DECKLING MECHANISM IEON lPdl lE lt-llttdiidlNtil hllidt'lll-IIN Application filed January 3, 192%. aerial Tito. Wttfil'ttt.

This invention relates to deckling mechanism for paper making machines, and has for its principal object, to provide improved mechanism for eflecting the declrling operation on the wire of a paper making machine, "for instance, on the hourdrinier wire of a l ourdrinicr paper making machine, and also to provide deciding mechanism operative between the stock-tioW-regulating plate and apron over which the stoclrtlows from the head box to the wire or other stock receiving part, in the case of a so-called Voith inlet.

@ther objects of the invention are to provide an eliicient declrling device of simple construction tor use between the regulating plate and apron above referred to; to provide such a dcckling device which is adjustable crosswise of the machine between the regulating plate and apron to vary the width of the flow of stock therebetween; to provide such a device which is adjustable to closely lit the vertical dimension or depth of the space between the regulating plate and apron, and also to provide such a device which is automatically self-adjustable to tit the depth of said space.

lfurther objects of the invention are to provide improved means for mounting the deckle strap guide pulley ot a standard type of paper making machine so as to permit movement thereof from its normal position, thereby to facilitate repairing, cleaning or other operationson the wire or other parts to which access is otherwise obstructed by the pulley and its support; to provide improved means for effecting adjustment of the declrle strap for controlling the width of the flow 0t stock on the wire, and to provide means whereby the decide strap and the abovenicntioned deciding device may be simultaneously adjusted as a single unit. v

Other objects and advantages of the involition will be understood by reiterence to the following specification and accompanying drawings in which we have illustrated so much of a Four-dimer type oi paper making machine as is necessary to enable a person skilled in the art to tally understand the present invention.

in the drawings:

lli'eterring now more particularly to Figures l and 2 oil the drawings, the head boa ot a paper making machine is indicated at it), supported by any suitable trameworh lit and provided with a discharge opening 12 in. its

front wall 13. it. distributor roll ll ct any desirable term is rotatably mounted in bear ings such as shown at 15 on opposite sides oil the head hon and serves to produce aunitorm distribution oil the iibers contained. in the paper stoclt as it tlows out ot the head boa through the discharge opening l9 For controlling the discharge opening l2, a gate 16 is provided which is adjustable vertically to open or close the opening asdesired. This gate is suitably mounted in grudeways, and means may be provided tor facilitating adjustment thereot and also locle ing the gate in the desired position, tiuch means forms no part at the present invention and theretore need not be specifically de scribed A wire 17 (tor instance, a ll ourdrinier wire) passes around a breast roll ltd and a couch roll (not shown) and is supported intermediate the rolls by means oil a plurality ot supporting rolls l9. 'llhe breast roll lit and supporting rolls 19 are, ct course, suitabl mounted in supporting side trainee which are omitted in the present disclosure, since this structure is well known to those skilled. in the art. it declrle strap 20 and deckle-strap'guide pulley 21 are arranged over the wire 17 so that the lower reach 20 ot the strap will be ett'ective to control the width ot the How of stoclr on the wire. lthe guide pulley 21 is rotatably mounted in an improved manner which will hereinafter be tully de scribed. lt or conveying the paper stoclr from the head box it) to the wire it, the head boa 10 is provided with a bottom. plate which ltltl ltlti or secured to the extends outwardly from the box adjacent the lower edge of the discharge opening 12. An apron 23 of rubber or other suitable material is secured to said bottom plate 22 and supported by an extension plate 24 which extends from the forward edge of the bottom plate 22 to a point in very close proximity to the wire 17 so that the apron is well supported between the forward edge of the bottom plate and the point at which the'apron actually engages and rests on the wire, as shown at 25. The apron, of course, extends lengthwise over the wire some distance beyond the breast roll so as to deliver the Wet paperstock to the wire at the proper point.

For further controlling the depth of the flow of stock from the head box on to the wire, a regulating plate 26 is provided which is preferably pivotally mounted, as shown at 27, adjacent the lower edge of the ad justable gate 16. Suitable means including a clamping plate 28 and clamping mechanism 29 are provided for retaining the regulating plate in its pivotal mounting, and adjust-- ing rods-such as shown at 30 are connected to the regulating plate adjacent itsforward edge for effecting swinging movement of the plate about its pivot. It will be apparent that y raising or lowering the forward-edge portion of the regulating plate, the depth of the flow of stock from the head box on to the Wire will be effectively controlled.

