As shown in the drawing, thatpart of the machine which is associated with the pulp feed box, from which the pulp is fed to the breast roll, is designated generally by the numeral 15, this part of the apparatus being fixed, and having the breast roll endof the shakng or forming section associatedtherewith, the other end of'this;sectionbeingas sociated with a fixed part of the frame which is designated generallyby the numeral 16, this apart also -:being "stationary. For purposes of convenience in description, this shaking part of the Fourdrinier is hereinre ferred toiasthe forming section, because the -;a-ctual forming ,ofthe sheet of paper is largely completed while the wire passes through the extent -of this shaking part. The forming section comprises va truss at each-side, the upper rail iof which serves 'assayshakingside rail. l b-t the couch rollend the formingsectionds provided :at each side, -withra heel pivot which in this case consists aof :a :readily :rcmovable pin :22, extending throughaa.suitable holeiin the shaking side rail into a socket in the fixed partofthe frame; the forming section during operation roscillating in a substantially horizontal rtp'lanerabout theheelpivots. .Thetruss member may be of any desired COIlSt1llCtl0n,1bITlt ipreferably each truss member consists of the two end fHlGlDbGlfSLQS'flHClQl, which are connectedeat their'lower ends by means of beams 25, suitable struts 26 being positioned betwecngthe side rails20 andathe beams to strengthen and add rigidityto the trussconstruction. .Mountcd upon .thennachine are the usual deekle straps 27 which travel "through wash troughs 2'8, and around the -pulley29,'these parts being of convertional construction.

Associated with each side of the forming section, at the breast roll-end, is .a support- ,ing'and shakingmen'iber which is designated :generally by the numeral 35,:each of these fshakingsupports receiving at its upperend, shown most clearly in "Fig.7 3, a housing 36, 'wl1icl1,;as shownclea-rly in Fig.2, is in the mature ofqa'jaw member, adapted to receive i-the bearin f retaining sleeve 37. Within this :bearing sleeve .is mounted :a ball bearing which receives theend'of the shaftofthe breast roll. A capt38 is remov-ablylheld'in 1111389 "within the ,j aw member 36by means of bolts l 39, this cap I serving to retain the bear- ..ing'sleevein position within the housing 36,

to thus hold :thebreast roll in operating po- :sition. In eachbearing a'suitable. end thrust receiving member 40 is provided. These anembers notzonly take up'end thrust, but :by adjustment wearzmay beitaken up so that the undesirable shaking 1 due to lend play of the breast roll will be avoided. By removing the bolts 39 the cap 38 may be withdrawn and the breast roll with its bearings removed as a unit, the relative adjustment of the roll shaft in the bearings being thus undisturbed. These bearings are preferably provided with end shields 41 which prevent the flow of waterthereinto.

It is notessentialethatball bearings be used, but suitable roller bearings or even conventional solid bearings may be used if desired. .Roller bearings of course, should be retained within a bearing sleeve as described above socthat the breast, roll and'the two bearings may fbemove'dias a unit and without disturbingthe adjustment. of these parts. vThis jaw .member 36 is adapted to receive, in pvotal connectionythe breast roll end of each of the shaking side rails 20,each of these railsibeing connected to one ofthe jawmembers'flby..means-of. a pin 42, which extends through an opening in theirail 'and is threadedly mounted within apivoted member tficarried within a. suitable-socketin the .jaw; member. One of theseshaking supports as-showniin'lfig. o,'is providedwith a socket member 4A, which is adapted to receive one end o fea shakelbar 45,.the other endof this :horizontal shakingof the breast roll-end of the "forming section.

