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.

measured 63 inches high, 19 inches wide and 18
inches deep. This model also had a spacious merchan
dise cabinet with mirror, but had a roomy shelf for
larger displays in the cabinet itself.
Both machines boasted a candy saving receptacle
which prevented candy from spilling from the vending
chute and sanitary delivery device. A burglar proof trap
door, made of extra heavy metal, closed the larger
merchandise chute to would be pilferers They featured
a coin slot with the latest slug proof design, improved
mercury electric switch for positive action in the
operation of the claw, and an automatic counter to tally
the number of plays.
The mechanism is a miniature model of an excavating
IRON CLAW MODEL 6
IRON CLAW JUNIOR
Advertised in their day as "... a sensational earner
and easily... the leader of all coin operated amusement
devices," the IRON CLAW proved to be a popular draw
in arcades and carnivals with alJ folks, young and old.
Exhibit Supply Company of Chicago, Illinois, produced
the Exhibit IRON CLAW JUNIOR and IRON CLAW
MODEL G. These were basically digger type machines
first manufactured in the '20a The price, when sold
new, ranged from $150 to $275 for the Model GI RON
CLAW. Produced primarily in 5$ denominations, they
were later converted by some operators to dime
machines
Exhibit Supply Co. touted the cabinet of the Model G
as designed by one of the country's foremost artists to
be beautiful enough to gain acceptance in the finest
locations. It was 70 inches tall, 24 inches wide and 22
inches deep and a "Show-Case Base," which displayed
larger merchandise, was offered as a custom addition.
The machine's metal parts were chromium plated and
highly polished to be more visible. A plate glass mirror
the full length of the back of the upper cabinet
reflected the merchandise available for a nickel. The
cash box opened from the front on this model, allowing
the meter to be visible and the machine to occupy a
smaller space.
The IRON CLAW JUNIOR was also "exclusively
designed" in a silver oak finish with chromium plated
ornaments. Separate doors opened both the upper
and lower cabinets individually, which together

construction machine that worked on the same prin
ciple. The claw was multi-adjustable; allowing a forward
and backward, as well as right to left, movement
determined by a Locator Wheel positioned by the
player. The claw was operated by a small, 110 volt
motor, and the motor burning out was about the only
problem with the device, other than coin jama These
machines were easy to maintain, and almost all working
parts were made from interchangeable die castings.
The claw would be positioned to grab for favors
placed in the device by the operator. A lot of cheap
prizes, known in the industry as"slum," were displayed
amongst a few enticing items, such as wrist watches,
pocket watches, lighters, pocket knives, and cameras.
Operators found they could make more money when
they offered a few better prizes, especially ones kids
were not supposed to have. Many a young boy lost a
handful of nickels trying to grab at a fancy pocket knife.
Sometimes the better prizes were banded together, or
additionally weighted, so the claw would not be able to
pick them up for the unsuspecting patron.
The player would first pick the prize he wanted from
the merchandise displayed in the cabinet. He would
then turn the Locator Wheel on the front of the cabinet
to show about where the claw would drop, right, center
or left, as indicated by the arrow on the indicator. The
player would then put the nickel in the slot that started
the machine. The claw automatically turned to the
chosen position, dropped down and grabbed at a prize,
if you were lucky, and a few pieces of candy. Then the
claw raised, swung back over the opening, and dropped
the contents into the chute to be delivered to the
player. The entire operation took about 10 seconds
and IRON CLAWS were touted to be able to make 300
an hour.
Found mostly in arcades, the elegant styling of these
machines also made them popular in hotel lobbies,
restaurants, any place an amusement device would be
played by the public They were advertised by Exhibit
Supply Company as "Built up to a standard, not down
to a price!" Primarily considered a gambling machine,
the elegant cabinets fit in very well with an already
established collection of slot machines
