 16, 17, are Rings secured and held together by Stays,
18, 18. 19, being the Conical Rollers.
Fig. 3, shows the Ship in position on a section of the Annular Platform. 20, is the
Guide between whose sides, the jibboom is free to work in an up and down direction.
21, is a Shield enclosing the Conical Rollers, and Angular Shaft.
Fig. 4, shows the stepped Angular Shaft, with thrust Bearings 22, 23.
Fig. 5, shows the means adopted for imparting a Heaving and rolling motion, by
means of Crank, 24, Mast, 25, Footstep 26, equivalent for jibboom 27, and
Guide 28.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is,
1st. The combination of Angular Shaft and guided jibboom.
2nd. The combination of Crank, or Disc Plate, Mast, Footstep, and guided
jibboom.
3rd. The general arrangement and construction of the various parts, shown in
Figures 1, 2, 3, 4, and 5, for imparting a Heaving and rolling motion to Ships or
Boats, used for purposes of Pleasure.