As shown most clearly 1n Fig. each of these shaking supports comprises a chair .neledframe memberi50, which adapted to receive the lift bar 51. are of similar construction except that only These -two supports onehas a socketfor receivingthe shake bar 4-5 and therefore onlyone need be described in detail. "The *framemember is provided at its vlower end with outwardly extending trunnion members 52, each of which is adapted to west upon the upper face of a base member 53, which is in turn rigidly fixed to the foundation in any suitable maneThisLbase member is provided with an opening'54: through which extends the'lower endof the frame 50, and the lower end of the [lift bar 51. Each ofthe two base lnem .bers has-an upward extension to which are connected the opposite ends of a beam '56, which holds the parts in fixed relationship. Each .of the'base members is also provided at each side of the opening 54: with upwardly extending, and-overturned, flanges 57, which cooperate with the trunnion extensions 52, and retain those extensions in defi nite position. During operation lubricant is placed within the pocket formed by the flanges 57 and a plate 58 is positioned within the opening 54, at each side thereof, to prevent the escape of the lubricant. Also a plate 59 is positioned at each end of flanges 57 to prevent escape of lubricant. The lower face of each of the trunnion extensions 52 is curved. Each lift bar 51, at its upper end, is provided with lateral extensions 60, the upper faces of the lift bars and of these lateral extensions being curved, the curvature thereof corresponding to, and being of the same radius as the curvature of the lower faces of the trun nion extensions 52. In other words, as indicated by the dotted line A in Fig. 7, the hearing faces of the trunnion extensions 52 and of the upper end of the lift bar 51 and its lateral extensions, are curved planes lying within the surface of a given cylinder. Each of the trunnion extensions 52 is pro vided upon each side face with a facing member 61, which is rigidly'secured thereto, and the outer face of which is curved. Positioned within the retaining flanges 57, and cooperating with each of the facing members 61, is a complementary gib or strip 62, the cooperating faces of these strips 62 being curved to correspond to the curvature of the outer faces of the members 61. If desired suitable strips, in the nature of shims, may be used to back up the strips 62. As shown one of these strips 63 is of steel and the other 64 of leather. This is pre ferred for the'leather serves to absorb some of the shock arising during rocking; but any suitable material may be used for these shims. The construction is such that when thus assembled the flanges 57 overlie the facing members 61 and gibs 62 to retain the frame 50 in position with respect to the base 53 and sincethis base member is fixed, any rocking of the lift bar and frame through the medium of the bar 45 will necessarily cause those parts to rock about the trunnion extensions 52,. which are restrained against bodily movement, by the parts just described. The upper end of the lift bar, and its lateral extensions 60, has mounted thereon a cap 65, which supports and has connected thereto against sliding motion, the jaw member This cap member is preferably integral with the jaw member 36. This cap is provided with downwardly extending and overturned flanges 66, within which are positioned strips 67, similar in form and function to the strips 62 heretofore described, which are also backed up by suitable shims 68. The upper end of each lift bar and its extensions are provided with facing strips 69, which are similar in form and function to the strips 61 described above. will cause the casing 50, with the parts con- As the bar 4-5 is moved itnected thereto, to rock about the trunnion extensions 52. And since the upper ends of the lift bars 51 are connected to the side shake rails, through the medium of the jaw member 36 and the pins 42, an oscillating motion will be imparted to the breast roll end of the forming section, as is the usual practice. But inasmuch as the lower face of the trunnion extensions 52 and the upper face of the lift bar 51 and its lateral extensions (50, have the same curvature a substan tially frictionless motion will result since the trunnion extensions will roll upon the cooperating faces of the bases 53 and the upper curved faces of the lift bars and the lateral extensions thereof will roll upon the cooperating face of the cap 65. Consequently a true rolling motion results, which is practically free from friction. Furthermore as a result of this construction the cap 65 will move in a substantially horizontal plane, with no up and down motion, as is inevitable with the usual type of support which pivoted at its lower end to some fixed part of the foundation, and is also pivoted at its upper end to the shaking frame. The curvatiu'e of the cooperating faces of the members 61 and 62 and members 67 and (S9 is such that as the casing 50, and the lift bar therein, are subjected to this above described rolling motion these cooperating faces will slide freely one upon the other, this construction being analogous to that present in a well constructed ball and socket joint. The members 6162, 6769 tak up any end thrust that is present during operation of the device, and also provide means whereby wear may be compensated for. lhreadedly mounted within the flanges 57 are the adjusting screws 63', through manipulation of which the shims 63 may be moved to compensate for wear. Each of the caps- G5 is also provided with similar adjust ing screws 68'. Plates 59 and 69' are provided for preventing the escape of lubricant from about the upper end of the lift bars.

