Abstract
Abstract Apparatus for determining flammability of fabrics or other materials. The apparatus comprises a baseplate, means fixed to the baseplate for positioning and supporting a plurality of specimens above the baseplate in a spaced relationship such as to provide a gap between the specimens extending transversely of the baseplate and means for holding specimen igniting means on the baseplate beneath the specimens and in alignment with the transverse gap.

Claim 1
Independent Claim
66 words
Apparatus for determining flammability comprising a baseplate, means fixed to the baseplate for positioning and supporting a plurality of specimens above said baseplate in a spaced relationship such as to provide a gap between said specimens extending transversely of said baseplate and means for holding specimen igniting means on the baseplate beneath said specimens and in alignment with said transverse gap substantially midway between the specimens.
Claim 2
Dependent Claim
66 words
Apparatus for determining flammability comprising a baseplate, means fixed to the baseplate for positioning and supporting a plurality of specimens above said baseplate in a spaced relationship such as to provide a gap between said specimens extending transversely of said baseplate and means for holding specimen igniting means on the baseplate beneath said specimens and in alignment with said transverse gap substantially midway between the specimens.
Claim 3
Dependent Claim
105 words
Apparatus comprising a baseplate, specimen positioning means on the baseplate and located near thE periphery thereof, further specimen positioning means located transversely across the baseplate near the center thereof, spaced specimen supporting means on the baseplate of shorter height than the specimen positioning means, whereby a pair of specimens may be supported on said supporting means while being held in position by said positioning means with a transverse gap between said specimens defined by the further specimen positioning means which extend transversely across the baseplate, and means for holding specimen igniting means on the baseplate beneath said specimens and in alignment with said transverse gap.
Claim 4
Dependent Claim
105 words
Apparatus comprising a baseplate, specimen positioning means on the baseplate and located near thE periphery thereof, further specimen positioning means located transversely across the baseplate near the center thereof, spaced specimen supporting means on the baseplate of shorter height than the specimen positioning means, whereby a pair of specimens may be supported on said supporting means while being held in position by said positioning means with a transverse gap between said specimens defined by the further specimen positioning means which extend transversely across the baseplate, and means for holding specimen igniting means on the baseplate beneath said specimens and in alignment with said transverse gap.
Claim 5
Dependent Claim
19 words
