My invention relates to paper machinery, having particular`V relation to those parts .which are directly associated with thewire..`

vof Fig. 1,;

One object of myinvention is to provide a Fourdrnier-part comprising inde lendently removable ,table-roll and suctionox sections. Such construction permits the re-v lacement of the wire in one-third the 'time eretofore considered, practical and' with,` f a corresponding decrease `1n maintenance charges. It also makes possible the removal of the structure by hand, thereby eliminat-` ing the necessity for the expensive poweractuating mechanism embodiedAAV in theprior 1.5 art machines.

Another object of my invention to provide apparatus of the class described, wherein; the removable Fourdrinier part may be lowered from an upper workingpositiomto a lower position in engagement Withmean's adapted to facilitate the removal of .said part. l.

A further object of my invention is to 'provide ower means for raising and. lowering. part between the working., .and removing positions, the power means also the ourdrinier serving to .operate the couch roll' longitudinal-ly of the Fourdrinier part, so tha `wiremay -be draped in laceto give ample clearance for inserting t e removable parts,

without injury'to the wire'. v l i A'still further object of my invention is `to provide a'Fou'rdrinierpart comprising hinged sections adapted to cooperate with a wire, and power means whereby the'pitch of said wire may be adjusted at an intermediate point. v Y' A still .further object of my invention is to provide a bodily movable Fourdri-nierpart characterized by maximum vibration at the v breast roll end thereof.

Withthese and other objects and applications-I in mind, my invention further con-v sists in the details of construction and operation and arrangement, -hereinafter described 4 and claimed and illustrated in the accompanying drawing, wherein Fig. 1 is a side elevational view of a paper making machine embodying my invention;

Fig. `11 is a to plan view of one of the gearboxes kwith t e cover-removed.

Referring to the drawing, the paper-making machine thereindisclosed comprises broadly a head-box 1 having` a so called.

voith inlet 2 positioned to discharge onto a breast-roll and?) of a wire' 4 supported by a removable Fourdrinier part 5, -vthe pul being 'finally transferred -from a couch-rol end'6 of they wire 4 to the usual drying rolls `(not shown).

-Th'e Fourdrinier part 5which embodies the principal features vof my invention, com-A rises a removable table-roll section 7, and independently removable contiguous suctionbox section 8, anda suction or coueh'roll 9 bodily movable onjways 11 extending'longitudinallyof the wire 4. n

Considering the table-roll section 7 in greater detail, a pair of longitudinally extendingside table-rails` 12 and 13 are providedwith bearings 14 for the support o the usual table rolls 15. The rolls 15 togetherconstitute an upper workingsurfacepl providing a support for the Fourdrinier wire 4. According to my invention,a rear or couchlioll end 17 of the rails 12 and 13has pivotal -mountings 18 .and 19 which are respectively supported on adjacent rear ends 21 of side portions 22 and l23 of a supporting frame 24.

Each of the mountings or'bearings 18,19

comprises a vertical trunnion pin 25 which extends upwardly through the adjacenttable rail from a horizontal bearing surface 26.

The rail-supporting surface 26 is formed on an upper side 27 of a longitudinally extending member constituting one of the

side frame portions

22, 23. The vertical trunnion pin 25 and the bearing surface 26 thus permit a limited horizontal vibratory movement of the

table rails

12, 13, and rolls 15,-this movement being substantially negligible at the couch-roll end 17, but a maximum at the breast roll end 3 of the Fourdrinier wire.

The side portion 22 of the supporting frame 24fcomprises rear and front box-

like end sections

28 and 29 respectively, upper sides 31 of which are interconnected by an angle 32 posltioned directly beneath but in spaced relation to the adjacent table or shake rail 12. The angle 32 at spaced points intermediate the ends/thereof is provided with downwardly extending

angle sections

33 and 34 which are secured to a reinforcing angle 35 having a horizontal section 36 positioned intermed1ate the depending sections 33`and 34 and end sections 37 and 38' respectively extending upwardly to the adjacent sides of the box-

like sections

29 and 28. The opposite side portion 23 embodies similar horizontal and vertical reinforcing angles 39 and 41 and enlarged rear and

front end sections

42 and 43. The

rear box sections

28 and 42 are interconnected by an angle 44, while the

front box sections

29 and 43 are interconnected by an angle 45.

