FIGURE 8 is an elevation, partially sectional, of a soft toy incorporating the device shown in FIGURE 5.
The sound producing device illustrated in FIGURES 1 to 3 comprises a tubular housing one part of which is an open-ended tube 5, moulded from a suitable plastic composition, that is, one being elastically expansible, which tapers slightly in diameter both internally and externally from one end to the other. At its wider end the tube is formed with an externally projecting annular flange 6, one face of which is conically bevelled, as shown.
Fitting within the tube is a generally cylindrical resilient plug 7, also moulded from a plastic composition, of such diameter that it can be inserted through the larger end of the tube and becomes wedged within the tapering bore of the latter on reaching a point about midway of the length of the tube. The plug includes a'cylindrical outer wall 8, a chordally directed wall 9 and a transverse wall it), closing the passage on one side of wall 9. The open ended passage through the plug on the other side of wall 9 receives and frictionally retains a pair of elongated sheet metal members 11, 12 constituting a reed assembly. Member 11 is pressed to give it the dished, boat-like shape shown and is of metal thick enough to render the member substantially rigid. Member 12 is a fiat strip covering the concave face of member 11 and is of thin elastically flexible metal. Conveniently members 11 and 12 are inserted in the plug 7 and the assembly is then inserted as a unit into the tube 5. At about the centre of its length member 12 is held frictionally clamped between member 11 and the wall 9 of plug 7 by virtue of the elasticity of the tube 5, which since of elastically expansible plastic will give slightly under pressure, but will seek to regain its undistorted form, thus causing a gripping, but the two end portions of member 12 constitute otherwise free tongues. The passage of air through the bore of housing 5 in either direction will cause one or other of these tongues to vibrate and produce a sound.
Fitted within the larger end of tube 5 is a closure member 13, formed of material similar to that of the tube. This closure member includes a tapered tubular stem 14, which is cemented into an enlarged end portion of the tube bore so that the two parts are securely assembled together to form a tubular housing. At the outer end of this closure member is an external annular flange 15 and a pair of spaced parallel bars 16 which extend transversely across the bore of the member. The bars i6 prevent 3,d75,3l7 Patented Jan. 29, lQfiS the withdrawal from the housing oi'the reed constituted by members 11 and 12, but do not appreciably interfere with the passage'oi air through the bore of the device.
The flanges 6 and 15 of'the tube and closure member define between'them an annular recess which can be used to assist the secure attachment of the sounding device to a toy. As shown in FIGURE 4, a hollow toy figure, formed of rubber or a flexible plastic composition, has itswall 17 shaped to provide an open ended, inwardly projecting sleeve 18 which will receive and frictionally retain the sounding device shown in FIGURES 1 to 3. On squeezing 'and releasing the toy, air is caused to flow outwardly and inwardly through the sounding device, producing a sound. To assist in the secure retention of the sounding device within the top, the inner surface of the sleeve'ls is formed with an annular rib 15; when the sounding device is forced into the'sleeves this rib is expanded by the conically bevelled face of flange 6 and then contracts to engage in the groove between flanges 6 and 15, as shown, rendering the sounding device virtually irremovable by a child.
The modified sound producing device illustrated in FIG- URES 5 anddcomprises an open'ended tube 20 and a closure member 21. The tube is moulded from a suitable plastic'compositio'n the same as that described above in connection with tube 5 of FIGURES 1-4 and includes a frusto-conical portion 22 and an inwardly directed annular flange 23. The tube includes a chordally directed wall 24 and a segmental transverse wall 25. The walls 24 and '25 are located approximately half way along the length of the tube and are formed integrally therewith. A reed assembly comprising members 11 and i2 is located within the tubewhere it is wedged betwcn the wall 24 and the inner cylindrical surface of the tubeso as to elastically grip members 11 and 12 by virtue of the elasticity of the outer open tube as already described with regard to FIG URES 1-4.
The closure member 21, which is made of a resilient plastic material, is generally tubular and comprises outwardly extending flanges 26, 27 and 28. The member is assembled with the tube Ztlby pushing it axially into the bore of the tube until the flange 23 snaps into the recess formed between flanges 27 and 28. The flanges 26 and 27 between them form an annular recess by means of which the device can be secured to a toy.
The closure member is provided with a fine mesh gauze 29, the function of which will presently be described, the gauze 'being'retained by means of intersecting bars 30 formed integrally with the closure member.
FIGURE 8 shows the device of FIGURES 5 and 6 incorporated into a soft toy. The toy comprises a shaped continuous outer covering 31 filled with a soft stufiing material 32. A hollow resiliently compressible ball 33 is embedded in the stuffing and spaced from the covering. The wall of the air ball is apertured to receive the sound producing device, which is secured in position by pushing it into the aperture so that the material surrounding the aperture is expanded by the conical portion 22 before snapping into the annular recess formed by flanges 26 and 27. By squeezing and releasing the toy, the ball 33 can be compressed and allowed to re-expand, thereby causing air to pass through the sounding device. The gauze 29 prevents the entry into the housing of the sounding device of pieces of the stufiing material which would tend to clog the reed assembly.
In the device illustrated in FIGURE 7, which is otherwise similar to that shown in FIGURE 5, a perforated diaphragm 34 is formed across the bore of the closure member, this diaphragm serving the functions of preventing both the withdrawal of the reed assembly through the closure member and the entry of stufling or other extraneous material into the tubular housing, thus rendering the provision of a gauge mesh unnecessary.
it will be appreciated that the various constructional features of the devices illustrated in FIGURES 5, 6 and 7 are applicable either singly or in combination to the device shown in FlGURES l, 2 and 3. Other modifications are also possible, for instance the bars 16 (FlGURE 2) and 3% (FEGURE 6) can be replaced in each case by a single centrally located bar serving the same functions.
