METHOD or ANnMEANs non MAKING PAPER.- I

To all whom it may concern:

Be it known that I, DUNCAN INDALE, a citizen of the United States of America, residingat Holyoke, in the county of Hampden and State of Massachusetts,

have invented a new and useful Methodrof and Means for Making Paper, of which the following is a specification.

My invention relates to improvements in methods of decreasing the thickness of a web of paper, during its manufacture from the'pulp and in the paper-making machine,

'whereby such web shall have produced therein one or more sections or channeledleaves be detachable or not, although notrestricted to such use. In order, that the leaves of a book, which leaves consist of fairly thick paper, may be readily turned when the book is opened, shall be fiat when open, and will occupy less space or thickness at the bend,,each of such leaves should be madethinner adjacent to its binding edge, wherefore the aforesaid channeled portions or channels are so arranged in the web as to enable the latter to be 'cut into leaves each of which has a, thin portion extending along a course that is parallel ,with and adjacent to such binding edge. Y

My invention consists in .a method of producing paper, of the character just described, by compressing with ,mechanical means portions of the web 'while in a pulpy state on the Fourdrinier or cylinder and at' interior buckets, a receptacle, trough orv funnel over which such buckets are carried] and into which they empty, and a conduit or conduits leading from said receptacle or funnel, for carrying said method into effect,

all as hereinafter set forth.

More broadly considered or expressed,

perhaps, the method may be said to'consist" in simultaneously compressing in part and Specification of Letters Patent.

of and in the r removing in part a portion of thethickness L. MoConK- of the web along and between lines extendmg longitudinally of said web.

As a preliminary step to the foregoing method and a step therefore in an amplification of my method, some of the pulpy material is dispersed prior to compressing and removing what remains. In other words, a shallow straight ,path or track is made inthe web,such track being made by subjecting the moving web to a fixed member which dips down into and disperses a portion of the same, so as to present a thinner portion of the" webto the compressing and removing agency. And the means for thus dispersing the pulp and forming the initial track also enters into the mechanical part of my invention.

the pulp is thick and possesses certain char: acteristics, that a sufiicient amount will not be removed at the time the compression takes place, in consequence of which the thickness to-be'compressed is too great, and in that eventthe fibers are crushed by the compression and'the channeled portion has a mottled appearance and its texture is im- 1 paired. a

The primary object of myinvention is to provide a practical method of; and comparatively simple yet highly efiicient mechanism or means for producing paper which can be cut into sheets that have marginal and body portionsconnected by-thin portions,

A further object is to provide such a method that can be carried out with theaid of or in connection with an ordinary papermaking machine of either type, and such means that areadaptable and applicable to and capable of being readily and practically incorporated with such a machine.

Other objects and advantages will appear in the course of the following description.

The invention is illustrated with the aid accompanying drawings, in which' A Figure 1 is a front elevation of mechanism'which embodies a practical form of the mechanical part of my invention as applied toa Fourdrinier machine, one of the adjusting sleeves being in section, portions Without this pre-' vhmmilry p there may be danger, when PatentedJuly 2c, 1915.

Similar numerals refer to similar parts throughout the several views.

Before referring specifically to the drawin 's, it may be stated that in detail the method, for the putting into effect of which the mechanism illustrated in said drawings is provided, consists in moving a web of paper material, while in a plastic condition on the wire of an ordinary Fourdrinier ma chine, or on the cylinder of an ordinary cylinder machine, first under one or more dispersing members set to produce a corresponding number of shallow paths or tracks in such material, and then under the same number of rotatably mounted members so arranged as to displace or compress such material, along the paths or tracks already formed therein, and so constructed as at the same time to remove by contact and convey away portions of such material from the same paths or tracks,whereby the portions of said web thus acted on by said members are left thinner than the body part outside of the lines of action of said members, and thinner than the initial track portions. The web, after being channeled in the manner and by the method just explained, passes over a suction-box, usually the first suctionboX, and thence onward to completion the same as though my new method had not been added to the paper-making process. Additional details of the method will be eX- plained in connection with the following description of the mechanism.

