Abstract
Abstract An air pressure testing apparatus connected to a conventional valve stem of a pneumatic tire is operable to provide visual color information as to the pressure of the air in the tire. The apparatus has a body mounted on the valve stem. A transparent housing having circumferential beads is mounted on the body. A spring biased annular piston located between the housing and body has color code information. Separate colors on the piston are visually observable through the beads as determined by the longitudinal position of the piston relative to the beads. An elongated plunger extended through the body is movable to open the valve in the valve stem to subject the annular piston to the air pressure of the tire. If the air pressure is above a predetermined pressure, the piston will move changing the color code observable through the beads. If the air pressure is below the predetermined pressure, the piston will not move and the color code will remain the same. The plunger is movable to a position wherein air under pressure can be introduced into the tire.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
82 words
An optical read out apparatus to provide visual information as to the existence of a condition comprising: first means having a viewing section, second means movable relative to and adjacent the viewing section in response to a condition, said second means having information means indicating the condition, said viewing section including a transparent section having at least one annular outwardly divided bead, said bead providing an optical structure for viewing the information means when the information is located adjacent the transparent section.
Claim 2
Dependent Claim
82 words
An optical read out apparatus to provide visual information as to the existence of a condition comprising: first means having a viewing section, second means movable relative to and adjacent the viewing section in response to a condition, said second means having information means indicating the condition, said viewing section including a transparent section having at least one annular outwardly divided bead, said bead providing an optical structure for viewing the information means when the information is located adjacent the transparent section.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein: the transparent section has a plurality of side-by-side annular outwardly directed beads providing optical structure for viewing the information means.
Claim 4
Dependent Claim
30 words
The apparatus of claim 1 wherein: the first means is a generally cylindrical member, and the second means is a sleeve located within the cylindrical member and movable relative thereto.
Claim 5
Dependent Claim
23 words
The apparatus of claim 3 including: means to bias the sleeve to a position wherein the information means does not indicate the condition.
Claim 6
Dependent Claim
26 words
The apparatus of claim 1 wherein: the second means has first information means indicating the condition and second information means indicating the non-existence of the condition.
Claim 7
Dependent Claim
16 words
The apparatus of claim 5 wherein: the first and second information means are contrasting colored bands.
Claim 8
Dependent Claim
109 words
An optical readout apparatus to provide information as to the existence of a condition comprising: a first cylindrical means having a viewing section, said viewing section having a plurality of axially spaced annular outwardly directed bead means, said bead means providing optical structures for viewing the area on the inside of said cylindrical means, and second cylindrical means concentrically positioned within the first cylindrical means and movable relative to the viewing section in response to a condition, said second means having information indicating the condition, and means to move the second means relative to the first means to a position wherein the information means does not indicate the condition.
Claim 9
Dependent Claim
109 words
An optical readout apparatus to provide information as to the existence of a condition comprising: a first cylindrical means having a viewing section, said viewing section having a plurality of axially spaced annular outwardly directed bead means, said bead means providing optical structures for viewing the area on the inside of said cylindrical means, and second cylindrical means concentrically positioned within the first cylindrical means and movable relative to the viewing section in response to a condition, said second means having information indicating the condition, and means to move the second means relative to the first means to a position wherein the information means does not indicate the condition.
Claim 10
Dependent Claim
26 words
The apparatus of claim 7 wherein: the second means has first information means indicating the condition and second information means indicating the non-existence of the condition.
Claim 11
Dependent Claim
16 words
The apparatus of claim 8 wherein: the first and second information means are contrasting colored bands.
Claim 12
Dependent Claim
37 words
The apparatus of claim 7 wherein: the means to move the second means includes biasing means to bias the second means to a first position relative to the first means to indicate the non-existence of the condition.
Claim 13
Dependent Claim
15 words
The apparatus of claim 7 wherein: the second means is a fluid pressure actuated piston.
Claim 14
Dependent Claim
25 words
The apparatus of claim 7 wherein: the viewing section has three circumferential beads, said beads located in side-by-side longitudinal position along the first cylindrical means.
Claim 15
Dependent Claim
50 words
The apparatus of claim 7 wherein: the information means comprises a first means being a colored band transversely aligned with said beads when the piston is in a first position and second means being a colored band transversely aligned with said beads when the piston is in a second position.
