SOUNDTPRODUCING DEVICE.

Application lediDecember 17, 1924.' Serial No. 756,434.

This invention relates to sound producing the construction of which, however, does not devices,`and more particularly to that type o'i'isound producing devices or voices of more or less recent development in the art, wherein there is provided within a suitable casing or housing aisound receiving chamber and a gravity movable air*expelling` member or'head, provided with means for automatically controlling the emission of the Sound produced by the expulsion of air from said chamber Athrough a reed, 'for the purpose of articulating the sound and simulat-v ing the characteristic cry of the doll or otherA toy, suchl as the word ma ma?.

The primary objectl and'purpose of my present improvements isto provide a sound emission cont-rol" means i for such voices thereafter during the remaining-portion ofV the movement of said member, the word"pa pal is sounded. I further propose to pro-y vide a sound `controlling meanswhich is so constructed that by resorting toy very` minor changes in the parts thereof, various combi-` nations ofthe word syllables ma and pa may be simulated.

InV one practical embodiment of theinven- I tion, I provide a tubular soundemission chamber having an orifice in its wall,t and la part on the gravity movable air expellingv member slidably engaged with said chamber wall and having means cooperating with the orifice therein to control the emission ofthe sound and el'l'ect the simulation of one word. In conjunction with this control part7 a second soundiemission controlling element is slidably engaged upon the wall of said sound' chamber andconnected to the air expelling element by means operating to `delay or retard the Amovementof'said element during the h'rst'partol the air expelling movement of'sai-d member, and thereafter cause the tion to provide an improve-d sound produc,

ing device or Voice of the above character,

greatly vary from suoli' devices now in practical use and in which the additional elements employed are of exceedingly sim-ple form and construction so that the production and sellingcostofthenew device is'maintained at a comparatively low ligure. y Withy the labove and other objects in view, the invention consists in the improved sound producing device, and in the form,construc tion and arrangement of its several pai'ts as will be hereinafter more fully described, illustrated i in the accompanying drawings and subsequently incorporated in the subjoined claims. In the drawing wherein I have illustrated one simple and satisfactory embodiment-of the invention and in which similar reference characters designate corresponding parts throughout the several views,- Y

Figure l is a vertical sectional iview illus` trati'ng the relativeposition of the several" parts of the device at the end of the movement of the air expelling member in one di rection,

Figure 2 is a similar view showingthe relative positions of the parts when saidf member hasl reached the end of its movement in .the-opposite direction,

Figure 3' is a horizontal sectional'view taken on the line 3-3 ofFigure 2,

Figuret is a similar section taken on the line 4-4 ofiFigure Q', and Y Figure 5 yis an end elevation.

For purposes of illustration in the accompanying drawings7 I have shownA a familiar type of.voice` or sound producingdevice whereinthe several operative parts are enclosed within a housing orcasing having a body wall of cardboard or other suitable material and preferably of cylindrical form, the opposite ends of this casing beingprovided 'with suitable end plates or caps 6 and projects from the outer side ot the member 9 in concentric relation with said opening. Through this sleeve and the air Chamber `termed by the collapsible bellows wall 8, a tubular post 11 extends. At its opposite ends, this post may be Centrally fixed or held in connection with the easing ends 6 and 7 in any approved manner.

The wall of the tube 11 at one of its ends is provided with an aperture 12 aiioi'ding communication between t-he bellows chamber and the interior ot sai d tube and within this end of the tube, the sound producing reed 13 is suitably mounted.

At a` point in spaced relation to the other end oi the tube 11, the opposed eireun'i'terentially extending` slots or openings 14- are provided in the wall thereof through which the sound is emitted Ytrom the interior of said.

tube into a sound receiving chamber of eon stant definite dimensions formed within one end ot' the easingr by a sound amplifying wall rlfhis sound amplifying; wall, as herein shown, constitutes no essential part of my present improvements, and, it desired, may be eliminated.

The sound emission control sleeve 9- on the weighty member 9 is provided intermediate of its ends with diametrieally opposed openings 16 in the wall thereof of substantially the same circumferential extent as the slots 14 in the wall of the tube 11. r1`he wall of the sleeve 9 is further provided interi-orly thereof with longitudinally aligned grooves or channels 17 and 18 respectively communicating' with one of the openings 1G at opposite sides thereof'. rlhese grooves are also in line with one oi the slots 14- in the wall ot the tube 11 and it will be noted that the groove 17 in the inner part ot the sleeve is ot greater length than the groove V18.

ln addition to the setuid control sleeve 9', a seeond sound emission controlling elen'ient 19 structurally separate troni said sleeve is loosely engaged upon the tubular post l1 tor free sliding' movement. This elen'ient 19 is relatively short and is likewise provided intermediate of its ends and at diametrieally opposite points with the oiienings 20 whieh are in longitudinal alignment with the openings lo' in the wall ot the sleeve 9.

