I shall begin with first describing the prin-cipal working parts of the machine. Tworiggers, A, are driven from below off oneof the engine-woolers; and on the shaftthere is a sliding clutch-box with a lever,marked B, for instantly stopping or startingthe machine. From one of the riggers astrap proceeds, which sets in motion the 50 P>/.// r Iiougd >::; cud damping rigger C, with a fly-wheel and arm D, whichbeing connected with the head with theknife, or cutter, E, causes it to shde alongthe bar F, which is of a triangular form, asrepresented in the section F. G is a handle,by turning which, with the help of two pairof mitre wheels, fixed on a shaft, and thevertical screws attached to the bar F, theknife, bar, &c. is made to descend. Themode of operating is as follows: On the ma-chine table or platform, we place each reamon its beech-board, for the ploughing knifeE to cut down to. We then lay on a sheet-brass gauge plate, and mark off with a pencilhow much of the three external sides are tobe cut away. The paper ia then put on the machine, which has a sort of parallel rulerback, worked by two pinions and racks. Thehandle H is now turned towards the work-man, and the pencil mark brought level withthe front of a double iron straight-edge. Thelower edge is fixed firm and level with thetable ; and at each end there is a IJ inchcylindrical pin cu
