Fig. 10 and track Fig. 10;

Figs. 11 to 23. inclusive. are views of details of construction.

llelerring to the drawings. and especially to Fig. 1. we show a l ourdrinier machine having a table supporting rolls 1. over which the wire 15 extends and travels. The table is mounted on pedestals or posts 2. 3. 4. 5 and (3'. whereof the pedestals 2 and G are at the lelt and right hand ends of the machine respectively. and the pedestals 3 and 4 are located at intervals between the ends. A deckcl strap 7 is shown mounted on wheels 8 and 9 having its lower portion 10 resting on the upper stretch of the wire B and its upper portion 1] mounted on standards 12 and 13. A breast roll 14 is shown at one end of the machine for supporting one end of the wire and couch rolls 15 and 16 at the other end of the machine.

In accordance with our present invention the table A is moved or shifted transversely to its length or it may be said transversely to the direction of motement of the wire B, at a time when it is desired to remove and replace a wire. Certain elements of the machine have to be lifted out of the way to permit this transverse table movement. Other elements have to be adjusted or changed in various ways as will be particularly pointed out hereinafter. Suitable provision has to be made for the support otthe table when it is drawn or moved as described, and arrangement has to be made for putting a new wire in place. and then pushing the table back to its normal position. adjusting the wire and the various parts and elementsQso that the machine normal condition is an end elevation of one post 01 the machine. as shown in described hereinafter.

As an arrangement for permitting the All this will be in Figs, 3 and 1. In this arrangement there are shown 'two sets of beams 18--18 and 1919. the former of which will be called the back channel tracks or beams and the latter the front channel tracks or beams. These heams are not normally in the p0sitions shown in Figs. 3 and 4,'n 0t normally beingin a Sense a part of the'machine, but

are put,into position preliminary to shifting the table to change the wire. Each of these beams 18-and 19 is preferably'made in the form of a pair of channel beams 20 and 21. as shown in Fig. 8, spaced apart by into the positions'shown, a rear track 18 and a front track 19 for each pedestal 2, 3, 4, a and 6. The front tracks 19 are longer than the rear ones 18, so that the former extend well through the front posts or pedestals 2, 3, 4, etc, and are fitted to the rear oncslS by fmeans of parts (Fig. 10),. secured on the tracks 18 and fitting into sockets in the tracks 19. I I

As a means for holding the front ends of the front tracks 19 there are shown supplemental or temporary posts or pedestals .27-

(Figs. 10 and 10) which as shown in Figs. 3 and 4, are placed at the front or outer ends of the tracks 19. These members 27 are preferably in the form of simple cast pedestals having their lowcrends provided with pins 28 to fit into apertures in the floor and having their upper ends provided withscrews 29to adjust the height of the tracks 19 thereon. The tracks 18 are provided with stops 29 for checking the back movement of the table and the tracks 19 are provided with stops 30 for checking the forward movement of the table. To permit the latter movement of the table. it is provided with rear wheels 31 and front wheels 32, (Figs. 3,4, 8 and 19), the rear wheels 31 being arranged to travel on the tracks 13 and the front wheels 32 to travel on the tracks 19. \Vhe'els 31 and 32 are enclosed in housings at joints of table sections, Figs. 8 and 10 Shafts for said wheels are mounted on opposite ends of adj aecnt table sections.

As an-arrangement for driving said wheels or certain of them, a driving shaft 33 (Fig. 8) is mounted on the table and extended lon'- gitudinally thereof substantially from end to end of the same, as shown in Fig.1. Bearings 34, for the left hand end of said shaft 33 are shown more clearly in Fig. 6, intermediate bearings 36 and 37 'in' Figs. 7 and- :8, respectively, and right hand end hearings in Fig. 9. The drive-shaft 33 is provided with pinions 39 and the table wheels 32 are provided with rack teeth 40 meshing with the pinions 39 whereby the rotation of the shaft 33 will rotate all of the wheels 32 and thereby cause the table to be shifted laterally-one way or another on the tracks.

