Spiral Wheels They Are Only Double Horizontal Wheels And Made

thus: the nave must be about six inches long, and rather thicker than
the single sort; instead of the pintle at top, make a hole for the
case to be fixed in, and two sets of spokes, one set near the top of
the nave, and the other near the bottom. At the end of each spoke cut
a groove wherein you tie the cases, there being no fell: the spokes
should not be more than two inches and a half long from the naves, so
that the wheel may not be more than eight or nine inches diameter; the
cases are placed in such a manner, that those at top play down, and
those at bottom play up; but let the third or fourth case play
horizontally. The case in the middle may begin with any of the others;
six spokes will be enough for each set, so that the wheel may consist
of 12 cases, besides that on the top: the cases six inches each.
