Patented Nov. 17, 1942 il iE S'ii l2 Claims.

This invention relates to sound making devices and more particularly to such as utilize an induced air current in producing sonic vibrations in reed structures.

The main object of this invention is to utilize the inflation period of a single bellows for the enunciation of two distinct syllables, as pa-pa, and the deflation period for the enunciation of two distinct syllables as ma-ma, or vice versa, upon being reversed from one upright position to an opposite position.

Another object is to provide effective, completely inclosed, reed devices, productive of articulate sounds upon being reversed with respect to their ends.

A further feature is in the provision of means whereby the sounds are enunciated in distinct syllables, relatively long and short, at brief intermittencies, accented and modulated harmoniously.

A further purpose is to produce means by which the foregoing aims are fully attained by the relation of few and simple parts, well adapted for long continued service without failure.

These and other useful objects, further on apparent, are accomplished by the novel and practical design, construction and combination of parts, hereinafter described and illustrated in the accompanying drawings, constituting a concrete component of this disclosure, and in which:

Figure 15 is a similar sectional view of the device, in a reversed position from Figure 14, showing the bellows at the beginning of inflation and emitting a rst syllable.

Figure 16 is another like view showing 1the bellows almost completely iniiated, as emitting a second syllable.

Figure 1'7 is a sectional view, similar to Figure 14, the position of the casing being the same and the parts as reversed from that shown in Figures l5 and 16.

Figure 18 is another like sectional View showing the bellows nearly deilated.

Referring in detail to Figures 1 to 6 of the drawings, the numeral I5 generally designates a cylindrical casing, preferably made of strong paste-board, and of such dimensions as are compatible with its purpose.

Over one end is a disc I6, that may be of thin metal, having an annularly flanged rim I1, secured circumjacent the edge of the casing in the manner of a cap, and provided with a plurality of openings I8, except at its central portion I 9, which remains blank.

On the opposite end is a similar cap composed of a disc 23 having a flanged rim 2| and containing a single central vent perforation 22, provided with a exible iiat, flap valve 23 at its inner side, the valve being free, except at one point at its edge, where it is attached to the disc 20.

Disposed within the casing is a highly flexible bellows 25, its outer edge 26 being shown as turned re-entrantly over the edge of the casing I5, cemented thereto and further secured in fixed position by the rim 2l of the cap 2l).

The opposite, inner marginal edge 21 of the bellows material is secured by an adhesive to the exterior portion of a molded weight 30, of heavy material, such for instance as porcelain, flanged, as at 3|, in the manner of a cup.

This weight is of lesser diameter than the interior of the casing l5 to prevent the bellows fabric,

when deating, from damage by the wall of the casing and contains a central opening 32, having a counter-bore 33 in its flanged side.

Fixed rigidly in the counter-bore is a tube 34, to extend outwardly beyond the weight, to nearly contact the cap I6, causing the weight 30 to draw the bellows fabric straight, in order to inflate the bellows to its full capacity.

Telescopically engaged within the tube 34, and slidable through the weight opening 32, is a tubular guide 35 having one end 36 closed and secured to the cap element IS by any preferred means, as the rivets 31.

Set rmly within the guide 35, at a point near its open opposite end, in a manner to completely close the passage therethrough, is a circular block 38 having, in the side adjacent the closed end of the guide 35, a groove 39 in which is set one end of a longitudinal partition 4i), extending to make contact with the end wall 36 of the guide, thereby forming two equal air chambers, respectively 4I and 43.

Extending through the block 38 are two sound reeds 42 and 44, arranged in parallel and in relatively reversed relation, the reed 42 communicating with the chamber 4|, and the reversed reed 44 entering the chamber 43.

Formed in the opposite side walls of the tube 34 are passages 45 and 41, which are obviously moved whenever the weight 30 moves.

The guide 35 has ports 46 and 43, shown in Figures l and 3, registerable with the passages 45 and 41 respectively, upon movement of the weight 30.

Reversing the device from the position shown in Figures 1 and 2, to that of Figures 3 and 4, causes it to draw air into the space within the casing, via the openings I8, due to the descent of the weight 30, causing the bellows 25 to initially deiiate.

The air current, indicated by the arrows in Figures 3 and 4, is forced through the reed 44, into the chamber 43, which acts as a sound amplier.

The air current is created by the gravitational force of the weight 30, acting on the bellows 25, and causes the reed 44 to vibrate, emitting a sound, as ma, through the openings 41 and 48 until the openings become closed, by the sliding movement of the tube 34 relative to the guide 35, the tube 34 being fixed in the weight 30 which acts to operate the bellows.

When the passage 41 and port 48 are closed, a pause in audition is created, as the air in the bellows cannot escape through the valved vent 22, therefore being forced through the reed 42, which, being in a reversed position, acts as a non-vibrant mute valve for the escape of air only.

As the bellows slowly deflates, and consequently descends, the tube 34, fixed to the weight 3B, is moved to present its outer rim to the port 4B, opening it to allow the air, under pressure in the chamberV 43, to escape in a slightly compressed condition, causing the reed 44 to vibrate, emitting a second syllable, as ma Upon reversing the position of the casing, as shown in Figures and 6, a similar eect is attained in the production of two distinct syllables, as pa-pa; in this case the iniiation of the bellows is utilized, while its deflation produced the previously described eect.

