Hi, The design suggests to me that it may have been connected to a round
object such as a sailboat's mast. I once read about a counter balance =
device
that reduced the port/starboard sway when a boat is at anchor buy using =
a
counterbalance pendulum to create an apposing force that reduces the =
wave
energy. The rollers in the top photo suggest to me that they would allow =
the
base object to be hoisted to the upper portion of a mast increasing the
effect of the pendulum. Here is a link to some patents that describe =
this
idea. www.freepatentsonline.com/CCL-114-122.html=20
=20
 My guess, Steve Hammond

Hi Jerry and all,
=20
I put up some text and 3 more pictures of a rather unusual pendulum
(horizontal
sensing), on the web, and some very brief text relating to its other
vertical sensing
use/s.  The pendulum is essentially a hanging mass or "S-G" type.  The
aluminum
looks to be quite useful for a variety of seismometer =
setups....without...as
much
material being used.  Fun stuff!  See:
