The core of the invention is a modification of the divide by two flipflop to retain the marble that 
falls off the right side, and keep it until the flipflop is flipped to the left by the next marble.
See small diagram above right.  The retention of this extra marble allows the state of the marble 
accumulator to be dumped.  The adder would just as well add without it, but the number would have 
to be read off by the angle of the rockers, rather than have the device dump the count out.  
Really, if such an adder were integrated into a hypothetical marble computer, reading out the result 
as a series of marbles would be an essential element.
