SELF OPERATING FIRE EXTINGUISHER.

APPLICATION FILED SEPT. 5, 1911.

JOHN W. HUGHES, 0F CAMERA, PENNSYLVANIA.

SELF-OPERATING FIRE-EXTINGUISHER.

To all whom it may concern:

Be it known that 1, JOHN W. HUGHES, a citizen of the United States, residing at Cambra, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Self-Operating F ire-Extinguishers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a self-operating fire extinguisher and has for one of its objects the provision of a device of this character, which will automatically extinguish a fire when the flames come in contact or close proximity thereto.

Another object of this invention isthe provision of a receptacle containing a fire extinguishing chemical, which is adapted to be dispensed from the receptacle by an exposive when ignited by the flame of the fire so that the chemical will come in contact with the flame and produce a gas, which will smother the flame.

Another object of this invention is the provision of a self-operating fire extinguisher of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a side elevation of a self operating fire extinguisher constructed in accordance with my invention,

Fig. '2 is a vertical sectional view of the same, r

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

Referring in detail to the drawings, the numeral 1 indicates a receptacle which may be of any desired shape or formation and preferably of cylindrical formation as clearly shown in the drawings, having its upper end flared as shown at 2 for the purpose of receiving a cover 3, which fits loosely within 7 Specification of Letters Patent.

the open end of the receptacle. The receptacle has formed adjacent its upper end, oppositely disposed ears 4 to which is connected a bail 5. The bail 5 is bent to form an eye 6, that may receive a nail, .hook or other suitable support, whereby the device may be suspended within a room, building or at a suitable point upon an automobile or vehicle. i

The casing 1 is provided adjacent its upper end with oppositely disposed openings 7 which receive the arm portions of a T- shapedtube 8, that has its leg portion disposed downwardly within the casing. The T-shaped tube 8 is constructed from paper or other suitable material and has formed upon the lower end of its legportion, a cartridge receptacle 9 that rests upon the bottom of the casing 1. The cartridge casing 9 is filled with powder or other explosives as shown at. 10, which has in communication therewith, a fuse 11, that extends upwardly through the leg-portion of the T-shaped casing 8 and outwardly of each of the arm portions thereof and through the holes 7. The arm portions have their outer ends closed by caps 12 that are constructed from celluloid or other suitable material, which protect the ends of the fuse 11 under ordinary circumstances, but if they come in contact with the flames of the fire, they will readily burn and ignite the fuse 11. The fuse 11 is of the type that contains explosive such as powder or the like, which will create small explosions as the same burns.

A fire extinguishing chemical 13 of any desired kind which will, when coming in contact with flames of a fire, produce a gas capable of smothering the flames, is placed within the casing 1 about the tube 8 and cartridge 10, as clearly shown in Fig. 2. The device is then suspended by the bail 5 and in case of fire,the caps 12 ignite, which in turn ignite the fuse 11. As the fuse 11 burns, a small explosion is caused throughout the length of the fuse, which will dispense the fire extinguishing chemical 13 outwardly of the casing 1 at its upper end and as it comes in contact with the flames, will produce a gas capable of smothering the flames and puts out the fire. As the fuse 11 burns and explodes throughout its length, it ignites the cartridge 10, which explodes and dispenses the remaining contents of the casing 1 from its upper end or if the explosion is of sufficient strength it will destroy the casing form a hand 'ri 15. which will aid in carrying or t'ansporting the casing from one point to another by placing the other hand about the bail 5.

'While it have shown and described the preferred embodiment of my invention, it will he understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.

'What is claimed is:

1. A fire extinguisher comprising a casing having oppositely disposed openings, a T-shaped tube located within the casing and having its arm portions disposed in said openings an explosive cartridge located within the casing, a tire extinguishing chemioepending entireiy on the.

eel locate within said casing, and a fuse located within said T-slraped tube and connected with the explosive cartridge and extending through the horizontal arm portions to be ignited by the flames of a fire to explode the cartridge and dispense the chemical A self operating fire extinguisher comprising a casing, an explosive cartridge therein resting on the bottom of said casing, a bail for supporting said casing, a T-shaped tube located within said casing and having horizontal arm portions, a fire extinguishing chemical located within said casing, a fuse located within the "it-shaped tube and connected with the explosive cartridge and extending through the horizontal arm port-ions and ignitihle caps normally closing, the ends of the horizontal arm portions to protect the ends of the fuse.

in testimony whereof i aiiix my signature in presence oi two witnesses.
