CHARLES E. POPE, OF THC LYOKE, MASSACHUSETTS;

AU'TCSHATIC PAPEB-MACHDJE.

Application filer April 1915. Bcrial 210. 39,038.

To all whom it may concern t 1 r Be 1!; Known that L Qimnmcs b. l urn, a.

I citizen of the United States of America, re-

siding in the city of i'iolyoke, county of Hampden, and State of Massachusetts; have invented certain new and useful Improvements in Automatic.Paper-Machines, "of which the following is a specification. i

' This invention relates to a fast running paper machine and particularly to improved 3 means and arrangements of parts whereby the web is transferred automatically from the squeeze or ress .rolls to the driers.

The object 0 the invention is to provide an improved arrangement of parts by which the paper making machine may automatically transfer theforward endof a fast running web from the last squeeze rolls to the first drier characterized in the provision of positively acting means to force the web '-'to follow the bottom felt from the last squeeze r lls to a point adjacent the first drier, a guiding means between the first drier and the point where the forward travel of the bottom felt ends to which the running web may jump from tlie feltand mean'sto automatically force the forward end of the. web fromthe guiding means'to and. be

tween the first drier audits felt.

Other objects will appear in the detailed description and annexe-d claims.

. A preferred embodiment of my invention is shown in theaccompanying drawings for illustrative purposes and will now be described In the drawings: Figure l is a diagram matic view of the arrangementof the parts of my invention; Fig. 2 is a side elevation of a paper making machine, showing only the arts thereof pertinent to an underfian of the invention by those skilled Y in the art; Fig. 3 is a diagrammatic detail "view of a modification of one feature of the invention; Fig. l is a detail plan View of one feature of the invention associated with the last squeeze rolls; Fig. 5 is a detail sectional view taken on ..the line 55 of F 4. V ghe features of the invention bywhicli on the start of the machine the web is automatically transferred from the lowerfelt to the driers will first be described. As well known by those skilled in the art the web, at the start or after any break in the process of making the paper,'must be car- 'ried through the machine and fed to the Specification of Letters Patent.

driers either by hand or automatically.

Rather than handle the entire .width of the web it is customary to form on the wire a ribbon which is carried through the machine and afterward leads the web of full width for the normal operation.

Referring to F igsl 1 2, 4, and 5, the last 7 squeeze rolls 1 and-2 receive therebetween zthe lower felts; with theweb Y (at. first-a -ribbon) thereon. -The' top roll 2' is bare so that there is a tendency for the web to stick I:

to this roll. Howevenbefore the ribbon has followed the roll 2 any substantialdistance it meets arevolving brush13iarran'ged' to, rotate oppositely 'to roll 2 at one side "(the side along which the ribbon: is customarily j; i fed); This brush 3 preferably of wire bris ties strips the .ribbon from" the roll and thro vs it down on thefelt .fl. The latter is guided horizontally beyond the squeezerolls to guide roll 5 adjacent the periphery Qftlle first drier l1 where it returns over otherrolls 5. In line with the upper roll5 and Y between'it and the first drier ll-is a guide '80 roll 30 supplied with a'doctor 31; Above and a little beyond the ro lll30 is a horizontally arranged pipe 32 connected to a source of air under pressure. downwardly directed outlet as indicated in Flg.'1. v V

' Now if it is assumed that the machine is a fast running one the ribbon 6 is loosened from the roll 2 by brush '3 and the loosened vend is carried by the felt 4 horizontally so that it jumps the distance between adjacent This. pipe has arolls 5 and 30 and into line with "the downwardlydirected blast from pipe 32. The

latter forces or blows it downwardly be tween the bight of drier cylinder 11 and its' felt 9 whereupon the ribbon is pulled down and around roll 30. 'If for any reason it should start to 'wind on roll 30 the doctor 31 will strip it other. a' point above its proper entrance on drier 11. .Thus the paper is automatically and efiicientlytransferred from the squeeze rolls to the first drier by improved means.-

The manner-of mounting and rotating the brush 3 is shown in Figs. fl: and 5. An

arm 15 pivoted to the side frame Am 17 has i a horizontal bearing in which is mounted the shaft of brush 3. On the outer end of the brush is a pulley driven by any suitable driving means as 18 and 22. The brush may be positioned by swinging arm 15 and clamping it as desired to frame A.

' A modification isshown'in Fig.- 3 in which the web 6 jumps from felt 4 to the bight of suitably driven pressure rolls 19 and 21.

The latter is made of rubber or an equi\'a-- have an improved appearance or finish.

A brush 8 bears against roll QO and oper ates in conjunctionwith this roll in all respects like the brush'3 already described and of which it may be a counterpart. If the web starts to wind on roll brush 8 will throw it down to enter'the bight of drier 11 and its felt 9. Adoctor'on roll 19 is positioned to prevent the web from winding on this roll. In any case the web is directed downwardly for proper application to the first drier.

The improved arrangement of the drying cylinders will now be described. As indicated in Figs. 1 and 2 each lower cylinder 11 of a series is located with its a.\'is vertically below its companion cylinder of the upper series. The upper and lower cylinders are arranged only a small distance apart or in such a way that the forward end of the web or ribbon as it runs rapidly through the machine may jump from the lower cylinder to the bight of the upper one and its felt without climbing an appreciable distance and thus be transferred by its momentum. To this end a doctor 40, Fig. 1, is arranged to strip the ribbon from cylinder 11 as it reaches its upper horizontal'travel. The lower guide roll 41 f0" felt 14 directs the latter to cylinder 12 from a point just back of tliedoctor 40 so that as the ribbon 6 leaves drier 11 it will jump to the felt 14 traveling rapidly to drier,12 and be directed' and carried to the latter dricr, and

this result is automatically obtained without the interposition of any structure not herc tofore found in driers, but by an improved arrangement of the old structure. or ribbon G is stripped from drier 12 by a doctor as it is traveling thereon vertically and downwardly. The upper left hand guide rollers and lower right hand guide rolls 41 for the lower and

upper felts

9 and 14, respectively, are mounted close to their respective dryin cylinders 11 and 12 as shown. The we 6, therefore, in passing from the upper driers to the lower driers travels automatically and freely exposed on both sides a vertical distance from one drier to another about equal to that between the axes of the upper and lower driers. The free space on both sides of the exposed web rmits the vapor, which would otherwise b: imprisoned to a large drgrce with the The web.

-table brush mounted to bear web, to escape and thus advance the drying operation.

In addition to the automatic transferring feature of the invention from one drier to the succeeding one and the other advantages 1 of the arrangement described it is clear that a considerable amount of floor space is saved by mounting each pair of driers substantially one above the other as described,

\Vhere the driersare arranged as hereto- 7'5 fore in staggered or zig zag relation the dis tanee of at least the diameter of one cylinder 15 necessary for a given number of driers,

in excess of the space required for the improved arrangement described. This improved arrangement of drying cylinders is not claimed as a part of this invention but forms the subject-matter of my copending application, Serial No. 82,409, filed Mar. 6 1916. i i

It is not thought necessary to use any space indescribing the driving connections for the several parts or specific manner of mounting them in the machine. From the drawings. and description disclosed one skilled in the art can readily put the inven-' tion into use. The invention is defined in its proper scope by the appended claims rather than by the foregoing specific description; '95 I What I claim is v V 1.
