Application iledmprl 2S, 1.922. Serial No. 557,039.

To all fia/1mm t may concern:

lie it known that Winrar/rar H. ENGEL, a citizen ot the United States, residing at lifaukauna, in the county et utagainie and tritate oit lVisconsin, have invented certain new and useful Improve-ments in Papern liflalting ,liiachinea ot which the following a speciiication.

My invention has reference more partieniarly to the construction of a paper making machine of Fonrdrinier type so that the wire cloth on which the paper is formed may be removed and replaced without the necessity ol'A disniantling the machine.

rihc invention consist-s in the Yfeatures ot novelty hereinafter described, illustrated in the accompanying drawings, and particularly pointed ont in the claims atfthe end ot the speciiication.

(in the drawings:

Fig. 1 is a side view et approximately one-halt ot the length ot a machine embodyini;- niy in'iprovenicnt;

lilig. z2 a similar view ot' the other halt of lthe inachine;

Fig. 3 a top view or" the machine with the deokle 'trame and the top couch roll reino ve d Fig. i a view taken on the line L-d of Fig. 1 showing the breast roll` elevated at one side and the Fourdrinier wire in position to be inserted in place in the machine;

5 a sectional view on the .line 5 Fig. 2;

liigz t3 a fragmentary view partly in section on the line (3-6 ot' 5; and

l? 7 a side view ot the standard which supports the bottoni couch roll at the side ot' the machine opposite to that shown in Fig.

lileterring to the drawings, the reference ninnerals 1 and 2 indicate the main stand ards of the shaker section oi the machine. rlfhesc standards, which are alike, are located at opposite sides respectively oit the n'iaehine and connected together hy a tie rod 3. A. pair ott' parallel Lheains i and 5 which constitute the main supporting elements et' the shaker section have their corresponding ends pivoted respectively to the standards 1 and E2 as indicated at 6, and at their other ends arc supported by hangers i' on the overhanging portions oli the standards S. '.lhe hangers l are adjustahly connected with the liinitter more fully explained.

standards 8 so that the outer ends of the I-healns fiand 5 may loe raised and lowered to regulate the pitch of the Fourdrinier wire,

and they are also loosely connected with both the standards 8 and the I-hearns d and 5 in the nsual manner so that the customary side shake may loe imparted to the Fourdrinier wire for insuring even distribution of the paper pulp thereon. As the. side shaking movement is of very limited extent and is applied to the shaker section at the forward end, that is, the end of the machine at which the standards 8 and hangers 7 y are located, and as the shaker section is quite long, there is very little eifect of the side shaking action at the rear end ot the shaker section, and the pivotal connections (3 afford any looseness that may he required at this point.

lilach I-beain 4L and 5 has a pair oi standards 9 and 1() mounted thereon, the Aformer ot which are connected together' by a tie rod 11, and these standards together with the stainlards 1 and 2 support the superstructure ot the shaker section. Each standard 1 and 2 has an extension 12 horizontally pivoted to the upper end on a pivot pin 13, said pins being in axial alignment and permitting the necessary pivotal action of the shaker section super-structure when the hangers 7 are adjusted to raise or lower the 'forward ends oitv the I-beams 4i: and 5, and each extension 12 and each standard 9 and 1() has a hinge cap 14 secured to the upper end by bolts 15.

Extending along each side ot the shaker section is a top rail 17, each ot' which has spaced legs 18, 19 and 2O connected hy pivot pins 15 with the hinge caps 14 of the standard extensions 12 and, standards 9 and 10 respectively, the three pivot pins 16 at each side ot the machine being axial alignment. This pivotal connection alongl one side of the machine is provided so as to permit the super-structure ot' the shaker section to he iitted at the opposite side tor the purpose ot inserting a new `Fourdrinier wire as here- The corresponding pivotal connection at the other side is not required tor this purpose, hut is provided so as to afford uniformity of structure at both sides ot the machine whereby the wear occasioned hy the shaking of the section will be the saine at hoth sides ot the machine.

