We THOMAS JOSEPH WALSH Traveller, and LEWIS WILD; Merchant, both of
13 Edmund Place, Jewin Street, in the City of London, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to an instrument for use in testing the goodness of coins by
their resistance to bending and has for its object to provide an instrument whereby
greater power of bending the coin is obtained so that the test may be more easily
applied even by a weak person and without hurting the fingers.
Our improved instrument which may be fixed to the counter or carried in the
pocket consists of a pressure lever jointed to another lever or to a base plate having
one or more notches so inclined that a coin placed therein will be presented somewhat
flatwise to the pressure lever in order that a bending strain may be thereby applied to
the coin.

page_text: We THOMAS JOSEPH WALSH, Traveller, and LEWIS WILD, Merchant, both of
13 Edmund Place Jewin 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 :-
Our Invention relates to an instrument for use in testing the goodness of coins by
their resistance to bending; and has for its object to provide an instrument whereby
greater leverage and consequently greater power of bending the coin is obtained than
with the ordinary coin testers in use, so that the test may be more easily applied even
by a weak person and without liability to hurt the fingers as sometimes happens
when the bending pressure is applied directly to the coin itself.
Our improved instrument which somewhat resembles a pair of nut-crackers may
be held in the hand, or be fixed to the counter; and it consists in the combination
of a pressure lever with a notched lever or base piate having one or more transverse
notches to receive the edge of the coin, the notched lever or base plate somewhat
resembling the ordinary coin tester now in use. The two levers are jointed together
at one end, and the notches are not at right angles to the face of the lower jaw or
base plate but are so inclined that a coin placed therein will be presented to the
pressure lever at such an angle that a bending strain may be easily applied to the coin
by pressing on the said lever.
Reference is to be had to the accompanying drawings forming part of this
specification, wherein figure 1 is a side elevation, and figure 2 a plan, of the instrument
as in use for the purpose of testing a coin. Figure 3 shews a plan view of the lower or
notched lever or base plate, and figure 4 a cross-section on line 1-1 figure 1, of the
upper or pressure lever. The same letters of reference indicate the same parts in all
the figures.
A is the notched lever or base plate and B the pressure lever, the two being jointed
together at one end as at C, so that when separated, they will make an acute angle
with each other. The two levers may be made of cast iron and the upper face of A has
a series of cross notches a a¹ a² in it, of different widths and at different distances from
the joint C. These notches are adapted to receive and hold coins of different thick-
nesses and diameters, and are inclined either towards or away from the joint C so
that a coin inserted therein will be presented at an acute angle to the under face of the
lever B, as shewn in figures 1 and 2, in order that pressure applied thereto may exert
a bending strain on the coin held in the appropriate notch.
In order to prevent the coin slipping out of the notch whilst being tested, the under
face of the lever B is made concave, as shewn in figure 4. The free ends of the
levers terminate in handles and the lever A has holes in it to receive screws for
fastening it down upon a counter or table.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what we
claim is ;-
1. A coin-tester, consisting in the combination of a pressure lever with a notched
lever or base plate adapted to hold a coin edgewise and present it to the pressure lever
in such manner that a bending strain may be thereby applied to the coin, substantially
as specified.
2. The herein described coin-tester, consisting of two levers jointed together at one
end, the one having a concave face and the other having a series of transverse notches
of such widths and at such distances from the joint, as to be adapted to hold coins of
different sizes, and so inclined as to present the coin at an acute angle to the first lever,
as and for the purpose specified.
