Application filed ianuary 10, 1918. Serial No. 211,138.

To all whom it may concemf Be it known that L-JAMEs K. DARBY, a

citizen of the United States, residing at Chillicothe, county of Ross, State of Ohio, have made a certain new and useful invention in Paper-Making Machines, of which the following is a specification.

This invention relates to paper making machines.

The object of the invention is to provide a paper making machine which is simple in structure, efficient in operation and economical of manufacture and maintenance.

Further object ofthe invention is to provide a paper making machine so constructed as to allow the ready renewal of the forming wire without removing any rolls from the machine.

A. further object of the invention is to provide a simple, quick, and easy wire re-' placing apparatus.

A further object of the invention is to provide a paper making machine so constructed as to allow the ready renewal of the forming wire without removing any rolls from the machine and to level, line and clean the rolls .while in their usual position.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown by the accompanying drawing and finally pointed out in the appended claims.

Referring to the drawing:

Fig. 12 is a detail view of an adjustable bearing arrangement employed in accordance with my invention.

The same part is designated by the same reference numeral wherever it occurs throughout the. several views.

Referring to Figs. 1 and 1, the combination of which shows a usual structure, of: fourdrinier machine, 1 designates the end less wire, 2 the bottom couch roll located in block 3 and held therein by pins 1 supported by the couch side housing 1*. 5 designates the top couch roll and 6 a guide roll. The latter is also supported by suitable bearings in the couch' side housing. Suction boxes 7 are provided with the suction box table rolls 8 and wire 1 passes thereover and beneath the dandy roll 9 and over table rolls 10. 11 designates the breast roll and 12 the carryin table, one of w ich, for example, as desig nated at 1%, may be a stretching roll to maintain the wire 1 taut. A water connection for the suction boxes 7 is shown at 13. The housing for the breast roll is shown at 14 and is provided with a boss 15 thereon for the purpose which will be hereinafter described. The housing 14: is provided with a screw 16 for adjusting the forming elevation of the .wire as is usual and well understood. -Reference character 17 designates the wheels for the truck end of the table, which operate on the supporting rail 18 therefor, which rail 18 .is provided with a notch or depression 19, inwhich the wheels 17 are normally suspended, relieving the wheels of-all' weight when the paper 'machine is in position for operation as'shown in' Figs. 1 and '1. Thesupporting rails 18 rolls disposed beneath the lldd on opposite sides of the machine extend from machine being designated 20 while the couch roll end of the table rails on opposite sides of the machine being designated 22. At the.

arrangement will be described hereinafter.

The table rails 22 at the couch end of the machine are supported by means of the cross beams 27 which in turn are supported by rails 18 and blocks 26 which are fastened 'to the rails 18 by locking devices 23, see

Figs. 1, 1, 2 and 4. A chain hoist 30, mounted on a suitable pulley 31 is provided at each end of the machine and supported by the frame work thereof for a purpose which will .be more fully hereinafter set forth. The foregoing briefly enumerates the various parts which go towards making up the fourdrinier machine of the usual con struction, the forming wire 1 being made usually of copper wire, woven in an endless belt passing around the various rolls, as the paper forms on the table of the machine. The wire 1 is so constructed for the urposes required that it is very easily bro en, and in fact can be destroyed with the tip of the finger. These wires are usually from 60" to 232 in width and travel as fast as 800' per minute. From this it is obvious to maintain the forming wire in operative condition, the same must be handled with extreme care to guard against possible destruction or injury, which necessitates winding a new wire on the apparatus, involvin littering up the machine and great waste 0 time, labor and expense. It is customary in stringing the wire 1 on the fourdrinier to remove all of the rolls of the machine wit-h the exceptionof the bottom couch roll, then lifting the front end of roll 2 by removing the supports therefrom, slip the wire 1, previously wound on long poles. for instance, as shown at 40, Fig. 8, over the roll 2, then stretch the wire back to the breast roll 11, and then replace all the rolls. suction boxes, and savealls by passing them through the wire 1. Should any mishap occur, the wire- 1 is damaged beyond use or, at the best, has a very short life on the machine, giving a great deal of trouble, and involving a great waste in defective paper, in the continuous operation of the machine and involving a vast expense as the wires now in use cost fromone hundred to a thousand dollars each. All this is in addition to the time required to replace the wire with an undamaged one, which in practice, takes from two to three hours, at the least, and as the be subsequently installed until the nick, dent or other defacing mar is removed from the roll. This may be more apparent when it is considered that practically all of the rolls and in fact the entire fourdrinier parts are constructed preferably of copper or brass.

