摘要： An electric meter particularly characterized by a small number of moving parts and simplified assembly by virtue of fixed cooperating locating surfaces on the elements and sub-assemblies of the meter. A magnetic circuit including a yoke and magnet are constructed to snap into an insulating base in a predetermined position on the base. A coil assembly is accurately positioned for rotation on the supporting base. Cooperating locating surfaces provide for accurate predetermined positioning of the axis of rotation of the coil relative to the magnetic circuit. Additional features of the meter construction reside in a zero adjust knob mounted in a cover for the meter, a unique base, casing, and cover which snap together, a coil support frame of unique construction and which includes motion limiting elements which limit the permissible extent of movement of the coil in the event of shock or impact to positions well within the elastic limit of the suppports which mount the coil for rotation, whereby the number of different parts required to form meters of different sizes is maintained at a minimum, a unique insulating material base with flexibility to permit expanding the base during assembly of the meter, and sub-assemblies, components, and elements which can be assembled in only one position and orientatiion to assure proper assembly of the meter.

摘要： A visual indicator includes a concave reflecting surface having an opening therein. An optical image-producing element moves into and out of the opening under the guidance of an electrical meter movement. The electrical meter movement responds to an electrical signal so that the image produced by the visual indicator is related to the magnitude of the electrical signal applied to the meter movement.

摘要： An electric meter particularly characterized by a small number of moving parts and simplified assembly by virtue of fixed cooperating locating surfaces on the elements and sub-assemblies of the meter. A magnetic circuit including a yoke and magnet are constructed to snap into an insulating base in a predetermined position on the base. A coil assembly initially including integral elements for connection of pivot bearings or taut bands is accurately positioned for rotation on the supporting base by inserting the assembly into the base. Cooperating locating surfaces provide for accurate predetermined positioning of the axis of rotation of the coil relative to the magnetic circuit. Additional features of the meter construction reside in a direct gear drive between a zero adjust element and zero adjust knob mounted in a cover for the meter, a unique base, casing, and cover which snap together, a coil support form of unique construction and which includes motion limiting elements which limit the permissible extent of movement of the coil in the event of shock or impact to positions well within the elastic limit of the supports which mount the coil for rotation, a unique mode of terminating the end connections for the coil without the need for stripping insulation, a unique mounting arrangement for the assembled meter, a unique rear mounting scale plate which provides for easily replacing scale plates to meet the needs of the user of the meter, a meter movement of a single size adapted to be used with casings and scales of various sizes whereby the number of different parts required to form meters of different sizes is maintained at a minimum, a unique insulating material base with flexibility to permit expanding the base during assembly of the meter, and sub-assemblies, components, and elements which can be assembled in only one position and orientation to assure proper assembly of the meter.

摘要： A rotary coil for an electrical measuring instrument is made by providing the coil frame with a winding and with needle bearings. A pointer is mounted on the frame and a section of synthetic plastic material is mounted on the frame as a counterbalance. The section is heavier than the pointer and is provided with an arcuate wall portion curved over a portion of arc with a plane of symmetry coinciding with the axis of rotation of the frame. The wall portion is then provided with one or more slots so located, and with sufficient material being removed, that the existing imbalance is corrected and the coil is balanced.

摘要： In a taut band suspension instrument in which each taut band extends between two convex support surfaces and the end portions of the taut band are secured to the respective supports by fused metal connections at points spaced radially from the axis defined by the band, the support surface at the end of the band farther from the rotor is provided with a shallow groove, the bottom of the groove being continuous and uninterrupted and having a width at least twice the width of the taut band, the support surface at the other end of the band being smooth and unbroken for the full width thereof. The combination of the two support surfaces allows the taut band to shift laterally when the instrument is under shock, yet assures that the outer end of the taut band will be properly oriented when installed and thereafter.
