Water well top head drill adapter

A method of drilling, comprising:

• providing a top head drill with an adapter;
• inputting a rotational movement into a top shaft of the adapter;
• driving a gear from the rotational movement that operates a pair of linkage arms;
• and
• providing a reciprocating vertical movement to a plunger from the linkage arms.

A system for imparting a vertical movement to a well drill pipe assembly, comprising:

• a top head drilling unit having a drilling head configured to attach to an adapter;
• the adapter including:
• a top shaft threadably engaged with the drilling head;
• a right angle gear box having an input gear, a first output gear, and a second output gear, the input gear coupled to the top shaft and driven by rotational movement of the drilling head imparted on the top shaft, and the first and second output gears configured to be engaged by the input gear;
• a pair of linkage arms coupled to the first and second output gears by a first output shaft and a second output shaft, the first output shaft and the second output shaft imparting rotation about a horizontal axis to the pair of linkage arms;
• and
• a support extending between the pair of linkage arms and including a plunger for connecting the pipe assembly, the support configured to move vertically with the pair of linkage arms.
