(Patented) |
"SUNBURST"
PRISMS. |
| "Schwickart's Sunburst" Prisms
(patented in the United States, Canada, Great Britain and Germany)
are ornamental, have a higher artistic appearance than any other
construction, and solve the problem of a really efficient sidewalk,
vault or ceiling light. |
| ADVANTAGES. |
| This prismatic system does not
tire the eyes like artificial lights, and the cost of maintenance
is practically nothing. The economy of the "Sunburst" Prism
System, which we claim to be the best, is due to the superior
efficiency of the prisms.
The vertical and quadrilateral
diffusion of light is absolutely obtained with these prisms without
the aid of crude or ugly devices. Each lens takes care of its
own expansion and contraction, and if any prisms or settings
should become injured, repairs can easily be made at a minimum
of trouble and expense.
The lenses have great strength and
beauty, and when used as a skylight the white cement obviates
the black spots so noticeable in other systems.
In the use of the "Sunburst" Vault
Light the necessity of transparent doors is eliminated, insuring
an additional saving in the cost of the doors.
One third of the space required by
other systems is sufficient for "Sunburst" Prisms to transmit
the same amount of light, and all remaining space around the
vault-light panel can be made of reinforced cement. |

TION. |
| The lenses have a plain top
surface, set flush in cement, making a water and moisture proof
building light. The square bottom portions of the lenses have
the sides projecting below the cross-bars which are spaced so
that the square bases of the adjacent lenses abut both in a
transverse and longitudinal direction, forming an under surface
of glass of an unbroken continuity.
The conical bottom portion of each
lens has an angular bead which anchors it firmly in position,
and the prisms in the lower part of the lens tend to refract

"SUNBURST"
WINDOW
REFLECTOR. |
| Our new "Sunburst" Prism Reflector
Attachment is designed to illuminate dark and dismal offices and
apartments, rooms in lower floors of high buildings, rooms lighted
by shaft or court, and wherever direct side light can not be
obtained.
The Reflector is very ornamental and is
attached to the outside face of the wall at top of the window. it
is made to fit any size window opening.
The Reflector is made slightly wider
than the window, an inch or more on each side of the opening, to
allow for fastening to the wall.
The top surface is made of "Sunburst"
Prisms 12 inches wide and projecting at right angles to the face of
the building. The light direct from above passes through and is
then, by the aid of the mirror attachment, received as reflection
from the prisms and distributed both vertically and laterally, and
penetrates into the room a distance of 40 feet, with the regulation
12-inch top surface of "Sunburst" Prisms, containing four rows of
lenses. If the depth of the room exceeds 40 feet an additional row
of lenses on the top surface is required, which will cause the
reflected light to penetrate 10 feet farther. |

LIGHT
REFLECTOR. |
| The "Sunburst" Prism Vault Light with
Reflector attachment is especially valuable for the purpose of lighting
basement rooms or cellars. The transmission and diffusion of the light
through our prismatic lenses is uniformly and equally effected in all
directions. This fact in itself has made our "Sunburst" Reflector
possible, and the same result could not be obtained from any other
prism lacking this all important quality.
