Simple LED Counter

I'm making a simple counter with an LED display for a project at school. I have two LED displays, two 7447 IC's, two 74160 IC's, and a 555 timer. But I'm having problems getting the counter to carry over between the two digit display.

I'm currently only able to count to 9.

Any suggestions?

74160 is a synchronous counter, it uses a ripple carry in stead of normal carry.
