suppress time signatures?

[Gerard McConnell]

Hello,

I would like to use Lilypond to write sight-reading exercises for my piano students.   The exercises are generally 8 bars long, on a single system, with a final barline at the end of each line.   Each new line requires a time signature.

How do I suppress the time signature which is inserted automatically at the end of a line?   

 

Here's a snippet of my input:

    \time 2/4
    c2 d c4 d c2 d d4 c d2 c \bar "|."
    \break

 

    \time 2/4
    d2 c  etc.  \bar "|."
    \break

 

Thanks for any help,

Gerard
