Specification of Letters Patent.

Patent ed Nov. 14, 1911.

Application filed March '29, 1910. Serial No. 552,196.

To all whom it may concern:

Be it known that I, J osnrn W. Moonn, a citizen of the United States, and'resident of Newton Highlands, in the county of Middlesex and State of Massachusetts, have in vented an Improvement in Machines for Making Deckle and Thin Edged Paper, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

For various purposes, such as book-binders use, paper-tube winding, and various other places where it 1s desired to make an exceedingly tight, neat joint or pasted edge, it is desirable to have the ed e of the pa per thin or beveled, and pre erably rough edged,-so-called deckle edge. The process usually followed in getting the paper into this condition is to laboriously treat it to that end during the process of manufacture atvthe paper mill, thereby not only entailing some expense but considerably reducinglthe output or speed of manufacture, and hence indirectly makingthe paper expensive.

Accordingly my invention has for its ob: ject the provlsion of a machine for treating any paper which may be bought in the market, so as to produce the desired kind of an edge. The paper is simply passed through the machine, and the machine has provision for adjusting it so .as to accommodatevarious widths and kinds. of paper and so as to produce a thin-edge at practically any bevel desired, besides produclng @IllllfOlH). bevel and such deckle edge as may be desired. -To

. this end, I provide preferably means for tru- 3 also contains means whereby if desired only f 1 plate 34 which is given a lateral movement ing the edge of the paperbefore it reaches the beveling device, andthen I'maintain the edge taut or under tension at the spot or region where it is being beveled, whereby all g tendency of the paper to kink or pucker, and

hence defeat the object in view, is prevented and at the same time the work is greatly facilitated. p

In its preferred embodiment, my machine- In the accompan ing drawings, in which I.

have shown a. pre erred embodiment of the 1 invention, Figure 1 "represents the machine in side elevation; and F g. 2 is a view thereof in top plan.

It will be understood that I have not undertaken herein to shot I the machine in all. its minute details, nor, in fact, to show more than is necessary to con vey clearly the main features of my inventic n so far as its novel points are concerned.

J ournaled in uprigl ts 1 of a suitable frame 2 is a feed drum 3, preferably metal, around which a web 4 )f paper is led from a roll 5 supported in s ny suitable manner,

as in a stand 6, said pa per passing'between truing devices or edge utters 7 mounted on a bracket or rear bed piece 8 and adjustable at 9 widthwise of the n ,achine, the shaft 10 which carries the 11 per cutters being preferably provided with te1sion rolls 11 for insuring accuracy of-feed -At the front of the nachine, on a horizontal bed plate 12, are mounted opposite stands 13 in whose heads 14 are journaled horizontal shafts 15 dr ven by fast pulleys 16 and belt 17 from a 001 inter-shaft 18. This counter-shaft also preferably serves to drive the feed-drum 3 by me: .ns of a belt 19 and pulley 20. On the inne 2 ends of the shafts 15 are mounted grindi ug tools 21, herein shown as cup wheels of. emery or other suitable grinding material, 1 rranged to rotate as indicated by the arrows. Positiyely driven feed rolls or disks 22 a1 a fast on a shaft 23 driven by gears 24:, 25 from the shaft 26 of the drum 3, said disks i sing so arranged as to'maintain under conste nt tension the paper at the region where it is engaged by the grinders. Each stand 1% is'pivotally mounted at 27 toturn in a h orizontal' plane, be

in clamped in adjustel position by bolts f 28. The pivot 27 is mot nted in a base plate 29 which has a slidin .1 iovement longitudinally of the frame, being adjusted by a hand screw 30. Ears 31 ro;ect upwardly from this base plate 29 an ar 3 provided with oposite end screws 32 to engage an ear 33 pro-- ecting from the stand 13 for-providing ex tremely fine swiveling idjustment for the grinders. Also the base 29 is mounted on a on a bed 35 by means (f a hand screw 36.

suitable receiving mechanism as for instance a reel or winding mechanism 38. Also, as the operation of the machine produces a great deal 'of dust, I preferably provide dustof those gaged by the grinding cup-wheels, as I have found that practically all the diflicnlties which I have experienced by attempts at flat grinding, feeding, etc., are eliminated simply by placing the work under continuous tension at the grinding point, and atthe same time holding the paper at this point in firm contact with a suitable unyielding backing. A further important feature of.

my invention worthy of comment at this point is the provision of means, not necessarily restricted to cup wheels, however, for

giving a straight-out the edgebeing groun rotates in the direction shown and engages the paper only at the lower edge of the wheel, it will be evident that the pull on the paper takes place simultaneously at the opposite edges in a strictly transverse direc- (grinding movement at tion' to the length of the paper, so that, in'

the first place, there is no danger-of rufliing the paper, and in the next place, the engagement is delicate, and finally all twisting tendency or tendenc to distort the paper is done away with. also, I have found that the machine can be run at very high speed so as to give a large output of product. By turning the stands 13 on their pivots 27, the grindlng tools are correspondingly turned so as to grind {the paper to any bevel desired, and this adjust- As'each cup wheel ith this construction,

ment-is further facilitated by the coiiperating lateral and longitudinal adjustments through the hand wheels 30, 36. Also, the adjustments provided by the hand wheels 36, preferably independent, accommodate the grinders to varying widths of paper, and the longitudinal adjustment through the wheels 30 provides for all thicknesses of paper; If itis desired to grind only one edge of the paper, I prefer to handle a double width of paper, grinding its opposite edges the same as in a single width of paper, and then I bring the cutters 37 into actio'n sov as to slit the double width of pa er into two single widths. 'B thismeans' am 'e'nabled to maintain hot the cutters inaction 'posite tools for reduclng opposite lateral the simultaneous or opposing pull which they give away from the edges of the paper and the consequent high speed of operation which this aids in permitting.

"The feeding of the machine is automatic, and in view of the maintenance of an unremitting anduniform tension on the paper at the region where it is being ground, there is no possibility of cutting through any wrinkles or kinks, inasmuch as it is impossible for wrinkles or kinks to form in the paper. This is of special advantage in the case of such papers as straw-board papers, thefiber of which is very weak, and the paper is very liable to break, tear, packer, etc.

As already intimated, I wish it understood that I consider my invention as broadly novel in providin a machine for accomplishing what it as heretofore been considered necessary to accomplish at the paper mill when the paper is being manufactured.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
