Abstract: An artificial hand has a stationary wrist and two fingers and a thumb pivotal from a horizontal axis in the wrist. The thumb may have two separable portions, one of which is pivotal away from the other along a generally vertical axis by manual prepositioning. This enables rounded objects such as doorknobs to be grasped by the curved main finger and the two thumb portions, making stable three-point contact. The two fingers are pivotal along the wrist axis in a fixed range of motion with respect to the thumb, and a spring urges the fingers toward a normal open position. Tension of a sheathed cable fitted to a standard body harness closes the fingers to the thumb, enabling a powerful grip. The second finger is straight and normally remains alongside the curved finger until, upon closure of the curved finger and contact to its tip with the thumb, further cable tension closes the straight finger against the thumb to grip small or flat, thin objects.
