A movable connection between the joints 17 :nul "2l is provided in the form oi i linlc QG, pivotcd about the shalt 13, und having one end secured to the joint 2l, while the other cnil, indicated et 27, is pivotnlly sccured to :in arm Q8, the front portion ot' which is movnbly mounted in the front joint 18 of the finger.

The thumb of the ertiicinl hand ie shown as' consisting' olf the tivo jointe 3l und the fore joint being' pivoted. on e pin (32, which extendf; through the rigid member 3l. into the plate ll. The joint 33 ol the thnmh also is connected h v means of the linlcr with n bifurcutetl lever sliihible in the loiver surface ot the wrist plete ll.

The strap 5, being attached at (34 (Figi: Gl to the front portion of the yoke e Slight forvurd movement ot the arm neceSSni-ily will release the tension under which the strap 5 may be. This movement will, how ever, tension the Strap 6, which is attac-heel tothe rear ortion of the yoke at 65 (Fig. 8)

The pullD o the tension member ll will cause the shaft and the slide 16 connected therewith to move rearwardly on the plete A s the holt 39 of the Slide i6 is connected hy the link l5 with the Vstationznfv plate 14, it is obvious that the angle of this link 15 with respect to the stationeryplute 14- Will be changed, ami this link 'l5 therefore will swing the plete 13. and hence oleo the pletel 7 about the pertaining pivot lll The yparte may then assume the position shown in Fig. l.

` he movement of the slide 16 in direction toward the. plate 7 naturally will also move the arms 24 rearwardly, thus causing the middle jointe 17 of the lingers to'es'sume the bent position in which they are shown (Fig. l). Inrthis movement the midollo joints 17 will Wing about the Shafts 13, with which they are connected by the arms 26.
