Analog magnetic tape-controlled machine

Claim 1

A MAGNETIC TAPE-CONTROLLED MACHINE FOR REPRODUCING A PREDETERMIEND CONFIGURATION UPON A WORKPIECE IN RESPONSE TO INSTRUCTIONS RECORDED UPON THE MAGNETIC TAPE BY LINE-FOLLOWING OPERATIONS UPON CORRESPONDING VIEWS OF THE WORKPIECE, SAID MACHINE COMPRISING A WORKPIECE HOLDING STRUCTURE HAVING MEANS FOR MOUNTING AN UNFINISHED WORKPIECE THEREON, AN UPRIGHT FRAME STRUCTURE DISPOSED IN HORIZONTALLYSPACED RELATIONSHIP TO SAID WORKPIECE HOLDING STRUCTURE, VERTICAL SLIDE MECHANISM MOUNTED FOR VERTICAL TRAVEL ALONG SAID UPRIGHT FRAME STRUCTURE, VERTICAL SLIDE MECHANISM MOTIVE MEANS OPERATIVELY CONNECTED TO SAID VERTICAL STRUCTURE FOR MOVING THE SAME VERTICALLY ALONG SAID UPRIGHT FRAME STRUCTURE, A HORIZONTAL TRANSVERSE SLIDE MOUNTED FOR HORIZONTAL TRAVEL ALONG SAID VERTICAL SLIDE TOWARD AND AWAY FROM SAID WORKPIECE HOLDING STRUCTURE, HORIZONTAL TRANSVERSE SLIDE MOTIVE MEANS OPERATIVELY CONNECTED TO SAID HORIZONTAL TRANSVERSE SLIDE FOR MOVING THE SAME TOWARD AND AWAY FROM SAID WORKPIECE HOLDING STRUCTURE, A HORIZONTAL CROSS SUPPORT PIVOTALLY MOUNTED ON SAID HORIZONTAL TRANSVERSE SLIDE FOR SWINGING AROUND A HORIZONTAL PIVOT AXIS, A HORIZONTAL CROSS CARRIAGE MOUNTED ON SAID CROSS SUPPORT FOR HORIZONTAL TRAVEL THEREALONG SUBSTANTIALLY PARALLEL TO SAID WORKPIECE HOLDING STRUCTURE, HORIZONTAL CROSS CARRIAGE MOTIVE MEANS OPERATIVELY CONNECTED TO SAID HORIZONTAL CROSS CARRIAGE FOR MOVING THE SAME SUBSTANTIALLY PARALLEL TO SAID WORKPIECE HOLDING STRUCTURE, A TOOL HOLDING STRUCTURE MOUNTED ON SAID HORIZONTAL CROSS CARRIAGE AND INCLUDING A POWER-DRIVEN ROTARY MACHINING TOOL HOLDER DISPOSED ADJACENT SAID WORKPIECE HOLDING STRUCTURE, A MAGNETIC TAPE READER ADAPTED TO RECEIVE THE MULTICHANNEL MAGNETIC MACHINING INSTRUCTION TAPE AND TRANSFORM THE RECORDATIONS THEREON INTO ELECTRICAL SIGNAL IMPULSES, AN ELECTRIC CIRCUIT CONNECTING SAID TAPE READER TO THE RESPECTIVE MOTIVE MEANS CORRESPONDING TO THE SEVERAL INSTRUCTION CHANNELS OF THE MAGNETIC TAPE FOR TRANSMITTING THE ELECTRIC IMPULSES THEREFROM TO SAID INSPECTIVE MOTIVE MEANS WHEREBY THE AXIS OF ROTATION OF SAID ROTARY TOOL HOLDER IS CONSTANTLY MAINTAINED BY A PREDETERMINED COMPOUND ANGLE RELATIVELY TO REFERENCE CO-ORDINATES IN RESPONSE TO INSTRUCTIONS TRANSMITTED THERETO FROM SAID TAPE, SAID HORIZONTAL PIVOT AXIS OF HORIZONTAL CROSS SUPPORT BEING DISPOSED SUBSTANTIALLY COINCIDENT WITH THE TIP OF THE ROTARY MACHINING TOOL IN SAID ROTARY MACHINE TOOL HOLDER, AND HORIZONTAL CROSS SUPPORT SWINGING MOTIVE MEANS CONNECTED TO SAID ELECTRICAL CIRCUIT AND OPERATIVELY CONNECTED TO SAID HORIZONTAL CROSS SUPPORT FOR SWINGING SAID HORIZONTAL CROSS SUPPORT AROUND SAID HORIZONTAL PIVOT AXIS IN RESPONSE TO ELECTRIC IMPULSES TRANSMITTED THERETO FROM SAID TAPE READER.
