Valuable Safety Attachment to Guillotine Machines.—

Mr Upcott Gill, publisher, and proprietor of the Bazaar, has invented an attachment for guillotines, not the least important feature of which is that it insures perfect safety to the operator, and thereby enables a higher rate of speed to be obtained than ever before. A sixty-four-page pamphlet, trimmed two sides, can be turned out at the rate of nearly 8,000 an hour. A machine, worked by one man, could trim ordinary newspapers—one cut, at the rate of nearly 50,000 an hour; two cuts, 30,000. Not only can the amount to be trimmed off be readily and accurately adjusted; but the gauge may be automatically changed as required every second, third, or fourth cut. Thus the three cuts, head, tail, and fore-edge, may be taken for each single pile, without the slightest loss of time at the machine, and with an economy and amount of convenience in all other respects which every practical man will appreciate.—The invention is intended for edge-trimming alone; but Mr Gill has invented an equally important attachment for sheet-cutting, in the shape of an improved cutting-bar, by means of which the last sheet is always cut as clean and true as the top one, without any underpacking.
