Abstract
535,831. Luminescent materials. SCHECHTER, P. Oct. 25, 1939, No. 28647. [Class 39 (i)] [Also in Group XXV] A lock and key are provided with luminous marks, which, or some of which, act as guides in introducing the key into the lock. Tne Figures show a key and lock furnished with such marks 114. One of the marks is formed in the shoulder face 112 of the key, and is only visible when the key is the right way up for inserting into the lock. A mark A may be formed on the elements facing the key-tip (Fig. 5) and a similar mark may be formed on the lock (Fig. 6), so that when the marks are together the key is in proper position for insertion. A further similar mark on the key shown in Fig. 2 indicates when the key has been pushed home. There may also be a mark round the rim of the guard plate 13. Fig. 11 shows a mark on a sheet of material 1141 engaging the sides 117 of a slot in the key handle.
