These "jacks" came with some parts I bought at auction. It seems I can use them as a jack stand, but curious if anyone has a picture of what i assume is an attachment between the jack handle and jack itself. Perhaps I can fabricate something.
I would think that all you do is set the shorter piece next to a hole, install a pin, and then apply pressure on the handle to lift the car and bring the handle in all the way to the post. Hopefully it will snap in place and not hit the edge of the base.
I would think just a pin. Line up 2 holes and put the pin in and it would be like a load binder for chains only it pushes rather than pulls.
I believe those are "Jiffy-Jax" tire savers made by the Jiffy-Jack Co. They would be purchased in sets of four.
You put the jack on the outside of the wheel, under the hub. They're used during long term storage (such as putting the car up for the winter).
I would use them for their intended purpose, not as heavy duty jack stands so you can lie under the car while working on it.

So the lift was only to get the weight off the tire? They don't look very stable with that small base.
There were many different brands of tire saving jacks.
They usually have a narrow profile because they are put under the hub on the outside of the wheel, not under the axle. The lifting mechanism is designed so the wheel can be lifted or lowered quickly. You lift the wheel high enough so the tire does not touch the floor.
They are typically used for long term storage to avoid flat spots in the tire, although they were also advertised to keep tires off oily garage floors so you could use them on a daily basis if desired (probably one reason for the quick lifting mechanisms).
I would consider them safe as long as they are used for their intended purpose. As indicated earlier, they are not designed to hold the car up for mechanical work where the car could be jostled.
