Abstract

805,083. Lens hoods for photographic cameras. ATKINSON, J. Jan. 10, 1957 [Jan.30, 1956], No. 2860/56. Class 98(1) A lens hood of rubber or similar material has a gapped or slotted adaptor ring of rigid material. As shown, hood 1 is clamped be- tween a metal adaptor ring 4a and threaded ring 10. In another form, the hood is formed with an internally serrated collar which is secured to a correspondingly serrated portion of the periphery of a gapped nylon or metal adaptor ring with an adhesive. The inner surface of the hood may be provided with three projections to retain a filter glass or, alternatively, it may have circular grooves to prevent reflection. According to the Provisional Specification, the adaptor ring can be designed to accommodate a filter.
