Abstract:
1. A comb, comprising: a handle portion having a first side and a second side, the handle portion defining a long axis; a plurality of regularly-spaced teeth connected to and depending from the handle portion; first and second grooves inset into the first and second sides of the handle portion, respectively, the first and second grooves being oriented along the long axis of the handle portion generally parallel with one another; and a first level attachment including a platform having the general shape of a rectangular prism, a lower portion of the platform defining a channel open on at least a bottom side thereof to receive the handle portion of the comb, side walls of the channel defining respective left and right depending flanges with engaging portions that extend inwardly into the channel to engage the first and second grooves of the comb and to mount the platform for sliding movement along the handle portion of the comb, a level housing mounted on the platform for rotation about a generally vertical axis of rotation relative to the platform, a bubble level mounted in the level housing, a geometric shape of the level housing determining a fixed, predefined angle of the bubble level with respect to the platform, the predefined angle being greater than 0° and less than 90° , and user-manipulatable rotational actuating structure disposed in the platform and coupled to the level housing to rotate the level housing about the generally vertical axis of rotation relative to the platform; and an end level attachment including an end level housing shaped to engage and removably engaged in at least one of the first and second grooves and bearing against an end tooth of the comb, and a second level fixedly mounted in the end level housing such that it is substantially perpendicular to the long axis of the handle portion.
