Abstract

A combination whistle (1) having a mouthpiece (2) leading to bulbous whistle portion (3) which is gripped by hand when blowing into the mouthpiece. Mouthpiece (2) is common to trill chamber (4) and two pea-less chambers (5 and 6), chamber (6) being located under chamber (5).

Claims

1. A whistle (1) having a pea-less chamber (5,6) and a chamber (4) including a moveable element (4c) associated therewith, such as a pea or rotatable member, said chambers (4, 5, 6) having a common mouthpiece (2) or being positioned so as to be able to be blown into substantially simultaneously by a user.

2. A whistle (1) as claimed in claim 1 in which the moveable element (4c) is positioned inside the associated chamber (4).

3. A whistle (1) as claimed in claim 1 or claim 2 in which the moveable element (4c) is able to repeatedly partially block and open a vent (v) or opening of the associated chamber (4).

4. A whistle (1) as claimed in claim 3 in which the vent/opening (v) has a splitter edge (5b) of a curved, straight, rectangular or square shape or which is undulatory, mouth or top-lip shaped.

5. A whistle (1) as claimed in any one of the preceding claims in which the chamber having a moveable element (4c) associated therewith is a trill chamber.

6. A whistle (1) as claimed in any one of the preceding claims provided with a plurality of pea-less chambers (5,6).

7. A whistle (1) as claimed in claim 5 or claim 6 when dependent therefrom in which the trill chamber is to one side of the mouthpiece (2) and at least one pea-less chamber is provided to the other side of the mouthpiece (2).

8. A whistle (1) as claimed in claim 7 in which two pea-less chambers (5,6) are provided one above the other to one side of the trill chamber (4).

9. A whistle (1) as claimed in claim 6 including one trill chamber (4) located in between two pea-less chambers (5,6).

10. A whistle (1) as claimed in claim 9 in which all the chambers (4, 5, 6) will vent upwardly of the whistle (1).

11. A whistle (1) as claimed in claim 9 or claim 10 in which said trill chamber (4) is located centrally of the mouthpiece (2) with a pea-less chamber (5,6) on each side of the trill chamber (4).

12. A whistle (1) as claimed in claim 11 in which the pea-less chambers (5,6) are arranged symmetrically of the trill chamber (4).

13. A whistle (1) as claimed in claim 5 or any claim dependent therefrom in which the width of the trill chamber (4) is about twice the width of the pea-less chamber (5,6), or of one of the pea-less chambers (5,6).

14. A whistle (1) as claimed in claim 6 or any claim dependent therefrom having two pea-less chambers provided in the whistle (1), said chambers (5,6) having discorded frequencies and/or one of the pea-less chambers (5,6) being arranged to exhaust upwardly of the whistle (1) with the other being arranged to exhaust downwardly of the whistle (1).

15. A whistle (1) as claimed in any one of the preceding claims provided with a moveable element (4c) in the form of a rotatable member (4′

a), rather than a pea, said member (4′

a) being a roller or sleeve, or in which said moveable element (4c) comprises a flap or a membrane, which membrane may be curled.

16. A whistle (1) as claimed in claim 15 in which the roller or sleeve (4′

a) is on a central web (4′

c) inside the associated chamber (4).

17. A whistle (1) as claimed in any one of the preceding claims in which the moveable element (4c) is of plastics.

18. A whistle (1) as claimed in any one of the preceding claims able to produce a loud versatile multi-frequency sound.

19. A whistle (200) as claimed in any one of the preceding claims in which the sound characteristic is adjustable, variable or differently presettable.

20. A whistle (200) as claimed in claim 19 in which the size of at least one of the chambers (201) is adjustable.

21. A whistle as claimed in claim 20 in which the length of said adjustable sound chamber (201) may be varied by an (axially) advanceable and retractable plunger (202).

22. A whistle (300) as claimed in claim 21 in which there is a rotational or screw thread adjustment (303) to advance or retract the plunger (302) in the chamber (301).

23. A whistle (400) as claimed in claim 19 in which one or more holes (H) is/are provided in said one chamber (401), which hole or holes (H) can be plugged or covered by a (slidable) cover (C).

29. A sound produced or substantially producible by a whistle (1) as claimed in any one of the preceding claims or substantially similar to said sound.

31. A method of refereeing including blowing into a whistle (1) as claimed in any one of claims 1 to 28 or utilising a sound as claimed in claim 29 or claim 30 or a sound substantially similar thereto or a sound characteristic similar to prototype No.9 shown in FIG. 10a of the accompanying drawings.

32. Use of a sound as claimed in claim 29 or claim 30 in a sports event or use of a whistle (1) or apparatus capable of producing such a sound.

24. A whistle (1) substantially as herein described with reference to FIGS. 1 to 3 of the accompanying drawings or when modified substantially in accordance with FIG. 4 or FIG. 5 of the accompanying drawings.

25. A whistle (1) substantially as herein described with reference to FIGS. 6 to 8 of the accompanying drawings.

26. A whistle (1) or sound generator having a sound characteristic, or a sound characteristic, substantially as shown as that of prototype No.9 in FIG. 10a of the accompanying drawings or which is more like that of prototype No.9 than that of Tornado 2000 No.7, or of Acme Thunderer (small) No.7.

27. A whistle (1) substantially as herein described with reference to FIGS. 11a and 11b, or 12a and 12b, or 13a, 13b and 13c of the accompanying drawings.

28. A whistle (1) having a pea-less chamber (5,6) and a chamber (4) with a moveable element (4c) associated therewith, the arrangement being such that the chambers (4, 5, 6) can be sounded substantially simultaneously by the user.

30. A sound produced or substantially producible by a whistle (1) having at least one pea-less chamber (5,6) and at least one chamber (4) including a moveable element (4c) associated therewith, said sound being produced or substantially producible by blowing into said chambers (4, 5, 6) simultaneously.

33. A whistle (1) or sound generator adapted to produce an effective sound of about 70 to 84 dBA at a flow rate of about 12 to 13 liters/second with a sound of 11 dBA or above at a flow rate of about 120 liters/second or above.
