Application December 23, 1929 Serial No. 416,024

'12 Claims. (01. 92-44)- vide for laterally removing the table structure of the machine. This lateral removal has. however, heretofore, always been in a direction at right angles to the longitudinal dimension of the machine, and additional provisions have been necessary for reducing the distance between the couch and breast rolls to provide slack between these parts for the application of the wire loop.

It has been proposed to obtain this slack by swinging the couch roll back in a vertical plane toward the breast roll end of the machine on horizontal pivots one at each end of the couch roll, but this is objectionable, particularly in the construction 0! the large, fast and heavy machines of today.

Subsequent proposals have been made for moving one part relative to the other part in a direction longitudinally of the machine to obtain slack, but these have required an independent and entirely separate longitudinal movement between the parts in addition to the lateral movement of the Fourdrinier table at right angles to the longitudinal dimension of the machine. The previous proposals for obtaining the relative longitudinal movement have resided in lifting the couch roll and shifting it longitudinally toward the breast roll end of the machine by crane means or in telescoping the parts longitudinally as by moving the couch roll longitudinally onto the Fourdrinier table or by telescoping the breast end of the machine toward the couch and, the telescoped parts being withdrawn laterally at right angles for replacing the wire. It has also been proposed to telescope the parts longitudinally without any lateral removal, the forming wire being slipped over the longitudinally telescoped parts without removing any of said parts laterally from operative position. The lifting and longitudinal shifting of the couch roll has objections, and the telescoping of the parts introduces further and important objections by breaking and weakening the frame structureof the machine. There are other objections, such as the requirement of entirely new and particular types of frame structures which have prohibited embodying these previous wire changing proposals in many existing machines which are otherwise sumciently satisfactory and which represent large investments.

There have been other wire changing proposals, such as supporting the Fourdrinier table by overhanging stands with permanent supports at one side of the machine only to enable passing the wire loop over the overhanging ends and around the table, the couch roll being raised at its outer end so that the wire loop may be slipped thereover. It has also been proposed to hinge the entire table frame along one side to enable its opposite side to be lifted vertically for application of the wire. These methods are all unsuited in the large, fast and heavy present day machines and in these last referred to methods, as in the others, any shortening movement between the breast and, couch ends has been a shortening movement only and in nowise obtained by the movement which laterally removes and replaces the Fourdrinier table. The prior art provisions for reducing the distance around the breast and couch ends of the machine have, aside from whether there has been any lateral re=- moval of the table structure or not, been different from and without the advantages of the present invention.

The object of the present invention is the provision of a generally improved ,and simplified relative movement between the parts of the machine.

Another object is the provision of a new relative movement for removing and replacing the Fourdrinier table or any other desired part or combination of parts and for shortening the distance between the couch and breast rolls to pro vide the necessary slack .therebetween and a movement which may be of a simple nature as distinguished from the compound or plural movements and accompanying provisions heretofore required.

Another object is to eliminate the necessity of telescoping one part longitudinally relative to the other part, as well as the accompanying breaking and weakening of the frame structure.

Another object is to eliminate the necessity of swinging of both ends of the couch roll on horizontal pivots and the accompanying objections thereto.

In my copending application Serial No. 307,- 966, filed September 24, 1928, and in the copending divisional application Serial No. 431,734, filed Feb. 27, 1930, which is a division of application Serial No. 307,966, I'have provided what maybe ing from the inner portion into the adjacent aisle.

The outer main cross rail parts may be formed integrally with the inner parts, or they may be formed separately and permanently or temporarily extended out into the aisle. The main crossrails sustain and guide the laterally movable part of the machine and may be as heavy'as desired. These parts need not be removed to permit the application of a wire, as previously necessary, but may be left permanently in place. They are provided with pad raiis which are preferably relatively rigid and may be lightweight and relatively thin because they do not sustain or guide the laterally movable part of the machine.

In chaging or applying a wire, the lower or return run of the wire is arranged over the- 'main cross rails whereupon only the lightweight andv relatively thin pad rails are laid within the wire loop over the top of the lower or return run of the wire and upon the main cross rails. The

wire, while relatively fragile and otherwise easily injured, has great strength and resistance to injury in .compression and, with the bottom run of the wire disposed between the main cross rail and the "light pad rail, I have found that themachine may be moved over the pad rails without injuring the wire, notwithstanding the sustaining of the machine by the cross rails through the wire itself and the upper padrails.

The paid rail provisions of the applications above referred to are, so far as I am aware, broadly new and not limited to use with the new relative. movement between the parts provided by the present application, and this invention is also, so far as I am aware, broadly new and not limited to use with said pad rails. The present invention has, however, provided for combining the new relative movement between the parts with the new paid rail provisions above referred to. This combination has many advantages and is important in the more'limited aspects of the present invention, and the appended claims arev directed not only to the new relativemovement between the parts, per se, but to the combination of this new relative movement with the pad rail provisions above referred to.

In order to acquaint those skilled in the art with the manner of constructing and operating the present invention, -I shall now describe, in connection with the accompanying drawings, a number of specific embodiments of the invention. i

The particular forms of the invention illustrated in thedrawings are not to be taken'as' limiting it, but are intended to be illustrative of various manners of embodying and carrying it out. The present invention may be embodied in the original construction of the machine, or it may be embodied in existing machines in many instances without changing the operation or construction principles of the machine and, in many instances, the present invention may be embodiedin existing machines in which it has heretofore been impossible to make'provision for quick and convenient changing of the wire.

The particular structural details, as-well as the particular relationship and combination of the parts, may vary widely, and I have, therefore, illustrated these details diagrammatically and only suiilciently to enable those skilled in the art to understand and practice the invention and some of the variations contemplated within the scope of the broaderaspects thereof.