It is among the special purposes of my present invention to provide means to string the endless Wire 1 Without taking the rolls from the frame of the machine, thereby eliminating any danger of the rolls being damaged by handling and in addition theretoto reduceto a minimum the possibility of injury to the wire itself and still further in addition thereto to reduce the length of time required for the replacing of a damaged or faulty wire, to a very short time and with a minimum amount of labor involved. As illustrative of the principle of the invention involved and referring to Figs. 1 and 1 the fourdrinier parts are in position as shown in these figures.

The fourdrinier proper may conveniently be divided into twolparts; the breast roll or truck end and the couch end. The former consists of the breast roll 11, breast roll bearings 56, Wheels 17, table rails 20, cross beams 21, connecting table rails 20, blocks 25 on top side of table rails 20, in line with cross beams 21 as shown, savealls 50, partitions 51, gate 5 stem 52, 53 and 54, troughs 111 and table rolls 10. i I

The couch end consists of the bottom couch roll 2, the removable block 3, taper pins 4, couch side housing 4?. guide roll 6, suction boxes 7, table rolls 8, water connections13, blocks 26, (in line, with the cross beams 27 and connecting table rails 22), jury post 55 (for temporarily supporting the table rails 22 at one end) and deckle pulleys 92 with suitable bearings 92. consisting of a journaled bearing having .an adjustable stanchion 192, which is threaded to receivilocknuts 193 for holding the stanchion in the table rail 22. Bolts 29 (Fig. 3) connect the table rails 22 to the housings 4", for holding this part of the housing in position and to preventtipping when the removable block 3 is displaced and the dandy roll 9 and stand removed for restringing the wire.

Rails 18 may conveniently extend from the couch housing l to the breast roll housing 14 and be locked thereto respectively by lock 27, above the rails 22 to'the rail 18, and are lock-bolted thereto at 23.

If it is now desired to restring the wire, lock-

bolts

21 and 23 are removed and the jury posts placed in the position shown in Figs, 1 and 1*, for the purpose of supporting the table rails 22 at one of the blocks 26. The chain hoist 30, operated by pulleys 31, now engages the rails 18 at both ends (as shown in Figs. 1 and 1 and takes the weight from the lockbolts 28. Lockbolts 28 are then removed at both ends of rails 18. The couch ends of the table rails are now supported by the couch housing 4*. The jury posts 55 support the other ends'of the rails and hold the couch end of the table in the position shown in Fig. 2. All the lockbolts having been removed, the rails 18 are supportedby the chain hoists 30, and rails 18, in turn, support the truck end by means of the cross beams 21.

- Previous mention has been made of notches or depressions 19 inthe rails 18,

in which the wheels 17 of the truck end are normally suspended. The rails 18 are lowered by means of the chain hoist 30, and the truck end, supported free on the rails 18, also lowers with the rails until the breast roll bearing 56 strikes the boss 15 fastened to the breastroll housing 14. This causes the truck end to slide forward on cross beam 21 along the rails 18, until the truck wheels 17, normally in the notches 19 of the rails 18, lift out of the notches'19 and in so doing take the weight from the truck end and of the cross beams 21, thereby causing the truck end to be supported on the wheels 17. The deckle pulley 92 and stanchion hearing 92 are now taken from .their normal position, as shown

inFigures

1 and 1*, and placed on the auxiliary bearing 93, situated on the ruler bar 90 of the deckle frame.

The truck end ofthe machine now rides on the wheels 17 and is lowered a sufficient distance, by hoists 30, to enable the truck end to be passed forward under the couch end to the position shown in Fig. 2. With the truck end lowered, and shoved forward under the couch end, the machine is doubled up so that the blocks 25 on top of rail 20 rest-on the bottom of the rail 22, spacing .the rails-2O and 22 apart, so thatin lifting the frames and rolls together no pressure will bear on any of the rolls.

