Abstract
Abstract A multiple speed gear shift having a shifting handle that is movable laterally so its end part can engage in a recess in one of closely spaced parallel slide members. Interconnections are provided between the slide members and shift levers on a transmission. Pivoted apertured adaptor levers are provided as a part of the shift unit or as a separate accessory. The slide members attach by links to apertures in the adaptor levers and straight connecting links connect between other apertures in the adaptor levers and the shift levers on the transmission.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A multiple speed shift mechanism comprising: a shifting handle; a plurality of parallel slide members; and means comprising a U-shaped member in which said members slide directly adjacent each other, each of said slide members having a recess in it, said recesses being alignable with each other, the shifting handle having a rigid end part engageable in a recess of a slide and the handle being movable to move a slide member along the slide means, said shifing handle having mounting means whereby its said end part can be moved laterally with respect to the slide members so as to engage in the recess in an individual slide member, said shift lever having a part that is pivotally mounted, said lever being movable about the pivot axis for movement of individual slide members, and means whereby the shift lever has limited freedom of movement in the direction of the axis of the pivotal mounting for purposes of moving its end part into a recess in an individual slide member.
Claim 2
Dependent Claim
169 words
A multiple speed shift mechanism comprising: a shifting handle; a plurality of parallel slide members; and means comprising a U-shaped member in which said members slide directly adjacent each other, each of said slide members having a recess in it, said recesses being alignable with each other, the shifting handle having a rigid end part engageable in a recess of a slide and the handle being movable to move a slide member along the slide means, said shifing handle having mounting means whereby its said end part can be moved laterally with respect to the slide members so as to engage in the recess in an individual slide member, said shift lever having a part that is pivotally mounted, said lever being movable about the pivot axis for movement of individual slide members, and means whereby the shift lever has limited freedom of movement in the direction of the axis of the pivotal mounting for purposes of moving its end part into a recess in an individual slide member.
Claim 3
Dependent Claim
171 words
A multiple speed shift mechanism comprising: a shifting handle; a plurality of parallel slide members; and means comprising a U-shaped member in which said members slide directly adjacent each other, each of said slide members having a recess in it, said recesses being alignable with each other, the shifting handle having a rigid end part engageable in a recess of a slide and the handle being movable to move a slide member along the slide means, said shifting handle having mounting means whereby its said end part can be moved laterally with respect to the slide members so as to engage in the recess in an individual slide member, said slide members being closely juxtaposed side by side in the slide means, said shifting handle being mounted on a shaft extending between the sides of the U-shaped member to pivotally rotate thereabout, and the shift handle being mounted to provide for limited lateral movement whereby its end part can be moved into the recess of one or another of the slides.
Claim 4
Dependent Claim
171 words
A multiple speed shift mechanism comprising: a shifting handle; a plurality of parallel slide members; and means comprising a U-shaped member in which said members slide directly adjacent each other, each of said slide members having a recess in it, said recesses being alignable with each other, the shifting handle having a rigid end part engageable in a recess of a slide and the handle being movable to move a slide member along the slide means, said shifting handle having mounting means whereby its said end part can be moved laterally with respect to the slide members so as to engage in the recess in an individual slide member, said slide members being closely juxtaposed side by side in the slide means, said shifting handle being mounted on a shaft extending between the sides of the U-shaped member to pivotally rotate thereabout, and the shift handle being mounted to provide for limited lateral movement whereby its end part can be moved into the recess of one or another of the slides.
Claim 5
Dependent Claim
26 words
A shifting mechanism as in claim 1, including spring biasing means normally biasing the shift lever into engagement with a recess in one of the slides.
Claim 6
Dependent Claim
36 words
A shift mechanism as in claim 2, wherein the shift lever has a hole in it through which the said shaft passes, the hole being of a size to allow lateral tilting of the shift lever.
