80 wheel. A vertical lever, h, with axis at i, has an elongated hole at the lower end that works over the crank-pin and as k revolves, the lever operates from side to side. The hole must be long enough for the crank-pin to reach its highest and lowest point easily. The elongated hole can be effected by extending a wire loop down from the end of the vertical lever to work on the crank-pin. The wire should be lashed with linen thread to the vertical lever and coated over with glue. An object can be used on the upper end, such as a head, a flag, etc. In the same manner, hands and feet may be extended and withdrawn, a turtle might be made to draw in head and feet and many other interesting operations, but in all of these the machinery must work easily, must not lop over against anything else and above all we must remember not to load down our kite with weight or over-balance it with undue leverage at any part of the kite.

Another way of attaching to windmill is to make the wire axle long enough to pass thru and at the back bend into a crank, Fig. 160. The lever h would work direct on this crank as it does on the crank-pin in the device with the second grooved pulley, k, Fig. 159. To make the head go up and down, use a round hole instead of the elongated ones in the vertical shaft. A loop of wire, Fig. 161, should
