toward the bottom rear of the right side plate. More
commonly, the action is accomplished by means of a
lever which senses a pin mounted in the side of the
takeup spool gear. As the takeup spool turns, the pin
neutral position, so neither the takeup spool nor
rewind disc are engaged. Two: the lock lever for reel

arms cause the reel turning driving disc and sprocket
to be engaged. Four a lever pushes the pump pneu
pushes the lever down. In this style of changer, the
lever unlatches a large wooden valve which falls shut,
closing of a huge leak into the vacuum system and
allowing the instrument to play. The vacuum port, valve
and latching mechanism are mounted on the changer
mounting board to the right of the roll changer.
After the vacuum dumping valve (or action cutoff) is
in the play mode, the piano plays a song. At the end of
the song, hole 1 is perforated in the music roll, operating
the shutoff valve and turning the motor off. The music
roll is now ready to play the next song, but the changer
reel is locked, preventing the selector knob on the
outside of the case from being turned for selection of a
new roll while the old one is still on the tracker bar.
When the next coin is deposited, the motor starts and
the next song plays and shuts off. After the last song on
the roll — there are usually five or six songs per roll —
the rewind hole 75 is punched. A small pneumatic
located at the right end of the roll changer mounting
board (identified as part number W2A294M on the
drawing) pushes the lever, latching the bell crank for
reversing into the rewind position. (Early style changers
have a rotating cam instead of the disc. This cam
pushes another bell crank downward instead of side
ways, but the principle is the same). The roll drive gears
disengage, the rewind disc 61X engages with the
music spool rewinding disc 7X, and the roll begins to
rewind. Simultaneously, the player action is shut off (by
means of the little pallet valve and action cutoff, or by
the vacuum dumping valve). In the style of changer
having a large dumping valve, the valve is held up by a
latch.
When the roll is finished rewinding, the leader wire is
pulled out of the slots in the takeup spool, pulling the
transfer arms up. As soon as the transfer arms begin to
move upward, a linkage (98X) allows a spring to pull the
"takeup spool latch" (99X, not shown) into notch in the
right hand flange, locking the takeup spool with the
leader wire slots facing upward, ready to accept the
next leader wire. As the wire continues to pull the
transfer arms up, four more things happen almost
matic open, pumping air out of the shutoff pneumatic in
the coin switch mechanism. If only one coin was
deposited, the switch in the coin mechanism opens,
shutting off the motor. The piano is now off, ready for
insertion of another coin and a new cycle. Or, if several
coins were deposited, one credit is subtracted from
the accumulator, the reel turning cam turns the reel
1/6 of a turn, and the next roll is threaded onto the
takeup spool.
Several things should be noted about the changer
for complete understanding of its operation. When the
piano is idle, waiting for a coin to be deposited, there
may or may not be a music roll on the tracker bar. If
there is, the remaining songs on that roll must be
played before the machine will rewind automatically,
unlocking the reel for manual selection of the next roll.
Also, it should be noted that, technically speaking, one
cycle of the roll changer begins when the roll goes into
rewind and is not completed until the next roll is pulled
down over the tracker bar ready to start playing song 1.
Thus, the changer turns the machine off in mid-cycle to
allow manual selection of the next roll, and the cycle is
not completed until after the next coin is deposited.
In next month's issue of The Coin Slot part two of this
article will discuss WurliTzer roll changer malfunctions
and their remedies.

PHOENIX—Owners of antique slot machines are safe
from the law as long as they don't use them for
gambling, according to an opinion released today by
state Attorney General Robert Corbin.
Responding to an enforcement query from the De
partment of Public Safety, Corbin said a 1981 law
allowing individual possession of slot machines more
than 25 years old may be meaningless because their
possession never was prohibited.
"It is our opinion that the mere possession of a slot
machine of any age is not unlawful," Corbin wrote.
"Mere possession of slot machines is not illegal, and
any slot machines that are not used for gambling may
not be confiscated."