By thus telescoping the fourdrinienas described above, I have reduced the extreme normal distance between the couch roll 2 and s the breast roll 11, about one-half. thus giving me a better working clearance in stringing the wire; also giving a better advantage for lifting the frame as the slack wire is slipped over the face of the rolls.

Furthermore, owing to the increased weight of the wire used on wide, high speed modern paper machines, I' provide special means for carrying said wire across the face of the machine rolls, and also-for removing the same from the shipping crate, and I will now describe this special means. By this means I am enabled to place the wire over all the rolls of the paper machine without removing the rolls from the frame, and this special means will hereinafter be known as the wire truck. This wire truck (see Figs. 6, 7 and 8) consists of a main frame 60, integrally-supporting a beam 61. This beam supports a couch lift 62, a breast roll lift 63,

spreader pipes

64 and 65, dolly truck 66,

post bearing 67, socket stand 69 (for'said.

post bearing 67) and journaled plates 72 which are provided with screws for the purpose of securing the plates to the two poles 40, and-on whichpoles the wire is wound. The journal plates 72 are supported by bearings on the dolly truck and post bearing 67. The post bearing is secured in the socket stand 69 on the beam 61 and the dolly truck rides on the beam 61 of the truck 60. A second truck 80 (see Fig. 2) is equipped with a socket bearing and is supported on the central cross beam 27 This truck receives the post bearing 67 on being removed from the socket stand 69. Therefore, in passing the wire over the face of the rolls the dolly truck 66, post bearing 67 and truck 80 (supporting the journaled plates 72 secured to to the place'where the forked end 68, ofbeam 61, on truck 60, meshes into the cross beam 21 at 21 of the truck end. The wire truck 60 being now positioned in line with the centre sections of the cross beams and blocks, supports the table rolls, suction boxes, rails,

crossbeams and blocks on the front side while the wire is carried across the face of the rolls. The couch lift 62 is then taken from the wire truck 60 and carried in line with the couch roll 2 and being hollow is slipped oyer the journal of couch roll 2 for an extension lift. The wire now unwinds from the wire-spoolas the-couch lift 62 is carried to the couch roll journal. The breast lift 63 is now removed from'the wire truck 60, and carried in line with the breast roll journal 11, the same being hollow is also slipped over the said roll journal as an auxiliary extension lift.

On referring to the drawings, Figs. 1, 1

and 2, it will be noted that the box bearings lifting the said rolls any housings at the said box bearing also lifts with the

rolls

2 and 11. It will be understood that when the auxiliary supports at the couch 62, breast 63, and truck are in place, that as the front side of the frames and rolls are lifted at the same time, the auxiliary lifts brace each other by the three point suspension At this-stage breast roll 11 is in the desired position, therefore the breast auxiliary lift 63, by placing a post (not shown) under the outer end of saidlift, sustains roll 11 and any connections. As the truck beam'61 has been meshed at the forked end 68, into the cross beam 21 of the truck end at the central cross beam 21 and as that part of the frame between the breast roll 11 and couch housing 4 is also at the proper elevation, the truck beam 61, supported on the truck wheels-.60, sustains the frame as an auxiliary lift. By this means it will be understood that the breast auxiliary lift 63,

and the truck auxiliary lift 61, hold their part of the load suspended, as the rail 18,

supported by the chain hoist 30, which has been carrying the load, is lowered to. the foundation plates, the chain of the hoist 30 .is taken out of the way.

It Will be understood that to place the wire across the face of the rolls a clear passage of the frame is necessary and for this purpose the removable block 3 and attached parts are removed. The spreader pipe 64 is now carried to the breast end of the wire loop, and spreader pipe is taken to the couch end. The 'ury post 55 is now taken out of the way, the wire spool on the beam 61 is now ready to car the wire across the machine by the following method.

