frIWO new items of equipment of
j_ interest to coachbuilders and passenger-vehicle operators have been introduced by Quicktho (1928), Ltd., Point Pleasant, Wandsworth, London, S.W.I8. One consists of a mechanism for altering the angle of inclination of a seat, whilst the other is a neat continuous louvre, which enables the glass panels rapidly to be fitted or replaced and gives an unbroken body line along the tops of the windows. Dealing first with the seat equipment, a system of links connects the seat base, the board and the back on each side. The operation of a handle protruding from the front of the seat, at a convenient level. imparts, through the medium of suitable gears, the movement to the links that alters the angle of inclination of the seat hoard and back. The correct angle between these two components is thus preserved.
The mechanism is neat in design and may easily be operated ; its price is about £1 15s.
The louvre is made up of a Op rail extending for the full length of the vehicle. At tached to it are the end and intermediate drop channels with the cover plates, whilst bevelled distance pieces determine the angle between the body and the Louvre. The glass is inserted between the channels, and a small piece of rub ber and a metal capping are placed in position at the bottom of the glass, a screw being passed through them and the cover plate.
In this way, the glass is securely held in position, and the small rubber inserts referred to and two or three in the top rail prevent vibration from being transmitted to the glazing. The prices of the louvre vary from 5s, 3d. to 7s. fid, per section, according to the size, shape and finish.
An accompanying sketch explains how the parts are assembled end the system of securing the glass, a rubber pad, together with its metal capping and retaining screw, being shown detached.
MI OR use in conjunction with the
Beelawat ball-race runner for sliding doors and opening heads, Beckett, Laycock and Watkinson, Ltd., Acton Lane, London, N.W.10, has introduced a new type of spring-loaded fitting.
The top fitting consists Of a channel containing a sliding bail-bearing cage, whilst another channel carrying the door plates works inside the cage, the outside channel being attached to the main bodywork. The gear gives smooth working, and an additional advantage is its lightness, a considerable reduction. in weight having been effected.
At the foot of the door the rollers • working on the floor channel are springmounted, each roller being carried in the
fork of a vertical tube. The lastnamed component contains the spring and works inside a bracket attached to the door. In this way due allowance. is made for temporary distortion.
Various types of top and bottom bracket are available, so that all requirements should adequately be met.
It is interesting to note that Beckett, Laycock and Watkinson, Ltd., is.supplys ing sliding windows, 4 ft. S ins. long and Ili ins, deep, for the Percival Gull type of aircraft. The window weighs only 131 lb. complete.
