ABSTRACT:
A device for setting the tension of a skin, particularly one used in a musical instrument, such as a kettledrum. The device includes a freely-suspended multi-part linkage for vertically displacing a tensioning star, wherein the linkage has two parts connected through a pivot. Each of these link parts has first and second ends, where the first and second ends of the first and second link parts respectively form first and second ends of the entire linkage. The pivot lies inward on the first and second link parts of the second and first ends of the first and second link parts, respectively. Furthermore, the second link part bears, at a first predefined location thereon, such as proximate the second end thereof and via a contact face located thereat, against an adjustment cam. A coupling pin is connected to the second link part at a second predefined location intermediate the point where the pivot is connected to this link part and the first predefined location. The coupling pin, in turn, is connected to and vertically moves the tensioning star to increase or decrease the tension of the skin based on direction and distance through which the pin moves. Through vertical movement of adjusting end, the tensioning star is vertically moved in such a manner that tension is evenly imparted to the skin, which, in turn, reduces objectionable vibrations produced by the instrument and hence improves its tonal quality.
