PROVISIONAL SPECIFICATION.
A Mechanical Puzzle.
I CHARLES VICTOR ALBERT ELEY of 441 Southwark Park Road London
S.E. Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
:-
This invention consists in constructing a mechanical puzzle of a novel design,
the various parts of which I desire to manufacture from divers materials.
The principal features introduced are as follows:-
:―
A box having a top of glass or other transparent material; and having a
spherical indentation in the centre of the bottom.
An annular ring to fit in the above box, to act as a stop to a disc, the disc being
free to move in auy direction.
A disc having a spherical indentation upon its upper surface at the centre ;
a cup shaped piece affixed on the under surface also at the centre.
and
A ball to lodge in the spherical indentation in the bottom of the herein before
described box, and to carry the aforementioned disc substantially as described.
Another ball will also be contained in the box, and it will be free to move over
all the surface of the disc, and will fit the indentation in top of disc substantially
as described.
I may also modify certain of the parts, such as by placing a needle point, or
other body under the disc, to obtain the same result as by using a ball.
And again I may stamp small projections from the side of the box to take the
place of the annular ring and its uses as heretofore described.

COMPLETE SPECIFICATION.
A Mechanical Puzzle.
I CHARLES VICTOR ALBERT ELEY 441 Southwark Park Road London S.E.
Mechanical 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 :-
This "mechanical puzzle" is one of novel design requiring for its solution,
steadiness of nerve and patience, and has for its object, the construction of a puzzle
for the instruction and amusement of persons in all stations of life.
With this object in view the invention consists in the various novel details
hereinafter described and especially mentioned in my claims.
Figures 1 and 2. in the accompanying drawings are respectively:-The sectional
elevation and plan of the puzzle by which the working of the same will be clearly
seen as set forth.
A represents the top and sides of a transparently topped box, B represents the
bottom of same and has at its centre a small concavity, or a small receptacle upon
its upper surface to receive a ball C which will support the aftermentioned disc ;
D represents a disc having a cup shaped piece affixed on the under side of it,
and a small concavity, or a small hole at the centre of its upper surface to receive
a ball E or other rolling body which is free to move over all the surface of the
disc.
I may modify the disc by having a number of indentations in its upper surface,
for the employment of one or more rolling bodies.

page_text: F represents an annular ring fitted inside of the box to form a stop to the disc,
thereby governing the angle of the rolling conical surface.
Fig. 3. shews an arrangement for supporting the disc upon a needle point or cone,
instead of a ball or sphere.
Fig. 4. represents a section of a box shewing a modified form in which the
annular is removed, and small projections stamped inwards from the sides of the
box to serve the purpose of the annular ring.
It will be seen from the foregoing that to manipulate the puzzle successfully, it
will require steadiness of nerve and patience on account of the disc constantly
forming a rolling conical surface. To complete it the rolling body must be lodged
in the centre of the disc.
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 -
Claim 1. For the specially constructed box, having indentation or concavity
upon the upper surface of the bottom as hereinbefore described and clearly shewn
in Fig. 1. of the accompanying drawings; and the modification thereof as clearly
shewn in Fig. 3 of the accompanying drawings and for the purpose as set forth.
Claim 2. For the aforementioned annular ring hereinbefore described and
clearly shewn in Fig. 1. of the accompanying drawings and for the purpose as set
forth.
Claim 3.-For the aforementioned disc with small concavity in the upper surface
as hereinbefore described and clearly shewn in Figs. 1. and 2. in the accompanying
drawings and for the purpose as set forth.
Claim 4. For the mechanical puzzle complete as herein before set forth and
clearly shewn in Figs. 1. and 2. of the accompanying drawings.
Claim 5. For the modifications as hereinbefore described and clearly shewn in
Figs. 3. and 4. of the accompanying drawings and for the purpose as set forth.
Claim 6. The combination of the mechanical puzzle herein described to be
constructed of any materials size, or modified shapes for the purpose fully and
substantially as set forth.
Dated this 17th day of April 1893.