The expansion coiled spring Q4 surrounds the sleeve 9 and the element 19 has one ot its ends suitably lixed as at 2.1 to tht` weighty head or member 9 and the other end thereof is suitably secured, as at 22, to the element i9.

The wall ot' the end cap or plate 7 on the Casingprovided with the usual sound emission openings Q3 therein.

1n the operation oit the device above described, when said deviee arranged in the position shown in Figure 1 of the drawings, the end of the sleeve 9 is engaged aOainst one end o1c the element 19, which is held under the weight of the member 9 against the metal cap or cover 7 on the easing. ln this position, the bellows Chamber is tally inflated with air and it will be observed that one of the slots 1li in the wall oi the tubular post 11 registers with the inner' end oi the slot 17 in the wall of the sleeve 9.

llVhen the device is inverted Ytrom the position. shown in Figure 1, the weighty head or member 9 in'imediately starts to move downwardly by gravity on the tube 11 and expel the air from the bellows chamber through oriiiee 12 and the sound prodneinr;` reed 1S. In the initial movement oi the member 9, the sleeve 9 thereof moves away from the element 19 which is held relatively stationary under the expansive pressure ot the spring 24, while the sound escapes trom the interior of the tube in relatively small volume through the opening` 14; in the tube wall, slot 17 and one of the openings 1G in the sleeve 9 and simulates the sound ot the letter in. In the continued movement ol the weighty member 9. the openings 1G will register with the slots 14 so as to permit the sound to be emitted in greater volume and simulate the letter a, thereby eoi'nplet-inp,- the first sound of the syllable ma.

At this time, the springr 2.4i is fully eX- panded so that through the connection ot said spring, with the element 19 and the member 9, said element 19 is Caused to more with the sleeve 9 along the tubular post 11, so that said sleeve and element are in the relative positions in said post substantially as seen in Figure 2 of the drawings. lVhen the end portion ot the sleeve 9 moves over the slots 14 in the tube wall. the volnme ot sound emitted is airain restricted. sut-.h restricted volume emitted throunh the groove 18 again simulatimil thi` sound ol' the letter m, and thereafter during the interval ol' n'iovement equivalent to the dist ance bel wenn the sleeve and the element i9. thi` irrealer volunle ot sound simulating' the letter a" is. again emitted, thus comidelingI the smindiiur oll the two syllable word ma ma. 1n the continued movement ot' the member 9, the lower end ol the element 19 movesy over the openings 14 in the lube wall and al'n'uptly cuts oill the emission oi' sound.

As this element 19 is not provided with the grooves or rliannelsI in its inner surface, it will be understood that the sound is com pletely eut oli". When. the openings 20. however, first register with the open ing; l-l. there is an abrupt release oli the sound and its emission, under f misifilerable pressure in the larger volume through tbe openings tl, thereby soundingl the letter a which rontinues until the other end portion ot tln` element 19 again completely Closes the openings 14, cutting oit the emission of sound for a short period in the travel of saitl sleeve and then again permitting et the emission lll) of sound in; maximum @volume through., said openingswhenfthe element 19. moves entirelyY below theopenings in. the final,y portion of the air .expelling movement of themembenl).l Thus, the-phonetic articulation of the Word pa pa?? issimulatedand follows .in closesuccession upon the sounding. ofthe word ma mal. By the provienen ot the separate sound control f clement 19 and i the spring connectionof said elenient-with the member 9,7I secure the desired time interval betweenrangementiinsures the complete inflation olf` the bellows chamberwvhen the device is inverted from the position shown 1n Figure 2,

so. as to. expand tliefflexiblebellows wal-l 8..

.From the.. foregoing description, considered 1n connection with the accompanying drawing, the` construction and manner oi"` operation. of 'my Present improvements will be clearly understood.` Itwill be apparent fromwhat has vbeen said, that-by the provision orthe omission of the Vopenings .16v and/or 201 and ofthe the longitudinal grooves 17 and/or IS-in oneior the other,

or both, of the sound control parts `9 and 19, any one..ofia` number of different combinations of the `Word syllables ma and pa can .be realistically sounded or simulated. Thus, for instance, by resortingl to such obvious mechanical changes, it is possible to. cause .the device -to simulate thephonetic articulation of the Wordsy ma ma, pa pa?, pav pa, ma ma,; ma ma, mama.; pa pa, pa pa; pa-pa, ma; pa,i ma ma?; pa pai; ma ma, pa; ma, pa and pa, ma.

However, it is thought that the arrangement which Will preferably be adopted in mostcases, is that illustrated fin the drawings, whereby `the. two multi-syllable word-s ma ma and.4 pa pai are successively sounded in a singleioperation of the device.

Thilo I haveherein shown an embodiment of the invention, which, in actual test, I have found to be highly satisfactory, it is nevertheless to be understood that more or` less satisfactory results might be obtained by various alternative arrangements ol the several cooperating elements and I accordingly reserve the privilege of resorting `to all such legitimate changes inthe form .and construction of the several parts as may be fairly embodied within the spirit and scope of the invention as claimed.