Each top rail 1? has a plurality et deseading hangers 21 which support another rail 22, the latter being, adjustable on the hangers 21 by means ot' the adjusting screws and these rails 22 which are located at opposite sides of the machine, have a` series oi closely arranged corresponding, bearings 2st in which a series et table rolls 25 are journaled. Mounted under the table rolls 25' are a series of save-all pans 2G which are carried by hangers 27 depending from the tOp rails 17, and also by suitable brackets 28 on the legs 18 and 20.

Beyond the standards 1 and 2 and spaced at opposite sides ot the machine are standards 29 and 30, the former or which has an extension 3l pivoted thereon on the pivot pin 32, and beyond the standards 29 and 30 and. suitably spaced therefrom are the standards 33; and 3a located respectively at opposite sides ot the machine, and the standard 33 also has an extension 35 pivoted thereon on the pivot pin 36 in axial alignment with the pivot pin 32. rlhe standard 30 entends upward'to a higher elevation than the extension 31 ot the stanoard 29 and has a short support 37 secured thereon by bolts 88, while the extension 31 ot the standard 2) has a somewhat longer support 39 secured thereon by bolts 10, and these supports and 39 are connected together by the tie rod Posts 42 and 113 are bolted on the enten-sie r 35 and standardv 3a respectively and extendL upwardly therefrom, as shown in Fig. 2, and

r there is a top rail la at each side of the niachine, one ot which has the opposite ends secured respectively to the support 39 and the post 42, and the other of which has thev positie ends secured respectively to the support 37 and the post 13. These rails are arranged in parallel relation and 'forni substantially a continuation ot the top rails 14' but are inclined downwardly troni the ends of the latter', as shown in Fig'. 2. Hangers 45 extend, downwardly from the rails and carry suction boxes 11G and these rails also have corresponding,` hangers-it? carrying,` the guide roll 118. A wire guide boi: L/l-S) is bolted to the posts 42 and L13 at one side thereot, and at the opposite sides oll these posts, bearings and 51 are secured by bolts and 5st to the extension 35 and standard 3l respectively and have the bottom couch roll journaled therein The post 13 and bearing 51 are not bolted directly to the standard 311, but are secured to a pleite 114- as shown in Fig'. .7 by the bolts 115 which have their heads seated in recesses .in the underside ot the plate, and the bearing` 51 also has a flange 116 at the side which is bolted to a flange ot the post 13. his structure is assembled in this manner to ai'iordv a i ,1, d construction of the rail le-fl with the bearing,` 51 for lifting the suction boxY section oit the machine by means of a lever applied to the end ot the shaft 103 as hereinafter more fully explained, and `this assembled structure is detachably secured to the top of the standard. 34 by the bolts 54.

it the forward end of the machine the legis 2O are formed with bearings 56 in which tl e breast roll 5'? is journaled, and the Fourdrinier wire 553 is engaged at the opposite ends over the breast roll 57 and the bottoni couch roll 55 respectively, and has the upper length passed over the table rolls 25, suction boxes 26 and the guide roll 48. ,fr pair ot guide rolls 59 and 6G are mounted in bearings 61 and 62 respectively on, the L beams 11 and 5 to support the lower length of the Fourdrinier wire, and beyond the shaker section are a pair ci' wire carrying rolls 53 and 6s which are mounted in bearingl standards 65 and GG respectively which latter are bolted to the floor upon which the machine is mounted,

