THREE-SIDED SHIMABLE INDEXABLE SHEAR TIP BOOT
A one piece three-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang, a shear side and a guide side pivotally connected to a lower fixed or movable shear jaw with a shear blade side, a guide side, a distal tie plate and a recess therebetween. The tang has a front edge, side faces with apertures therethrough, a top seat, a rear seat and a bottom seat. The boot tip has a front wall seated on the tang front edge and a right sidewall with an indexing hub seated on the shear side tang face, rear seat and the top seat. A bottom wall of the boot tip is seated on the tang bottom seat forming a shear punching edge between the front wall and the bottom wall. A sidewall is connected to the tang bottom and front walls with a shearing edge between the side and bottom walls. A side plate with an indexing hub is seated on the guide side tang face, the top seat and the rear seat. The boot tip right side and side plate have matching apertures therethrough and alignable with the tang apertures to secure the boot and side plate to the tang for protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess. One or more shims are provided and insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force. An extendable boss maybe on the lower inside face of the side plate as to index and interlock with a matching indexing slot on the distal face of the bottom wall.
