KENNETH HUGH BUCHANAN 9, New Broad Street, London, E.C., Civil Engineer
JAMES MELLING Engineer 9 New Broad Street London E.C. do hereby declare, the
nature of this invention to be as follows :—
The object of this invention is to supply a mechanical toy, which will give amuse-
ment as a house game. For the purposes of my invention, I attach to some part of a
circular case, two or more figured discs, fitted with a small ratchet wheel or each and
made so as to revolve on small spindles. I use for the purpose of turning the discs,
a V shaped or angular spring with indented ends, so that when pushed forward by
means of a knob placed outside, attached, through a slot, to center of spring, the
indentations or teeth fit into the small ratchet wheels attached to discs and so contract
the two arms of spring, which on being pulled back or released, caused the discs to
rotate. In the top of circular case have two or more appertures, which, on the
discs being stopped, allow the numbers or figures on the discs to be exposed, but
preventing any interference with the rotary motion of the discs, the spring alone
giving the power & stopping the revolution.

COMPLETE SPECIFICATION.
A New Mechanical Toy.
We, KENNETH HUGH BUCHANAN, and JAMES MELLING, both of 9, New Broad
Street, in the City of London, 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, and accompanying drawing, that is to say :-
Our invention relates to a mechanical toy, having revolving discs carrying numbers,
figures or other devices, upon their upper surfaces, one of which devices upon each
disc can be seen at a time through openings in a fixed plate above, and the discs
being set in revolution and stopped by means of an external knob or handle.
The objects of our invention are first to ensure the stoppage of the revolving dises
in such position that the devices upon them are always exactly under the openings in
the plate above, and secondly, to provide means for easily setting the discs in revolu-
tion and stopping them when required.
The accompanying drawing is in illustration of our invention, in which
Figure 1 is a side view from above of the toy, with the cover removed,
Figure 2 is a transverse section through the centre, and
Figure 3 a transverse section through the openings in the plate above the revolving
discs.
Figure 4 is a view from below of the mechanism by which the discs are made to
revolve and stop; and Figure 5 is a separate view of one of the revolving discs.
Similar letters refer to similar parts throughout the several views.
a is a box or case in which the toy is contained and which is covered by a remove-
able lid. b is an upper plate fitted into the case a, and having openings c, d, through
which the numbers or other marks upon the revolving discs below can be seen.
(In the drawing dots from one to six, similar to those upon ordinary dice, are
shewn).
e and ƒ are the revolving discs the spindles of which turn in bearings in the
plate 6 and in a frame g, and h, i, are small toothed wheels or pinions (having six

page_text: teeth) upon the spindles. k is a bent spring the points of which have teeth or
points l, m, which engage between the teeth of the wheels h, i and n is a sliding bar
to which the spring is fixed, a stud or handle o being also fixed to the bar n and
passing through the slot
in the plate b.
The bar n is guided as shewn at r.
If the stud o be drawn sharply back, so that the spring k is brought into the
position shewn in dotted lines in Figure 4, the toothed wheels hi and the discs e
and are set in rapid revolution and continue moving for a considerable time.
When it is desired to stop them, the stud o is pushed forward into its original
position, the points or teeth l, m, of the spring engaging between the teeth of each
wheel so that the marks or devices upon the discs e and fare stopped exactly
under the openings c d, as shewn in Figure 1. The operation can be repeated
as often as desired, the figures seen through the openings c d constantly varying,
and great amusement being caused by the speculation as to what combination will be
next to appear.
It is evident that instead of two, any other number of revolving discs may be
used the spring k having a corresponding number of arms, and the plate b the same
number of openings.
We do not claim broadly the use of a revolving disc having numbers or other
devices upon its upper surface, but
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
b
The combination of the plate 6 having openings c, d, the revolving discs e, f, and
toothed wheels h, i, with the spring k having pointed arms / m, fixed upon the sliding
and the stud or handle o, all arranged and operating substantially as set forth
bar
n,
and shown.
