with reference to fig1 the breathing apparatus of the present invention is generally shown at 10 . the breathing apparatus includes a main body 12 and an inner member 14 , which is preferably a cylindrical tube . in the illustrated embodiment , the main body 12 is also illustrated as a cylindrical tube , but it should be understood that the shape of the main body 12 could be any desired shape . further , if the breathing device does not include the percussion exercise , the inner member 14 could be any desired shape which would allow reciprocal movement with respect to the main body 12 . the breathing apparatus is made of delron , a material supplied by dupont . the main body 12 has a mouthpiece 16 attached to a flange 18 . the flange 18 is preferably angled at about 45 ° and includes a bore 20 that communicates with the interior 22 of the main body 12 . in the preferred embodiment , the mouthpiece 16 is sufficiently flexible to be stretched over flange 18 to change the angle of the mouthpiece from 45 ° to generally in line with the main body 12 . the opposite end 24 of the main body 12 is open for receipt of the inner cylinder 14 . the inner cylinder 14 has a closed end 27 and an open end 28 with the open end 28 being inserted into main body 12 . a knob 30 extends from the end 27 so that the inner cylinder 14 can be manually rotated or reciprocated within the main body 12 . in the preferred embodiment , the main body is 3 . 567 &# 34 ; long , which includes the mouthpiece 16 , and the inner cylinder is 3 . 67 &# 34 ; if the knob 30 is included . the main body and inner cylinder are made of polycarbonate or other moldable plastic , such as polyethylene . the breathing apparatus 10 is adapted for exercising a users lungs through inspiration and expiration against resistance pulsing and percussion . the apparatus 10 has two sets of openings that can be aligned to provide resistance , pulsing or percussion exercises . by rotating the inner cylinder 14 with respect to the main body 12 , the different sets of openings can be aligned and locked in position to allow for a selected exercise . in the illustrated embodiment , the main body 12 has a hole 32 and a pair of elongated openings or slots 34 and 38 which are about 180 ° apart . the inner cylinder 14 has a plurality of paired holes 42 and 43 and elongated openings or slots 44 which extend through the inner cylinder 14 . these holes 42 and 43 and slots 44 are positioned to align with the holes 32 and elongated slots 34 and 38 respectively as the inner cylinder 14 is rotated with respect to the main body 12 . when the holes 42 and 43 are aligned with the hole 32 , resistance exercises can be performed . a set of grooves 46 which correspond to the holes 42 are provided in the inner cylinder for holding the inner cylinder 14 with respect to the main body 12 . grooves 46 are adapted to receive a locking member 50 to lock the cylinder in position once an appropriate hole 42 is aligned with hole 32 . when percussive exercises are desired , the slots 34 , 38 , and 44 are aligned . a different set of grooves 48 are provided , which correspond to the slots 44 . grooves 48 extend circumferentially about the cylinder to restrict movement of the cylinder 14 and main body 12 so that only the slots are aligned for percussive exercises . as will be further described below , the grooves 48 permit limited rotational movement of cylinder 14 with respect to main body 12 . when pulsing is desired , the locking member is inserted into a longitudinally extending groove 49 , which extends along the inner cylinder . this groove allows the inner cylinder 14 to reciprocate with respect to the main body 12 . in the disclosed embodiment , the locking member 50 is a small bolt that is threaded into a threaded bore . a raised portion 51 prevents the member 50 from being threaded too far into the grooves . the bolt can be screwed into the groove as desired . it should be understood that other types of locking members could be used , such as a spring loaded detent , a fixed detent , etc . the grooves 46 , which correspond to the holes 32 and 42 , are preferably oblong and have their longitudinal axis extending parallel to the longitudinal axis of the inner cylinder 14 . preferably , the locking member 50 has a diameter that is less than the length and width of the groove 46 so that the inner cylinder can reciprocate slightly within the main body 12 . due to the movement of the inner cylinder 14 with respect to the main body 12 , the resistance against exhaling can be increased ; i . e ., the ability to exhale is further restricted , due to the shifting from the hole 43 to the hole 43 . when the user inhales , the inner cylinder 14 is pulled back into the main body 12 to shift from hole 43 to hole 42 , reducing resistance upon inhalation . it should be appreciated that by locating the holes 42 and 43 differently , the reverse could be accomplished and greater resistance could be provided when inhaling as opposed to exhaling . still further , the user can adjust the resistance to inhaling and exhaling by manually sliding the inner cylinder 14 with respect to the main body 12 . again , since the inner holes are sliding with respect to the outer hole 32 in main body 12 , the resistance is changed . in the preferred embodiment , the hole sets 42 and 43 have different diameters to provide varied resistance , depending upon whether the user is exhaling or inhaling . in the preferred embodiment , the diameters of the holes 42 are 0 . 187 &# 34 ;, 0 . 156 &# 34 ;, 0 . 125 &# 34 ; and 0 . 093 &# 34 ;; the diameters of holes 43 are 0 . 109 &# 34 ;, 0 . 093 &# 34 ;; 0 . 078 &# 34 ;, and 0 . 062 &# 34 ;; and the diameter of the hole 32 is 0 . 