Cleaning out the shop found an odd coil box it has a kw switch 1913-14 std kw points the coils are bolted in and are smaller than most. The wire connections come out the bottom, we,re going to sell it but we need to know what it is? any thoughts?
Are those plastic case coils or do they just look like plastic case coils.
the top is thin plastic or bak-o-lite the rest is wood
This coil box has been kicking around our place since the mid 1960s but Dad has never seen another.
I have some coils with pins coming out of the bottom something like that too.
It would be good to know what they are for.
I think those KW boxes and coils were available in late 1912 model year and through perhaps spring of 1913, near the end of 1913 model year, when the metal KW style coil box replaced all the earlier types.
If you have the lid for it, then you have a very desirable setup for someone doing a concours restoration of a late '12. For a driver, I would use a reproduction wood box that accepts the 1913 and later KW coils. Those coils are hard to find and expensive to buy when they are found.
I could be wrong but I thought the 13 style KW boxes had terminals out the back like later boxes. The only style that had terminals out the bottom were the carryovers from NRS production and used in small quantity on the 09 Model Ts. I agree the style of the switch dates it to 1913, but I think it is a non Ford application.
Richard, Ahh good call. I agree with you - the switch is like the Ford version, and the coils look similar, but the lack of terminals on the back makes it non Ford.
If anyone would know about that box, it would be RV. I have KW's on both of my '13s, and have never seen this one. I agree with Richard too, that this was a non-Ford application.
Let's see the inside of the box.
Are the coils dimensionally the same as the later 1914-1927 coils?
: ^ )
The coils are small like the heize coils
I saw one of those coil boxes at an auction of pre T cars. According to a knowledgeable friend of mine that coil was a "replacement" coil box for the NRS series cars and came out well after the production of those cars had ceased. It is a 1913 era product but sold to pre T Ford customers mainly and other 4 cylinder cars such as Knox or other cars during the era. The Connecticut Electric coil box on a 1908 Knox I helped restore had 4 brand new looking but totally dead coils with open HV secondaries. I spotted one on Ebay and bought it too but it also was open. KW coil box would have worked perfectly on this Knox since like most cars other than the Ford T - the spark plug wires were routed out the bottom and then forward.
That is my take on it.
I believe John is correct. The holes in the top left hand edge of the box all correspond with thumb nuts that can be seen on the LH bridge studs. These are the timer wire holes. The hot wire from the battery goes through the selective switch and is picked by the coils through the brass buss bar that can be seen inside the right hand side of the box. The hookup pattern is similar to original Splitdorf coilboxes.
