8 Claims. (Cl. 46-52) This invention relates to a novel sounding toy intended to be propelled through the air and including parts forming a siren, the rotor of which is driven by the impulse of air passing through the siren so that the siren is in effect an impulse turbine.

, More particularly, it is an aim of the present invention to provide a siren-type sounding toy of extremely simple yet unique construction capable of producing siren tones of varying pitch depending upon the speed of movement of the toy through the air.

A further object of the invention is to provide a toy of the aforedescribed character composed of a minimum number of parts, which may be very economically manufactured and yet which will be suiciently rugged and durable to withstand rough use.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is an end elevational view looking toward the forward end of the toy;

Y Figure '2 is a side elevational view thereof showing an intermediate portion of the toy in section, along a plane as indicated by the line 2-2 of Figure 1;

Figure 3 is a longitudinal sectional view taken substantially along a plane as indicatedV by the line 3-3 of l Figure 1; l

`Figures 4 and 5 are cross sectional views through the toy, taken substantialy along planes as indicated by the lines 4-4 and 5 5, respectively, of Figure 2, and

Figure 6 is an enlarged fragmentary detailed sectional view of a portion of the rotor, taken substantially along a plane as indicated by the line 6-6 of Figure 4.

Referring more specifically to the drawing, the toy jnitsV entiretyhis designated generally 8. 'The toy 8 is elongated and of substantially rocket-shape, and includes a forward section, designated generally 9, and a rear section designated generally 10. The forward portion of the toy 8 constitutes a nose 11 and the rear portion thereof constitutes a tail 12 which is somewhat longer than the nose 11. The toy 8 also includes an intermediate portion forming a siren, designated generally 13.

The nose 11 extends forwardly from a front wall 14 of the stator or casing 15 of the siren 13 and said nose 1'1 tapers to a point 16 at its forward end. The nose 11 is composed of four corresponding fins 17. Each of the fins 17 tapers in thickness from the axis of the nose 11 to the outer edge 18 of said iin and each n 17 also tapers in thickness toward the forward end 16 of the nose, and the outer edges 18 of the fins converge with one another and merge at the point 16. A cap 19 formed of a cushioning material such as rubber is shown detachably mounted over the point 16 of the nose 11 in Figure 2. The cap 19 can be utilized to protect the point from damage and to prevent the point 16 from damaging an object or person which might be struck by the toy 8, while said toy is in flight.

The tail 12 is likewise preferably formed of four cortates arent r'ice responding fins 20. The fins 20 are preferably of uniform thickness and width from end-to-end of the tail 12 and are formed integral with or suitably secured to and extend rearwardly from a substantially Hat rear wall 21 of the casing or stator 15.

The front wall 14 has a rearwardly extending annular tapered flange 22 and the rear wall 21 has a forwardly extending annular flange 23 which is ared outwardly and the forward edge of which abuts the rear edge of the flange 22 to form the annular side wall 24 of the stator or casing 15 which is preferably tapered rearwardly, as seen in Figures 2 and 3. The rear edge of the flange 22 is preferably provided with pins 25 which extend rearwardly therefrom and which snugly engage in forwardly opening sockets 26 of the ange 23 for connecting said flanges and for assembling the casing or stator 15. The wall 14 and flange 22 together with the nose `11 form the forward section 9 of the toy body and the rear wall 21, its ange 23 and the tail 12 constitute the rear section 10 of the toy. The flanges 22 and 23 have outwardlyV opening notches which are disposed in registration when the casing 15 is assembled, to form the circumferentially spaced slots 27 of thestator wall 24, as best seen in Figures 3 and 4. v

The siren 13 also includes a rotor, designated generally 28, including a disc 29 which is disposed within the casing 15,` adjacent the rear wall 21. A spindle 30 extends through the central portion of the disc 29. The centers of the front and rear walls 14 and 21, respectively, are provided with inwardly opening depressions forming aligned bearings 31 which extend into central portions of the nose 11 and tail 12. The ends of the spindle 30 are journaled in said bearings 31 to rotatably mount the rotor 2S, of which the disc 29 forms a part, within the stator 15. Said rotor also includes an annular liange 32 which extends forwardly from the periphery of the disc 29 and which is ared toward its open forward end. Said open forward end 33 constitutes the open forward end of the rotor 28 and is disposed within the casing 15 behind and adjacent the front wall 14. The liared annular wall or flange 32 is provided with cir- Vcumferentially spaced slots 34 which move into and out of registration with the slots 27 when the rotor 28 is revolved. The disc 29 whichforms the rear wall of the rotor 28 has a plurality of portions struck therefrom which are bent inwardly and forwardly to form vanes 35. The vanes 35 ar'e secured to the disc 29 along corre spending radial edges thereof, Yand said vanes 35v all extend in the same direction from the disc 29 and are uniformly pitched. The vanes 35 form openings 36 in the disc 29. The front wall 14, between the fins 17, is provided with openings 37 which open into the rotor 28 through the open front 33 thereof, and the rear wall 21 is provided with openings 38 between the fins 2t? and which align with the openings 37.

The toy 8 is of projectile shape and may be propelled in any suitable manner through the air. It will be readily obvious that the nose 11 is substantially heavier than the tail 12 so that said nose will constitute the leading end of the toy when in ight. Consequently, air will enter the siren 13 through the entrance openings 37 in the front wall 14 and will pass into the rotor 23 through its open front 33. The air will impinge against the rotor vanes 35 to cause the rotor to be revolved clockwise as viewed from front to rear of the toy, or as seen in Figure 4. The plurality of vanes 35 will cause the rotor 28 to be revolved at a high speed, and the air will be deliected by the vanes 35, due to centrifugal force, outwardly through the slots 34 and thence outwardly through the casing slots 27. The puffs of air escaping through the slots 34 and 27, as the slots 34 are momentarily in registration with the slots 27, will produce tones asaasvi the pitch of which will rise and fall as the speed of rotation of the rotor 28 increases and decreases. Additionally, some of the air will escape through the openings 36 outwardly through the rear wall openings 38, since the air will be to some extent confined within the siren casing i5' due to the rearward tapered construction thereof.

The rocket-shapedV toy may be propelled in any suitable maner in free flight through the air as a projectile to operate in the aforedescribed manner,'or said toy may be held by a tethering line 39 and swung in a circular path. An end of such a line 39 is shown in Figure n3 having branch portions 40 which are secured to` one of the nose fins V13 and one of the tail fins 20 through openings 41 thereof. The toy 3 may also be supported by a rigid bar forming a handle 42 an end of which may be secured by a fastening 43 tov the aforementioned tail fin 2t) through the opening 41 thereof, so that the toy 8 may be held by the handle 42, as illustrated in Figure 2, out of the window of a moving vehicle, for example, to be actuated by the movement of air relative to the toy, it being understood that the nose 1E.. will be disposed to face forwardly.

Various modifications and changes are contemplated and may be resorted to, without departing from the function or scope of the invention as hereinafter defined by the appended claims.
