US 5,154,000 A · Conduit bending plane and bend angle indicator

Abstract

A conduit bending plane and bend angle indicator having a clamp mounting, an anti-dog bubble level to indicate the bend of plane, and an angle bubble level to indicate the bend angle. The invention further features a ratchet connection between the anti-dog bubble level and the clamp mounting to enable the anti-dog bubble level to be referenced at level without having to rotate the conduit to level. A second ratchet connection is also provided which allows the angle bubble level to be set plumb so as to accurately indicate the bend angle without having a first level the conduit along its longitudinal axis. Thus, the disclosed invention provides a quick and easy device to indicate the bending plane and bend angle of conduit being bent without requiring additional adjustments to the conduit once the device is mounted to it.

Dependent claims

A device for indicating the bending plane and the angle of a bend of a piece of conduit comprising:

a mounting section having means for attaching the device to a piece of conduit so that a longitudinal axis of the device corresponds to a longitudinal axis of the conduit;
an anti-dog section having plane indicating means which indicate that a bend in the conduit is essentially coplanar with the longitudinal axis of the conduit;
means for attaching the anti-dog section to the mounting section for rotation about the longitudinal axis of the conduit permitting the anti-dog section to be set to a horizontally level position without having to first level the conduit along its longitudinal axis;
an angle indicating section having angle indicating means which indicate the angle of a bend in the conduit;
and
means for attaching the angle indicating section to the anti-dog section and permitting rotation about the horizontal orthogonal axis of the conduit to allow the angle indicating section to be set to a level position without having to first level the conduit along the longitudinal axis of the conduit.
