3020 Another planinmeter. We had one a while ago. Used to measure the
area of an arbitrary closed figure on a flat surface.
3023 Go/NoGo thickness gauge. (guess)
3024 Plane for shaping the end of a wooden cart axle. This is a guess,
so I have no idea what the specific name would be.

3019 looks to be a limited-range pressure/vacuum gauge, perhaps for a
spirits still, measuring only +-3in. of mercury. It's spout could be
pushed into a grommetted bung hole or the end of a rubber tube to take
3020 YAP. (yet another planimeter), but this one specifically a
planimeter in the form of a fixed-radius compass.
3021 broken keys exactor set.
3022 A sump cover for a rain spout?
3023 A spoke wrench?
3024 large round tenoner... maybe for axles, but maybe 'tree' making.
Some more wild guesses.
3019. I think this could be a vacuum gauge for use with a steam powered
engine. Very likely maritime.
3022. A trivet arrangement which clamps to the flue/chimney of a solid fuel
burner. To keep stuff warm.
3024. A woodworkers (or bodgers) rounder, aka rotary plane. Rough shape a
bit of stock and wind this tool along it to produce a dowel or round rod.
Posting from my desk top PC in the living room, as always.
3019 looks a bit like a pitot (PEE-tow) gage. Used to read the velocity
of air or water, based on how high it pushes the liquid (mercury, most
likely) from one tube to the other. The water dept uses a pitot gage to
check the flow of fire hydrants.
3020, totally no clue. But, that sure is a nice matching case.
3021, the handles remind me of lock picks. More likely a tooth pick set
for obsessive compulsives.
3022, no clue. Maybe for keeping a pot off the coals?
3023, bicycle spoke wrench. That, or midget valve wrench for acetylene
3024, I somehow guess it's for cutting ends on wooden logs, which are
used for early water pipes. I saw some thing resembling this at
Valentown museum, at Victor, NY.
_Modern__Blacksmithing_, 1904, chapter 4:
"When a wheel has bolts every smith knows that it will make trouble for
him if he don't get the tire back where it was."
"When bolting a wheel the tire will be out of place unless the tire has
been shrunk alike on both sides of the fellow plates. A smith used to
setting tires will be able to get the holes almost to a perfect fit."
