I. EDWARD DE LANOY LITTLE of The Mount, Northallerton, in the County of
York, Schoolmaster, 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 invention relates to an improved puzzle the object of which is to solve
arithmetical and orthographical problems.
The puzzle consists essentially of a suitable board divided by four straight and
three circular lines as shown by Figure 1 of the accompanying drawing and having
spaces or recesses at the points where the straight and curved lines intersect as
shown by Figure 2 of the accompanying drawing. Three of the four straight
lines abc, c d e and ei a form an equilateral triangle and the fourth straight
line a g d, runs between the apex of the triangle and the centre of the base thereof.
The circular lines a bgf, be dy and fed gare of such a diameter and are struck
from centres so that each passes through an angular point of the triangle, and the
middle point of each of the sides containing that angle. At the points where
the straight lines and circles intersect are formed seven spaces or recesses x, x, etc.
With this board are seven discs or their equivalents ✗ inscribed either with
numbers or letters, the said dises or their equivalents being adapted to be placed
on or in the spaces or recesses in solving the problem. As a modification the
board inay be made of slate or slate-porcelain or other suitable material on which
the numerals or letters can be written in the spaces and erased at pleasure, in
which case the discs X may be dispensed with, and similarly one or both faces of
the discs or their equivalents may be made of similar material so that the figures
or letters may be temporarily written upon them.
When used for arithmetical problems the chief puzzle is to place seven numbers
say 1, 2, 3, 4, 5, 6, and 7 in the spaces a in such a manner that each of the seven
sets of numbers four of three numbers each on the straight lines and three of four
each on the circles add up to the same number.
A further arithmetical problem is as follows:-Having selected any one of the
seven numbers say 1, 2, 3, 4, 5, 6 or 7 and placed it in the central space, to place
the other numbers in the other spaces so that each of the three sets of numbers on
circles adds up to the same number, and each of the four sets of numbers on the
straight lines adds up to the same number, which is not necessarily the same as
the other.
By using other numbers an infinite variety of arithmetical problems may be set,
such for instance as the following:-To place seven different numbers in seven
cells arranged in the seven lines (straight and circular) in such a manner that the
numbers on every line add up to the same number, which may be selected at
pleasure.
When used for orthographical problems the chief puzzle is to place seven letters,
either selected beforehand or left to the selection of the operator, in the spaces of
the board, so that each set of letters on the seven lines may form a genuine word.
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 :-
(1.) A puzzle consisting of a board or its equivalent divided by four straight and
three circular lines and having seven spaces or recesses at the points where the

page_text: straight and circular lines intersect, and of seven or more discs or their equivalents
inscribed with numbers or letters, as and for the purpose set forth.
(2.) A puzzle consisting of a board or its equivalent divided by four straight and
three circular lines and having seven spaces or recesses at the points where the
straight and circular lines intersect, the said spaces or recesses being adapted to
receive written numbers or letters which can be easily erased, as and for the
purpose set forth.
(3.) A puzzle consisting of a board or its equivalent divided by four straight and
three circular lines and having seven spaces or recesses at the points where the
straight and circular lines intersect, and of discs adapted to be placed in or on
the said recesses or spaces and having numbers or letters printed on one face, the
other face being adapted to receive written numbers or letters which can readily
be erased, as and for the purpose set forth.
