WHISTLE Filed Aug. 25, 1935 Patented Sept. l, 1936 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to improvements in Whistles, adapted to give two or more tones of diierent pitch, and one of the objects of the invention is to provide an improved device of this character adapted to produce tunes of various kinds by the skillful manipulation of the parts of the whistle, one with respect to the other.

A further object is to provide an improved, simple and efficient device of this character, which will be compact in construction and effective and eiiicient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying draw ing illustrating this invention, and in which Figure lf is a side elevation of a whistle of this character constructed in accordance with the principles of this invention.

Figure 2 is a left hand end elevation of Figure 1.

Figure 3 is a detailed sectional view taken on line 3&3, Figure 1.

Figure 4 is a vertical, longitudinal, sectional view of Figure l.

Referring more particularly to the drawing, the numeral ID designates the body portion of the whistle which is preferably cylindrical in cross section, and may be formed of any suitable material, preferably wood.

The body is preferably solid and is of a length substantially greater than the cross sectional diameter, and is provided in one end thereof with a plurality of cavities or recesses II, opening through the end, and these cavities are arranged to encompass the longitudinal axis of the body portion and are of different depths.

Each of the cavities is of a substantial length and the outer periphery of the end of the body through which the cavities extend, is preferably tapered or beveled as at I2, the end terminating in a flat surface I3 of substantial diameter, and the beveled or tapered portion of the end of the body intersects each of the cavities at the ends of the latter to produce a sharp edge for the air which is blown against such edge, and also to provide an opening for the escape of the air which is blown into the respective cavities, to produce a clear but musical sound of different pitch, which varies according to the depth of the cavities in register with the mouth piece.

The numeral I4 designates a mouth piece which is tubular and is connected to a rotatable disc like member l5. The end of the mouth piece extends through the member I5r and is arranged to one side of the axis of the member I5. 5

The member I5 is preferably comparatively thin and is of a diameter substantially larger than the at end of the body IU and rests thereagainst, but is preferably of substantially the same diameter as the remaining portion of the l0 body I 0.

The member I5 is rotatably connected to the body in any suitable manner, preferably by means of a pin or fastening device I6 which passes through the member I5 and into the body I0, 15 so that the body I0 and the member I5 will be freely rotatable one with respect to the other.

The mouth piece I4 is so arranged that by a relative rotation of the body I0 and the member I5, one with relation to the other, the cavities 20A will be successively brought into and out of register with the open end of the mouth piece I4, so that air forced through the mouth piece I4 will enter the respective cavities I I striking the edges of the cavity and will then escape through the 25 opening formed by the beveled or tapered end of the body I0, which openings are shown at Il.

Within the mouth piece I4 is arranged a plug I8 having a beveled or tapered side I9, and the plug is of such a diameter that an opening 20 30 will be provided for the escape of air into the respective cavities that may be in register with the mouth piece I4.

The tapered or beveled portion of the plug I8 guides .and directs the air currents so as to cause 35 them to strike the sharp edge of the cavities that are formed by the beveled or tapered portion I2 of the body I0, resulting in a musical sound resembling that of a pipe organ, as distinguished from the sharp, shrill sound of a whistle. 40

The mouth piece I 4 is of any desired length and of a cross sectional diameter preferably substantially equal to the cross sectional diameter of the cavities I I, and the body I0 is preferably provided with an operating handle ZI, formed in any suit- 45 able manner, but preferably by shaping a portion of the body to form the same. If desired, however, the handle may be formed separately and then attached to the body.

In use, the mouth piece I4 is gripped between 50 the teeth or held between the lips and the breath is blown through the mouth piece, causing the air currents to be discharged against the edges of the cavities II.

Any air entering the cavities will escape through 55 the openings l1. At the same time the body I 0 is rotated by the handle 2i about an axis formed by the pin or fastening device i6, with the result that the cavities Il will be successively brought into register with the mouth piece lli, the body I0 being rotated in either one direction or oscillated about the pivot formed by the fastening device I6. Y

This will give different tone pitches in the musical scale of one or more octaves, according to the number of and depths of the cavities.

Furthermore, this device may be employed as Y a health instrument, by reason of the deep breaththe tune produced will be similar to thatproduced by a pipe organ.

been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new isz- 1. A device of the character described embodying Va body portion provided with a plurality of cavities of different depths opening through one end thereof, a tubular mouth piece, and means connecting the mouth piece to that end of the body through which said cavities open, whereby said body may be rotated with respect to the Vmouth piece to cause the said cavities to be successively brought into register with the mouth piece when the latter is held in the mouthand against rotation with the said body, the outer periphery ofthe end of the body in proximity to the said mouth piece being beveled to intersect said cavities to form sharp edges to be contacted by air currents discharged through the mouth piece.

2.
