housing having an opening injt for deli vet ing the sound, and vanes fastened to said housin radii t ereof in position to be struck by the air emerging from the sound producing I device.
3. A siren having a rotor, a stator, a (lranr- 1 bered h sing inclosing the stator, said housing being rotatable, and having internal vanes adapted to be impinged by the air emerging from the rotor and'stator for driving is e housing, said" housing havin a horn communicating with the inside 0. it and leading away from the'housing toward the side thereof. 4. A siren having a stator, a rotor within the stator, an imperforate chambered rotatable housing inclosing the rotor and stator, the space within the housing being much eater than the space occupied by the rotor and stator, and the housing being somewhat spherical in form; vanes fastened. to the in nor walls of the housing, said vanes being arranged at an angle to the air currents emerging from the rotor and stator, and a duct communicating-with the inside of the housing and leading offtoward one side thereof for amplifying and directing the sound.
5. A sirenhaving a stator, a rotor arranged with a vertical axis and having sound apertures in the peripheral Walls, a somewhat s herical housing inclosihg the stator and Being spaced therefrom at the sides and top, vanes secured to'the inside of the housing and rising upward above the top ofthe stator, said vanes being arranged at an oblique an le with respect to the radii of the housing, t e housing having an opening at the top and a horn leading laterally from said openin for directing the sound.
6. In com ination, a siren having a rotor revoluble about a vertical axis, a motor having a shaft for supporting and revolving said rotor, a stator inclosing said rotor, the stator and rotor having sound apertures in the peripheral walls, a somewhat spherical hens and arranged at an angle to the incense ing placed around and over the stator." and provided wit internal vanes arranged 1101i radially, the housing having an opening at the top approximatelyin line with-the axis of the rotor; means for supporting the housing and permitting it to rotate about a ve'rti cal axis coincident with the axis of the rotor, the housing having an openin in itfor the escape of sound, and a souu duct leading from said 0 ening.
7. In com ination, a siren having a rotor, a stator inclosing the rotor, the rotor having a vertical axis, supporting means for the stat-or, a housin inclosing the stator and rotor, an anti-friction bearing for the housing concentric with the rotor, vanes on the inside of the housing arranged non-radially for deflecting the air emerging from the rotor and stator, and thereby causing the housing to revolve,-said housing havin an opening in it for the emission of 501111 8, In combination, a siren having a rotor, a stator .iuclosing the rotor, the rotor having a vertical axis, supporting means for the the stator and rostator, a. housing inclosm tor, an antl-frict on hearing tor the houslng concentric with the rotor, vanes on the mside of the housing arranged non-radially for deflecting the air emerging from the rotor and stator, and thereby causing the hens ing to revolve, said housing having an opening in it for the emission of sound;-s'a1d opening being locatedat the center of the top of the housing, and having a horn leading laterally from it for amplifying and di-- rectiiig the sound.
9. e n combination, a revoluble megaphone,
siren having a stator and a rotor having sound holes in the sides through whichai-r is forced by the centrifugal action of the rotor, and means adapted to be actuated by the air emerging from the sound holes for revolving said mega hone.
