Application filed. October 29, 1919.

To all whom it may concern:

lie known that I, Bnn'rniino Dn'BnnNrz, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Respirationlndicators, of which the following is a specification.

lhe present invention relates to improvements in respiration indicators, that is to 7 say to an apparatus designed to show proper or possible faulty ins )iration and expiration of air into andfrom the lungs, thereby aid: ing in correcting; the act of breathing.

it is essential that, in respiration, each time a long breath of air be drawn, so that both lungsbe fully filled with air. Each time a person draws breath, among other things, the diaphragm contracts, allowing; the lungs plenty'of room to expand. During ixpi'ation the diaphragm relaxes and rises in the form of a dome. Outwardly, this contracting and relaxing of the diaphragm is recognizable by the expansion and contraction, respectively, of the abdomen. ff durinn inspiration the abdomen does not expand and during expiration the abdomen does not :ontract, the respiration is faulty.

The main object of the present invention is to provide a simple and eflicient apparatus for indicating and measuring; tire expansion and contraction of the abdomen during inspiration and expiration, respectively.

Another object of the invention is to provide an apparatus of this type, which is adapted to be attached to the body of the person whose respiration is to be tested, thereby enabling the person to read the scale of the apparatus not only in standing" or sittingpositions, but also in lying position.

A further object of the invention is to so construct the apparatus that it may be conveniently adjusted to persons of different sizes.

A still further object of the invention is to produce a device of the character described which is capable of manufacture on a coin- Inereial scale. or in other words one which is not so difficult to make to be beyond. the reasonable cost of such a contrivance.

With these and other objects in. view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended Specification or" LettersE'atent.

Serial No. 334,357.

4 claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the ap pended claims without departing from the spirit or sacrificing any of the advantages I of the invention.

Une of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of an apparatus constructed in accordance with the present invention; Fig. 2 is a horizontal section taken therethrough, on a larger scale, showing the upper half turned over and reversed end. to end; Fig. is a front elevation of the device also on a larger scale; Fig. t is a section taken on line 47 of Fig. 1, on a larger scale; and Fig. 5 is an end view of the apparatus. looking in the direction of the arrow shown in Fig. l of the drawings.

In the drawings, the numeral 10 indicates an arc-shaped body, preferably made of metal and of any suitable cross-section. In I the case illustrated in the drawings, this body is made in the form of an angle iron, having a verticalfiange l1, properly curved or shaped to fit the abdomen of a person.

:UTGID this vertical flange extends forward a horizontal. flange 12, on which is provided a graduated scale 13, arranged on the are of a circle. The zero 'polnt of this scale is disoosed ad'acentthe left-hand side of the apparatus l), whilethe highest graduation mark is located adjacent the rigbbhand side of the body 10. The ends f the body 10 are closed byvertical plate members it and 15, which are preferably made integral with the body 10. Below-the horizontal flange 19., the body 10 is provided with an enlargement 16, extending through out its length. Through this enlargement extends a channel 17, which may be of any suitable cross-section, for instance circular. The channel is arc-shaped, its curvature corresponding to that of the flange 11, as clearly appears from 2 of the drawings. In the front portion of the enlargement 16 is pro vided a slot 18, extending substantially from tee plate member i l to the plate member 15, and from the front face of the said enlargement to the channel 17. With the scale 13 cooperates a pointer or hand 19, the same being disposed above the horizontal flange of the body 10 and made preferably integral.

. extensible wire rope 22, inclosed by a tube This tube is-tormed of coiled wire, the

coils of the said wire being arranged close to each other. One end of thewirerope,

' denoted by the numeral 24, extends into the channel 17 and has attached to it the handcarrying bracket 20. The other end of the said wire rope has drawn over it a cap 25 and is adapted to be fixed to the plate member l5. The tube 23 extends around belt 21 its full length from the said cap to the plate member 1st, one end or the said tube being attached to the said cap-and the other end to the plate member let.

In the plate member 15 is formed an opening 26, comprising a larger portion 27 and a smaller portion, 28; T rough the larger drawn, according to the requirements, and then shifted into the smaller portion 28 of the opening, whereby the capped end of the belt is held against longitudinal movement. It is obvious that any other suitable means may be provided for attaching the capped end of the belt to the-body 10.

The operation of the device is as follows: The arc-shaped body 10 is placed against the abdomen of the person whose respiration is to be tested, and the belt 21 carried around the body of the person, the capped end of the said belt being drawn through the opening 26 and clamped in the smaller portion '28 of the said opening exactlyat the end or" a respiration. In these positions of the elementsof the respiration indicator, the hand 19 is atzero on the dial. It the respiration of the person is correct, during the next respiration the abdomen expands, thereby shifting 'theend 2a of the wire rope 22 in the channel 17 in the direction of the'arrow shown in Fig. 2, carrying with it the hand 19; lVhen the abdomen is fully expanded, the said hand will indicate on the scale the extent of the inspiration. During. expiration, the coiled wire 23 causes the wire rope to move in the opposite direction, bringing the handl9 back to zero position. If the portion 27 the capped end of the belt is respiration is faulty, that is to say if the abdomen contracts during the inspiration, the wire rope is not shifted, or in other words the hand stays at zero. The person, watching 'thejmovement of the hand, thus becomes aware of the fact that the respiration is faulty and exercises until the desired result is obtained.

Obviously, the movement of the hand on the dial indicates not only proper or faulty respiration, but indirectly also the quantity oi air drawn in during each inspiration.

' lt'is obvious that, inasmuch as the respiration indicator is attached to the body of the person whose respiration is to be tested, the device may be used in standing, sitting and lying positions. The device may be easily adjusted to persons of diderent sizes, as appears from the foregoing.

it is also obvious that, while herein a spe ci'lic belt construction has been described, any other belt may be used without departing from the invention, which lies mainly in the provision of a rigid body provided with a graduated scale, in combination'with a belt, one end of which is fixed to said rigid body and the other end isshiftable thereon, said slnitable end carrying a hand or pointer coiiperating with said graduated scale.

What I claim is V 1. A respiration indicator comprising .a rigid body, a non-expansible belt having one of its ends shiltably disposed upon said body and its other end fixed thereto, said body having thereon a graduated scale, a hand cooperating with said scale attached to the shiitable end of said belt, and a spring acting upon said belt having a tendency to "keep said hand on zero position on said scale. V V

2. A respiration indicator comprising a rigid body, a wire rope having one of its ends shittably disposed upon said body and its other end fixed thereto, said body having thereon a graduated scale, a hand cooperat- 'ing with said scale attached to the shittable end or": said wire rope, and a spring tube inclosing part of said wire rope and having a tendency to keep said'hand on zero position on said scale.

3. In a resplration ind cator according to claim 2, said sprin tube being secured to the fixed end of said wire rope and to the opposite end of said body. 1
