ABSTRACT:
This invention discloses an improved pressure gauge adaptable to simultaneously indicate multi-linear scale of the tire pressure. This pressure gauge has a tubular member having a first and a second end, a tire valve engaging head attached to the first end of the tubular member, and a compression spring having a first and a second end. A piston provided movably at the first end of the compression spring and a frame. The frame has a substantially U-shaped configuration with a transverse portion interconnecting two opposed leg portions, each of the leg portions having an inner and an outer side wall. The inner side walls of the leg portion are each provided with two guide slots formed longitudinally therein which extend in parallel to each other. In addition this pressure gauge includes at least two graduated bars each having a front and a reverse side wall which have different linear scales printed thereof, and two side walls each having two side edges provided therealong in parallel to each other for movement with respect to the longitudinal guide slots, and being in contact with the piston. The graduated bar is substantially cruliform-shaped. A cover with an opening frictionally engages the graduated bar and fits into the second end of the tubular member.