A stretch roll GT is mounted between the guide rolls 59 and GO on a pair ot links 68 at opposite sides respectively ol the inachine, and these linhs are pivote'd at their upper ends to a corresponding' pair of links (S9 which are pivoted at their upper ends to brackets on the top rail 1T so that the stretch roll (ST is tree to drop down onto the lower length of the Fourdrinier wire 58, said roll. being of suilicient weight to hold the Feurdrinier wire stretched at the required tension for proper operation thereo' ln reino ig the Fourdrinier wire the stretch roll t?? is raised out of engagement with the lower length ot the Fourc rinier wire, and held elevated by hangers. or hooks 71 on the top rails 17, in which the ends et the shat't the roll 67 are eno'age'd, as indicated by dotted lines in rlhe declrlc trame which is ol the usual construction, is detachable from the machine and to this end is provided at each side with adjustable supports 73 having,l convex heads Tel at their lower ends, and the top rails l'i o2 the machine are provided with corresponding concave recesses 75 to receive the heads 74 olif the vdecirle traine supports 73 for properly positioning andv holding the deckle jrranie on the machine. By thus iorining the top rail 1'? with recesses to receive the heads Til, l avoid the presence of bolts and other projections above the rail 11"', which bolts or other projections would interfere with freely slipping,` the Fourdrinier wire sidewise over the rails and the rolls, etc., carried thereby. This decl-:lc traine has brachets i6 at the breast roll end ot the machine which supports sheaves or pulleys T7 around which the decirle straps 78 are paf-sed, the other end of these straps being; passed around sheaves or pulleys 'Z9 carried by brackets 8O which are bolted to the top rails 44. The upper length of the deckle straps letween the sheaves or pulleys T9 and the deekle trame 72 are supported by sheaves or pulleys 81 carried by brackets 82 which are secured by bolts or cap screws to the top rails 17, the lower length ot the deekle straps being; positioned to rest upon and adapted to travel with the upper length ot' the Fourdrinier wire 58 as it passes over the table rolls The ln'ackets 76 which support the sheaves or pulleys 7i' are secured to the deckle :trame by the bolts 83 and Sil, the latter being engaged in slots 85 et the brackets 7G so that the latter may be ose/i1 lated acont the bolts 855 il'or raisiing;` and lowering the sheaves or pulleys Ti', such adjustment being,` regulated by set screws 8G which are interposed between the end oit the bracket 70 and a flange 87 ol` the deckle trame.

it. top conch roll which is indicated at 88, bears upon the upper surface olf the Fourdrinier wire 58 as it passes over the lower couch roll 55, said roll 88 being journaled in a` pair oit braclets E50 at opposite sides respectively oil the machine, which are pivoted at 90 on the standard 0l so that the top conch roll 88 may be swungl troni the position out engagement with the llonrdrinicr wire to a position such as shown by dotted lines at 92 in Fig. 2, to aii'ord ample clearance between the couch rolls 88 and 55 when it .is 'desired to change the llonrdrinier wire.

llxtending' between the corresponding legs 18, 10 and 20 at opposite sides ot the machine and also between the supports Si" and 30 are channel irons 03 which have their ends at the le'lthand side et the machine, as the latter' is viewed in l, secured by bolts 911i to the respective supports 18, 19, Q0 and 39, and the opposite ends ol5 these channel irons are secured to the corresponding supports 18, 19, Q0 and il?, at the opposite .side ot the machine by an Lsshape'd clamp 05 which has one or more threaded arms ,inserted through 'the respective support, and secured thereto by nnte 00 which clamp the end oit the channel iron 03 in place and atiord an nnobstructct opening into the end oit the channel member. A liilter bar 97 ot suitable cross sectional term to iit therein provided iter each channel member 93, and each lilter bar has an arm or extension 98 piveted at 99 to the outer end thereof, which extension may be held in the extended position against pivotal movement by a locking pin 100 which engages apertures in the adjoining hinge portionsl et' the litter bar and extension respectively.

l have also provided lifting means tor the oljiposite ends ot 'the machine comprising similar socket members 101 which telescope onto the ends ot the shafts 102 and 103 ot the breast roll Si' and the bottom couch roll 55 respectively, said shafts being extended beyond their bearings at the right-hand side of the machine as the latter is viewed in Figa, so as to be engaged by said socket members, and each socket member has a lever or arm 104: pivoted to the outer end tl creol as indicated at 105, and theinterengaging hinge portions et the socket inem'- ber 101 and lever 104V are provided with apertures to receive a pin` 100 whereby the lsocket member 101A and lever l0-Ll are held in alignment and prevented ilrom pivotal movement.

