  • Gear actuated angle measurement tool
    Patent number: 8413344
    Abstract: A multiple gear driver having first and second fixed gears and first and second rotatable gears, the first fixed and rotatable gears located on a first member, and the second fixed and rotatable gears located on a second member, the first and second fixed gears having a common axis so that the first fixed gear drives the second rotatable gear and the second fixed gear drives the first rotatable gears when the first and second member are moved relative to each other.
    Type: Grant

  • GEAR ACTUATED ANGLE MEASUREMENT TOOL
    Publication number: 20110005093
    Abstract: An angle measurement tool having two legs joined together about a common axis so that one of the legs rotates with respect to the other to form a desired angle the value of which is read utilizing gears that are housed in said legs in combination with indicia means indicating the degree of rotation of the gears.

  • Angle measurement tool
    Patent number: 7406774
    Abstract: An angle measurement tool in which the assembled components result in only two moving parts that are pivoted relative to each other and wherein the pivot axis is the geographic center of the angle measurement component and wherein a miter joint angle, the correspondent actual angle, the complementary angle of the actual angle and the supplementary angle of the actual angle can be read simultaneously.

  • Angle measurement tool
    Patent number: 7278221
    Abstract: An angle measurement tool having two legs held together by a removable adjustment member in which the legs are joined together about a common axis so that one of the legs rotates with respect to the other to form a desired angle the value of which is read using indexing means located on both legs.
    Type: Grant

  • Angle measurement tool
    Patent number: 6804895
    Abstract: An angle measuring tool having pivotally connected members and an angle measurement index with and off center portion positioned so that upon the rotation of one member with respect to the other the angle between the two members can be accurately determined with no possibility of slippage of the angle measurement index due to the off center portion mating with one of the members.
