I had an idea about the above comment of Bessler's while considering something unrelated to it. My current build has one mechanism and I was considering how, in a future build, I would fit five mechanisms onto the face of the wheel and realised that it would be easier use the other side or face of the wheel as well. Then I fell to wondering if that's how Bessler did it.
I have always assumed that his wheel consisted of two discs firmly connected together with all the mechanisms installed between them, but in fact it would be much easier to build the whole thing on a single disc, using each side. This would explain the need to cover the two faces of the wheel with oil cloth. I thought it strange how the reports described the look of the wheel and could not see why he needed oilcloth to cover the sides, if two discs were underneath and therefore covering the insides. But in fact a simple frame attached to the single central disc would suffice to support the oilcloth, or the thin deals described in another report.
Then we come to the above quote; the word used for 'rims' is 'Felgen'. There is no other possible translation, however 'rims', these days, in relation to wheels are the outer edges of a wheel, holding the tire (tyre). They make up the outer circular design of the wheel on which the inside edge of the tire/tyre is mounted. Before rubber was invented, the first versions of tires were simply bands of iron that fitted around wooden wheels to prevent wear and tear. In the 1st millennium BC an iron rim was introduced around the wooden wheels of chariots.
So when Bessler says it looks like a wheel but it has no rim, he means that it can be described as a wheel but it wouldn't be any use as one because it has no rim or tire/tyre.
Note - Apparently the word 'rim' relates to Old Norse, 'rime, rimi, a raised strip of land, ridge'.
And from the online etymylogical dictionary - 'tire (n.) late 15c., "iron rim of a carriage wheel," probably from tire "equipment, dress, covering" (c.1300), a shortened form of attire. The notion is of the tire as the dressing of the wheel. The original spelling was tyre, which had shifted to tire in 17c.-18c., but since early 19c. tyre has been revived in Great Britain and become standard there. Rubber ones, for bicycles (later automobiles) are from 1870s.
