Problem with remove bar number

[info]

Hello

using version 2.14.1  this is only place I can put the remove bar_number that will allow the piece to compile however I still have bar numbers. So what am I doing wrong?

\score {
\new Staff \melody
\layout {
\context {
\Staff
\remove "Time_signature_engraver"
\remove "Bar_engraver"
\remove "Bar_number_engraver"
}
}

 

Thanks

Jay
