[GreenKeys] M-15... Auto Line Feed After every printed character

[hwhall@aol.com]

Took some pics of the LF Push Bar, LF Push Bar Spring & LF Bail. The spring never showed in the usual drawings because it would've been behind the LF Bail, I guess. It's indicated in the attached photo by a round green dot.

When the Vanes encode for a LF, the LF Function Lever can rotate forward (toward typist) on a pivot near its lower-front end. That causes the LF Function Lever Extenstion (a sort of tail piece) to rotate upwards, lifting the LF Push Bar so that the step on its upper edge can be caught by the Function Bail, initiating the LF movements. For some reason, TBD by inspection, the LF Push Bar is sitting too high when characters are being printed - the same bail rotation that moves the typing bars is shoving the LF Push Bar when it shouldn't be.

I also have a short video of the LF Function Lever rotating & operating the LF Push Bar if necessary.

I can not find the 'Line Feed Push Bar Spring' anywhere. Not on the drawing or unit. Where is it located please?

The same thing happened to me in the early days of my M15 year ago and I for the life of me could not remember what the solution was… it ended up being this!  Some of those springs are so small — if they happen to pop off while working on it, you’ll never know.  I ended up finding that spring on the floor, but prior to that, the same thing inflicted my 15/19 for a time (LF after each character).
