Attached are pictures of the 09 coil that is in question. We have done a handful of these early coils but have never seen one with this type of frame and re-enforcing ribs. Any info would be appreciated.
That's pretty cool. It kind of reminds me of the fishplate on the frame of the early 1909 cars. Oops. Not strong enough!
Others may not know that the early stamped coil frames kind of wobbled. Later Ford came out with the cast (forged?) frame that was much more rigid.
Do you think it is a transitional one that had reinforcements added to make it more rigid until the heavier units were available? Or does it look like the work of a very skilled blacksmith?
I've got a feeling I'm gonna learn something here...
: ^ )
Keith, this is a learning experience for all of us. I had to learn how to re-size and post pictures. The reason for posting these pictures Kim Dobbin's told me he took a coil like this out of his car #314. I know this coil will only work with 1/2 inch magnets. If you look at the frame it has the same holes as used on the round double stack coil which was cast, at first we taught this one was cast however we found this stamped coil to be the same gauge as the oil pan. If indeed this was made by a skilled blacksmith he was outstanding. I hope someone can shed some light on this subject.
Is the gray one the earlier version? Do you know when it was used?
I have only seen one,and did not look at it closely,but it was similar to the one on the right.
From the Encyclopedia.

Steve the coil to the right (gray) is from 09 thru 11 it uses 1/4 inch wide wire, the one on the left is the earlier coil and uses 3/8 inch wide wire. John Page's post above answers the question about the holes in the frame however the re-enforcing ribs are still in question. The coil on the left supposedly came our of car 25XX. I have a couple of more pictures, time permitting I will post them later.
A couple of more pictures. This would be the front view notice the difference in the spool surface. The early one is completely round the one on the right has part of the circumference removed.
This is S/N 904's magneto. The magnets are very thin compared to later ones. Wally rewound the coil ring several years ago.
Wally the one in the first photos was for the first 500 cars I think. Here is the parts catalog picture for the early cars. Notice the holes in the coil ring plate are like the one in your first photo.
Wally, i cant find a full picture of the field coil out of my early 09, but here are a couple of partial pictures. Mine is the same as yours, except for the reinforcements which were probably added later. Kim
I wish to thank the hobbyist's that replied to my post regarding the 09 field coil. I'm sure there are many asking why spend time on this subject. That part is inside the engine and no-one sees it. The reason for me to bring this subject up was to gain some additional knowledge. I know of many brass and later vintage cars that have had alterations. The problem is if we do not have sufficient knowledge it could pose problems when replacing parts.
The magneto was a problem in the early years and it is evident that changes were being made to correct the problem. John Page's post indicates the stamped steel coil with holes was used thru car 17,500. Royce posted pictures of his 09 S/N 904 that is a solid frame with no holes. He also posted a picture of a parts catalog that showed the coil frame with holes in it for the first 500 cars. Kim Dobbins posted pictures of his early 09 coil and that one has the holes.
Is it possible the coil I have was an attempted fix to the vibration problem that was inherent with those early filed coils? When Ford changed to the oval double stack there were three different styles, the first being a cast coil similar to the round double stack, later he added re-enforcing ribs on either side of the coil, the final oval double stack had the inner ring cast around the entire inner circle. This style coil continued on all remaining single stack coils.
Royce you did a fine job on rebuilding that field coil, I did find it interesting the way you did the winding and insulating the sides of the wire from the steel frame, very innovative.
Again thanks to all.
Royce, I see there are no magnet spools or brass screws on # 904's flywheel. What keeps the ends of the magnets from moving around?
The early magnetos had the screws and spools in a different location nearer to the center of the flywheel. Here is how it looked when I took it apart:
The center shaft was stamped on manufacture inspection and on assembly. Both were in 1908. The shaft was inspected after machining on 10/28/08/ The transmission assembly was inspected 11/10/ 08:
Royce, my stub shaft also has two dates on it. I have a picture of it somewhere, but both dates are in 1908. I'm not sure about the one being an inspection date and the other being an assembly date, I think the earlier date may have been the initial assembly date and the next date stamped after a repair. There were many changes in those early transmissions and that may have been up dated before installation.
I wonder if 904 started out a 2 lever and was converted prior to sale?
Could be, check the rivets on the brake ratchet. It would have been changed if the car was converted.
