United States Patent Office 2,697,298 Patented Dec. 21, 1954 BIRD CALL WHISTLE John H. Bacon, Wellesley, Mass. Application August 20, 1948, Serial No. 45,317 26 Claims. (Cl. 46-44) The present invention relates to a whistle and especially to one having a resonating pipe which may be varied in frequency and to means for producing a note which may be modulated at a low frequency beat, the frequency of which may be made to vary.

The whistle of the present musical instrument, a toy, or to imitate various nature calls of birds and other creatures. The whistle of the present invention is operated by an air jet, supplied by a person or in large embodiments by mechanical means. The air stream is directed against the mouth of the whistle at such an angle that a sound vibration results whose frequency is predetermined by the length of the resonant air column in the pipe of the whistle. To this extent the frequency is established in the same manner as in an organ pipe. In addition to this however a deflecting plate supported by means of a freely vibrating spring has its end positioned in the mouth of the whistle in such a manner and at such an angle as to cause a periodic interruption of the air jet against the lip of the mouth to produce the desired beat note effect or what may perhaps be more commonly called a modulation or warbling of the note of the whistle.

In the present invention the warbling or modulation does not affect the whistle note itself. Provision however is made in the present invention both for changing the frequency of the note and also varying frequency of the warble or modulation. The warble may also be periodically omitted. As a result of these provisions which form a part of the present invention, the whistle may be used to simulate a great variety of bird calls and is, therefore, of considerable interest to those who study birds and desire a simple device for imitating their calls. The whistle of the present invention will produce musical sound effects which are sometimes lacking in orchestral renditions because of lack of instruments able to produce the desired eifects.

In addition to these uses the present invention will furnish a compact low frequency standard of a standard note and also of a beat note by proper calibration respectively of the air column in the pipe or tube of the device and the calibration of the vibrating spring.

As a toy the device may have an animated figurine of a bird whose beak and eyes may move with the operation of the whistle. The device, whether toy or not, may be .made of any suitable material such as a metal or plastic and it may be cast or molded assembled together.

Without further describing the merits and advantages of the present invention, the invention will be described in various modifications as illustrated in the drawings, in which:

In the arrangement shown in Figure 1, the device comprises a mouth piece 1, a pipe 2 and a slidable plunger or piston. The mouth piece may be made of any suitable material such as metal or plastic and can be readily made by injection molding of a suitable plastic molding material such as cellulose acetate or other common molding powder used for that purpose. The mouth piece is provided with an air passage 4 which has a decreasing tapering passage directing a sharp narrow air stream at the lip 5 of the mouth 6. The direction of the air passage 4 and the shape and position of the lip 5 of the month are quite critical and should be so constructed and positioned that the air stream will be split by the mouth lip 5. A spring 7 with a fairly long arm 8 carries at one end a deflecting plate 9 which reaches down into the air stream and will vibrate when the stream hits it. The spring 7 has a forwardly bent section 10 and a rearwardly bent section 11 aligned with the arm 8 but not closely parallel to it. The section 11 of the spring serves as a clamping area by means of which the spring is held in place on the pipe 2. For this purpose the pipe 2 which may have a round cross section 12 (see Figure 4) has a flat outer top section 13 with a recessed section 14, in which the spring section 11 is positioned. A clamping collar 15 is slipped on the back of the tube from the end, over an increasingly enlarged section 16 of the tube, the clamping collar or band being similar in shape to the section 16 of the tube so that the clamping band will bind the spring section 11 tightly to the tube as the band is forced forward on the tube or pipe. The section of the spring emerging from the clamping section 10 is, as has been explained before, bent backwards in the section 10 to provide a backward section 17, which when pressed downward by the finger will raise the deflecting plate 9 out of the mouth of the whistle. The spring 7 may be provided in the section 3 with a slidable weight 18 which, by moving along the section 8 of the spring will vary the frequency of the spring and therefore the frequency of the beat or warble. The frequency of the beat in the tube may be varied by the plunger or piston 30 which may be a round pencil of the appropriate size or any type plunger, preferably with a fiat end. The plunger may be held secured in the pipe or tube for carrying purposes by means of a band 19 of rubber or the like slipped over the slotted end 20 of the tube to hold the plunger in place. The pipe 2 may also be provided with

side extending flanges

21 and 22.