1iifhen it is desired to change the Fourdrinier wire, the deckte trame is lifted from the machine and held at a distance above the latter so as to atii'ord ample clearance between the top ol the machine and the decklc iframe for inserting the new Fourd nier wire therebetween, and the bearing brackets 80 and 82 are nnbolted from the rails -lt and 17 respectively, and these brackets with their sheaves i9 and 81 are likewise lifted and held at a. snitable distance above the top ot the machine. rlhe ripper conch roll 88 also litted and held at a distance above the top ot the machine substantially in a position shown by dotted lines at 92, and the table board 107 which is hinged to the head boli: 108, as indicated at 109, is thrown back so that the entire top el the machine is lett clear 'tor the insertion oi a new Fourdrinier wide. The stretch roll 6i' is litted up and engaged in the hangers 71 as shown by dotted line in Fig. 2: the support nnbolted t'rom the standard 30, and the assembled bearing- 51, plate 'l1/l and leg lf3 unbolted from the standard Sli. rlhe three pivot caps 14 at the right hand side et the machine, as the latter is AViewed in Fig. 4, are also unbolted from the standards 9 and 10 and the extension 12 and the super-structure of the machine is then rear y to be li'tted for inserting' the new Fourdrinier wire. rihe old wire 58 may be removed at any time as it is customary to cut it, and this or course C permits removal oit same bel'ore the machine is separated at the side.

rlhe lifting bars 0i' are now inserted in the channel irons 93, and the sockets 101 inserted. on the ends ot the shatts 102 and 103, as shown in Fig. 3. The levers 98 and 104. are then swung inwardly to positions close against the side ot the machine, as shown by dotted lines in Fig. 3, atter which the new Fourdrinier wire is stretched out on the iioor alongside of the machine. The upper length et the Fourdrinier wire is then lifted and the levers 98 and 104 swung` outwardly to the position shown in full lines in Fig. 3, so as to support the new Fourdrinier wire, as indicated at 110 in 4;, and the locking; pins 100 and 106 are inscrted in place so as to hold the levers 98 and 101 in the out-turned position. The outer ends of all the levers 98 and 1011 are then connected to a hoist 111 and the hoist operated. so as to litt the outer ends oli all these levers simultaneously so that the upper portion of the machine swings on the pivots lll-16u16, 32 and 36 at the lett-hand side of the machine, as the latter is viewed in Fig. el, and the parts 14--1-1-14, 37, @i3 and 51 at the right-hand side of the machine are lifted away. from the parts 9, 10, 11, 12, 30 andv 34 at the right-hand side ol the machine, as shown in Fig. 4, so as to leave a gap therebetween through which the lower length of the new Fourth-inici' wire 110 may be readily inserted. The new Fourdrinier wire 110 is then pushed laterally into the machine with the ends engaging around the breast roll 57 and the bottom. couch roll 55 respectively, and the upper length engaged over the table rolls 25, suction boxes land guide roll 4:8, while the lower length ot the new F ourdrinier wire is inserted between the separated parts of the frame, under the table rolls Q5, save all pans 9.6, stretch roll 67, suction boxes 46, guide roll 48, wire guide box 49 and other parts of the top of the machine, said lower length being inserted over the wire carrying rolls 59, 60, 63r and (S- After the new Fourdrinier wire has been :t'ully inserted, the hoist 111 is operated to lower the outer ends of the levers 98 and 104; so that the members 14-1-1-14, 37 and plate 114 of the assembled bearing` 51 and post t3 rest again on the respective parts, whereby they are supported, dowell pins 112 being` preferably provided on these parts to insure return of said parts to the proper position, and the parts 14-14-14, 37 and 114 are then bolted downk in place. The lifting members 9S and 10d are then removed, the table boa-rd 107 laid down in position and the top couch roll released and lowered into the operative position. The deckle frame 72 is lowered into position with the convex heads 74 ofthe supports 73 engaged in the concaved recesses 75 and the sheaves 79 and S1 are lowered and their brackets 80 and 82 bolted in place on the side rails 4st and 17 respectively. The stretch roll (S7 is then released from the hooks 71 and lowered onto the lower length of the Fourdrinier wire between the rolls 59 andl 60, thereby imposing the necessary tension on 'the wire and the machine is now ready tor operation.

From the foregoing it will be observed that theireplacenient of the Fourdrinierwire is effected without disturbing the table rolls, suction boxes, save all pans, breast roll, lower couch roll, guide roll and various other parts which it has been necessary hereto't'ore to. remove when it is necessary to replace the wire, these parts being` merely lifted with the upper section of the frame to insert a new wire in placey after which the upper section ofthe frame-isbolted back in place.
