Similar to the 8860 and 8865 designs, here's a very simple and
compact one:
As a carrier, have two 'beams' with 3 holes with 1.5 stud spacing
(i.e. 2 standard beams, any size, and a 1-beam between them)
with 5 studs of space between them. In the center, put a
12-axle such that it sticks out 4 on one side and 1 on the other,
while an 8-gear, a 16-gear, and another 8-gear are centered
in the 5-wide space. On the longer end, you have 3 studs
worth of axle for the shifter handle.
On the outside holes, put (diagonally symmetric) 2 axles,
length 8 or more, in such a way that they won't shift,
with a 16 gear, one space, 2 8-gears, and another space
on one side and reverse (sp,8,8,16,sp) on the other.
Between these input/output axles, you now have ratios
of 4,1,1/4. Using 24/8 gears rather than the above,
you get 9,1,1/9; with 24/16, you get 9/4,1,4/9, which may be
the best setup. This symmetric setup may be extendable,
but it will get rather large, while having the center axle
change ratios on both sides makes the design sturdier
and close ratios generally easier.