Referring first to Figs. 1 to '7, inclusive, the removable table structure is designated inv its entirety at 5 and includesside truss rails 6 and side frames '7. The breast roll housing comprises a removable part 8 suitably carried by the table 5 and a stationary breast rollhousing part 9 having fixed or stationary support. Longitudinally extending shaking table rails 10, with vertical tie members 11 between them and the truss rails 6, form, a truss shaking end supported at 12 on the breast roll housing part 8 at the breast in a generally horizontal plane.

end and at 13 on the side frames 7. This truss bridge extending from the breast roll housing part 8 to the side frames 7 is preferably provided with suitable shaker means, shown, illustratively, at 14, and provided with means indicated at 16 and 1'? for transmitting the shaking action to the shaking part of the table.

' Extending from 18 to 19 are relatively short dead table rails 20. A guide roll is indicated at 21 and a suitable couch roll is indicated at 22. The couch roll 22 is preferably of the suction couch type and is illustrated in this particular embodiment as a cantilevered suction =couch driven from a drive shaft 23 through a spur gear 24 and a meshing gear 25.

The roll 22 shown is of the cantilever type but it is to be understood that this roll may be of the non-cantilever type. Beneath the outer end of the roll 22 cantilever or non-cantilever is a removable block 26. Where the couch roll is of the non-cantilever type porter means 27 (Figure '7) is adapted to be slipped loosely into the end of the suction box through the open end of the roll 22 and connectible to a chain fall or other suitable means 28 for releasing the outer end of the couch roll 22 from the block 26 sumciently to permit removal and replacement of said block as well known to the art.

In Figures 2 and 3 a stretch roll is shown at 29, by adjustment of which tension may be placed upon the forming wire 30 to stretch it as desired. Wire rolls along the lower or bottom run of the wire are indicated at 31, 31a, 31b, 31c, 31d, and 31c, and at 32 are cross braces tying the front and back side frames together.

The rails have swivel joints at 12 and universal joints at 13, which joints permit oscillation The universal joints at 13 may also permit the breast end of the removable table structure to be raised or lowered as desired.

In Figures 2 and 3, the machine is not shown as vertically adjustable, but provision for vertical adjustment may be made as in the succeeding embodiments. The breast roll indicated at 36 is suitably carried by the removable breast roll housing part8, and when the table structure is in its normal operative position as shown in Figure 2, and diagrammatically in full lines in Figure 1,

the breast roll housing part 8 rests upon the stationary housing part 9 and is supported at the breast end of the machine thereby.

The usual table rolls are indicated at 40 in Figures 2 and 3, and the usual or suitable suction boxes are indicated at 41.

The wire is in the form of a continuous loop well known in the art and travels in the direction indicated by the arrow A in Fig. 2 around the breast roll 36, over the table rolls and guide roll 21 around the couch roll 22 with the bottom or return run of the wire travelling beneath the 'stretch roll 29, up over the roll 31 and around the breast roll 36. At 42 is the usual head box I table where the table is adjustable vertically, as

will appear in connection with the succeeding embodiments of the invention.

Any suitable or preferred deckle means may be employed in connection with machines embodying the present invention, and such deckle means being well known in the art and forming no part of the present invention, has been omitted from the present disclosure. It is also to be under stood that the machine of Figs. 1, 2 and 3 may be provided with save-alls or any other parts.

The new relative movement for removing the 7 table or other part of the machine from and replacing it into its normal operative position, and for shortening the distance between the couch and breast rolls, comprises, broadly, a diagonal or intersecting movement of one part relative to another. This provides for transporting a desired part into the aisle and for obtaining the desired shortening of the distance between the couch and breast rolls and the accompanying slack without telescoping one part longitudinally relative to another part, as well as without breaking or weakening the frame structure and without swinging both ends of the couch roll on horizontal pivots toward the breast roll. So far as I am aware, this provision is broadly new whether both parts or only one part is moved, so long as there is a diagonal or intersecting movement of one part relative either to the extension or direction of movement of the other part. One part may be relatively fixed, except for theusual or any suitable provision for passing the wire loop thereover, and the other part may be removed outwardly and diagonally toward an extension of the relatively fixed part. or both parts may be removable out into the aisle, one laterally at right angles to the longitudinal dimension of the machine, and the other with a diagonal'or intersecting movement, or. obviously, both parts may be removed with a differential diagonal or intersecting movement between them, either both toward the same end with a diagonal differential between them, or each diagonally toward lateral extensions from the opposite ends of the machine as normally positioned. That is one part may be removed in a direction diagonally toward one end and the other removed in a direction diagonally toward the opposite end or both parts might even be removed in directions diagonally toward the same end but at different angles so that the distance around the parts will be decreased with removal and returned to normal in replacement of the parts. It is therefore intended that the appended claims be construed accord-- ingly. 1

Within the present invention, the diagonal or intersecting movement may be in either of the parts the distance between which it is desired toshorten. It is also contemplated within the present invention that the part, or parts, within the wire loop may be removed sufficiently to permit stringing the wire in the position normally occupied by the machine and the removed part or parts may be then moved back into the wire loop or the wire may be strung in an aisle adjacent the machine and the part or parts which are removed may be moved into the loop in their removal from normal operative position. Of course,the removable part or parts of the machine may be removed from operative position and the wire slipped over these parts in their removed position, particularly where there is ample available space.