These flanges may extend from the mouth piece back to the end of the spring at 17. The front sections 23 of the flanges may be attached to the mouth piece 1, while the rear portions 24 may be attached to the outside of the pipe 2. The flanges in the sections 24 have a longitudinal slot as indicated at 25 to permit the clamping band 15 to be slid over the end of the pipe.

Referring again to the mouth piece section it will be noted from Figure 2 that the cross section of the passage 4 is arcuate and formed between the arcuate block which y be dasapart of t e outh p ece. and the top portion 27 of the top wall. The mouth piece is provided with a shoulder, 28 which is made to fit and receive the end 29 of the pipe 2 withpreferably a forced fit not to be removed after it is once assembled, The ,pipe 2 may be made of a transparent plastic material and calibrated with graduations 30 which maybe in ,octayes or portions of octavesto provide a'frequency calibration for the end of the'pencil or plunger30 in .its position in and out of the pipe. The whistle may be carried in a'pocket by a clasp or clip 31 attachedto the mouth piece just below the front end. e

As indicated in Figures l through 4, the whistle may, for the most part, be rounded in form with a top flat section towards the end to fit the shape of a flat spring. ,I-Iowever,,the shapeof the spring at the clamping position may also be made arcuate and in this case the clamp- ..ing band will be made circular and the whole pipe can be made in the same form with the use of a forced fit ciamping bandor a slight taper in the end section of the pipe on the external surface so that the spring can be held .,tightly in its position. This arrangement is shown in Figure 11 where the section of the pipe is indicated .at 32, .the arcuate clamping section of the spring at 33 and the clamping band at 34. The springmay be gradually flattened out with the first reverse band section 35 of a slightly less curvature than the section 33 and the top sec- -,tion 36 of the spring completely flat. The band 34 may be provided with a slight recess to receive the spring secxtion 33 and it will be notedthatall of the circular sections are concentric with a central axis of the pipe.

Intheoperation of the modification shown in Figures --1 to 4 the operatorblows into the whistle through the -mouthpiece 4, the air'stream following in the direction of the arrow A hitting the lip of the mouth and also -:the deflecting plate 9. ,Part of the air jet continues down the pipe in the direction of the .arrow B and part goes out through the mouth piece setting the deflecting plate 9 and the spring section 8 in vibration. The frequency of the vibration of the spring 8 is established by its length, a the material of which it is composed and its weight distribution governed by the .position of the adjustable slider 18 on the spring. This slider may be set in the desired position as indicated by calibration on the face of the spring or by the experience of the operator. The vibration of the spring with the deflecting plate reach into the mouth of the whistle in the region of the air jet will I cause a warble in the note at a low frequency dependent upon the characteristics as set forth above. If it is desired to omit the warble during the blowing of the whistle, 'the end 17 of the spring may be pressed-down which raises the forward end of the spring and the deflecting plate 9 away from the mouth whereupon a pure note will be obtained dependent upon the position of the plunger in the pipe. To operate the plunger 3 readily the rubber band 20 may be removed. Both the plunger 3 andthe end of the spring 17 may be operated during the blowing of the whistleso that a note can be obtained varying in pitch and having a warble which may be omitted momentarily. This will supply a characteristic bird note.

Bird notes are, in general, composed of a sound having a resonant pitch but not particularly a pure pitch which may be varied over a frequency range together with a warbling of the note which, in some cases may be varied by the bird. In the case of some bird calls, both a modu- :lated and un'modulated note is used. The embodiment of the invention which has been described above produces means, for simulating these features of thebird calls.

- However, at times it is desired to vary the pitch'or beat frequency of the warble while the call is being made. To "do. this, in Figure l the weight 18 would have to be moved ;pwithout damping thevibration of. the spring. This is more readily accomplished in the modifications shown in Figures 5 and 6 in which other advantageous features are also included. In this case the mouthpiece 1' is similar to the mouthpiece shown in- Figurel with the exception of a small projecting catchS"! at the bottom of the mouthpiece to en age an end 38 of the spring 39 which is .used to tension the slide clamping collar 40- which'rnay be moved back-and forth along the pipe 2 while playing. The collar 4%) may besquare in section with an enlarged 1 base ll and a smaller head base 42, the collar tapering at the sidesas indicated by the side sections 43, Figure 6,. The; spring 391 is a; leafspring with a sectiondd contacting the lower face 45 of the pipe 2 and an overhang- "press against the forward end of the base 41.

