摘要：507,034. Apparatus for finishing boxes. MULLER, J. C. Oct. 4, 1938, No. 28778.Convention date, March 18. [Class 18] Boxes with hinged lids are thrust intermittentlyalong a table with their lids open, the lid of one box is swung up out of the plane of thetable and, whilst in this position, pressure is exerted on the outside of the lid walls tobend them inwards slightly to facilitate the subsequent closing down of the lid. The tablecomprises rails 13, 14 with guides 16 ... 18 for the bodies of the boxes, and the lid of thebox being operated on rests on a pivoted plate 19 which is tilted by a forked lever 21straddling the main driving shaft 23 and carrying a roller resting on a cam plate on thatshaft. The front flange of the lid is pressed in by a curved pad 9 on a pivoted lever 47which carries a roller resting against a cam plate on the shaft 23. Two other pivotedlevers 27, 34 are actuated by cam plates on this shaft and act in the following sequence.Both levers are lowered and lever 34 alone is then raised so that a wedge 33 carriedthereby is withdrawn from between spring-pressed arms 11, 12 pivoted on a cross-shaft26 on lever 27 to allow the lower ends of the arms to press together the walls of thebody and lid which are hinged together. As the lever 34 rises, hooks 45 thereon engage

the upper ends of pivoted levers 8 connected to the shaft 26, and the lower ends ofthese levers press inwardly against the side walls of the lid against the action of springs42. The presser pads attached to lever 8, 47 have curved contacting surfaces.
