Adjustable Angle Stop for Bending Conduit
20220288664 · 2022-09-15 ·

An adjustable angle stop for bending conduit. The adjustable angle stop generally includes an elongated body comprising a first end and a second end and a stop element at the first end, and an inner surface on the elongated body adapted to engage a conduit. The elongated body may also include a plurality of indexing elements usable to position the angle stop on the conduit, the indexing elements indicating a bend angle. One or more magnets can removably attach the elongated body to the conduit, wherein the adjustable angle stop will contact a part of a bending tool indicative of a predetermined bend angle when the bend angle is reached.

Tube bending apparatus and method

A bending wheel of a tube bending apparatus includes a tube-accepting recess, proximal and distal wheel faces, and a rotation recess. The proximal wheel face includes a lever pivot anchor. A cam insert includes a shaft having a tool driving feature. The shaft is configured for selective insertion into the rotation recess. The cam insert includes a camming flange, which includes a lever urging feature. A keeper lever includes a keeper finger rigidly connected to a laterally extending lever arm and extending longitudinally from the proximal wheel face. An anchor end of the lever arm includes an arm pivot feature and a spaced-apart cam following feature configured to interact with the lever urging feature. Rotation of the cam insert causes rotation of the lever urging feature to drive the cam following feature of the keeper lever and pivot the lever arm in the same rotational direction.
