Enough of all these modern posts and queries, about time for some Ye Olde Tyme machinery again. Recently started work on this 1928 Essex "Stock Exchange" which is a sister to the "Corn Exchange" and uses the same mech - well, so I thought. Took me a little while to figure out what was going on and why this machine didn't quite make sense to what I'm used to, as it has been years since I've restored the last example.
There are totally different coin payout castings, plus added machinery for an added feature I've never seen before. Which is in fact a mystery free play coin return. And very cleverly it uses the same slots cut into the main payout wheel to accomplish this.
After starting play and turning the handle there is a brass lever that either hits the inside of the main wheel and stops its travel, or when it matches with one of the payout slots it can move further. Through some links this in turn allows a flap to move into place which deflects the Penny into a special chute in the coin payout casting, to return to the payout cup! This never occurs on a pre-winning play, (this is a future pay machine, so you know at the start of each play if and what the machine will pay out).
Appears to be factory made, as it's so well integrated into the machine and made of lots of high quality castings. Can't imagine an operator going to this amount of trouble just for a free play feature.