18 and 19, according to the direction the shaft 33 is rotated.

As a means for rotatingthe drive shaft 33 weshow a motor 42,- (Fig. 7) which may be an electric motor mounted upon andcarmotor 42 is connected through gears 43 and .44 with a drive shaft 45 which. carries a worm 4(5 meshing with a worm wheel 47 (Fig. 10) on the main longitudinally extending drive shaft 33. Thus by the operation of the motor 42 and its train of mechanism the drive shaft 33 may be turned in one direction or another, and the table A shifted latcriilly. one direction or another, according to the direction of rotation of the motor. As an arrangement for adjusting the table A to permit it to be lifted slightly to allow of its lateral motion, we provide lifting devices which are capable of lifting the tracks 18 and 19 slightly and thereby not only adj-ust-' 'ing said tracks .upwardly against the table wheels 31 and 32, but also adjusting said tracks upwardly .to an extent to lift the .table slightly from the posts. or pedestals 2, 3, 4, etc. These lifting devices which are best shown in Figs. 7 and 10, comprise lifting screws 5()-5(), one for .eaeh post or pedestal, a'nd cams 751, on rock shafts 52 controlled by levers 53, the lifting screws 50 being provided with socket members 54 mterposed between them and the cams 51 and resting on the latter. The upper ends of these screws 50 are provided with plates 55 which fit against the lower surfaces of the tracks 18 and 19 and between lugs 56 and 57 thereof, so that a swinging movement of the levers 53 willeause the screws 50 to push upwardly against the tracks 18 and 19 and "thereby liftthe same. This lifting actionis very slight bun sufficient to cause the tracks 18 and 19 to contat with the table wheels 31 and 32 and to pushthc same 11pwardly to an extent to lift the tableslightly up from the pedestals 2, 3, 4, etc. The lift ing screws 50 may be adjusted to certain extents so as to cause them practically to contact with the tracks 18 and 19 before the levers 53 are swung, by turning the threaded sockets 54 relatively to said screws 50.

-Thusit will be seen that the rails 18 and 19 may be put lll position, as shown in Figs.

3, 4 and 5. and then the levers 53 on the pedestals fl 3,- .4, etc... may he turned so as to lift thetahle A slightly 1111' from said pedestals and then the motor 42 may he started, turning the wheels 31 and 32 and causing the table to move on the tracks 18 and 19, direc-. i

tion of rotation of the motor being such as to cause the table tomove to the left, (Figs.

3 and 10) so that it will move from the position shown in Fig. 3 to the position shown in Fig. 4. f I v There are also other parts" or elements of the machine which must be taken care of in this movement and" explanation of these will now be made, I

One of these element; i the deckel Strap 7 and its supporting wheels 8 and 9. in connection withthesame the pond walls 60, Figs. 1 and (3. These parts are intended to be lifted by cranes which may engage the wheels 8 and 9 and lift the same above their normal positions, as shown in Fig Z. The pond (S0 is also lifted and the construction by which this is accomplished will now be explained. This pond 60 which is best shown in Figs. 6, 17, and 18, is arranged at the side of the head box 61 and is secured thereto in such manner to permit the pond (30 to be raised relatively to the box (31, as shown in Fig. 2. To such end the front and rear walls of the pond. the front wall or plate (53 being shpwn, (Fig. 17) are secured to the adjacent wall (51 of the box (51 by means of clamps (55 (Fig. 17). One end of each clamp (Sirestsand acts upon an angle bar 66 secured by bolts (37 to the plate (33 and the other end of each clamp (35 contacts with and acts against a vertically extending strip (38 which is secured as by bolts (30 to the outer side of the tank wall (34. The clamps are held in position by bolts 70 passing through them and into the strips "68. 'Each clamp (35 has a slot 71 permitting it to have a certain amount of play or longitudinal movement with reference to the bolts 70, and the strips (38 are provided with different apertures 72 into any one of which a bolt ;70 may be placed in order to allow a further extend of longitudinal adjustment of the clamps 05. By loosening the bolts 70 the box (51 is bodily elevated. In this connection it may be notedthat the forward and back adjustment of the wall or plate 63 is permitted by loosening the clamps 73 so as to permit the sleeve 74 to slide on the cross bars or rods 75 and thereby permit the wall (33 to be moved laterally as desired to accommodate different widths of paper to-he made by the machine, the position of the plate (53 detern'iining the length of the slot or opening 76 (Fig. (3) through whichythe pulp or material from the pond is fed on to the wire.

