Posted by: Joe TITLE: MISC:   Need Help identifying ~58 Schwinn Frame
I was given a pile of bikes this week, two are late 50~s Schwinn cantilever frames, and all are completely disassembled, and have no chainguards. The one I am guessing to be an early Jaguar or Corvette three speed, but the second one is the one that has me stumped, the closest pics I can find are of a ~56 American, but my serial number is J810xxx, which looks to me to be ~58. The question is what are the choices as far as which model this could have been. The paint is blue and it uses the older Schwinn script on the top tube, and has the checkered pattern decal on the seat post like the ~56 American at:

I have several later Typhoon frames here and the rear of this frame is much wider, and uses a strange stamped steel rear bridge, unlike the half moon type used on the Typhoon. The Rear bridge on this is stamped steel and is raised up above the seat stays, the fenders are off of this, and I~m not sure if the ones I have are even for this bike. Does anyone have any pics of an American or any other models that show the rear brake bridge? How can I tell if this is a middleweight of heavyweight frame? It has loads of clearance with a set of S7 rims and Westwind tires, but a 26x2.125" tire on the S2 rims clears with more than sufficient clearance too. With the 2.125" tires, there us about 3/16" on each side of the tire at the front of the chain stays. The bike in question has a set of what appears to be non schwinn springer forks installed, it appears that the whole pile of bikes has had all sorts of parts swapping going on between the lot of them, but in the group there is Schwinn S2 rims, one set of chrome S7 rims, and two Bendix 2 speed hubs, one New Departure 2 speed hub, and one New Departure model A hub, all of these look to be late 50~s with the exeption of one very early Pre-War balloon tire bike which is definitely not Schwinn, and looks to be an early Roadmaster or similar.

My 56 American had no cantilever brakes, and no sign of there ever being any, on rims, nor fork. it alone has the checkerboard sticker, as they have said. Mine had a 2 speed cable bendix coaster. fukk fenders, looks like mine either had no tank, or it was short lived, again no wear markings from either items.

I was thinking American as well, but there is no sign of it ever having a clamp on front brake, the paint on the forks is untouched. The red, white and blue checker board seat post decal says American though, I suspect that the forks are not original. The forks are identical to those on my ~64 Typhoon, but the rear stays are about a 1/2" wider. The chain stays spread apart sooner than on the Typhoon as well, I doubt that the Typhoon frame would take a 2.125 tire, but there~s plenty of room on this frame.
Was there another model that used the checkered decal? Were there any Americans built without front brakes?
The S-7 rims I found have New Departure hubs. The one decent set of S-2 rims have a New Departure 2 speed, and Schwinn scripted front hub. The bendix hubs were loose in a box, except for one that I cut out of a badly rusted rim that looked to be an S-2. All of the hubs are quite clean, with the exception of the Model A, that one~s a bit pitted, but complete and looks to be in working order.
I do realize that the Model A is much older than the rest of these parts, definitely pre-1930.
The other cantilever frame dates 1953, and has a three speed cable pulley, but the rear brake bidge is broken, and the kickstand tube is cracked loose, so that one will either need some work or end up as scrap. Both are the same width in the rear, and the only actual difference is the type of rear brake bridge.

All the middleweight frames were the same.That flat rear brace is for the caliper brake used on several models. But the american didn~t use the rear caliper brake but had the same bridge .It~s a good bet with the checkered flag decal that it~s an American.A bendix manuel 2 speed came on the American delux in 55&56.Also the american would have had a specal fork clamp on canti brake.
The new departure model A is pre war---most likely pre WW1!!For a wood wheel bike.---sam