The deckling device for controlling the width of the flow of paper stock between the regulating plate 26 and apron 23 is best shown in Figure 5, and consists of a back wall portion 35 and a side wall portion 36. The back wall portion is preferably formed of a channel-shaped member 37 and a plate 38 which is mounted on the back of the channel so asto be slidable thereon in such a way that it serves, when extended, to increase the width of the back wall portion 35. The plate 38 is so mounted by means of a guide 39 rigidly secured to the end of the back wall,40 of the channel member and provided with an undercut edge portion 41 which receives a complementary edge portion 42 of the plate 38. The other end of the plate 38 is slidably mounted by means of a track 43 integral with plate 38 and fitting over a track 44 projecting from the adjacent end of the back wall portion 40. The plate 38 is also provided with

plunger members

45 and 46 secured thereto by means of

lugs

47 and 48, and the said plungers are slidable through

apertures

49 and 50, respectively, provided in the top wall 51 of the channel member. The

plungers

45 and 46 are recessed, as clearly shown in Figure 6, to receive a coil spring and a spring guide pin 53 which is seated in the lower flange or wall 54 of the channel member. The

plungers

45 and 46, which slide through the

apertures

49 and 50 respectively,

are effective to prevent displacement of the plate 38 from the channel member, and the above described undercut seat arrangement 41 and 42 and track arrangement 43 and -llserve to steady the plate 38 relative to the channel member.

The side wall portion of the deckling dcvice includes a member 55 rigidly secured to the end of the channel member 35 by suitable means such as a screw shown at 56, the adjacent end ol' the channel member being provided with a closure portion 57 which is drilled and, tapped to receive the screw 56. The member 55 is preferably further connected to the channel member by means ol. a diagonal brace 58 which is secured by means of screws, as shown at 59 and 60, to the channel member and side member respectively. The member 55 is preferably wedge-shaped, as clearly shown, to fit between the apron 2;} and the regulating plate 26, which is usually disposed at an angle relative to the apron as shown. An extension member 61 is pivoted adjacent its upper corner, as shown at 62, to the adjacent upper corner of the rear wall extension plate 38. The said side extension 61 is further provided with

guide lugs

63 and 64, which overhang the member 55 so as to position the extension member 61 closely adjacent the outer face of the member 55. and a spring member 66, secured as shown at 67 to the member 55 and engaging thelug 64,- is effective to normally tend to swing the outer end of the side extension 61 upwardly about the pivot 62, thereby to in- .crease the effective width of the wedge-shaped side. The springs 52 which operate in the

recessed plunger posts

45 and 46 normally tend to force the back wall extension plate 38 outwardly to increase the effective width of the back wall. Hence it will be seen that the deckling device is automatically adjustable to accommodate itself to closely fit the depth of the space between the adjustable regulating plate 26 and apron 23. i

The above described deckling device is mounted between the regulating plate 26 and apron 23 so as to be slidable cross-wise of the length ofthe paper making machine in such a way that the extensible back wall portion ot'thedevice is effective when the device is adjusted inwardly to close the end portion of the discharge opening 12 in the head box and so that the extensible side wall portion of the device is effective to controlor guide the adjacent edge of the flow of stock between the regulating plate and apron. It

will be apparent that if the gate member 16 is adjusted so as to increase or decrease the height of the discharge opening 12, the deck ling device, because of its spring-actuated extensible back-Wall portion will be automatically adjusted to compensate for the adjustment of the gate 16. The spring-actuated extensibility of the side wall portion of the deckling device also results in automatic intense adjustment of: the side wall to accommodate itself to any adjustment of the forward edge portion of the regulating plate 26 which may be accomplished through the adjusting rods 30.

For facilitating adjustment of the deckling device crosswise of the machine, we provide an arm 68 integral with the brace 58', and this arm 68 may be provided with a hand grip for permitting convenient manual adjustment, or an arm may be provided with means for attaching the same to mechanism whereby such adjustment may be effected. In the present instance, we provide the arm 68 with an upstanding lug 69 which is adapted to be connected to mechanism which will herein after he described for effecting the said adjustment.

