Abstract: A container fastener system which facilitates construction and use of containers formed of tri-wall or other multi-layer corrugated paper board is disclosed. Plate and clip fastening systems particularly adapted for interconnection of panels in overlapping relationship are disclosed. The arrangement facilitates adhesive attachment of the plate components to the panels and the attachment and interconnection of the plate components by clip members without penetration of the surfaces of the panels. One plate component of each pair is provided with a retainer flange which prevents lateral separation of one panel with respect to the other so as to maintain the integrity of the container when the panels are fastened together.

Abstract: Modular system for making containers, including reusable panels for the side walls of the containers, the side wall panels having horizontal edge portions providing for guided vertical stacking of the panels, the side wall panels also having fastening devices adjacent the upright corners of the containers, with the end portions of the panels overlapping each other in a series in one direction around the perimeter of the containers, and with fastening devices including fastening plates in a series overlapping each other in the opposite direction around the perimeter of the containers.

Abstract: System for interconnecting panels, especially adapted for use in the temporary interconnection of panes of cartons or containers used for shipping or transportation, the arrangement is particularly adapted to the interconnection of panels in edge-to-edge relation where the panels either lie in the same plane or lie in planes extended at angles to each other particularly in a range between the 180 degrees of the common plane relationship and the 90 degree relationship at the corners of common rectangular cartons.

Abstract: A lever operated mechanism for dispensing paper toweling, particularly from a transfer type of towel dispenser for sequentially delivering toweling from a primary roll in a first station and from a secondary roll in a second station and including a two-way actuable lever and a toothed rack movable in opposite directions by the lever and meshing with the teeth of a drive gear which is shiftably mounted, thereby providing for feed of the toweling upon movement of the lever in either direction, without the necessity for employment of clutches.

Abstract: A transfer towel dispenser for sequentially delivering toweling from a primary roll in a first station and from a secondary roll in a second station, provision being made for mounting the primary roll in the first station with freedom for shifting movement, and including transfer mechanism for transferring the web fed from the primary roll to the secondary roll, the transfer mechanism being connected with the shiftable mount for the primary roll and triggered by shifting movement of the primary roll and its support upon exhaustion of the web being delivered from the primary roll.

Abstract: A fastening system for structures such as knock-down crates and other multiple panel structures is disclosed. Resilient spring clips prebent to form two angularly disposed arms are provided for releasably locking panels such as the rectangular sides, ends, tops, and base panels of a knock-down shipping container. Each clip has a bent over end on one arm forming a hook adapted to fit into and to be held within a retaining slot in a bracket carried on one panel and further has a detent formed at the end of the other arm adapted to fit within an opening in a bracket on the adjacent panel to resiliently lock the panels in place when the clip is flexed.
