Abstract

Abstract A tire of a vehicle having a finder is supported on a pair of tire cradling rollers driven by a motor connected by a belt to one of the rollers. Two sensor units are connected to a vehicle motion follower responsive to the movement of the finder due to tire strength variations around the circumference of the tire to effect indications of vehicle movement and maximum range of vehicle movement.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 122 words
Apparatus for displaying the supporting strength characteristics of a tire while rotating and supporting its share of the vehicle load conditions, said apparatus comprising means to follow the vehicle movement caused by tire strength variations around its circumference including a probe engaged on the vehicle; first sensor means operably connected to said vehicle movement follower means and responding to the maximum range of the vehicle movement, second sensor means operably connected to said vehicle movement follower means to continuously respond to such vehicle movement, and visual display means operably connected to said first and second sensor means to display the maximum range of vehicle movement and the vehicle movement caused by the presence of variations in the tire strength about its circumference.
Claim 2
Dependent Claim 122 words
Apparatus for displaying the supporting strength characteristics of a tire while rotating and supporting its share of the vehicle load conditions, said apparatus comprising means to follow the vehicle movement caused by tire strength variations around its circumference including a probe engaged on the vehicle; first sensor means operably connected to said vehicle movement follower means and responding to the maximum range of the vehicle movement, second sensor means operably connected to said vehicle movement follower means to continuously respond to such vehicle movement, and visual display means operably connected to said first and second sensor means to display the maximum range of vehicle movement and the vehicle movement caused by the presence of variations in the tire strength about its circumference.
Claim 3
Dependent Claim 19 words
The apparatus of claim 1 wherein said first sensor means includes a potentiometer operatively connected to said follower means.
Claim 4
Dependent Claim 27 words
The apparatus of claim 1 wherein said second sensor means includes a stator winding and a magnetic armature, said armature being connected operatively to said follower means.
Claim 5
Dependent Claim 27 words
The apparatus of claim 1 wherein said first sensor means includes a resistance and a contact brush relatively movable and each operatively connected to said follower means.
Claim 6
Dependent Claim 25 words
The apparatus of claim 4 wherein other means is operatively engaged with said resistance and contact brush to retain the same in relative moved positions.
Claim 7
Dependent Claim 162 words
Apparatus for displaying the strength characteristics of a tire while rotating and supporting its share of the vehicle load conditions, said apparatus comprising vehicle motion following means having a probe engaged adjacent one end with the vehicle; a stationary support engaged with said follower means said follower means being yieldable from an initial position to follow vehicle motion transmitted by said probe; vehicle motion sensing means carried by said stationary support including a movable resistance and a movable brush engaging said resistance; drive means operatively connected between said stationary support and each of said resistance and brush; yieldable means operatively biasing said resistance and brush to a predetermined starting position; holding means yieldably retaining said resistance and brush in relative moved positions in accordance with vehicle motion transmitted by said drive means; electrical meter display means; and circuit connections between said display means and said resistance and brush, including an adjustable resistance to bring said display means initially to a zero setting.
Claim 8
Dependent Claim 162 words
Apparatus for displaying the strength characteristics of a tire while rotating and supporting its share of the vehicle load conditions, said apparatus comprising vehicle motion following means having a probe engaged adjacent one end with the vehicle; a stationary support engaged with said follower means said follower means being yieldable from an initial position to follow vehicle motion transmitted by said probe; vehicle motion sensing means carried by said stationary support including a movable resistance and a movable brush engaging said resistance; drive means operatively connected between said stationary support and each of said resistance and brush; yieldable means operatively biasing said resistance and brush to a predetermined starting position; holding means yieldably retaining said resistance and brush in relative moved positions in accordance with vehicle motion transmitted by said drive means; electrical meter display means; and circuit connections between said display means and said resistance and brush, including an adjustable resistance to bring said display means initially to a zero setting.
Claim 9
Dependent Claim 26 words
The apparatus of claim 6 wherein means is operatively connected to said holding means to release said resistance and brush for return to said starting position.
Claim 10
Dependent Claim 52 words
The apparatus of claim 6 wherein a second vehicle motion sensing means on said stationary support is operatively connected to said vehicle motion follower means to respond to the rate of vehicle motion during tire rotation, and second display means is connected to said second sensing means to display such vehicle motion.
Claim 11
Dependent Claim 55 words
The apparatus of claim 8 wherein said second sensing means includes a stator coil, a spring biased magnetic armature operatively connected to said follower means to move in response to vehicle motion and circuit means connected to said stator coil and to said second display means to continuously display vehicle motion response during tire rotation.
Claim 12
Dependent Claim 48 words
The apparatus of claim 9 wherein reset means is operatively connected to said holding means to release said resistance and brush for return to said starting position, and said spring biased magnetic armature responding to said reset means to urge said follower means to its said initial position.
