Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 145 words
A multi-power ratchet wrench comprising a main housing and handle, a driven shaft mounted in said housing for rotation, an external drive member on said shaft adapted to removably receive a socket, a first pinion fixed on said shaft within said housing, a second drive shaft in said housing parallel to said first drive shaft, a driving pinion in said housing on said second drive shaft engaging said first pinion, said first and second pinion being arranged to provide the desired amount of multiplication of power to the first from the second, a second driven pinion on said second shaft, a second handle journaled for rotation about said second shaft, and ratchet drive means on said second handle selectively engaging the second driven pinion to rotate the second shaft and thereby the first shaft when the second handle is moved relative to the first handle.
Claim 2
Dependent Claim 145 words
A multi-power ratchet wrench comprising a main housing and handle, a driven shaft mounted in said housing for rotation, an external drive member on said shaft adapted to removably receive a socket, a first pinion fixed on said shaft within said housing, a second drive shaft in said housing parallel to said first drive shaft, a driving pinion in said housing on said second drive shaft engaging said first pinion, said first and second pinion being arranged to provide the desired amount of multiplication of power to the first from the second, a second driven pinion on said second shaft, a second handle journaled for rotation about said second shaft, and ratchet drive means on said second handle selectively engaging the second driven pinion to rotate the second shaft and thereby the first shaft when the second handle is moved relative to the first handle.
Claim 3
Dependent Claim 35 words
A multi-power ratchet wrench as claimed in claim 1 wherein the second driven pinion is surrounded by a second housing on the second handle, said second housing being journaled on the first housing for rotation.
Claim 4
Dependent Claim 26 words
A multi-power ratchet wrench as claimed in claim 2 wherein the first housing has an upstanding collar on which the second housing is journaled for rotation.
Claim 5
Dependent Claim 32 words
A multi-power ratchet wrench as claimed in claim 1 wherein means are provided on the second housing for shifting said ratchet means selectively to control direction of rotation of the second pinion.
Claim 6
Dependent Claim 17 words
A multi-power wrench as claimed in claim 1 wherein the two handles are of substantially equal length.
