PROVISIONAL SPECIFICATION.
Improved Coin Balance and Base Coin Detector.
I, CHARLES LEXI of 377 Strand in the County of London, Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to provide a cheap, efficient and convenient balance
for coins and the like and mainly for the purpose of detecting base coin when
offered to tradesmen or others in shops, restaurants, offices and like places.
In carrying out my invention I take a plate of metal wood or other suitable
material of a convenient size and shape say for instance about six inches square-
and this is arranged to be secured firmly against or to a wall or partition or to the
side of a piece of furniture say a desk or the like.
To the upper left hand corner or other suitable point of this plate I secure a.
metallic or other block or projection square on its upper face and to this upper face
or bedded in the right hand side of the block I fix a strip of thin steel which
projects therefrom parallel with the upper edge of the plate and horizontally or
nearly so.
I turn up the extremity of the steel strip or attach a ledge thereto and against.
this and on the strip the coin to be tested is placed.
I mark on a graduated scale, preferably the arc of a circle described or nearly so
by the end of the steel strip when depressed, the various values of the coins and
the point to which the end of the strip should descend when weighted by any
particular coin, and it will be found that should the coin be base or light the end of
the balancing strip will not descend to the proper point.
It is well known that base coin is usually got up to represent new genuine coin
and differs materially in weight therefrom so that my detecting balance should
prove to be a cheap and ready means of discovering fraud.

CHARLES LENI 377 Strand London 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 :-

metal wood or other suitable material of a convenient size and shape say for instance
about 6 inches square and this is adapted to be secured firmly against or to a wall
or partition or to the side of a piece of furniture such as a desk or the like.
To the upper left hand corner or other suitable point on this plate I secure a

page_text: I mark on the plate B before mentioned or affix thereto a graduated scale prefer-
ably the arc of the circle described by the end of the steel strip when depressed,
the various points to which the end of the strip should descend when weighted by
any particular coin of standard weight and it will be found that should the coin be
base or light the end of the balancing strip will not descend to the proper point.
It is well known that base coin is usually got up to represent new genuine coin
and differs materially in weight therefrom so that my detecting balance should-
prove to be a cheap and ready means of discovering fraud.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which it is to be performed I declare that what I
claim is
The arrangement and construction of apparatus for detecting base coin as
hereinbefore described or any mere equivalent for such arrangement.
Dated this 15th day of February 1893.
CHARLES LENI.
