Linear motion power amplifier

Claim 1

A POWER AMPLIFIER COMPRISING AN INPUT ELEMENT MOUNTED FOR GENERALLY LINEAR MOVEMENT BETWEEN A LARGE NUMBER OF SUCCESSIVE POSITIONS, AN OUTPUT ELEMENT MOUNTED FOR GENERALLY LINEAR MOVEMENT IN ESSENTIALLY THE SAME DIRECTION AS SAID INPUT ELEMENT AND BETWEEN A LARGE NUMBER OF SUCCESSIVE POSITIONS CORRESPONDING RESPECTIVELY TO SAID POSITIONS OF THE INPUT ELEMENT, A CONNECTION ATTACHING SAID INPUT ELEMENT TO SAID OUTPUT ELEMENT FOR SWINGING MOVEMENT RELATIVE THERETO IN A DIRECTION TO ADVANCE LINEARLY RELATIVE TO THE OUTPUT ELEMENT AND TO SIMULTANEOUSLY SHIFT TRANSVERSELY OF SAID DIRECTION OF LINEAR MOVEMENT, POWER DRIVEN ROTARY DRIVE MEANS, RELEASABLE POWER TRANSMITTING MEANS CONNECTED TO SAID OUTPUT ELEMENT TO DRIVE IT LINEARLY BUT SHIFTABLE LATERALLY RELATIVE THERETO BETWEEN DIFFERENT POSITIONS, SAID POWER TRANSMITTING MEANS AND SAID ROTARY DRIVE MEANS HAVING FACES ENGAGEABLE IN SAID DIFFERENT POSITIONS OF THE POWER TRANSMITTING MEANS TO DRIVE THE POWER TRANSMITTING MEANS IN OPPOSITE LINEAR DIRECTIONS AND THEREBY DRIVE THE OUTPUT ELEMENT IN OPPOSITE LINEAR DIRECTIONS, AND AUTOMATIC FOLLOW-UP MEANS FOR SHIFTING SAID POWER TRANSMITTING MEANS BETWEEN SAID DIFFERENT POSITIONS IN RESPONSE TO SAID SWINGING MOVEMENT OF THE INPUT ELEMENT RELATIVE TO THE OUTPUT ELEMENT AND IN A RELATION CAUSING SAID ROTARY DRIVE MEANS TO POWER ACTUATE THE OUTPUT ELEMENT LINEARLY TO SAID DIFFERENT POSITION THEREOF IN ESSENTIAL CORRESPONDENCE WITH THE LINEAR MOVEMENT OF SAID INPUT ELEMENT TO SAID DIFFERENT CORRESPONDING POSITIONS THEREOF.
