Abstract: A tubing bending machine is disclosed comprising a die and cooperating shoe means, means for advancing the die toward the shoe means to bend a pipe positioned therebetween, and a hydraulic piston and cylinder assembly coupled with the shoe means for restricting the movement of the shoe means during bending of the tubing, and for returning the shoe means to a pre-bending position. A linear scale is connected to a piston rod of the piston and cylinder assembly and movable therewith relative to the cylinder of the piston and cylinder assembly. A depth of bend indicator means is adjustably positionable along the linear scale to indicate a selected desired depth of bend reading thereon. Switch means is mounted on the machine in the path of movement of said depth of bend indicator means to be contacted by said depth of bend indicator means as it moves with said linear scale and piston rod of said piston and cylinder assembly during the bending of a tube.
