Drum beater ball

Claim 2

A drum engaging-impact system for providing a first drum membrane engagement and impact followed by an automatic second impact comprising: a drum engaging device including; a casing surrounding a relatively long chamber therein having an inner surface and a drum engaging surface at one end of said chamber; a freely movable weighted body within said chamber, freely movable therein, said body having an exterior surface in contact with said inner surface; said exterior surface of said body being generally contiguously spaced from said inner surface of said casing; and said chamber having a rear surface and a forward surface positioned behind said drum engaging surface; said body having a rear body surface engageable with said chamber rear surface when said device is initially accelerated and a front body surface engageable with said chamber forward surface after a relatively short time of said device engaging a drum surface, thereby providing second impact.

Claim 3

A drum engaging-impact system as set forth in claim 1, wherein: said casing including means for varying the length of movement of s id body within said chamber thereby varying the timing of the engagement of said body and said forward surface after said device engages a drum surface to provide second impact.

Claim 4

A drum engaging-impact system as set forth in claim 2, wherein: a means to replace said interior body with a body of a different weight.

Claim 5

In combination with a drum having a membrane and including said drum engaging device and means structually connected to said drum engaging device for moving said drum engaging device into contact with said membrane, the improvement wherein said device comprises: a drum engaging device including a casing surrounding a relatively long chamber therein having an inner surface and a drum engaging surface at one end of said chamber; a freely movable weighed body within said chamber, freely movable therein, said body having an exterior surface in contact with said inner surface; said exterior surface of said body being generally contiguously spaced from said inner surface of said casing; and said chamber having a rear surface and a forward surface positioned behind said drum engaging surface; said body having a rear body surface engageable with said chamber rear surface when said device is initially accelerated and a front body surface engageable when said chamber forward surface after relatively short time of said device engaging a drum surface; said casing including means for varying the length of movement of said body within said chamber thereby varying the time of the engagement of said body and set forward surface after said device engages the drum; and a means to replace an interior body with the body of a different weight, whereby said weighed body of said drum engaging device provide initial and secondary impact upon said drum.

Claim 6

In combination with a drum having a membrane and including said drum engaging device and means structually connected to said drum engaging device for moving said drum engaging device into contact with said membrane, the improvement wherein said device comprises: a drum engaging device including a casing surrounding a relatively long chamber therein having an inner surface and a drum engaging surface at one end of said chamber; a freely movable weighed body within said chamber, freely movable therein, said body having an exterior surface in contact with said inner surface; said exterior surface of said body being generally contiguously spaced from said inner surface of said casing; and said chamber having a rear surface and a forward surface positioned behind said drum engaging surface; said body having a rear body surface engageable with said chamber rear surface when said device is initially accelerated and a front body surface engageable when said chamber forward surface after relatively short time of said device engaging a drum surface; said casing including means for varying the length of movement of said body within said chamber thereby varying the time of the engagement of said body and set forward surface after said device engages the drum; and a means to replace an interior body with the body of a different weight, whereby said weighed body of said drum engaging device provide initial and secondary impact upon said drum.

Claim 9

The method of claim 5 wherein said movable body is interchangeable with movable bodies of a different weight.

Claim 10

The method of claim 5 wherein said chamber includes adjusting means for adjusting the length of travel of said movable body within said drum engaging device, whereby the time delay between said initial and subsequent impact is adjustable.
