O.K. It is for *solid* rubber tires -- not the inflatable ones.
And the one in the puzzle is backwards from the one in the patent.

I wonder whether it works better to have two of them in use at
once?

We generally use two tools to seat solid tires on wheelchair rims,
but that gadget looks like a heckuva lot better than what we use.

We have a commercial rig to do it by rolling it around the
circumference between the tire and rim. I think it's even more
difficult to use, especially on molded plastic wheels with the
truncated pyramid-shaped solids.

So called snap on tires can be a cast-iron SOB to mount.

I can clearly remember mounting solid rubber tires on cars without
any problems or tools. I did this about 70 years ago, on model
cars. The tires were about 1/4 to 1/2 inch diameter. HTH.
I saw a display of solid tires (No Flat) today at The Cutters Edge
