| f IMWVMUWI INVENTOR. Josephus Thompson BY l Patented July 4, 1950 'U;I\1I'l`ll)v ,STATES PATENT OFFICE 6 Claims.
This .invention relates to musical instruments .or toys and particularly to such vdevices which, by `l-iumming into, may be made to imitate or reproduce sounds of other musical instruments.
The primary object of this invention is to prov-ide -a small, compact instrument of the kind stated, and which may -be easilymade and assembled out of relatively Vfew parts.
Another tobject is to provide such device with a baille plate which increases and renhances its senor-ity and resonance.
A further object is to `construct such Yinstrument with a removable diaphragm vso that the instrument body may be easily cleansed.
fStill another object is to provide .such in- -strument with a circuitous and restricted air passage.
These and other objects of the invention will become apparent from a reading of the following description and claims, together with the accompanying drawing, in which like par-ts are referred to and indicated 'by like reference characters and wherein:

Figure 11 is an insideor sectional view Vof the instrument, taken substantially along the line and in the direction of the arrows l I-il of the Figure 2; and
Figure 12 is a side viewof the bottom portion `of the instrument. with -parts broken away to show construction.
'Figures of a modified form Figure 13 is a top .plan view of a modied form of .the invention;
Figure 14 is a cross-sectional view of the instrument, taken along the line and in the direction of the arrows |4--I4 of the Figure 13;
Figure 15 is a front end view thereof;
Figure 16 is .a cross-sectional view thereof, taken along the line and in the direction Aof the arrows Iii- I6 of the Figure 13;
Figure 17 is aside view of the top portion of the instrument, with parts broken away to show construction Figure 18 is an inside or sectional view, taken substantially along the line and in the direction of the arrows |8-l8 of the Figure 14;
Figure 19 is an inside or sectional View, taken substantially along the line and in the direction of the arrows IQ-IS of the Figure 14; and
Figure 20 is a side View of the bottom portion of the instrument, with parts thereof broken away to show construction.
Preferred form The preferred form of the invention consists of a resonance box or chamber, broadly indicated by the reference character 3U, and which has .a removable vibratory member mounted thereon.
The bottom portion 32 of the chamber is a fiat, circular piece vof plastic material which has an inwardly turned brim portion therearound. It has two small spaced holes or egresses .38 eX- tending therethrough which are about threesixteenths of an inch in diameter. Small tubulai portions i2 extend inward from the flat inside wall .36 of the bottom portion, around the Aopening y38, as is clearly shown in the Figures l1 and 12.
The top portion 3| is shaped somewhat like the bottom portion 32 and has a similar inwardly turned iiange lwhich abuts the yaforesaid flange on the bottom portion 32. The two portions 3| and 32 are cemented or otherwise joined together `at the bead 33 to form an air-tight joint thereat.
One side `of the abutting flange portions is open to form the ingress or orifice 34. The body or joined portions 3l and 32 of the instrument are shaped to form a mouthpiece, somewhat as indicated by the reference character v35 at the said orice.
The inner' wall 31 which is parallel to the other inside wall 36 has a cup 4l therein which partially and loosely ts over the short tube 42,
somewhat as shown in the Figures 2 and 4. Air blown in the chamber 30 at the ingress or opening 34 can escape only through the egress 38. However, before passing through the egress 38, it has to pass along the outside of the short tube 42 and into the cup 4I. A free flow of air is restricted and as a result, a slight air pressure is maintained inside the chamber immediately in back of the' diaphragm 46.
The top portion 3l has a round hole 43 therethrough which is about one-half inch in diameter. The portion 3l is recessed around the hole 43, as is indicated by the reference character 48 in The vibrant member consistsof a diaphragm` and a removable cap. The diaphragm in turn consists of a small circular piece of thin membranous material 46 securely mounted on the fiber ring 41. The diaphragm is insertedin the recess 48 of the top portion 3l and so that the open membrane squarely fits over the hole 43. The cap 44 is round and has severalsmall vents or air holes 45 therein. It also has a flange 49 therearound whichtightly iits into the recess 48 over the edge of .the diaphragm, as shown in the Figure `2. The cap 44 is hollowed inside and permits the diaphragmto expand and vibrate therein.' ,It may be removed if desired to cleanse the instrument or to replace the thin diaphragm if necessary. -f
Modified Form The modified form of instrument closely resembles the preferred form in appearance. Outwardly it looks the same, except that the modified form does not-have the prominent removable cap 44thereon.
lThe bottom portion 62 ofthe instrument has an inwardly or upwardly turned flange therearound. It has two spaced vents or egress openings 68 and has supports 12 for retaining the diaphragm member 46 Vand 41. The supports 12 are simply small yblocks of plastic material, each of which has an inwardly facing shoulder 13. The, supports are arranged so that all the shoulders form a circular mount for the diaphragm member.
The top portion 6l of the modied form also has aninwardly or downwardly turned flange, the edge of which is cemented to the aforesaid upwardly turned flange. .One side of the joined portions .is open as at 64. and is similarly provided with a suitable mouthpiece 65. It has several small vents 15 therethrough which are over the diaphragm 46 mounted on the supports 12. The space inside the box or chamber 60 is partitioned off by a wall 69. This wall 69 extends between the two facing inside walls 68 and 67 and forms an arcuate passage 1I inside the box. The
partition has openings 16 through which air may y ment, for example, the mouthpiece 35 is placed to the lips and a tune or sound is hummed'into the chamber. The sound Waves set the diaphragm 46 in vibration. These vibrations are transmitted to the flat Wall 36 which acts asa from original oral sounds.
"also come withinV 4 l baflie and are then amplified and made resonant. Normal breath will pass through the instrument and out through the egress opening 38 as aforestated.
Modifications of tone may be obtained by either closing one of the egress openings 38 with a finger or by partially closing both openings simultaneously. By closing vand opening the egress Vents as g'just stated, the air pressure in the chamber is increased or decreased, as desired. The diaphragm 46 stretches or contracts in accordance with the pressure against its inner surface. `The vibrations thereof caused by the humming sound produced by the player are varied accordingly vso that a Wide range and wide variety of tones or sounds may be produced The modified form of the instrument is played in the same manner.
Having thus disclosed the preferred forms of the instrument, it is to be understood that the invention as described and illustrated is not to be regarded in aV limited sense, since there may be other forms-or modifications thereof which the scope of the appended claims. I f
