1,235,036. Delivering sheets. INTERNATIONAL STANDARD ELECTRIC CORP. 28 Aug., 1969 [30 Aug., 1968], No. 42816/69. Heading B8R. Documents are delivered in succession down a curved guide channel 6, Figs. 1 and 2, by rollers 11-16, intercepting a light beam to a photo-electric cell 67 to control a valve to deliver jets of air in the direction of arrows 65. Each document passes on to a frame 23 comprising bars 24-28, Figs. 1, 3 and 4, forming a grid having a curved surface which flattens as it extends downwards. The document then passes between blades 35 and a stack 64 supported by an end wall 56 to abut a cushion 61 on a plate 55, while the air from the jets, which was insufficient to blow the document off the grid while held by the rollers 15, 16, now completes the stacking movement. The pressure of the document on the blades 35 pivots the frame 23 to operate a servo-mechanism which moves the stacking means to the right along a surface 59. If a document exceeds a certain length, continued interception of the light beam operates through a delay mechanism a valve to produce air blasts in the direction of the arrow 66 to prevent folding over of the tracking edge. In the case of a document much wider than the frame 23, a further rod 29 of the latter prevents folding over of the edge of the document on the right in Fig. 4. To minimize damage to a document abutting the cushion 61 at an angle, the surface of contact with the cushion is increased by providing the plate 55 with a raised portion 60. |
