the reserve compartment will be delivered to the lower
compartment until it is full. When the reserve has been
filled up to capacity, the excess coins overflow into the
take. Because this continuous fill operation is con
trolled completely by the force of gravity, incomplete
or out of sequence filling is impossible — gravity
always works.
While the body of the jackpot assembly has remained
almost unchanged since its introduction, the linkages
which operate its mechanism have undergone contin
ued simplification and improvement.
On the original Chiefs, the resetting of the jackpot
and the withdrawl and release of the reserve fingers
was accomplished by«a separate linkage located on
the left of the mechanism and attached directly to the
clock With each reset stroke, this linkage arm moves
forward and, if the jackpot door is open, engages a
wheel on the end of the door control camshaft and
rotates it 90°, thus closing the door. If the door is
already closed, no rotation takes place. At the end of
The only adjustment needed on this reset linkage is to
ensure that the reserve fingers are fully withdrawn
before being released by the pawl, this being achieved
by bending the
pawl
release tab up or down as
necessary.
The jackpot trip lever and linkage is located
on the right side of the mechanism immedi
ately above the slide stack Mounted with
slotted holes for adjustment purposes, this
trip lever rests against the end of the top
slide and is pulled downward by a spring when the top
slide is pulled. The end of the lever then strikes a wheel
on the right end of the door control camshaft, rotating it
90° and allowing the jackpot to dump. This lever should
-be adjusted so that it receives maximum uplift when
the slides reset, but also meets the pin on the camshaft
wheel at the approximate center of its edge when
required to trip the jackpot. Slide the lever to and fro
until porper lift and engagement is obtained, then
tighten the mounting screws firmly.

rearward. When the fingers have been fully withdrawn,

resulting in a minimal tube payout, as opposed to the
other makes, which pull all the slides and give the
maximum tube payout in addition to the jackpot.
Later Chiefs eliminated the reset linkage on the left
side of the jackpot and integrated it with the trip
linkage on the right side. This has been done by using
the upward motion of the trip lever during slide reset to
move a camshaft resetting lever now located on the
right. A small roller pin projecting from the side of the
trip lever engages a ramp arm on the reset lever, and

should be adjusted so that it first lifts the lever until the
camshaft has rotated a full 90°, and then continues its
upward motion without binding against the now immov
able reset lever.
The reserve fingers are also controlled by the roller
pin, and should retract fully from the rear face of the
jackpot compartment as the slides reset. When the
slides are released on the fifth click, the reserve
fingers should be fully released and allowed to come
forward against the jackpot glass, even if the slides do
not pull far enough for a payout. This action can be
obtained by bending the ramp lever of the reserve
finger linkage so that more or less movement is
achieved where the lever engages the roller pin.
The only remaining adjustment is that of the
jackpot/front casting interface. Attached to
the mechanism frame by one screw at
either side of its base and a third screw at
its upper left side, the entire jackpot assem
bly can be rocked slightly forward or backward to
regulate the gap and angle between the jackpot glass
and the opening in the front casting. This adjustment is
seldom necessary and need only be disturbed when
the mechanism is being fitted to a new or rebuilt
cabinet.
After all adjustments have been correctly carried
out, "Hitting the Jackpot" may still be up to the Fates—
but proper jackpot operation will be guaranteed.
