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.