To permit the placing of a wire on the machine of Figs. 1 to '7, the table 5 is arranged to be run out bodily in a diagonal direction into the aislealong the .front of themaehine on tracks 50 arranged diagonally across the usual beams or main sills 51, for example. Obviously the removal may be into the aisle along the rear side of the machine or provision may be made for removal into ither side aisle. The main longitudinal sills 51 may be rigidly supported upon the floor or main foundation structure of the machine, and diagonal extension tracks or rails 52 are extended out into the aisle preferably as continuations of the tracks 50, although this may vary, as will hereinafter appear. In Fig. 1 I have shown one more extension track 52 at the lefthand end than there are tracks 50 to sustain and guide the end of the front of the machine which projects to the left of the front of the first track 50 due to the diagonal disposition of the tracks. The extension tracks 52 may be formed integral with the tracks 50, as shown in Figs. 4 and 5, or they may be made up in separate sections '50 (Fig. 6) arranged diagonally across the main 'sills 51 with extension rails 52' arranged in alignment with and as continuations of the rail or track sections 50', the inner ends of the extension rails 52' being adapted to be supported upon the outer main sill 51, or otherwise as desired, and their outer ends being provided with suitable supporting means 53, which may be in the form of an additionai longitudinal sill or in the form of sep- "arate or inany other suitable supports such as the floor or foundation for the machine.

The rails 50 and the integral extensions 52 in Figs. 4 and 5 may be permanently bolted to the main sill's or other supporting means 51, or otherwise permanently embodied in the plant structure. This permanent disposition of the rails 50, 52 is permitted by the pad-rail construction of these rails, as will hereinafter appear and which is predicated upon my co-pending application Serial No. 307,966, filed September 24, 1928, and the co-pending division of that application, Serial No. 431,734, filed Feb. 2'7, 1930. Where the aisle or extension rail sections 52 are made up separately, as in Fig. 6, these extension sections may be removed out of the way after placing a new wire on the machine, the inner rail sections 50' of Fig. 6 being again adapted to be permanently bolted or secured in place at all times in the manher of the integral diagonal rails 50-52 of Figs. 4 and 5.

The table 5 is supported by rollers 55 suitably secured along the front and back of the table as beneath the table truss rails 6 and side frames 7 on suitable brackets 56 formed integral with or rigidly secured thereto. The weight of the machine preferably normally rests' upon the main sills and cam or other suitable means is preferably provided for lowering the wheels or rollers 55 into cooperation with the tracks, lifting the machine from its normal support upon the main sills and transferringthe weight or support of the machine to the rollers 55 and their cooperation with the track rails for movement out of and into operative position.

Suitable means for this purpose will be described later, but it is understood that this means may vary widely, or may even be omitted within the scope of the'present invention. The rollers 55 are preferably flanged, or otherwise formed, to remain in proper cooperation with the tracks, and their axes of rotation, while not at right angles to the sills 51, are preferably parallel to eachother and one more ro1ler 55 is shown at the lefthand end of the front of the machine than at the'back for cooperation with the additional extension rail 52 at the lefthand .end. The

- diagonal disposition of the tracks and the disposition'of the rollers for cooperation therewith results in a staggered disposition of the rollers,

front and rear, although, of course, the angle ofthe tracks may be such, or the tracks may table in lateral alignment with the rollers coop-j erating with other tracks at the opposite side of the table.

It will now be apparent that, as the table 5 is moved outwardly from normal operative position, the supporting wheels 55 tracking upon the rails 50, 52 will cause the table to move outwardly diagonally or at an angle in a direction toward an outward extension of the couch roll 22, thereby not only. removing the table from its normal operative position, but at the same time, and with the same movement, shortening the distance between the breast roll and an outward extension of the couch roll.

I'his provides the necessary slack or clearance for applying the forming wire or for introducing the parts of the machine which must be disposed Within the wire loop.

Obviously. when the track rails 50, 52 are made up in separate sections, as in Fig. 6, the outer sections need not be in line with the inner sec tions, but the offset track rail arrangement of Figs. 8 and 11 may be employed in. lieu of the straight track rail arrangement ofFig. 1.

Any suitable or preferred means may be employed for rolling the table of Figs. 1 to 6 outwardly and inwardly upon the tracks 50, 52 or 50', 52'. Where the machine will permit, this table might be moved manually. The particular means shown in Figs. 1, 4, 5 and 6 is illustrative of any suitable means for this purpose. It comprises a jack shaft 62 supported in bearings 66 and driven by a worm gear 67 fixed thereon and meshing with a worm 68 fixed upon a shaft 69 which is in turn driven through a pair of meshing gears from the shaft '70 of the shaker means 14. The shaft 62 has grooved winding sheave pulleys 71 keyed thereon, and these pulleys are provided with suitable cables or equivalent flexible lines 72. The adjacent side of the table 5 is provided with hooks 73, one for eachof the cables, the ends of whichmay have eye bolts '14 for engagement with these hooks 73. Secured at the opposite side, as, for example, to the outer side of the opposite main sill 51, are suitable grooved pulleys 75 best shown in Figure 6.

Now assuming that the table 5 is in position over the main sills 51, all that is necessary to remove the same diagonally outwardly upon the track rails 50, 52, or 50', 52', is to pass the free 2 ends of the cables '72 over to and around the pulleys.75 and back to the opposite side of the machine where the eyes '74 are engaged with the hooks 73. Then, by starting the shaft 62 as by engagement of a suitable clutch 77, the rotation of the shaft will wind the cables 72 upon the sheaves 71, moving the table diagonally outwardly into the aisle tothe position shown in dotted lines in Figure 1 and diagrammatically in full lines in Figure 3. When it is desired to return the table to its normal operative position, the eyes 74 are disengaged from the hooks 73, withdrawn or removed from cooperation with the pulleys 75 and reengaged directly with the hooks 73, whereupon the shaft 62 is again started and the pull of the cables as they are wound upon the sheaves 71 is imparted directly to the adjacent side of the removable table, drawing or pulling the table over the. tracks 50, 52 back into normal operative not in anywise limited to any particular manner 0 of moving the table into and out of operative position, and the preceding description of the particular power means shown for this purpose is illustrative of any suitable means, power or manual, and is not to be taken as in any way limiting the invention.

