. Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . ay for the out-passing sheaf ; the drop-boardsare returned; the needle is low-ered to its position of rest; thetrip is automatically relocked;and the packing of grain for an-other sheaf is resumed. All these movements, thoughserial, are performed so quicklyas to appear simultaneous, butthe nice timing of them for avirtually perfect result has beenachieved, notwithstanding thedifficulties arising from the roughjolting of harvest-work and thenecessity of cheapness of con-struction. Figs. 13 and 14 showin some detail, from two direc-tions, the mechanism that is above the table, and that is associated with the binding Mechanism.—Fig. 15 shows the relation of the binder portion to the reaper por-tion of the machine. At the rear of the binder-table is a spring wind-board, restraining theheads of the moving grain. At the front is a hinged wind-board, adjustable by hand for con-trolling the butts of the grain, but this is often superseded by a small endless apron (Fig. 16),. Fig. 13.—Knotter—driving parts.
