REINFORCED CONCRETE VAULT LIGHTS, with Unbreakable Glazed Porcelain Cups; CURB GUARDS.

Advantages of Reinforced Concrete Vault Lights.
GLAZED PORCELAIN CUPS—Reinforced concrete vault lights are so well known that they need no comment—but unbreakable porcelain cups are a new invention and a great improvement over the ordinary reinforced concrete vault lights. The glazed porcelain cups increase the volume of light by reason of the light which is refracted from their glazed surfaces; they can be readily cleaned, whereas the ordinary concrete vault lights can not be cleaned on their undersurface and soon become so dirty and grimed with dust and dirt as to have no light refractory value.
The appearance of the undersurface or soffit of these unbreakable glazed porcelain cups is very ornate and beautiful and makes an ideal ceiling for salesrooms, barber shops, restaurants or other rooms where a decorative effect is desired; and, at the same time, they serve a practical purpose in thoroughly illuminating the room with light rays akin to natural daylight.
The porcelain cups are practically indestructible and their design is such that it is impossible to dislodge them from the concrete structure without destroying the whole vault light. The glazing of the porcelain cups prevents permanent discoloration or staining, as they can be readily cleaned with a damp cloth or wet brush.
GLASS—The glass used in this construction is the very best obtainable for vault lights and is made especially for the purpose intended. Every lens is protected by a coating of expansive material around its upper outside edge and is so designed that in case of break or fracture it can be readily replaced without destroying or shipping the surrounding concrete.
