PROVISIONAL SPECIFICATION.
Improvements in Automatic or Coin-freed Weighing Machines.
I, PERCIVAL EVERITT, of 47, Cannon Street, in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of automatic or coin-
freed weighing machines, the improvements having for object to provide a weighing
machine which shall have a transparent dial arranged in such a manner that none
of the working parts of the machine will be apparent.
For this purpose I employ weighing mechanism constructed in accordance with
the invention forming the subject of my former Application No. 132608, that is to
say, with the working parts arranged below the dial and having a stop on the
vertical rod thereof.
Instead of the coin-bucket being arranged as heretofore, I attach it to the
periphery of a glass disc, which has a hand or pointer painted up or attached to it.
This disc moves on a centre between two other glass plates, the front one forming
the dial of the machine, and the other the back of the case of the machine. Instead
of the front plate forming the dial the rotating disc or plate may be graduated, in
which case the hand or pointer would be stationary on the front plate.
By this arrangement it will be obvious that on a person stepping on the platform
the weighing operation will be performed and the stop lowered in accordance with
the weight of the person or body on the platform. No indication, however, of the
weighing will be given until the required coin be placed in the machine, and which
passing into the coin-bucket will rotate the middle disc until either the bucket or a
suitable stop comes against the stop of the machine, and the weight will be thus
indicated on the dial. On the weight being removed from the platform the bucket
will discharge its contents and the movable disc will be returned to its normal
position by a suitable counterweight or its equivalent.
Dated the 27th day of June 1890.

COMPLETE SPECIFICATION.
Improvements in Automatic or Coin-freed Weighing Machines.
I, PERCIVAL EVERITT, of 47, Cannon Street, in the City of 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-
This invention relates to improvements in the construction of automatic or coin-
freed weighing machines, the said improvements having for object to provide a
weighing machine which shall have a transparent dial arranged in such a manner
that none of the working parts of the machine will be apparent.
For this purpose I employ weighing mechanism constructed in accordance with
the invention forming the subject of my tormer Application No. 13260 of 1889, that
is to say, with the working mechanism arranged below the dial and having a stop
on the vertical rod of such mechanism.
Instead of the coin-bucket being arranged as heretofore, I attach it to the
periphery of a glass disc, which has a hand or pointer painted upon or attached

page_text: to it. This disc moves on a centre between two other glass plates, the front
one forming the dial of the machine, and the other the back of the case of the
machine.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which :-
Figure 1 is a sectional side elevation of a weighing machine provided with my
improvements; and,
Figure 2 is a sectional front elevation:
Figure 3 is an elevation of the upper part of the machine; and,
Figure 4 is a sectional plan of the same.
a indicates the frame of the machine, the weighing platform, and c the vertical
rod, which, as shewn, is operated from the weighing platform through the medium
of the levers d, e, the rod f and the lever g; this rod c moves in vertical guides h, h
and its upper end forms the stop.
i is the glass disc which is carried by a spindle j supported in anti-friction roller
bearings k, k secured to the glass plates l, m, the former of which forms the dial
whilst the latter forms the back of the case behind the disc i. n is the hand or
pointer secured to the disc i and moving over the graduations on the dial l, as shewn
most clearly in Figure 3.
o is the money-bucket which is secured to the periphery of the disc i, and p is the
shoot by which the coins introduced into the slot q are directed into the said money-
bucket. This money-bucket may be of any suitable construction but the bucket
shewn in the drawing is constructed in the manner described in the Specification of
former Letters Patent granted to me No. 10231 of 1887.
r is a stop or tappet also secured to the periphery of the disc and so arranged as
to strike the stop of the vertical rod c.
The operation of the apparatus hereinbefore described is as follows, that is to say,
when a person steps onto, or a weight is placed upon the platform b, the weighing
operation will be performed and the vertical rod c will be more or less lowered.
No indication, however, of the weighing will be given until the required coin is
placed in the machine and falls into the bucket o, thereby causing the rotation of
the said disc i and also the movement of the hand over the graduations of the dial
until the tappet r comes into contact with the stop, that is, the upper end of the
rod c.
s, s indicate pins which are so arranged in conjunction with the bucket o, that
when, as the weight is removed from the platform, the bucket commences to move
upwards, a part thereof will impinge against one of the said pins and discharge the
coin in the manner described in the said Specification No. 10231 of 1887. It is to
be understood that the disc i is so balanced that it can readily operate under the
weight of a coin and return to its normal position when the coin is discharged.
t is the hopper into which the coins discharged from the bucket drop, and by
which they are directed into a bag u or other receptacle. v, v are screens extending
between the glass plates i, m and the disc i for preventing any of the internal parts
of the machine from being seen.
Instead of arranging a hand or pointer in conjunction with the rotating
disc, the said disc may be graduated and work in connection with a fixed hand or
pointer.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. An automatic or coin-freed weighing machine having a transparent dial
arranged to be operated by the weight of a coin and so constructed that none of
the internal mechanism is visible, substantially as described.
2. In an automatic or coin-freed weighing machine, a disc adapted to be rotated
by the weight of a coin introduced into a money-bucket secured to its periphery,
substantially as described.

page_text: 3. The manufacture and use of the improved automatic or coin-freed weighing
machine having a transparent dial substantially as hereinbefore described and
illustrated in the accompanying drawing.