The lower ends of the

vertical angles

33, 41 and 34 may be connected by

transverse angles

46 and 47 respectively.

The

table rails

12 and 13 are interconnected adjacent to the verticall angles 34 and 41 bya shaft 48, each end of which is provided with a in 49 which extends upwardly through the adjacent rail and terminates in a supporting head 51 in the form of a supporting bolt head or nut, a similarly supported shaft 50 extends between the vertical angles 33 and 41.

As shown in Fig. 8 the portion of the

rails

12 and 13 respectively adjacent to the vertical angles 34 and 41 may be supportedby a pair of resilient devices 52 permitting lateral vibratory movement about the

pivotal mountings

18 and 19. Each of the devices 52 comprises a pair of spring strips 53, the upper ends of which are bolted to flanges 54 extending from opposite sides of the shaft 48. The lower ends of the strips 53 `are mounted on flange 55 extending from opposite sides of the transverse angle 47. The portions of the

shake rails

12 and 13 adjacent to the vertical angles v33 and 41 respectively are similarly supported for lateral vibration by means of

resilient devices

56, 56.

The table rails`12 and 13 may be further supported adjacent to the breast roll end 3 of the wire 4 to afford the desired lateral vibratory movement by means of a pair of

pedestals

57 and 58, respectively. These pedestals extend upwardly from a supporting floor surface 59 to

bearings

61 and 62 respectively secured to adjacent flanged ends 63 of the

shake rails

12 and 13. The

bearings

61 and 62 serve to support shaft 64 carrying a breast roll 65 around which the wire extends.

As illustrated in Fig. 9 each of the

pedestals

57, 58, comprises a base 66, a block 67 which is removable secured thereto by bolts 68, and a spring structure 69. `The structure 69 includes a pair of spaced strips 71, the lower ends of which are secured to opposite sides of al bracket member 72 secured by bolts 73 to the removable block 67. The upp'er ends of the spring strips 71 are spaced by a member 74 pivotally mounted thereon by pins 75. The member 74 is provided witha central recess for the reception of a tongue 76 extending downwardly These parts may be pivotally connected together y a pin 75. Such mounting` permits the breast roll and connected shake rails 12- and 13 to move in a vertical plane about the spring structure 69 without interfering with the V.lateral vibratory movement thereof. It will be noted that the

pedestals

57, 58 serve to support the breast roll 65 and adjacent ends of the

shake rails

12 and 13 independently of the main supporting frame 24, the latter in turn supporting the intermediate

resilient devices

52 and 56, 56 aswell as the vertical

pivotal mountings

18 and 19 at the couch-roll end 17.

My invention also contemplates the hingin of the frame 24,-whereby the couch-roll end 17 may be moved vertically to adjust the pitch of the wire 4. To`this end, a pair of supporting

pedestals

78 and 79 are positioned directly below the

front box sections

29 and 43. Each

p'edestals

78, 79 comprise a bracket 81 extending upwardly from the base 66 and a removable bearing block 82 embodying the lower half 83 of a pivotal bearing. 84, an upper half 85 of which is formed on a bracket 86 secured to an underside 87 of the

box section

29, 43.