The mechanism for carrying out the new process or method comprises a movable hollow drum or wheel 1 having a multiplicity of slots, holes or openings 2 in the periphery or rim, and provided on the inside of such rim with a plurality of buckets 3, and on the outside of such rim with a wire covering 1-, and a funnel 5 arranged within said wheel beneath the circular path described by said buckets as the wheel revolves, together with supporting and adjusting means for said wheel and conduits leading from said funnel, which will subsequently be described in detail. A tracker or spreader 6 is also included in the aforesaid mechanism, and this also will be described subsequently in detail The wheel 1 is mounted in such a inanner, relative to the pulp-carrying member of the paper-making machine with which the channeling mechanism is incorporated, that the pulp as it is carried under said wheel is crowded together or made thinner than the pulp-that passes on both sides ot the wheel periphery at successive points of con tact with said pulp, said wheel being rotated by reason of its contact with the moving pulp. This thinning process could not be successfully carried out and the desired result produced, however, without making provision for the removal of a portion of the pulp along the course of the channel, and to this end the openings or perforations 2 and the buckets 3 are provided, the particles adhering to and taken up by the wire surface l of the wheel and a portion of the displaced fibrous material escaping between the wires of said surface or covering and through said perforations and being re ceived in said buckets which deliver them to the funnel 5. The surface of the wheel 1 which contacts with the pulp must necessarily be of wire, either woven or spirally wound, for reasons which are well understood by those skilled in the paper-making art, and such surface naturally picks up some of the fibrous or pulpy material, and

this together with any of such material that is in excess of the amount that can successfully be packed together in the formation of the bottom of the channel or might possibly be displaced laterally is removed from the paper-making field in the manner and by the means just explained, at the same time that the packing or compressing operation takes place. The same means also prevents, of course, the accumulation of pulp on the wire periphery of the wheel, which accumulation would be fatal to the successful operation of the mechanisn'i.

The covering 4 which I have shown consists of wire spirally wound on the wheel rim, but such covering may be of a similar nature to the covering or outer surface of a dandy-roll.

The buckets 3 are arranged so that the entrance thereto or the openings into their pockets are behind in the direction of retation of the wheel 1, like buckets in any ordinary rotary conveyor.

The wheel 1 has a hub 7, and this is loosely mounted on a sleeve 8, which in turn is fixedly mounted on a tubular support or hollow rod 9 having a longitudinal slot 10 in the top thereof. The hub 17 is held against endwise movement on the sleeve 8 between and by means of an external shoul der 11 on said sleeve and a collar 12, said collar being mounted on said sleeve and secured thereto by a thumb-screw 13 that is tapped into said hub and with its inner end engages said sleeve. The sleeve 8 is held against end'wise movement on the rod 9 by means of thumb-screw 1 1. The thumbscrew 14 is tapped into the sleeve 8 and engages with its inner end the rod 9.. Upon loosening the thumb-screw 14, the sleeve 8 with the wheel 1 can be moved to any re quired point on the rod 9, when said thumbscrew is retightened. Thus the wheel 1 is adjusted so as to locate the channel to be formed thereby in the web the required distance from the adjacent edge of such web or from the adjacent channel to be formed by another wheel. The hollow stem 15 of the funnel 5 is tapped into and through the top of the sleeve 8, and projects downward into and through the slot 10 in the rod9, which slot is provided to enable the parts to be adjusted longitudinally of said support.

The waste material is delivered to the funnel 5 by the buckets 3 as they pass over said funnel, such material dropping out of the same into said funnel, and passes down through the stem 15 into the passage 16 in the rod 9, from whence it is conveyed away, usually escaping from one or both ends of said passage.

