GENERAL
REMARKS
- Hayward's Patent "Pludelux" Prism Lights
(page 7, Section P) are used where the very best results
are required, as the prisms in every pocket produce a solid reflecting
surface from the whole area of the underside of the Pavement Light to back
of basement.
- Hayward's Patent "Semi-Prism" Lights
(page 7, Section B) are used where the daylight is required
to be thrown to the back of basement—at the same time with good
overhead and best distributed light.
- Hayward's Convex Lens Lights
(page 7, Section C) are used where best overhead and
diffused light is required.
- Hayward's Convex Rough Plate Lights
(page 8, Section D) are used where good overhead light
is required with neatness and economy.
- Hayward's Floor Lights
(page 8) are used where good overhead light is required
with ornamental appearance.
- In taking out quantities, allow 2 inches
extra in length and depth for each flange (see page 9)
resting on curbs, or to break joint with stallboard beyond the "sight size;"
also be careful to allow sufficient depth beyond the Fascia line into reveals
of pilasters, windows, doors, &c. Light should be measured as square when
stopped out.
- The Light should be made good to curbs in
Portland cement.
- The Lights will carry themselves 6 or 7 feet in
length without support along the back; it is preferable to support them
generally on three sides (front and each end), and avoid fixing a
longitudinal girder along the back, which impedes the light very
considerably.
- If the Lights are larger than 6 ft. 2 ins.
× 3 ft. 10¼ ins. out, or 7 ft. 4 ins. × 2 ft. 8¼
ins. out, and have to be in two parts, they can have a grooved butt joint,
or two flanges can come together (see pages 9 and
10); and in either case a light
T or
H iron can be fixed under
joint transversely from front curb to flooring, so as to avoid a
longitudinal back girder (see page 9).
- Lights to open cost from 6/ to 12/ per foot
super. extra to price of fixed Lights (see pages 11,
31, 32).
- Rolling Lights require good protection for
openings in pavement, and it is found a convenient plan to open the
stallboard windows or iron grills outwards, securing each at foot with
a bolt dropping into stone curb or pavement (see page 33).
- Hayward's Lights are glazed ready
for the builders to fix.
- Architects are advised not to use wrought-iron
frames, which corrode and rust much more rapidly than cast iron; also
wrought-iron springs when a comparatively small weight comes on it, and
the glass is bound to crack across, whereas Hayward's Frames are
rigid.
TO
ARCHITECTS, ENGINEERS, AND
OWNERS OF PROPERTY
In order to ensure the best result
and increase in letting value of Business Property, it is of the utmost
importance that HAYWARD'S PATENT
"SEMI-PRISM" LIGHTS should be clearly and
distinctly specified, otherwise inferior imitations might be employed,
which will cause disappointment.
A visit to H. B. & E.'s Large
New Premises, Union Street, where Hayward's Lights are fixed to light
the basement and five floors, under varying conditions, would ensure
practical results and with economy.
