Abstract
Abstract In a machine for performing work characterized by a manipulator arm having a working hand rotatably carried in a frame rotatably mounted in a support and gear train means for rotating the hand, the frame and the support to permit bending and swivelling motions of the hand. A transmission gearing arrangement is provided between the frame rotating means and the hand rotating means to prevent rotating the hand through rotating the frame, and another transmission gearing arrangement connects the support rotating means and the frame rotating means for preventing rotating the frame and the hand through rotating the support, whereby undesirable bending and swivelling of the hand are eliminated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A machine for performing work comprising: a base member; an arm member retractably mounted on and extending from said base member; first supporting means for a vorking hand rotatably mounted on a free end of said arm member in a first plane substantially perpendicular to the longitudinally extending arm member; second supporting means rotatably mounted on said first supporting means for rotatation in a second plane perpendicular to said first plane for producing a bending action with said hand; hand means mounted on said second supporting means rotatable in a third plane parallel to the rotating axis of said second supporting means and having a finger arrangement thereon capable of performing a gripping operation; means for rotating said first supporting means; first gearing means for rotating said second supporting means; second gearing means for rotating said hand means; and a transmission means connecting said first and second gearing means to prevent undesirable rotating motion of said hand means when said first supporting means is being rotated.
Claim 2
Dependent Claim
166 words
A machine for performing work comprising: a base member; an arm member retractably mounted on and extending from said base member; first supporting means for a vorking hand rotatably mounted on a free end of said arm member in a first plane substantially perpendicular to the longitudinally extending arm member; second supporting means rotatably mounted on said first supporting means for rotatation in a second plane perpendicular to said first plane for producing a bending action with said hand; hand means mounted on said second supporting means rotatable in a third plane parallel to the rotating axis of said second supporting means and having a finger arrangement thereon capable of performing a gripping operation; means for rotating said first supporting means; first gearing means for rotating said second supporting means; second gearing means for rotating said hand means; and a transmission means connecting said first and second gearing means to prevent undesirable rotating motion of said hand means when said first supporting means is being rotated.
Claim 3
Dependent Claim
52 words
A machine for performing work according to claim 1, further comprising: another transmission means connecting said means for rotating the first support means and first gearing means to prevent undesirable rotating motion of said second supporting means and said hand means when the hand is being rotated by the second gearing means.
Claim 4
Dependent Claim
118 words
A machine for performing work according to claim 1, further comprising: a first rotary actuator; the means for rotating the first supporting means consisting of a first drive shaft connecting said first rotary actuator and said first supporting means; a second rotary actuator; a second drive shaft connecting said second rotary actuator and said first gearing means; a third actuator; a third drive shaft connecting said third actuator and said second gearing means; and said means for rotating the first supporting means connecting said first drive shaft and said first gearing means through said second rotary actuator to prevent undesirable rotary motion of said second supporting means and said hand means during rotation of the first supporting means.
Claim 5
Dependent Claim
156 words
A machine for performing work comprising: a base member; an arm member retractably mounted on and extending from said base member; first supporting means for a working hand rotatably mounted on a free end of said arm member in a first plane substantially perpendicular to the longitudinally extending arm member; second supporting means rotatably mounted on said first supporting means for rotation in a second plane perpendicular to said first plane for producing a bending action with said hand; hand means mounted on said second supporting means rotatable in a third plane parallel to the rotating axis of said second supporting means and having a finger arrangement thereon capable of performing a gripping operation; means for rotating said first supporting means; first gearing means for rotating said second supporting means; second gearing means for rotating said hand means; and wherein said first supporting means is a substantially cylindrical-shaped casing housing said first and second gearing means.
Claim 6
Dependent Claim
156 words
A machine for performing work comprising: a base member; an arm member retractably mounted on and extending from said base member; first supporting means for a working hand rotatably mounted on a free end of said arm member in a first plane substantially perpendicular to the longitudinally extending arm member; second supporting means rotatably mounted on said first supporting means for rotation in a second plane perpendicular to said first plane for producing a bending action with said hand; hand means mounted on said second supporting means rotatable in a third plane parallel to the rotating axis of said second supporting means and having a finger arrangement thereon capable of performing a gripping operation; means for rotating said first supporting means; first gearing means for rotating said second supporting means; second gearing means for rotating said hand means; and wherein said first supporting means is a substantially cylindrical-shaped casing housing said first and second gearing means.
Claim 7
Dependent Claim
193 words
A machine for performing work comprising: a base member; an arm member extending from said base member; first support means mounted on one end of said arm member and rotatable about a given axis; second support means rotatably mounted on said first support means for rotation in a plane parallel to said given axis; a mechanical hand mounted on said second support means for rotation about an axis aligned with said given axis; means for rotating said first support means; first gearing means for rotating said second support means; second gearing means for rotating said mechanical hand; first transmission means connecting said first gearing means and said second gearing means for operating the same in unison to prevent said mechanical hand being undesirably rotated through said second gearing means when operating said gearing means for rotating said second support means only; and, second transmission means connecting said means for rotating said first support means and said first transmission means for preventing said second support means and said mechanical hand being undesirably rotated through said first gearing means and said second gearing means when operating said means for rotating said first support means only.
Claim 8
Dependent Claim
193 words
A machine for performing work comprising: a base member; an arm member extending from said base member; first support means mounted on one end of said arm member and rotatable about a given axis; second support means rotatably mounted on said first support means for rotation in a plane parallel to said given axis; a mechanical hand mounted on said second support means for rotation about an axis aligned with said given axis; means for rotating said first support means; first gearing means for rotating said second support means; second gearing means for rotating said mechanical hand; first transmission means connecting said first gearing means and said second gearing means for operating the same in unison to prevent said mechanical hand being undesirably rotated through said second gearing means when operating said gearing means for rotating said second support means only; and, second transmission means connecting said means for rotating said first support means and said first transmission means for preventing said second support means and said mechanical hand being undesirably rotated through said first gearing means and said second gearing means when operating said means for rotating said first support means only.