As the truck-beam 61 engages the cross beam 21 at 21", the cross beam 27 at 27 is also in line with the truck beam 61, the wire spool is supported ,on the truck beam 61, by means of the dolly truck 66, and post hearing 67 in the socket stand 69. Post bearing 67 is now removed from the socket stand 69 and placed in the socket of truck 80 (Fig. 2). The wire spoolis now riding on the two

trucks

66 and 80, on the truck beam 61, and cross beam 27. The spreader pipes 65 at' the couch end of the wire 10?, the spreader pipes 64 at the breast en of-the wire loop now spreads the wire so that it will not foul the ends of the rolls or the frame. The wire spool is now pushed across the machine riding on trucks 66 and80, and as the wire spool is moved-'acrom the machine to the desired position, the

spreader pipes

64 and 65 are carried across with the wire looped at their respective ends.

To one skilled in the art, it is apparent that the wire truck arrangement is flexible and that as the poles are frequently longer than the wire and project beyond the edges and thereof, my wire truck is suitable for large or small machines. This has never been done before and is a great advantage as well as saving of considerable expense where different sizes of machines have to be rewired.

To reassemble the machine after the wire is thus put in place, the block 3 under the roll-2 is re laced and fastened in position by means of the pins 4; the chain hoist 30 is again fastened to the rails 18, the jury post 55 is again swung into place, the rails 18 are raised by means of the hoist 30. so as to take the weight of the truck end, the wire truck 60, breast lift 63, and couch lift 62 are then removed and again the machine 1 is in the position and condition with respect to the various elements, as shown in Fig. 2*;eady to be extended to its proper position by a reversal of the operation hereinbefore described, which roper position is shown by the combined Figures 1 and 1 The spread pipes 641-, 65, being pressed through the wire 1 are then taken out of the way.

In stringing the wire 1 at the presenttime great care must be taken thatthe wire. is not damaged in any way, and also that the wire must be strung true and in line so that during' the operation of the machine, the same will travel in a perfectly straight line, thus preventing excess of Wearing on the edges of the wire. 1

The wire being .slipped over the rolls, as shown in Fig. 2, by the slack irregular line 1,- the wire spool, supported by

trucks

80 and 66, is then in ositlon to unwind as the truck end is care ully moved back to the position shown b the combined Figs. '1 and 1. Thereupon t e wire 1 on the spool unwinds until all of the wire 1 is ofi" of the wire poles 40, one of the poles 40 being on theinside of wire 1, is passed through, and both poles 40 being. now empt areremoved with the

trucks

66 and 80. "T e; wire i'now has more or-less slack and it isga't" this point that I provide means for insuring that the wire is put on straight and in true alignment. To insure the wire 1 being put on straight so as to run in. .agtrue line theshowin a true line for the edge of thewire 1 to f0 low as the trucliend is movedback to its proper position, thus insuring a proper alignment of the wire on the rolls.

-I also provide a means to keep all of the rolls in proper alignment and level while the paper making machine is in operation. Even when the paper making machine is in operation, it can be accurately determinedv what rolls are in alignment. In the present form of fourdrlnler machmes, it is necessary and customary to remove all of the rolls from the machine except the couch roll 2' and breast roll 11 in placing the rolls in alignment, and should a roll get out of alignment, it often spoils the Wire and several wires which are successively employed thereon until the rolls are re-aligned in their proper position. In my present machine after the couch roll 2 and breast roll 11 are placed in a proper position aboss bb is fastened permanently to the foundation plates on the front and back sides and so located thereon that a plumbbob line dropped fromfthe face of the couch roll 2 and the breast roll 11 coincides therewith, so that it is easyto determine whether or not the couch roll 2 and the breast roll 11 are in accurate position. This arrangement has anumber of advantages over the present customary method which consists infirst lining the couch roll 2 and then line the breast roll 11 with roll 2 by passing a line around both

