Speed game up

[Robert G]

I am a LL ump, & I have been reading the Federation rule book(good summer reading)It says the offensive team is limited to 3 visits by the coach during a 7 inning game.
In LL & OBR I don't know of such a rule. But last month it seemed like every other pitch the 3rd base coach would call time & talk to B1. Is there anything or rule I could say to help speed the game along? It was not covered during our pre-game meeting. Any thoughts?

Happy 4th.
