Abstract
Abstract Disclosed herein is a control mechanism including a first manual lever adapted to select one mode of operation and a second manual lever adapted to select another mode of operation and a linkage connecting the two selector levers to prevent simultaneous movement of the two levers. The interconnecting linkage also provides automatic cancellation of the mode selected by the second lever when the first lever is actuated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A control mechanism comprising first selector means for selecting one mode of operation including guide standard means, first handle means slidably mounted on said guide standard means and being linearly moveable to first and second positions, first actuator means for providing one output from the control mechanism, and linkage means operatively connected between said handle means and said first actuator means for converting linear motion of said first handle means to rotary motion of said first actuator means; second selector means for selecting another mode of operation including second actuator means for providing another output, and second handle means mounted on said second actuator means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said second selector means and said linkage means, and cancelling cam means coacting with said cancelling link means and said linkage means for locating said second selector means in the second position when said first selector means is moved linearly from said first to said second position.
Claim 2
Dependent Claim
171 words
A control mechanism comprising first selector means for selecting one mode of operation including guide standard means, first handle means slidably mounted on said guide standard means and being linearly moveable to first and second positions, first actuator means for providing one output from the control mechanism, and linkage means operatively connected between said handle means and said first actuator means for converting linear motion of said first handle means to rotary motion of said first actuator means; second selector means for selecting another mode of operation including second actuator means for providing another output, and second handle means mounted on said second actuator means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said second selector means and said linkage means, and cancelling cam means coacting with said cancelling link means and said linkage means for locating said second selector means in the second position when said first selector means is moved linearly from said first to said second position.
Claim 3
Dependent Claim
156 words
A transmission shift control mechanism comprising forward-drive-selecting means including guide standard means, forward selector means slidably mounted on said guide standard means and being linearly moveable to first and second positions, forward electric switch means, and forward linkage means operatively connected between said forward selector means and said forward electric switch means for converting linear motion of said forward selector means to rotary motion of said forward electric switch means; reverse-drive-selecting means including reverse electric switch means, and reverse selector means mounted on said reverse electric switch means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said reverse selector means and said forward linkage means, and cancelling cam means coacting with said cancelling link means and said forward linkage means for locating said reverse selector means in the second position when said forward selector means is moved linearly from said first to said second position.
Claim 4
Dependent Claim
156 words
A transmission shift control mechanism comprising forward-drive-selecting means including guide standard means, forward selector means slidably mounted on said guide standard means and being linearly moveable to first and second positions, forward electric switch means, and forward linkage means operatively connected between said forward selector means and said forward electric switch means for converting linear motion of said forward selector means to rotary motion of said forward electric switch means; reverse-drive-selecting means including reverse electric switch means, and reverse selector means mounted on said reverse electric switch means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said reverse selector means and said forward linkage means, and cancelling cam means coacting with said cancelling link means and said forward linkage means for locating said reverse selector means in the second position when said forward selector means is moved linearly from said first to said second position.
Claim 5
Dependent Claim
195 words
A transmission shift control mechanism comprising forward-drive-selecting means including guide standard means, forward selector means slidably mounted on said guide standard means and being linearly moveable to first and second positions, forward electric switch means and forward linkage means operatively connected between said forward selector means and said forward electric switch means for converting linear motion of said forward selector means to rotary motion of said forward electric switch means; reverse-drive-selecting means including reverse electric switch means, and reverse selector means mounted on said reverse electric switch means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said reverse selector means and said forward linkage means, cancelling guide means coacting with said cancelling link means and said forward linkage means having cam means for moving said reverse selector means from said first or third position to said second position when said forward selector means is moved linearly from said first to said second position, and slot means for positioning said cancelling link means to prevent pivoting of said reverse selector means from said second position when said forward selector means is in the second position.
Claim 6
Dependent Claim
195 words
A transmission shift control mechanism comprising forward-drive-selecting means including guide standard means, forward selector means slidably mounted on said guide standard means and being linearly moveable to first and second positions, forward electric switch means and forward linkage means operatively connected between said forward selector means and said forward electric switch means for converting linear motion of said forward selector means to rotary motion of said forward electric switch means; reverse-drive-selecting means including reverse electric switch means, and reverse selector means mounted on said reverse electric switch means and being pivotable to first, second and third positions; and cancelling means including cancelling link means for operatively connecting said reverse selector means and said forward linkage means, cancelling guide means coacting with said cancelling link means and said forward linkage means having cam means for moving said reverse selector means from said first or third position to said second position when said forward selector means is moved linearly from said first to said second position, and slot means for positioning said cancelling link means to prevent pivoting of said reverse selector means from said second position when said forward selector means is in the second position.
