Abstract

481,643. Displaying. RAWLINGSON, T. S. W. April 22, 1937, No. 11479. [Class 3 (i)] A device for teaching signalling &c. comprises a booklet of springy celluloid leaves 9 removably held by pins 10 in a block 8 pivoted about a spindle 7 carried by the sides 14 of a casing 1. A rod 18 slidable in a recess 19 in the bottom of the block 8 is pivoted by a yoke 17 to a nut 16 threaded on a shaft 11. The tips of the leaves 9 are held by the edge 6 of a rubber catch 5 mounted on the front wall of the casing 1. When the nut 16 is moved forward on rotation of a handle 15 geared to the shaft 11, the leaves 9 are flicked to display matter thereon in succession. The upper part 2 of the front wall is hinged to allow of the tip 6 being brought over all the leaves 9 when these are bent down, the nut 16 having been brought back to its original position to permit this to be done.
