Jubilee jackpot mech

Postby titanic » Tue Mar 29, 2016 6:23 pm

Hi, I was wondering if anyone could help me with a problem I have run into?
I recently acquired a Jubilee International that has a double jackpot mechanism. I have never seen one of these and after some research can't find much help. The problem when I force a jackpot, the payout slide moves back but doesn't release the the two trap doors. I presume something has been removed to disable it. I can't find any close up pictures of a working mech and was wondering if anyone on here had any? Below are some photos of it still attached to the machine. I didn't want to remove it before asking for some advice on here. Like I said, I don't know what a functional one looks like so not sure if anything is wrong or missing.
Thanks

The jackpots don't both drop together.
Only one drops and they take it in turns, that way there's always one full.

I think it's the round wheel on the side that flips the choice of which one drops next.
Often when these won't trip it's for one of two reasons ......
Dried grease or missing spring stopping the flap from swinging free
Or: -
Jackpot mechanism not having reset from the last time due to dried grease or missing spring stopping the flap from resealing.

Check first that the linkage between the post on the payout slides and the jackpot is resetting the relevant flap when it's played. I think that's your first suspect.

Hi, badpenny thanks for the reply. The linkage from the slide does move the bits on the jackpot mech... the bit above the pin on the last picture that looks like a hook does move but doesn't open/close or do anything else to the mech. Like I say Im complete novice, so not sure what bits should be moving etc.

Is the jackpot reset or is one of the trap doors loose?

Both doors permanently open, you can "balance them closed" but the slightest touch and one or either of them or both will drop open again?

My machine is buried behind a fortune teller and a Duo-mat but if your problem can't be solved I'll move it out and take photos. For now though I think you really need to remove the JP (a) to clean it and (b) so you can manually operate it and get to know how it works. These are complex but fairly trouble free.

The problem will almost certainly be as BP says and the most likely part will be the switch gear that changes between the JP's. Did you realise that there is a system for alternating the coin flow to the JP's as well? Don't be worried about removing the JP, it comes off in one piece and will need a good clean anyway. Once off you can hand operate and see what goes on. Let us know how it goes and we can move on from there.

Thanks, will take it off later today as have already been warned by the other half, "you needn't think you're wasting all your day off, messing about with that bloody machine." :didact: Better take her shopping, then maybe I can "mess" with it bit more! Will let you know how I get on later.

OK update, was a bit fiddly getting some of the screws out, but managed to take the mech out. You were right, it is a lot easier to have a play and figure out how it works with it removed. I have got the gist of how it works. The first problem was the 2 sprung catches behind the first picture I posted, had fallen below where the arms go through so couldn't hold the doors in place. The doors stay in place fine now. The next problem was if you slowly turned the spindle at the payout slide side, it would release one of the doors. But on the next spin it didn't close it. I fixed this by loosening the bottom 2 screws of the 4 in the 4th picture down and extending that arm. In the 3rd picture down I think there is a pin missing, as about every 3rd spin the arm moves back, but isn't attached to anything. I presume thats what you ment about alternating the coin flow? The main problem now is the payout slide doesn't release the doors. The spindle can be rotated by hand to release one. It looks like there is a cog or something missing off the end? As above it is a hook which I presume pulls something round??

ok, first the jp coin feed, yes there should be a connection there,the wheel turns on every play but only operates the coin feed every other play so two coins fall into each JP before it switches over (very clever really)

yes there is a small part missing from the release side,quite easy to make but Id be very surprised if BP dosnt have one behind the mantel clock or treefrog dosnt have a box of a dozen...new ones. see the photo below

My guess is there was an attempt to make this a one JP machine at some time,hence the removal of the coin feed and the alternating door opener

Thank you for your help, and the photo. If anyone does have one please let me know if you want to sell it, if not I'll have a go at making something. Yea when I first looked at it, I wondered how it could fill both Windows. You are right it really is a clever addition. Think you are right as the machine had been butchered at some point, as well as the jackpot, the payout award glass had all the payout amounts scratched off the reel strips had been replaced with JPM ones? Don't match any wins and there is a lemon on all 3 reels! Plus various missing parts! Going to be bit of work, but thats why I bought it! :D
