Abstract: 1,222,623. Feeding sheets. WERNER ZINDLER, [trading as LUMOPRINT ZINDLER K.G.]. 23 April, 1969 [27 April, 1968], No. 20782/69. Heading B8R. Copy sheets from a stack 109, Fig. 8, are separated by a friction roller 26, Figs. 2 and 8, in response to the tripping of a switch 2 by original sheets fed along a path 1 to the exposure station 102 of an electrophotographic copying machine, and fed by rollers 30, 31 to a conveyer including rollers 18, 116, conveying belts, and a guide 114, and thence to the reproduction station 108 of the machine. The feed speed of the conveyer is greater than that of the separator to avoid overlap of sheets. A change-over switch 58 actuated by the switch 2 and also by a switch 8 tripped by the copy sheets, energizes a magnet 10, Figs. 2 and 3, to release a disc 46 for 180 degrees rotation from a drive source 126, the disc having peripheral recesses 47, 98 engaging a wheel 48 on the shaft 49 of a clutch 37, 41. Rotation of the disc 46 allows a clutch 44, 45 to close, moving thereby a lever 43 to close the clutch 37, 41 and transmit drive to the roller 26 through a slip clutch including a gear-wheel 81 engaging a friction stop 83. Movement of the lever 43 also reverses the switch 58. The roller 30 is continuously driven, and rotation of the disc 46 pivots a lever 99 to allow a spring 75 to urge a wheel 35 and therewith the roller 31 into engagement with the roller 30. When the wheel 35 is again engaged by the lever 99 after 360 degrees of rotation, a flat portion of the roller 31 leaves the sheet free between the rollers. The drive to the roller 26 is disconnected by release of the clutch 37, 41 according to the shape of the clutch parts 44, 45.

Abstract: 615,495. Making boxes. DEHN, S. G. (Waldorf Paper Products Co.). July 12, 1946, No. 20934. [Class 18] A box is pressed from a precut blank, the four sides 10, 12, 24, 25 being folded up and interlocked in one operation on a former B. The blank A is placed between adjustable guides 44 with the base 11 midway between a pair of forming blocks 50. A plunger 64 presses the blank between the forming blocks 50, the chamfered edges 55 of which fold up the sides 12, 10 together with a lid flap 13 attached to the side 12 and flaps 35, 37 extending from the side 10. Simultaneously surfaces 62 of arms 61 adjustably attached to the blocks 50, fold up the sides 24, 25 and sweep inwardly extensions 26, 27, 29, 30 of the sides 10, 12. Tabs on each of these extensions engage in slits 31, 32 in the sides 24, 25, the slits 31, 32 being opened partly by members 63, which also assist in folding the by members 63, which also assist in folding the sides 24, 25, and partly by the distortion due to the forming operation. The forming blocks 50 with their arms 61 are arranged to pivot inwardly on leaf springs 47 under pressure of the plunger 64. This and the trapezoidal form of the sides 24, 25 enables the sides 10, 12 to be folded inwardly past the vertical to ensure the correct locking of the tabs in slits 31, 32. The plunger 64 has a base area less than that of the carton and a leaf spring 66 is attached to the base of the plunger to press the folds 14, 15 of the blank when the spring 66 flattens under pressure. As the plunger 64 rises, the leaf springs 47, 66 return to their normal positions, the box sides 10, 12 open out at right angles to the base 11 and the plunger 64 is withdrawn. The lid 13 may be closed after filling the box, flaps 41, 42, 17 being folded at right angles to the lid and the narrowed ends of flaps 41, 42 being engaged in the slits 31, 32, and a tab 20 on the flap 17 engaging in a slit 21 in the side 10. The flaps 35, 37 fold under the lid 13. The blank, prior to pressing may be covered with a moisture proof sheet 38 which forms a liner for the box and lid.
