To all whom it may concern:

Be it known that l, W'ILLIS H. Howns a citizen of the United States, and a resident of Vtatertown, county of Jefferson, and State of New. York, have invented certain new and useful Improvements in Paper- Making, of which the following'is a specification. Y

-My. invention relates to improvements in paper making and the like and one main object of my invention is to provide an improved process for producing an artistic paper or the like of novel form.

Various other objects features and advantages will more clearly appear from the detailed description given below taken in connection with the accompanying drawings which forma part of this'specification.

In the drawings, Figure l is an outline top plan view-of apparatus which'l use in carryin out my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detailed vertical view of my spraying apparatus. Fig. at is a vertical section taken on the line 1VIV of Fig. 3. Fig. 5 is a plan view of the mottled surface of my improved paper. Fig. 6 is a cross section of the same taken on the line VIVI of Fig. 5.

It will, of course, be understood that Figs. 1', 2, 3 and 4; of the'drawings do not illustrate all the details of construction of the mechanism, since such details are well understood by those skilled in theart and many parts which are unnecessary for an understanding of this invention have been omitted. The views shown in Figs. 5 and 6 are somewhat exaggerated and of course cannot show the exact appearance of the product as it really is.

Referring to Figs. 1 and 2, 1 indicates a Fourdrinier machine which produces a Web 2 sustained upon endless wire 3. A cylinder machine indicated at 5 1s arranged near the machine 1 and is provided with a vat 6 havin therein a cylinder 7. Cylinder 7 delivers its web 9 to the felt 10. The felt 10 extends over suitable supporting rolls'll and the felt being, of course, continuous The wcb-2 of the Four-drinier machine 1 passes between press rolls 13 and then the web 2 Specification of Letters Patent.

leaves the wire 3 and passes between the rolls 12 and is united with the web 9, whence the two are carried along together by the felt 10. The two webs thus joined after passing the supporting roll 8 leave the felt 1O and-pass upwardly about supporting rolls and between the second press rolls 14. The usual felt 15 is provided adjacent the'rolls 14 for removing a certain quantity of moisture from the paper. The two combined webs are then passed over suitable supporting rolls to the third press rolls 16 where the web is subjected to the drying by pres-' sure. After passing the roll 16 the paper web is passed over drying rolls 18 heated by steam and during these operations the two webs become firmly united.

Suitably placed abovethe web 2 is a spraying pipe 19 pivotally mountedupon two links 20 and 21 (see also Figs. 3 and i). The links 20 and 521 are pivotally mounted to some fixed member, as a beam One end of the sprayin pipe 19 is closed while a. rubber tube 23 connects the other end of the spraying pipe 19 with a supply pipe 24., which feeds the spraying pipe 19 with a liquid under pressure. For the purpose of spraying, the pipe 19 is provided with apertures on its underside, through which the spray is emitted. The sprayer shower from the pipe '19 is directed upon the upper outside surface of the web ,2 and in order to cause the same to 'be properly and irregularly distributedthereover the pipe 19 is given a back and forth motion by means of a rotating disk 25 which reciprocates a link 26 pivotallymounted to the pipe 19 at 27. In order to v r. the throw of the pipe 19 the link 26 is pi v tally mounted to the disk 25 at 28, and the pivotal point 28 is arranged to be adjusted at-varlous distances from the axis'of the disk 25 by means of a screw 29. The disk 25 may be driven in any suitable manner, as by a shaft 30 driven from gear 31 of themain machine.

The operation relating to the se arate formation of the two webs by the cy inder and Fourdrinier machines is well understood; and, therefore,.need not be described. i While the web 2 is on the wire of the 'Fourdrinier machine, ityis sprayed or showeicd from the pipe 9 with .Wateror other suitabie drops or streams ofwater the pulp of the web or pcrticics thereof in an irregular manner forming; in most cases irregular and uneven crotch-like Ileprcssionc of VilllUUS alcpthsiii the Web at such stage in the formation of the Web '5 i' the depressions will not refill so that lhc varies in trzinsluccncy and thickness, although the umlcr i of the Web will remain comparatively smooth, That is, the pulp displacing 3.0 displaced by the spraying at such 1;. stage that the displacement for the mom, pawl; rcmuins. This gives the sprnycd surmcc oi. the Web is. wild appearance czuzsccl by thc spraying}; so that a wild sheet is produced,

with its cloudiness appcaring on the face cf the sheet. The we 2 is than united with the web 9 in the well known manner and since the web is formed with uneven alcprcssions and varying ilIlClUlQSS and immluccncy the resulting paper has a, mothlcci (5. The Webs 2 and 3 may hc mrulc of (l 36 Web 2. It may happcii appearance, which Fig. intended to rcpresent.
