Abstract
Abstract Disclosed is an apparatus for operating two control devices with a single hand operated lever. The hand lever is pivotally mounted for movement to forward and reverse positions from a neutral position to operate one control device directly. During a portion of its pivotal movement on either side of neutral it does not influence the second control device, but upon further displacement from neutral it engages a second lever pivotally mounted in coplanar relation with the hand lever to displace the second lever from its neutral position. The second lever is resiliently biased toward its neutral position so that it returns to it as the hand lever is moved toward its neutral position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
76 words
Control apparatus comprising: a. housing means; b. first and second lever means mounted for substantially coplanar oscillating movement within said housing about a neutral position; c. means for interconnecting said first lever means and said second lever means only during the portion of the travel of said first lever means remote from its neutral position; and d. means for maintaining said second lever means in a predetermined position when not interconnected with said first lever means.
Claim 2
Dependent Claim
76 words
Control apparatus comprising: a. housing means; b. first and second lever means mounted for substantially coplanar oscillating movement within said housing about a neutral position; c. means for interconnecting said first lever means and said second lever means only during the portion of the travel of said first lever means remote from its neutral position; and d. means for maintaining said second lever means in a predetermined position when not interconnected with said first lever means.
Claim 3
Dependent Claim
40 words
The apparatus defined in claim 1 wherein said second lever means includes opposed tab portions at one end thereof and disposed on opposite sides of said first lever means, and said first lever means includes means for engaging said tabs.
Claim 4
Dependent Claim
32 words
The apparatus defined in claim 1 including resilient means for urging said second lever toward a position approximately equidistant from the opposite limits of travel of said second lever within said housing.
Claim 5
Dependent Claim
194 words
Control apparatus comprising: a. housing means; b. first and second lever means mounted for substantially coplanar oscillating movement within said housing; c. means for interconnecting said first lever means and said second lever means during a portion of the travel of said first lever means; and d. resilient means for urging said second lever means toward a position approximately equidistant from the opposite limits of travel of said second lever means within said housing comprising: i. first and second elongated members mounted for oscillating movement with said second lever means, said first elongated member being adapted to follow said second lever means as said second lever means is moved in a first direction from said position equidistant from the opposite limits of travel thereof; and said second elongated member being adapted to follow said second lever means as said second lever means is moved in the opposite direction from said position equidistant from the opposite limits of travel thereof; and ii. first and second springs secured between said first and second elongated members and said housing, respectively, for urging said second lever means toward said position equidistant from the opposite limits of travel thereof.
Claim 6
Dependent Claim
194 words
Control apparatus comprising: a. housing means; b. first and second lever means mounted for substantially coplanar oscillating movement within said housing; c. means for interconnecting said first lever means and said second lever means during a portion of the travel of said first lever means; and d. resilient means for urging said second lever means toward a position approximately equidistant from the opposite limits of travel of said second lever means within said housing comprising: i. first and second elongated members mounted for oscillating movement with said second lever means, said first elongated member being adapted to follow said second lever means as said second lever means is moved in a first direction from said position equidistant from the opposite limits of travel thereof; and said second elongated member being adapted to follow said second lever means as said second lever means is moved in the opposite direction from said position equidistant from the opposite limits of travel thereof; and ii. first and second springs secured between said first and second elongated members and said housing, respectively, for urging said second lever means toward said position equidistant from the opposite limits of travel thereof.
Claim 7
Dependent Claim
28 words
The apparatus defined in claim 4 and further including stop means associated with each of said first and second elongated members for limiting movement of said elongated members.
