the angle of the anvil. The coin is in
serted in the chute; it passes through
fins which exert a slight pressure on
the passing coin; it strikes the anvil.
If it is a good coin, it rebounds into
the proper chute and operates the
mechanism. If it rebounds too far or
not far enough it slides into a side
opening, striking a bell to embarrass
a fraudulent customer on its way out.

COIN DETECTOR
This invention relates to a new type
of coin detector based on a principle
not yet used for this purpose. An im
portant object of the invention is to
use a vertical coin chute in which an
adjustable compact anvil is mounted
so that a predetermined rebound of a
valid coin may be accomplished by
adjusting one angle of the anvil to
cause the coin to rebound into a chute
from which it travels to the operating
mechanism of the vending machine.
The invention provides a mechani
cal means for retarding and reducing
the vibration of the coin as it slides
down a chute, whereby each coin of a
certain kind will have the same trajec
tory after striking the same anvil. It
is well known that the vibration of a
coin from side to side as it slides down
a smooth chute causes variations in
coins in different degrees, for instance,
in a new nickel and an old nickel, the
trajectory from the anvil will vary.
Even the same coin repeatedly in
serted in a smooth chute will vary
somewhat in trajectory after striking
the anvil.
Certain adjustm^its can be made
governing the height of the chute and

in the key 9. A downtumed end 17,
approaches but is spaced from the end
of the key 9. An extension 18, is
formed on the lever 11, and extends to
the coin slot 19, which extends through
the door 5. Any form of coin receiv
ing receptacle maybe employed as for
instance the drawer as shown at 21.
The result of this construction is that
when the coin is placed in the slot 19,
it will fall upon the extension 18, and
will drop a short distance or until the
arm 17, engages the key 9, at which
time the arm 14 is raised out of the
recess 16, and consequently the key.
can be withdrawn. As soon as the end
of the key passes outward from under
the arm 17, the coin upon the exten
sion 18, will drop into the box 21, and
the counter-weight 13, will return the
parts to normal position. *
When the key is reinserted, the lock
can be unlocked for the purpose of en
tering, but the key cannot again be
removed until a coin is placed within
the coin chute. This invention can also
be used with a combination lock.

COIN CONTROL LOCK
This invention is an improvement
in coin controlled lock mechanisms.
The principal object of the invention
is to produce a locking arrangement
which is operated through the medium
of a coin after which the device to
which the lock is attached, may be
actuated.
This device is for use in locked re
ceptacles used in stations or rooms
having coin locks attached to the doors
where it is desirable to obtain a reve
nue from its use.
Sufficient room is provided above
the tumblers to house a pivoted lever
11, which is fulcrumed as at 12, and is
provided with a counter weight 13, to
which a downtumed end 14, is at
tached which enters a recess 16, formed
