Abstract
Abstract A transmission ratio indicator has a lens assembly with a ratio selection indicia imprinted thereon. The transmission selector lever or an indicator associated therewith is selectively movable to various ratios and is aligned with the indicia to indicate the transmission operating condition. The lens assembly is secured in a housing by a resilient member and interengaging toothed portions formed on the lens assembly and housing. The lens assembly toothed portion can be disengaged from the housing toothed portion by displacement of the resilient member through application of a force to the lens assembly. When tooth disengagement has been attained, the lens assembly can be moved in the housing to attain proper alignment of the indicia and the shift lever or indicator. The adjusted position of the lens assembly is maintained by the resilient member enforcing the reengagement of the toothed portions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
201 words
An improvement in automatic transmission ratio indicating mechanisms having a position indicator movable in a transmission lever housing, and a lens structure attached to said housing with indicia disposed thereon which cooperate with said position indicator to indicate the transmission ratio selected, wherein the improvement comprises; a lens housing disposed in said transmission lever housing including a wall portion having two resilient finger members formed integral thereon, another wall portion having a pair of support flanges and two groups of housing teeth formed integral thereon, a lens member with the indicia thereon disposed between the wall portions and being urged toward the toothed wall portion by said resilient finger members, and two groups of lens teeth disposed on said lens member and cooperating with the respective wall portion teeth to position said lens member in said lens structure, said resilient finger members being operable to urge engagement between respective groups of teeth and said lens member being deflectable against said resilient member upon application of a force thereto for disengaging said respective groups of teeth to permit movement of said lens member in said lens housing relative to said position indicator to establish alignment of said position indicator and said indicia.
Claim 2
Dependent Claim
201 words
An improvement in automatic transmission ratio indicating mechanisms having a position indicator movable in a transmission lever housing, and a lens structure attached to said housing with indicia disposed thereon which cooperate with said position indicator to indicate the transmission ratio selected, wherein the improvement comprises; a lens housing disposed in said transmission lever housing including a wall portion having two resilient finger members formed integral thereon, another wall portion having a pair of support flanges and two groups of housing teeth formed integral thereon, a lens member with the indicia thereon disposed between the wall portions and being urged toward the toothed wall portion by said resilient finger members, and two groups of lens teeth disposed on said lens member and cooperating with the respective wall portion teeth to position said lens member in said lens structure, said resilient finger members being operable to urge engagement between respective groups of teeth and said lens member being deflectable against said resilient member upon application of a force thereto for disengaging said respective groups of teeth to permit movement of said lens member in said lens housing relative to said position indicator to establish alignment of said position indicator and said indicia.
Claim 3
Dependent Claim
215 words
An improvement in automatic transmission ratio indicating mechanisms having a position indicator movable in a transmission lever housing, and a lens structure attached to said housing with indicia disposed thereon which cooperate with said position indicator to indicate the transmission ratio selected, wherein the improvement comprises; a lens housing disposed in said transmission lever housing including a wall portion having two resilient finger members formed integral thereon, another wall portion having a pair of support flanges and two groups of housing teeth formed integral thereon, a lens member with the indicia thereon disposed between the wall portions and being urged toward the toothed wall portion by said resilient finger members, and two groups of lens teeth disposed on said lens member and cooperating with the respective wall portion teeth to position said lens member in said lens structure, said resilient finger members being operable to urge engagement between respective groups of teeth and said lens member being deflectable against said resilient member upon application of a force thereto resulting in bending of the lens member due to said support flanges thereby causing disengagement of said respective groups of teeth to permit movement of said lens member in said lens housing relative to said position indicator to establish alignment of said position indicator and said indicia.
Claim 4
Dependent Claim
215 words
An improvement in automatic transmission ratio indicating mechanisms having a position indicator movable in a transmission lever housing, and a lens structure attached to said housing with indicia disposed thereon which cooperate with said position indicator to indicate the transmission ratio selected, wherein the improvement comprises; a lens housing disposed in said transmission lever housing including a wall portion having two resilient finger members formed integral thereon, another wall portion having a pair of support flanges and two groups of housing teeth formed integral thereon, a lens member with the indicia thereon disposed between the wall portions and being urged toward the toothed wall portion by said resilient finger members, and two groups of lens teeth disposed on said lens member and cooperating with the respective wall portion teeth to position said lens member in said lens structure, said resilient finger members being operable to urge engagement between respective groups of teeth and said lens member being deflectable against said resilient member upon application of a force thereto resulting in bending of the lens member due to said support flanges thereby causing disengagement of said respective groups of teeth to permit movement of said lens member in said lens housing relative to said position indicator to establish alignment of said position indicator and said indicia.
