The covers ha g nal age fior tions of the shells into silent contact with the cushioned surfaces of the padding. Therefore, across the body is a finger strap I8 which is suitable fabric covering 22, and fixed adjacent opposite sides of the body 20 on its convex side is a finger embracing strap 23.

The cushion i5 and its covering iii are provided near the upper end of the vibrator I!) with a groove 24 forming a constricted passage through which air trapped in the chamber 13 by the advance of units l0 and I9 toward one another will be compressed and forcibly expelled and projected in the form of air streams or jets.

Obviously, the device so far described may be utilized for the purpose of compressing air in the chamber and expelling it forcibly through the constricted passage formed by the groove 24, so that the air stream issuing from the passage may be suitably aimed and directed into the mouth of the user and by altering the size and shape of the oral cavity, sounds of varying pitch may be produced.

In order to render the device more effective I find it advantageous to provide a convexed diaphragm member 25 which is provided with a peripheral flange 26. The member 25 conforms in all respects to the size and shape of the cupped bodies H and 20 but is attached to the flange 2| of the member 20 in any suitable manner so that the flanges 2i and 26 lie contiguous with one another. A cushion designated generally 21 overlies the flange 26 and like the cushion l4 comprises a body 28 of sponge rubber or the like encased in a fiexible covering 29 of chamois skin or the like.

When the device employing the convex member 25 is used it will be obvious that the cushions l4 and 28 will be brought into contact with one another as the units are advanced toward one another, and will serve to restrict the distance that the convex member 25 may enter into the chamber I 3. At the same time the displacement of the air in the chamber l3 by the approach of the companion units will be materially increased so that the same volume of air expelled through the constricted passage 24 in the cushion M will likewise be increased without requiring the expenditure of any appreciable increased amount of energy.

In use, the two units It! and i9 are fastened on the left and right hands of the user by way of: the straps 23 and [8 so that the convexed outward surfaces of said units are thus strapped into the cupped hands. Obviously, by moving the hands toward and from each other according to requirements of a predetermined tempo and in keeping with the rhythmic pattern in mind, surrounding air is picked up, trapped, and compressed between the convexed diaphragm mem-. ber 25 and the surfaces defining the stated air chamber I3. The thus compressed air is expelled in jet-like streams, which latter are potential tone waves. Upon entering the oral cavsound or tone waves within the confines of the stated mouth. Then, and according to the skill of maneuverability of the month by the performer, he is able, using my hand pump, to make music in a novel fashion.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described my invention, what I claim as new is:

1. An air-trapping, compressing and air expelling" device for projecting and directing air streams into a users open mouth comprising, in

combination, a unit in the form of a hand-sized I concavo-convex body, said body having 2. marity of the open mouth of the user, as illustrated in a general way in Fig. 1, it will be evident that the air streams or waves are transformed into ginally arranged restricted air discharge orifice, and an air-trapping cover unit including a compressing and expelling member of such a size and shape that its marginal edge portions make air-tight contact with corresponding marginal edge portions of said bodywhen superposed upon the concave side thereof so as to cause said cover, unit to lid over and forcibly expel from the body through said orifice air trapped by the engagement of the two units.

2. The structure specified in claim 1, together with air tight cushioning means secured to and substantially surrounding the marginal edge por-. tion of said body.

3. The structure'speoified in claim said member is of convex form, the convex surface thereof being of size and configuration to telescope closely into the concaved side of said body.

4. An air-trapping, compressing and expelling hand pump for producing manually pressured airjets timed to conform to given rhythmic patterns comprising a concavo-convex adapted to fit with its convexed side into the cupped palm of one hand of the user, cushioned padding attached to and marginally surrounding. the concave side ofsaid shell and adjoined to the shell in substantially air-tight relationship, said padding being provided at a predeterminedpoint with a restricted air stream discharge ori--v fice, a second concavo-convex shell member adapted to be fitted into the cupped palm of the.

users other hand, said latter member constituting a cover for the open concaved side of thefirst-named member and being of a shape and size to permit its marginal edge portions to- REFERENCES CITED The following references file of this patent:
