ABSTRACT:
Conduit bending apparatus embodying a bending unit having a movable shoe spaced from conduit engaging members. The bending unit is pivotally connected to an upstanding member which is carried by an elongated guide. Resilient means holds the upstanding member at selected elevations relative to the guide member. Elongated end members are pivoted to end portions of the guide members and depend therefrom for angular movement to selected positions relative to the guide member. An elongated conduit support member extends between and is pivotally connected to the end members to support a conduit at selected elevations in response to angular movement of the end members.
