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