REMOVABLE-TYPE FOURDRINIER IPAIPER-MAKING MACHINE.

Application filed April 16, 1926. Serial No. 102,388.

This invention relates to a removable type Fourdrinier paper making machine and more particularly to a Fourdrinier wherein the couch and breast rolls are removable with the table structure as a unit to facilitate the changing of wires.

In my copending application, breast roll transfer mechanism for Fourdrinier paper making machine, Serial No. 727,638,. filed July 23, 1924, now Patent No. 1,599,402, issued Sept. 14, 1926, I have described means for transferring the breast roll from a separate support to the table structure for removal thereon during the changing of wires. I now propose to embody the principles of that invention in my present construction and also to provide means for supporting the suction roll either permanently or temporarily upon the table structure. By such a combination, the ease with which wires may be changed on the machine is greatly increased.

It is, therefore, an object of this invention to provide a removable type Fourdrmier paper'machine wherein the couch roll may be supported on and removed with the removable table structure.

It is a further object of this invention to provide a Fourdrinier having a laterally re- -movable table and a suction couch roll normally mounted on said table and removable therewith as a unit.

It is a further object of this invention to provide a Fourdrinier having a laterally removable table, breast and couch rolls sep arately mounted from said table and means for transferring said breast and couch rolls table for removal therewith.

it is a further object of this invention to ride a laterallyremovable Fourdrinier of paper machine wherein the couch and breast rolls are adapted to be moved relatively towards or away from each other llhe invention a preferred form) is illustrated in the accompanying drawings and hereinafter more fully described.

Un the drawings: Figure l is a side elevational' dlagrammatic view of the Fourd'rinier end of a paper machine, with parts broken, showing the preferred form of my invention.

Figure 2 is a top plan view of the laterally removable table structure shown in Figure 1, showing theoperation in dotted mes.

Figure 3 is a fragmentary view of the couch roll and couch end of the Fourdrinier frame showing amodified construction.

Figure 4 is a view similar to Figure 3 showing a second modified form of construction.

, As shown on the drawings:

In Figures 1 and 2, the reference numeral 1 indicates one'of a pair of I beams-forming the side rails of a'laterally removable Fourdrinie'r table structure, and supporting the usual table or tube rolls 2 and suction boxes 3. Said table structure, together with the tube rolls 2 and suction boxes 3, is adapted to be laterally removed by rolling the same out on rollers 6 over tracks 4, which may be swung out or otherwise moved into the position shown in Figure 2, parallel to and forming a continuation of tracks 5 on which the table structure normally rests. Said rollers 6 are supported is bearing brackets 7 from the table rails 1 and are operated by means of a driving means 8 through the connecting shafting 9. The rails 5 are supported on pedestals 10, one end of each of said rails 5 being provided with a pivot post 11 and the other end being adapted to be locked in normal transverse position by locking means 12. The structure and operation of my removable Fourdrinier table is slmilar to that described in the copending application to Alonzo Aldrich and myself, removable type Fourdrinier paper making machine, Serial No. 57,272, filed September 19, 1925.

The breast end of the machine'coniprises a breast roll 13, having journals 14 removably mounted on a supporting pedestal 15. An apron 16, suitably mounted in front of said breast roll 13, conducts the stock onto a wire 17 running around said breast roll 13 and over the tube rolls 2 in the usual manner. Wire guide rolls 18 and stretch rolls 19 are positioned substantially as shown.

llhe breast roll 13 is adapted when a Wire is to be changed, to be removed from the pedestal 15 over onto supporting brackets or shelves 20 forming a part of the rails, and provided with grooves 21 for receiving the breast roll journal 14. This construction is above referred to.

described in my co-pending application It will be noted that in so moving the breast roll 13 the eflect is to shorten the effective length of the Fourdrinier and to produce the necessary slack in the wire for removing the wire or for slippingpn anew wire, as will be understood by one skilled in the art of paper making.