Besides making provision for the lateral adjustment of the wheel 1, it is necessary to provide for adjusting said wheel to and from the pulp-carrying member, in order to produce a channel of the required depth. For this purpose I employ saddle bearings l717, in which to mount the rod 9, and provide these bearings with externally screw-threaded depending stems 18-18 which are received in internally screwthreaded sleeves 1919 having top flanges 2020. Sections of the frame of a Fourdrinier frame are represented at 21-21, and the sleeves 19 are arranged in vertical openings in such frame sections with their flanges 20 resting on the upper surfaces of said sections. Thus the bearings 19 are supported by and above the frame of the machine. The flanges 20 have radial openings 22 therein to receive a rod with which to turn or rotate said flanges and the sleeves 19. By rotating the sleeves 19 in one direction or the other the stems 18 and the bearings 17, with the rod 9 and the parts.

mounted on and supported by said rod, including the wheel 1, are lowered or raised accordingly, and said wheel is positioned nearer to or farther from the pulp-carrying member, which in the present case is a Fourdrinier wire. A section of the aforesaid wire is represented in Fig. 5, and a fragment in each of Figs. 1 and 4:, at 23.

A pair of pins 2t may be provided with which to secure the rod 9 immovably to the bearings 17, such pins passing through transverse openings in said rod and bearings, as best shown in Fig. 5. When it is desired to support the channeling mechanism well above the wire 23 and entirely clear of thepulp if any on said wire, for i the purpose of lateral adjustment of the parts, or for any other reason, the pins 24: are withdrawn, the rod 9 is raised-high enough to enable said pins to be reinserted in the bearings 17, which is done, and said rod is then permitted to rest on said pinssee Fig. 6. The rod 9 is relocated in the crotches of the bearings 17, after the required lateral adjustment has been made, or when all is in readiness for operation.

In Figs. 1, 4; and 5 a portion of a web of pulpy paper material is represented at 24:. The channel being formed by the wheel 1 in Figs. 1 and 4: is shown at 25, while in Fig. 5 three such channels are represented, there being actually that number of wheels 1 in the Fig. 5 arrangement, although the middle wheel and parts are omitted in order to show more clearly the channel, and the preliminary or initial track to which ,reference has already been made and which will be presently explained in full detail. The

number of combined displacing or compressing and conveying wheels, that may be employed in connection with a web,.depends' upon the number and location of channels which it is desired to form therein.-

The channel which this mechanism produces has sides that stand approximately at right-angles to the bottom, in contradistinction to sides that are more or less inclined outwardly, so that said channel is quite sharply defined and of a pronounced character, thereby rendering the paper in which the channel is formed most efiicient for'the purposes for which such paper is intended.

The tracker (3, which is provided when necessary to relieve the wheel 1 ofsome of itsjivorln-consists' of a plate that is prefer ably dished at the bottom so-as to present to.

the pulp 24, in the direction of movement of the latter, a slightly curved surface laterally and a well rounded surface in the other direction, means being afforded for suspending such'plate behind said wheel and at an incline downward and forward in the aforesaid direction of movement. Theplate of tracker 6, so constructed and when properly adjusted, formsashallow track 26 in the moving pulp 241-, behind and in line with the wheel 1 and just before the latter is reached, such track being concave in crosssection, or deeper in the center, than at the edges. 6 displaces, spreads or disperses the pulp laterally, as said pulp moves along on and with the wire 23, without cutting,gouging, or digging harshly or too abruptly into the soft or plastic mass, to do which wouldbe disastrous. The tracker 6 is somewhat wider than the wheel 1, consequently the track 26 is wider than thechannel 25. If the track 26 were only as wide as the wheel 1 or narrower that said Wheel, the pulp In making the track 26 the tracker would be improperly acted on and unevenly or disproportionately channeled upon reach ing the wheel.