This transverse movement of the plate (33 is accomplished by means of a crank handle 77 (Fig. '17) which turns the shaft 78 carrying a gear 79 which meshes with a gear 80 on a shaft 81 which extends upwardly and diagonally across the front of the tank, as shown in Fig. (L and has its upper end provided with a gear 82 meshing with a. pinion 83, on a rotary sha'ltti4. 'lhe shafts TS and 84 have threaded ends 78' and 84, respec tively. which engage with the-plate (33 or parts thereon, and so adjust said plate laterally when said rods 78 and 84 are turned by the rotation of the crank handle 77. The deekel wheel 8 is mounted'on the plate 63, as shown in Fig. 18, the axle 8 of the same having an extension 9" passing through the tits in a slot 90 by which the wheel 8 may be adjusted vertically. (Figs. (3 and 18). Thus the deckel wheel 8 will move with the pond 60. In order that the upper cross shaft T5 may rise with the pond (30, the bearing 01 for the same is made open so that said shaft may be lifted bodily out, of said bearing. thereby pern'iitting it and all of its connections to leave the bearing and go with the pond and associated parts. The bearing $10 is so located as to permit the pond to swing upwardly about the shaft 75 as a pivot. The other deckel roll 9 will be lifted bodily from its bearings 93(Figs. 19 and 20) by releasing said screws 94 which screw into the upper parts of said bearings 03, the latter being open at their upper ends or U shaped. as best shown in Fig.10. The set screws 04- hold the shafts 0 of the deckel wheels 0 in proper position in the bearings 92, until it is desired to lift the deckel strap and associated parts, in which the screws 01- will be undone, thereby permitting the shafts 9 to be lifted out of the bearings 03, and the rvheels 9 to be lifted bodily by cranes or otherwise with the docket straps T thereon. .For longitudinal adjustment the bearings 93 are shown mounted on cross heads 95 which are arranged for sliding movement in standards 96 secured in position by screws 97, said movement being accomplished by rotation of a screw 98 having a hand wheel 99. In this way the deckel strap and its pulleys together with the pond and associated ,lifted bodily, as shown in Fig. 2.

Arrangement is also made for adjustment of the couch rolls 15 and 16 to permit the re.- moval of the wire. To such end the upper couch roll 16 is mounted on swinging frame members 100 (Figs. 1, 0 and 15). each of which is adapted to swing upwardly and backwardly about a pivotal connection"101 located'at the upper end of a base or body member 102 mounted on the floor close to but separated from the endniost post or pedestal I (3. The member 100 is provided with a pro- 109 on the member 102. By undoing the nut 108 the rod 104 may be released, thereby per mitting the member 100 to be swung up 1 wardl'y to-the elevated 15. a A swinging bar 110 is pivoted on the pro ection 109 at 111, and is in engagement with the nut 108. so that said pivoted bar 110 will exert downward pressure on the rod 104,

parts, may be position shown in Fig.

