ABSTRACT:
A portable press device for repairing truss joints includes jaw members spaced opposite each other having first and second end portions. A mechanism interconnects the jaw members for relative pivotal movement therebetween. A pair of plate members are disposed at the first end portions of the jaw members with the plate members facing opposite each other for receiving a truss joint therebetween. A lever arrangement is disposed at the second end portions of the jaw members to control the relative pivotal movement of the jaw members. Finally, a drive mechanism is secured to the lever members to selectively move the second end portions of the jaw members to both close and open the jaw members.
