Machine for generating ellipsoidal surface

Claim 1

A MACHINE FOR GENERATING A TRUE ELLIPSOIDAL SURFACE OF REVOLUTION ON A RIGID BODY, SAID MACHINE COMPRISING A COMBINATION OF COACTING MACHINE PARTS WHICH ARE; A FRAME, A ROTATABLE WORKSHAFT, MEANS FOR SECURING SAID BODY ON SAID SHAFT WITH THE MAJOR AXIS OF SAID SURFACE COAXIAL THEREWITH, POWER MEANS OPERATIVELY CONNECTED TO ROTATE SAID SHAFT, A FIRST MOUNTING MEMBER ON WHICH SAID WORKSHAFT AND POWER MEANS CONNECTED FOR ROTATING SAID WORKSHAFT ARE OPERATIVELY ASSEMBLED, FIRST PIVOT MEANS WHICH ARE CONSTRUCTED IN FIXED POSITION IN SAID FIRST MOUNTING MEMBER AND ARE AXIALLY ALIGNED IN THE EQUATORIAL PLANE OF SAID ELLIPSOIDAL SURFACE IN SPACED RELATION TO SAID SRFACE, SAID FIRST MOUNTING MEMBER BEING ANGULARLY MOVABLE RELATIVE TO SAID FRAME IN A PLANE WHICH CONTAINS THE MAJOR AXIS OF SAID SURFACE ABOUT SAID PIVOT MEANS DURING GENERATION OF SAID SURFACE, A SECOND MOUNTING MEMBER WHICH CARRIES A FORMING TOOL AND IS MOUNTED IN A STATIONARY POSITION ON SAID FRAME, A TOOL HEAD PIVOTALLY MOUNTED ON SAID SECOND MEMBER, A SECOND PIVOT MEANS FORMED AXIALLY PARALLEL TO THE FIRST PIVOT MEANS ON THE TOOL HEAD AND SECOND MOUNTING MEMBER COOPERATIVELY AT A DISTANCE EQUAL TO THE SEMI-MAJOR AXIS OF THE ELLIPSOIDAL SURFACE AWAY FROM THE FIRST PIVOT MEANS AND COPLANAR THEREWITH SO THAT SAID TOOL HEAD MAY TURN THEREON, A FORMING TOOL OPERATIVELY MOUNTED ON SAID TOOL HEAD, SAID TOOL BEING CHARACTERIZED BY AN ELONGATED MACHINING SURFACE WHICH IS POSITIONED SUBSTANTIALLY COPLANAR WITH SAID MAJOR AXIS INCLUDES A POINT ON THE AXIS OF THE SECOND PIVOT MEANS,
