You don't know how long I have been looking for this info.  Thanks alot.  I will have to check out all the other info on this site.   My buddy refurbs/restores old Coke Machines and Gas Pumps.  He has done many old machines/pumps but got his first newer machine (late 70s - early 80s) and I was trying to figure out how to setup a free vend on it.  Again, thanks for the info.

Glad to help! send your thank-you note on the  back of a twenty dollar bill to... :p  anyway hope it helps! the diagram will help you sort out vending problems on most 115 volt AC
8-pin "Jones" connector style  machines, just be warned the "free-play" switch will have 115 Volts across it. so insulate it well & dont place it in a "wet" area such as a bottle opener slot, etc.

Diagram worked fine.  I used 14 gauge wire and a small Momentary PushButton rated for 115V AC mounted in the top of the Coin Return.  I used blades from replacement AC Plugs for the plug into the receptacle.  I used heat shrink tubing when possible and well wrapped electrical tap connections for the others. We left the Coin Mech unplugged for now, but may want to use both some time on the future.

After getting the Free Vend to work we found out that two of the selections did not work correctly.  One ended up being the brake on the cam mechanism that runs the microswitches for the selection motor. A little 3in1 oil on the arm solved it. The other was simply a connector that needed reseated due to the machine sitting for a long period unused.

Just thought you would like to know it all worked out well.

Hi!  I'm new to the vending world.  I just got a Dixie Narco model DNCB 168/99-5 with a CoinCo mechanism in it model # S75-9800B and wonder if the free play switch illustrated here will work on this model?  Also, if not, is there some way to set up a free vend on it? How do I tell what the year of Mfg. is for this machine?  This is a great site.  It appears you can get just about any info you need to get these machines up and running!  Glad I found you!    TIA, Tim

I want to make sure I get this correct. Line 1 & 7 is jumped together and tied into one side the push button switch. Then the other side/line goes to 3?

1 = 117 VAC (Hot)
2 = 117 VAC (Neutral)
3 = VEND RELAY - NORMALLY OPEN
4 = NC (No Connection)
5 = Exact Change - Normally Open (NEUTRAL)
6 = (HOT) ACCEPT COINS
7 = VEND RELAY-NORMALLY CLOSED (HOT)
8 = NC (No Connection)

I don't understand why the VEND RELAY (7) is listed as hot unless that is after you plug the coin mech in. I understand the VEND RELAY (3) as being open since this goes to the relay. When power is applied to the relay. It allows you to vend a pop. Also I found on the board if you jump say 1 to 5 it causes the correct change to stay on. This makes sence

Thanks,

ussexplorer

The purpose of pin 7 is to present a "ready to vend" (on/hot)signal back to the coinmech, conversly, it also gives the coinmech a "lockout" (off) signal, so it doesn't allow a multiple vend.

I would like to thank the board and especially JohnieG for the great info. on setting the coin mech to free play.  I missed the most recent diagram attachment but managed to get the free play set-up and work today.

I have a coke 63 that now vends bottles through the change door.  When you put your finger through, it raises the clear plastic coin door flap, which then hits the push switch and your off to the beer hall!

I've got another machine with a busted coin mech and may want to experiment with free vend on this one too.  Anyone else put the push button in another place?  I heard that a guy set one up at the bottom of a machine, so you gently tap it with your foot and it vends.  Anyways, thanks again guys!

Before throwing any of those broken coin mech.s away, you might want to cut that Jones plug off. They come in handy when installing a bypass switch.

Post by: glassbottlesrule on February 07, 2005, 04:42:10 pm
Sometimes I hack up the slug rejector on the mech so the contact switch can be placeso the coin return lever will hit it when pressed.  That way I can use the Jones plug and not have ugly wires hanging out of the socket.  You can Hide everything in the gutted mech and when you open the door it looks nice and stock.

Sure is. Just wire to the exposed wires under the Jones plug. All your doing is tripping the relay,
doesn’t really matter if you do it with a switch or coin mech.
Here’s what I did, I wanted to vend soda the usual way but have one column (button) for beer.
I wired a micro switch and stacked it on top of the selection button micro switch and
adjusted the timing so the selection switch would click before the relay switch. This setup
would vend free beer at the push of a button (pay for pop, but free beer. I always said it was
to keep from bootlegging).
As it turned out, the grandkids got the hang of playing with the beer button and I would find
my workbench full of beer that I would have to put back into the machine.
Now what I have is a remote car starter wired in by way of a relay. The remote start unit is 12v
so I took the 24v from the coin mech and ran it to one of those voltage reducers from JC Whitney
for 24-volt systems using 12-volt accessories in old cars. The antenna is hid behind the tag in the button.
If I want a beer I just press the start button on the remote. I have had lots of fun with this setup!
No more benches full of beer getting warm.

