Complete Specification Left, 12th Nov., 1894-Accepted, 26th Jan., 1895
An Improved Indicating Apparatus or Telegraph for Use in
Signalling or Exhibiting Scores at Cricket, Billiards, or
other Games, or for other purposes.
I, Major LATHAM CHARLES MILLER BLACKER, Royal Artillery 97 Shooter's
Hill Road Blackheath S.E. do hereby declare the nature of this invention to be as
follows:-
This invention relates to an indicating apparatus chiefly designed to be used for
exhibiting or signalling information such as scores or numbers at games such as
cricket billiards etc. or transmitting any instructions consisting of a combination of
letters words or other symbols.
The main feature of the invention consists in the employment of an apparatus
wherein discs or dials are arranged tangentially contiguous to one another or
superimposed one on the other either concentrically or overlapping in such a
mauner that by rotating the said discs or dials certain indications can be exhibited
as follows, through certain apertures.
The discs or dials are enclosed in a flat case or box and are arranged some
singly, others concentrically others tangentially to each other; others overlapping
one another and pivotting either on the front or rear of the box or on stays down
the centre.
Each disc carries numbers from 0 to 9 inscribed round the edge of its flat surface
and the front of the case has apertures so arranged that only one figure on each disc
can appear at a time.
The scores are thus formed and exhibited by combinations of the figures showing
at any one time, and by increasing the number of the discs arranged overlapping
each other any number up to 5 or 6 figures can be formed.
What is particularly desired to protect by this Specification is the principle of
the overlapping flat discs, each overlapping the next by the width of a figure; an
aperture being cut towards one side of the case, so that any number formed of a
figure from each disc can appear through it.
This apparatus can be used for any purpose where a combination of letters, words,
figures or other symbols is desired to be exhibited.

I, LATHAM CHARLES MILLER BLACKER, Major Royal Artillery of Cardigan
House, 97 Shooter's Hill Road, Blackheath S.E. 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 indicating apparatus chiefly designed to be used for
exhibiting or signalling information such as scores or numbers at games, such as
cricket, billiards, and the like, or transmitting instructions consisting of a combi-
nation of letters words or other symbols.
The main feature of the invention consists in the employment of an apparatus
wherein discs or dials are arranged tangentially contiguous to one another or
superimposed one on the other either concentrically or overlapping in such a
manner that by rotating the said discs or dials certain indications can be exhibited
through certain apertures; as follows:-
The discs or dials are enclosed in a flat case or box and are arranged, some
singly, others concentrically, others tangentially to each other, others overlapping
one another, and pivotting either on the front or rear of the box or on stays fixed
across the centre (inside).
Each disc carries numbers from 0 to 9 inscribed round the edge of its flat surface
and the front of the case has apertures so arranged that only one figure on each disc
can appear at a time.
The scores are thus exhibited by combinations of the figures showing at any one
time through the apertures, and by increasing the number of the discs arranged
overlapping each other, any number up to even 999999 or over could be
formed.
What is especially desired to protect by this Specification is this principle of
overlapping flat discs, each overlapping the next by the width of a figure; an
aperture being cut towards one side of the case so that any number formed by a
figure from each disc can appear through it. This arrangement is used in combi-
nation with other discs or dials placed concentrically one to another or tangentially,
figures from each disc showing one at a time through apertures, and thus composing
numbers.

In the accompanying drawing I have shown how the said invention can be
conveniently carried into practice.
Fig. 1. is a plan in elevation of the proposed telegraph.
B, C, D, are three discs arranged within the case, the two upper ones
overlapping the lower one and carrying numbers from 0 to 9 inscribed round
their edges.
A is an aperture to one side of the front of the case through which one number
at a time from each disc can show.
By turning the discs it is evident that the number 230 can be altered to any
combination forming a number from 1 to 999, a blank space being left on the
lower disc B in place of a zero.
In addition to above discs there are arranged within the case discs E, F, G,
placed E & F concentrically and F & G tangentially one to another and also
bearing numbers inscribed on their edges whereby combinations of figures can be
shown as desired through a frontal aperture A'. A single disc at H. Blank spaces
and a covering patch J. are left where required.

page_text: By using letters instead of figures it is plain that words can be signalled if
necessary in any games.
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 :-
:-
First. An apparatus wherein discs or dials are so arranged overlapping each
other or placed concentrically one on another or tangentially contiguous one to
another in such a manner that by rotating the said discs or dials certain indications
or scores formed by combinations of figures, words, letters, or other symbols+
inscribed in or on the said discs or dials can be exhibited or shown through certain
apertures.
