Patent ID: 6964207

Claim:
A pipeline inspection device allowing a user to direct a light toward said inspection device and thereby visibly inspect for deformation of a pipeline, with said pipeline having an internal diameter generally composed of a bottom region, two side regions, and a top region, and having a horizontal diameter and a vertical diameter, comprising: a. a base portion, having a forward end and a rear end, configured to move along said bottom region of said internal diameter so that it lies on said vertical diameter; b. a vertical deflection bar, having a forward end and a rear end, oriented vertically, and being mounted to said base portion by movable means, so that said vertical deflection bar lies on said vertical diameter, with a portion of said verticle deflection bar extending outward far enough from said base portion to contact said top region of said internal diameter, and wherein said vertical deflection bar is free to move downward when said inspection device encounters a reduction in said vertical diameter of said pipeline; c. biasing means positioned to bias said verticle deflection bar upward; d. a reflector attached to said base portion and positioned so as to be visible to said user when said user shines said light on said rear end of said base portion from far away; and e. an occluding device, moveable in relation to said reflector, and connected to said vertical deflection bar so that as said vertical deflection bar moves downward, said occluding device occludes said reflector, thereby indicating to said user that a reduction in said vertical diameter of said pipeline has been encountered.
