Return movement of the advance bar is limited by a
leather bumper on the left side of the chute assembly.
The thickness of this bumper can be adjusted by
trimming or shimming until the leading edges of the
advance and holding bar teeth are in vertical alignment
The coin advance bar is moved by the advance bar
lever, whose forked end fits over a roller on the
advance bar. There should be sufficient clearance
between the end of the roller and the inside face of the
fork to allow the advance bar to move in and out
against its springs without fouling the fork With the
mechanism in place, the operating hook should not
engage the advance lever until a coin is played. This
adjustment can be achieved by carefully bending the
tang on the advance lever.
The bar release lever is also controlled by the
operating hook on the mechanism. When the hook
pulls down to advance the escalator, the bar release
lever should hold the advance bar firmly against the
back of the chute assembly, allowing the holding bar to
ratchet When the hook returns to the rest position, the
bar release lever should then move down to hold the
holding bar firmly, thus permitting the advance bar to
ratchet Again, adjustment of this component is achieved
through careful bending, when the application of heat
will prevent fracturing of the part.
Attached to a pivot on the right side of the escalator
is the small, toothed advance bar locking lever. It is the
function of this lever to lock the advance bar in the fully
advanced position until the fourth click of the mech
anism allows the operating hook to jump up and
release the lever and advance bar to the rest position.
Conservative use of the bending method should be
employed as needed to obtain this action.
You will note that all of the levers are operated in one
direction by extension springs In all cases, extreme
spring pressure is unnecessary and springs should be
adjusted to provide brisk but not violent return action.
Final adjustment is that of the coin detector finger,
which should be just short of flush with the rear face of
the coin runway when at rest. When a coin is inserted,
the detector finger should not strike the coin so close
to its edge so as to force it askew, a shallow dog-leg in
the finger allows for simple rotational adjustment
As is customary, lubrication is provided by sparing
application of vaseline on the heavy wearing parts
only, and never in the coin runway itself.
If all is correct, operation will be smooth and positive
on the bench and consistently reliable in the machine.

assorted thicknesses, these inexpensive sheets are
easily cut and trimmed with scissors and placed over
paper award cards to protect them from damage by
player's hands or airborne dust and dirt
The second option is clear contact paper, which can
be had at the housewares department of your favorite
hardware store. Applied over the face of metal award
cards, this covering prevents the scratches so often
caused by coins mishandled by careless playera
Laminating the cards in this fashion also forestalls
deterioration or peeling of the painted surface. On silk-
screened plastic cards, the contact paper can be
affixed to the back side to permanently protect them
from crazing or flaking. This same method can be used
with screened glass panels, but once applied, the
lamination can never be removed, so great care must
be exercised.

Diagnosing a coin problem can be a time consuming
procedure. In many instances, there are multiple prob
lems which interact and which must be solved one by
one. My own test for a coin system is to drop in one
hundred coins, shutting the piano off after each coin.
(Be careful not to overheat the motor doing this) If the
system works without fail, one hundred times in a row,
it will usually work for many thousands of times. If it
fails once within a hundred times, it will not be reliable.
Keep depositing coins until one gets stuck or fails to
turn the machine on; analyze the problem, correct it,
and start over. Ultimately, with a lot of patience and
tinkering, the coin mechanism will be reliable and you
will be able to proudly turn on your music machine for
your visitors by dropping in a coin instead of groping
around on your hands and knees trying to find the trip
lever.
