Abstract
Abstract A two and four wheel drive indicator is provided in a push-pull handle that is used for conditioning a vehicle for either two or four wheel drive operation. The indicator is actuated by a slidable rod within the handle which comes into contact with a base or supporting surface for the handle as the handle is pushed toward the base or supporting surface. A symbol, representing the four wheel drive condition, appears on a cover plate on the handle whenever the handle is actuated to condition the vehicle for a four wheel drive operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
A four wheel drive indicator signal for a vehicle, comprising: a support surface; a handle having one side visible to the operator and a second side adjacent to the support surface; a control lever connected to the second side of the handle and extending through an aperture in the support surface and linearly movable to-and-fro for selectively engaging and disengaging the vehicle into and out of four wheel drive operation; a guide rod extending parallel to the control lever slidably mounted in the handle and having an end projecting from the second side of the handle and engagable with the support surface after a predetermined distance of movement of the handle toward the support surface; a cover plate mounted to the one side of the handle and having means for visually signalling the four wheel drive engaged condition of the vehicle; and an illuminating means carried on the other end of the guide rod movable toward the signalling means on the cover plate for illuminating same simultaneously with the projecting end of the guide rod contacting the support surface and the handle moving relative to the guide rod towards the support surface.
Claim 2
Dependent Claim

A four wheel drive indicator signal for a vehicle, comprising: a support surface; a handle having one side visible to the operator and a second side adjacent to the support surface; a control lever connected to the second side of the handle and extending through an aperture in the support surface and linearly movable to-and-fro for selectively engaging and disengaging the vehicle into and out of four wheel drive operation; a guide rod extending parallel to the control lever slidably mounted in the handle and having an end projecting from the second side of the handle and engagable with the support surface after a predetermined distance of movement of the handle toward the support surface; a cover plate mounted to the one side of the handle and having means for visually signalling the four wheel drive engaged condition of the vehicle; and an illuminating means carried on the other end of the guide rod movable toward the signalling means on the cover plate for illuminating same simultaneously with the projecting end of the guide rod contacting the support surface and the handle moving relative to the guide rod towards the support surface.
Claim 3
Dependent Claim
58 words
A four wheel drive indicator signal for a vehicle, according to claim 1, wherein the illuminating means comprise a slide mounted to said other end of the guide rod and slidable guided in an opening in the handle formed to the shape of the slide, and a luminescent indicator is connected to the slide beneath the signalling means.
Claim 4
Dependent Claim
64 words
A four wheel drive indicator signal for a vehicle, according to claim 2, wherein a leaf spring connects the slide to said other end of the guide rod, and the slide is slidable transversely to the guide rod in the opening in the handle, and a compression spring opposes the leaf spring and urges the slide and luminescent indicator away from the signalling means.
Claim 5
Dependent Claim
60 words
A four wheel drive indicator signal for a vehicle, according to claim 2, wherein a rigid link pivotally connects the slide to said other end of the guide rod, and the slide is slidable transversely to the guide rod in the opening in the handle, and a compression spring urges the slide and luminescent indicator away from the signalling means.
Claim 6
Dependent Claim
66 words
A four wheel drive indicator signal for a vehicle, according to claim 2, wherein one arm of a rocker arm link is pivotally connected to said other end of the guide rod and a second arm of the rocker arm link is slidably connected to the slide, and a compression spring urging the second arm and the slide and the luminescent indicator toward the signalling means.
Claim 7
Dependent Claim
43 words
A four wheel drive indicator signal for a vehicle, according to claim 2, wherein the opening in the handle extends parallel to the guide rod whereby the slide in the opening slides parallel to the guide rod to and from the signalling means.
