in clamping engagement directly with conduit 12 when the roller assembly 21 is rotated to bend conduit 12 in turn the metal rollers 28 and 29 as with metal rollers 24 ride on the respective rims 25 of shoe 1 as the roller assembly 21 is rotated the rotation of roller assembly 21 is accomplished by operation of the hydraulic motor 18 which actuates piston rod 19 connected to the roller clamping assembly 21 by the captive pin 22 when the conduit 12 is initially loaded into the bender it is necessary that the inner end portion be clamped to shoe 1 this is accomplished by a u shaped saddle 32 which extends over conduit 12 and is secured to shoe 1 by the readily removable pin 33 which extends through the legs of saddle 32 and through shoe 1 turning now to fig9 and 10 for purposes of illustration there is shown the bending of thin wall electrical tubing or conduit 34 having a nominal diameter of one and one half inches in order to accomplish the bending of conduit 34 it is necessary to disassemble the conduit bending apparatus in a similar manner as described in detail in u s pat no 3 987 656 in general this involves lifting off top frame member 14 and the top plate sub assembly of roller assembly 21 which sub assembly consists of top plate 20 affixed axle pin 20b and large metal roller 26 rollingly attached to its axle such as by a snap ring 26a saddle 32 has been already removed when the bending of conduit.
