Abstract
Abstract The present invention is directed to a transmission shift mechanism having a shift lever with a ball means between its ends which is located in a housing and supported thereby against transverse horizontal movement. An elastomeric means is seated in the housing with a vent therethrough in order to prevent vertical upward movement of the ball portion and vibration producing metal-to-metal contact between ball and housing while allowing breathing simultaneously. A spring means is located at the opposite side of the ball means in order to prevent corresponding downward movement of the ball portion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
73 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means intermediate its ends; a housing means having an annular recess to support said ball portion of the shift lever along its horizontal plane against transverse movement of said shift lever; a vented elastomeric means seated in the annular recess of said housing means; and a spring means for biasing said ball portion upwardly against said elastomeric and housing means.
Claim 2
Dependent Claim
73 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means intermediate its ends; a housing means having an annular recess to support said ball portion of the shift lever along its horizontal plane against transverse movement of said shift lever; a vented elastomeric means seated in the annular recess of said housing means; and a spring means for biasing said ball portion upwardly against said elastomeric and housing means.
Claim 3
Dependent Claim
104 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means with upper and lower portions intermediate its ends; a housing means having an annular recess to support said ball means of the shift lever along its horizontal plane against transverse movement of said shift lever; a vented elastomeric means seated in the annular recess of said housing means for supporting said upper ball portion of said shift lever against the vertical upward movement of said ball portion and permitting the transmission to breath; and a spring means for biasing said lower ball portion upwardly against said elastomeric and housing means.
Claim 4
Dependent Claim
104 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means with upper and lower portions intermediate its ends; a housing means having an annular recess to support said ball means of the shift lever along its horizontal plane against transverse movement of said shift lever; a vented elastomeric means seated in the annular recess of said housing means for supporting said upper ball portion of said shift lever against the vertical upward movement of said ball portion and permitting the transmission to breath; and a spring means for biasing said lower ball portion upwardly against said elastomeric and housing means.
Claim 5
Dependent Claim
28 words
A transmission shift mechanism as recited in claim 2 and further characterized by the vented elastomeric means preventing metal-to-metal contact between said ball portion and said housing means.
Claim 6
Dependent Claim
16 words
A transmission shift mechanism as recited in claim 3 wherein the elastomeric means is an O-ring.
Claim 7
Dependent Claim
130 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means with upper and lower portions intermediate its ends; a housing means having an annular recess to support said ball means of the shift lever along its horizontal plane against transverse movement of said shift lever; a tower boot affixed to the top portion of said housing means in order to flex and prevent dust from entering said housing means during transmission operation; a vented elastomeric means seated in the annular recess of said housing means for supporting said upper portion of said shift lever against the vertical upper movement of said ball portion and permitting the transmission to breath; and a spring means for biasing said lower ball portion upwardly against said elastomeric and housing means.
Claim 8
Dependent Claim
130 words
A transmission shift mechanism comprising, in combination: a shift lever having a ball means with upper and lower portions intermediate its ends; a housing means having an annular recess to support said ball means of the shift lever along its horizontal plane against transverse movement of said shift lever; a tower boot affixed to the top portion of said housing means in order to flex and prevent dust from entering said housing means during transmission operation; a vented elastomeric means seated in the annular recess of said housing means for supporting said upper portion of said shift lever against the vertical upper movement of said ball portion and permitting the transmission to breath; and a spring means for biasing said lower ball portion upwardly against said elastomeric and housing means.
Claim 9
Dependent Claim
36 words
A transmission shift mechanism as recited in claim 5 and further including washer means for vertically alignment so that uniform biasing pressure is transferred from the spring means to the ball means through said washer means.
Claim 10
Dependent Claim
16 words
A transmission shift mechanism as recited in claim 5 Wherein the elastomeric means is an O-ring.
