IMPROVEMENT IN IL LUMINATING VAULT-COVERS.

Specification forming part of Letters Patent No. 145,260, dated Dec( mker 2,1873; applieaiion filed October 22, 1873.

CAsE 7.

To all whom it may concern Beit known that I, THADDEUs HYATT, of New York, in the county of New York, and in the State of N ew York, have invented certain new and useful Improvements in Illuminating- Gratings; 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 specification, in which- Figure l is a perspective view of a lens set in a metal frame provided with a head and screw-shank, and the nut employed for securing the same in place. Figs. 2 and 3 are like views of said lens, showing modifications in the construction of the fastening devices. Fig. 4L is a plan view of a pavement-plate having saidlenses set within itsilluminating-openings and Fig. 5 is a vertical section of the same.

Letters of like naine and kind refer to like parts in each of the figures.

The design of my invention is to more thoroughly protect from injury glass lenses which are made detachable from their supportingplate; and it consists in a glass lens having molded upon its periphery a metal frame which is provided with a projecting' head or iiange, and with a threaded shankor its equivalent, substantially as a-nd for the purpose hereinafter speciiied.

In the annexed drawings, A represents a glass illuminating-lens, having, preferably, the form shown in Fig. 5, upon and around the sides of which is c-ast a soft-metal fra1ne,B, which frame has at its upper end a projecting head or iiange, b, and below the same is provided with a screw-thread, b.4 As thus inclosed the lens and its frame are placed within the light-opening c of a metal plate, C, with the head b resting upon the upper side of said plate, after which a nut, I), is placed over the threaded shank b and screwed upward against said plate, locking said parts in pla-ce.

If desired, the screw-thread maybe omitted from the shank b', and three or more radiallyprojecting lugs, b, provided upon the saine, which lugs, when passed through corresponding notches c in the sides of the opening c, may be turned with the frame B and caused to pass over inclines provided upon the under side of said plate.

3y omitting the inclines from the lower side of the plate C and providing a suflicient space between the latter and the upper end ot' the lugs a nut, D', provided with notches l and inclines d', may be passed over the shank and turned until said inclines, operating as wedges, draw the frame B iirinly down upon said plate.A

Both of the latter forms of attachment,I however, are considered as modifications of the fastening iirst described.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- An illuminating-lens having molded upon its periphery a metal frame which is provided with a projecting head or ange, and with a threaded shank, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of July, 1873.

THADDEUS HYATT.