In the embodiment of Figs. 1 to 5, inclusive, the inner track rails 50 are provided with offsets or recesses in their upper surfaces, these recesses being aligned longitudinally of the machine and, in these particular figures, being shown as disposed between the main sills 51 below the position normally occupied by the forming wire 30. The recesses 80 are each of a width to receive the width of the widest forming wire to be used on the particular machine, and each is of a depth to receive. the thickness of the wire 30 and a removable pad rail 81 which is introduced into the wire loop and placed in the recess 80 upon the lower or return run of the wire after it is arranged in the recesses 80, it being understood that there is one pad rail 81 for each recess. 80. The arrangement of the pad rail in the recess with the wire between the rail 50 and the pad rail 81 is shownmore or less diagrammatically in Fig. 4, the upper surfaces of the removable pad rails 81 preferably lying substantially flush with the upper surfaces of the rails or tracks 50. The wire 30, while relatively fragile and otherwise easily injured, has great strength and resistance to injury in compression and, with the bottom run of the wire disposed in the recesses 80 and between the cross rails 50 and the pad rails 81, the table 5 may be rolled or moved over the pad rails without injuring the wire, notwithstanding the sustaining of the weight of the machine by the cross rails throughthe wire itself and the upper pad rails.

The broad aspects of the foregoing pad rail features are predicated upon my co-pending application Serial No. 307966, filed Sept. 24, 1928, and upon the co-pending division of that application, Serial No. 431,734, filed Feb. 27, 1930, and these features, which are, so far as I am aware, broadly new, are intended to be covered in their broader aspects by the claims of said co-pending divisional application. These pad rail provisions, and the manner of application of the wire therewith, enable making the rails 50 as heavy as desired, to sustain the weight of the machine and, at the same time, being always outside the wire loop, the problem of applying and removing these rails with each wire changing operation is avoided. These rails may be arranged permanently in place and the possibility of injuring the wire by introducing them into and removing them from the wire loop with every wire changing operation is avoided. The time element of replacing the wire is also reduced, and this is all particularly important in present day machines which are of great width and in which the rails for carrying and guiding the removal and replacement movement of the table or other parts are necessarily exceedingly heavy. The elimination of the necessity for handling these heavy parts is advantageous, and this advantage is further pronounced in the wide present day machines in which these rails necessarily become exceedingly long. It has been proposed to hinge these rails to one of the side sills, but the wide machines of the present day make it necessary to make the rails exceedingly long and heavy,- and it is not only a difficult or practically impossible matter to swing them completely clear for the wire changing operation, but, again, after application of the lower or return run of the wire below these long heavy rails, it has been necessary to swing them over this wire, all of which is avoided with the pad rail provisions above referred to.

Another important advantage is that with these pad rail features it is only necessary to clear the recesses 80 or substantially the width of the wire, and it is unnecessary to completely clear the rails 50 which has heretofore been necessary in .order to free the rails for carrying and guiding the movement of the table to permit. removal or swinging of said rails up toward the side sills with each wire changing operation. This reduces the amount of movement which must be imparted to the table or other parts'and decreases the'ais space necessary in changing the wire. i

In order to place a new-wire on the machine the old wire may be removed in the usual or any suitable or preferred manner. Where the couch roll is of the cantilever type it may be clearedv for application of the wire in the usual manner and where the couch roll is of the non-cantilever type the porter means 27 (Figure '7) may be applied to the couch roll 22' and, by the application of a chain fall 28 from a suitable crane or in any other suitable or preferred manner, the outer end of the couch roll 22 is released from the removable block 26 sufficiently to permit removal of the block, the bolts or other fastening means being,

of course, first removed.

The wire spool 83, upon which the .wire 30 is wound and on which it is supplied to the user is then brought forward in line with the couch roll 22 which is cantilevered in the usual manner as well understood in the art, the wire being unwound in the usual manner sufiiciently to permit slipping the endless wire loop over the outer end of the couch roll and carried along the face of said roll.

The table S-preferably has suitable supports 84, shown diagrammatically in Figure 5, which normally rest upon block 85 on the permanent sills 51 and the rollers 55 may be journaled upon cam lifts 86 (Figure 14), which cam lifts 86 are splined or fixed upon shaft 87 suitably fixed in the brackets 56. This is merely illustrative and may be varied or omitted, as desired. The blocks 85 are preferably under the dead rail section only, that is under the framework '7 which carries the flat boxes 41. There are therefore preferably no blocks 85 for the first three pad rails counting from the breast end of the machine. The rollers 55 are freely rotatable about the outer journaling surfaces of the cam lifts 86 and by turning the shaft 8'7 as by power or by means of a hand wheel or suitable tool, the high portions of the cams are brought into position at the bottom instead of at the top and thereby lift the rollers 55 from cooperation with the tracks, so that the machine may normally have fixed support and suitable attachment upon the permanent sills.

The details of the preceding cam lift mounting of the rollers is illustrated in Figure 14.

With the wire loop applied over the couch roll, as already explained, the frame assembly may be broken and the weight of the table 5 may be transferred from the supports 84, 85 on the main sills 51 to the rollers 55 and cooperating tracks by turning the cam lifts 86 into position with the high or wide parts below the shaft or pin means 8'7, thereby camming the rollers 85 downwardly into cooperation with the tracks and lifting the supports 84 slightly to free them from their support upon the block 85.

The pad rails 81 are introduced into the recesesses ,80 of the rails 50 and the table assembly is rolled out into the aisle to the position shown in dotted lines in Fig. 1. The pad rails 81 are removed and the wire spool 83 is carried back to the breast end, the wire 30 unwinding from the spool, to the position shown in Fig. 3, suitable poles 90 or other suitable wire stringing means being placed transversely through the wire loop. 30 at the ends and along the upper run of the wire as shown in Fig; 3. The transverse wire stringing elements 90 may be in the i'orm of cables with or without pipes or other coverings, or the wire may be strung in accordance with my copending application Serial No. 431,734, filed Feb. 2'7, 1930, or in any other suitable or preferred manner. The elements 90 at the breast end may be supported in brackets 91 on the head box, as shown in Fig. 3, and the othe'r'elements 90 may be extended transversely through the loop and anchored at opposite sides of the room or otherwise suitably supported. The lower run of the wire loop is placed in the recesses 80, as illustrated in Fig. 4, and the pad rails 81 are placed inside the closed loop and in the recesses upon this lower run of the wire, clamping the wire 30 securely between the rails 50 and the pad rails 81 and spreading the bottom run of the wire so that the loop will have clearance on all sides for the return of the table assembly 5.

