ding, and the power may
be transmitted below, or to the top of a stand specially erected
for the purpose. It is a good plan to visit some of the
second-hand machinery dealers and get four gears, a pulley and a
shaft. Gears about 5 in. in diameter and beveled will be required.
Adjust the first pair of the beveled gears as at F and G. If the
wheel shaft is metal, the gear may be set-screwed to the shaft, or
keyed to it. If the shaft is hardwood, it will be necessary to
arrange for a special connection. The shaft may be wrapped with
sheet metal and this metal fastened on with screws. Then the gear
may be attached by passing a pin through the set-screw hole and
through the shaft. The upright shaft like the wheel shaft is best
when of metal. This shaft is shown extending from the gear, G, to
a point below. The object is to have the shaft reach to the point
where the power is received for the service below. The shaft is
shown cut off at K. Passing to Fig. 3 the shaft is again taken up
at L. It now passes through the arrangement shown, which device is
rigged up to hold the shaft and delivery wheel P in place. This
shaft should also be metal. Secure the beveled gears M and N as
shown. These transmit the power from the upright shaft to the
lower horizontal shaft. Provide the wheel or pulley, P, with the
necessary belt to carry the power from this shaft to the point of
use.

The tail board of the windmill is illustrated in Fig. 4. A good
way to make this board is to use a section of thin lumber and
attach it to the rear upright, E of Fig. 2. This may be done by
boring a hole in the upright and inserting the shaft of the
tail-piece. In Fig. 4 is also shown the process of fastening a
gear, R, to the shaft. The set screws enter the hub from the two
sides and the points are pressed upon

the shaft, thus holding the gear firmly in place. The platform for
the entire wheel device is shown in Fig. 5. The X-piece S is bored
through in the middle and the upright shaft passes through. The
tin run-way or ring is marked T, and the X-piece very readily
revolves in this ring, whenever the wind alters and causes the
wheel's position to change. The ring and ring base are secured to
the platform, U. The latter is made of boards nailed to the
timbers of the staging for supporting the mill. This staging is
shown in Fig. 6, in a sectional view. The ring with its X-piece is
marked V, the X-piece is marked W, and the base
