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.

A spike puller apparatus comprises a subframe, a pair of opposed puller arms for engaging with spikes to be pulled via a replaceable puller tool mounted on the end of each puller arm, a pair of horizontal shafts and an actuator to selectively translate each puller arm with respect to one another, an actuator to articulate each respective puller arm for pulling spikes, an A-frame connected to the subframe to resist and/or apply pulling forces to a spike being pulled, and a vertical actuator connected to the A-frame to cause the vertical slide carrier to move up and down along the pair of vertical shafts to effect a spike pulling operation. The respective puller arms are independently controllable, and may be selectively staggered with respect to one another along a rail to allow selective independent and/or simultaneous pulling of rail spikes and/or anchor spikes on opposite sides of the rail.

A spike claw puller for pulling a rail spike includes a handle that defines a through hole that is hole configured to couple to a rail spike pulling machine. A body section defines a top surface and comprises first and second feeder teeth that extend from the handle at a first lift and form a jaw opening therebetween configured to receive the rail spike. First and second feeder extensions extend from the first and second feeder teeth, where the first and second feeder extensions extend beyond a plane that is coplanar with the top surface. The first and second feeder extensions facilitate alignment with the rail spike.

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 device functioning as a stapler. The device including a viewing region within an arm of the stapler. The viewing region adapted to provide a user of the device with a view of an interior of a magazine within the arm of the stapler, wherein a user of the device can determine the amount of staples within the magazine without having to open the device. The device further includes an integrated staple removal tool received within a base portion of the device.
