Abstract

735,111. Wind-motors. BAUER, R. April 24, 1952, No. 10389/52. Class 110(3). [Also in Group XXIV] A high-speed windmill motor comprises elastic spring suspension means for the rotor yieldable to forces acting on the rotor transverse to its rotational axis. The motor may comprise a two-bladed wind-wheel 1, Fig. 1, connected to its shaft 2 by spring bars 3 or a single overhung spring bar shaft. In a modification, the windwheel consists of a single blade which is balanced by a counterweight and supported on an overhung spring-bar shaft which is pivoted on a tower and directed obliquely upwards.. In Fig. 6, the shaft, which in this case may be rigid, is mounted in a housing 24 pivoted to the tower and supported by a compression spring 27. In a second modification, Fig. 8, the blade 7 is held in the starting position, as shown in full lines, by a spring 10 and as soon as it turns it is urged by a weight 9 into the operative position shown in broken lines. In a third modification, Fig. 9, the blade is pivoted at 8 and 12, as shown, and is secured to the shaft by means 13 comprising a spring mounted in telescopically sliding housings. In a fourth modification, the main blade is flanked by a leading blade which extends the full length or part of the length of the main blade. In a fifth modification, the leading blade carries a weight and is connected to the main blade by a spring, whereby the leading blade acts as a centrifugal governor. In a further modification, Fig. 16, the leading blade 17 is moved longitudinally under centrifugal action against the action of a compression spring 31 and at the same time is rotated about its axis by means of a pin 30 engaging a slot 20.
