Abstract
Abstract A apparatus for the control of a transmission and throttle of a forklift or the like to provide simultaneous control of a transmission position and the throttle position. The apparatus includes a reciprocally and rotatably moveable control rod and a transmission control lever oppositely reciprocable from a neutral position to forward and reverse displacement positions, coupled to and responsive to the movement of the control rod in first and second translational passageways. A throttle control lever is also coupled to and responsive to the movement of the control rod for controlling the throttle responsive to movement of the control rod in the first and second translational passageways and in a third translational passageway. The third translational passageway is defined by first and second wall members which are substantially parallel. The first and second passageways are formed by the first wall member and a fourth wall member and the second wall member and a third wall member respectively. Forward and reverse footpedals are coupled to the control rod by linkage means whereby actuation of the forward footpedal causes the control rod to move along the first passageway thereby opening the throttle and positioning the transmission in the forward position, actuation of the reverse footpedal causes the control rod to move along the second passageway thereby opening the throttle and positioning the transmission in the reverse position, actuation of both the forward and reverse footpedals causes the control rod to open the throttle while leaving the transmission in the neutral position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A transmission-throttle control apparatus comprising: a swingable and rotatably moveable control rod; a transmission control lever oppositely reciprocable from a neutral position to forward and reverse displacement positions coupled and responsive to the movement of said control rod in first and second translational passageways; a throttle control lever oppositely reciprocalable to open and close a throttle responsive to the movement of said control rod in said first and second translational passageways and in a third translational passageway; said third translational passageway being defined by first and second wall members, said first passageway being defined by said first wall member and a fourth wall member, and said second passageway being defined by said second wall member and a third wall member, said first, second and third passageway being adjacent said control rod and adopted to allow said control rod to traverse along the path of said passageways; and linkage means coupling first and second control means to said control rod whereby actuation of said first control means causes said control rod to move along said first passsageway, actuation of said second control means causes said control rod to move along said second passageway and activation of both said first and second control means causes said control rod to move along third passageway.
Claim 2
Dependent Claim
211 words
A transmission-throttle control apparatus comprising: a swingable and rotatably moveable control rod; a transmission control lever oppositely reciprocable from a neutral position to forward and reverse displacement positions coupled and responsive to the movement of said control rod in first and second translational passageways; a throttle control lever oppositely reciprocalable to open and close a throttle responsive to the movement of said control rod in said first and second translational passageways and in a third translational passageway; said third translational passageway being defined by first and second wall members, said first passageway being defined by said first wall member and a fourth wall member, and said second passageway being defined by said second wall member and a third wall member, said first, second and third passageway being adjacent said control rod and adopted to allow said control rod to traverse along the path of said passageways; and linkage means coupling first and second control means to said control rod whereby actuation of said first control means causes said control rod to move along said first passsageway, actuation of said second control means causes said control rod to move along said second passageway and activation of both said first and second control means causes said control rod to move along third passageway.
Claim 3
Dependent Claim
32 words
The transmission-throttle control apparatus claimed in claim 1 wherein said first control means is further defined as a forward footpedal and said second control means is further defined as a reverse footpedal.
Claim 4
Dependent Claim
27 words
The transmission-throttle control apparatus claimed in claim 1 wherein said control rod is provided with a roller member adopted to roll along said walls defining said passageways.
Claim 5
Dependent Claim
18 words
The transmission-throttle control apparatus claimed in claim 1 wherein said first and second wall members are substantially parallel.
Claim 6
Dependent Claim
34 words
The transmission-throttle control apparatus claimed in claim 4 wherein said third and fourth wall members are positioned between 30° and 45° on either side of the centerline of said first and second wall members.
Claim 7
Dependent Claim
220 words
A transmission-throttle control apparatus for a forklift comprising: a swingable and rotatably moveable control rod provided with a roller member; a transmission control lever oppositely reciprocable from a neutral position to forward and reverse displacement positions coupled and responsive to the movement of said control rod in first and second translational passageways; a throttle control lever oppositely reciprocable to open and close a throttle responsive to the movement of said control rod in said first and second translational passageways and in a third translational passageway; said third translational passageway being defined by first and second substantially parallel wall members, said first passageway being defined by said first wall member and a fourth wall member, and said second passageway being defined by said second wall member and a third wall member, said first, second and third passageways being adjacent said control rod roller member and adopted to allow said control rod roller member to traverse said passageways; and linkage means coupling a forward footpedal and a reverse footpedal to said control rod whereby actuation of said forward footpedal causes said control rod to move along said first passageway, actuation of said reverse footpedal causes said control rod to move along said second passageway and activation of both forward and reverse footpedals causes said control rod to move along said third passageway.
Claim 8
Dependent Claim
