Auto body crushing device

A crusher assembly for compressing automobile bodies and the like for attachment to the boom structure and hydraulic system of a mobile power source and the like, comprising:

• a. a rigid elongate frame having a first end portion,
• b. securing means for attachment of the frame to the boom structure and hydraulic system of the mobile power source,
• c. a panel shaped fixed jaw having an exterior confronting surface, the fixed jaw having a proximal end affixed to the first end portion of the frame and extending therefrom, the fixed jaw also having a distal end remote from the frame, and the fixed jaw having side ends between its distal and proximal ends,
• d. a panel shaped operable jaw, having an exterior confronting surface, the operable jaw having a proximal end adjacent to the frame and extending therefrom the a distal end of the operable jaw, the operable jaw also having side ends between the proximal end and distal end, and including linkage means pivotally connecting the operable jaw to the frame so that the operable jaw is suspended therefrom and so that the confronting surface of the movable jaw faces the confronting surface of the fixed jaw, the linkage providing for swinging of the operable jaw toward and away from the fixed jaw and providing for maintaining the exterior confronting surface of the fixed jaw in a substantially parallel relationship with the exterior confronting surface of the operable jaw during movement of the operable jaw, and
• e. drive means connected to the linkage means for operating the operable jaw.

A crusher assembly for compressing automobile bodies and the like for releasable attachment to the boom structure and hydraulic system of a mobile power source and the like, comprising:

• a. a rigid elongate frame, having a first end, a second end and a middle portion therebetween,
• b. an adjustable securing member pivotally secured on one end to the boom structure and hydraulic system of the mobile power source and on its other end pivotally secured to the middle portion of the frame,
• c. a panel shaped fixed jaw, having an exterior confronting surface, the fixed jaw having a top end secured to and integral with the first end of the frame and depending therefrom to a bottom end of the fixed jaw, and the fixed jaw having side ends between its bottom and top ends,
• d. a panel shaped operable jaw, having an exterior confronting surface, the operable jaw having a top end adjacent to the frame and depending downwardly therefrom to a bottom end of the operable jaw and the operable jaw having side ends between the top end and bottom end, and the operable jaw connected to the frame by a linkage means, the linkage means including a first pair of links pivotally secured on one end to the frame at the middle portion thereof and on their other ends pivotally secured to a central portion of the operable jaw, and a second pair of links each pivotally secured on one end to opposite sides of the operable jaw at equivalent positions thereon and the opposite ends of the second pair of links each pivotally secured to equivalent positions on the exterior surface of the middle portion of the frame so that the operable jaw is suspended therefrom and so that the confronting surface of the movable jaw is facing the confronting surface of the fixed jaw, the linkage means providing for swinging of the operable jaw towards and away from the fixed jaw and providing for maintaining the exterior confronting surface of the fixed jaw in a substantially parallel relationship with the exterior confronting surface of the operable jaw, during movement of the operable jaw, and the operable jaw and fixed jaw when spaced apart defining an opening therebetween the opening being unobstructed along the bottom ends of the jaws opposite the frame and unobstructed along the sides of the jaws between the bottom ends thereof and the frame so that the jaws can be lowered to confront either side of the automobile body and so that the jaws can be positioned along the automobile body, and
• e. a driving hydraulic cylinder pivotally secured on one end to the second end of the frame and the other end of the driving hydraulic cylinder pivotally secured to the first links at a point therealong adjacent the point of connection of the first links to the frame and the first and second pair of links sized with respect to the fixed jaw and operable jaw so that the amount of movement of the operable jaw is maximized with respect to the amount of extension of the driving hydraulic cylinder.
