Abstract

A tire pressure measurement apparatus is provided with a housing including a dome-shaped cavity on a rear end, bottom projections, and a channel communicating with the cavity; a valve including a curved head complimentarily disposed in the cavity, an internally threaded cylindrical member projecting out of the head through the cavity into the channel wherein the cylindrical member is limited by either side of the channel; and an externally threaded fastener driven through the channel into the cylindrical member to threadedly secure the housing and the head of the valve together. The housing is configured to rotate about the valve along a lengthwise axis of the valve. The housing is configured to pivot about the valve along a line passing through the channel. The pivot of the housing about the valve is stopped when the housing contacts either side of the channel.

Claims

1. A tire pressure measurement apparatus comprising in combination:

a housing including a dome-shaped cavity formed on a rear end, a plurality of projections on a bottom, and a channel communicating with the cavity;

a valve including a curved head disposed in the cavity, an internally threaded cylindrical member projecting forwardly out of the head through the cavity into the channel wherein the cylindrical member is limited by either side of the channel; and

an externally threaded fastener driven through the channel into the cylindrical member to threadedly secure the housing and the head of the valve together;

wherein the housing is configured to rotate about the valve along a lengthwise axis of the valve;

wherein the housing is configured to pivot about the valve along a line passing through the channel; and

wherein the pivot of the housing about the valve is stopped when the cylindrical member contacts either side of the channel.
