I FREDERICK CHARLES LYNDE of 48 King Street Manchester in 'the County of
Lancaster Civil Engineer do hereby declare the nature of this invention to be as
follows:-
:―
This invention relates to that class of weighing machines wherein the weight is
only ascertained or indicated on the pre-payment of the proper coin (say one penny),
and the nature of the invention consists principally in the combination with such
machines of an electric battery or apparatus in such a manner that the introduction
of the proper coin into the apparatus shall by making metallic contact between the
wires of the battery or apparatus cause an electric spark or sparks to be produced so
as to illuminate or indicate the proper numeral upon a graduated dial corresponding
with the weight to be ascertained or indicated.
It will be obvious to any person practically acquainted with electrical apparatus
that a very great many different arrangements may be made for causing the presence
of the proper coin to make the metallic contact necessary for developing the spark,
without departing from the principal novel feature of my invention but for the sake
of illustration I will here describe a simple arrangement which may be applied to an
ordinary weighing machine which works in any ordinary manner and indicates the
weight by means of a finger moving in front of a graduated dial. In front of the
dial I fix an opaque disc or mask which entirely conceals the central part thereof
including the movable finger, and only leaves visible the outer circle upon which the
figures are marked.
If there is a glass in front of the dial this mask may be made by painting on the
back of the glass. The finger of the weighing machine moves behind the mask.so
as to indicate the weight when any person or article is placed on the platform, but it
is not visible unless an electric spark is caused to issue from the point thereof across
the numeral opposite which the finger stops.
For this purpose the axle which turns with the finger is in electric connection with
one of the wires of the battery and a ring of metal provided with pivots opposite to
each numeral is let into the face of the dial and is placed in electric connection with
the other wire, but there is a breech of continuity in the wire leading to or from the
027

page_text: battery so that the electric circuit is not complete, and although the presence of a
weight on the platform of the machine will be indicated by the movement of the
finger such movement will not be visible.
But on the introduction of the proper coin into the machine the coin itself will be
casued to complete the electric circuit and a spark or sparks will be given out from
the finger to the point opposite to the numeral where the finger is at that particular
time, and this electric spark or sparks will thus indicate the weight which has been
ascertained by the mechanical portion of the machine in connection with the finger.
The coin may be caused to complete the circuit by falling onto a balanced lever or
into a receiver or other similar device so that its weight will effect the necessary
contact, or it may be introduced into the apparatus by means of a coin slide in which
it is previously placed, and on the pushing of the slide into the machine the coin
itself will act as a key to make the electric contact and on reaching a certain point
it falls out of the slide into a receptacle at the same time breaking the circuit. Or

improvements in weighing Machines.
1 FREDERICK CHARLES LYNDE of 48 King Street Manchester in the County of
Lancaster Civil Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates principally to that class of weighing machines wherein the
weight is only ascertained or indicated on the prepayment of the proper coin (say
one penny) but the same invention is also equally applicable to other analogous
machines used for ascertaining and indicating static or dynamic force or pressure on
prepayment) wherein the required indication is given by the movement of an index
or finger over the face of a dial, quadrant or graduated scale.

