Claim 11

Dependent Claim 83 words

The breathing apparatus of claim 1, wherein said inner cylinder and said main body have a plurality of grooves divided into at least first and second groups of grooves and a mating stop member, said first group of grooves having grooves which extend circumferentially with respect to said inner cylinder permitting rotational movement of said inner cylinder with respect to said main body, said stop member mating with said grooves to control the extent of rotational movement, said rotational movement permitting percussive exercising.

Claim 12

Dependent Claim 62 words

The breathing apparatus of claim 10, wherein said second group of grooves extend generally longitudinally with respect to said inner cylinder permitting longitudinal movement of said inner cylinder with respect to said main body, said stop member mating with at least one groove of said second set of grooves to control the extent of longitudinal movement, said longitudinal movement permitting resistive exercising.

Claim 13

Dependent Claim 99 words

The breathing apparatus of claim 1, wherein said inner cylinder includes a plurality of second openings; said plurality of second openings each have different diameters; at least one of said second openings being adapted to mate with said at least one first opening to vary resistance to inhaling and exhaling, said inner cylinder being longitudinally movable with respect to said main body to further vary resistance by sliding said at least one of said second openings with respect to said first opening to partially open and close said first and second openings as a result of inhaling and exhaling.

Claim 14

Dependent Claim 52 words

The breathing apparatus of claim 1, further including a stop means adapted to align said first slot and said second slot and to permit limited rotation of said inner cylinder with respect to said main body to allow percussive exercising; said first and second openings being closed when said grooves are aligned.

Claim 15

Dependent Claim 28 words

The breathing apparatus of claim 1, wherein said inner cylinder has a rotation member for permitting manual rotation of said inner cylinder with respect to said main body.

Claim 16
