I JABEZ WEDDERBURN of 130 Hill Street Peckham, London S.E. Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved letter-scales and coin-tester or
weight-and-size-of-coins-gauge.
The letter scale and weight-tester are both mounted on the same block or bed-
plate which may be portable or fixed when in use.
In carrying the invention into practice I employ a pivoted lever-arm one extremity
carrying weighting means, and the other extremity or arm, divisions and guards
dividing the said arm into spaces so that the weight of the letter or coin, at the
precise position upon the arm where the guards or holding divisions are provided,
will, by balance, exactly represent and indicate whether the letter or coin exceeds,
balances, or falls-short-of the proper weight and in case of the coins the proper
measurement across, or gauge thereof.
According to one construction the weighting-lever and its supporting centre or
axis and brackets are mounted upon a bed-plate or block. The said lever is cast,
of malleable iron it may be, or be stamped up or formed out of plate, with divisions
consisting of deep cross grooves or channels in which the edge of the letter to be
weighed will be received and held whilst the weighing is being effected. The
other arm is weighted permanently so that the divisions will correspond to the half-
ounce, one ounce, two ounces and so forth. For the quarter-ounce or one third
ounce, as the case may be, there is a hinged piece at the end of the weighing-arm
which can be turned outwards to lengthen the arm and add sensitiveness to the
weighing capacity or counterpoise of the last division of the weighing arm;
spring-clip may be put on to the end of the arm to add weight and expedite the
counterpoise. Cross guards on the arm will admit of the heavier coins being placed
on the letter weighing-arm.

With this construction there is mounted a coin-guage-balance fastened to the
bed-plate or block of the letter-scales, for weighing the lighter coins, the lever arm
whereof is weighted to one side of the axis thereof and the weighting and guage
arm thereof is counterpoised and furnished with cross-guards spaced apart
correspondingly to the diameters of the various coins.
Together with the first herein described letter-scales-device or such like means
I combine according to a modification of this invention, the coins-weight-and-size-
guage such as last described upon the weight-arm of letter scales lever-balance-
upon upstanding ears thereupon the lever-balance arm spaced and counterpoised
for weighting the lighter coins of currency as required or necessity may demand.
A set of "money-triers" may be made on the bed-plate, that is dentils with
different spaces between, for testing silver coins.

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 a new or improved letter scales and coin-tester or
weight-and-size-of-coins-gauge.
The letter scales or balance and weight-tester are both mounted on the same
block or bed-plate which may be portable or may be fixed when in use, or in position
for using.
In carrying the invention into practice I employ a pivoted lever arni or balance-
beam one extremity carrying weighting means and the other extremity or arm is
furnished with divisions and guards dividing the said arm into spaces so that the
weight of the letter or coin at the precise position upon the arm of the balance
beam (where the guards or holding divisions are provided) will, by counterpoise or
balance, exactly represent and indicate whether the letter or coin exceeds, balances
or falls short of the proper weight; and, in case of the coins, the proper
measurement across or gauge thereof will be tested.
According to one construction the weighting lever and its supporting centres or
axis and brackets are mounted upon a bed plate or block. The said lever-arm is
cast of malleable iron, it may be, or be stamped up out of plate with divisions
consisting of deep crosswise grooves or channels in which the edge of the letter to
be weighed will be received and held whilst the weighing is being effected. The
other arm of the beam is weighted permanently so that the divisions will correspond
to the half ounce, one ounce, two ounces and so forth. For the quarter ounce or
one-third ounce there may be a hinged piece at the end of the weighing arm which
can be turned outwards to lengthen the arm or a spring clip may be put on to the
end of the balance arm for the same purpose.
Cross guards on the arm will admit of the heavier coins being placed on the
letter weighing arm.
With this construction there is mounted a coin-gauge-balance fastened to the
bed-plate or block of the letter-scales for weighing the lighter coins, the lever ariın
of which coin-guage-balance being weighted to one side of the axis thereof and
the weighing and gauge arm thereof is counterpoised and furnished with cross.
guards spaced apart corresponding to the diameters of the various coins.
Together with the first herein described letter scales device or such like means
I combine, according to a modification of this invention, the coins-weight-and-
size-guage such as last described upon the weighted end of the letter-balance
(ie. the weight-arm thereof). Upstanding ears or supporting brackets are set up
on the said weighted end of the letter balance and on these supports will be placed
the balance centres of the coin-gauge-balance spaced and counterpoised for
weighing and guaging the coins of gold currency or the like as required or necessity
may demand.
A set of "money triers " may be made or secured upon the bed plate of the
combined device.
In the drawings annexed hereto there is shown a construction of letter balance
and cointester made according to this invention.
Fig. 1 is an isometric general view of the combined device.
Fig. 2 is a side view and plan of the letter or main balance arm.
Fig. 3, is a side view and plan of the subsiduary cointester balance and guage.
Figs. 4, and 44, are side and edge views respectively of brackets or standards
for supporting the letter balance arm or beam, on enlarged scale.

position lugs, cast on, of a piece with the bed plate may be provided with holes
for screws, as will be well understood but same are not shown in the drawings.
The main beam B B is centered at b, in open slots of the brackets or supports a..
The upright a of the bracket a is positioned under the weighted end B₁ of the
beam so that said beam will not fall below the horizontal on that side. The side
uprights a of the bracket a is arched over by a loop a, for purpose of facilitating
portability but the open slots of the beam centres will allow of the beam B B' being
readily placed in its centres in said open slots.
Figs. 4 and 44 show a slight variation of this construction wherein instead of
the loop a² the brackets are connected by a rivetted cross bar a. The bottom.

By this device provision is made for a combination of useful articles which have
hitherto been sold as separate articles and further there are no sliding or loose-
weights either to be adjusted or applied; the whole efficacy of the balances.
depending solely for accuracy upon the main beam centres without complication
either of parts or manipulation. It is sensitive in action and withal strong and not.
liable to get out of order.
The bed plate below the bracket a may be varied and the silver coin tester D,.
may be dispensed with without departing from this invention.
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. The new or improved letter scales or balance and cointester gauge.
constructed combined and operating as and for the purpose herein set forth and
shown by the drawings.
Secondly. The combination with a bracket such as a and upright such as a¹, of
the main beam B, B¹, b, carrying as partial weighting means to the weighted
end B' of said beam the supporting bracket 65, and supplementary coin balance.
and gauge C, C, C³, d, e, as herein described.