T heslearing parts

83 and 85 embrace a pivot pin Such vertical adjustment of the frame 24 about the pivotal bearings 84, 84 as may be necessary to establish-the desired pitch of the wire 4 may be effected at the couch-roll end 17 by power means 89. The power means 89 comprise a ,pair of spaced screw- ]ack devices 91 and 92 positioned directly beneath the rear box sectlons 28 and 42, respectively, on thefloor surface 59. The devlces 91 and 92 are interconnected by a com- Imon cross shaft93 extending to a gear box 94 having a control element 95. The ear box 94 is connected to a main operating s aft 96' extending longitudinally of the Fourdrlnier part 5. The main power shaft 93 is driven by a motor 97. As shown, the gear box 94 is so constructed that when the control element 95 is in one 93 is connected to the main-power shaft-96 to operate the screw jacks 91 and 92 in one direction. When the contact element-95 is from the adjacent bearing.v

position, the cross shaft v movedinto 4another position, the screw jacksA l 91 and 92 are operated in the reverse direction ofv movement into an intermediate poprises a post 98, a lower end of which carriesV a wheel 99 which meshes with a worm '101 on the cross shaft 93. The post 98 may be guided'by means of acasing 102 tor movement into and out of engagement with a spherical recess 103 formed in thelowerend of ablock 104 mounted ontheunderside of the rear box y sections 28 42. The upper end of the post 98 is Jformed wit-ha surfacev complementary to that of the Arecess 103. When it is desired to 'adjust the pitch of the table rails 12 and 13,' the control element 95 is moved into the position causing'the desired vertical movement of the post 98and hence the frame 24 about the pivotal mountings 84.

My invention still further contemplates the lowering of the table-roll sectionf7 from the-upper working position of Fig. 1 to the lower position of F ig. 2' wherein the frame 24 and associatedv parts may beremoved from the machine to permit the replacement of a damaged or Worn out wire. Accordingly, I provide power means 1-05 at the hinged front end of the frame 24, said power means constituting supports auxiliary to the bearings 84, 84, permitting the removal of the blocks 67 andy82 and, thereafter, in combination, with the power meansl 89, the lowering of the structure 24` into the desired position, as

will presently appear.A -The power means 105' comprises a pair of screw-j ack devices 106 and 107 corresponding to the devices 91 and 92,. Each of the devices' 106, 107 includes a vertically movable ost 108, the upper end of which is movab e into engagement with the' bearing bracket 86, while a lower end is provided with a wheel 109 in mesh' with a worm 11.1 on a cross shaft 112. The shaft 112 is connected to a gearbox 113 corresponding to the gear box 94. The gear box 113. is provided with a control element 114 having raising, lowering and neutral positions, as in the cas/e of the control elements 95.

The rposts 1-08 may be inclosed in a housing 115 which forms a part of thepedes`

tals

78 and 79. 1 The housings 115 are provided witlraligned recesses 116 for the reception of removable Lbeam rails 117 that extend transversely of the machine into the side aisle. The casing 102 for the screw-jack devices 91 and 92 is also provided with aligned recesses 118 for the reception of removable rails 119 extending into the side aisle of the machine. The movement of the :trame 24 over these rails may be facilitated by wheels121, ofwhich four are shown, two being `respectively mounted on the side frame portions`v22 and y23 adjacent to the breast roll 65 and the remaining two being 'similarly mounted at the rear end of the The further vertical movement of the po'sts 108 cause adjustable frame abutments to en' gagethe flanged ends 63 of the shake rails 12 and 13, respectively, causing the load carried by the breast-

roll pedestals

57 and 58 to betransferred to the posts 108. The front and

rear posts

108 and 98 now support the frame 24,:the breast-rol1 65, table rolls 15 andv rails 12 and 13, permitting the

blocks

67 and 82 to be removed.

The. control elements 95 and 114 are now moved in-to their lowering position, with the result that the

posts

108 and 109 move downwardly, dropping the table section 7 from its upper working position to its lower position wherein the wheels'121 engage the rails 117 and 1118. Thetable section 7 may .now be moved laterally of the machine'into the side aisle. Such movement occurs independently of the suction-box section 8.; I

The suction-box section 8 has a rear end 125 thereof pivotally mounted on bearings 126 provided Y by-fspaced pedestals 127 respectively, positioned at the opposite sides of the section.v Each of the pedestals 127 includes a removable bearing block 128 corresponding to the removable blocks 82 associated with the pedestals78 and 79 in the table section 7. A front end 129 .of the suction-box section 8, which is adjacent to the rear end 17 of the table '

rails

12 and 13, is supported `on power means 131 comprising screw-jack devices 132identical with those for the table-section 7. The devices 132 are intereonnectedby acommon shaft 133 leadjing to a gear box 134 having an operating element 135 for controlling the connection between the shaft 133 and the main-operating shaft 92.

