Abstract
Abstract A control lever assembly wherein a plurality of levers are swingably mounted on a common shaft which is mounted in the housing of the unit. The assembly further includes interconnecting structure associated with the levers and associated apparatus connected to the links. The components are subassembled and tested prior to the placement of the assembly on a machine, such as a tractor, as a packaged unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
235 words
In a manually operable machine having a plurality of selectively operable mechanisms, and a support, an improved control lever assembly comprising: a first shaft; first mounting means for mounting a first portion of said first shaft to said support for rotation about the axis thereof; a first lever connected to said first shaft for manually rotating said first shaft about said axis; a tubular second shaft; second mounting means for mounting said second shaft coaxially about said first shaft for independent rotation of said second shaft about said axis; a second lever connected to said second shaft for manually rotating said second shaft about said axis; a tubular third shaft; third mounting means for mounting said third shaft coaxially about said second shaft for independent rotation of said third shaft about said axis; a third lever connected to said third shaft for manually rotating said third shaft for rotation about said axis; fourth mounting means for mounting said third shaft to said support at a position spaced axially from said first portion of the first shaft, said control lever assembly being rotatably supported by the rotatable mounting of each of different shafts thereof to a single one of different axially spaced portions of the support; and connecting means extending between said shafts and said mechanisms for operating said mechanisms selectively as a result of selective rotation of said shafts by selective manipulation of said levers.
Claim 2
Dependent Claim

In a manually operable machine having a plurality of selectively operable mechanisms, and a support, an improved control lever assembly comprising: a first shaft; first mounting means for mounting a first portion of said first shaft to said support for rotation about the axis thereof; a first lever connected to said first shaft for manually rotating said first shaft about said axis; a tubular second shaft; second mounting means for mounting said second shaft coaxially about said first shaft for independent rotation of said second shaft about said axis; a second lever connected to said second shaft for manually rotating said second shaft about said axis; a tubular third shaft; third mounting means for mounting said third shaft coaxially about said second shaft for independent rotation of said third shaft about said axis; a third lever connected to said third shaft for manually rotating said third shaft for rotation about said axis; fourth mounting means for mounting said third shaft to said support at a position spaced axially from said first portion of the first shaft, said control lever assembly being rotatably supported by the rotatable mounting of each of different shafts thereof to a single one of different axially spaced portions of the support; and connecting means extending between said shafts and said mechanisms for operating said mechanisms selectively as a result of selective rotation of said shafts by selective manipulation of said levers.
Claim 3
Dependent Claim
25 words
The machine structure of claim 1 wherein said support comprises a housing enclosing said shafts and have an opening through which said levers movably extend.
Claim 4
Dependent Claim
14 words
The machine structure of claim 1 wherein said mounting means comprise roller bearing means.
Claim 5
Dependent Claim
14 words
The machine structure of claim 1 wherein said support means comprise needle bearing means.
Claim 6
Dependent Claim
14 words
The machine structure of claim 1 wherein said mechanisms are mounted to said support.
Claim 7
Dependent Claim
60 words
The machine structure of claim 1 wherein said support comprises a housing enclosing said shafts and have openings through which said levers movably extend, said mechanisms being mounted to said support whereby said control lever assembly and said mechanisms may be assembled as a packaged unit for bench testing prior to installation in the machine as a pretested packaged unit.
Claim 8
Dependent Claim
44 words
The machine structure of claim 1 wherein said support defines a first pivot means for journaling said first shaft and second pivot means for journaling said third shaft, said first shaft being effectively additionally journaled to said support through said second and third shafts.
Claim 9
Dependent Claim
18 words
The machine structure of claim 1 wherein said levers are juxtaposed at one end of said first shaft.
Claim 10
Dependent Claim
35 words
The machine structure of claim 1 wherein said levers are juxtaposed at one end of said first shaft and said first shaft is journaled in said support at the opposite end of said first shaft.
