An apparatus is selectively controlled to insert a check pin into a fastener hole in a workpiece surface and remove the check pin from the fastener hole. The apparatus is a pneumatically actuated apparatus having a pair of press actuators that are selectively operated to press the check pin attached to a check pin holder of the apparatus into a fastener hole in a workpiece, and a pair of remove actuators that are selectively operated to push against the workpiece surface and move the apparatus away from the workpiece surface to remove the check pin attached to the check pin holder from the fastener hole in the workpiece.

A pry bar assembly includes a plate that is elongated and has a first end, a second end, a first lateral edge, a second lateral edge, an upper surface and a lower surface. The plate includes a claw section, a chisel section and a middle section positioned therebetween. The claw section includes the first end and a rounded heel. The claw section includes a first portion and a second portion. The first portion is attached to the middle section and curves upwardly and away from the middle section in a semi-cylindrical shape to form the rounded heel. The second portion extends downwardly from the first portion. The chisel section is angled upwardly from the middle section. The upper surface has an elongated crest therein that is spaced from the first and second lateral edges and extends along a length of the middle section and into the chisel section.

The present disclosure is directed to a fastener driver for driving a fastener into a workpiece. The fastener driver includes a housing and a lever pivotably coupled to the housing and actuable to cause the fastener driver to drive the fastener into the workpiece. The fastener driver also includes fastener puller removably coupled to the housing and operable to remove the fastener from the workpiece. The fastener puller includes a base portion, a removal head, and a pivot region. The removal head is affixed to the base portion and configured to pry the fastener from the workpiece. The removal head has a flat shape. The pivot region is defined between the removal head and the pair of legs. The pivot region is configured to contact the workpiece such that during operation the fastener puller pivots about the pivot region relative to the workpiece.

Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

A screw bit body which allows for efficient torque force application onto a socket fastener from a variety of angles. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a concave surface, a convex surface, and an engagement cavity. The convex surface is adjacent to the first base and the concave surface is adjacent to the second base to create a ball-like shape. The engagement cavity creates a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base.

A molding removal tool assembly for prying molding off of a wall surface without damaging the molding or the wall surface. A pry bar is provided at its proximal end with a pry bar plate that extends at an angle from the pry bar and a striker shoe plate is secured with a hinge to the pry bar at and aligned with an edge of hinge securement of the pry bar plate to the pry bar. The striker shoe plate is provided with a cutout portion that receives the pry bar plate therein whereby the pry bar plate and striker plate are substantially flush with each other in a common plane when the pry bar plate is fully received in this cutout portion of the striker shoe plate. The striker shoe plate is provided with an exposed striker edge for receiving hammer blows in order to simultaneously wedge the flush striker shoe and pry bar plates between a wall surface and a molding attached to the wall surface. Once embedded, the pry bar is rotated to pry the molding away from the wall surface.

A nail puller having a lever arm assembly with an arcuate gripping jaw plate secured to a bottom end, and a base assembly pivotally secured to the bottom portion of the lever arm assembly, the base assembly includes an arcuate rocker base plate pivotally secured to a bottom portion of the lever arm assembly for concentric pivotal movement relative to the arcuate gripping jaw plate of the lever arm assembly. The arcuate gripping jaw plate of the lever arm assembly and the arcuate rocker base plate of the base assembly are provided with transverse open-ended slots for simultaneously receiving the shank of a nail to be extracted. The nail shank received within the slots is gripped and leveraged out by rotating the upper lever arm assembly in either a clockwise or counterclockwise direction.
