Abstract: A die pin retainer subassembly for use in a die assembly that slidably engages with a die punching machine comprises an elongated retainer, which includes at least one hole for receiving a die pin, and an elongated retaining bar disposed over the enlarged head of the die pin. At least one of the retainers on the retaining bar is in the form of a channel and the retainer and the retaining bar are sized and configured to nest along the lateral direction to minimize any relative lateral movement.

Abstract: The automated machine includes exchangeable spacing assemblies from which the positions of the various rollers, as well as the curve of the perforations in the stack(s) of sheets are determined for a spiraling a given coil size into the stack of sheets. Various sizes of spacing assemblies are provided to allow the operator to the binding machine to bind various sizes of coils into a stack of sheets by exchanging the spacing assemblies. Two support surfaces support the halves of thick books, the coil spiraling through stacks of sheets positioned on both support surfaces simultaneously. The stack(s) of sheets with a coil inserted therethrough drops to a crimping station when the rollers separate and the support surfaces pivot toward a vertical position. Once the crimping operation has been performed, an ejector ejects the book from the crimping station, and book exits the machine under the force of gravity.

Abstract: A portable easel with adjustable board support which has a plurality of legs pivotally joined together by a head, the legs of which may be selectively spread apart when set up as an easel and folded together when collapsed, each leg composed of multiple interlocked sections biased together when in extended position but which may be manipulated for separation and folding into a bundle one section against another section for storage and transport, and a board support mounted on at least one leg which may be selectively adjustably moved to a desired position on any of the sections and moved against the leg on which it is mounted for storage and transport and extended away from the leg for holding a display on the easel when set up.

Abstract: The present invention provides new paper shredding devices mountable on various horizontal and vertical surfaces. The paper shredder has a housing defining a paper inlet and a shredding knife in the housing positioned downstream of the paper inlet. A shredding knife controller is connected to the shredding knife. A shredded paper receptacle is positioned downstream of the shredding knife. A bottom of the housing serves as a tabletop mount for standing the shredder on a tabletop. One or more holes may be provided in the back side of the housing to permit the shredder to be mounted on a wall.

Abstract: The present invention provides document shredding devices mountable on various waste receptacles for shredding paper. The document shredding devices have a housing defining a paper shredding passageway. A paper shredding mechanism is contained within the housing and extends into the paper shredding passageway. A mounting support adjustably extends from a waste receptacle mounting side of the housing while remaining housing sides are free of waste receptacle mounting supports. The mounting support has a position retracted into the housing which defines a substantially linear mounting channel and another position extended outward from the housing which defines a nonlinear mounting channel.

Abstract: The present invention provides new offsetting paper stacking devices and methods which automatically stack sheets of paper into groups which are offset from each other. The offsetting paper stacker stacks sheets of paper that are feed into an input end of the device one at a time at a high rate of speed. The paper is stacked in one pile, however, within that pile there are groups of sheets that are stacked at a sideways offset to the group immediately above and below. Accordingly, every other group of sheets of paper will be in line with each other and each adjacent group will be offset from each other. The offsetting paper stacker includes stacker wheels which are rotatable about two axes of rotation to stack the paper in an offset manner.

Abstract: A personal binding machine for assembling a preformed coil into a stack of prepunched sheets which includes a loading tube assembly that properly orients the coil to be driven into the stack of sheets, a drive assembly which drives the coil into the stack of sheets, and crimping assemblies for crimping the ends of the coil once inserted into the sheets. The drive assembly includes a three surface contact system having a coil guide substantially adjacent the edge of the stack of sheets, a drive roller and an idler roller. While the coil guide is stationary within the housing, the location of the drive and idler rollers may be adjusted via a camming system to accommodate various coil sizes. The crimping assemblies include a cradle and blade mechanism wherein the blade presses an end of the coil into a cradle to bend or crimp the end. The drive roller may alternately be directly accessed to manually drive the coil through a stack of sheets.