Referring to Figs. 1 and 3, it will be noted that by moving the table assembly out diagonally toward an extension of the couch roll, the table assembly has shifted toward the couch end in a diagonal direction so as to provide clearance so that in returning the table the back side of the breast roll end will enter the loop 30 at a substantial distance from the end of the loop as spread by the members 90, and as the table structure is moved back into its normal operative position it enters the loop 30 with sufiicient clearance to pass all parts into the loop and gradually,

by the diagonal movement, the table is extended back from the position shown in dotted lines in Fig. 1 to the normal position shown in full lines 'in Fi 1.

The pad rails 81, which are relatively light in weight and preferably rigid, are then conveniently removed from the inside of the wire loop, and the weight of the machine is transferred from the wheels 55 to the supports 84, on the main sills and, if desired, may be suitably fastened in place. Spread poles are removed and the machine is ready for operation. Of course, in placing a new wire upon the machine, the roll 31. is removed until the table is moved back into the loop and the pad rails 81 removed, whereupon,'the lower run of the wire is lifted and the roll 31 placed beneath the' same and its bearing brackets 92 on the truss rails 6, as shoyvn in Fig. 2. The roll 21 and the stretch roll 29 may also be removed, or the roll 29 may be adjusted as desired, and where there are additional rolls, as may frequently be the case, those rolls disposed beneath the lower run of the wire 30 are removed and replaced in the manner of the roll 31.

In the movement of the table structure back into the wire loop, the removable breast housing part 8 moves into position upon the stationary part 9 and is'supported thereon in the normal operative position of the machine. Not only is breaking and longitudinal telescoping of the table structure eliminated, but, with the present invention, both the table structure and the couch rollsupports are solid andunbroken at all times and, with the present invention, it is unnecessary to remove andreplace the table rolls 40.

4 While the table 5 is shown as being moved diagonally clear of the rails 50 in its removed position in Figure 1, it is to be understood that this movement need only .be suflicient to clear the recesses an or the'width' of the wire, as already explained.

In Figure 6 all parts corresponding to similar parts in Figures 1 to 5 are designated by primed reference characters corresponding with the reference characters used in connection with Figures 1 to 5. The only difference is that in this case the ofi'sets or recesses 80, instead of being provided in the inner rails 50 are provided in the extension or aislerails 52'. In this case, instead-of removing the table, stringing the 'wire along the position occupied-by the table in its normal. operative position and then moving the table back into the wire loop, the wire loop 30' is'strung in the adjacent aisle, whereupon the table is removed from its support upon the main sills 51' and is moved out diagonally ihto the wire loop, which is returned with the table structure in its return movement to operative position.

Where a relatively stationary cantilevered couch roll is employed, as in Fig. 1, the removable block is removed from beneath the outer end and the wire loop is moved back with the table in its movement to its normal operative position, the couch end of the closed end of the loop being slipped over the freed end of the couch roll and the diagonal return movement of the table gradually takes up the slack and extends the machine back to its normal operative position within the loop. This manner of employingthe invention is suitable where the bearing means for the outer end of the couch roll is smaller than, or confined within, the diameter of the couch roll when the removable block is removed, but this manner of carrying out'the invention may be employed as and where suitable or desired.

. In the embodiment of Figs. 8, 9 and 10, both the table structure 5a and the couch roll 22a are removed from normal operative position, the table structure being in a diagonal or intersecting direction with reference to, an extension of the couch roll and the couch roll at right angles to the longitudinal dimension or main sills 51. This embodiment is particularly suitable-for rebuild ing the present type of'Kutter-Trowbridge adjustable table Fourdriniers into quick wire changing machineswithout changing the operation or construction principles of the machine. The wire 30a'is shown as being strung in the aisle along the machine in the manner of Fig. Band the table structure and couch roll are moved out into the wire loop which is moved into nor-. mal position with the return of the table struc-; ture and couch roll into normal operative position, the relative diagonal movement between the table structure and couch rollcontracting the length from the couch end to the br'east'roll end to allow slack for insertion of these parts into the wire loop and the relative diagonal movement upon the return of the parts to normal position extending the breast roll end to its normal operative position with reference to' the couch roll. It is to be understoodthat, in this embodiment, as in the preceding embodiment, the table structure and couch roll may be removed from normal position and that the wire may be strung along the normal position occupied by these parts betweenthemainsills ofthe machineandthetable structure and couch roll then moved back into the loop.

In this embodiment the side truss rails are designated at Go, the side frames at 7a, the removable breast roll housing part at 8a, the stationary breast roll housing part at 9a, the longitudinally extending shaking table adjustable rails at 10c, the vertical tie members at 11a having swivel and universal joints at 12a and 13a, respectively. A shake beam assembly is designated at 14a having means at 16c and 17a for transmitting the shaking action to the shaking part of the table.

Extending from 18a to 19a are the usual dead rails 20a which do not shake, and 21a is the guide roll, and 22a the couch roll, and 40a the table rolls, and 41a the suction boxes, the removable block normally beneath the outerv end of the couch roll is designated at 26a, the breast roll at 36a, the tension or stretch roll at 29a and the head box at 43c.

At 95 are rolls next-to the suction couch roll 22a and on the frame 7a. At 96, 96a, 96b and 960 are similar rolls on .the truss rail frame 6a. The two rolls 95 and rolls 96a and 960 are used to support the bottom run of the wire as it is carried back to normal position, and the rolls 96 and 96b are within the wire loop on the truss rail 6a. These rolls 96 and 96b need not be disturbed at any time.

