Abstract: A locking device is provided which includes a body comprising a tube with a bore and a longitudinally-extending flange with a plurality of shackle receivers. The bore is adapted to slideably receive an elongate member, such as a load binder handle. The body is secured to a second member, for example a load binder connector or a load chain link, by a padlock including a case and a shackle receivable in a respective shackle receiver. With the padlock in its locked position, the elongate member and the second member are secured together.

Abstract: A pressure equalizing valve for pneumatic tires including a visual display is described which is ideally suited for use with dual tires. A cylindrical housing accommodates a spring biased diaphragm mounted in a first chamber. The diaphragm carries a valve member thereon and acts as a sealing member or element to close two air passageways which are in communication with the dual tires in a conventional dual tire installation. The valve member closes the air passageways when a pre-adjusted and calibrated value of air pressure is lost by the dual tires involved. Changes in the air pressures acting on the spring biased diaphragm are communicated to a diaphragm follower on the atmospheric side of the diaphragm. A visual display is operated with the diaphragm follower and responds at an eight to one ratio to the movement of the diaphragm and follower when air pressure changes occur and a resultant movement of the diaphragm and follower occurs.