Should it be desirable to change the pitch of the wire 4 independently of or in conjunction with the table section 7, the control element 13.5 is operated'into its raising position, wherein `the main shaft 96 is connected to cause the devices 132 to move vertically the front end 129 of the suction-box- 8.v Such movement occurs about the pivotal bearings 126. Additional power means 136 corresponding to the table power means 105 may be provided adjacent to the pedestals 127, and it comprises a pair ot' screw-jack devices 137 having an inter-connected power shaft 138 extending to a gear box 139 controlled by an element 141.

The front and rear screw-

jack devices

13 and 137 have recesses 142 in their casings for the removable reception of front and rear rails 143 and 144 adapted to co-operate with wheels 145 carried by the suction-box section 8. IVhen it is desired to remove the section 8, the control element 141 is moved into its raising position, causing the rear screw-jack devices 137 to lift the suctionbox end 125 from the bearing pedestals '127, whereupon the blocks 128 may be removed. The control elements 135 and 141 are then actuatedinto their lowering position, permitting the screw-jack devices 132 Aand 137 to lower the suction-bex section 8 from its upper working position to a lower position wherein the wheels 145 engage the rails 143 and 144. The suction-box section 8 may now be removed from the machine into the side aisle.v

A still further feature of my invention is the provision of means, whereby the suction roll 9 may be movedupon power backward from the running position to give slack to the wire 4. As shown in Figs. 1, 2 and 3, such construction involves the mounting of the oppositeends of a couch-roll shaft 146 on bearing pedestals 147 and 148 which are respectively supported on the ways 11 extending longitudinally of the machine. Each of the ways 11 is providedwith a central recess for a screw shaft 149, one end of which extends into a threaded portion of the pedestals 147, 148. An opposite end of the screw shaft 149 is geared to a transversely extendingr shaft 151 which terminates in a gear box 152 having'a control element 153. The gear box 152 is connected to -t-he main operating shaft 96, as in -the preceding gear boxes, and it is A of similar design. I When the element 153 is actuated into one position, the pedestals 147 and couch-roll 9 are actuated to slacken the wire 4, but when said element is oppositely actuated, the couch roll 9 is moved to tighten the wire 4. l 1

Assumingl the table-roll section 7 and the suction-box section 8 in ltheir laterally removed positions in the machine aisle and the suction roll 9 moved backafording a maximum slack in the wire 4, the Fourdrinier part is in the position permitting the removal and replacement of the wire 4. When a new wire 4 is positioned in the machine, the table-roll and suction-box sections 7 and 8 aremoved on their supporting rails into correspondingly A is then reversely operated to cause the front posts 108 to move downwardly, permitting the load of the breast-roll and adjacent table-

rolls

12 and 13 to be transferred to the

pedestals

57, 58, and the lead of the front end of the frame 24 to be assumed by the bearing pedestals 78, 79. The suction box section 8 is similarly returned toits original position shown in Fig. 1, and the suction roll 9 is then moved forward by the power shaft 96 through the gear box 152 to running position. The pitch of the wire 4 is next adjusted by the

posts

98 or 131 or both.

lVhile I have shown only one form of embodiment of my invention, for the purpose of describing the same and illustrating its principles of construction and of operation, it is apparent that various changes and modifications may be made therein without departing from the spirit of my invention, and I desire, therefore, that only such limitations shall be imposed thereon as are indicated in the appended claims or demanded by the prior art.