One of the great defects present in shaking sections as heretofore used has been the difficulty of securing adequate lubrication of the surfaces of the shaking supports. Consequently wear has been comparatively rapid, although the movements of these parts are slow. And in fact it has been this slow .movement which gave rise to the ditliculty of obtaining adequate lubrication. But with the construction shown herein the surfaces which sustain the weight of the parts have a rolling motion relative to each other and wear therefore practically negligible. However these parts are surrounded by lubricant during operation as the cooperative faces of the members 61(52, 67-69 have sliding motion relative to each other and hilu'ication is needed. As is obvious from the drawing the construction of these-supmounted-upon the shaft 85.

porting members is such that they pump oil 'in'betwcen the faces of thesecooperating parts'during rocking of the supports and adequate lubrication is thus secured even though the partsmove so slowly.

*Each of the lift bars 51 is provided in one face with rack-teeth 70. The channeled frame is provided with a cover 71. Mounted in'this cover is a shaft '72., which is provided within its length with an enlargement having teeth thereon, thus constituting a pinion '73, the teeth of which mesh'withthe teeth uponthe cooperating lift bar. Also mounted within each cover 71Jis a second shaft 7 lwhich is arranged parallel to the shaft 72. Connected to the cover 71 is a gear case 75, provided with suitable openings to receive the respective ends'ofthe shaft-s 72 and 7 1, the end of each shaft-extending through these openings into the gear case. Suitably connected to the gear case is a gear case cover 76. Mounted upon the 'outere'nd of the shaft '72 is a gear 77, which meshes with a corresponding gear 78,which isinounted upon the shaft 7% intermediate its length. Also mounted upon the shaft '74 is a worm gear 70, which meshes with a worm pinion mounted upon the shaft '81, the outer end of which has a sprocket wheel 82 pinned thereto. This sprocket wheel receives a chain 83 which also runs over a second sprocket wheel 8 f, This shaft is supported at its opposite ends, in suitable beaiingswl1icl1 are mounted in the standards 86, and carries thereon two of the smallesprocket wheels 8%, one adjacent each end, which wheels cooperate respectively with the'two sprocket wheels 82, there being one of'these sprocket wheels 82 associated with each shaking support. At one endthe shaft is provided with a hand wheel 87, which is so positioned that it may be readily man ipulated byanoperator. pon movement of the hand wheel to cause rotation of the shaft 85, the gear members associated with the two lift bars will be actuated to cause up and down movement ofthose lift bars to raise or lower the breast roll end of the forming section as desired. And by properly proportioning the gears, sprocket wheels, etc,

the two lift bars may be caused to move in unison, to raise, or lower each side of the shaking part the same amount.

This'type of shaking part as is the general practice, is provided with the usual table rolls 90, and with save-alls. It is quite desirable, and is the usual practice, that the save .alls which are associated with shaking parts shall be maintained stationary during operation. This is ordinarily accomplished by mounting the save-alls upon supports which are entirely separate from the frame of the shaking part, being secured to the foundation of the machine. As shown in the drawing the save-alls, in this invention, are supported by the frame of the shaking part itself.

