Utility line angle measurement device

An angle measurement device intended to enable quick, accurate measurement by one person of the angle subtended by a utility line at a given utility pole, said device comprising:

• a frame, a protractor, a pointer, horizontal determination means, positioning means and plumb adjustment means;
• said frame possessing both a longitudinal and a vertical component, said protractor possessing a central axis and a face divided into four ninety degree quadrants possessing two opposed zero degree markings through which a baseline extends, said pointer and said protractor each being rotatable about said central axis fixed perpendicular to said longitudinal frame component such that said protractor face and said pointer are confined to rotation within parallel planes proximate each other and fixed in relation to said frame;
• said horizontal determination means comprising a device sensitive to gravity in two degrees of freedom further possessing a horizontal reference plane fixed parallel to said plane of rotation of said protractor face by fixed attachment to said frame;
• said positioning means possessing a component extending forward of said vertical frame component which, brought in contact with said given pole in operation, effects a contact axis and facilitates maintenance of the disposition of said axis with respect to said pole;
• said plumb adjustment means possessing a component extending forward of said vertical frame component, vertically offset from said contact axis which, in contact with said given pole, enables manual regulation of the orientation of the device with respect to the plane perpendicular to said contact axis;
• said protractor face baseline and said pointer each possessing visual sighting means enabling visual alignment of each with a vertical pole adjacent said given pole;
• said horizontal determination means in combination with said positioning means enabling level orientation of said contact axis and maintenance of said level orientation, said horizontal determination means in combination with said plumb adjustment means enabling level orientation of the device in a plane perpendicular to said contact axis and maintenance of said level orientation, the effecting and maintenance of said level orientations of both said contact axis and said plane perpendicular to said contact axis thereby effecting a horizontal disposition of said protractor face and said pointer, said visual sighting means facilitating the visual alignment of said baseline with one adjacent pole and visual alignment of said pointer with the other pole adjacent to said given pole against which said device is positioned thereby yields by reading of the degree markings indicated by said pointer relative said protractor face a measurement of the angle subtended by the two alignments of the given pole with the two adjacent poles within a horizontal plane and hence yields an accurate measurement of the angle subtended by said line at said given utility pole quickly and readily obtained by one person.
