Abstract: 476,522. Feeding sheets. CROWN CORK & SEAL CO., Inc. June 9, 1936, No. 32786. Convention date, June 10, 1935. Divided out of 476,502. [Class 100 (i)] In a sheet-feeding apparatus mechanism is provided for returning sheets to a stack 51 should more than one sheet be fed at a time consisting of a movable stripper device in the form of one or more bars 185 which are moved across the underside of the separated sheet when this reaches the sheet-forwarding rolls 66, 64. Excess sheets are thus returned over the gauge bar 61 against which the pile 51 is registered. The invention is described as applied to a sheet-feeding machine as described in Specifications 476,502 and 476,503, and the bars 185 are moved by means of eccentrics 188, which engage straps 187 fixed to the bars, in such a way that the upper portions of the bars move in an elliptical path as indicated in Fig. 4, and during the portion of the movement represented by the upper part of the ellipse, the bars contact with the sheet being fed and return excess sheets to the pile. The upper parts of the bars 185 are formed with offset parts 62 which co-operate with slots in the gauge 61, and the lower parts of the bars are bent at 191 and pass under brackets 192 fitted with screws 193 which serve as pivot points for the bars. By adjustment of these screws the movement of the lower ends of the bars is regulated. A bracket 194 attached to each gauge plate guides the outward swinging movements of the bars 185.