' collar.

4 ing end 46 coming up against the rear edge 47 of the The lower part'ot' the 'spnn' is'iies 'agairist'the inner lower section 41 of the collar and is bent over the forward end as indicated at 49. The spring is so tensioned as to provide a space between the lower section 49 of the collar and the lower face of the tube. The upper section forming ,the head 42 is provided with a longitudinal slot 50 in the center of which are opposing knife edges 51 for gripping the spring 52 in an exact position. The grip of the knife edges 51 act as a clamping means on the spring 52, and, therefore, as the ad justable collar 4i} is moved back and forth, the length of the spring from the position of theclamping knife edges to the deflecting plate end at 53, is increased and decreased correspondingly. There'arend of the spring is held in place by a forced fit collar 54 fitting over the back end of the spring and clamping the end 55 of the spring which may have a pressed out boss 56 pressing jfirmly into the clamping collar. The'clam'pingf'collar 54 may be provided with an inwardly pr'ojecting'flan'ge 57 projecting against the plunger 58 with a suflicientjt'ol- 'eranc'e to allow it to be moved'back and forth. The forward end of the plunger 58 has a sliding fit, as indicated at 59, on the inside of the tube with a shoulder, as indicated at 60,'for which the inwardly projecting flange or ,arm 57 acts as a stop. In the innermost position'a' depression 61 in the top of the plunger 58 near its outer 'edge locks in place with a V-shaped latch 62 formed'in .thespring section 55 beyondthe clamping end. When not in use, therefore, the plunger may be pushed all the 'way in topermit the spring latch 62 to engage the depressiodfil. Similarly the collared may also be locked in position by advancing the collar until the spring latch 38Jengag'es' the projection 37 at the mouthpiece of the I whistle. When the collar is in this position the front edge 63 of 'the head 42 comes upagainst the back of the deflecting plate 53 and acts as a rest or support for the forward end'of the spring.

r A flange 64 may be pro- .vided at the sides of the spring to furnish further protection for it under all conditions.

In the operation of the modification shown in Figures 5 and 6 the plunger may be rnQVed forward and backvward as des1red. A calibration of frequency'or pitchas "indicating the pitch or frequency of the note.

indicated at65 may be provided on the walls of the tube corresponding to the front edge of the plunger or piston In order .to change the frequency of the warble, the

hco llar 40 may be moved back and forth while blowing. If the length of the section of the spring to the deflecting plate is mcreased the beats of the warble will be (decreased and if the length is decreased the beats of the warble will be increased per unit time.

Inorder to omit the warble it is necessary simplyto This will raise and tilt the spring upwards so that thedefiecting plate 53 will be drawn clear of the mouth in the tube. ,It will be noted from the description, above that the .;change of frequency of the warble and the omission or inclusion, of the warble is all accomplished without'inter- .rupting the playing. The change of pitch or note will also be accomplished, or course, without stopping.

, The instrument shown, therefore, in Figures 5 and 6 can readily be used as a musical instrument in an orchestra, 'or otherwise, providing desired characteristic changes as the playing of the orchestration may require.

7 As a toy for the amusement of children, an ornamentation of a bird may be applied to the whistle. This'form of invention is shown in Figures 7, 8, 9, and 10. The

whistle in this case may be made longer than in the other forms if des1red to give the child blowing the whistle a better opportunity to look at the bird. The bird, in

' Figure 7,'is mounted on the top side of the whistle with the feet 71 preferably just forward of the mouth 72.

The air. passage 73 may, as in the other embodiments of the invention, direct the air jet into the mouth 72"and against the lip 74. The deflecting plate 75 may eittend into the mouth 72 as previously explained and the'sp'ring 77 may extend upwards into the bird through an opening 76 in its bottom side just over the tube to the eye.

