WHISTLE.

Application filed October- 6, 1927. Serial No. 224344,

This invention relates to whistles and particularly to devices oi this class adapted to sheetmetal parts adapted when coupled together to term the whistle, and sald parts being providedv withv means f'OIJDlEGllOOk ing the same one with the other and to provide a substantially air-ti ht connection be tween said parts; a further object-beingjto provide a whistle, the separate parts ofwhich are so coupled together as to permit of the uncoupling of said parts at will for the purpose of cleaning, whereby the whistle may be maintained in perfect, operative condition at all times; a further object-beingto provide one ofthe parts of the whistle with extending, I in conjunction with the whi tle body, a finger ring or loop tor niounting the whistle upon the linger of awearer, -.the spring members iormingsaid loop adapting the whistle to lingers of dii'l'erent sizes; and with these and other objects in view,fthe invention consists in a device of the class and; for the purpose specified,which is simple in construction, eiiicient in use, and which is constructed as hereinafter describedand claimed. 7

The invention "is fully disclosed in, the following specification, of which the accompanying drawing. forms a part, in which the separate parts of my improvement are des-. ignated by suitable reference characters in each of the views, and in which-:

F g. 1 1S a longitudinal, sectional View through a whistle made accordingto my in-,

vention.

Fig. 2 1s a perspective view of one of the parts of the whistle device shown in Fig. ,1.

Fig. 3 is a perspective view of the other whistle part.

*ig. 1 is a section on the line 4 4 of Fig. 1; and, v g a Fig. 5 is a view similar to Fig. '1 but show ing a slight modification.

V In the construction shown in Figs. 1-to 4i inclusive, I employ two. whistle parts or

bodies

10 and 11, thepart 10 constituting the casingportion of the whistle and comprising a top wall 12, side walls13and anend wall 14:, forming at one end ofthe part 10, a box-shaped or eupshaped portion. The} top wall at the other end of the part 10 extends in a lip portion 15 which curves onto'the sides 13, the latter being cutaway as'showfn curved spring members forming other movable member Q S.

at 13. The top wall is also provided'with an aperture 16 which extends to a slightde onto both of t-heside walls 18, the aperture having a straight front wall 16 and an arc-shaped or curved rear wall 16 p in the construction shown, the side walls 13 are provided substantially centrally there oi with i lTwhich form, in conjunction with the body of the whistle, a linger ring or loop, in which a linger ofthe hand is adapted to be placed in mountiz the whistle on thehand. The inner faces oi the side walls 13, and the end wall 14 are provided with grooves 18, note Figs. 1 and t, which provide for the locking of the parts-11 in connection with the part 10, as later described. i

The. part 1-1 is also fashioned from sheet metal and comprises a bottom wall 19, side walls 20' and an end wall 21 forming asubj stantially box-shaped end portion which is adapted to lit within the box shaped portion of the part 10 in themanner showninFigs. 1 and L of the drawing. lhe bottomwall member and, is curved upwardly and out wardly in the form of a lip portion 22 which epcnding curved spring members so 7 19 is extendedat the open end the box isin alinement with the curvature and inclirf nation of the side walls set out at 135*. Thislip portion is bentb k u itself as seen at 23 at the outer end of'the 26; whichfi its within the side walls 20, and

the end wall 21 forming between it and the top and side walls of the part 10, a sound chamber 27 in which may be placed a ball or It will be noted thatthe member upward inclination forms; a contracted ,pas-

sage '29 adjacent the aperture 16 whereby the blast ofair'passed'into the chamberBO lead ingto said passage willbe directedonto the curved wall16 of the aperture 16 toproduce the proper whistle tone, part of the air entering the chamber 27 and agitating the ball 28 therein if such ball be employed. ltwill be understood that the height or inclination of the member, 2 L maybe variedto suit the I desired or required whistle t one or pitchu a The sidewallsQO and the end wall 21am providedwith outwardly projecting beads 31,

which are adapted to operate in the grooves chamberl27 except outwardly through thedischarge aperture 16, whereby the full blast of air may beutilized in producing the whistle sound or tone. I

i In Fig. 5 of the drawing, I have shown a slight modification wherein the extension of the bottom wall 19 from the member 24, insteado'f being in the form of a single arcsh'aped memberas the member 26, is fashioned into two arc-shaped-

members

32 and 33 forming within and between the whistle parts,

'

separate sound chambers

34 and 35 in which balls '36 and 37 may be placed, the chamber 3% registering with the aperture 16, whereas.

the chamber .35 registers with another aperture 38 similar to the aperture 16 but arranged rearwardly thereof. Intermediate the chambers 3 1 and 35 is formed a supplemental contraction chamber 39 by anupwardly inclined lip portion 40 to direct the air blown into the chamber 34 to the aperture 38 and the chain- 'ber '35.

Aside fromthe structure above described, the whistle tone in Fig. 5*will be the same as the whistle shown in Figs. 1 to 4: inclusive except that if it be desired, the body of I the whistle shown in Fig. 5' may be longer.

This type of a whistle, will produce a dual ortwo-tone sound as comparedwi'th the single tone or pitch sound of th'ewhist'le shown aswe'll as sanitary condition at all times; 1ft will-be understood that the 'part 11 is slid" into the part 10 by placing the beads'or prov jecti'ons 31 in the'grooves18fat the inouth- I this purpose.

1 to l inclusive. 7 In" both forms of construction shown,1the

separate parts

10 and 11 of the whistle, may

bestamped or pressed from sheet metal into the desired tornnand said parts coupled and uncoupled whenever desiredby virtue of the interlocking means employed. Inthis way, the chamber or chambers within the whistle may be kept clean, and the inner surfaces of thewh-istle cleaned at all times, to maintain the whistle ina-properly functioning pie'cejend of the whistle and sliding the parts one upon the other until the bead ofthe end wallf21 enters the'groove 18 in the end wall 14. In dissecting the parts, the 'nailof a finger may be-placed between the

end walls

21 and 14 ora'knife or similar tool used for 'In all types of whistledevices, it is cont mon'lyexperienced that the 'sound chamber thereof as well as the air admission chamber in the mouth piecebecomes-clogged with dust,

dirt and foreign matter, especially in carrying the same about in a pocket when the same is not in use, or 1n the use of the device, the

collection of moisture from the mouth, in the device, renders the'same not only inoperative but unsanitary, in e that the ability to thoroughly clean tliewhistle is rendered impossible by virtue of the unit structure thereof. With my improved whistle-device, however,'these objectionable features are obviated, and the whistle may be kept in a clean,

sanitary and operative condition at all times.

It will be understood that while I have shown a whistle of specific form and constructi'on, that my invention is not necessarily limited to the whistleherein shown and described, and various; changes therein and modifications thereof may be .made within the scope of the appended claims, without departing from thespirit of my invention, or sacrificing its advantages.
