Abstract
Abstract A control assembly for mechanically transmitting a signal from a sending unit to a receiving element is provided which enables the receiving unit to respond to shifting of the sending unit for reducing perceived hysteresis losses during shifting. The sending unit includes a wear plate defining a series of positions thereon for engagement by a shiftable control arm. The control arm is connected by a cable to the receiving element which includes an indicator on a mounting member. During initial shifting of the control arm, the wear plate, which is pivotally mounted, is limited in its travel by one or more prongs extending through the wear plate. Further shifting of the control arm moves the cable so that the indicator moves responsively thereto.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
A control assembly comprising: a sending unit including a control member for shifting responsively to an input signal; a remotely located receiving element; and means for mechanically connecting said control member to said receiving element for moving said receiving element from a first location to a second location responsive to shifting of said control member, said sending unit further comprising a mounting member and a wear plate adjacent to said control member, said wear plate being positioned intermediate said mounting member and said control member and presenting structure defining a first position and a second position thereon, said control member being releasably engageable with said structure defining said first position and said second position, said sending unit including means for enabling limited responsive shifting of said wear plate relative to said mounting member a predetermined portion of the travel of said control member between said first location and said second location during shifting of said control member.
Claim 2
Dependent Claim
157 words
A control assembly comprising: a sending unit including a control member for shifting responsively to an input signal; a remotely located receiving element; and means for mechanically connecting said control member to said receiving element for moving said receiving element from a first location to a second location responsive to shifting of said control member, said sending unit further comprising a mounting member and a wear plate adjacent to said control member, said wear plate being positioned intermediate said mounting member and said control member and presenting structure defining a first position and a second position thereon, said control member being releasably engageable with said structure defining said first position and said second position, said sending unit including means for enabling limited responsive shifting of said wear plate relative to said mounting member a predetermined portion of the travel of said control member between said first location and said second location during shifting of said control member.
Claim 3
Dependent Claim
25 words
A control assembly as set forth in claim 1, said control member being pivotally mounted on said mounting member for pivoting about a first axis.
Claim 4
Dependent Claim
23 words
A control assembly as set forth in claim 2, said wear plate being pivotally mounted on said mounting member about said first axis.
Claim 5
Dependent Claim
16 words
A control assembly as set forth in claim 3, said mechanical connecting means including cable means.
Claim 6
Dependent Claim
31 words
A control assembly as set forth in claim 4, said cable means including an outer sheat and an inner cable movably element operably connecting said control member to said receiving element.
Claim 7
Dependent Claim
31 words
A control assembly as set forth in claim 5, said receiving element being carried by a receiving element mount, said mounting member being stationary with respect to said receiving element mount.
Claim 8
Dependent Claim
38 words
A control assembly as set forth in claim 2, said control member presenting a projection selectively engageable with said wear plate for producing pivoting of said wear plate during a limited length of travel of said control member.
Claim 9
Dependent Claim
18 words
A control assembly as set forth in claim 7, including structure interconnecting said wear plate and said mount.
Claim 10
Dependent Claim
144 words
In a control assembly for mechanically transmitting a control signal from a sending unit to a receiving element, said sending unit having a mounting member and a shiftable control member operatively connected by motive means to said receiving element for responsive movement of said receiving element during shifting of said control member, the improvement comprising a wear plate presenting structure defining a first position, a second position and a third position, said second position being intermediate said first and third positions, and means associated with said wear plate for enabling limited pivoting of said wear plate relative to said mounting member during shifting of said control member to produce substantially consistent location of said receiving element in said second position during shifting of said control member both from said first position to said second position and from said third position to said second position.
Claim 11
Dependent Claim
144 words
In a control assembly for mechanically transmitting a control signal from a sending unit to a receiving element, said sending unit having a mounting member and a shiftable control member operatively connected by motive means to said receiving element for responsive movement of said receiving element during shifting of said control member, the improvement comprising a wear plate presenting structure defining a first position, a second position and a third position, said second position being intermediate said first and third positions, and means associated with said wear plate for enabling limited pivoting of said wear plate relative to said mounting member during shifting of said control member to produce substantially consistent location of said receiving element in said second position during shifting of said control member both from said first position to said second position and from said third position to said second position.
Claim 12
Dependent Claim
30 words
A control assembly as set forth in claim 9, said sending unit including a mounting member, said wear plate and said control member being pivotally mounted on said mounting member.
Claim 13
Dependent Claim
33 words
A control assembly as set forth in claim 10, including means operably connecting said wear plate and said mounting member for limiting the pivoting of said wear plate relative to said mounting member.
Claim 14
Dependent Claim
40 words
A control assembly as set forth in claim 10, said pivot limiting means comprising at least one abutment member extending from said wear plate into structure defining an aperture in said mounting member, said abutment being movable within said aperture.
