Having thus fully described the nature of my improvements in the illuminating vault-cover, what I claim therein is new, and desire to secure by Letters Patent, is--     The combining with the covering plate B B, a series of glasses of any suitable form, or of lenses, such as are shown at A A; said combination being effectively substantially in the manner described, by the aid of laminæ	of wood, or of soft metal, as shown at C C' and the glasses, or lenses, being defended from injury by knobs, or protuberances, as herein set forth. THADDEUS HYATT. Witnesses:     WM. B. AITKEN,     ALFRED B. KETCHAM.
