Bubble level

摘要

A bubble type level for determining the orientation of a structure, such as an elongate pipe, that includes several differently oriented bubble vials that are secured within the level body in a manner such that if the bubble vials become broken or otherwise damaged, they can be easily replaced and the level need not be discarded. The bubble type level of the invention also includes a body portion having top and bottom rails that are chamfered in a manner to automatically align the level with the longitudinal axis of the pipe when the level is connected to the side of the pipe. The level further includes a plurality of longitudinally spaced magnets that are connected to the bottom rail of the level and can be used to releasably interconnect the level with a length of ferrous pipe.

主权项

1. A level for determining the orientation of a structure comprising:
(a) a body including:
(i) a top rail having transversely spaced apart, chamfered sides;(ii) a bottom rail having transversely spaced apart, chamfered sides;(iii) first and second vial chambers, each having a threaded opening; (b) a first bubble vial disposed within said first vial chamber; (c) a second bubble vial disposed within said second vial chamber; (d) a first threaded connector receivable within said threaded opening of said first vial chamber for movement from a first position to a second position in engagement with said first bubble vial to secure said first bubble vial within said first vial chamber; and (e) a second threaded connector receivable within said threaded opening of said second vial chamber for movement from a first position to a second position in engagement with said second bubble vial to secure said second bubble vial within said second vial chamber.