I recently bought a Cavalier CS64C and the wiring block I have doesn't look like the one in these diagrams.

Instead of "slots", I have a solid block with labeled colors on it (blue, yellow, purple, etc.) with corresponding wires.

Has anyone set one of these up for a free vend, and if so - how?

Hello

I made the momentary switch jusdt like in the diagram above, i found it holes 4, 7, and 8 dont seem to have any receptacles in them. Looks like it is the way it is made. Also switch seems to work just fine with only prongs 1 and 3 plugged in.

What is the exact purpose of plug 7? Am I in danger if I dont use it. I would like to hook the coin box up again while having the option of pushing the "secret button" for me and the wife.

Thanks again for any help:D

Pin #7 in the Jones connector (female socket) is generally used for a vending stack switch, that provides the coinmech. with a "ready to vend" signal, it may or may not be used on your machine, especially if yours is equipt with an additional vending relay (typically used in multi-button machines) it depends on which machine you have (which you didn't mention)

Hi Fellow pop fans,

I just got a late 60's or early '70's Vendo 156-276, I have worked in the vending world ten years ago, and I am a little rusty with the machines. I tried the free play setup on this machine and it worked once or twice. Is there anybody out there that knows about these machines? I need some help here.

Hi gang,

I figured out what the proplem was with my Vendo 156-276, for free vending. unlike the older machines in which you have to eather pull out the bottle or drop the can (or bottle), the coin mech holds the solonoid in  untill the cam rotates 10 deg. or so and vends. I just kept hitting the button, and the machine would vend, but if I held the button for one sec after I made my selection, it would vend like a dream. So for you newer machine owners, try holding the free play button for a second after making your selection it should work.

Marc

What you described sounded familiar.   If I am correct, that is somewhere at the bottom of the bottle door in between the door and the actual body of the machine.  If that is the case, then you should still have a jones plug near the coin mechanism (or where it should be) If you lift up the metal piece where the exterior coin slot is (it shoud be on a hinge that is locaed just under the sign)then the plug should be under their (at least it is on my machine)

Hope that helps

I recently picked up my old college machine from my sister. Originally received it directly from the local Pepsi man. I think it says Choice Vend CVC-223 on the side. Anyways, Pepsi doesn't just give away the coin mechs with the old machines, so I have never had one. tried the free vend diagram, but am having problems. it just keeps vending. not one can, but all until the rack is empty, or i unplug it.
any ideas?
thanks  :darn:

Title: Free play switch once more
Post by: johnieG on April 27, 2006, 08:51:50 pm
Looks like your vending relay's stuck ...or maybe your switch isn't "normally open" (N.O.) it should be a ( beware! technical talk follows  :p ) momentary, normally open type that is rated for 125 volts A.C. at at least 1/2 of an amp.

one way to tell is to push the button & hold it, if the machine STOPS vending youz gotta bass-ackward switch ( a normally closed type)


Title: Free play switch once more
Post by: on April 28, 2006, 08:37:46 pm
thanks for the info. tested the switch, again. and, again. checked it online and it shows that it is a normally open switch. must be the relay problem you mentioned. any ideas on how to test this?
thanks again.

Well, on a ChoiceVend, the once the vending cylce is started buy the coinmech/vending relay, the vending motor gearset
(located on the bottom of the stack that's malfunctioning) could have a broken/stripped gear that controls the cycle switch for that columns vending motor. if it's stuck in the "pre-load" position (which is controled by a little wire-rod that pokes out of the bottom under the columns tray area, see if this picture helps....

The correct male plug to use that plugs into the machine's changer socket is any one of these:

Cinch-Jones # P-408-CCT
Cinch-Jones # P-2408-CCT
Beau # P-5408-CCT
Molex # 38541-5408

Mouser Electronics (www.mouser.com) # 538-38541-5408

I also have the schematic wiring diagram to the WICO changer bypass testing unit, Stock # 72-4478. It's very easy to build this yourself and the switch with "credit established" LED can be installed in a project box.

Hey Ken - how is your bypass unit different from the free-vend switch?


Title: Free play switch once more
Post by: Ken Layton on June 15, 2006, 06:26:43 pm
WICO (now sadly out of business) built these Changer Bypass units as part of their vending machine division's test equipment line. I used to have one when I worked for a local longtime game and vending machine operator.

