Claim 1
Independent Claim
176 words
IN A RECORDING DECELEROMETER, THE COMBINATION COMPRISING A SLIDEWAY MOUNTED GENERALLY PARALLEL TO THE PATH OF DECELERATING MOVEMENT, AN INERTIAL MEMBER SLIDABLY MOUNTED ON SAID SLIDEWAY, A RECORDING MEMBER, MEANS FOR MOUNTING SAID RECORDING MEMBER AT A POSITON ADJACENT SAID SLIDEWAY FOR RECORDING MOVEMENT RELATIVE TO A CHART, A FLEXIBLE CORD CONNECTED AT ITS ENDS TO SAID INERTIAL MEMBER AND TO SAID RECORDING MEMBER MEANS SUPPORTING SAID CORD FOR FLEXING MOVEMENT THEREOF ADJACENT A NEUTRAL POSITION OF SAID INERTIAL MEMBER SO THAT MOVEMENT OF SAID INERTIAL MEMBER IN EITHER DIRECTION ALONG SAID SLIDEWAY INDUCES CORRESPONDING MOVEMENTS OF THE ADJACENT PORTIONS OF SAID RECORDING MEMBER, AND MEANS FOR BIASING SAID RECORDING MEMBER PORTION TO A BASE POSITION THEREOF CORRESPONDING TO SAID NEUTRAL POSITION OF THE INERTIAL MEMBER SO THAT SAID INERTIAL MEMBER IS RETURNED TO ITS NEUTRAL POSITION FOLLOWING DECELERATION INDUCED MOVEMENT THEREOF, SAID RECORDING MEMBER IS A PIVOTED ARM HAVING A RECORDING STYLUS THEREON, THE PIVOT MOUNTING OF SIAD RECORDING ARM BEING DISPOSED SUCH THAT THE STYLUS BEARING PORTION THEREOF MOVES SUBSTANTIALLY TRANSVERSELY OF SAID SLIDEWAY.
