Abstract
Abstract A drum practice pad having a solid base portion of relatively hard material into which a circular pad of soft gum rubber is recessed to a depth approximately equal to one-half of the thickness of said rubber, said base portion being of a diameter to permit it to fit on a head of a drum inside the rim thereof but without touching the rim, thereby to permit said base to be supported on the head of the drum or independently on a drum stand or other support. A drummer may practice with drumsticks on that side of the base portion into which said rubber pad is recessed or with drum brushes on the opposite side.

A drum practice pad capable of being supported on the head of a drum or independently on a drum stand or other support, comprising: a solid base portion substantially in the form of a flat circular cylinder and made of relatively hard material, the diameter of said base portion being substantially equal to the inner diameter of said drumhead to permit said base portion to be seated on said drumhead inside the rim thereof without touching said rim, the height of said base portion being a small fraction of its diameter, the upper and lower surfaces of said base portion being normal to its axis and defining playing surfaces for practicing a drum type of musical instrument, and a circular pad of relatively soft resilient material, said soft resilient pad being of a diameter less than said diameter of said base portion, said soft resilient pad being of a uniform thickness substantially less than said height of said base portion, said soft resilient pad being recessed into one of said playing surfaces of said base portion to a depth approximately equal to one-half of the thickness of said soft resilient pad, whereby a drummer may practice with drumsticks on that side of said drum practice pad into which said soft resilient pad is recessed or by turning said practice pad over, with drum brushes on the opposite side.
