JOSEPH N. FOUNTAIN, OF WESTFIEIIIVD MASSACHUSETTS, ASSIGEOR TO OLD COLONY ENVELOPE COMPANY, OEWESTFIELD, MASSACHUSETTS, A CORPORATION OF MAS- DECKLING ivrncnmn;

" Ap ea -i... filed. August, 19, 1925. Serial No. 1,256.

This invention relates to improvements in 5 paper, card, bristol board, or the like.

It is commonrpractice to deckle the edges of paper during the manufacture thereof but this entails considerable expense in the manufacturing cost, and tends to retard the speed of production of the paper. Finished paper has also been deckled by various means, more particularly, as by agrinding wheel but this method is'objectionable since the grinding action tends to rapidly wear the wheel which then ceases to give the desired deckled appearance that corresponds to the :deckle produced in the manufacture of the paper.

According to my invention I am able to produce the desired results by "the provision of rotary cutting tools of novel form that are so disposed with'respect to the edge of the paper that they act upon the paper with a shearing cut and tend, during the cutting action, to exert a pulling strain upon the paper in opposite. directions.

7 I have found that various grades or kinds of paper require different deckled effects and according to one feature of the invention, I have provided a cutting tool holder that is adjustable so that according to the tool v employed, it may be adjusted to position the axis of the tool so that it will operate on the paper with the desired, shearing and pulling action. v I

Other novel features will be apparent from the following description of the invention which, in the form at present preferred, is illustrated by meansof the. accompanying drawings in which Y. I V

Fig. 1 is a plan View of the machine .7 Fig. 2 is a sectional elevationalviewtaken on the line 2 2 of Fig. 1, showing the cutting tool .holder and driving means therefor V Fig. '3 is a sectional elevational view taken on the line 33 of Fig.1, showing the cutting tool and support for the web of paper.

In describing'the novel features of my invention, it will be understood that the ma chine may be adaptedifor use with other material than paper or cardboard and that any reference to such material is only intended to assist in an explanation and an under-' stand ng Of 'the structure.

A table 1 for supporting a web of material such as paper, is provided that is inthe form ofa flat plate member secured to and supported by standards or legs 2. Guides 3, forguidinga web of paper through the machine, preferably, consist of flat plates disane;

posed ina, vertical position-and are guided on the table by tongues or slides 4. fitting between guideways 5 secured to the table,

These guides are movable Qtowards and away from one another and'are held 1n various positions of adjustment by clam-ping screws 6. The-standards or legs 2 are held in a rigid spaced relation by suitable tie rods7 and preferably extend forwardly of-the supporting plate and havesecured thereto cross bars 7' on which are fixed a plurality-of spaced bars 8 and side guides 8 which form a receiving table for the sheets as they are fed from the feed, table and through the deckling mechanism soon to be described. This table may, of course,-'take any form desired and is preferably arranged to incline downwardly from the table 1.

Shafts 9 and 9', rotatable in suitable bearings 10 of the supports 2,'have fixed thereon coacting feed rolls 11 and intermeshing gears 12. The shaft 9 is provided with a driving pulley 13 whereb a rotary motion, imparted to the pulley, wi ljcause the rolls to operate in unison to grip therebetweena sheet or web of paper and feed it forwardly through the deckling mechanism and onto the delivery table. The pulley1'13 be driven from any suitable source of 'power and at. any

speed desired or'lit may be belted to any of the well knownvariable speeddriving devices so that the speed may be varied from timefto time.

Arod 14 extends across thejtable which is d r 95 supported in brackets15 and carries a plurality oflfriction devices,',preferably in the form of brushes .16, which are adapted to bear upon the paper as it is fed forwardly by the feed rolls11 and tends to maintain the paperrin a'lflat condition. Guide members l'l'fixed to the rodltextend forwardly thereof and have their forward ends'disposed beneath other-guidesr18 fixedto the,

These 'guidesfa-re preferably ar-' guides '3. ranged to guide the paperj'as it lsjfed' foracted upon 'by the cutting mechanism. I

I 'wardly and to vprevent' it. buckling when Silpp rt n -p at s are se u ed at ther end in screw threaded engagement with the post 22 by themeans of which the tool hold er may be raised or lowered to various positions of adjustment. An index dial 28 fixed on the screw carries designating markings which may be registered with a pointer 29-located in an opening 30 in the side of the standard by the means of which, settings of the holder may be duplicated as may bedesired. I

The holder '23 has av shaft 24 rotatable therein that is provided with a tool holding chuck 25 of usual form at its forward end and a driving pinion 2'6 fixed to its rearward end. A motor M atop of the holder has a driving gear 27 fixed to the shaft thereof that is in meshing engagement with the pinion 26 for. driving the shaft 24".

A tool T preferably in the form of a milling'cutter having peripheral cutting teeth disposed longitudinally thereof, is clamped in the chuck 25 and is preferably disposed so as to overlie apaper supporting member 29" that is carried byan arm 30 extending upwardly from the'standard 21. This mem ber 29is arranged to engage the underside of the paper to support the same against the action of the cutter and may take any form desired, that shown being a disc that is secured to the arm by a screw 31. It is not necessarily rotatable on the screw '31v but may be fixed rigidly and moved about its axis to present new supporting surfaces should the tool cut or injure it.

The cutting teeth of the cutting tool may take any of the usual forms, thatishown being of the spiral type which has been found preferable for certain kinds of paper, while straight teeth or nearly so, may be more advantageously employed for other kinds.

As will be'noted, the tool holder may be adjusted vertically to accommodate different thicknesses of paper. or to create various deckle effects and that it is rotatable so that according to the type of tool employech'the tool may be disposed at various angles with respect to the edges of thepaper whereby it will operate thereagainst with a shearing action as is desirable to produce the most perfectdeckle edge effect.

Regardless of theparticular form of cutting tools employed,'it is .possibleto so position them with respect to the edge of the paper that their cutting teeth will, when operating on the paper, exert a pulling action,that is, while the cutters are'acting upon opposite edges of the paper they will also tend topull the paper in opposite di- Ti rections to flatten the paper for the shearing cut and thereby assist the cutting operation so that the finest possible cuts may be made to produce the desired fine quality deckle edge.