rolls

2 and 11, as the present method requires considerable skill. I also place on the foundation plates additional bosses 7)?) beneath rolls 12. The journals being accessible I strike a line through the center of the journals. The table rolls 8 and 10 supported on the table rail 20 have extended journals so that the bearings are supported on the table rail 20 which is slotted to allow for adjustment to right or left as shown at S. (entral with the slots are marks indicated at T placed on the rail 20 central to the extending journals of the rolls h and 10. The caliper feeler F placed on the rail 20- at the marks T is moved under the extending journals of the rolls 8 and 10. and proves that the rolls 8 and 10 are in line and level as will be readily understood. Should the caliper feeler F prove that an roll 8 or 10 is out of l ne or level on the rail 20. the operator loosens the lock nuts that hold the bearings of the rolls 8 or 10 to the rail 20. moves the roll to the proper line or level and again locks the hearings to the rail. At the present time, it is customary to place the stem of the bearings of the rolls 8 and 10 into a hole drilled into rails 20 allowing no adjustment to the right or left. but merelya vertical adjustment by means of a set screw and lock nut fastened under the rail 20 which parts, being the present well known parts of a fourdrinier machine. are not shown. As the bearings wear. they are adjusted vertically. as desired. but as the stem of the bearings often fit loosely in the rails 20 the bearings wobble the rolls 8 and 10 run out of line,

" crowd at the shoulders of the journals, the

journals become sprung. thereby caus ng the rolls to wobble in their bearings and jump. causing marks or a weak spot in the paper. which causes the paper to break. Often the rolls 9 oi. 1O atop turning, which causes the Wire 1 to wear a. flat side on the rolls so that if the rolls start to turn again in this condition they mark the paper and wear ridges in the wire 1, causing the wire to have a very short life. To overcome this recognized objection to the present type of fourdrinier machines, I place a hollow tube 35, see Fig. 12, threaded on the outside and flattened on two sides 38 to slide in the slots S, of

rails

20 and 22. Placed on the hollow tube 35 are two

lock nuts

36, 37, locking the tube 35 securely to the

rails

20 and 22. At 34 is shown a bearing of table rolls 8 and 10 which sets into the hollow tube and is the same as the bearings now in use. By this arrangement no matter how high the bearing 34 is required to be raised the hollow tube 35 is locked securely to

rails

20 and 22 and cannot wobble.

Also by means of the small motor M on the rail 18 (see Fig. 5) means are provided for turning the rolls by power. My reasons for this arrangement are as follows. In paper making operation, certain chemicals acting with the water employed cause the rolls to corrode, and if there is any scale or corrosion on the face of the rolls it has a tendency to cause the wire to become defective. It is the present method to use acids. or before replacing a wire to scrape the corroding scale off of the roll. I propose, before replacing a wire, to attach a small motor to the end of any of the journals and sand paper the rolls off by power, without taking the rolls out of the frame of the machin is removed when the machine is in operation.

At the breast end above the fourdrinier table is located the deckle frame consisting of the ruler bar 90, supporting side posts 91. deckle pulleys 94. breast board 95, head box 96. slices 97, adjustable supports 98, brass plates 99. and the wire slicer 100, auxiliary bearing 93 and pulleys 92.

Referring to Figs. 1 and 1, it will be noticed that the posts 91 are made adjustable. so that the posts .can beadjusted to any desired length. The smallest end of the posts 91 slide in and out. .Fastened to the upper part of the post 91 is an angle plate 101. The purpose of thisangle plate is threefold. First, in lowering the breast end of the machine. when about to put on a wire, the deckle frame will also lower, but I provide an angle plate 101 fastened to the upper section of the adjustable post 91 so that in Lowering the table rails 20 the deckle frame also lowers until the angle plate 101 rests on the shoulder of the lower section of the adjustable post 91, where the deckle frame rests while telescoping the table frame as hereinbefore described. The boss or angle plate 101 tests on therail 18 should the machine be of the shakeless deckle type. While the angle plate is not It is understood that the motor tween the housing 14 and the head. box 96 h fastened to the rail 18, the railgby means of the angle plate at all times supports the deckle frame when the machine isin operation, whether or not the deckle frame is vibrated. As the rails 18 support rails 20 and 22 any change in elevation of rails 18 changes rails 20 and 22, and changes the elevation of the deckle frame as Well. The

rails

20 and 22 support the table rolls 8 and 10. The rolls 8 and 10 with the wire 1 comprise the formin paper flows. The sicers 100 attached to the deckle frame therefore adjust themselves with the

rails

20, 22 and 18.

