Abstract

25,036. Adams, A. L. Nov. 3. Lens fittings.-A lens hood, more particularly for use with folding cameras, is adapted to extend itself automatically when released, and is capable of being readily folded or closed into small space. In the form shown in Fig. 4, two end rings a, care connected by flexible material b, such as silk, leather, rubber, &c., which is adapted to be extended by a spring x. In a modification, the hood is formed of a coiled spring strip adapted to extend itself axially, the edges of the coils overlapping so as to exclude light.
