2828. Sent in by someone who would like to find the purpose of this device:

The owner's description:
The part at the top is an eyepiece.
It says Pat. Pending on the bottom, no Patent Number.
There is a motor inside that runs.
The knob on the side locks the cartridge to the body of the machine.
The thee disks have a hole in the center, very small and difficult to see, they all have marks on them, two lines, three lines etc.
The center cartridge contacts the motor wheel inside the housing and spins a disk. The spindles also have marks on them.
It does not have a light source.
Received from a widow of a river boat captain

2827. This is a woodworker's bench dog, it was pounded into a workbench and would have kept a workpiece in position during planing, sawing, etc., patent number 941,816:

2831. Not 100% sure on this one but it looks similar to a Moqui disk, which has an iron shell and a sandstone interior:

An update from last week:
2824. This is a rake that is missing its tines, several people had suggested this answer so I asked the owner to take another look at this tool and they confirmed that there are broken tines on it:

  1. 2829 a Tanto fighting knive?
    2830 a tool for smoothing surfaces.
    2831 a used cannon ball?
    2832 a miner's lamp?

  2. 2829 - Knife with a tanto style grind to the blade. In theory, they are better at puncturing armor, most folks buy them because they "look cool" - could be any one of hundreds of makers

  3. >2829 a Tanto fighting knive?
    >2830 a tool for smoothing surfaces.

    These two are correct

    >2831 a used cannon ball?

    Not sure about this one

    >2832 a miner's lamp?

    It wasn't for use by miners

  4. 2828 looks like it's for use in the textile industry? Some kind of thread inspector?

  5. 2828 Looks like a pice of a vinyl disk cutter,