page_text: The invention consists in masking or concealing the index or finger and in com-
bining with such machines an electric battery (or equivalent electric apparatus) in
such a manner that the introduction of the proper coin into the apparatus shall by
making electric contact between the wires of the battery or apparatus cause an electric
spark to be produced so as to illuminate or indicate the position of the said finger or
index with regard to the proper numeral upon the graduated dial, quadrant or scale,
corresponding with the weight, force or pressure to be ascertained or indicated.
It will be obvious to any person practically acquainted with electrical apparatus
that a very great many different arrangements may be made for causing the presence
of the proper coin to make the metallic contact necessary for completing the electric
circuit and thus developing the said spark without departing from the principal novel
feature of my invention, but for the sake of illustration I will bere describe a simple
arrangement which may be applied to an ordinary weighing machine which works in
any known manner and indicates the weight by means of a finger moving in front of
a graduated dial.
In the drawing annexed to this Specification Fig. 1. represents (partly in elevation
and parily in section) an ordinary dial weighing machine with my improvements
shown as applied thereto.
a, a being the platform, b, the pillar and c, c the graduated dial.
In front of this dial I fix an opaque disc or mask d, d which entirely conceals the
central portion thereof including the movable finger e, e and only leaves visible the
outer circle upon which the figures are marked.
If there is a glass in front of the dial c, e this mask may be made by painting on
the back of the glass.
The finger e, e of the weighing machine moves behind this mask so as to indicate
the weight when any article or person is placed on the platform, but it is not visible
until an electric spark is caused to issue from the point thereof across or to the
numeral opposite which the finger stops.
For this purpose the axle which turns with the finger e, e is in electric connection
with one of the wires of the battery by means of a disc g, which revolves in
mercury contained in a metal trough to which the wire is connected.
The dial is provided with a ring of metal h, h (insulated therefrom) with or without
points opposite to each numeral, and this ring is placed in electric connection with
the other wire, but there is a breech of continuity in the wire leading to or from the
battery k, so that the electric circuit is not complete and although the presence of a
weight on the platform of the machine will be indicated by the movement of the
finger in the usual manner yet in consequence of the said finger being behind the
mask such movement will not be visible.
But on the introduction of the proper coin into the apparatus the electric circuit
will be completed, and a spark, or a succession of sparks, will be given out from the
finger to the point opposite the numeral, where the finger or index e, e is at that
particular time, and this electric spark or sparks will thus indicate the weight which
has been ascertained by the mechanical portion of the machine in connection with the
finger.
In the case illustrated the coin is placed through a slit into a shoot 1, and falls into
a small box m, m (shown enlarged in perspective view at Fig. 2).
This box is supported by a cord or wire n, n passing over a pulley o, o and having
a counterbalance weight p, attached to its other end which is sufficiently heavy to
raise the box to the top when empty. When the coin falls into the box it overcomes
the counterbalance weight p, and causes the box to commence descending being guided
by the fixed wires q. q.
At the side of the box m, m there is a small arm r, which supports by means of
knot or button a cord s, s to the lower end of which is attached a forked piece of
metal t, t. As the box descends the arms of this fork descend into mercury contained
in two glass tubes (see enlarged view Fig. 3).
The wires from the battery dip into or are otherwise in connection with the mercury,
and thus the electric circuit is completed and a series of electric sparks is caused to

page_text: pass from the end of the finger or index to the opposite point on the metal ring (or
vice versa) and thus indicate the numeral to which the finger is pointing.
This discharge of electric sparks continues thus rendering the indication visible
until the box arrives at its lowest point when a plunger u, in the bottom of the box
(see Figs. 2 and 4) comes into contact with a fixed part of the apparatus and causes
the coin to be pushed up out of the box, which latter being thus lightened of its
load is then drawn back by the counterbalance weight p into its original position.
As soon as the army, arrives at the knot or button on the cord s, s it causes the
same to lift the fork t, t out of the mercury and thus disconnects the wires and breaks
the current (see Fig. 2 and 3).
This connecting and disconnecting apparatus forms the subject matter of a separate
application for Letters Patent filed by me and dated 3rd day of December 1887.
If preferred the coin itself may be caused to complete the circuit by falling onto a
balanced lever or into a receiver or other similar device so that it will effect the
necessary contact, or it may be introduced into the apparatus by means of a coin
slide in which it is previously placed, and on the pushing of the slide into the machine
the coin itself will act as a key to make the electric contact and on reaching a certain
point it falls out of the slide into a receptacle, at the same time breaking the circuit.
Or instead of a battery a "Voss" or other form of static induction machine may be
employed the cylinder or disc of which is put in motion by the pushing in of the coin
slide with the required coin.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood that
I am aware of Everitt's patent 16433 (1884) and do not claim anything claimed and
described therein and I declare that what I claim is :-
In that class of weighing machine or other analogous machine for ascertaining and
indicating static or dynamic force wherein the indication is given by the movement
of a finger or index over a graduated dial, quadrant, or scale, the combination of a
screen or mask concealing the movement of such finger or index with an electric
apparatus applied to the said finger or index in such a manner that upon the introduc-
tion of the required coin into the apparatus the electric circuit is thereby completed
and an electric spark or sparks, is or are caused to proceed to or from the point of
such finger or index and thus to indicate or point out the particular numeral on the
disc quadrant or scale opposite to which the masked or hidden finger or index has
been moved and which corresponds to the amount of weight or static or dynamic
force to be ascertained.
