Abstract
A press for applying nailing plates across joints of wooden trusses and for other like usage is disclosed. A suspension harness for the press is adapted to be carried by an overhead universally movable support. The lower jaw member of the press is rockably mounted on the suspension harness with adjustment means provided to level the work-engaging jaw plates. An operator-controllable power cylinder is connected between rear arm extensions of the press jaws. The work-engaging jaw plate of the upper jaw is rockable on a transverse axis relative to adjustable plate stops. The lower jaw work-engaging plate is finely adjustable to enable the press to apply nailing plates with even pressure and with the proper degree of penetration into the work pieces and to accommodate variations in thickness of work pieces. Spring loaded guards on the lower jaw working-engaging plate prevent accidental displacement of nailing plates prior to application. Manipulating handles on the suspension harness and power cylinder enable guiding of the press by the operator in all directions.
