the inner side thereof, said leg having a front flat face perpendicular or nearly so to the plane of the body portion which extends between two opposite side angles of the body portion with its center at a distance from the intermediate front angle of said body portion, the side surfaces of said leg being parallel with each other and in the same plane with the sides of the body portion while the rear to surface of said leg is formed of a plurality of oblique facets which reach to the rear margins of said body portion, said body portion being provided between said front face of the leg and said front angle of the body portion with a flat surface parallel with the outer face of said body portion whereby rays of light may pass perpendicularly through the latter in front of the leg into the inclosed space to be illuminated.     2. An illuminating-lens comprising a body portion and a leg projecting from the inner side thereof, said leg having a flat front face perpendicular or nearly so to the plane of the body portion and, at its rear side, a central and two lateral, triangular facets, the central rear facet being arranged to extend across the leg the full width thereof and to intersect the front, flat face of said leg, at its outer extremity with its side margins converging upwardly and meeting midway between the side faces of the leg and the lateral triangular facets being arranged to intersect the central, triangular facet with its side margins converging

toward and meeting at points at the side edges of the leg at the extremity of the same.     3. An illuminating-lens comprising a body portion and a leg projecting from the inner side thereof, said leg having a flat, front face perpendicular or nearly so to the plane of the body portion, two parallel, flat side faces, also perpendicular to the plane of the body portion and at its rear side, a central and two lateral, oblique, triangular facets; the side faces of the leg being of triangular form with their side margins converging to a point at the outer extremity of the leg, the central rear facet being arranged to extend across the leg the full width thereof and to intersect the front flat face of said leg at its outer extremity with its side margins converging upwardly and meeting midway between the side faces of the leg, and the lateral triangular facets extending between and intersecting the flat, triangular side faces of the leg and the said central triangular facet on lines which converge toward and meet at the extremity of the leg at the side edges of the same.     In testimony that I claim the foregoing as my invention I affix my signature, in presence of two witnesses, this 31st day of March, A. D. 1897. EUGENE J. SULLIVAN. Witnesses:     C. CLARENCE POOLE,     CHARLES G. MASON.
