    Abstract: A drilling rig load indicator for use on a mobile drilling rig of the type which is provided with means for applying a downward force to a drill string and bit and for applying a lifting force to raise the drill string and bit, and being further provided with a hydraulic pressure source which operates a plurality of hydraulic jacks to support and level the drilling rig. The drilling rig load indicator is composed of a hydraulic totalizer, a pressure indicator, and, a plurality of hydraulic pressure gauges. The hydraulic totalizer has an input side which is connected by means of conduits to the hydraulic jacks and an output side which represents the summation of the loads upon the hydraulic jacks. In the event that the conduits cannot be connected to the hydraulic jacks, the conduits may be connected to separate hydraulic load cells which are placed between the hydraulic jacks and the earth. The pressure indicator, which is connected to the output side of the totalizer, and is adapted to visually display the summation of the loads upon the hydraulic jacks or load cells, is provided with a dial face that has two sectors, one sector representing the amount of applied downward force, the other representing the amount of applied lifting force. The hydraulic pressure gauges are each connected to a hydraulic jack or load cell and are adapted to visually display the load thereupon.

    Abstract: A hydraulic load-sensing device disposed between a load carrying device in the form of a lifting hook and a hoist in the form of a crane jib includes a single-acting hydraulic piston and cylinder unit, the cylinder component being connected to the hoist jib and the piston component being connected to the lifting hook in such manner that as the hoist jib is raised in order to raise the load carried by the hook, a corresponding pressure is exerted on the hydraulic medium between the piston and the lower end of the cylinder and this pressure is transmitted from the cylinder through a line to a pressure gage which measures and exhibits the combined dead weight of the hook and its load.

    Abstract: A DIFFERENTIAL PRESSURE GAUGE INCLUDES A U-SHAPED TRANSPARENT TUBE HAVING LEGS AT ITS ENDS CONNECTED TO TWO IDENTICAL CLOSED PRESSURE RESPONSIVE ELEMENTS ENCLOSED IN CASINGS TO WHICH CONDUITS FROM TWO DIFFERENT PRESSURE SOURCES ARE CONNECTED. THE TUBE AND PRESSURE RESPONSIVE ELEMENTS ARE FILLED WITH TWO DIFFERENT FLUIDS MEETING AT A MENISCUS IN THE TUBE. A SCALE ADJACENT TO THE TUBE INDICATES THE POSITION OF THE MENISCUS AND PROVIDES A READING OF ANY CHANGE IN POSITION DUE TO CHANGE IN RELATIVE PRESSURES APPLIED TO THE TWO ELEMENTS. TWO IDENTICAL CLOSED EXPANSIBLE PRESSURE RESPONSIVE MEMBERS ARE CON-

    NECTED TO THE TWO LEGS OF THE TUBE TO EXPAND AND CONTACT EQUALLY WHEN PRESSURE IN THE TUBE CHANGES. VOLUME ADJUSTMENT MEANS MAY BE CONNECTED TO THE TUBE FOR ADJUSTING RELATIVE VOLUMES OF THE FLUIDS IN THE TUBE IN ACCORDANCE WITH ANY DIFFERENCE IN THERMAL COEFFEIENTS OF EXPANSION OF THE FLUIDS IN THE TUBE.
