Improvements in Machines for Disclosing Articles in Exchange
for a Coin.
I, PERCIVAL EVERITT, of 47, Cannon Street, in the city of London, and 293
and 295, Broadway, New York, United States of America, 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 machines in which, on a coin or the like being placed in a
suitable receptacle, a shutter or the like suitably arranged moves from in front of an
opening.
By my invention the mechanism of such machines is simplified and the action of
the machine is improved.
In order to carry my invention into effect I mount the shutters on suitable levers,
and as will be seen from the accompanying drawings instead of making the case
square, I propose to make the case curved, with a shutter, so curved, that it will slide
within the case itself thereby saving space.
In the accompanying drawings,
Figure 1 is a front elevation of my improved machine having a shutter which rises
when opened.
Figure 2 is a plan of the same.
Figures 3 and 4 are end views, the end of the case being removed and showing the
parts in different positions.
Figures 5 and 6 are central cross sections showing the shutter in different
positions.
Figures 7 and 8 are similar views to figures 1 and 5 but showing my improved
machine provided with a shutter which falls when opened.
Two levers with the shutter attached are mounted on a spindle which is then
connected to a balance spring (or to a counterweight). This spring has at all times
a tendency to raise the shutter. The spindle is carried through the case and forms a
centre for the levers to work on. The shutter itself is held down by a pivotted
trigger a provided with a small catch c engaging with a pin b in the shutter as
shown in the drawings. Attached to this trigger is a coin bucket d. In its normal
condition the shutter e is held down by the engagement of the trigger a and pin b
as shown in figures 1, 2, 4 and 5, of the drawings, but upon the insertion of a coin,
the shutter e is released and assumes the position shown in figure 6, and by the dotted
lines in figure 3.
Any suitable object of interest can be placed in this case and it may be attached
to the interior so as to prevent its being taken out, or it may be attached, if
necessary, by a chain to the inside of the case, so that articles such as show cups,
etc., can be safely placed therein; or the case may be used for exhibiting and
uncovering, ready for delivery, scientific articles or instruments such as opera glasses,
telescopes, magnifying glasses, microscopes and other articles of the same nature
which require to be removed from their case to be properly used.
To prevent the coin bucket d being operated by a piece of wire or the like, I fix
on the case A of the apparatus a small bracket f having jointed thereto a small

page_text: tipping lever g, provided with a weight to normally keep it in the position shown
in the drawings. This lever has a ledge gl at its top and its lower end o² serves as a
lip to close the exit mouth between it and the bracket. On the insertion of a proper
coin in a slot a¹, the said coin in its descent will separate the bottom g' from the
bracket f, and by this action the top ledge g¹ will be caused to assume the position
shown by the dotted lines in figure 3 so that, should a piece of paper be inserted
in the slot, it will be met by the lower arm 92 of the lever, and the top ledge g¹
of the lever will thereby be swung over towards the bracket f and the substance
will be jammed, thus preventing it putting the machine in operation.
The insertion of a wire, thin rod or other similar device held in the person's hand,
will also as soon as it separates the part g2 from the lower end of the bracket f, close
the ledge gl against such wire or article and clamp it tightly.
It is obvious that I can, if desired, arrange my shutter as illustrated in figures 7
and 8, to fall instead of rise; or may dispense with a spring and leave it free to be
lifted by the hand.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I wish to state that I do
not claim broadly the disclosing of articles for a limited time in return for a coin but
what I do claim is,
1. The self-acting lever-shutter combined with a trigger having a notch engaging
with a pin on the shutter, such trigger being actuated by a coin deposited in the
machine.
"
2. In combination the case having a coin-receiving slot, a fixed bracket f and
the gravitating lever g provided with a ledge g¹ at its top, adapted to grip and detain
between itself and the bracket improper foreign substances inserted, and to prevent,
in such a case, the operation of the disclosing mechanism.
3. The improved case for disclosing articles, as herein before described and shewn in
the accompanying drawings.
Dated the 21st day of August 1889.
