Clever Design in New Sliding Window

ALREADY wen known and of established reputation, the Beclawat Typhoon half-drop window has now been improved still further. In its new form it is known as the Typhoon Major.
The most striking part of the modification is the incorporation of new floating side channels, fashioned from stainless steel, and thus dealing effectively with the corrosion problem. It must be understood that the use of such intermediary channels makes for much easier operation and the elimination of jamming or jerky action.
In the new Typhoon window these floating channels are sprung at the sides, so that sufficient free movement is given to allow for any flexing of the body structure. Replaceable cottontape webbing strips are fitted on the rising sash, to avoid a metal-to-metal sliding contact when the window is being operated. Location of the sliding half at any position is brought about by• means of a series of phosphor-bronze wedges, spring-loaded and operated automatically by a cam on each end of the spindle which bears the windoivoperating handle.
The guard rail and top section of the rising sash have been redesigned to deal with the tendency for wider windows and with vibration. The window is protected against the entry of draught and rain both at the top and at the guard-rail position. As the line of the top section is unbroken, a good seal is obtained against the specially moulded sponge rubber.
An interesting point is the facility of pushing up the sliding half from outside, which is a considerable advantage in washing down.
The manufacturer is Beckett, Laycock and Watkinson, Ltd., Acton Lane, London, N .W.10 .
