Multiple Tool Attachment System

Abstract

A multiple tool attachment system is adapted to be attached to demolition equipment. The system includes a universal body attached to the demolition equipment. A series of tools is independently attachable to the universal body. The universal body includes a guide slot extending longitudinally along the universal body. Each tool generally includes a pair of pivotable jaws adapted to be pivotably attached to the universal body with at least one linkage extending from the universal body and attachable to each jaw of the tool. A slide member is received within the guide slot, with each linkage attached to the slide member, and a piston cylinder arrangement is attached to the universal body and coupled to the slide member for moving the slide member and the jaws. The multiple tool attachment system is provided with quick change features and is designed to optimize the cutting characteristics throughout the movement cycle.

1 . (canceled) 
     
     
         2 . A demolition tool comprising:
 a universal body adapted to be attached to demolition equipment, wherein the universal body has a longitudinal axis and includes a guide slot extending along the longitudinal axis;   a pair of blades pivotably attached together and removably attached to the universal body;   a linkage attached to each blade;   a slide member received within the guide slot, with each linkage attached to the slide member; and   a piston cylinder arrangement attached at one end to the universal body and attached at the other end to the slide member for moving the slide member, which then moves the blades, wherein the piston cylinder arrangement is attached such that a piston rod of the piston cylinder arrangement is co-axial with the longitudinal axis.   
     
     
         3 . The demolition tool according to  claim 2 , further including an assembly coupling the pair of pivotable blades to the universal body and a bridge housing surrounding the main pin and detachably connected to the universal body. 
     
     
         4 . The demolition tool according to  claim 2 , wherein the piston cylinder arrangement is a combined hydraulic cylinder and rotary joint. 
     
     
         5 . The demolition tool according to  claim 4 , wherein the combined hydraulic cylinder and rotary joint includes a rotatable cylinder housing, a rotatable cylinder extension extending from the cylinder housing, and a stationary housing surrounding the cylinder extension. 
     
     
         6 . The demolition tool according to  claim 2 , wherein each blade includes a plurality of removable inserts. 
     
     
         7 . The demolition tool according to  claim 2 , further including a rotary coupling in the universal body providing for 360 degree rotation of the pair of blades. 
     
     
         8 . A demolition tool adapted to be attached to demolition equipment, the tool comprising:
 a universal body adapted to be attached to the demolition equipment, wherein the universal body includes a guide slot extending along a longitudinal axis of the universal body;   a pair of blades pivotably attached to the universal body;   a separate linkage attached to each blade;   a slide member received within the guide slot of the universal body, wherein each linkage is attached to the slide member at a common pin along a single axis; and   a piston cylinder arrangement attached to the universal body and coupled to the slide member for moving the slide member and the blades, wherein the piston cylinder arrangement has a piston with a longitudinal axis co-axial with the longitudinal axis of the universal body.
