A New Safety Belt. APART from the question of reliability, the one essential i'-'inirement in a safety belt is that it should have a quick- r< Ir.ise catch—a fitting which should really be quick-acting not only in name but in its function. Everything in an emer gency may depend on this quick-release catch, and several ingenious devices have been evolved and placed on the market from time to time, but many of them have failed to give thoroughly satisfactory service. One of the latest safety belts to be offered is that manufactured by the Aero Safety Belt Co., of this description. The firm's London office is at 235, Upper Thames Street, E.C. A Gledhill-Brook Telephone Mem. NOTE should be made of the fact that the telephone number of the London office of the Gledhill-Brook Time Re corders, Ltd., 26, Victoria Street, S.W., has just been changed. The call is now 1310 Victoria. For Stamping Test Marks. FOR marking metal parts which have passed their inspection tests, the old-fashioned punch is a very unsatis- * m m m m m The "Aero Safety Belt." $ -' of 108, City Road, London, E.C.. and of which details are given herewith. Here the quick-release catch fitted is not only extremely simple, but, as far as tests can show, is very reliable and efficient. It is only necessary to look at the accompanying illustrations to see that the method employed in the fashioning factory instrument, especially when round parts, such as rods, bolts, &c, have to be dealt with. Up-to-date works managers will, therefore, be interested in a little machine which is marketed by the Blackburn Aeroplane and Motor Co., Ltd., Olympia, Leeds—an indication that it is well adapted to the requirements of the aircraft industry. It is Sketch showing the principle of the quick release in the "Aero Safety Belt." of the catch is such that failure to open is next to impossible. The bar, it will be seen, is caught by the jaws, which are held dosed together by a cam action when the fly nut is turned at right angles to the slot. To release, it is only necessary to give the nut a quarter-turn so that it is parallel to the slot and tin- jaws of the clasp will immediately fly open and release the bar. Rivets and Eyelets. IT is pleasing to note the way in which many makers of accessories and components are realising the tremendous field which is offered them in connection with aircraft. In this connection attention may be drawn to the fact that the Hi furcated and Tubular Rivet Co., Ltd., of Aylesbury, Bucks, who have specialised in rivets, eyelets, staples, tacks, &c, are prepared to supply any of these items for use in aeroplane building. Makers should send for a copy of their list, which shows rivets, either copper or in other metals, in a great variety of shapes and sizes, either bifurcated or solid, while the range of thimbles and eyelets is no less extensive. At the same tune they are ready to quote for any fittings which may not appear in their catalogue, and to place their experience at the disposal of any firms who are in the market for goods The " Young " stamping machine. called the " Young " stamping machine, and by its aid it is possible to mark any metal, tube, pins, bolts, plate, turn- buckles, &c, many of which cannot be stamped with an ordinary punch. Not only is the machine capable of meeting all the demands made in the most varied of inspection depart ments, but as it only costs £5 5s., it should prove economical as a time-saver, apart from the satisfaction it should give in legible and clear markings.
