Staff Ending

[Joerg Zahn]

Hello, I look for a way to end staff lines by force.

In my example, if i add more patterns, lilypond decides for me where to
begin a new staff line.

Say, i want my staff to only have 4 bars and than a new staff line.
\new Staff does not seem to do the trick.

\version "2.24.4"
\header {
  title = "Untitled"
  composer = "Composer"
}
\layout {
  indent = 0.0
}
pattern_c = {c,8 ^"c" c16 g,8. c8 | }
pattern_g = {g,8 d16 d,8. d8 | }

signature = {
  \clef "bass_8"
  \numericTimeSignature\time 2/4
  \key c \minor
}
\score {
  \new Staff {
    \signature
    \pattern_c 
    \pattern_c
    \pattern_g
    \pattern_g
    \pattern_g
    \pattern_g
    \pattern_c
    \pattern_c
  }
}