Two savealls are shown, a first save-all 100 and a second save-all 101; but of course any desired number of save-alls-may be used. The first save-all is supported at one side by the upper edge of the secondsave-all, which in turn is supported by the frame of the shaking part. The other, or front, side of the first save-all has an I-beam 102 rigidly attached thereto, to which is connected at each end a bracket 103, having a roller 10 i:

therein. Carried by each of the front members 24: is a forwardly extending bracket 105, each of which has a stub shaft 106 mounted therein, and positioned to receive the rollers 10 1 to support thefront side of the first saveall. The second save-all. is provided, upon each side thereofwith an angle iron 107, which is of more rigid material than the body of the save-all and serves as a track to ride upon the flanged rollers 108, each of which mounted upon a bracket 109, which is in turn rigidly secured to the frame of the shakingpart. Each of the save-alls is thus supported by the frame of the shaking part, but is movable relative thereto, within a given range. In order to maintain each of the save-ails stationary while the forming part is being shaken during operation, each of these save-alls is connected to a stationary standard, which holds the save-all against movement sothat the frame of the shaking part will move back and forth under the save-ails which ride upon the rollers, free movement of the savc-alls and frame of the shaking part relative toeach other being thus permitted. Th'e'st'anda'rd 110, which is associated withthe first save all and the standard 111 which. is associated with the second saveall are substantially identical in construction. The construction of these standa-ids is clearly shown in Figs. 1 through l. Each of these standards has a slot or groove 112 therein, through which a retaining bar 113 extends, the inner end of this bar being cut away as shown at 114; for positioning within a grooved bracket carried by the respective save-ails. The grooved bracket associated with the first saveall 1.00 is clearly shown in Fig. i and gnated bythe numeral 115, this bracket being preferably carried by the bracket in which the roller mounted. The bracket which is associated with the second save-all 101 is clearly shown in Fig. 1, for example, and is designated by the numeral 116, this bracket being preferably mounted directly upon the save-all itself, or upon the track 107. Secured upon each of the retaining bars is a collar 117 which ispositioned for contacting with the inner face of the standard, when the bar is in assembled position. The outer end of the retaining bar is threaded to receive a hand wheel 118, which end of the spring contacting with a slidable collar 120 which is pressed. by the spring against'the standard to clamp the standard between the two collars. By proper manipulation of the hand wheel the tension of the spring may be varied so that the retaining bar may be moved to, and held in, any desired vertical positioning within the slot in the standard. Due to this construction the save-alls are held relatively stationary as the forming. section is given its shaking motion, the shaking part running back and forth under the save-alls which are restrained against movement by means of the bar. lVhen desired the retaining bars may be manipulated to remove the cut away ends from the grooves in the brackets so that the save-alls may be then moved with the forming section.

This first save-all is closely associated with the breast roll, and the breast roll doctor is preferably mounted therein. This doctor consists of a metal plate 125 which is faced with a wearing plate 126. At each end this plate 125 is rounded to ride in a corresponding groove in a bearing member 127, which is riveted to the save-all. Also at eacn end the plate 125 has an upstanding extension to which is bolted a lever 128 which extends beyond the front end of the save-all and has a weight 129 hung thereon. By means of this construction the breast roll doctor is at all times urged by the weight to swing upon the bearings 127 to hold the plate 126 snugly against the surface of the breast roll. Proper positioning of the breast roll doctor relative to the breast roll is thus at all times secured. And because of the pivotal mounting which is used, the breast roll doctor may be readily lifted, bodily out of the saveall when this becomes desirable.

Carried by the frame of the shaking section, at each side thereof and adjacent the.

opposite ends of the first save-all, are two tracks 131. Connected to each end of the first save-all is a hanger 132 which has a roller 1323 mounted thereon which rollers are mounted for cooperation with these tracks. Because of its considerable length the first save-all is cumbersome and unwieldy and this track and roller mounting facilitates handling thereof. For the tracks 131 sustain the weight of this save-all through the 'medium of the hangers and rollers so that it may be readily handled in moving it f: m operative position back into the second save-all which is the inoperative position.

As stated above, it is necessary to change the wire in a machine of this character every few weeks, and this constitutes a laborious and difficult task; but in the device shown herein this task is very greatly simplified, for means is provided whereby the forming section, with a number of its associated parts, is moved bodily out of the way so that the changing of the wire may be readily accomplished.