with a projection 120 subject to pressure of toreceive said dowel pins. The block 123 on tending to hold the roll 16 downwardly on the wire B. A weight 112 is mounted on the bar and arranged to slide on the same so as to adjust the pressure exerted by the rod 10-1. -The couch roll 16 is provided with a scraper blade 113 mounted on a block 114 which is adjustable by means of a screw 115 having a wheel 116 and a stop nut 117. The board 114 is mounted on an adjustable member 118 pivoted at 115) on, the end of the .member 101) and said member 118 is provided a spring 121. which surrounds a rod 122 an 1 is subject to the adjustment of a rotary nut 123, whereby pressure may be exerted on the scraping blade 113. The rod 122 is pivoted at 124 and a smaller and weaker spring 125 is located between the pivot 124 and the member 120 so as to lift the member 120 when the pressure of spring 121 is reduced or released. I This blade 113 with all its associated mechanism -1S lifted bodily and swung upwardly when the member 100 is swung lip-- wardly to lift the couch roll 16. The lower the front side of the machine.-that is the .nearest side looking at the machine as in Fig. 1, is pivotally mounted by meansof a pivot screw 131, whereby said block 123 may be swung about said pivot to the right rel'erring to Fig. 9. sothat it will come into position at the right haudside of its usual position, as shown in Fig. 15. In this way said block 123 may bemoved out of the way of the wire ll so as to permit the latter to he slipped on or oil from the roll 15. The other or rear beariug 127 for said roll '15 is per manently secured to its block 128', Fig. 16), and the latter is secured to the base. member 1H2. as by s-rews 132; 'lheupper-part 127' ofthe back bearing 127. however is simply pulled down, so that it may be removed and permit the rear end-of the axle 15' .of the couch roll 15 tobelifted out of said bearing 127." In this waytheuppercouch roll 16 may be swung upwardly and bachwardly entirely out of the way and the lower couch roll 15 may have the wire pulled over it and may be lifted bodily upwardly and to the left. so as to give the wire slack, as shown in Fig. 15.

Another the wire tightener 135, best shown inFigs.

1, 8, 21, 22 and 23. This wire tightener comelement to receive attention is prises a roll 136 adapted to rest upon the wire 2 and tighten the same. The roll 136 is mounted in bearings 137,1which are secured to and suspended from sleeves 138 and mounted on vertically arranged adjusting screws 140. These screws 140 are provided at their upper ends with .mite-r gears 141 which mesh with pinions 142 mounted on the opposite ends of a rotary shaft 143 (Fig. 21). A hand wheel 144 controls the shaft 143 so that by turning the hand wheel 144 the pinions 142 will turn the screws 140 and there by cause the sleeves 138 to be raised and lowered so as to raise and lower the roll 136 and thereby vary the pressure applied by said roll to the wire B. The hand wheel 144' is atthe front end of the shaft 143, as shown in Figs. 8 and 21.

Arrangement is made so that this tightening device may be swung to'one side, preferably upwardly and to the left, referring to Fig. 8, so as to lift the roll 136clear of'the wire B, and alsoso that the screw 140 maybe out of the way to permit movement of the table relatively .to the wire. In the arrangement shown,,the shaft 143 serves as a pivotalmounting for the screws 140 and associated parts, and to temporarily hold the wholea-rrangement in position. A clamp or connection 147 is shown between the lower end of the bracket or frame 148 and the side 5 of the'post or pedestal 5, said bracket 147 being secured to the flange 51 by bolts 149 and to the standard or upright 148 by bolts 150. To

the bearing 151 bolted to the lower end of the frame 148 and serving as a support and bearing for the lower end of the screw 140, is attacheda-rope or flexible connector 152 which extends upwardly and around a rotary shaft 153 suspended by abearing 154 from the table A, whereby by the rotation of said shaft v153 the flexible connector 152 may be wound on the shaft 153. and the tightening device 135 may be swung upwardly and to the left, referring to Fig. 8. The shaft 153 maybe turned to accomplish this by means. of a hand wheel 156. A cog or ratchet arrangement is provided consisting of a cog wheel 157 and a pivoted dog 158 by engaging the cogs on wheel 157 and thereby holding said shaft 153 in any adjusted position. By this arrangement the tighteningdevice as a whole may be swung upwardly and to the left and held in said elevated position, practically horizontal if desired.

