ABSTRACT:
A drum having hidden, drum head tensioning features. The drum features a drum head assembly being positioned within a drum body. The drum head assembly includes a mounting frame having a mounting ring being loosely fitted within the drum body. A number of mounting brackets are affixed at spaced apart locations to the interior of the mounting ring. A number of first threaded fasteners are threadably engaged with the mounting ring and extend radially outward therefrom so as to selectively press against, and grip, the drum body. A number of second threaded fasteners extend upwardly from the mounting brackets. A drum head is positioned upon the mounting frame so as to cover the top of the mounting ring and to extend downwardly between the mounting ring and the drum body. A retaining band clamps the drum head against the mounting ring. The retaining band has an elongated strip extending snugly over the drum head and extending around the bottom of the mounting ring. The retaining band also has opposed ends that are turned inwardly so as to form a pair of spaced-apart fins that extend through the notch in the mounting frame. A third threaded fastener connects the fins for selectively drawing the fins toward one another and varying the tightness of the band around the mounting ring and drum head. A tensioning ring is slidably positioned within the top of the mounting ring and is positioned atop the second threaded fasteners whereby tightening the second threaded fasteners selectively raises the tensioning ring to tighten the drum head.