The deckle frame, breast board 95, head box 96, are all coupled together. The breast board 95 rests lightly on the housing 14 and is supported by the adjustable post 98 with the

screws

102 and 16 coupled together, to afford adjustment of elevation of the breast end of the machine. The adjustable arrangement consists of the breast housing screw 16, head box screw 102 connected by the shaft 103, supported by brackets 104 and 105. At the breast. housing end of the shaft 103, the gears 106 engage the screw- 16. At'the head box end of the shaft 103 the gears 107 engage the screw 102. The

shaft 103 is operated, as shown, by the hand wheel 108.' The

screws

16 and 102 being of the same pitch, and the gears 106, 107, being of the same ratio, the adjustment beis exact. The deckle frame and head box are independent of the vibrating motion of the fourdrinier table, and the adjustable posts 98, relieving the weight of the head ox 96, takes the weight ofi of the housing 14 as will be readily understood.

The fourdrinier parts at the breast end of the-machine, suitable arrangement being shown at 115. As shown in the drawing (Fig. 3) the shaker 115 is attached to the breast hous-' ing 14, and as the breast housing 14 supports the rails 18, by means of the lockolt.28, the rails 18 also vibrate with the breast housing 14, and as the rails18 support the

rails

20 and 22, of the wire formmg table, the vibrating motion is conveyed to the wire forming by the rails 18. Therefore, both the

rails

18, 20 and 22 vibrate ment.

Previous mention has been made to the angle plate 101 fastened to the' posts 91 of the deckle frame, and as the posts 91 are telescopic, the angle plate 101 extends over on the rails 18, and when the machine is in a normal running position these angle plates fastened to the upper part of the tele- SCOplC by bearing on the rails 18. rails 18 adjust the elevation frame, by means of the ppper Therefore the of the deckle. section: of the table over which the tight box, see Fig.

vibrate from side to side, a'

table rails 20 and 22 by the shaker arrangepost 91, supports the deckle frame tlescdpic posts 91, supported by the angle plates 101, bearing on the rails 18. Thls 1s of vitalimportance owing to the fact that the slicers '100, which are at times but oneeighth of an inch from the wire, when the machine is in operation, must be ad usted with the forming wire whenever the running elevation of' the wire is changed.

When the deckle frame does not vibrate, the lower section of the telescopic posts 91 are fastened to the floor bybolts 91, wh1le the angle plates 101 bear on the ralls 18, permitting the rails 18to slide to and fro free beneath the angle plates 101.

If it is now desired to vibrate the deckle frame, the telescopic posts 91-are released at the floor by removing the bolts 91*. A breast board bracket 95 heretofore bearing lightly on the housing 14 is bolted to the housing 14 at 95*. The head-box 96, secured to the adjustable post'98, is released from the posts 98 by removing the bolts 96. back and forth on posts 98 as the entire machine vibrates. It will be understood that the elevations of the forming wire, the deckle frame and the head box 96, is at all times regulated by the two elevation screws This permits the head box to slide Reference has been made to the savealls 50 with partitions 51 located beneath the table rolls 10 into which the waterused in forming papers filters through the wire 1.

The savea-lls 50 consist of a shallow water- 4, the bottom resting on beam 21 and the sides extending to the same elevation as the forming table, making it possible'to submerge the rolls 10 completely. Extending across the savealls 50 are the partitions 51 dividing .the savealls into three sections, each section having a. trough "111 fastened permanently to the saveall 50. The saveall system forms a part of the truck end of the fourdrinier and isnot removed from the fourdrinier at any time, but if it should be desired to wash out the savealls before putting on a wire, by removing one or more of the table rolls 8 from their beerings and laying the roll or rolls over on top of the accompanying rolls, enough room will be madeto clean the savealls and the troughs as desired.

