Answers:


2467. A Boettger and Wittig Demagnetizer, a watch was placed inside of the core and the slide was then moved in and out to change the polarity of the magnet, as described in patent number 699863:
The slide and comb thereon constitute a pole changer, and in practice the same is actuated to cause frequent reverses of the direction of current that goes through the electromagnet. A magnetized watch, tool, or other device is placed in the hollow core of the electromagnet… the pole changer is operated to effect its function… the result being demagnetization of said device.






































2468. A piston groove cleaner, a similar one can be seen in use in Figure 8 on this page:

  1. 2467 looks like a device for demonstrating the effects of an inductivity in an electrical circuit.
    maybe also the effects of different cores for the coil.
    The drawer is just a kind of mechanical inverter.

    Up to now no ideas for the other devices.
    2468 seems to be rather a blade than a screwdriver.
    2467 could be a sprung latch of a mortise like lock
    2469 are blinding goggles, but i dont know for wich use.

  3. 2472 Could this be some kind of a card shoe? You put a deck of cards in the red part and the mechanism deals single cards from the bottom of the deck?

  4. 2469 Old welding goggles?

  5. 2467 The light bulb limits current and the slidey bit is a sort of commutator which coverts DC to AC causing an expanding & collapsing magnetic field around the coil. Could its purpose be for magnetizing or demagnetizing tools or some other object?
