ARTICULATIVE SGUiTD-PRGDUCING DEVECE FOR DOLLS, ETC- Application filed March 11, 1922. Serial No. 542,884.

This invention relates to soundV producing devices for toys, and more particularly to what are now commonly referred to in the art as talking dolls, said device being provided with means `for producing sound and effecting an articulated emission p thereof simulating the pronunciation of word syllablcs by the human voice.

t is the primary object and purpose of my invention to provide sucli a device wherein the several operative parts for producing and effecting an interrupted articulated emission of the sound are wholly contained and at all times operate within a chamber or casing of relatively limited dimensions so that it becomes possible to utilice such a device and mount the saine lwithin the bodies of small sized dolls for retail sale at comparatively low cost.

More particularly, my invention comprebends such a sound producing and articulating device of the gravity automatic type as distinguished from the manually operable construction having a spring sustained air expelling member.

In a practical embodiment of my present improvements, l provide within the outer casing an axially positioned iiied guide and a gravity movabie weight supported by and slidable along said guide together with the sound producing element and means whereby the sliding movement of the weight along the guide will produce an interrupted sounding of said sound producing element.

lith the above and other objects in view, the invention consists in the improved articulative sound producing de ,Tice and in the form, construction and relative arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently in corporated in the subjoined claims.

In the accompanying drawings,

Fig. 14:, is a transverse section takenl upon plane of line lit-14, Fig. 13.

In the embodiment of the` device which I have selected for purposes of illustration, l: provide a cylindricalV shell or casing 0 which may be produced of heavy cardboard, sheet metal orother suitable material. `At one of its ends, this casing is closed by a disc or cap c and at its other end by a similar disc or cap c2. These closure discs are preferably, though not necessarily, in the forni of sheet metal stampings, each provided at its outer edge with an angularly disposed `flange for frictional engagement with the respective ends of the casing or shell wall. It will be observed that this casing provides an unobstructed chamber', the axial or longitudinal dimension of which is substantially equal to its diameter. It is not, however, an essential requisite, of the invention that said casing or chamber shall be of cylindrical form as it will become obvious as this description proceeds that in so far as the effective operation of the device is concerned, said casing or chamber may be of various other shapes.

One wall of the casing above described is provided with one or more sound outlet or emission apertures. Preferably I `provide such apertures as indicated at 03 in the end cap or disc 0 of the casing. If desired, however, these apertures can be provided in the body w-all of the shell or cylindrical casing c.

lVithin the casing and extending axially or longitudinally of the chamber formed thereby there is arranged a fixed guide. As herein shown, this guide is in the form of a tuberi, which, as wil-l hereinafter appear, likewise functions as a sound receiving chamber. This fixed guide provides a support for the lfreely.slidablephe'ad b of the bellows which is generally indicated at B. Preferably, though not necessarily, the bellows head b is concentrically related tothe fixed guide tube i and' the'lwall of the casing c and is movableV along said tube from a position at one end of the casing chamber within which the bellows is enclosed to a position Substantially at *the opposite end thereof. i

lnI the present disclosure, I have shown a simple means for lxedly securing the guide tube ain place and to'this end, I provide the casing endv disc or capl @"centrally thereof with an inwardly projected portion ci which is adapted tobe' received within one end of the tubular post orguide. i rlahe other Tend ofthis tubular guide is provided at diametrieally opposite points with the lon gitudinally projecting lugsa for engagement in suitably formed re'cesifiesli"y provided in a paxrt 'of the other bellows head o2 which is suitably fixed to theV inner side of,vr the end disc or cap 0,2 of the casing. The, projecting lugs a" are of suchlength that betweentliese lugs and the bellows head b2,v the ports a* are procliicecljvliich afford communication betweenv the interior ofthe tubular post ci, and the yinterior of the bellows B through which the air may freely enterV into the bel,- lows or be expelled therefrom;

The

Weight S ie.y Prevdedlrvitli 'e Central Opening sY loosely receiving the fixed guide post a so that saidy weight mayfreely'slidewithout binding alongsaid post` in leither direction'. In one side thereof the weight S; is vJrovided withA1 a. sound` outlet opening-i s,t `e inner end olf` which isA adapted',V to register with the emission slot oropening a? inthe wall Off the fixed euidetube a the elidne mevement ef said weight yalong the tube.y -The two bellows heads b and b2 are connected at their marginal edges with the opposite ends of the flexible collapsible tubular wall b3. This flexible wall may be produced from rubberized cloth or other suitable material.

Within the fixedV tubular post a thek sound producing reed r is mounted or supported in any suitable manner adjacent to the ports ax, Y v

ln the operation of the device above de scribed, assuming that the parts are in the relative positions shown in Fig. 5 of the drawings', upon the reversal of the device, the weightS and bellows head b slide by gravity along the fixed post a from one end of the casing chamber tothe other. Initially in rthis `sliding movement and before the opening s" of the weight i's in registering relation withy the slot in the wall off the guide post, there is a slight emission of sound produced by reed r in 'the initial expulsion of the air through saidl reed, such sound waves passing through slot atlanti,l between the wall of the tube andthe wall ofthe open-` ing s in the weight and hence through the opening sj. This initial emission ofsound inV small volume simulates the sound ofthe letter M The sounding of the letter a immediately follows by the emission of sound from the. interior of the fixed tube a, in larger volume. throueh the slot (r2 and the opening s" of the weight which is` now in registerine relation with said slot. As the opening s y'moves outA of registering relationl with the slot a2' to aV position below the same,

the sound wavesvfrom the interior ofthe tube. againA pass in reduced volume between the wall of the tube and the weight S through the opening s,` again simulating the letter l\fl"an d when thewweight s moves entirely below the slotl a2, the sound again issues throughA said slot in maxiiriuni volume which continues until the. weightedl head of' the bellows reaches its final position of rest as s hown in llig. 4 of thejdrawings and during which time the sounding of the letter a is simulated. Inv this, manner,` the Sueeeeeve preliuneietienef the tvo Syllables 0f the infant ery me-me? elfe realistically simulated.

When the device is again inverted from, the position in Fig d, the bellows is ex,- ieended. by the` sliding 'meveinent of the Wei'a'ht S te the-r Opposite, enel 0f the casing Chamber and: air enterethe bell'ewe through the Slet e2 and; the pertes, ci* ofi the tubular peet. e

From the above description, itl will'V be Seen. that the Grenet/ire: parte of.' the derivee beth felt producing en@ ertieulating vthe sound are at all times wholly contained WithinA the ehembeli ef the exteenel" ieeetecting casingI andV by thet elimination' of protuberant or extraneous elemente,` it;

comes possible to utilize such devices in dolls or toys of comparatively small size.

In this connection, I herein use the term seit-contained as indicative et the tact that the enclosement of the operative parts is complete, there being no protuberant parts, and no extraneous manipulation other than that involved in changing the inclination of the device to effect the otherwise automatic action of the gravity-valve slide member S, as hereinbeitore set forth.

The device is not only simple and inexfive ot structure, but is also practically indestructible and tool-proof under ordinary conditions oli use, since it is not subjected extraneous pressure, and is essentially automatic in operation to all intents and purposes, i

Furthermore, it is to be noted that the only movable part in my device, relatively ng, other than the flexible sides ot the s, is the bellows head 7), and its innv attached slide-valve-Weight S, recally mounted on the rigid guide tub atter is also an important economic in structure in that it functions as air c ion chamber, reed container, and .l lateral support for the member S,
