Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
197 words
A directional control lever and horn actuating arrangement comprising: a frame; a directional control lever assembly having a control lever arranged on a central axis and being pivotally supported on said frame for movement about a pivot axis into a plurality of operating positions; an electrical circuit including in serially communicating order a first contact member, a source of electricity connected to said first contact member, a horn connected to said source of electricity and a second contact member connected to said horn and being spaced from said first contact member and providing an electrically open circuit condition, said circuit being connected to said frame, one of said contact members being arcuately profiled and defining a substantially fixed distance from said pivot axis; and manually actuated means including a movable element supported by said directional control lever assembly and selectively movable along said central axis between first and second positions for contacting said arcuately profiled contact member, electrically connecting said first and second contact members and selectively actuating said horn, said first position of said movable element maintaining a preselected distance from said arcuately profiled contact member when said control lever is rotated about said pivot axis.
Claim 2
Dependent Claim
197 words
A directional control lever and horn actuating arrangement comprising: a frame; a directional control lever assembly having a control lever arranged on a central axis and being pivotally supported on said frame for movement about a pivot axis into a plurality of operating positions; an electrical circuit including in serially communicating order a first contact member, a source of electricity connected to said first contact member, a horn connected to said source of electricity and a second contact member connected to said horn and being spaced from said first contact member and providing an electrically open circuit condition, said circuit being connected to said frame, one of said contact members being arcuately profiled and defining a substantially fixed distance from said pivot axis; and manually actuated means including a movable element supported by said directional control lever assembly and selectively movable along said central axis between first and second positions for contacting said arcuately profiled contact member, electrically connecting said first and second contact members and selectively actuating said horn, said first position of said movable element maintaining a preselected distance from said arcuately profiled contact member when said control lever is rotated about said pivot axis.
Claim 3
Dependent Claim
45 words
The directional control lever and horn actuating arrangement of claim 1 wherein said movable element directly biases said arcuately profiled contact member into electrical engagement with the other one of said contact members in said second position of the movable element to operate said horn.
Claim 4
Dependent Claim
42 words
The directional control lever and horn actuating arrangement of claim 1 wherein said movable element bridges said first and second contact members in said second position of the movable element, electrically connecting said first and second contact members and operating said horn.
Claim 5
Dependent Claim
46 words
The directional control lever and horn actuating arrangement of claim 3 wherein said movable element has an electrically conducting inner contact tip and an electrically nonconducting outer portion, said contact tip being continually in sliding electrical contact with one of said first and second contact members.
