I'm on a Mission! What is it??

[drewdiggs]

I posted this before, but was hoping for a new set of eyes on it. Also there has been a recent discovery in introducing the small new piece that I recently found. The largest one is almost 5" in diameter and the thickness is about half of that of a Roosevelt American dime. ? Guesses are also welcome!

These look to be made of tin, which makes me thing they are relatively modern, probably dating from the 1950s - 60s.
They look to be industrial in nature, possibly part of a machine of some sort.

You can tell they were meant to go on some kind of shaft. The larger one has that tab that would go on a shaft with a keyway slot. The next smaller one would go on a shaft with a double flat cut on each side and the smaller one would go on a single flat cut shaft. They just look like something that would be part of some mechanical device and I'm not sure what that would be. ??

Looks to have a hex key hole slott in the middle which tells me they turned. If stainless, maybe used in food processing. 316 may be stamped on them if that's the case. Send something hard next time.

Sorry I can’t help with the ID. Welcome to tnet from Niagara Falls.

From old 8mm tapes.

A few random thoughts - maybe they might help?
Whatever these are, I agree the indexing key probably means they went on a shaft.
Interesting, each size has a different style indexing key. Hum...?

They are also light weight -- possibly that's an essential clue? (Why spend the extra labor to cut out the wedges if not to save weight?)
If this is tin or aluminum, I'm not sure if any money is saved in raw material, even if you account for the recycled scrap (i.e., the wedges themselves, once punched out).
In other words, why not just make a solid disk with a central notched or keyed hole? (Perhaps this is to provide a visual indication..?)

Regardless of size, there are (8) wedges to each wheel. Any reason for this?? Hum...?
I've been working on the assumption that the spokes are intended as a material carrier while in-motion. (Sort of like the cassette tape and film ideas already presented.)
However, any chance the materials go "through" the wedge openings? (Seems unreasonable if the mystery material to be held or transported by this object is subject to cuts or abrasions, etc..)

The mid-size design does not have tapered spokes, but the other two do.
Not sure if that means anything - it's just an observation.

Do we know the exact diameters of each disk?
I'm just wondering if they go up in size by an "obvious" factor... maybe the square root of 2, or something related to an aperture value, etc..
Are there in-between (or larger, smaller) sizes "missing", and not yet unearthed?

Compared to the spoke diameter, the thickness of the outside circumference is not very substantial.
This leads me to conclude that if this device is a carrier, or separator, for a material to be transported (unwound, etc..), whatever that is must not be very heavy (else that measurement would be more substantial).

Maybe the indexing keys are to prevent incorrect association with an end device, designed to accept a wide range of attachments.
For example, old-time screw-in fuses had slightly different diameters, threads, or electrode depths to prevent inserting the wrong value fuse into a fusebox circuit.
Something along those lines.... does the keyed index here perform a similar "preventative" function, or it is just coincidental?

I do like the idea of a cassette tape wheel, (audio, film, etc...) but all the ones I'm familiar with do not have centers like this.
And in the case of audio cassette tapes, those are usually plastic, not metal (and don't look like this anyway.)

That was my first guess, but then I remembered that the largest one is only around 5", so the smallest one in that photo is probably only an inch or so.

 

[drewdiggs]

I'm adding the sizes and an image of the newest piece found that seems to match up perfectly with the smallest of the three. The new piece is very very thin,..and I don't know yet if they are tin or stainless steel,..but there are no markings on them whatsoever. I appreciate all your input and everyone else's.,..I've found many of the medium sized ones(maybe 10)! two of the large and only one of the small and of course the new accessory to the small one.

In manufacturing a part it is very doubtful they will stamp the condition of the stainless on the part it will be on the blue print M'trl, 316.

Dose the material have a memory ? meaning if you bend it a little does it spring back.

 

[drewdiggs]

No memory. I straightened them with my hands and pliers.
