AE L-652 Metal Wall Monophone Wiring Diagram
« on: July 08, 2013, 04:20:29 PM »
Here's a diagram that might be useful. Left click twice on pic to enlarge.

Hi Stub:

Here is a diagram of a very similar looking phone to the model 44 you show. This one began life as a magneto set before being changed over to a common battery set and the magneto being removed  However, its diagram is damaged around the dial area - I would love to get more information about what the correct designation of this phone would be, as well as a drawing in better condition.

The lower text includes information on changing it over from magneto to common battery, and the magneto has been removed, leaving only the crank hole to its right.

I have re-done this slightly to re-add the missing portions and to clean up the drawing.  Left click twice on pic to enlarge.

Dave

Note: This drawing is now completely verified, and the phone performs flawlessly on either local or common battery.

Dave,
         Do you have a copy of  OLD-TIME TELEPHONES  2nd Edition by Ralph Meyer? I found your induction coil on pg. 145. Your phone looks like it could be one type of AE - 60 with AE's isolation circuit, pg 155 - 160. Picture of phone on pg. 245 . 1st one I've seen!! I have a Type - 60 local battery (Y1217 ) that does not have the wiring to convert it to common battery. NICE find!!!!!!!!!

Hi Stub:

Actually, I have two copies of Ralph's book but never thought to look at it. Yes, I thought it was neat the way it was made convertible to common battery. I got the drawing cleaned up much more, and it is a lot easier to follow now.

I would guess it was converted many years ago, but it was designed to be converted. I must have a look at the book tomorrow if I feel well enough to go over to the museum!

The numbering on it would be in keeping with type 60 or at least a variation... It is the first I have seen of this type - in fact when I purchased it, I thought it was a type 44.

Hi Stub and all:

I think I have the AE 652 wiring diagram cleaned up as much as I can. When I bought the phone, the dial had been disconnected, and since the dial part of the internal schematic was obliterated, I wanted to make sure I had the phone working 100% before I fixed up the drawing to add the dial wiring to the damaged area. The dial area had previously been so discolored that it was impossible to see the wiring. So, it is all there now, although if I were better at Photoshop, I could have probably done a better job at recreating the dial portion.

Anyway, it is accurate, though a bit messy.

One interesting thing about that phone, is someone had installed a Switchcraft SPST toggle switch in the old magneto crank hole (at least they re-used the hole and didn't drill a hole), and connected it to the old magneto wires. This, of course, when the switch was toggled on, put a short across the line, making it effectively a "make busy" switch. I can't figure out why anyone would do that, unless they wanted it  that way so they could turn on the switch, hang up the phone, and use that as a "hold" function.

This switch has of course been removed, and the magneto connections insulated from each other as they should be.

Anyway, certainly is an interesting phone...

Now, does anyone have a spare AE dial center for this? It is also missing one dial mounting screw. That is about all needed now to complete its restoration.

Also, wondering if anyone has an AE catalog listing showing this model - I would love to make an accurate determination of its age. It is remarkable preserved - almost no scratches, and though the outer paint had dulled, it was 100% intact, and a little rubbing compound restored its finish entirely.

Dave,
         Glad you are up and going today. One question, are the 2nd and 5th hookswitch contacts supposed to be connected together  going to the 1st contact on the pulsing springs?  stub
Ok, you lost me there - which way are you counting the hookswitch contacts l-r or r-l?

Dave,
        The connection I was asking about is a stray line on the 1st diagram. The green wire, from capacitor,  looks like it is tied to the blk- wht going to the plusing springs. On the your last pic it is not connected.  stub
Yes, it is.... Oh, I see what you are talking about - it isn't connected to the dial - Got'cha now. Yes, it is a photoshop error I didn't catch.. Told you I had only limited drawing ability in PS :) You have better eyes than I do!

Hi Stub:

Well, I am glad that you mentioned it - it just took me a little while to understand what you were trying to point out. I wish I could have found a better original drawing as my eyes and my PS ability are pretty poor. Great with photos,, but lousy with drawings  :) If you note any other errors in it, please mention them to me, though it may take me a little while to understand which area you are talking about as it did this time. I do want it to be as accurate as possible, unfortunately, there were areas completely obliterated in the original.

Dave ,
          Did you supply 3 volts  DC to 5 and 6 ? Neg to 5 and pos. to 6 . Did you find your copy of Ralph's book ? Maybe pg. 159- 160 will help.
          My 60 looks like yours but the induction coil was there but removed and no retardation coil and no wiring diagram.
          When you get this one to working maybe I can get you to help me get this one working.  stub
Hi Stub:

Yes, I am perusing Ralph's write-up right now.... Maybe I am mis-understanding something, though, but isn't the phone supposed to be able to get its power from a common battery line? (the whole idea of the arrangement:??) The drawing states if used common battery, omit the battery and move "X" to the L2 terminal.

I see Ralph's drawings where he shows a battery in series with the induction coil primary and mic element... Worth a try, though...

Dave ,
           No dial on phones on pg. 159. The dial still looks like it is shunted when at rest.
          Go back to reply 14.  stub
That is why I wish I had an unadulterated original drawing for it.... But this was all I was left with. The dial itself is dialing well...

I'm missing something, but we will figure that out. I will tackle it again later on and see if I get anywhere. Of course when everything is 100%, I will again update the drawing if there are changes to be made.

Did you ever find an induction coil for yours? I notice yours is also a triple winding coil, but with different winding resistances from this one...

Time to take a break and will come back to it later!

Hi Everyone. After some problems figuring out the dial wiring for this phone, we have all problems resolved, and the drawing has been updated.

The phone works 100% on the BK Analyzer, perfect dialing, perfect ring, perfect and loud audio, in fact one of my nicer sounding phones.

Thanks to Stub, who assisted me as we figured out the correct dial wiring. We did have it correct, only the crosswise shorting bar between the shunt springs and the shorting springs should not have been there.

The drawing is now 100% correct!

Still looking for a dial center for this phone. I have WE, but no AE.

Nice job, Dave!
Glad to hear it is performing properly.

Now if someone who is adept at photoshop could clean up both of these drawings and put them in our wiring section..........
