ball bearing mounts are disposed the cylindrical
40 shaped weight members I3—l3.
The outer ends of these weight members I3 are

At the intermediate portion of the barrel I I
an anchoring pin 20 is located and from this pin

springs 2I—2I, each of which connects at its
outer end to the adjacent end of the correspond

shaft, said shaft provided with a spiral forma
tion at its inner end, an anchor in the barrel, an
extensible coiled spring in the barrel having one
end connected to the anchor and its opposite end 35
to the spiral formation, a coiled compressible
spring on the shaft having one end connected to
the inner end portion of the shaft and its outer
end abutting the adjacent end portion of the

prising a barrel secured to a rotary structure to
project laterally therefrom, a shaft longitudinally
extending from the outer end of the barrel and
journally supported therein, a paddle on the outer 45
end of the shaft, said shaft being longitudinally
slidable in response to centrifugal force, spring
means for retracting the shaft when relieved of
centrifugal force, and means for causing rotation
of the shaft as it slides in the barrel, said means 50
for causing rotation of the shaft consisting of a
pair of closely spaced pin members disposed across
the interior of the barrel, said means for causing
rotation of the shaft further including a spiral
formation on the inner end of the shaft ridably 55
disposed between the pin members.
