Description

D. P. PERRY.
. ELEOTRIO BURN.
APPLIUA'TION FILED NOV. 3, 1905' and an electric buzzer or circuit-breaking device, spring means for connecting said circuit breaking device with said diaphragm for communicating vibration thereto for the purpose of vibrating the column of air within thehorn. I
2. In a horn, the combination of a thin sheet-metal member made hollow With a flaring forward end and a slightly enlarged mouth or rear end, a flexible metal diaphragm closing the mouth of said member, means for preventing the vibrations of the diaphragm from being mechanically communicated to said sheet-metal member, and means back of the diaphragm for mechanically vibrating the same. 51 In a horn, the combination of a diaphragm, an electric buzzer or circuit-breaking device, and a spring connection between said diaphragm and the armature of said electric buzzer or circuit-breaking device.
4. In a horn, the combination ofa diaphragm,'an electro-magnet, a spring-mounted armature for said electro-magnet', circuitcontrolhng contacts operated by said armature, a spring connecting said armature with,
said diaphragm, and a weight carried by said spring.
5. In an electric alarm device, a horn, a diaphragm arranged in operative relation thereto, an electromagnet, an armature influenced by said electromagnet and an elastic intermediary part fixed on the one hand to said diaphragm and on the other hand to said armature, whereby the vibrations of the armature are mechanically transmitted to the diaphragm in such a manner thatthe vibrations of the diaphragm may differ from those of the armature.
6. In an electric alarm device, ahorn, a diaphragm arranged in operative relation thereto, an elector-magnet, an armature infiuenced by said electromagnet and a spring ture attached to said lever and influenced .by said electromagn'et, and a spring fixed on the one hand to said diaphragm and on the other hand to said lever, whereby vibra? tions of the armature are mechanically transmitted to the diaphragm in such a manner that the vibrations of the diaphragm may differ from those of the armature.
