IMPROVEMENT IN ILLUMINATING VAULT-COVERS.
Specification forming part of Letters Patent No. 140,709, dated July'S, 1873; application iiled December 23, 1870.
To all lwhom it may sondern:
Be it known that I, THADDEUS HYATT, of New York city, county, and State, formerly of Atchison, Kansas, have invented certain new and useful Improvements in Plates for Sidewalks 5 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying'drawings making a part of this specication, in which- Figure l is a plan view of the upper side of a section of a plate containin g my improvements. Fig. 2 is a cross-section of the same. Fig. 3 is a longitudinal section upon a line eX- tending through the center of one of the ridges; and Figs. 4, 5, and 6 are like views of a plate provided with larger glasses, which have a square form.
Letters of like name and kind refer to like parts in each of the iigures.
The design of my invention is to furnish an illuminated coverin g for areas, coal-vaults, Svc., in which the glass lenses shall be protected in a great degree from abrasion by dust upon the feet of persons walking over the same; and it consists in a corrugated illuminating pavementplate in which the lenses are placed wholly or in part within the sides of the ridges, substantially as and for the purpose hereinafter specias to preserve the uniformity of the same, and, as nearly the whole of said lens is below the highest portion of the ridge in which it is inserted, it will be seen that but a small portion of its upper surface is exposed to contact with the feet of persons passing over the plate, and consequently only such exposed portion can become abraded so as to diminish the lighttransmitting qualities of the glass.
In Figs. 4, 5, and 6 is shown a modification of my invention, in which the lenses are Vincreased in relative dimensions, so as to cause each to form a part of two or more ridges and furrows. When applied in this manner the light-transmitting capacity of the pavement is materially increased, while-as great a proportion of the surface of each lens is protected from abrasive action.
Dust and water falling into the furrows will usually pass away without attention, but, if necessary, can easilybe removed with a broom, so as to leave those portions of the lens which` are below the upper side of the ridges unobstruct-ed.
The pavement-plate thus constructed poshave hereunto set my hand this 18th day of November, 1870. 1
