Benefits of technology

In view of the above-mentioned disadvantages of the prior art, it is an objective of the present invention to provide an apparatus which can quickly identify and extinguish a fire before it has a chance to spread.
A further objective is to provide an apparatus which can accurately pinpoint and extinguish a fire whereby the fire extinguishing activity is, restricted only to the immediate vicinity of the fire thereby reducing damage.
A further objective is to provide a fire extinguishing apparatus which is reliable yet inexpensive.

Problems solved by technology

Because these types of heat sensors are slow and inefficient, by the time the fire is detected it has usually spread over a large area causing injuries and property damage before it is extinguished.
Additionally, a fire is much more difficult to extinguish after it has spread then at its inception.
However these types of detectors are used commonly merely to set off fire alarms and not to extinguish the fire itself.

Embodiment Construction

Referring now to the drawings, and more particularly FIGS. 1 and 2, an apparatus 10 constructed in accordance with this invention includes a base 12 mounted on a ceiling 14 and a turret 16. The turret 16 includes a generally cylindrical housing 18 open at the top. A motor 20 secured inside housing 18 is used to rotate the turret 16 about a vertical axis X--X. For this purpose, motor 20 has a shaft 22 terminating in a toothed gear 24. Base 12 is provided with a stationary ring 26 having radially inwardly extending teeth 28. Teeth 28 engage gear 24 so that as the shaft 22 is turned by motor 20, the turret 18 rotates with respect to the base.

An arm 30 is mounted on housing 18 by a horizontal shaft 32. Shaft 32 also supports a toothed gear 34 disposed inside housing 18. Also within housing 18 there is provided a second motor 36 with a shaft 38 and a gear 40. Importantly, gear 40 has teeth 42 disposed at an angle and engaging the toothed wheel 34 such that as the gear 40 is turned by mot...

Abstract

An automated fire extinguishing apparatus includes a turret with a nozzle connected to a water supply. A plurality of sensors are used to detect a fire monitored by the apparatus. The signals from the sensors are used to aim the nozzle toward the fire and to initiate water ejection therefrom. After the fire is extinguished the water is turned off.

Description

BACKGROUND OF THE INVENTION1. Field of InventionThis invention pertains to an automatic fire extinguishing apparatus, and more particularly to an apparatus which locates a fire in a room and directs a stream of water or other agent from a nozzle at the fire for extinguishing it.2. Description of the Prior ArtAutomatic sprinkler installations are common in both residential and commercial establishments and are frequently mandated by local fire codes. However these sprinkler installations consist merely of a plurality of water nozzles set off by mechanical heat sensors. Because these types of heat sensors are slow and inefficient, by the time the fire is detected it has usually spread over a large area causing injuries and property damage before it is extinguished. Additionally, a fire is much more difficult to extinguish after it has spread then at its inception. Fire detectors are also known which detect a fire by using heat and / or light sensors. However these types of detectors are...