187 &# 34 ;. by rotating the cylinder 14 , various resistances can be selected and then automatically varied . further , in the preferred embodiment , there are grooves 46 corresponding to each hole set 42 and 43 . alignment holes 26 are provided in flange 27 . these holes 26 correspond in size to their corresponding holes . by locating the holes with the locking member 50 , the desired holes 42 and 43 are aligned . alternatively , by aligning the desired diameter hole 42 with the hole 32 , the locking member 50 can be inserted into the adjacent groove . in the disclosed embodiment , there are four ( 4 ) sets of holes 42 and 43 , four ( 4 ) grooves 46 and one hole 32 . the holes 42 and 43 are separated into two groups with each set about 180 ° apart and the hole sets in each group are about 30 ° apart . the grooves 46 are also separated into two sets with each set about 180 ° apart and the grooves in each set being about 30 ° apart . the hole sets 42 and 43 and the grooves 46 are about 90 ° apart . with the mouthpiece 16 angled at approximately 45 °, the air that escapes from hole 32 blows against the user &# 39 ; s face . this provides the user with an indication of the effort being expended and can function as an incentive to continue exhaling effectively . percussion is dependent upon grooves 48 which extend between the grooves 46 and correspond to the alignment of the inner slots 44 and the outer slots 34 . in the preferred embodiment , each groove 48 extends circumferentially about the inner cylinder through an arc which is greater than 90 °. when the locking member 50 is positioned in one of the grooves 48 , the inner cylinder 14 can be rotated with respect to the main body 12 through an arc defined by the groove ; i . e ., approximately 90 °. when the inner cylinder 14 is rotated , the slots 44 sweep by the slots 34 to rapidly open and close the slots and rapidly block and open the ingress and egress of air into and out of the breathing apparatus 10 . this rapid action causes a percussive result in the users lungs . it should be appreciated by those of ordinary skill in the art that this invention permits percussive exercising of the lungs on inhalation and exhalation . in the disclosed embodiment , the grooves 48 are positioned apart by about 180 °. each groove is adjacent the end of the slots 44 and extends circumferentially beyond the slots a slight distance to enhance the percussive effect the user receives upon use . preferably , there are two sets of slots 44 and two grooves 48 . only one set of slots 44 and grooves 48 are shown . additionally , there are preferably two sets of slots 34 on opposed sides of main body 12 . the groove 48 opposite the aligned slot 44 is the groove that receives the locking member 50 . it should be appreciated that the groove 48 adjacent the slot 44 could be used if the locking member or the slot 34 were repositioned during manufacture . in the preferred embodiment , the slots 34 and 44 are long and narrow to give increased percussive effect to the user . the disclosed slots 34 and 44 are approximately two ( 2 ) inches long and 0 . 062 inches wide . for strength , each of the slots 34 and 44 can be formed by two smaller slots positioned end to end . applicant has found that long narrow slots provide a more effective percussion of the lungs because greater volumes of air can rapidly pass through the slots , and the slots can be closed rapidly , resulting in bursts of air into the lungs . because of the burst of air , a humming noise is produced , which can also act as an incentive for increased usage . a notch 49 is provided to permit easier alignment of the slots 34 and 44 . by aligning notch 49 with locking member 50 , the slots are automatically aligned . to provide pulsing exercise , the groove 46 is aligned with locking member 50 . a smaller notch 49 is provided to facilitate proper alignment . by aligning notch 51 with locking member 50 , groove 46 is directly beneath locking member 50 and can then receive locking member 50 . groove 46 allows the inner cylinder to reciprocate with respect to the main body 12 as the user exhales . with the unit pointed up , the user exhales and the inner cylinder is raised to expose slots 44 . when slots 44 are exposed , the inner cylinder 14 drops down momentarily until pressure from the exhaled air increases in the cylinder 14 to raise it again . this repeated raising and dropping causes a pulsing effect on the lungs . to use the breathing device , the inner cylinder 14 is rotated with respect to the main body 12 to align either the holes 32 and 42 or the slots 34 and 44 or the groove 46 . if resistance exercising is desired , then the holes are aligned . if percussion is desired , then the slots are aligned . if pulsing is desired , then groove 46 is aligned . once aligned , the locking member 50 is threaded into the adjacent groove . once the desired exercise is selected , the user inhales and exhales into the mouthpiece 16 . if resistive exercising is selected , the inner cylinder 14 reciprocates within the main body 12 to automatically adjust the resistance , or the user can manually control the relative resistance by controlling the amount of reciprocal movement of the inner cylinder 14 . if percussion is selected , the inner cylinder 14 is manually rotated by the user as the user inhales and exhales . knob 30 facilitates rotation of inner cylinder 14 with respect to main body 12 . if pulsing is desired , the user uses groove 46 . with reference to fig3 a further embodiment of the present invention is shown . in this embodiment , a weight 60 is positioned in the inner cylinder 14 . the weight is illustrated as a rod , but it could be a ball , a disk attached to the flange 27 , a spring , etc . the weight 60 facilitates the reciprocal movement of the inner cylinder 14 with respect to the main body 12 . the weight 60 forces cylinder 14 out of the main body 12 to further restrict inhalation and exhalation or with pulsing to force cylinder 14 back into the main body 12 . in accordance with the provisions of the patent statutes , the present invention has been described in what is considered to represent its preferred embodiment . however , it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope .
