O.K. Posting from rec.crafts.metalworking as always.
1001) A Tesla coil. Generates high frequency high voltage, unlike
the static generator in a previous set which generates high
There is likely to be a tube circuit inside the box to generate
the high frequency. (Of course "high frequency" is a relative
term, and it is nowhere near what can be done these days. :-)
1002) A relative of a pulley puller. I believe that this one is
intended to be used to remove the cables from automotive (and
similar) battery terminals.
The knob has a cone on the bottom which spreads the upper arms
of the hooks, thus bringing the hooks themselves closer together
to grip under the battery terminal clamp.
The flat end of the long screw presses on the center of the
terminal, thus applying the force necessary to remove the
terminal even if it has gotten rather jammed on there.
1003) This is designed to throw something. I think that the rings
are a bit small for tennis balls or for clay pidgeons, so I
would expect something like golf balls or the like. The
presence of the nets eliminates things which could simply sit in
the rings touching on all sides.
There may be some missing parts to allow it to be triggered
by pulling a cord.
1004) Hmm ... perhaps the frame to which a net is attached for
dealing with a just-caught fish. Or perhaps it would be for
controlling some domesticated animals like sheep.
1005) Strange one. Perhaps for making the skin punctures all at once
which used to be common with chicken pox vaccinations.
1006) Another intersting one. It seems that the larger holes are
marked for threads, including very uncommon ones these days.
The fractional number is the diameter of the OD of the thread,
and the integer is the number of threads per inch.
The smaller holes could be the number-sized screw diameters,
except that there appear to be integer sizes followed by sizes
1/4, 1/2, and 3/4 of the way up to the next size.
Can you tell what the material of the discs is? It looks like
zinc, which would not be durable enough for use as a gauge for
screws and drill bits.
Perhaps it is for sorting lead shot or the like, with the
numbers corresponding to the size in whatever system is used.
It could be placed over a collection of small bottles, and the
shot rolled from one disc to the next until it finally falls
through thus defining its size.
Now to see what others have guessed.

1001 Another high voltage generator, this one should have a belt inside
1002 Some type of gear puller
1004 Looks like a railroad order hoop, used to pass orders to the
engine and caboose crews without stopping.
