clef after line break in unmetered music

[Steven van Roode]

I encounter the following problem:

In a piece of unmeterd music (like psalm tones or recited text)
I want to decide the place of the line 
breaks. I use

\remove "Time_signature_engraver" 
\remove "Bar_engraver"

to get rid of the time signature and the bars.
Now, a line break with \break results in a new line without a 
clef. How do I get a clef at the beginning of the new line?
