weighted arms are attached to the free end of the long arms making a
double row of weights.
long arms lift the short arms by temporarily drooping at the three
and/or nine o'clock positions.
are latches holding weights so that they are released at the right
torque is output from the middle of the long arm.
mechanism components are shown on the four main drawings and can be
measured according to Bessler's “Shoe Scale”.
devices are simple enough to be built by a moderately skilled
teenager with simple 1700's components and hand tools.
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.
one-way wheel: Short arm axle pivots are parallel to the main axle.
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
one-way wheel: Has one spring per arm set.
one-way wheel: When the weight is lifted the short arm may rotate as
much as one hundred eighty degrees.
one-way wheel: Weights appear to move backward in relation to the
wheel while falling.

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.
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.
two-way wheel: The long arms are hinged on the center wooden axle
shaft and extend radially.
eight and number twelve could easily be connected somewhat like the
lazy tongs. The
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
two-way wheel: has twice the rim torque as the one way wheel per
pound of weights.
two-way wheel: has two springs per arm set.
loud banging reported in the two-way wheel was NOT the driving
system of weights may be in constant tension.
on the falling side bobble while on the falling side of the wheel.
“toys page” has timing and linkage information.
angles at the top of figure B on the MT Toy's Page are important.
Wheel or Both:
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.
lift arms a small amount on the rising side of the wheel.
is a ratchet device that is used to lift or catch the small arm
device that lifts the short arm may not be permanently attached.
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.
kind of squeeze play is employed. (See below)
Sure Of but Curious:
