Self-locking transmission mechanism

Abstract

Abstract A SELF-LOCKING TRANSMISSION MECHANISM FOR TRANSMITTING ROTATION OF A DRIVE SHAFT INTO ROTATION OFF A DRIVEN SHAFT THROUGH THE USE OF DRIVE STUDS CONNECTED TO THE DRIVE SHAFT AND ACTING THROUGH A PAIR OF SPRING STRIPS TO ROTATE A TRANSMISSION BLOCK TO WHICH THE DRIVEN SHAFT IS CONNECTED. THE SPRING STRIPS ARE DISPOSED WITHIN A HOUSING AND HAVE ARCUATE CENTRAL PORTIONS DISPOSED AT AN INTERIOR ANNULAR WALL PORTION OF THE HOUSING, SPACER PORTIONS, EXTENDING INWARDLY FROM THE ENDS OF THE ARCUATE PORTIONS, AND INTURNED END PORTIONS EXTENDING FROM THE INNER ENDS OF THE SPACER PORTIONS TO OUTER EDGES THAT ARE ENGAGEABLE WITH SURFACES OF THE TRANSMISSION BLOCK. THE INTURNED END PORTIONS ARE ENGAGED BY THE DRIVE STUDS OF BIAS THE SPRING STRIPS INWARDLY FOR MOVEMENT WITHOUT SIGNIFICANT DRUG DURING DRIVE TRANSMITTING ROTATION OF THE DRIVE SHAFT, AND ARE ENGAGED BY THE TRANSMISSION BLOCK TO BIAS THE SPRING STRIPS OUTWARDLY AND THEREBY IMPOSE A SELF-LOCKING DRAG AGAINST THE HOUSING WALL PORTION UPON ATTEMPTED ROTATION OF THE DRIVEN SHAFT INDEPENDENT OF ROTATION OF THE DRIVE SHAFT. SELF-LOCKING IS ALSO POSITIVELY OBTAINED BY JAMMING OF THE SPACER PORTIONS BETWEEN THE HOUSING WALL PORTION AND THE TRANSMISSION BLOCK UPON ATTEMPTED INDEPENDENT ROTATION OF THE DRIVEN SHAFT.
