Year: 1897

page_text: Date of Application, 11th Mar., 1897-Accepted, 19th June, 1897
We, GEORGE FRANCIS LA CLOCHE, Rentier, of 21, Beau Rivage, St. Clements,
Jersey, and CHARLES SIDNEY DEANS, Rentier, of Roseden, Longuevillo, Jersey, 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:-
DESCRIPTION OF THE PYRAMID OR FLATTENED CONE (PT. 1).
This part is made of wood or other material & is flat at the top & bottom.
The height of pyramid from the top to the base is about one inch.
The bottom or base is of about 3 inches diameter, & the diameter of the top is
about one inch.
There are three holes made in this top, & each of such a size to suit the balls used,
in this puzzle, such holes being of about one third the depth of the balls used; these
holes are coloured respectively, red, white, & blue, & are dispersed in the shape of a
triangle, of about one half inch sides.
The said pyramid is grooved round its circumference, starting from the base
& gradually rising, & diminishing the size of circle as it goes round the pyramid,
towards the top, in the form of a screw thread, & finishing in the flattened top,
& level with its surface, & close to the centre of any one side of the triangle formed
by the three holes.
This groove is very slightly hollowed in the centre, throughout its whole length
from the bottom to the top of the pyramid, to form a trough for the balls to run in.
This groove makes about three complete turns round the pyramid before reaching
the top, & the rise made by the groove from the base to the top is kept at the same
angle throughout.
DESCRIPTION OF THE THREE Balls (Part 2).
These balls to be perfectly round & are made of metal, or other substance & are of
about three sixteenths of an inch in diameter.
Each ball is of a different colour, to match the holes in the top of the pyramid,
i.e. red, white, & blue.
DESCRIPTION OF THE Box (PART 3).
This box is round, & the bottom & sides are made of cardboard, wood, or other
material, the top being made of glass. The diameter of the top & bottom of this box
is about one half inch larger than the diameter of the bottom of the pyramid, & the
depth inside is about one quarter inch more than the height of the pyramid.
The pyramid (Part 1) is fixed to the centre of the bottom of this box, which box
being larger than the pyramid, gives a play of about one quarter inch all round the
base of the pyramid.

page_text: The object of this puzzle is to get the three coloured balls to travel, in the groove,
round the pyramid, either singly or together, from the base to the summit, & there to
get each ball into the hole which corresponds with its own colour, so that the red ball
will be in the red bole, the white ball in the white hole & the blue ball in the
blue hole.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed, we declare that what we
claim is :
1st. The novelty in that three coloured balls & 3 holes are used in this puzzle.
5
2nd. The hollow groove running round the circumference, up which the balls have 1
to travel.
