2272 Geiger counter?
2273 looks like it could be used as a fumigator -- bottom part appears to have
a fuel reservoir and a wick.
Where do they live? A place which has orchards? If so, that
increases the chance that it was a smudge pot as I just suggested in
what I posted.
I've never seen one, but this looks like something which would
do the job.
I sent an email to the owner of this device asking where they live and what
the grandfather did for a living, but haven't heard back yet.
The answers for the rest of them have been posted and can be seen here:
2271 looks like a simplified version of this:
2272 looks like a geiger counter
2270 is an IBM computer (you can see the logo on top); the first hard
disk drive computer, in fact. It's a 305 RAMAC HDD
2269 is a portable signal light, similar to this one
2269 looks like a hand-held signal light for sending morse code between
ships. If there's no visible emission it would have the infrared filter
2270 might be a cesium-beam atomic clock, probably being loaded as part
of the Hafele-Keating experiment.
2269- aircraft control tower light gun to signal planes with no
electrical system or that are NORDO (NO RaDiO due to failure)

prevent dust explosions rather than for use in mines -- The screen
acts as a flame arrester; air (and any firedamp/ dust present) can
pass through the mesh freely enough to support combustion, but the
holes are too fine to allow a flame to propagate through them and
ignite any firedamp outside the mesh
2274 looks like it might be a form of spider coupling used to transmit
torque from one shaft to another shaft which may be neither collinear or
parallel. (Sort of like a universal joint but not as rigid.)
