Abstract
Abstract A transmission control for a motor vehicle includes a valve and a spool mounted in the valve biased to extend therefrom. A spool actuator member controls extension of the spool from the valve. A spool control member is connected to move in response to movement of an operator control. An adjustable engaging member on the spool control member moves a predetermined distance free of forced engagement with the spool actuator. Subsequently the engaging member engages and moves the spool actuating member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A transmission control for a motor vehicle, comprising: a control valve on the vehicle; a spool mounted in the valve; a support member attached to the valve; a spool actuator member pivotally connected to the support member; first resilient means for urging the spool into contact with the spool actuator member; second resilient means for urging the actuator member into contact with the spool in opposition to the first resilient means; an operator control movably mounted on the vehicle; spool control means for movement in response to movement of the operator control a predetermined distance, free of forced engagement with the spool actuator means and subsequently for forcibly engaging and moving the spool actuator means for permitting movement of the spool, said spool control means is positioned between said operator control and said spool actuator member; and means for adjusting the predetermined distance.
Claim 2
Dependent Claim
143 words
A transmission control for a motor vehicle, comprising: a control valve on the vehicle; a spool mounted in the valve; a support member attached to the valve; a spool actuator member pivotally connected to the support member; first resilient means for urging the spool into contact with the spool actuator member; second resilient means for urging the actuator member into contact with the spool in opposition to the first resilient means; an operator control movably mounted on the vehicle; spool control means for movement in response to movement of the operator control a predetermined distance, free of forced engagement with the spool actuator means and subsequently for forcibly engaging and moving the spool actuator means for permitting movement of the spool, said spool control means is positioned between said operator control and said spool actuator member; and means for adjusting the predetermined distance.
Claim 3
Dependent Claim
27 words
The control of claim 1, wherein the spool control means comprises: a control member connected to the operator control and extending therefrom through the spool actuator member.
Claim 4
Dependent Claim
26 words
The control of claim 1, wherein the spool control means comprises: a cable connected to the operator control and extending therefrom through the spool actuator member.
Claim 5
Dependent Claim
26 words
The control of claim 1, wherein the spool control means comprises: a control member pivotally mounted on the vehicle in fixed relationship with the operator control.
Claim 6
Dependent Claim
21 words
The control of claim 1, wherein: the means for adjusting the predetermined distance includes a follower adjustably mounted on the spool.
Claim 7
Dependent Claim
23 words
The control of claim 1, wherein: the means for adjusting the predetermined distance includes a follower adjustably mounted on the spool control means.
Claim 8
Dependent Claim
171 words
A vehicle, comprising: a transmission control including a control valve; a spool biased to extend from the control valve; spool actuator means for controlling extension of the spool from the valve, said spool actuator means including: a support member mounted on the valve and; a spool actuator member pivotally connected to the support member, said spool actuator member being resiliently biased into engagement with the spool to resist pivotal movement; first resilient means for urging the spool into contact with the spool actuator member; second resilient means for urging the actuator member into contact with the spool in opposition to the first resilient means; an operator control; spool control means for movement in response to movement of the operator control a predetermined distance, free of forced engagement with the spool actuator means and subsequently for forcibly engaging and moving the spool actuator means for permitting movement of the spool, said spool control means is positioned between said operator control and said spool actuator member; and means for adjusting the predetermined distance.
Claim 9
Dependent Claim
