Other similar toys worked by wheels can be made by cutting a hole in the bottom of the cart. One axle of the cart must run exactly under this hole, it must be made of wire and bent as B C in Fig. 460.
Fig. 459
D and E are pieces of tin nailed to the cart, through holes in which axle B C freely turns; or wooden blocks may be nailed on for the axle to turn in, if tin cannot be obtained. The ends of the axle are securely fastened into solid wooden wheels. As the wheels revolve they will push up and down a piece of wire or wooden rod, F, which is fastened to the bent part of the axle. Now F can be used to work a number of simple toys, if its free end is fastened to the part which it is desired to move. For example by this means an animal's mouth may be made to open and shut as it is wheeled along, or its head to wag; a blacksmith may be made to strike his anvil, the drummer to beat his drum. The ingenious child will be able to adapt this simple piece of mechanism to many a toy.
