How to connect this into lan??

Hello,
Okay, so here is a deal i got three PCs that i need to connect into lan, but two routers. Two PCs are connected into R1 and the R1 is connected into R2, 3rd PC is connected into R2 and R2 is connected to internet.
Internet works on all three PCs but i cant get lan to work. Can anyone help? I will try to make a brief sketch of the connections.
