Identified Derailleur related, angle dangulator??? 1964 Schwinn Collegiate derailleur cable bracket adapter!

That's what I was thinking, left side forward facing drop out mount...or right side rear facing drop out. Logic being that the teats have to aim into the drop outs and the cable entry has to be on the outside of the frame. I just don't see it fitting with another claw type hanger for a derailleur. I wish there were a site dedicated to the earlier stay mounted derailleurs.

There's not much info on bolt on style disc brakes either as opposed to frames with dedicated mounts.

That has to be for a rear slotted fork end frame and a stay mounted derailleur.

I believe it is a cable guide bracket for a five speed set up, used on early Collegiates. It mounts in front of the hanger. Here is a picture of the rear Sprint derailleur on my '65 Coppertone Collegiate. I hope this helps.

Nice! It looks like only the 64 men's model Collegiates were pictured with it. I wonder why that was the only derailleur bike that got that with the idler bracket up top...and not the guide at the chain guard bracket? ...were they recycling 3sp frames with the welded on idler bracket?
Looks like your shifter has that hopped up chrome guide too like what I found in the box with it.

Now...I bet there's a longer attach bolt that goes with that too. I'll have to scour the bottom of the bin for those...

If anybody ever needs one, let me know, I found another handfull!

I think it has to do with the shifter being mounted on the top tube of the frame, which sends the cable horizontally to a pulley. From there, it has to follow the seat stay. Of course, this was all redesigned when the stem shifter came out and this bracket became obsolete. You are correct in the fact that a slightly longer bolt is needed. Even though I don't need one, I would like to have one for my stash. PM me with your information.
Thanks, Mike

WOW! Well done! I was wrong thinking it was for the left side.

That cable stop really strikes me as ridiculous. There were other ways to deal with that. Here's Schwinn's first 5 speed model. Another brain fart later on those Collegiates really cracked me up. Not only are these 5 speed chain rings thinner for the 3/32" chain, the dish was reversed from the standard coaster rings. Then on the 1966 Collegiates I believe, they flipped that 5 speed ring with the dish to the inside facing the frame and the stamped part number visible on the outside. Then they had to add a washer behind the chain ring to shim it back outward.

I've not tried to systematically check bottom bracket width and offset, but I'm pretty sure there were changes throughout the years even though the diameter was standard. It would take some special tooling to measure it properly and frame alignment would need to be checked first too, but I'd be willing to bet that some of the early Continental 10 speeds and Corvette 5 speeds had an odd offset to the bottom bracket shell. The 5sp Krates had that washer between the mag sprocket and the BB cone too. There are so many strange little things that go unnoticed about these bikes!

You wanna know what's more ridiculous? I just tried fitting one of these brackets into a derailleur hanger...thought it wasn't going to fit at first, but the teats on the cable bracket just snapped into the reliefs(from manufacturing the teats by pushing material through the hanger) just like a friggin Lego! They're clipped together now.

This is what I've dug out of the bin that's derailleur and 5 speed related so far. Dad probably thought he dug out most of the shiny bits already...