In the present case the tracker 6 is secured, by means of a long bolt or headed rod 27 and a thumb-nut 28, to an arm 29, and the latter is mounted with the wheel on the sleeve 8. Being mounted on the sleeve 8, the arm 29 and the tracker 6 are adjusted laterally and to and from the wire 23, with the wheel 1, which is a decided advantage, as will be readily seen. The rod 27 passes through a sleeve 30, at the top of the tracker 6, and one end of the arm 29, and the thumbnut 28 is placed on the part of said rod that protrudes from said arm. Upon tightening the thumb-nut 28 against the arm 29, the head of the rod 27 is forced against the sleeve 30 and the latter against said arm, so that the tracker 6 is held securely in place relative to said arm. The thumb-nut 28 affords an independent adjustment for the tracker, since said tracker, when said thumbnut is loosened, can be rocked on the rod 27 to locate the base of said tracker nearer to or farther from the wire 23. The end of the arm 29 that is opposite to the bolt 27 is in the form of a split collar 31 which fits on to the sleeve 8, a thumb-nut 32 being provided for the free ends of said collar, with which to bind said collar to said sleeve. Upon loosening the thumb-nut 32 the collar 31 can be adjusted on the sleeve 8 ciroumferentially, whereby another independent adjustment for the tracker is provided. The tracker is adjusted or set as a rule so that its maximum penetration of the pulp is less than that of the wheel 1.

In practice, the pulp or web 24 travels on and with the Fourdrinier wire 23, in the direction of the associated arrows in Figs. 4 and 5. As the web 24: passes under the trackers 6 the portions of such web that contact with said trackers are dispersed thereby and the shallow concave paths or tracks 26 are produced. Then, as the web continues on its course and the tracks 26 reach and pass under the wheels 1, these prepared portions of said web are formed or converted into the channels 25, by the action of said wheels in displacing or compressing the pulpy material between themselves and the wire 23, and in removing the surplus uncompressed particles. The wheels 1 are rotated by the moving web in the direction opposite to that of said web, and in rotating receive and dispose of the surplus pulpy material, discharging the same into the passage 16, with the aid of the buckets 3 and by way of the funnel 5. The channeled portions of the web, in being compressed between the Fourdrinier wire and the wheel, undergo little if any lateral displacement, owing to the fact that what I have termed the surplus materialis conveyed away. It is not meant by this, however, that the stock or material is scraped or scooped out as it were until only the thin bottom of the channel is left, which bottom in that event would be too fragile and weak to hold together, because such is 1 not the case. Enough extra material is pressed into the channel bottom and enter into its formation to render the same strong and serviceable, the channel-forming wheel taking away only enough material to avoid clogging the covering 4, on the one hand, and to prevent piling up the material at the sides of the channel and so producing paper with an uneven surface outside of the channel, on the other hand. When the wheel is properly adjusted relative to the Fourdrinier wire and the pulp thereon, said wheel automatically takes away the required proportion of such pulp, or, it may be said, antomatically determines the amount of surplus stock or material to be removed and removes it.

When this mechanism is employed on a Fourdrinier machine, the member or members which both compress, condense or dis place and remove portions of the web, and which may be termed combined squeeze and conveyor members or wheels, or combined compressors and conveyors, are located behind the first suction-box in the direction of travel of the pulp-carrying wire.

I am aware that different methods of and means for producing channels in paper have been heretofore employed, such, for example, as by grinding or skiving the finished paper with suitable mechanism, or by employing a rotary member to displace and compress the pulpy material brought into contact therewith, without removing an y of such material, however, and extracting by suction moisture from the thin portion, or by treating the web with air pressure, either suction or blast, whereby some of the material is removed entirely or merely displaced by being blown over adjacent portions of the web, and I lay claim to none of these meth ods or the means for giving them effect.

Necessarily more or less change is re quired in order to adapt my mechanism to different paper-making machines and for operating on different kinds or grades of plastic material, not only in the shape and size of some or all of the parts, but also in the arrangement and construction thereof, and I do not desire or intend to be restricted to the particular means herein shown and described for obtaining the needed adjustmerits.