Any convenient mechanism may be provided for locking the deckling device in any desired position of adjustment between the regulating plate and apron, and in the present instance, we provide a clamping arm 70 which depends from a bracket T1 secured to the front wall 13 of the head box. A stud 72 secured in the front wall of the head. box beneath the bracket 71 extends through an aperture in the clamping arm and rotatably receives a cam member 73 provided with a handle T l whereby the cam member 78 may be rotated. A cam member is fixedly secured to the clamping arm 70 so that rotation of the cam member 73 forces the lower end of the arm 70 into engagement with the edge of the top wall 51 of the channel member, thereby to clamp the deckling device between the portion of the head box which it engages and the clamping arm.

The deckle strap guide pulley 21 is rotatably mounted on the inner end of ashaft 80 and is locked thereon against axial movement by means of

collars

81 and 82 which are nonrotatably secured to the shaft. A. guide linger 81 integral with the collar 81 is provided for preventing the deckle strap from leaving the guide pulley adjacent the top of the latter, and a paper stock guide 81 issupported by means of a hanger 81 secured to the said collar 81. The guide 81 serves to guide the edge of the flow of stock across the space between the forward end of the deckling device and the adjacent portion of the deckle strap. lhe shaft 80 is axially slidably mounted in a bearing 83 forming one part of an arm 84: which is pivotally mounted on a vertical axis at its opposite end, as best shown in Figures 1 and 2. For the purpose of so mounting the arm 84, we provide a bracket 85 which is pivoted to the side wall of the head box 10 by means of a bolt'88 and. which is locked against pivotal movement about the bolt 80 by means of bolts 8'? and 88 which pass through slots89 and 90, respectively provided in the bracket member. The bracket member 85 is provided with spaced cars 91 and 92; between which a tongue portion 93 of the arm 84 is disposed and pivoted by means of a pivot bolt 94. The tongue portion 93 of the arm is provided with a slot 95through which a bolt 96 passes intothreaded engagement with the side wall of the head box.

It will be apparent that by loosening the

bolts

87, 88 and 96, the arm 84; and bracket 85 may be swung in a vertical plane about the pivot bolt 86, and hence that a certain degree of vertical adjustment is provided for the deckle strap guide pulley 21 and the deckle strap 20'. It will also be apparent that by removing the bolt 96, the arm 84- may be swung in a horizontal plane about the pivot bolt 94, thereby permitting removal of the deckle strap guide pulley from its normal position over the wire 17, and thereby atfording free access to parts of the machine to which access is otherwise obstructed by the deckle strap guide pulley and its supporting arm.

The outer end of the shaft 80 is axially slidably mounted in a suitable bearing 99 provided as a part of the arm 8d. .Elr shaft 100 provided with screwthreading, as shown at 101, thrcadedly engages an apertured boss 102 also provided on the arm 84 intermediate the bearings 88 and 99, and the outer end of the shaft 100 is rotatably mounted in the connecting arm 98,.but locked against axial movement relative thereto by suitable means such as a collar 108 and a hand wheel 10%, both of which are rigidly secured to the shaft 100.

. lit will be readily understood that by turning the hand wheel 104 and shaft 100, the con necting arm 98 will be caused to move towards or from the supporting arm 84. Such movement-of the connecting arm 98 relative to the supporting arm is effective to move the

shafts

80 and 97 axially through their respective bearings, such movement of the shaft 80 being efi'ective' to correspondingly adjust the deckle strap guide pulley crosswise of the length of the paper making machine. Hence it is a very simple matter to adjust the deckle strap inwardly or outwardly crosswise of the inachine'to control the width of the flow of stock as'it is deposited on the wire.-

For adjusting the deciding .device between the regulating plate and apron, we provide an arm 105 rigidly secured to the connecting arm 98 by means of bolts such as shown at 106, and to the lower end of which one lug 10.7 of

a lit-shaped bracket 108 is rigidly connected.v

The other lug 109 of the d-shaped bracket is connected by means of a bolt 110 to the In}; 89 of the arm 68. ll/loven'icnt of the connecting arm 98 will be transmitted through the arm 105 and bracket 108 to the deckling device, and hence rotation of the hand wheel 10 i is operative/to simultaneously adjust the deckle strap and the deciding device.