As the weight 30, to which the bellows is secured, descends inflation of the bellows begins.

Air is drawn through the port 46 into the chamber 4I, passing through the reed 42 into the bellows, causing the reed to vibrate and emit a sound, as pan The weight continues downwardly, causing the bellows to further inflate, the port 46 is closed by the edge of the tube 34, causing a pause in audition; as the air current is prevented from entering the bellows 25 through the reed 44, the valve 23 raises, permitting air to enter the bellows.

Continuing, the weight 3B attached to the bellows descends, the tube 34 passing the port 4G and causes its passage to register, temporarily, with the port 45 in the guide 35, during which the air flows into the bellows through the reed 42. The slight vacuum created in the chamber 4| accelerates the vibration of the reed by reason of a more rapid flow of air, causing it to emit a second syllable, as pa.

Drawing air through the reed 42, causes it to vibrate and originate a short, distinct syllable, thence a quiet period, followed by a long continued syllable as the ports and passages arrive at the positions shown in Figure 1. i

Obviously the device may be constructed to originate more than two syllable sounds, depending on the position and number of ports and passages in the elements 34 and 35, and the sounds may be of widely different character, depending on the construction and tuning of the reeds.

In the embodiment, shown in Figures 7 to l2 inclusive, the casing 5U is identical with that previously described, consisting of a cylinder having a plurally perforate cap 5| at one end, and a plain cap 52 at its opposite end, in which is a single central perforation 53 provided with a flap valve 54.

The bellows 55 is secured at its outer end 56 to the cap 52, while its inner end 51 embraces and is cemented to a weight 6! freely slidable in the casing.

The weight has in its level under surface a depression 6|, while on its opposite surface is a raised hub 62 in which is a central transverse groove 63.

An inverted tubular cup 65 is firmly secured on the hub 62, the cup having an imperforate bottom 66 against which is fixed one of the end edges of a plate partition 61, its opposite edge fitting the groove 63, dividing the cup into two equal chambers 68 and 1U, in which are diametrically opposed ports 69 and 1|.

Circumjacent the cup 65 is a sleeve 15, having a flanged base 16 rigidly fixed to the cap 5I, the cup being telescopically slidable in the sleeve; this sleeve is provided with ports 11 and 19, which are registerable with the ports 69 and 1| during different stages of weight movement.

A raised annular rim on the weight is plurally recessed, as at 8|, to receive a corresponding number of arms 82 of a spider ring 83, the outer ends of the arms being flanged and fastened to the wall of the casing 50, thereby re-enforcing the sleeve 15 and maintaining it in fixed central position.

Set in the central portion of the weight, to extend into the depression 6|, is a sound reed 85, while another reed 86 is disposed in reversed position; thus the reed 85 communicates between the chamber 68 and interior of the bellows, while the reed 85 connects the air chamber 10 with the bellows.

As the method of operation is substantially the same as that of the foregoing device, it will be well understood by persons familiar with the art.

In the modification shown in Figures 13 to 18, a similar casing |00 is provided with an imperforzate cap IIII at one 'end and at the other end witha `cap :|02 having a plurality of perforations |03.

Attached to casing by theY cap IIII, is a bellows |05 secured at its opposite, inner end to the outer annularly ilanged wall |06 of a webbed weight |01, from the center of which, opposite the bellows, extends a cylinder |08 greatly reduced from the diameter of the wall |06 and having a chamber |09 open to the bellows.

Below the level bottom wall H0 of the chamber is a plunger head III, uniform in diameter with the cylinder and `having intermediate its length, .two opposed,v inreaching recesses H2 and H4, both being open at their outer sides.

The recess H2 Vis partially inclosed by a short down-reaching visor H6, while onthe opposite side a similar but relatively longer projection I II partially coversthe recess H4. The head III is thicker on the side H8 below the recess H2, than the opposite side H9, thus raising the bottom of the recess I I2, oisettedly from that of the recess H4.

Set in the wall I I0, and pointed in opposite directions, are a pair of. sound producing reeds and |2I respectively, the reed |20 extending from the chamber |09 to the recess H2, and the reed I2I from the chamber |09 to the recess II4.

Fixed axially in the cap |02 is a tubular member |24 Vto extend a distance within the casing and also outwardly therebeyond, to act as a guide for the head IH which is slidable therein.

When the device is in the position shown in Figure I5, the bellows is moved down by gravity, air entering the bellows through the perforations |03, recess H4, reed I2I and chamber |09.

Such movement causes the reed IZI to vibrate, producing sound, while the opposite reed |20 is mute; the sound continues until the recess cover III enters the tubular guide |24, whereupon a quiet period occurs until the head I I I passes outwardly beyond the end of the guide, thereby allowing air to enter the recess H4, direct, as indicated by the arrows in Figure 16, momentarily producing a second sound or syllable of diierent tonal quality.

It will be obvious that upon reversing the casing, as in Figures 17 and 18, similar but delayed effects are obtained by the reed |20, the delair being caused by the oiset relation of parts I I6 and H8 relative to the corresponding parts II'I and II9.