The inner diagonal tracks or rails a across the main longitudinal sills 51a correspond with the rails 50 of the previous embodiment, and the extension rails 52a correspond with the extension rails 52 of the previous embodiment. In this case the extension rails 52a are staggered with reference to the rails 50a instead of being in alignment therewith as before. With this arrangement the number of rails used may be reducedwithout forsaking any of the necessary guiding and supporting of the table structure thereby.

The rollers on the table structure for cooperation with the diagonal rails are indicated at 55a,

' and blocks 85a are shown on the main sills 51a for supporting the table structure on the main sills 51a in its normal position as in the preceding embodiment.

The rollers 55a may be provided with cam lifts as in the preceding embodiment, or with other suitable means for transferring the machine to the supports 84a, 85a on the main sills 51a in the normal position of the table, or to the wheels 55a for movement into and out of normal position. The rails 50a, 52a are preferably of pad rail construction, as in the previous embodiment, with the recesses for the wire and pad rails disposed below the normal position of the wire between the sills 51a, as in Figs. 1 to 5, or in the rail extensions 52a, as in Fig. 6, depending upon whether the machine is to be moved out into the wire loop in the aisle, or moved out and then back into the wire loop in position between the main sills.

In this embodiment, a pair of rails 100 are disposed beneath the couch roll 22a and at right angles relative to the sills 51a, and these parallel right angle rails 100 have extensions out into the aisle, which extensions may be made integral therewith or separately therefrom. The couch roll housing or bearing ends are provided with rollers 102, one pair being shown at each end of the couch roll, these rollers being preferably flanged or otherwise formed to track upon the rails .00 and guide the couch roll at right angles from and back into normal position. These rolls, too, may be provided with cam lifts or other means construction with the pad rails disposed between the sills or out in the aisle, depending upon the disposition of the pad rails for the rails 50a, 52a.

Power means is again shown for moving the table from and into normal position, but again this means is illustrative of any suitable means, power or manual, for this pupose. The particular power means shown is similar to that shown in connection w'th Fig. 1, except that the shaft 62a is sectionalized with the sections 105 geared to the sections 106 by bevel gears 107. The shaft sections 105 are disposed at substantially right angles to the diagonal movement of the table structure so that the sheave pulleys'lla, carried by and rotatable therewith, will be disposed to exert a direct pull upon the table structure through the cables 72a instead of at an angle to the diagonal movement, as in the previous embodiment. The hooks 73a, eyes 74a, and pulleys 75a, correspond with the hooks 73, eyes 74 and pulleys '75 of the previous embodiment and the manner of attaching the cables 72a, either directly to the table structure or around the pulleys 75a and then to the table structure for moving this structure either inwardly to normal position same as in the previous embodiment and will not v be repeated. 1

An additional sheave pulley 108 is provided for the couch roll 22a, this sheave pulley being adapted for winding a cable 109 which is adapted for connection at 110 with the rear end of the couch roll structure, either directly or around the pulley 112 in the manner of the connection of the cables 72a to the table structure.

It will be noted that, in removing the table structure and couch roll into the aisle and in moving these parts back into normal position, the table structure, because of its diagonal or intersecting movement, must travel a greater distance than the couch roll structure along the right angle rails 100 in each direction. To provide for this, I have shown the pulley 108 as being smaller than the pulleys 71a, so that upon application of power to the shaft 62a the pulleys 71a, around which the cables 72a are wound, will cause the table structure to move at a faster rate of speed than the couch roll structure, these pulleys being preferably proportioned so that the table and couch structures will reach their normal position and their removed position at the same time in spite of the different distances traversed thereby. Of course, with the sectionalized shaft structure shown in Figure 8, the gearing might be proportioned to provide this result.

The wire stringing devices 90a, in Figure 8, are similar to the poles or wire stringing devices 90 in the previous embodiment, and are illustrative of suitable means for this purpose, which means is operable in the manner previously described.

Referring to Figure 8, it will be noted that the couch roll 22a is shown both with a direct canti- This is broadly new, as all removable Fourdrinier machines heretofore have had to be moved completely from the longitudinal axis of the forming wire and completely off of or beyond the supporting rails on which the frame normally rests.

For the purpose of adjusting theforming elevation of the Wire at the breast end of the machine of Figures 8, 9 and 10, the part 9a previously designated as the stationary breast roll housing part, may be in the form of an adjustable supporting jack having a screw housing 120 journaled at 121, 121 to swing laterally and having pin or trunnion means 122 at the head of the same for engaging cooperating bearing surfaces in the bottom of the removable breast housing part 8a. The part 8a rests upon the cross pin 122 when the removable table is in normal position and the table is supported at the breast end of the machine thereby. At the same time, the support at this point with the rocking support at the lower end of the housing 120 and 121, 121 will permit a lateral rocking action of the support. 'A capstan nut, or other suitable means '123, is adapted for raising and lowering the screw 122 for adjusting the elevation of the breast end of the machine. In vertically adjusting the breast end of this machine, the table is released by transferring the weight to the rollers and cooperating rails. This may release the part 8a sufiiciently from the part 9a to permit lowering the screw 123 until the rocker pin 122 isclear of the cooperating seats in the bottom of the part whereupon the table structure with the breast roll 36a and part 8a are adapted to be removed and, when replaced, the breast roll adjustment may again be brought up as shown in Figure 10.

At 126 thehead box 43a is shown as having the usual adjustable section which is adapted to raise and lower with the adjustable table. At 127 is an angle arm or bracket bolted to the frame 6a and adapted for preventing the breast-roll assembly from swinging, in a clockwise direction when in the position shown in Fig. e.

