It appears that the spoked wheel concept was an attempt to reduce the weight of the unit, vibration and posssibly noise while in use. We can only surmise that it only acheived the first one, I can see that using the bags of the era would have put some serious strain on the outer rim resulting in premature failure of the spoke system.
As far as how it was mounted, it appears that a tubular "L" bracket with a flange on the wall end and what looks like a pipe flange on the platform center. This makes me how they delt with a lath and plaster wall, as I would think that it would only stay up on either a wood sheathed or masonary wall.
