Hi,

I would suggest to never touch the transposition outside of the score. 
Then use \transpose to transpose each instrument’s own music and 
\transposition to adjust the quoted music:

%%%%%%%%

\version "2.18.2"

trumpetNotes = \relative c'' {
  c4 c c c
}
\addQuote "trumpet" \trumpetNotes

clarinetNotes = \relative c'' {
  g4
  \quoteDuring #"trumpet" { s }
  g g |
}

altoSaxNotes = \clarinetNotes

<<
  \new Staff \with {
    instrumentName = "trumpet"
  } \transpose bes c' {
    \transposition bes
    \trumpetNotes
  }
  \new Staff \with {
    instrumentName = "clarinet"
  } \transpose bes c' {
    \transposition bes
    \clarinetNotes
  }
  \new Staff \with {
    instrumentName = "alto sax"
  } \transpose ees c' {
    \transposition ees
    \altoSaxNotes
  }

Three off-topic comments:

1. You used bar checks where no bar line should be. Are you sure you’ve 
understood them correctly?

2. Trumpets transpose a second down, not a seventh up; alto saxophones 
transpose a sixth down, not a third up. You need to make sure you have 
correct octave marks when using \transpose and \transposition (the 
latter always is relative to c').

3. You can leave out the # (and even the "" if it’s no problem for your 
syntax hilighting) in \quoteDuring #"trumpet" at least in version 2.19; 
but I think that this is already possible in 2.18 and perhaps earlier 
versions.
