Jamieson’s Autofruit range 1962 - 64

Postby jamiesonautomatics » Tue Aug 27, 2019 9:10 pm

I’ve recently had passed onto me some photo’s compiled by my grandfather the late Arthur Jamieson that I thought I’d like to share. These show some of the Jamieson machines in the “Autofruit” range Circa Sept 62 - Oct 64 in different guises.
As some of you know, I have a “Luck Throw” version that I’m in the process of restoring. As you can see from the “internal wiring” photo at the top it shows two small motors. The right hand one driving the cam drive & the left hand one operates a switch ( I think ? Because this motor is missing in my machine) so has anyone got one of these machines with two motors ?? If so what rpm is it ??

What a superb selection of photographs.
The Jamieson's machines were always my favourites at the time, and once I actually managed to OWN one, I started to appreciate the ingenuity which had been built into them.
The 'AUTOFRUITS' I have are 'Autofruit', 'Royal Ascot', 'Top Ten', 'Lucky Throw' and just the glass for 'Big Top'.
'Gold Cup' has so far eluded me.
I am aware of alternative versions of these, and I also have 'Starlet', which I imagine is an earlier type, not having the variator fitted.
I'll have a look at the variator motor on my 'Lucky Throw' when I get home tonight, and post the final RPM for you.
There are two different cam profiles, one with four evenly-spaced notches, and one with unequal spacing. They are probably just developments over time, though, and not specific to each version. The machine runs fine without the variator assembly; it just means that the sequence is shorter, giving small boys in the '60s a better chance of working it out!
Thanks for the pics. I'm always on the look-out for anything Jamieson-related, although the chances of finding a six-way are remote.

The work room picture is amazing. It would appear you had to bring in your own work stool.

If you could post a picture of the ” variator assembly” etc that would be great so i can see what operates the switch ??
My machine had a replacement cam motor held in place with some 60’s mechano !!
I’ve replaced this motor but the sequence seems a bit fast so info on this motor rpm would be appreciated

I’m also hoping to add to the Jamieson collection in the future - keeping them in the family so to speak - also to show my kids what their great grandad created!!

Cheers

Sorry to hear you are struggling with the motor speed, when I found you the Lucky Throw machine I recommended a 12 rpm motor thinking it would be ok for the job, I think the original Crouzet motor would have been 10 rpm, so not a lot of speed difference ?? I think a 6 rpm would be too slow??

"Crouzet" motors of this kind were only produced in a fixed speed range, starting with 1 rpm / 2 rpm / 3rpm / 4 rpm /5 rpm / 6 rpm / 10 rpm/ 15 rpm / 20 rpm / 30 rpm / 40 rpm / & 60 rpm.

a new motor with the same footprint would cost you about £90 today,
second hand motors in working order are rare, but they do come up from time to time.

best of luck with the project. :cool:

The variator motor turns at 5rpm. This is the left-hand motor in the inside photograph, the one between the odds adjuster and the main sequence controller.
The speed of this variator will have no effect on the speed of the game. The right-hand motor controls the game length. It runs at 6rpm, and so the game lasts 10 seconds.
The rate at which the symbols change is controlled by the third motor; the one which drives the wiper around the ring of contact posts at the bottom right of the cabinet. This is the device that gives the machine its familiar 'clack'.
The variator cam seems to come in two types. One has eleven (not four-my defective memory) equally-spaced notches, the other has four, a gap, five, and another gap.
The only purpose of the variator is to lengthen the gap between the main controller starting the selector (which is a fixed point in the game) and the selector actually starting. Otherwise, the selector would move a fixed number of 'clicks' every game, and the sequence could therefore be calculated.
I would leave the variator until last. Simply strap the contacts together until the rest of the machine is running correctly, and attend to it later.

Hi - thanks for the reply
As you know the machine you supplied had a cobbled together mechano motor thing fitted so I fitted the new 12rpm motor - it initially went backwards and jammed on the cams but I sorted that !! The only issue with this motor speed was that it struggled to pay out in enough time for a 1/- win - it pays of 2x1d coins @ a time so needs 5 pulses before it moves onto the next game - if my basic understanding of the sequence was correct ? I cleaned up all the payout shoot and mag bolt etc and it was just about managing it. I could see from the photo's I posted that some of the machines were fitted with two motors - it was obvious that mine had something missing - so was intrigued as to what was missing.
Thanks again for the reply much appreciated

That's exactly the info I was looking for - I've been asking my dad but he couldn't remember due to the amount of different machines they made and it was back in the 60's!! - he can remember making the selectors when he was younger - I'll have to get him to rewire mine as it's nearly worn out with all those years of 'clicking'
I've seen people post wiring diagrams for some other machines - do you know of any for these??

Thanks again for the info - much appreciated
