Control device having locking selector means
First Claim
1. In a control device having support means, a first selector member rotatably carried by said support means, a second selector member rotatably carried by said support means and being axially movable relative to said support means and said first selector member, said selector members having means coupling the same together to cause said first selector member to rotate in unison with said second selector member when said second selector member is rotated, and spring means disposed between said selector members to tend to maintain said second selector member axially away from said first selector member, the improvement wherein said spring means comprises a pair of dished spring members disposed between and respectively engaging said selector members, said means coupling said selector members together comprising spline means disposed outboard of said dished spring members and surrounding the same.

Abstract
A control device having a support and a first selector member rotatably carried by the support. A second selector member is rotatably carried by the support and is axially movable relative to the support and the first selector member. The selector members are coupled together in a manner to cause the first selector member to rotate in unison with the second selector member when the second selector member is rotated. A pair of spaced spring members are disposed between and respectively engage the selector members to tend to maintain the second selector member axially away from the first selector member. The first selector member has a cylindrical part extending therefrom and the second selector member has a C-shaped shaft rotatably disposed against the cylindrical part of the first selector member. A tang extends radially outwardly from the second selector member and is received between two spaced apart abutments on a surface of the support when the second selector member is in one rotational position thereof so that the second selector member is locked in that one rotational position until the second selector member is axially moved toward the first selector member a certain amount.
