A manually operable spreader which can be moved from behind on a surface is especially suitable for distributing salt and other particulate materials which tend to conglomerate or clump in a hopper of the spreader. Wheels are mounted to a frame also support the hopper. A horizontal drive shaft between the wheels is coupled to rotate a vertical shaft. A distributor below the hopper rotates with vertical shaft rotation to distribute particulate material which drop via openings in the bottom of the hopper. The vertical shaft extends via a hole in bottom of hopper and carries at the top thereof an auger having a helical vane. The auger is rotatable with the vertical shaft as the spreader is moved on its wheels. The auger circulates the particulate material in the hopper as the spreader moves while directing material in the hopper towards the bottom thereof.

Manually operable push from behind spreader

A closure for attachment to a centrifuge bottle. The closure comprises an end wall and a sidewall extending from the end wall. The sidewall comprises a first terminal end, a second terminal end, a first transition surface, and a second transition surface. The first terminal end has a first outer peripheral boundary at a first radial distance from an axial centerline. The second terminal end has a second outer peripheral boundary at a second radial distance from the axial centerline. The second radial distance is less than the first radial distance. The first transition surface extends between the first outer peripheral boundary and the second transition surface. The second transition surface extends between the first transition surface and the second outer peripheral boundary.

Centrifuge bottle closure and assembly thereof

A justification apparatus, which receives cut sheets of different widths along a path in an in-track direction of travel, aligns the sheets relative to an in-track axis. The apparatus includes a tray having a planar surface for receiving unconstrained sheets. An edge abutment is movable in opposed directions parallel to the plane of the tray surface so as to contact a side edge of a sheet received on the surface to move the sheet with the edge abutment. The edge abutment is sequentially movable (i) away from the in-track axis to a position spaced from the in-track axis a distance sufficient to allow loading a first sheet of predetermined width onto the tray surface with more than half of the width of the first sheet between the in-track axis and the edge abutment, (ii) toward the in-track axis to a position spaced from the in-track axis by a first predetermined distance so as to effect cross-track directional and skew alignment of the first sheet to the in-track axis, and (iii) away from the in-track axis to a position spaced from the in-track axis by a distance sufficient to allow loading a second cut sheet of predetermined width onto the tray surface with at least half of the width of the second sheet between the in-track axis and the edge abutment, the predetermined width of the second sheet being different from the predetermined width of the first cut sheet, and (iv) toward the in-track axis to a position spaced from the in-track axis by a second predetermined distance so as to effect cross-track and skew alignment of the second sheet to the center line, the second predetermined distance being different from the first predetermined distance by approximately one half the predetermined width of the difference between the width of the first cut sheet and the width of the second sheet.

Cross-track and skew justification of cut sheets

Apparatus for advancing the cut sheets in an in-track direction to a sheet justification apparatus includes a driven roller and a gimbaled, self-aligning follower associated with the driven roller. The follower is movable between an engaged position, forming a nip with the driven roller, and a disengaged position, spaced from the driven roller. The follower is selectively movable to its engaged position to direct media from to the justification mechanism, to its disengaged position to allow the justification mechanism to justify the sheet, and back to its engaged position without introducing skew or shift as it re-engages the media to direct media from the justification mechanism without introducing skew or linear shift. The driven roller and the follower may be associated such that the media forms a wrap angle partially around the roller. The follower has a degree of freedom to rotate about an axis aligned with the direction of movement of the follower between its engaged position and its disengaged position. The follower is bi-directional, having a pair of rollers, one roller on one side of the axis in the direction of media travel and the other roller on the other side of the axis in the direction of media travel. The follower has a second and a third degree of freedom to rotate about a pair of orthogonal axes that are in a plane perpendicular to the axis aligned with the direction of movement of the follower.
