Claim 3

An electromechanical memory positioning system comprising: an electrically energizable drive means mechanically connectable to a positionable device to move the device to a predetermined desired position when the device is displaced therefrom; a movable member mechanically connected to said drive means for movement in response to the movement of the positionable device; a contoured electrically conductive surface formed on said movable member, said contoured surface being contoured to form at least one area of nonconductance thereon; switch means positioned adjacent said conductive surface, said switch means having contact points engageable with said conductive surface and electrically connectable to said drive means; a selector switch for connection to a power source and connectable to said switch means for energizing said drive means through said switch means and said conductive surface when said positionable device is displaced from said desired position; thereby moving said positionable device and said movable member until at least one of said contact points of said switch means engages the nonconductive area of said conductive surface thereby deenergizing said drive means and stopping said positionable device at said desired position, said movable member is a driven disc mounted for rotation about its axis, and said conductive surface is on one side of the disc, a second contoured electrically conductive surface mounted on the other side of said disc and further including second switch means for controlling the energization of said drive means in a second direction, means for laterally shifting said disc so as to cause the metal plates secured to the sides thereof to selectively engage only one switch means at a time, said means for laterally shifting said disc comprising a transverse shaft supported for transverse motion relative to said disc, a selector lever mounted on said transverse shaft, said disc mounted on a disc shaft and mounted for movement along its axis which extends at a right angle to said transverse shaft, a shoulder attached to said disc shaft, a link attached to said transverse shaft and engageable with said shoulder to move said disc shaft along its axis, said movable member has a notch, and a locking pawl engageable with said notch and said transverse shaft coupled to said pawl to hold it in said notch when said transverse shaft is moved along its axis to a locking position.

Claim 4

An electromechanical memory positioning system comprising: an electrically energizable drive means mechanically connectable to a positionable device to move the device to a predetermined desired position when the device is displaced therefrom; a movable member mechanically connected to said drive means for movement in response to the movement of the positionable device; a contoured electrically conductive surface formed on said movable member, said contoured surface being contoured to form at least one area of nonconductance thereon; switch means positioned adjacent said conductive surface, said switch means having contact points engageable with said conductive surface and electrically connectable to said drive means; a selector switch for connection to a power source and connectable to said switch means for energizing said drive means through said switch means and said conductive surface when said positionable device is displaced from said desired position; thereby moving said positionable device and said movable member until at least one of said contact points of said switch means engages the nonconductive area of said conductive surface thereby deenergizing said drive means and stopping said positionable device at said desired position, said movable member is a driven disc mounted for rotation about its axis, and said conductive surface is on one side of the disc, a second contoured electrically conductive surface mounted on the other side of said disc and further including second switch means for controlling the energization of said drive means in a second direction, means for laterally shifting said disc so as to cause the metal plates secured to the sides thereof to selectively engage only one switch means at a time, said means for laterally shifting said disc comprising a transverse shaft supported for transverse motion relative to said disc, a selector lever mounted on said transverse shaft, said disc mounted on a disc shaft and mounted for movement along its axis which extends at a right angle to said transverse shaft, a shoulder attached to said disc shaft, a link attached to said transverse shaft and engageable with said shoulder to move said disc shaft along its axis, said movable member has a notch, and a locking pawl engageable with said notch and said transverse shaft coupled to said pawl to hold it in said notch when said transverse shaft is moved along its axis to a locking position.
