SOUND-EMITTING DEVICE.

Application filed January This invention relates to improvements in sound emitting devices capable of pro ducing a crying sound upon being maneuvered to cause its internal elements to change their relative position.

One feature of the invention is in the provision of means which automatically modulates the sound produced, causing a difference in pitch between the earlier portion of sound and the final or main portion.

A further purpose is to produce a device that is essentially simple and cheap to construct, instantly responsive to positional changes and dependent wholly upon gravity in the performance of its functions,

These and other allied aims and objects are accomplished by the arrangement of parts in the structure hereinafter described and shown in the accompanying drawing, forming a material part ofthis disclosure, and in which Figure 1 is a top plan view of a sound emitting device, made in conformity with the invention.

Figure 2 is a longitudinal sectional view taken on line 2'2 of Fig. 1.

Figure 3 is a plan view of the device showing the cover portion removed and looking in a plane indicated by the line 33 of Fig. 2. i

As shown in the drawing, the mechanism is enclosed in a thin metal casing 10, an elongated rectangle in shape, having a depression 11 and, near its raised upper edges is .an outstanding bead 12.

Resting on the head 12, when in position on the casing, is a cover 13'having a raised rim 14, forming a depressed panel 15 containing a plurality of fancifully grouped perforations 16, larger openings 17 being symmetrically disposed.

Fixed in the depression 11 is a flat block 18 secured by a screw 19, this block forming the base member of a bellows, the upper or movable member 20 of which is secured by a hinge 2.1,, such as a flexible strip of leather attached to the adjacent ends of each mem ber. 7

The bellows further include a thin flexible element 22, such as leather or textile fabric rendered air resistant, this material being cemented to the edges of the members 18 and 20 so that no air can leak.

At the end of the upper element 20, opposite the hinge, is a weight 23 of such 24, 1925. Serial No. 4,419.

character asto normallyclose the bellows from an open position, as shown in the broken lines in Fig. 2, to the closed position shown in full lines therein. 7

At about the center of the upper member 20 is an opening 24, over which is a reed 25, fixed on a plate 25 its projecting ends being fixed to the top of the member by any preferred means. An inverted metallic cup 26 is disposed over the opening 24, covering the reed 25, but avoiding contact with the same, the edge of the cup being held by an adhesive on the upper surface of the member 20.

The cup 26, has a relatively large perforation 27 at its center and at one side a minute vent perforation 28 permitting a limited passage of air, these perforations constituting'major and minor openings.

Secured to the innersurface of the end wall of the cover13, adjacentthe hinge, is the flanged foot 29 of a resilient leaf 30, ex-

tending normally straight and parallel withwhen the bellows is expanded, as in the broken lines inFig. 2, covering the opening and preventing the passage of air during theearlier part of, the bellows movement when closing, air at that time passing through the perforation 28. I

In operation the device is raised and inverted from the position shown in Fig. 2, the weight 23 causing the bellows to expand, air being admitted to its interior through the openings 27 and 38, the former being closed during the latter part of the opening by the leaf element 30.

Upon reversing the device, into the position shown, air is forced out of the bellows by reason of the weight, the air passing to vibrate and produce sound of a certain intensity or tonality, the air escaping into the cover through the small perforation 28; later, when the larger opening 27 is released from the spring leaf, 30, the bellows closes more rapidly and the volume of sound is through the opening 24, causing the reed 25' i increased and changed, producing a difi'erent I note, the sounds eventually escaping into the atmosphere through the openings in the cover.

Thus it will be seen that the cover carried flexible leaf 30 operates automatically to modulate the sound-produced and also to accelerate the initial closing of the bellows.

Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the pressi'on, the movable element; of said bellows being hinged at one end and having a central opening and carrying a weight, a reed disposed in the opening, an inverted cup fixed on said movable element to cover said reed and opening, said cup having a major and minor perforation, and a flat resilient member carried by said cover at the end of said casing adjacent the bellows hinge adapted to close the major perforation therein when the hinged portion of the bellows is partially raised.

2. A sonnd'emitti'ng device comprising a rectangular casing having a centrally depressed port-ion, a perforate cover tight fitting the casing, a bellows fixed in the depressed portion of the casing, said bellows having a hinged element containing an opening. a weight on said hinged element, a vocal sound producer including a reed fixed on said element over the opening, a cup cnclosing the Vocal element and having a central relatively large opening and a small opening,

and means carriedby said cover to close the central opening at the initial stage of bellows closure.

3. A sound emitting device comprising an oblong rectangular casing, a cover reinovably engaged. on said casing, a stop on said casing to limit the cover, a bellows in the casing, said bellows being gravity operated upon reversion, a reed vibrated by air from the bellows, an inverted cup permanently secured on said bellows to cover the reed, said cuphavin'g' an air passage, and a spring leaf carried wholly by said cover to modify the transit of air through the passage during the initial exhalation of air from said bellows, said leaf being" in contact with the movable part of said bellows when open to cover the passage therein.

4. A sound emitting device comprising a casing having a cover, a bellows in the easing, there being an opening in the movable member thereof; a reed vibrated by air from the bellows disposed adj acently over the opening, a convex cover over the reed and opening, said convex cover having two perforations of unlike area; and a flat spring leaf having a part secured to said cover and another part adapted to restrict the passage of air from the'bell'ows through the larger of the mentioned openingswhen the bellows is fully expanded and during the earlier part of its closing movement, all of said elements being enclosed within the casing.