At the couch end of the Fourdrinier frame, the'table rails are provided with lower ofiset extensions 22 on which are mounted bearings 23, bolted or otherwise secured thereto. A suction couch roll 24 -is adaptedto be journaled in said bearing 23 so as to be a part of the table structure and to be removable therewith as a unit. A sectional suction line 25 having a removable section 26 is used in place of the usual semi-permanent line to the suction couch roll to facilitate its dismantling prior to moving out the table structure. Said section 26 is provided with flanged ends 27 having circumferential slots adapted to receive bolts 28 pivotally secured to adjacent flanged ends 29 of the suction line 25. hen the section 26 is to be removed, the nuts 30 o'n-said bolts 28 are loosened up and thebolts swung out of the slots. With this section 25 removed, it is then possible to move the table structure out from the rest of the machine. The operation is as follows: The modusoperandi when changing a wire on the machine is substantially as follows: First, the removable section 25 of the suction line is taken out and the tension on the wire is lessened by either adjusting or re. moving entirely the stretch rolls 19. It may also be necessary to remove the guide roll; 18, depending upon the set up ofthe machine. Then the breast roll 13 is moved over from its pedestal 15 on to the table structure, the breast roll journals resting in the grooves 21 of the supporting brackets 20. The moving of the breast roll may be accomplished by a crane or by methods set forth in my application above referred to. The wire 17 being now slack may be supported away from the 'table structure so that the latter may be moved out from the looped wire.

The rails 4 are next moved into position if not already there, and the table structure moved out laterally onto said rails by operation of the motor or other driving means 8.

The inner rails 5 are now swung along parallel to the side structural beams 31 and the old wire wound up and removed.

The new wire is then supported in the position occupied by the old wire, the tracks 5 swung back into normalposition and the table structure run back onto said tracks 5. The breast roll 13 is moved back onto the pedestal 15 and the wire rolls 18 and 19 'returned to their places. The section 26 of the suction line 25 is also slipped into place and bolted securely.

The remarkable simplicity of the above described operations and the improvements represented by my present Fourdrinier construction over former types of Fourdrinier construction will be obvious to one familiar in time and labor is efiected by such improvements.

In .Figure 3, I have shown a modified constrution of the couch "end'of the Fourdrinier. In place of the stationary couch rolls 24 shown in Figures 1 and 2, I provide a removable couch roll 32. supported from a separate pedestal '33. Said. couch roll 32, which may or may not be of the'suctiontype, is journaled in cylindrical bearings 34, which are removably mounted in arcua'te' shaped with paper making practice. A great saving supporting brackets 35, bolted or otherwise I secured to said pedestal 33. The circumference of said bearings 34 is provided with gear teeth 36, adapted to mesh'with teeth 37 formed on the base of said brackets 35. Lo'cking devices are provided to retain said hearings in place comprising uprightslotted members 38 each forming a part. of thebrackets 35, and lug 39 adjustably bolted to said members 34 by bolts 41 and having teeth 40 adapted to be inserted between any two ad-.

jacent teeth 36. 'Set screws 42 are provided to lock the bearings 34 to the journals of the roll 32when the'roll is to be transferred, -A squared stub shaft 43 formed on each of the bearings 34 serves as means for applying a wrench or crank to .turn the roll.

When a wire is to be changed the bolts 41 are first loosened and the locking pins 40 raised out of locking position. The set screws 42 are then tightened to lock the-beanings 34 to the roll journals and a-wre'nch or crank is applied to the stub shaft 43. A bridge beam 44 is next laid to span the gap between each of the pedestals 33 and the lower offset extensions 45 of the Fourdrinier table rails 46. Said bridge beams 44 and extensions 45 are each provided with rack teeth 47 to form a continuation'of-the teeth rate from the Fourdrinier table structure Said table structure includes side rails 51'] having lower ofi'set longitudinal extensions 52 provided with pockets 53 in which the journals 54 of said roll 48 are adapted to rest when the wire is being changed.

In the operation of changing a"wire, the upper halves of the bearings 49 are removed,

and the couch roll 48 is lifted up bodily by 'a crane or other lifting means and deposited on the extensions 52, where it rests during the lateral removal of the table,

Other ways of supporting the couch roll ried by the table structure for removal therewith as a unit when the wire is to be changed. The breast roll should also be carried by the table structure during its lateral removal, but that invention forms the subject ofmy c'opending application above referred to.

It should be noted that in any of the forms of my invention described, there is effected a relative movement of the breast and couch rolls toward or away from each other during the wire changing operation.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing. from the principles of thisinvention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. Ina removable type Fourdrinier paper machine, the combination with a removable table, of a suction couch roll adapted to be supported thereon for removal therewith.