During operation the side shake rails are pivotally connected to and supported at the couch roll end by the frame 16; and are pivotally connected and supported at the breast roll end by the shaking support 35, through the medium of the aw member 36.

Positioned at each side of the Fourdrinier part and adjacent the ends of the beams 25- are track supporting standards 150, each of which has two inverted V-shaped upright extensions 151 (which are adapted to receive a V-shaped track member 152. Pivotally mounted upon the beams 25 at each end thereof are roller bearing frames 153. As

shown there are two frames at each end of each beam, one on the inside and one on the outside of the beam, each of them being provided with an extension 154, which is pivotally positioned within a passage 155 in the enlargement 156 of the beam the extensions 154: being in alignment when positioned within this passage 155. These two frames are held within the passage 155 by means of a bolt 157, which holds them against separation, and therefore holds them in place. Each of these frames is provided with two rollers 158, one at each end thereof, which are adapted to cooperate with the tracks 152, as shown in Fig. 2. The tracks 152 are used only when the forming section is being moved into, or out of, alignment with the remainder of the machine, and they are not in position when the machine is completely assembled ready for operation, as shown in Fig. 1. When it is desired to move the forming section out of alignment with the remainder of the machine it is first lifted up wardly. The breast roll end is lifted by proper -manipulation of the lift bar, the couch roll end being raised by means of a screw jack 160, which is supported by a suit able bracket attached to the frame 16. lVhen the forming sect-ion has been raised sufliciently, to substantially the osition in Fig. 2 for example, the breast r0 l doctor is lifted from its bearings and laid down in the pan of the save-all, the first save-all is then lifted and slid back into the second, deep, save-all 101, as shown in Fig. 2. The caps 38 are then removed from the breast roll, with its bearings, picked up bodily by means of a crane or in some other suitable manner, and hung on the brackets 105. This of course causes slacking of the wire, a supporting bar, which is not shown in the drawing, being temporarily positioned in place to hold the wire while the forming section is being moved out of, and back into, place. V- shaped bars 165, having rollers 166 mounted therein, are then placed in position upon the standards 150, these bars being supported at their ends in V-shaped grooves 167, which are provided in the inner ends of the extensions 151. These bars have to support comparatively litle weight and are therefore made light so that they can be easily handled without the danger of damage to the wire. The bars 165 having been placed in position the heavier tucks 152, which are adapted to support the entire weight of the forming section are then placed in position by being run over the rollers 166, manipulation of these heavy tracks being thus facilitated. Two temporary standards 170, shown in Fig. 4i-

c then placed to receive sections of track 171, which are similar to the tracks 152, and one end of each of which is supported by the fixed standard 150, the standard 170 being so positioned that the tracks 171 will be in alignment with the t 'acks 152. he shaking support 35 and the screw jack 160 are then lowered until the rollers 158 rest upon the tracks 152, after which the shaking ipport 85 and the screw jack are still further lowered so that the forming section is entirely free from these two parts, being supported entirely upon the tracks 1532.

The forming section or shaking part may now be moved bodily out of alignment with the remainder of the machine, and completely from within the wire which is hanging loose.

The old wire having been removed and the new wire placcd in position, this part then rolled back along the tracks 171 and 1,52 un til it is in alignment with the remainder oi the machine. The shaking support 35 and the screw jack .160 are then elevated to again pick up the forming section. This having been done the breast roll is then moved from its temporary supports hack into the jaw removed by being rolled along the rollers 166; after which the bars 165 carrying the rollers 166 are slid out of position. The "shaking support 35 and the screw jack 160 are then lowered to bring the forming section into the proper position relative to the rest of the apparatus. Oi course such other in- .c'idental parts as were neccssaril removed during these manipulations are replaced at for supporting the proper time so that the device will be entirely assembled. The parts having been thus reassembled the bars for retaining the save-ails against shaking are replaced and the device is then ready for operation.