I While it has been proposed, heretofore, to support the save-alls on the table structure in some types of machines, such as the Kutter-Trowbridge adjustable table machines, the save-ails have been made up in segments supported on stands bolted to the floor and not adjustable. The Kutter- Trowbridge machines used an obsolete wire stringing system in which the save-alls and all other parts were removed in segments from the frame. Many of these save-all systems are in excellent condition, and I provide for using the same in rebuilding this type of machine into a quick wire replacing machine in the following manner:-

In Fig. 9 is shown a stand 130 normally resting 'upon the main sills of the machine and having an adjustable arrangement. At 131 is a swivel joint bolted to the frame section 7a, these joints 131 supporting rails 132 disposed longitudinally beneath the ,railslOa. Rails 132 rest intermediate the longitudinal dimension of the table on the adjustable stand 130 and are independent of both the shaking action and vertical adjustment of the forming table in normal operation.

At the breast roll end the rails 132' are supported by engagement with a boss 133 on the breast roll structure cross brace 134. This' boss 133 engages the rails 132 should the operator ad-v just the table in operationand the save-all system is adapted to be suspended from its opposite ends without the intermediate support 130 to permit removal and replacement of the system with the table structure. The save-all trays are indicated at 135' and the save-all troughat 136. The adjustable stand 130 can be lifted 01f of the sills by adjusting the screw 137 until the boss 133 takes the load, then, by further adjustment, the lower section of the stand 130 is raised clear of the sill, as shown in Fig. 10. In this manner, the save-all system is adapted to be suspended from the truss frame 6a clear of the sills for whatever table structure movement or wire stringing operation may be desired. 7

I I wish to point out here again that, with the pad rail features, it is unnecessary to form joints between the inner rails 50a and the outer rails 52a, but these parts may be made up integral and permanently secured in place. The position of the rear end of the couch roll structure in Fig. 8, namely, the position of this inner end in the removed position of the couch roll illustrates that it is unnecessary to remove the couch roll completely off of the inner portions of the rails to permit the application of a newwire.

In Fig. 8 the wire 30:: is shown stretched in the aisle with the table structure and couch roll moved into the same, the wire spool holder being shown at 140 for holding the wire spool 141, the surplus wire 30:; being held on the spool 141 in such a manner that as the machine moves back to normal position the expansive action between the breast and couch roll ends produced by the relative diagonal or intersection movement causes the spool 141 to unwind until the wire is fully stretched about the desired parts.

It is believed that with the foregoing descrip tion of the embodiment of the invention shown in Figs. 8 to 10, and with the described manner of placing the wire upon the machine in the previous embodiment, that the operation of the machine and the manner of replacing the wire in Figs. 8 to 10 will be apparent without further explanation.

In order to illustrate that this invention is not confined to moving a particular part or parts diagonally, or in a direction intersecting an extension of the other parts, I have, in Figs. 11, 12

and 13, illustrated another embodiment of the invention in which the couch roll structure is removed from and replaced in normal position in a diagonal direction. In this case the table structure is removed at right angles and, while the wire loop is shown as being strung in the aisle with the table structure and the couch roll structure moved from normal position and into the loop with an accompanying relative diagonal movement between the parts for reducing the distance between the couch roll and the breast roll to provide suitable slack for entry into the loop, it is to be understood that, as in the other embodiments, the table structure and couch roll structure may be removed from normal position with a suitable relative diagonal movement between them, the forming or Fourdrinier wire strung around the space normally occupied by the machine and the table structure and couch roll structure then moved back into the wire loop. In the embodiment of Figures 11 to 13, the diagonal or. intersecting movement of the couch roll structure provides the necessary slack at the couch end of the machine, whereas, in the preceding embodiment, the slack was provided at the breast roll end. It is to be understo d that a combination of intersecting movements might be employed or slack might be provided at either end.

In Figures 11 to 13, the table structure is indicated in its entirety at 150, the couch roll structure is indicated at 151, and the main longitudinalsill members are indicated at 152. The side truss rails 153 correspond with the side truss rails 6a of the embodiment shown in Figures 8 to 10, and the side frames 154 correspond with the side frames 7a. The removable breast roll housing part is indicated at 155, the stationary breast roll housing part at 156, the table rails at 157, with tie members 158 connected between them and the truss rails 153. The rails 157 extend from swivel joints 159 on the breast roll' bearing to universal joints 160 on the side frames 154. Rails v161 are bolted at one end at 162 to the side frames 154 and, at their opposite ends at 163 to said side frames.

The table rolls are indicated at 164 and, as

before, these need not be disturbed in placing a new wire upon the machine. Suction boxes are indicated at 165 and at 166 is a guide roll. The breast roll is indicated at 167 and the suction couch roll proper, 168, has a reduced neck 169 at the front side and reduced neck, cantilever, direct lug clutch drive 170, 171 at the rear side. This suction couch roll is, in accordance with the present invention, converted into a removable couch roll and, at 172; is shown a suction pipe connection therefor, which is broken or disconnected at the flange 173 only to'permit the removal and replacement movement of the couch roll in accordance with the present invention.

. With the machine in normal position, the suction connection 172 may be bolted or otherwise sum ably secured at 173 to the suction line 174 (Figure 13) and, to permit movement of thesuction couch roll structure, all that is necessary is to break this connection at the flange 173.

- A series of carrying rolls 175 and 176 are shown, and, on stringing a wire, rolls 175 and rolls 176 are removed, and, on placing a wire over the machine, as shown in Figure 11, the rolls 175 and 176 are preferably placed back into the position of Figure 13 so as to support the bottom or return run of the wire as the machine carries the wire back to normal position between the sills 152. Cross braces 178 are preferably provided within the wire loop, and a boss 180 on the breast end cross brace 181 may support the save-all system, as described in connection with the embodiment of Figures 8 to 11.

The save-all system of the preceding embodiment may be employed in connection with this embodiment of the invention, but has been omitted from the drawings for clarity. The rolls 182 within the wire loop need not be disturbed in placing a wire upon the machine, nor need the stretch roll, indicated at 183 be disturbed.

