Creeping Baby Doll Patent Model (right side)

This model demonstrates the invention of a mechanical crawling doll. It accompanied the patent submission of George Pemberton Clarke, who received U.S. patent No. 118,435 on 29 August 1871 for his “Natural Creeping Baby Doll.” The original patent office tag is still attached with red tape. Clarke’s patent was an improvement on the crawling baby doll patent of his associate Robert J. Clay (No. 112,550 granted 14 March 1871).

The doll’s head, two arms and two legs are made of painted plaster. The arms and legs are hinged to a brass clockwork body that actuates the arms and legs in imitation of crawling, but the doll moves forward by rolling along on two toothed wheels. A flat piece of wood is attached to top of the movement.
