Abstract
Abstract A driving mechanism transforms continuous longitudinal reciprocation of a piston in a chamber into unidirectional rotation. The mechanism utilizes a closed wave-shaped groove defined in either the cylinder or the chamber and adapted to receive guiding members projecting from the other of the piston and the chamber. When the piston is forced to move longitudinally in either direction, the groove slides over the guiding members to force rotation. The apices of the wave-shaped groove are either contoured or provided with a gating structure to assure that the guide members do not backtrack but instead move in one direction through the groove.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A method of converting longitudinal reciprocating motion of a piston in a housing into combined reciprocating and continuous unidirectional rotating motion of a shaft extending externally of said housing, said method comprising the steps of: (a) applying longitudinally alternating force to a first end of said piston to provide continuously repeated longitudinal reciprocating motion of said piston; (b) defining a guide channel in one of said piston and said housing; (c) projecting a guide member into engagement with said guide channel from the other of said piston and said housing; and (d) directing said piston, by means of the engagement between said guide member and said guide channel, to non-intermittently rotate in only one direction in response to said piston continuously reciprocating longitudinally irrespective of longitudinal direction changes of said piston.
Claim 2
Independent Claim
131 words
A method of converting longitudinal reciprocating motion of a piston in a housing into combined reciprocating and continuous unidirectional rotating motion of a shaft extending externally of said housing, said method comprising the steps of: (a) applying longitudinally alternating force to a first end of said piston to provide continuously repeated longitudinal reciprocating motion of said piston; (b) defining a guide channel in one of said piston and said housing; (c) projecting a guide member into engagement with said guide channel from the other of said piston and said housing; and (d) directing said piston, by means of the engagement between said guide member and said guide channel, to non-intermittently rotate in only one direction in response to said piston continuously reciprocating longitudinally irrespective of longitudinal direction changes of said piston.
Claim 3
Dependent Claim
18 words
The method of claim 1 further comprising the step of: (e) securing a working head to said piston.
Claim 4
Dependent Claim
16 words
The method of claim 2 wherein step (e) includes securing a drill bit to said piston.
Claim 5
Dependent Claim
19 words
The method of claim 2 wherein step (a) comprises applying a series of fluid pressure pulses to said piston.
Claim 6
Dependent Claim
29 words
The method of claim 4 further comprising the step of preventing reciprocation of said working head with said piston while permitting rotation of said working head with said piston.
