US Patent:

Filed:
Jan 27, 1999
Appl. No.:
9/239107
Inventors:
Michael R. Coppola - Boonton NJ
International Classification:
G10D 1302
US Classification:

Abstract:
The present invention is a drum rim protection device designed to protect the rim of bass drums from damage when being struck by a musician. The invention comprises of two members having an outer surface, openings in their inner surfaces, one opening being holes that receives threaded rod which joins the members, the other hole being an arcuate groove sized to receive and receiving a drum rim therein. The members are joined by a pair of threaded rods which are received in a turnbuckle. The groove in each member deepens from the inner surface towards the outer surface, terminating in a cut surface to which is glued a layer of cushioning material, preferably foam rubber. The device is attached to a drum by separating the two members a distance sufficiently greater than the thickness of the drum, engaging the drum rim within the groove of the first member, engaging a second rim within the groove of the second member, and rotating the turnbuckle so that the members are pulled together and the drum is securely retained there between. The cushioning material prevents the drum rim from being scratched by the device. The members are made from a hard wood such as oak, mahogany, cherry or walnut, or of a plastic, rubber or metal.
