What did Crank-and-Connecting-Rod Blower look like?

A rectangular wooden box with an internal piston. The crank handle is on the outside, with a connecting rod linking the crank to the piston.

How did Crank-and-Connecting-Rod Blower work?

Hand crank → connecting rod → piston reciprocates within the bellows → alternately opens intake/exhaust valves → generates continuous airflow.