You simply unplug the existing changer, plug this unit in and push the free vend button. If everything is functioning ok in the machine, the "credit established" LED would light up and you have a free vend.

So it's a free vend switch that connects to a jones plug rather than loose spade connectors?

Yes, that's exactly right---a simple plug n play device with a Jones plug on it.

The amusement/vending operator I used to work for had tons of Automatic Products brand cigarette machines with single price Mars TRC6800H changers in 'em. This device came in handy testing the machine.

Why exactly would you want to do this ? If you wanted to rig up a free switch inside a broken coin mech you'd just use the jones plug and empty shell and mount a microswitch under the coin return lever (so it credits when you hit the coin return)

Yes, either wire the free vend switch to the terminals from behind the jones socket, or use a piggy-back harness from a DBA (where the DBA plug would go into the jones socket and the coin mech would piggy back on top of that).


Title: Free play switch once more
Post by: on August 03, 2006, 09:09:18 pm
OK, here it goes. I couldn't get an answer on how to set the pricing on my Coinco AS 9400. No matter what combination I tried I just could not get it to vend. I even went so far as to write coinco, and they faxed me a manual for my changer. It was no help, it really doesn't say how to set the price and if you know how the max is 20 cents the normal is 15 cents. I don't like that. Either a dime or a quarter is what I want. So here is what I did. I took the freeplay info and made up a small wiring harness but rather than putting a momentary contact pushbutton on the end and drilling holes or mounting it to the coin return button, I put two female spade connectors on the other end of the wires. You might ask why, well this is the reason, on the back of my coinco AS 9400 is a set of micro switches one of which is tripped when a quarter goes through the slug rejector. So I plugged my freeplay harness into it using the female spade connectors. To make it work I had to remove the small springs from the quarter and nickel/dime coin return electromagnets (behind the slug rejector). Simply removing the small spring from one end allows the coin to pass normally through the slug rejector. Under normal operating of the coin mech these are energized and allow a coin to go through. If you use the free play harness and don't undo the springs your coins will pass right through to the coin return. This simple fix now allows me to purchase a pop from my machine with a quarter! :p

Skeleton man, everything worked in my coin mech as far as the adjustable cam rotating. I could cause it to rotate by tripping the wires with my fingers and get it to vend. The problem was no way to know what position to put the cams into. There is a set sequence - switch one is a Zero cam Switch two is a 15 cent stepper Switch three is a 20 cent stepper and Switch four is the Vend switch. In order to vend at the correct price all the adjustable cams need to be in a specific order (previous owner was in there messing with it, perhaps this is why I paid so little for the machine). No one seems to be able to tell me what they are and as I said the best that coin mech can do is 15 or 20 cents. This is a low budget garage project, I paid 202 dollars for this working soda machine to put cans in for my family. I couldn't see spending the money on this machine for a coin mech. So this works and does not do anything to damage the original coin mech. :drinking:  At this time I also own a restored V 39 and a WC 52 T.

I have a Rock-ola Pepsi 5 button machine. This is my first pepsi machine. I tried the Free Play Switch on it but when i press the free vend button i stalled it make a snap sound and when a selection is pushed i get no response. I have also tried the coin mech, and the coins just drop straight through. I did plug the coin mech back in before trying. Any thoughts?

Just my two sense but I've run into connection problems with the Jones plug. I bend the prongs out a little to get a better tighter fit and it has worked every time. Ive gotten new coin mechs and thought they didn't work until I did this. Just a thought :biggrin:

Post by: mznb1u on March 19, 2008, 11:11:10 pm
I learned not to play with electricity about 40 years ago when my dad was changing the blade on the lawnmower.  He told me to hold the spark plug wire so it did not make contact with the plug.  Unfortunately, he did not tell me to hold it by the insulated part of the wire.  The blade turned and  . . . arm still hurts everytime I think about it!

Anyway, I looked at the diagram and it look fairly straight forward.  I assume this will work on a Cavalier USS 8 64?

Can really screw the machine up if I do something wrong?

What gauge wire should I use?

Where is a good spot to hide the switch so it will be accessible but not show.  I want to avoid making any visible holes on the machine.

THANKS!

I have a Cavalier USS 12 96 with a Coinco S75-9800A.  When I went to hook up a free vend switch following the diagram in this forum I found that there is no wire connected to pin 7.  So at least on mine there was no need to jumper 7 to 1.  I simply added a N.O. switch across 1 and three.  Seems to work fine.
