HIGH PITCH WHISTLE FOR CALLING ANIMALS Filed Aug. 5, 1953 INVENTOR. HOWARD E. L/EBELT United States Patent HIGH PITCH WHISTLE FOR CALLING ANIMALS Howard E. Liebelt, Cincinnati, Ohio, assignor to Joseph B. Biederman, Cincinnati, Ohio Application August 5, 1953, Serial No. 372,505
1 Claim. (Cl. 46-179) This invention relates to a whistle having a high pitched note which may be heard by a dog or other animal, but which can not be heard by the human ear.
An object of this invention is to provide a so-called dog whistle having means for adjusting the pitch.
Another object of this invention is to provide a whistle which is substantially fiat in shape, and naturally fits the contours of the mouth.
A further object of this invention is to provide a whistle of this type, which can be easily disassembled for cleaning the component parts thereof.
Another object of this invention is to provide a whistle which may be manufactured and assembled quickly and inexpensively.
From the following detailed description and the drawing, the above and other objects and features of the invention will be apparent to those having ordinary skill in the art to which it pertains.
In the drawing:
Figure 1 is a plan view showing a whistle constructed in accordance with an embodiment of this invention;
Fig. 2 is a view in section taken on line IIll in Fig. 1;
Fig. 3 is a view in section taken along line IIIIII in Fig. 1;
Fig. 4 is a fragmentary view in bottom plan, looking in the direction of the arrows IV IV in Fig. 2; and
Fig. 5 is a perspective view of a pitch adjusting plunger of the whistle.
In the following detailed description, and the drawing, like reference characters indicate like parts.
As shown in the drawing, the whistle includes a hollow body member 10, generally of channel shape, having a Web 12 (Fig. 3) and flanges 13. One end of the channelshaped body member is closed by a wall 13a. As shown in Fig. 2, a portion or" the web 12 slopes upwardly to form an inclined face 14. A cover member 16 is mounted between the flanges of the body member at one end thereof, and over the inclined face 14. As shown in Fig. 3, the flanges 13 are provided with shoulders 17 on which the cover member rests. The cover member may be held in place on the shoulders 17 by means of a metal spring clip 18 which embraces the body member and the cover to hold the cover member in place on the flanges 13.
The cover member and the body member define an air channel having a portion 18 at the blowing end of the body member 10, of relatively large flow area and a restricted area portion 19 connected by a portion 21 which decreases in flow area from that of portion 18' to that of portion 19, because of the sloping face 14. As shown, the air entry end of the whistle is substantially flat so as naturally to fit the mouth. Indentations or grooves 21a and 211) are formed in the cover member and in the body member, respectively, by means of which the whistle can be gripped by the teeth.
The air channel discharges through narrow portion 19 2,737,757 Patented Mar. 13, 1956 against knife edge 22 of a thin metal member or plate 22. The plate.22 spans the flanges of the. body member, fit. An air chamber 22a is formed between the plate 22 and the web of the body member. The length of the air chamber 22a determines the pitch of the whistle.
and is held in place therebetween by the friction of a press The length of the air chamber 22a is controlled by a plunger 23, which is slidably mounted in the air chamber 22a. The plunger is provided with a knurled knob 24 which can be engaged by the thumb so that the plunger may be moved in and out of air chamber 22a, to alter the pitch. The plunger is provided with slots 26 forming wings 27 which engage the side of the flanges of the body member with a spring action to hold the plunger in position. Graduations 28 are provided on the plunger and on the body member for ease in determining the proper position of the plunger.
As shown in Figs. 2 and 4, a depression 29 is formed in the back of the web of the body member, opposite sloping face 14. This depression provides a place for a card or piece of paper 31, hearing indicia to identify the owner of the whistle or the dog which can be called by the whistle. The depression is covered by a cap 32 of transparent material which is frictionally held in the mouth of the depression and protects the indicia-bearing card 31.
As shown in Figs. 1 and 2, a small hole 33 may be formed in one end of the body member by means of which the whistle may be hung in any appropriate place.
When the whistle needs cleaning, the clip 18 is removed, to permit removal of the cover member 16. After the member 22 and the plunger 23 have been removed from the body 10, the parts of the whistle may be thoroughly cleaned.
The knife edge member may be held in proper forward position by lugs 34 formed integrally with the body member and which engage the edge 22.
The body 10, cover member 16 and plunger 23 can be molded from suitable plastic or resinous material.
it will be apparent to those of ordinary skill in the art to which this invention pertains, that various modifications may be made in the illustrated embodiment thereof without departing from either the spirit or scope of the invention.
Having described my invention, what I claim as new and desire to secure by Letters Patent is:
A high pitch dog whistle having an adjustable volume air chamber comprising a body of channel shape in section, the channel being open at one end, the air chamber being adjacent the other end of the channel member, a fiat cover for said channel member extending from the open end thereof to approximately the entrance to the air chamber, said channel having a wall sloping upwardly from the bottom of the channel member to a point spaced from the under side of said cover and a fiat wall parallel to the flat cover extending from said point to the inner end of said cover, thereby forming an air passage rectangular in shape and of small area in cross section, a fiat metal member covering a portion of said channel member adjacent the inner end of the cover and overlying the air chamber, said metal member having a knife edge at the end adjacent the inner end of the cover, said edge being substantially in a plane containing said fiat wall and being spaced a short distance from the inner end of said flat wall, and a plug disposed in the air chamber and under said metal member, the plug fitting the chamber closely and being adjustable along the chamber for adjusting the volume of the air chamber under said metal member and thereby the pitch of the whistle.