Onthe table A there is another roll 160 mouute dfat its right hand end onthe bracket 161, as shown in Fig. 9. This roll supports the wire 2 and being mounted on the tab e A."moves with it. Another roll 162 isar ranged below the roll 160 and mounted on a bracket 163 on the endmost post or'i'pedestal 6 as shown in said Fig. 9. .This 17011162 be ng mounted on the pedestit1'6,fdoes not I move' with the tableA when the latter is shifted laterally. but remains on the pedestal, as shown in Fig. 2. .\nothcr roll 16?). (Figs. 1, 2 and T) is shown mounted on the pedestal 4 and this also supports the lower stretch or reach of the wire 1 but does not move with the table. being on a edestal. ()ther pedestals 166. N37. and 16s are shown (l ig, 1) and these pedestals are respectively provided with rolls 169. 170 and 171. also serving to support the under stretch or reach of the wire Ii.

Thus it will be seen that by the use of the tracks 18 and 19 and the.supplemental track supporting pedestals 24'. and by operating the motor 52 so as to rotate the main driving shaft 33, the table may be moved forwardly on to the tracks 19. as shown in Fig. r. the

entire table from one end to the other moving forward in this manner and 'arrying with it the breast roll 14, the table rolls 10 and the end roll 161). but not taking with it the dcckel strap 7 and associated parts, nor the couch rolls l5 and 16, which as previously explained are capable of independent adjustment to permit the movement of the table without their following. Before the table is thus advanced to its forward position, the deckel straps 7, with the deckel wheels 8 and 5), and the pond (it) are lifted bodily as previously explained so that they all clear the table and its wire, as shown in Fig. 2. Also the couch roll 16 is swung up and back and the other couch roll 15 lifted by cranes, as shown in Fig. 2. \Vhen the machine is arranged in this way the tracks are put in place, the table with all its attached parts run out on the front tracks as in Fig. 1, and a new wire is put its place.

To put the new wire in place, it is first slipped on the bottom couch in the usual way, and raised to." position 15, (Fig. 2). Pipes are shown in Fig. 2, as 175, 176, 177, 178, 179 and 180, all of these pipes being temporarily held in position at the sides of the pedestals 2, 3, 4, I), and (3, by means of holding devices such as shown in Figs. 11 and 12. Thoma comprise sad'ics 1H1 bolted to the various pedestals by bolts 182 and having seats 18% to receive the pipes, and pins 184 arranged to pass through side arms or projections 15%;) and attach to the saddles 181 by means of chain 1%. These pipes are placed over the lower reach or stretch of the new wire which iSStIllIig over the rolls 169, 170, 1th), 171 and 162, said rolls supporting the wire and said pipes holding it down, and also over pipes 188 and 189, supported by a rod 190 held in place by bracket 191 at the left hand end of the machine, as shown in Fig. The portion of the new wire between the pipe 188 and the couch roll 15 is supported by cranes or other lifts indicated diagrammatically at I extg'udmg longitudinally of the table and 192, 193, 194 and 195. When the new wire is thus suspended and arranged, as shown in Fig. 2, it is in condition to allow the table to be moved back in place. It is then lowered so that it will rest on the-table rolls 1, and will encircle the breast roll 14: and being al' ready extended around the couch roll 15. the, latter is lowered into its bearings which have lirst been properl adjusted for it and then the pipes 175, 176, etc., are removed. permitting the lower stretch of wire to rise. The table with the wire on it to this extent is then moved baclovardly by operating the motor 42 in a reverse direction. and more or less at the same time the couch roll 15 is lowered. thereby permitting the wire to come into its proper position with the slack taken up and the couch roll 15 adjusted back to its normal position and the couch roll' 16 lowered so as to apply tension to the upper stretch. The tightening device 135 is then lowered so as to apply tension to the lower stretch. The deckel straps T with their associated parts are then lowered into position and other adjustments made so that the table is back in its place carrying a new wire and the machine is all ready for operation \Vjtll that new wire. The tracks 18 and 111 are then removed and the operation is completed. and the machinev ready for further use.

' It will be understood that changes and modifications may be made without departing from the spirit of the invention.