The table structure 150 is arranged to be run out at right angles on tracks 189 disposed at right angles across the main sills 152 and upon extension or aisle tracks extending out at right angles from the front sill and designated at 190 in Fig. 11. At 191 wheels secured to the front frames 153 and 154 are arranged to cooperate with and travel on rails 190, and at the rear the table structure 150 is provided with rollers 192 arranged to travel on the tracks 189. Where the wire 194 is strung out in the aisle and the machine parts moved out into the wire loop, the rails 190 are preferably of pad rail formation, as described in connection with the embodiment of Figs. 1 to 7. The inner rails 189 may be securely bolted to the base structure and need not be removed. While it is not necessary to remove the outer rails 190, these rails may be removable for clearing them-from the aisle in normal operation of the machine. It will be noted that rails 189 and 190 are at right angles to the longitudinal dimension of the machine. Therefore, the wheels 192 cannot ride on the rails 190, nor can the wheels 191 ride on the rails 189, and none of the wheels are, therefore, moved across a jointed rail track as heretofore.

The couch roll structure 151 is arranged to be run out 'in a diagonal or intersecting direction toward the table structure on diagonal inner rails 195 and diagonal outer rails 196. At the rear the couch roll structure is provided with rollers 197 which track on the diagonal rails 195 and at the front of the couch structure are rollers 198 which track on the rails 196. Shaker means is indicated at 200 with means 202 for transmitting the shaking action to the shaking part of the table structure in any suitable or preferred manner.

In this embodiment, the rollers 191, 192 are shown (Figs. 12 and 13) as being mounted on adjustable screws 204, secured in members 205 bolted to the truss frame 153. At 206 are a series of blocks mounted upon the main sills 152 or other base structure, and the machine normally rests upon these blocks and may be rigidly fastened to the base structure as described in connection with Figs. 1 to 7. By loosening the lock nut means 208 and manipulating the screws 204. the rollers may be lowered with respect to the frame structure of the table to raise the adjacent part of the machine for a purpose which will hereinafter appear. Similar adjustable screws may be employed at all of the rollersfor transferring the support of the machine from a direct rigid support on the side sills to a rolling support on the rollers and rails instead of the cam lifts described in connection with Figs. 1 to 7.

To place a new wire on the machine, the diagonal aisle rails for the couch roll structure and the right angle aisle rails for the table structure are arranged in position, as shown in Fig. 11, and the win 194 is strung along the aisle and supported by the member 210 at the breast end and member 212 at the couch end, these members 210 and 212 being shown as provided with eye bolts 214 for supporting the cables or other wire stringing members at opposite ends upon the walls or other supports.

The lower rim of the wire is arranged across the rails 190 and 196 and the pad rails are placed in position within the loop and upon their respective rails in the manner described in connection with Figs. 1 to 7. The weight of the couch roll structure is transferred to the wheels 197 and 198 and the couch structure is now shoved or otherwise moved out into the aisle in the manner previously described, or in any other suitable manner and into the wire loop. Upon moving the couch structure into the wire loop, the pad rails are removed from within the loop and the member 212 may then be removed to permit the wire to rest on the face of the suction roll. The member 210 is then extended to the position shown at 210a in Fig. 11. This permits the table structure to be moved out into the wire loop on the staggered rails 189 and 190.

The adjustable supporting means 156 corresponds to the adjustable'supporting means 9a of the preceding embodiment with the movablein operation with a forming wire and having truss end of the table structure until the bearing 155 clears the pin 220, as shown in Figure 12. In this manner, the adjustment of. the jack means 156 need not be disturbed to move the breast truss end from its support on this means and back to normal position. The table is movedout into the wire loop, and the pad rails for the table tracks are removed, the excessive slack being taken up on a wire spool 225 resting in a block 226 on the couch roll structure. The rolls 176 are then placed in their bearings and themachine is ready for movement back to normal position by power or any other suitable means. In the return movement, the table structure travels at right angles to the longitudinal dimension of the machine and the couch structure moves in on a diagonal, oblique or at an intersecting angle away from the table and, as the movement on the diagonal rails extends the remote parts of the machine, one part from the other, the wire 1% on the blocks 225 unwincls until the normal position of the machine onthe main sills is reached. This unwinding of the wire from the spool 225 as a result of the diagonal travel of one part of the machine is so far as I am aware broadly new. The machine is then lowered onto .the supporting blocks 230 which correspond with the blocks 85 in Figure 4, the rolls 175 and 176 are placed in their bearings, the breast. end bearing lowered onto the pin 220 by means of the adjustable screws 204 and all parts are in normal position with the wire in place.

It is to beunderstood that where power means is used for moving the table and couch roll structures out into the aisle and back into normal position, that the diiferenti'al drive of Fig. 8 will'be reversed to cause the couch roll structure to travel faster than the'table roll structure, so that these structures will be aligned in normal position and in the aisle, notwithstanding the greater travel necessary in the couch roll structure because of its diagonal or angular direction. As the couch roll'structure is moved back to normal position, the directlug clut'ch drive 171, 170 is engaged and, if necessary, the clutch teeth may be formed on an angle to permit this' engagement by the diagonal direction of the couch structure.

Aside from the other advantages already referred to, this arrangement permits stringing the wire on a modern machine with only enough aisle space to pick up the width of wire. Heretofore, all modern machines using the previous types of removable Fourdriniers require an aisle substantially one and one-half times as wide as the machine, and ithas been impossible to remove a' cantilever or direct drive suction roll a suflicient distance off of themain silis to string the wire even where the front aisle is one and one-hall times the width of the machine. Therefore, in

. order to convert or rebuild a machine having a direct drive or cantilever arrangement, it has not heretofore been possible to use the original roll. With the present invention, these disadvantages are all avoided.