;The spring in this region may carry small eye plates ;78 extending upward on either side which are seen through aligned eye openings 79 in the bird. Thespring may also be bent forward in the section 80 extending through the bird forming the lower beak. Fromjthis position the spring is bent backwards as indicated at 81 through the length of the bird emerging from a slot 82' in the rear of the bird at which point a reverse bend 82 may be formed in the spring to provide a clamping section 83 which may be held in position by the side flanges 84 extending up from the body of the whistle which may have internally projecting bosses 85 or be pressed against the sides of the spring in the end of the section 83 to hold it in place.

At the end of the rear section 86 of the portion 81 of the spring, the spring may have a slightly upward bend providing a region which may be pressed down by the operator to raise the deflecting plate 75 clear of the mouth 72. In the operation of the device of Figures 7 to inclusive, the vibrating deflector plate and spring will cause the birds eyes to move as well as the lower beak and provide an animation to the bird as well as a warbling note. The operation of the modification of Figure 7 may use a plunger or piston for varying the pitch of the note and it also may be provided with a slidable weight, as indicated in Figure 1 on the spring to provide an adjustment of beat frequency of the spring.

In the modification shown in Figures 12 to iuclusive the device is similar to the modification of Figure 7 except that the modification of Figure 12 is intended to be molded of plastic principally by injection molding in two parts which are cemented together along their joining edges. Figures 13 and 15 indicate this. As shown in these figures, there is a right hand element 90 and a left hand element 91. The joining line is at the bottom of the whistle in a shoulder as indicated at 92 at the corner 3 of the tube or pipe passage 93. The section 91 comprises substantially the left half of the whistle with a top cover 94 extending over the pipe 93 into a slot 95 in the wall 96 of the right hand half 90 of the device.

The right hand half 90 on the other hand forms the 3 wall 97 of the pipe.

The whistle of Figure 12 is in the form of a log with a bird 98 which may simulate a Woodpecker standing on the log with its bill directed somewhat over the mouth 99 of the whistle. the center as indicated by the double line 100 and tr e vibrating spring 102 preferably has its deflecting plate 101 extending through a slot over the birds beak and projecting into the top of the mouth 99. The groove 95 in which the top wall 94 of the pipe rests extends the whole length of the whistle and so, also, the shoulder 92. These are the lines which are firmly cemented together as well also as joining lines 100 on the bird. The mouth 99 is recessed slightly into the

side walls

96 and 96 of the tube as indicated by the curves 103 and 104 (Figure 14). The air passage 106 through the mouthpiece 105 is confined within the dotted lines as indicated (Figure 14) so that the deflection plate 101 as it dips into the mouth will cut 011 sharply the air passing through the air passage 106 impinging against the knife edge 107 and produce thereby a sharp cutoff of the note which has the effect of making the warble very distinct.

It may also be noted in Figures 13 and 14 that the actual knife edge 107 extends only between the inner surface of the side walls since the edge 108 of the top wall is the full thickness all the way along the groove 95. The side wall 96 of the whistle above the pipe may be provided with one or more locking'flanges 109 locking over the top wall 94 of the pipe. The spring 102 carrying the deflecting plate passes through the middle of the bird which is hollow and is locked in place on the top wall of the pipe by means of an interlocking flange 110 extending from the side 90 in the wall section 96. This flange 110 engages a recess 111 in the wall 96 and holds the spring base 112 firmly in place between the top wall 94 of the pipe and the flange 110. An opening at the top of the bird not shown in the figures, but just over the bend 113 in the spring, permits the spring to be pressed down at that point to raise the deflection plate 101 out of the mouth as in the other modifications when that is desired. A plunger 113 may be operated in and out of the end of the pipe.

In front of the clamping section there is provided a saliva block 114, which has deflecting walls extending diagonally downward and backward from the center to 8 permit any saliva which may gather in the whistle to flow off through the opening 115 at the back of the birds feet. The construction indicated in Figures 12 to 15 permits the whistle to be molded of any suitable plastic material either by compression or injection molding and 85 for various utilitarian purposes,

The joining line of the bird may be at 6 thereby facilitates the low cost of manufacture with all the merits and attractiveness that the whistle could have with more expensive and elaborate construction.

