Two, one either side of the crank, may have been secured to the engine
frame just inside the deckhouse walls. Two were certainly outboard,
one on each side, fastened to the topsides, as shown in Marestier's
sketch of the wheel construction. The axle, probably square in cross
section, turned only at the bearings and wrist pin. It may have been
cast in two parts, each with a crank arm, and then joined by the wrist
pin, after the latter had been turned.
The wheels, shown in much detail in Marestier's sketches of the
engine, had flanged hubs to which the pivoted arms or spokes were
bolted. The fixed arms were integral parts of the outer hubs. The
inner flanges were cast with the hubs. To fold the blades, the fixed
arms were brought parallel to the rail, then the chain span between
each pair of the pivoted blades on top of the wheel was disconnected
and a pair of the blades, each way, were dropped on top of the fixed
arms, or blades, and lashed there. The wheel was then given a
half-revolution and the process repeated. The wheel could then have
been unshipped from the hub by sliding it off the square shaft end
after removing, let us suppose, a bolt or pin in the hub. Some
writers, like Collins, refer to a "jointed" or "hinged" axle, but
Marestier makes no mention of such an arrangement; indeed, his sketch
makes a "broken" axle impractical. The wheels could have been removed
from the axle and lifted aboard by use of tackles from the main yard
ends, or from a fore spencer gaff if it were made long enough.
However, as stated in the Russian description, the pivoted blades were
removed and stowed aboard, leaving only the two fixed arms in a
horizontal position outboard. This is a far more convenient treatment
than unshipping the whole wheel, as might be supposed from logbook
mention of "shipping" or "unshipping" the wheels.
There remain some other matters to be explored. The ship was fitted
with 32 passenger berths in staterooms. The passenger accommodations
for first class passengers in the early (1820-1830) packets were aft,
on the lower deck. The berths would have been about 6 feet 2 inches
long, and 2-1/2 feet wide. With berths placed athwartships and
allowing for cabin bulkheads, there would have remained a space at
least 10 to 12 feet wide down the centerline of the ship. This space
would have provided space for a mess table and a lounge area. Each
stateroom would then have been about 7 feet long fore and
