WHISTLE.

Application filed September 24, 1926. Serial No. 137,428.

1 provide a whistle of the class specified composed of a plurality of sheet metal. parts fashioned and secured together to form a sub stantially unitary body and a finger ring or loop on said body, the several parts of the whistle being so constructed as to permit of the manufacture and sale of the device at a nominal cost and yet produce a strong, durable whistle structure and one involving the desired tone and tone quality characteristics; a further object being to provide a whistle of the class specified with an adjustable finger ring or loop whereby the whistle body proper may be moved into different positions with relation to said ring or loop for convenient use upon the hand of the operator; a still further object being to provide a whistle having two or more whistle chambers or. bodies producing in a single unitary construction, whistles of two tone characteristics or qualities, as for example, the tone values of what is known as a police whistle and the tone values of a traffic or signal whistle whereby the single body is adapted for a double use or purpose; and with these and other objects in view, the invention consists in a whistle of the class and for the purpose specified, which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accomg panying drawing forms a part in which the separate parts of my improvement are deslgnated by suitable reference characteristics n each of the views and in which Fig. l is a longitudinal sectional View through one form of whistle made according to my invention. 7 V

whistle shown in Fig. 6; and

Fig. 5 is a view similar to Fig. l but showmg a modification. t

I Fig. 6 1s a plan view of a dual whistle body Fig. '7 is a longitudinal section of the Fig. 8 is a partial section on the line 8-8 of Fig. 7. y

In forming the whistle shown in Figs. .1 and 2 of the drawing, I employ two blanks 10 and 11, the blank 10 being shown in Fig. 3, and consists of an elongated body of sheet metal, one end 10 of which is provided with laterally directed members 10. Adjacent the end 10 is a part 10 foldable'on the line l0 and fashioned to form a curved lip portion of said part 10 in the resulting whistle.

part 1O is folda-ble on the line l0 and eX-. tends onto the part 10 and at right angles thereto as clearly seen in Fig. 1 of the drawing to form a stop wall to limit the forward movement of a ball or otherinember 12 disposed within the whistle body as seen in Fig. 1.

It will be understood that the part 10 con stit-utes the lower structure of the resulting whistle body and the projecting members 10 are curved downwardly and inwardly to form thereof an open finger loop or ring 13. The body 10 is also preferably curved upwardly to form on the lower face of the resulting whistle body, a convex recess extending longitudinallythereof to fit the contour of the finger of a hand. It will be understood, at this time, that the members 10" are movable toward and from each other andpossess a certain amount ofspring properties for adjustment of the whistle device to fingers of body is fashioned from the blank' llshown I in Fig. 4 of the drawing which is in the form of a rectangular body l1 having a projecting tongue 11 at one side thereof, and the body 11 is drawn in cup fashion to form therewith a chamber 14. Said chamber is closed by the body lO and thepartsfoldable thereon. The body 11 is provlded adjacent the projecting tongue l1 with anarc-shaped aperture 15 through which the sound passes,

wall ,said wall extending upwardly and inwardly to form at the inner end of the projecting tongue 11" a comparatively narrow discharge aperture 16 whereby a blast of air blownthrough the opening 17 in the lip portion of the whistle formed by the parts 10 and 11 is discharged into the chamber 14 of thewhistle body and moves the ball 12 in said body to cause aloud blast, this result being also accomplished in the passage oithe air over the beveled edge 18 formed around the aperture 15 in the body 11 of the whistle.

In Fig. 5 of the. drawing, I have shown a sligl'it modification in which I have sul stituted for the parts 10, 1Q andlO on the body 10 ofthe whistle, two parts19 and 20, the part 10 being foldable at right angles to the body 10 of the whistle to form a stop wall for the ball 12 similar to the wall 10*, and the part 20 extends from the discharge aperture 16 outwardly and downwardly to form in conjunction with the'part' 11", the mouthpiece of the whistle] Otherwise, the whistle shown in Fig.

5 is or the same structure as thatshown in] Figs. 1 and 2 of the drawing;

In Figs. 6, 7 and 8 or the drawing, I have shown another modification whereinl'provide an elongated whistle body 21, one end of which is fashioned to form a single whistle chamber 22 having a mouth piece portion'23, similar in construction to the mouthpiece portion shown in the whistle body illustrated in Fig. 1 of the drawing, the cham-' ber 22 containing a movable ball or other body 24. .Disposed at the opposite end of the: body 22 are two chambers 25 and 25 which open outwardly in one mouthpiece portion 26 and are subdivided by a central partition wall 27 which extends into the innor end portion of the chambers 2525 as seen in Fig. 7 of thedrawing. Inwardly of the mouthpiece 26 are two sound discharge apertures' 28 and 29 disposed at different pointswith relationto the end oi the mouthpiece 26 and opening intothe separate chambers 25 and 25 whereby a blast of air. entering the aperture inthe mouthpiece 26 and the separate chambers 25 and 25 will produce in a single opera tion, two dillerential. tone whistle sounds common in what is known as police whistles. IThe chambers 25 and 25? are separated from the chamber 22 by a partition wall 30 seen in Fig. 7 of'the drawing. It will be noted that the partition wall 30 is arc-shaped in form, the concave face being directed to the chamber 22 whereby in the operation of the soldered or otherwise secured together as is also true in securing the parts of the whistles shown in Figs. 1 to 5 inclusive.

in Figs. ,6, 7 and 8, I have also shown a finger ring'or loop 32 which is pivoted substantially centrally of the whistle body 21 or, the lower face thereof, the ring or loop 23 being of the split type totorm independently adjustable members 32 to adapt the same for use on fingers of different sizes. This ring or loop is pivotally mounted in connection with the body 22 as seen at whereby the same may be adjusted into dillerent angular relations with reference to said body todispose the mouthpieces 23 and 26 in desired relation with reference to the hand, to'tacilitate the use of the whistle.

it will be understood that an adjustable linger ring orloop may be incorporated with a single whistle body as well as with the double whistle body as seen in Figs. 6,

'Z and 8 of the drawing, and also a solid or otherwise constructed linger .loop' may be employedin connection withthe dual whistle body,-and various other changes in and modifications Y of the construction herein members, said ring or loop being pivota'lly' supported in connection with the whistle bodyfwhe'reby said body is adjustable thereon} V 2. A whistle of the class described com prising a hollow body, a mouthpiece portion atone end o1 said body and openingthereinto,and a mounting ring or loop comprising relatively adjustable arc-shaped members, said ring or loop being pivotally supported in connection with the whistle body whereby said body is adjustable thereon, anothermouthpiece at the other end of said body, and means for dividing said body into independent sound chambers.
