OPERATION
The "Series 50" Accepto rs are designed to require a minimum of maintenance and field
adjus tmen t. Detection and rejecti on of undesired or counterfe it coins are determined by size (both
thickness and diamet er), weight, met allic composition, and bounceab ility.
Transf er cradles are used to test the size of the coin. Unde rsize diameter coins will pass be-
tween the legs of the transfer cradle and will be returned. Oversize diameter coins wil l fail to pass
between the transfer cradle and the wiper and wil l be retur ned by actuat ing the wiper operat ing
leve r. In the case of the quar ter acce ptor, an undersize leve r must first be pivoted to unlock the
trans fer cradle. Unde rsize diameter "quar ters" wi ll fail to unlock the transfe r cradle and will be
returne d by actuating the wiper ope rating lever. Coins that are ove rsize in thickness will fail to
pass between the magne t gate and the main channel and will have to be dislodged and returned by
actuating the wiper oper ating lever.
Transfe r cradle s are also used to test the weight of the coin. Underwe ight coins will fail to
overc ome the transf er cradle counte rweight and wil l be returned by actuating the wiper operati ng
leve r.
A magnet is used to test the metal lic composition of the coin. Highly magnetic coin s, such
as steel or iron, will be retained by the magne t and wil l be returned by actuating the wipe r oper-
ating leve r. Coins having comparativel y high magnetic propertie s, such as copper, will be slowed
down by the magnet and will drop off the end of the rail short of the "accept" entrance and be
returned. Coins hav ing little or no magn etic prope rties. such as brass or zinc. will pass through
the magne tic field so fast that they will "overshoot " the "accept" entrance and be returned .

In the case of the Nick el Acceptor , a bounce tester is used to test the bounceability of the
coin . Due to its magnetic properties, a genu ine nickel passes quickly through the magnetic field
and drops off the end of the rail in an arc that cause s it to hit the boun ce tester which, because
of the coin's elasticity, "bou nces" it into the "accept " entrance . A coun terfe it coin pass ing throug h
the magne tic field at the same speed as a genuine nick el will not have the same elastic ity and so
will not have the same "bounce" as a genu ine nicke l and will miss the "accept" entrance and be
returned .
