Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
A transmission shifting mechanism for shifting a transmission comprising, a transmission housing, a shaft having a crank arm reciprocally and pivotally mounted in said housing, shift rails slidably mounted for selective engagement by said crank arm responsive to reciprocal movement of said shaft, a shift lever mounted on said shaft for selectively reciprocating and pivoting said shaft to shift said vehicle transmission, a side cover on said transmission for supporting said shifting mechanism and said shift rails to allow complete removal of the shifting mechanism when said cover is removed from the transmission.
Claim 2
Dependent Claim
93 words
A transmission shifting mechanism for shifting a transmission comprising, a transmission housing, a shaft having a crank arm reciprocally and pivotally mounted in said housing, shift rails slidably mounted for selective engagement by said crank arm responsive to reciprocal movement of said shaft, a shift lever mounted on said shaft for selectively reciprocating and pivoting said shaft to shift said vehicle transmission, a side cover on said transmission for supporting said shifting mechanism and said shift rails to allow complete removal of the shifting mechanism when said cover is removed from the transmission.
Claim 3
Dependent Claim
29 words
A transmission shift mechanism for shifting a transmission, as set forth in claim 1, including a cradle mounted on said shaft, means pivotally connecting said lever with said cradle.
Claim 4
Dependent Claim
26 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including shifting forks mounted on said shift rails for shifting said transmission.
Claim 5
Dependent Claim
24 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including means supporting said shift rails normal to said shaft.
Claim 6
Dependent Claim
31 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including means mounting said rails normal to said shaft whereby reciprocating said shaft selectively engages said rails.
Claim 7
Dependent Claim
30 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including a cradle fixedly connected to said shaft, means pivotally connecting said lever to said cradle.
Claim 8
Dependent Claim
31 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including means pivotally connecting said lever on said shaft in a common plane with said crank arm.
Claim 9
Dependent Claim
60 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including a cradle mounted on said shaft extending downwardly from said shaft, means pivotally connecting said lever to said cradle, means pivotally connecting said shaft to said lever, said lever thereby reciprocating said shaft through a transverse movement and pivoting said shaft by a longitudinal movement.
Claim 10
Dependent Claim
69 words
A transmission shift mechanism for shifting a transmission as set forth in claim 1 including means supporting said shaft transversely on said transmission, means supporting shift rails longitudinally on supporting structure on said cover, shift forks connected to said shift rails for shifting gears in said transmission, a cradle mounted on the end of said shaft pivotally supporting said shift lever to provide means for shifting said shifting mechanism.
Claim 11
Dependent Claim
49 words
A transmission shifting mechanism for shifting a transmission as set forth in claim 1 including at least two shift rails, detent means defining shift and neutral positions of each of said shift rails, interlock means between said shift rails permitting only one rail to be shifted at one time.
