HAVING concluded, from thorough investigations, that the only satisfactory way of blacking out coaches and buses, without detracting from passengers' comfort, is to employ blinds, Wilmot-Breeden, Ltd., Camden Street, Birmingham, 1, has introduced a fitment of this description named the Centre Zipp blind. When closed, it completely obscures the internal lighting, and when open affords 50 per cent, of the normal daylight illumination. Only near the saloon entrances, it is claimed, need dim lamps be used.
The blinds are fitted by removing the fillets Or cappings from the tops and sides of the windows, placing the blinds in position and refixing the fillets. If this method be not practicable, a metal frame is provided for each blind. No difficulty is presented by half-drop windows having winding handles.
Permanently secured, as outlined, along the top and sides, the blind is held open and closed, respectively, by an upper and lower pair of press-studs, a zipp fastener joining the edges at the centre, This incorporates a lock, which can be released only with a special key. Thus, passengers cannot open the blind.
