Abstract
Abstract A lever control for an engine transmission and the like having a transverse shaft secured in spaced frame plates and a face plate or cover traversing the outer edges of said spaced plates. A handle lever extends through the face plate and is connected to a control actuator plate rotatable on the shaft, and a detent operable from the handle lever is biased to normally engage selectively in a notched positioning gate mounted on one of said frame plates. An arcuate housing enclosing the gate and detent is mounted on the handle lever extending through the face plate. A preferred embodiment has a visual indicator showing the control positions which is illuminated to be visible day and night.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
Lever control mechanism comprising a frame having spaced-apart mounting plates and a substantially flat cover plate traversing the outer ends of said plates, a transverse shaft secured in said mounting plates, a control plate rotatable on said shaft, a handle lever connected to said control plate and extending through said cover plate, a gate plate having a series of indentations secured to one of said mounting plates, a detent slidable on said lever and biased to engage selectively in said indentations, and an arcuate channeled housing attached to said lever extending movably and outwardly through and in sealed relation to said cover plate and enclosing said gate and detent mechanism.
Claim 2
Dependent Claim
110 words
Lever control mechanism comprising a frame having spaced-apart mounting plates and a substantially flat cover plate traversing the outer ends of said plates, a transverse shaft secured in said mounting plates, a control plate rotatable on said shaft, a handle lever connected to said control plate and extending through said cover plate, a gate plate having a series of indentations secured to one of said mounting plates, a detent slidable on said lever and biased to engage selectively in said indentations, and an arcuate channeled housing attached to said lever extending movably and outwardly through and in sealed relation to said cover plate and enclosing said gate and detent mechanism.
Claim 3
Dependent Claim
62 words
Lever control mechanism as defined in claim 1, wherein said notches allow the detent pin to ratchet from the notch at one end of said series to the next to last notch at the other end, and means on the handle lever yieldingly resisting sliding of said detent pin on said lever to allow said pin to ratchet into said last notch.
Claim 4
Dependent Claim
33 words
Lever control mechanism as defined in claim 1, wherein the exterior of said cover plate has a control position scale thereon and the exposed portion of said housing carries a cooperating visual indicator.
Claim 5
Dependent Claim
26 words
Lever control mechanism as defined in claim 2, wherein means for illuminating said scale and visual indicator is mounted on the inside of said cover plate.
Claim 6
Dependent Claim
40 words
Lever control mechanism as defined in claim 4, wherein the visual indicator is a linear transparent material extending within the cover plate and adapted for transmitting light from an interior light source to the exposed portion of the visual indicator.
Claim 7
Dependent Claim
51 words
Lever control mechanism as defined in claim 1, wherein the indentations are notches and the detent is a pin biased to engage selectively in said notches and rotatably mounted in an actuator bar slidable on said handle lever, and bar sliding means is mounted on the exposed portion of said lever.
Claim 8
Dependent Claim
61 words
Lever control mechanism as defined in claim 6, wherein a second control plate is spaced from and parallel to said first control plate and the actuator bar is slidably mounted between the control plates, a biasing pin is mounted in the inner end of said actuator bar, and a biasing spring is interposed between said biasing pin and said control plates.
Claim 9
Dependent Claim
60 words
Lever control mechanism as defined in claim 6, wherein said notches allow the detent pin to ratchet from the notch at one end of said series to the next to last notch at the other end, and means on the handle lever yieldingly resisting sliding of the actuator bar to allow the detent pin to ratchet into said last notch.
