Abstract
1393387 Educational toy EPOCH CO Ltd 15 June 1972 [22 Nov 1971] 28009/72 Heading A6H [Also in Divisions G3 and G5] An educational device comprises a number of differently-shaped blocks 16 which can be inserted through corresponding holes 14 in a housing and means for uncovering the holes and then subsequently closing any unmatched holes after a predetermined time. The timing means consists of a spring 42 wound by a knob 46. When the knob is released, the spring rotates a series of gears, one of which engages a blade 48 to make a noise simulating a ticking clock, the "time" being indicated by marks on the knob. Each hole 14 is covered by a gate 59, Fig. 3. Each gate carries a pin (62) confined within a slot 54 and engaged by a spring 64, biassing the gate about a pivot 56 on a disc 50. During the last part of the rotation of the knob 46 in the spring-winding direction, an abutment on its lower surface carries round the disc 50 to open the gates.
