US 3,999,860 A · Apparatus for textile color analysis

Abstract

In a textile color analyzer, a sample of textile is supported on the pad of an elevator mechanism that holds the sample against an instrument head. The head has an opaque housing provided with a chamber having an opening therein. A glass plate is mounted in the head and covers the opening and presses against the textile sample to provide a stable reference plane. The head includes an illuminating fiber optic bundle that directs light substantially perpendicular to the textile sample. A plurality of additional fiber optic bundles are mounted to receive diffuse light reflected from the sample. The elevator includes a pad of translucent polyethelene material that backs up the textile sample and takes on the color of the sample so that there are no adverse effects due to light showing through the sample and reflecting from the plate.

Dependent claims

In apparatus for measuring the color of a test sample, the combination comprising:

a head assembly comprising:
an opaque housing having an opening therein communicating with a chamber therein,
a transparent plate connected to said housing and extending across said opening,
first means connected to said housing and communicating with said chamber for illuminating said test sample,
and second means connected to said housing and communicating with said chamber for collecting light reflected from said test sample;
a support pad of polyethylene, adjacent to said plate;
and means mounting said head assembly and said pad for relative movement between first and second positions;
said pad and said head assembly being spaced when in said first position to allow said test sample to be placed between said plate and said pad, said pad and said head assembly being operative to press said test sample therebetween when in said second position whereby said test sample is illuminated by light from said first means while light reflected from said test sample is collected by said second means.