As shown in the drawings, the savealls system vibrates with the fourdrinier table and as the sides of the savealls 50 are at the same elevation as the Wire. the partitions 51 being lower than the forming wire. enough clearance allowed so that the wire. 1 will not be damaged in any way by the partitions, By regulating the How of Water into the sa-vealls and, then into the trough 111,

the savealls 50 by closing the flow into the trough 111, and as the water cannot escape through the wire 1 into sa-vealls 50, the

water passes over the partitions 51, forming in free or slowstock, the word free.

meaning that the water escapes from the stock easily, and the word slow that it does not escape easily. A; better understanding of the method of regulating the water within the savealls 5 0 can be had with. reference to Figfi wherein thepartitions 51 divide the saveall 50 into three sections. In this view, 52 are the gates, 53 the openings in the gates, 54 the openings in the bottom of the savealls 50, 111 the trough fastened to 50 directly under .the openings 54. Referring to Fig. 9 it will be noted that at one section the gate 52 is in such a position as to close all of the openings 54 so that no filter water can flow into the trough 111. At the next section, the gate 52 is positioned to permit the filter water to pass through the partially opened gates 53, through 54, into the trough 111. The next section has the gate 52 wide openso that all filtered water may pass through the openings 53 through 5 into trough 111 then into the vent trough 110.

The advantages of this arrangement embodying my invention are obvious, principal among which being the, control at will of the use of any desired fibre allowing the use of various fine grades of paper. In regulating the filter-through thewire 1 by flooding the savealls and by flooding that section of the savealls next to the breast roll 11 first and by passing the water over the partitions 51 from onesection to the other until the last section from the breast roll 11 is reached, then by letting all the water filtering through the wire 1 escape through the one trough 111 by closing the other troughs, the rush of excess last section 50 into the trough 111 has a tendency. to form a siphon and cause a forced suction on the filtered Water in turn causing the filtered water to pass through the wire 1 by a force greater than gravity and therefore causing the fibre forming on the wire 1' to give up more water than under-natural tendencies. This, of course, causes the fibre to be drier and stronger than otherwise.

The guide roll 6 may be adjusted by the usual automatic arrangement which is not shown in the drawing. Whether or not the guide roll is automatically adjusted the same has always been a source of considerable trouble and I have traced the trouble filtered water through the' not to the automatic arrangement, which is generally employed for maintaining the same n alignment, but to the bearings of the guide roll itself. Assuming that the true normal position of the guide roll 6 should I be at a true right angleto the line of travel of the wire 1, it must be remembered that the fourdrinier machines consist of at least 20 rolls any one of which may get out of line or level and thus the guide rolls 6 by means of the automatic arrangement located to operate out of line to compensate for any other part of the machine, which through any cause, becomes out of line.

It is a well known fact in practice that when a roll is out of line or alignment, the roll will crowd against one of the bearings, causing the same to become defective and to give considerable trouble." In practice, I

have found that when the guide roll is working out of line (and as a general rule it is always out of line) it will crowd against the bearing on one end, and should the same crowd the front side of the fourdrinier, on which side the automatic arrangement with the carriage is positioned, as is well known in the art, the roll jams the carriage so as to cause the automatic arrangement to work in a defective manner. Should the guide roll jam against the bearing on the end opposite the automaticfa-rrangement and carriage, the roll compensates in the usual mannerior the disalignment at some other part in the machine, in the usual and intended manner. To overcome this difficulty, I have caused the journal on the guide roll 6 on the'end opposite to the automatic arrangement. and carriage to be set in a grooved bearing, or to extend the journal beyond the bearing on. the opposite side of'the automatic arrangement and carriage a'ndplace a safety collar on the said extended journal in such a way as to prevent the guide roll crowding against the front side as will be readily understood by reference to Figs. 10 and 11.

In Fig. 10 is shown the bearing of guide roll 6, wherein 45 is the journal of the type now in use at both ends of the roll. 46 designates the journal to run in the grooved bearing so that should the guide roll 6 be out of alignment, the shoulder of the bearing 45 cannot jam against the front side of the bearing.

Fig. 11 shows the guide roll 6. front side journal 4;? back side journal at 48 extended, 49, safety collar 49, fastened securely to journal 48, causing the guide roll 6 to act in the same manner as described above in connection with Fig. 10.
