UNITED STATES PATENT OFFICE.

DESIGN FOR A LENS FOR VAULT-LIGHTS.

SPECIFICATION forming part of Design No. 22,391, dated May 2, 1893.

Application filed Marcl131. 1393i Serial No, 408.574 Term ofpatent 14 year To all ZtltO/Ib it may concern.

tie it known that l, JAtI'UH JAto'ns, a citizen of the l'nited States, residing at New York city, in the county of New York, and in the State of New York, have invented a certain new and useful Design for a Lens for Vault- Lights, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying d rawings, in which Figure 1 shows a plan view of a lens or glass formed in accordance with my design, and Fig. i, a View of a cross-seetion of the same on line .7), a, of Fig. 1.

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

The object of my invention has been to prorule a new, useful, and original design for a lens or glass for vault lights and illuminating tiles,and, to this end my invention consists, in the design substantially as hereinafter specitied and shown in the drawings.

The part of the lens or glass for which my design is especially intended is that one, the outer side of which will be exposed to view in the finished vault light or illuminatingtile.

In the drawings, A designates the body of the lens or glass, and A the portion, which is intended to appear to the view in the finished lighter-tile. Ingcneraloutlinesuchpartisrcctangular. Along its four sides are series of V shaped notches a, which are set close together, so as to leave between them V-shapetl outwardly projecting portions a. The bottom of these notches n,aro substantiallystraightlines extending downward and outward and situated in planes at rightangles to the respective sides of the top. The outline of the extreme outer portion of part A shows the corners of the rectangle cut oil, at right angles to diagoual lines to such rectangle. llcyond such oints said corners are beveled in opposite directions downward and outward from the respective diagonals; but the specified formation of the corners of the lens, does not form an essential feature of my design. it can be varied, desired, without departure from my invention. The notehing of the outer portion or top of the lens, in the manner, described, produces, along the foursidesofsuch part, a series of oppositely inclined facets. There is, at a short distance outside of the part A, made in accordance with my design, a raised rib tt' running around the lens body parallel to the sides thereof. When a lens, made in accordance with my design,as here inbetore described and shown in the drawings, having the series of oppositely inclined facets along its four sides, and the edge of its top surface made on a wave line, is embedded in the cement, or other holding material ordinarily used in an illuminating tile, or vault light, so that the said portion A shows above said holding material, the tinished vault light or illuminating tile will, because of the form of part A, be given a very pleasing and attractive appearance.

Having thus described my invention, what I claim is- The design for alens orglass for vaultlights and illuminating tiles, substantially as herein shown and described.

In testimony that I claim the foregoingl have hereunto set my hand this 20th day of February, A. I 18013.
