PROVISIONAL SPECIFICATION.
Means for Preventing Persons Fraudulently Operating Coin Freed
Apparatus.
We, RICHARD THOMAS GLOVER, and John GEORGE GLOVER, trading as
Thomas Glover and Company, of 214 to 222 St. Jobn's Street, Clerkenwell,
London, Gas Meter Manufacturers, do hereby declare the nature of this invention
to be as follows:---
The object of this invention is to prevent persons fraudulently operating the
mechanism of coin freed apparatus, such as by the insertion of a knife or other
instrument in the coin slot which by manipulation might be made the means of
obtaining a supply of material from the apparatus without the insertion of
a coin.
The invention consists in covering the coin slot with a movable shutter, and so
arranging it in connection with a paul or detent, that upon moving the shutter to
uncover the coin slot, the paul, detent, or other suitable contrivance is caused to
engage with or lock the intercal mechanism, which mechanism can only be
operated or moved by means of an inserted coin and closing the coin slot with the
shutter to release the paul, detent, or other contrivance, and so unlock the mechanism
for operation in the usual manner.
In some cases we may arrange a pin or rocking piece in connection with the
revolving shutter that ordinarily covers the coin slot for said revolving shutter to
automatically cause the pin or rocking piece to engage and lock the mechanism
during the time the coin slot is uncovered for the insertion of a coin, and to release
said mechanism the moment the coin slot is again covered by the shutter, the
object sought to be obtained in all cases being to prevent fraudulent movement of
the mechanism by a foreign instrument by locking said mechanism when the coin
slot is open.

Means for Preventing Persons Fraudulently Operating Coin Freed
Apparatus.
We RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, trading as
Thomas Glover and Company of 214 to 222 St. John Street, Clerkenwell, London,
Gas Meter Manufacturers 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 :-
The object of this invention is to prevent persons fraudulently operating the

page_text: mechanisin of coin freed apparatus such as by the insertion of a foreign instrument
in the coin slot which by manipulation might be made the means of obtaining a
supply of material from the apparatus without the insertion of a coin.
The means adopted and the manner in which the above object is carried out
will be easily understood upon reference to the accompanying sheet of drawings in
which
Figure 1 is a front elevation of a box containing the coin actuated mechanism a
portion being broken away to clearly show the position of the check pawl or detent
when the coin slot is open.
Figure 2 is a similar view showing the position of the check pawl when the
coin slot is closed.
Figure 3 is a plan of the coin mechanism box a portion being broken_away to
show the necessary internal parts which are in the position indicated at Figure 1,
and
Figure 4, is a part sectional elevation on the line 1-1 of Figure 1.
In carrying our invention into practice (for example) as applied to coin
actuated mechanism in which a coin when inserted acts as the block to rotate a
notched wheel when a handle or lever is turned or moved by an intending purchaser
we cover the coin slot A with a shutter B and rivet or otherwise fix said shutter
to a spindle C. that passes through the front plate or cover D of the coin
mechanism box and through a bearing pillar E and is then bent down to enter the
notches F of the wheel G to act as a pawl H to resist the forward movement of
said wheel unless the shutter B be first moved over to close the coin slot as shewn
in Figure 2. or a pawl may be fixed upon the end of the spindle C instead of
bending said spindle to act as a pawl.
The coin slot A must be covered by the shutter B before the pawl H is moved
out of the notches F therefore it follows that the wheel G which is fixed to the
spindle that operates the internal mechanism of a coin freed apparatus (say for
instance a gas meter) cannot by any means or appliance be rotated from outside
the coin slot except by legitimately turning the handle J after the insertion of a
disc (coin) of given size which by resting in the pocket K and in one of the
notches F of the wheel G is the means by which said wheel is turned when the
exterior handle J is rotated.
When the shutter B is moved over to open the coin slot for the insertion of
a fresh coin it automatically locks the wheel G by causing the pawl H to enter one
of the notches F as before described.
A rotating shutter L affixed to the coin pocket closes the coin slot A on the
inside and is provided for the purpose of preventing the insertion of a coin
which can only be done when the handle J is turned to bring the slot of the coin
pocket opposite the slot A. M is a locking bar.
Although the invention is described as applied to a coin actuated mechanism
having a notched wheel it is obvious it may be adapted to check the fraudulent
operation of any kind of coin freed or actuated mechanism whether partaking
of a rotary, or rectilinear character.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. As means for preventing persons fraudulently operating coin freed apparatus,
the use of a shutter for closing the coin slot and, the combination with said shutter
of a pawl for engaging the notches or teeth of coin actuated mechanism to
prevent the movement of said mechanism, while the coin slot is open, arranged in
the manner substantially as described and shown.
2. The means for preventing persons fraudulently operating coin freed
apparatus consisting of a shutter connected to a pawl, and so arranging said
shutter and pawl that the internal coin mechanism is automatically locked or

page_text: unlocked by the movement of the shutter to uncover or close the coin slot as
described and arranged substantially as shown.
Dated this 25th day of April 1896.
