CHEMICALl FIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No. 321,161, dated June 30, 1885.
I Application filed May 18, 1885. (No model.)
' To all whom it may concern.-
Beit known that I, JOHN A. WAGNER, of Middletown, Butler county, Ohio, have invented a new and useful Improvement in Fire- Extinguishers, of which the following is a specification.
The invention relates to the class of fire-ex' tinguishers which comprises a bottle or other receptacle for the chemical,which bottle,when desired to operate automatically, is placed in condition for service by being suspended mouth downward from the ceiling or other selected part of the room to be protected, the said mouth being closed by a material which is fusible at a temperature but little in excess of the highest to which the atmosphere will reach apart from artificial aid.
The invention consists in substantially the following arrangement of parts, whereby the bottle,when in its normal condition, is sealed: The mouth of the bottle is provided Withametallic cap having a series of perforations around it near its junction with the shoulder of the bottle, and having anipple at its center, within which loosely slides a tube, which, extending into and the whole length of the bottle, terminates in an india-rubber tip or pad, which bears against the interiory end of the bottle. Secured to this tube, and within the cap above referred to, is a collar or piston, which, when the said padded extremity of the tube is rmly seated on the inner end of the bottle, as aforesaid, is interposed between the interior of the bottle and said orifices, and thereby prevents communication of said interior with the outer air. Said padded extremity of the tube is, in the normal condition of the bottle, held rmly against the end thereof, as aforesaid, by means of a capsule, which, surrounding the said nipple, is temporarily fastened thereto by soft solder or other cementing substance such as will melt at any heat notably above the highest ordinary atmospheric teinperature-such,for example, as 150 Fahrenheit. On being subjected to any such excessive or unwonted temperature the melting of the solder permits the said capsule and its support-ed air-inlet to drop, in obedience in part to the gravitation of the parts and partly to the outthrust of the im prisoned gases, and in lso doing permits entrance of air th rough the tube above the liquid contents,which thus vescape freely through the cap-ajutages in the form of spray or line jets unimpeded by the entering air.
In. the accompanying drawings, Figures l and 2 are vertical sections of my apparatus in its normal and its discharging conditions, respectively. Fig. 3 represents certain portions in perspective.
A is mybottle, preferably of glass and of the represented approximately cylindrical shape, and having depressions a a' diametrically opposite each other, near the closed end of the vessel, to receive the ends of a bail, B, of spring-wire, so as to enable suspension of the apparatus in the inverted position shown.
rlhe screw-threaded neck G of the bottle receives the correspondingly-threaded cylindrical cap D, preferably of metal. The said cap has, alittle below its threaded portion d, a horizontalseries of orifices, d', and has at the center of its closed end or crown a nipple, d, fitted to slide easily, Within which is a cylindrical tube, E, open at both ends, and Whose inner end carries an annular pad or tip, F, of india-rubber. The dimensions of the parts are such that when the tube E is pushed fully into the bottle, as shown at Fig. 1, the lips ofthe pad F become firmly seated against the inner surface ofthe end of the bottle, and thus forbid any communication to the interior of the bottle through said tube from the outer air.
A piston or collar, G, having rubber or other packing, H, which fits and hermetically closes the interior of the cylindrical'cap,is so secured to the tube E as, in the position of said tube shown in Fig. 1, to be located between the series of orices d' and the interior of the bottle, or, in other words, to be above said orifices, and in the' position shown in Fig. 2, to rest upon the closed end or crown of the cap, so as to be then wholly below said orifices.
In the normal condition of the apparatus (shown in Fig. l) the tube and its adjunots are retained in their elevated position by soldering to the nipple d the cup-formed capsule J. One or more minute Ventages, d", in the end of the cap D permit such escape of air as to facilitate the descent of the tube E on the melting of the solder, as aforesaid. l
Depressions a" a near the shoulder of the bottle may enable suspension mouth upward when desired.
The same bottle may be used as afire-extin- IOO guishing grenade by being tossed bodily into the re, or, the cap and its attachments being removed, the open bottle may be employed as a hand-sprinkler.
In order to secure efiicient Weight, so as to expedite descent of the liberated air-tube E, its collar G is preferably composed of lead.
I claim as new and of my invention- 1. In a re-extinguisher, the combination of bottle A, constructed for suspension in theinverted position, the cap D, having the series 0l' orifices elf, the nipple cl, and the ventage cZ, the gravitating tubular airinlet E, having the piston G, fitting within the cap, and the annular pad I1, adapted to press hermetically against the upper end of the bottle in the normal condition of the apparatus, and to be held to such condition by solder, in the manner and for the purpose explained.
2. In a fire-extinguisher, the combination of bottle A, constructed for suspension in the inverted position, the cylindrical cap D, having the series of orifices or ajutages d, the nipple d, and one or more ventages, cl, and the gravitating tubular air-inlet E, having the piston G, tting within said cap D, and having the annular pad F, adapted to press hermetically against the upperend of the bottle in the normal condition of the apparatus, and to beheld to such condition by capsule J, soldered to the nipple c, as and for the purpose set forth.
In testimony of which invention Iherennto set my hand.
JOHN A. VAGNER.
