A material manipulation apparatus comprising, in combination,
- a first arm mounted to a second arm, including a first pivot axle pivotally mounting the first arm to the second arm in a cross configuration, wherein the first pivot axle divides the first arm as an upper first arm and a lower first arm and divides the second arm into an upper second arm and a lower second arm, and
- the lower first arm includes a first jaw arm web arranged at an acute angle to the lower first arm at a lower terminal end thereof mounting a first jaw, and the lower terminal end of the lower second arm includes second jaw arm webs arranged at an acute angle to the lower second arm mounting a second jaw, the first and second jaws arranged in confronting relationship relative to one another, and
- a first link mounted adjacent an upper terminal end of the upper first arm, including a first link rear pivot mounting a rear terminal end of the first link to the upper first arm, the first link including a first link forward terminal end, and
- a second link, including a second link forward terminal end and a second link rear terminal end, and a second link rear pivot mounting the second arm rear terminal end to the upper second arm, and the first link and the second link pivotally mounted together, including a second pivot directed adjacent the forward terminal ends of the first link and the second link, and
- wherein the second pivot includes a support ring fixedly mounted thereto, and the support ring including a support link, the support link including a lock pin to selectively secure the support link to a support mount, the support mount fixedly mounted to a lift member to effect lifting and simultaneous closure of the first jaw relative to the second jaw, and
- wherein the upper first arm includes a third link, including a third link rear pivot directed through the third link adjacent a rear terminal end of the third link and through the upper first arm between the first link rear pivot and the first pivot axle, and a fourth link, including a fourth link rear terminal end and a fourth link forward terminal end, with the fourth link rear terminal end mounted to the upper second arm intermediate the second link rear pivot and the first pivot axle, and the forward terminal end of the fourth link including a third pivot directed intermediate the third link to pivotally secure the fourth link to the third link, and
- wherein the third link includes an abutment flange fixedly mounted to the third link adjacent a forward terminal end of the third link to prevent over-centering of the third link relative to the fourth link, and
- wherein the third link is defined by a predetermined length, and wherein the fourth link is defined by a fourth link length less than the predetermined length, and
- wherein the first jaw includes a first jaw support web defined by a predetermined height, and the first jaw support web complementarily received within a "C" shaped jaw support, the "C" shaped jaw support defined by spaced flanges spaced apart the predetermined height, and the second jaw includes a second jaw support web defined by the predetermined height, the second jaw support web complementarily received within a "C" shaped jaw support, wherein the first and second jaw support webs are fixedly secured to the respective first and second jaw arm webs, and
- wherein each of the first and second jaws include a resilient first jaw grasping member and a respective second resilient jaw grasping member, and
- wherein the jaw grasping members each include resilient projections mounted orthogonally and outwardly of each forward surface of each grasping member, and each resilient projection defines a matrix of projections coextensively formed about the forward surface of each grasping member, and each resilient projection includes a threaded support shank, each threaded support shank threadedly received within a threaded bore formed within each grasping member.
