<p>PURPOSE:To make a whole device compact and obtain a high output, by mounting two vertical windmills with spaces around windmill shafts and interlaying the vanes of the windmills between each other not to interfere with each other. CONSTITUTION:Two windmills 1, 1a, each of which has three vanes 3 or 3a at regular intervals, are mounted with spaces 4, 4a around windmill shafts 2, 2a. The vanes of one windmill are interposed between those of the other. As a result, a whole device is made compact and a high output is obtained. Driving bevel gears 6, 6a are mounted near the lower ends of the windmill shafts 2, 2a. Driven bevel gears 9, 9a, which are engaged with the driving gears 6, 6a are mounted on a single horizontal shaft 7 so that the windmills 1, 1a are smoothly rotated together at the same speed in the opposite directions as their vanes 3, 3a do not interfere with each other.</p> |
