Abstract: A key ring is provided wherein a rigid wire loop fits through the opening in the top of keys or other small items to be retained thereon. The wire loop has a break in it in order to permit the keys to be threaded over it. In order to close the opening, the ends of the wire loop are retained in a closure including a housing formed of a front and a back portion defining a cavity therebetween. The front and back portions are releaseably connected together and contain, in the cavity formed therebetween, a retaining member having a pair of aligned slots which receive the ends of the wire loop. In this way, the end portions of the loop are positively supported and locked in the housing.

Abstract: An indicating apparatus for measuring the pressure of a fluid within a container, such as a tire, which includes a housing adapted to be mounted on the tire valve assembly. A plunger is supported within the housing for movement between an inoperable position wherein the tire valve is closed and a first operate position wherein the valve is opened to permit fluid from the tire to enter the housing. An indicator piston is supported within the housing for movement to an indicating position representative of the pressure within the tire, which position is exposed to view through the housing. The apparatus further provides for movement of the plunger to a second operate position wherein the valve is opened to permit pressure from an external source to be transmitted to the tire through the apparatus without having to remove the apparatus from the tire valve assembly.
