2206 is a clock. It requires you to know the half-life of hay.

    Posting from rec.crafts.metalworking as always.
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     navigation purposes.
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     the rails.
    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.
    Enjoy,         DoN.

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.

2203 may be some sort of planisphere, or star finder.
