Device for practicing breath control

Claim 2

In a device for practicing breath control, a container having top and bottom walls and extending therebetween a transparent upright wall through which the interior of the container is visible, a light-weight article in said container to be raised by upwardly flowing currents, said article being visible through the transparent wall of said container, and normally located adjacent said bottom wall means at said bottom wall preventing said article from directly engaging said bottom wall, and said transparent upright wall surrounding the article with clearance, inlet means accessible to the operator and communicating with the interior of said container, through said top wall, for enabling the operator to blow into the container currents which will flow downwardly into the container past said article therein and then beneath the article to raise said article in the container, discharge means providing communication between the interior and exterior of the container for dIscharging fluid out of the container, and adjustable resistance means coacting with said discharge means for adjusting the resistance to flow of fluid out of the interior of the container through said discharge means.

Claim 3

The combination of claim 1 and wherein said discharge means and adjustable resistance means are situated at and form a part of said top wall and respectively include a pair of plates one of which is formed with an opening and the other of which is formed with a series of openings of different sizes adapted to be selectively placed in registry with said opening of said one plate, at least one of said plates being movable with respect to the other for bringing an opening of a selected size into registry with said opening of said one plate.

Claim 4

In a device for practicing breath control, a container having a transparent wall through which the interior of the container is visible, a light-weight article in said container to be raised by upwardly flowing currents, said article being visible through the transparent wall of said container, inlet means accessible to the operator and communicating with the interior of said container, for enabling the operator to blow into the container currents which will raise said article in the container, discharge means providing a communication between the interior and exterior of the container for discharging fluid out of the container, and adjustable resistance means coacting with said discharge means for adjusting the resistance to flow of fluid out of the interior of the container through said discharge means, said discharge means and adjustable resistance means respectively including a pair of plates one of which is formed with an opening and the other of which is formed with a series of openings of different sizes adapted to be selectively placed in registry with said opening of said one plate, at least one of said plates being movable with respect to the other for bringing an opening of a selected size into registry with said opening of said one plate, said discharge means including an end wall of said container formed with a discharge opening, and said adjustable resistance means including a plate on said end wall formed with a plurality of openings of different sizes and selectively movable with respect to said end wall to situate a selected one of said openings of said plate in registry with said opening of said end wall.

Claim 5

In a device for practicing breath control, a container having a transparent wall through which the interior of the container is visible, a light-weight article in said container to be raised by upwardly flowing currents, said article being visible through the transparent wall of said container, inlet means accessible to the operator and communicating with the interior of said container, for enabling the operator to blow into the container currents which will raise said article in the container, discharge means providing a communication between the interior and exterior of the container for discharging fluid out of the container, and adjustable resistance means coacting with said discharge means for adjusting the resistance to flow of fluid out of the interior of the container through said discharge means, said discharge means and adjustable resistance means respectively including a pair of plates one of which is formed with an opening and the other of which is formed with a series of openings of different sizes adapted to be selectively placed in registry with said opening of said one plate, at least one of said plates being movable with respect to the other for bringing an opening of a selected size into registry with said opening of said one plate, said discharge means including an end wall of said container formed with a discharge opening, and said adjustable resistance means including a plate on said end wall formed with a plurality of openings of different sizes and selectively movable with respect to said end wall to situate a selected one of said openings of said plate in registry with said opening of said end wall.

Claim 6

The combination of claim 3 and wherein said end wall has a central axis, and said plate of said adjustable resistance means being turnable about said axis with said openings of different sizes respectively being situated along a circle at a radial distance from said axis equal to the radial distance of said opening of said end wall from said axis, and said discharge opening of said end wall being at least as great as the largest of said openings of said rotary plate.

Claim 7

The combination of claim 4 and wherein said end wall has a central tubular extension forming said inlet means, said plate of said adjustable resistance means being turnable about said tubular extension.

Claim 8

The combination of claim 5 and wherein said tubular extension carries an index for indicating when a selected opening of said plate is in registry with said discharge opening.

Claim 9

The combination of claim 6 and wherein said inlet means includes an elongated flexible tube carrying at its outer end a mouthpiece.

Claim 10

The combination of claim 7 and wherein said mouthpiece is removable to be exchanged for another mouthpiece of a different type.

Claim 11

The combination of claim 6 and wherein said end wall is a top wall of said container, said container having a transparent side wall and a bottom wall provided with an interior pin extending upwardly from said bottom wall into the interior of said container, said light-weight article being a ball which rests on said pin without engaging said bottom wall, so that fluid currents blown into the container can engage beneath the ball to raise the latter.
