Abstract
The present invention relates to an improved wind-bell of the seated type comprising of at least two or more blades, a central rotating axle, a striking bar, sound-producing bars, dragging means, a frame and a base plate. The blades are connected to the central rotating axle which is inserted through a bore at the center of the frame into a hollow stationary post secured to the base plate. A plurality of sound-producing bars are provided with hooks on both ends thereof, with hooks on the upper ends hooking at an annular support and hooks on the lower ends hooking at retaining rings provided on the base plate. The striking bar is mounted at a suitable location on the central rotating axle. In use, wind force drives the blades to rotate which, in turn, rotates the central rotating axle, making the striking bar provided thereon rotate with it, thereby striking the sound-producing bars to produce tuneful music sounds. Dragging means is provided in the hollow stationary post, such that the rate of rotation of the blades is regulated by the frictional drag generated between a friction block on the top end of the dragging means and the bottom end of the central rotating axle, and thereby …
