  • Patent number: 10488440
    Abstract: A meter cover removal detection arrangement includes a switch element, a pivoting lever arm, a meter cover and a plunger. The switch element has first and second positions, and conducts electricity between first and second contacts in only one of the first position and the second position. The pivoting lever arm has two arm positions, and is operably coupled to cause the switch element to be in the second position when the lever arm is in a second arm position. The lever arm engages a spring that biases the level arm toward the second arm position. The meter cover has an inward extending cam. The plunger has first and second plunger positions, and is operably coupled to hold the pivoting lever arm in the first arm position when the plunger is in the first plunger position. The cam engages the plunger to hold the plunger in the first plunger position when the meter cover is installed on a meter base. The cam is disengaged from the plunger when the meter cover is removed.

  • Patent number: 9829517
    Abstract: An arrangement for use in a utility meter includes an actuator element configured for linear movement. The actuator is operably coupled to receiving moving power from a prime mover, and includes a plurality of receptacles for corresponding contact arms of a switch within an electricity meter. Each receptacle is defined by an outer bar, an inner bar, and opposing stiffening elements. The outer bar is configured to engage a first surface of a contact arm element when the switch is in a first position, and the inner bar configured to engage a second surface of the contact arm element when the switch is in a second position.

  • Patent number: 7197797
    Abstract: A method for manufacturing a vehicle door hinge having a hinge axis, the method including providing a first hinge part having a first arm and a second arm axially spaced from the first arm, the hinge axis passing through the first arm and the second arm. The method also includes bending a strip of material to form a second hinge part having a first end, a second end, and a bent section between the first end and the second end, the first end having a first section and the second end having a second section, the first section and the second section being parallel relative to one another. In addition, the method includes fixing the first section and the second section relative to one another, and disposing the bent section between the first and second arms about the hinge axis.

  • Patent number: 6836933
    Abstract: A motor vehicle door hinge with a hinge axis includes a first hinge part and a second hinge part. The first hinge part has a first arm and a second arm axially spaced from the first arm with the hinge axis passing through the first arm and the second arm. The second hinge part includes a continuous strip of material having a first end, a second end, and a bent section between the first end and second end. The bent section is disposed between the first arm and second arm about the hinge axis. The first end has a first section and the second end has a second section. The first section and second section are parallel and fixed relative to each other.

  • Patent number: 6443846
    Abstract: A torque-limiting slip mechanism for a spare tire carrier includes a camshaft with a plurality of mating surfaces and differently shaped intermediate segments, a tire carrier drive with an inner pocket circumscribed by an interior wall, and a plurality of free-floating arcuate spring elements having a central body and ends that are compressed between the mating surfaces of camshaft and the interior wall. The central body engages the camshaft and the free ends engage the interior wall. In practice the spring elements are automatically centered with respect to their mating surface before a torque is applied. When the torque is greater than the pre-determined torque, however, each spring element deforms elastically as it selectively engages mating surfaces and intermediate segments so that the camshaft rotates with respect to the carrier drive.
