1986. Wright, A. P., and Wright, H. E. Feb. 8. Clamping-devices.-A sheet of paper and the design to be copied are so clamped that they remain in register while loose sheets of transfer paper of different colours are inserted between them. A multicolour drawing or design can thus readily be copied. In the apparatus shown, the sheets f, g are clamped on the board a by a rubber cord e. To release the sheets, the cord is extended by pulling apart the ends or by raising the centre by means of a tab n, as shown in Fig. 2. A strip of material i may be interposed between the cord and the sheet g.
