IMPROVEMENT IN MANUFACTURING ENVELOPES.

The Schedule referred tu 1n these Letters Patent and. making part of the same.,

'u au' whom it may concern Beit known that I, JAMES BALL, ofthe city, county, and State of New York, have invented a new and irnproved Sheet for Ont-ting out Envelopes; and I 'do hereby declare the following to beafnll, clear, and exac t description thereof, which will enable those skilled in the art to make and use. the same, reference being!I had to the accompanying drawing forming part of this specil'ication, which drawing represents a plan or tace view of a sheet of paper cut out according to this invention.

In cutting out envelopes-the first operation usually is to cut a roll of paper up into sheets, each sheet-large enough for sixteclu'niore or less, envelope blanks. lhe form ot' these 'sheets is'either square or diamond-shape, but in all cases known to me the edges ot' the sheets have heen rectilinear, and I have found that by cutting the 4sheets with recessed or pectinated ends or edges, a great saving ot' paper can be "'etiected.

It' the sh'eets are cut with square edges it requires under the best possible management, thirty inches in length (the width ot' the sheet being that of the roll from which the sheets are cut) for sixteen envelopeblanks Otordinary letter size, bnthycutting the sheets with pectinated or scalloped edges according to-xny invention, only twenty-seven inches in length :nerequired for sixteen envelopes of the saine s ize, and consequently a very material saving of' paper is et'- fected.v t I In the dra\ving i The letter A designates a vsheet of paper cut out with scalloped ends o b, the scallops being composed of angular'recesses formed in succession across the sheet, those ofthe edge a ,being reverse to those of the edge 71, so that no paper is wasted.

.My invention is hereillustratcd in connection with rholnbshaped blanks, and una sheet of this kind the, pattern for an envelope-blank can he so adjusted that sixteen rhon'ib-slutped envelopes can be cutont from the saine, and I llavefoniid that l can save threeinches ot' paper on cach sheet of sixteen envelopes, as compared with the old method ot cutting.

The amount of paper saved hy my invention of course varies according to the size ot' the envelopesA to be cut out, but lny experience snows that in the factory where l ain employed, and where we have cut up for successive days as much as forty-tive thousand yards of paper per dav, I have heen enabled to etl'ect a saving offour thousand live hundred vards per day, since forty thousand tive hundred yards of paper when cut according to my' invention, will produce as many envelopes as torl1y-tive thousand yards out in the old u v. v

In order to cut out niy sheets with the requisite accuracy and despatch, I have constructt-ul 'a cuttingmachine,`hy lneans of which sheets -with scalloped edges can be cut with great facility, hut lV do notre- 'strictmyselt' to any mode of forming such edges or ends ot' the sheets. vWhat I claim as new, and desire to secure hy Letters Patent, is

'lhe sheet A for envelope-blanks, formed with Vscalloped ends a and b,`thc scallops made with angular recesses in succession across the sheet, when those of the edge a are reverse to those ofthe edge Zr, substantially as herein shown and described.,
