Abstract

A pair of elongated generally parallel mounting members are provided and a plurality of laterally spaced elongated transverse guide members extend between the support members. The opposite ends of the transverse guide members and the support members include coacting clamp and guide structure supporting the guide member ends from the support members for adjustable shifting therealong. The coacting clamp and guide structure is operative to releasably anchor the guide member ends in adjusted shifted positions along the support members and each of the guide members includes an anchor post supported therefrom, shiftable longitudinally therealong and releasably anchorable in adjusted position, the posts being disposed generally normal to a plane paralleling the mounting members and guide members.

Claims

1. An apparatus operable to perform selected rod bending operations, said apparatus including a pair of generally parallel support members, a plurality of laterally spaced elongated transverse guide members extending between said support members, the opposite ends of said guide members and said support members including first coacting clamp and guide structure supporting said guide member ends from said support members for adjustable shifting therealong and operative to releasably anchor said guide member ends in adjusted shifted positions along said support members, at least one post for each guide member, said posts and guide members including second coacting clamp and guide structure supporting said posts from said guide members for adjustable shifting therealong and operative to releasably anchor said posts in adjusted shifted positions along said support members, said posts being disposed substantially normal to a plane paralleling said support members and guide members.

2. The combination of claim 1 wherein said posts include extended end portions thereof which are substantially cylindrical and support diametrically enlarged heads on their terminal ends.

3. The combination of claim 1 wherein said first coacting clamp and guide structure includes longitudinal T-shaped slots formed in said support members and threaded fasteners journaled from the ends of said guide members, projecting into said slot and threadedly engaged with threaded nuts slidably received in said slots.

4. The combination of claim 1 wherein said second coacting clamp and guide structure includes longitudinally extending T-shaped slots formed in said guide members, said posts including lower ends projecting into said slots and threadedly engaged with threaded nuts slidably received in said slots.

5. The combination of claim 4 wherein the lower ends of said posts include diametrically reduced threaded terminal ends defining downwardly facing abutment shoulders, a lock nut threaded on each of said terminal ends and upwardly abutted against the corresponding shoulders, said terminal ends being threadedly engaged in the nuts slidably received in said guide members.

6. The combination of claim 1 wherein one pair of corresponding ends of said support members are anchored relative to the opposite ends of an elongated connecting member extending therebetween.

7. The combination of claim 6 including clamp structure carried by said connecting member and overlying the guide member adjacent said connecting member and movable toward and away from the last mentioned guide member to clamp a workpiece between said last mentioned guide member and said clamp structure.

8. The combination of claim 7 wherein said posts include extended end portions thereof which are substantially cylindrical and support diametrically enlarged heads on their terminal ends.

9. The combination of claim 8 wherein said second coacting clamp and guide structure includes longitudinally extending T-shaped slots formed in said guide members, said posts including lower ends projecting into said slots and threadedly engaged with threaded nuts slidably received in said slots.

10. The combination of claim 9 wherein the lower ends of said posts include diametrically reduced threaded terminal ends defining downwardly facing abutment shoulders, a lock nut threaded on each of said terminal ends and upwardly abutted against the corresponding shoulders, said terminal ends being threadedly engaged in the nuts slidably received in said guide members.
