2203) This looks like a tool (calculator) for telling when a given
heavenly body will cross the horizon, and in what direction. At
a guess, it is for indicating sunrise and sunset times and
locations, though it might be for something else perhaps
specific stars used for calculating latitude and longitude wit
the aid of a sextant.
It also appears to include some form of telescope -- perhaps
with eye-protecting filters if for the Sun. It might also just
display constellations to help find a specific star for
2204) Perhaps a tool for setting railroad ties at a proper right
angle to the rails -- or at least for measuring how far off
the ties are before driving the railroad spikes to lock them to
Or -- given the V bottoms, it might be for measuring the bend in
a round rod. This it would be easier to use than with the
other, because I am having difficulty imagining how it fits with
sufficient accuracy to the ties.
2205) A tool for nibbling a specific curvature in the end of a round
wooden rod. Perhaps for making a shape for a good splice when
grafting one kind of limb onto another tree or shrub.
Or -- it might be for cutting the rounded end on a broomstick.
I'm not sure whether there is sufficient clearance for that.
2206) The front frame of a mantle clock modified to serve to display
hay -- or to act as a window into a storage place for such hay,
perhaps for feeding an indoor donkey?
2207) For separating something (perhaps grain again) according to
size. Each screen is finer than the one above it, so you wind
up with layers of different fineness.
2208) Perhaps to catch embers below the grate in a coal-fired stove?
Now to see what others have suggested.
2204 It's for aligning agricultural drain tiles. The system came to
America in 1838. In 1882, more acres in Ohio were tiled than in all
previous years. If the tiles weren't well aligned, dirt would fill them.
