Both
Wheels:
Short
weighted arms are attached to the free end of the long arms making a
double row of weights.
The
long arms lift the short arms by temporarily drooping at the three
and/or nine o'clock positions.
There
are latches holding weights so that they are released at the right
time.
Lifting
torque is output from the middle of the long arm.
Internal
mechanism components are shown on the four main drawings and can be
measured according to Bessler's “Shoe Scale”.
These
devices are simple enough to be built by a moderately skilled
teenager with simple 1700's components and hand tools.
One-Way
Wheel:
The
one-way wheel: The weights are lifted one at a time resulting in an
imbalance from the three to six o'clock positions. For at least
half of the wheels rotation they freely pivot like a plum bob.
The
one-way wheel: Short arm axle pivots are parallel to the main axle.
The
one-way wheel: Long arms are hinged at the rim and extend to the
other rim and likely curved to reach one hundred and eighty degrees
or more.
The
one-way wheel: Has one spring per arm set.
The
one-way wheel: When the weight is lifted the short arm may rotate as
much as one hundred eighty degrees.
The
one-way wheel: Weights appear to move backward in relation to the
wheel while falling.

Two-Way
Wheel:
The
two-way wheel: The weights are lifted as pairs a little before the
top and bottom of rotation. The top weight is snapped up quickly
and the bottom, maybe a little slower.
The
two-way wheel: short arms have pivots that are tangential to the
main axle, effectively moving the weights straight in and out in
relation to the main axle.
The
two-way wheel: The long arms are hinged on the center wooden axle
shaft and extend radially.
Number
eight and number twelve could easily be connected somewhat like the
lazy tongs. The
dog creeps
through the twelve hoop and is rewarded with pats on his paws by the
stiff fops. The stiff fops may be the locks that hold the weights
in place
The
two-way wheel: has twice the rim torque as the one way wheel per
pound of weights.
The
two-way wheel: has two springs per arm set.
The
loud banging reported in the two-way wheel was NOT the driving
force.
The
system of weights may be in constant tension.
Weights
on the falling side bobble while on the falling side of the wheel.
The
“toys page” has timing and linkage information.
The
angles at the top of figure B on the MT Toy's Page are important.
Which
Wheel or Both:
The
center linked rods (MT fig. 25) that are pulled like a bow string is
possibly related to the lazy tongs seen in numerous MT drawings.
Probably used in a horizontal orientation.
Springs
lift arms a small amount on the rising side of the wheel.
There
is a ratchet device that is used to lift or catch the small arm
weight.
The
device that lifts the short arm may not be permanently attached.
There
is a square axle or something that acts like one with a rectangular
bracket that holds the short arm. There is a lock or block that
engages in coordination with the square axle.
Some
kind of squeeze play is employed. (See below)
Not
Sure Of but Curious:
There
are rectangular boxes hinged at the corners with an unknown
function.
Sliding
sideways is easier than actual lifting.
