Inflation and pressure indicator apparatus for tires
First Claim
1. Apparatus for inflating a tire connected to a tire rim and indicating the pressure of said tire while the tire in on said rim, said apparatus comprising, in combination;
- an elongated body element having an outer cylindrical surface for connection with said tire rim and defining an elongated passageway leading from the interior of the tire to which said elongated body element is connected to the ambient atmosphere;
an elongated valve element having indicia thereon slidably disposed within said elongated passageway and moveable between an extended position wherein said elongated valve element extends at least partially out of said elongated body element to display the indicia on said elongated valve element and a fully retracted position wherein said elongated valve element is fully retracted into said elongated body element and does not extend outwardly therefrom;
seal means attached to said elongated valve element, said seal means engaging said elongated body element when in said extended position and disengaged from said elongated body element when in said fully retracted position;
spring means within said elongated body element operatively associated with said elongated valve element for biasing said elongated valve element against movement toward said extended position;
tire rim mounting means extending about the other cylindrical surface of said elongated body element and selectively moveable along at least a portion of the length of said elongated body element; and
securement means for securing said mounting means at a predetermined location along the length of said elongated body element, said securement means including a plurality of spaced detents extending along at least a portion of the length of said elongated body element for frictionally engaging said securement means.

Abstract
Apparatus for inflating a tire connected to a tire rim and indicating the pressure of a tire while the tire is on the rim includes an elongated body element for connection with the tire rim, an elongated valve element having indicia thereon slidably disposed within an elongated passageway within the elongated body element, a seal attached to the elongated valve element, and a spring for biasing the elongated valve element against movement toward an extended position. The elongated valve element is moveable to a fully retracted position within the elongated body element and allows pressurized air to flow between the elongated body element and the elongated valve element when the apparatus is used to fill a tire.