In the arrangement indicated in Figures 16 and 17 the whistle 116 may be made of any suitable material, plastic or otherwise and differs from the modifications previously described chiefly in the use of a pair of

springs

117 and 118 with deflecting

plates

119 and 120 respectively which do not dip into the mouth 121 of the whistle so that while the springs will vibrate, the air jet in the mouth is not interrupted and therefore no warble will be produced at the mouth. The

springs

117 and 118 may be mounted to the top wall 122 of the whistle and may have cuplike member 123, etc., attached to the springs at various points. These cuplike members are valves and cover and uncover holes 124 through the top wall 122 of the whistle. When air is blown through the mouthpiece 125 and hits the deflecting

plates

119 and 120, the springs will vibrate at different frequencies dependent upon their length and the cups will cover and uncover the holes in the tube changing the pitch effect and tone of the whistle in a regular and timed sequence. The whistle may be provided with a top cover 126 as a protection only for the spring and may, therefore, permit air to escape which comes out of the tube 127.

In the modification shown in Figure 18 the whistle is made in the form to simulate a gun, 128. The gun is provided with a mouthpiece 129 in the rear through which the whistle may be blown. On the top of the gun is mounted the vibratory spring 130 which has a deflecting plate 131 dipping into the mouth 132. The spring 130 is retained by a slidable collar 133 to which the trigger 134 is attached at the rear. Between the handle 135 and the trigger 134 is a helical spring 136 wrapped around the barrel 137 of the gun which acts, of course, as the pipe for the whistle. As the trigger 134 is pulled against the helical spring the deflecting plate 131 will enter the mouth 132 and create the warble effect when the whistle is blown. If the trigger is released the spring will be forced back to its original At the end of the gun is a small projecting boss 138 to prevent the collar 133 from coming free from the barrel. A plunger 139 may also be provided to be moved in and out of the pipe and this plunger may be recessed throughout its length except at its ends so that it will be retained in the barrel 137 by the proectmg pm 140 on the inside of the pipe at the open end. The operation of Figure 18 is quite readily understood. By workmg the trigger back and forth the warble may be created or eliminated at will. In the arrangement lndtcated in Figure 19 a double effect may be obtalned including the creation of the warble at will simultapeously with the change of the pitch of the note. For this purpose the gun 141 comprises a bent tube 142 WhlCh acts as the handle of the gun. The tube 142 is formed in a U shape and is sufliciently flexible so that the center opening 143 of the U can be made smaller and larger slmply by squeezing the handle of the gun with the finger of the trigger 144. At the top of the gun there is mounted a spring 145 which is attached to the barrel 146 and the gun in the section 147 of the spring. The spr ng extends backward to the handle and is provtded with a deflecting plate 148 which may engage the month 149 when the handle is squeezed. Air, then blown mto the mouthpiece 150, will vibrate the deflecting plate andsprmg 145 and cause the plunger 151 in the open section 152 of the tube to move up and down. The plunger 151 is made to do this through the rod 153 which is attached to the spring 145 between its clamping positron and the deflecting plate. On steel spring, weight 154 may be magnetic to maintain its position after each adjustment to adjust the vibratory frequency of the spring.

By blowing through the mouthpiece and causing the deflecting plate 148 to engage the mouth 149 the spring will vibrate causing a warble and at the same time a change in pitch. The deflecting plate may be moved almost up to the mouth so that it vibrates without deflecting the air jet in the mouth as in the modification of Figures 16 and 17 in which case the spring will 0 vibrate to oscillate the plunger 151 and cause a variable pitch while if the spring remains in the position shown in Figure 19 a note of the same pitch will be produced.

Various forms and modifications of the invention have been illustrated in the drawings. These may be used as, for instance, toy- 7 and amusement devices, musical instruments, bird-walls and whistles, and, in large constructions, as adjuncts to organs and for other industrial purposes. 'ln this respect the whistle may be operated both by an air-blast or by other means as by a steam blast. ln 'p'articular, where a distinctive note or combinations of I notes are desired 'to 'be produced, the device described in the present 'invention may successfully be usedforthat purpose.
