Abstract
A shifting mechanism including a shifting lever for moving two control elements is disclosed herein. The control elements and shifting lever are interconnected in such a fashion that one of the control elements can be moved to a plurality of positions while the other control element remains in any one of a plurality of positions.
Claims9
A shifting mechanism including a control lever rotated on a fixed axis adjacent a control member having a recess receiving a portion of said lever so that movement of said control lever will move said control member to a plurality of distinct positions, said lever being pivoted between first and second positions about a second axis perpendicular to said fixed axis, a control element pivoted about a third axis spaced from said second axis, and cooperating means between said control lever and said control element for moving said control element between positions in response to pivotal movement of said control lever between said positions, said cooperating means accommodating rotational movement of said lever about said fixed axis in any position for said control element, said lever being pivotable about said second axis between said first and second positions at each of said distinct positions of said control member so that said control element can be moved between positions of any of said distinct positions of said control member.
A shifting mechanism including a control lever for shifting first and second control elements that are pivoted about first and second fixed axes angularly related to each other, said lever being rotated about said first axis and engaging said first element for rotating said first element between a plurality of distinct positions, said lever being pivotable along said first axis, an elongated member pivoted about a third axis between first and second positions in response to pivotal movement of said control lever and having cooperating means for moving said second element, said elongated member accommodating rotational movement of said control lever in either of said first and second positions so that said first control element can be rotated to a plurality of locations while said second element is in any position.
A shifting mechanism including a control lever rotated on a fixed axis adjacent a control member having a recess receiving a portion of said lever so that movement of said control lever will move said control member between a plurality of locations, said lever being pivoted between a plurality of positions about a second axis perpendicular to said fixed axis, a control element pivoted about a third axis spaced from said second axis, cooperating means between said control lever and said control element for moving said control element between positions in response to pivotal movement of said control lever between said positions, said cooperating means accommodating rotational movement of said lever about said fixed axis in any position for said control element and a quadrant spaced from said fixed axis and defining a plurality of elongated parallel recesses equal in number to said positions of said control lever with said control lever having a projection located in the respective recesses for the respective positions of said lever, said cooperating means including a U-shaped member having opposed legs pivoted about an axis between said fixed axis and said quadrant, one of said legs cooperating with said control element, said lever having an arm secured thereto and extending between said legs so that pivotal movement of said lever between said positions will pivot said U-shaped member and said control element between positions.
