Claims

Claim lst In a chemical fire extinguisher, two rods extending from and rigidly secured to the main,plug of the.extindasher and connected together at this lower end by one or more, cross pieces provided with an angular, or pointed projection upon which the base of the acid bottle shall rest, in combination with an adjustable cap, arranged to fit over the top of the acid bottle and vertically adjusted by a screw passing through the main plug. 2nd. In a chemical fire extinguisher In which the body of the acid bottle is inciroled by a ring horizontally pivoted between the two rods extending from, and rigidly secured to the main plug of the extinguisher, which rods are connected together at the base by a cross piece having a pointed projection arranged to come in contact with the bottom of the acid bottle, in combination with a fracturing device, operated from the exterior of the extinguisher and arranged to compress the bottle against the pointed projection, for the purpose of breaking the lower portion of the bottle. 3rd. In a chemical fire extinguisher in which the acid bottle is supported between two rods extending from and rigidly secured to the main plug of the extinguisher, a cross head working upon guides, forming part of, or attached to the rods, the said cross head being vertically adjusted by a screw passing through the main plug in combination with a cap arranged to fit over the top of the bottle and upon a neck extending from the cross head, the said cap being arranged so that it may be adjusted to permit the insertion of the bottle or secured to the cross head so that its downward movement shall cause the cap to compress the bottle, thereby producing the desired fracture. 4th. In a chemical fire extinguisher in which the bottom of the acid bottle rests upon a pointed projection, the combination of a cap fitting over the neck of the bottle and provided with a washer of rubber, leather or other soft material, to prevent direct contact between the cap and.the bottle, the said cap being provided with adjusting mechanism for the purpose of compressing the bottle between the cap and pointed projection and thus causing the bottle to fracture at its bottom. 5th. In a chemical fire extinguisher in which the acid rests upon a stationary pointed projection, an adjustable cross head with a downwardly projecting neck having a feather key formed upon one side of it, in combination with a cap arranged to fit over the top of the bottle and unto the projecting neck. a slotted passage way being made in the cap to admit the feather key, and.a spring arranged to hold the cap in its proper relative position,
