Patent ID: 7240437

Claim:
A pipe sizing and alignment device for determining the placement of specific angled pipe fittings along a circular pipe comprising: a base with a top plate, a first side plate, and a second substantially similar and parallel side plate, wherein said side plates extend normally from said top plate and in a parallel planar configuration so as to form a concave linear member having a front end and a rear end; a third side plate pivotally attached to a longitudinal edge of said first side plate; a fourth side plate pivotally attached to a longitudinal edge of said second side plate; a graduated protractor plate mechanically affixed to said base such that a point of angular origin of said protractor resides substantially above a midpoint of a longitudinal axis of said base; a first laser emitting light rigidly mounted at said front end of base between said first side plate and said second side plate such that when a first coherent, collimated, laser light beam is emitted it has a linear axis parallel to said longitudinal axis of said base; an arm attached to said protractor plate by a pivot member passing through said point of angular origin so as to allow said arm to pivot about said protractor's point of angular origin while remaining adjacent and parallel to said protractor plate; and a second laser generating light mechanically affixed to said arm and adapted for emitting a second coherent, collimated, laser light beam having a linear axis parallel to a longitudinal axis of said pivotable arm; wherein, when said base is placed onto a circular pipe and said first laser light beam is shone on the destination point of said pipe, said arm may be pivoted to a desired pipefitting angle, said second laser light activated and said base slid along said pipe until said second laser light beam is shone onto the center of the source of a secondary pipe thereby indicating the proper location for a pipefitting of the desired angle.
