To 7 this, effect, the device comprises a framework constituting the forearm and having secured theretothe tool holder the said framework being pivoted to a forked member carrying aleather band whereby the artificial arm is secured to the stump.
The articulation is disposed. in such manner as tovary' the angular position of the parts thereof as .desired or to bring the same into alignment while thefdevic-e connectingthe' arm with the' forea-rm' provides for the rotation of the latter in such manner as to plaee'the. tool in any'desired position; The various parts are held in place by look ing devices which can be instantly engaged or released. by a simple pre'ssureupon the vices.
