Glens Fans, N. Y., assis-nor to The Sandy Hill Iron & Brass Works, Hudson Falls, N. Y., a corporation of New York ApplicationI January 15, 1937, Serial No. 120,744 1 Claim. (Cl. 92-43) The principal objects of the invention are'directed to the provision of paper-making appara- 4 tus wherein a cylinder mould is adjustable rela'- tive to the adjacent wall or Walls of the vat in` order to meet various conditions and requirelo ments.

ld between the mould and In paper-making apparatus of the type to which the invention relates a cylinder mould rotates in a vat which is provided with a wall or walls adjacent the mould, there being a space wall for paper-making material, the bers of which are taken on by the foraminous surfacesof the mould.

In order to produce certain results insofar as possible the Wall or walls have been of certain Wcontours and spaced certain distances from the cylinder mould. That is to say, when lt is desired to produce a certain kind of paper it has been customary to locate the `wall or walls adjacent the cylinder mould and so form it in such a way as to provide a certain space between the mould and wall and to use paper-making ma- 'terial of certain consistency and rotate the mould in a certain way. lin other words'gfor certain predetermined results the wall is of a certain W shape and a certaindistance from the cylinder mould, the characteristics of the paper-making material for the particular result are more or less denlte,r and the speed of the cylinder is within a certain range. The space between the cylinder and wall is of course constant and therefore an important factor and the characteristicsof the paper-making materiaLspeed of the cylinder, and other factors within relatively narrow limits.

l ere it is desired or necessary to produce the same kind of paper continuously it is possible to produce reasonably good results but Yit is dicult and sometimes impossible to vary all of the factors to produce equally good results where it is desired to produce other kinds of paper because of the denite relationship of the cylinder and wall. To produce a certain result with papermaking material of certain characteristics the cylinder and wall must have a certain relationship. Where it is desired to product another result with the same or different paper-making materialthe cylinder and wall should have a different relationship. But si ce the relationshipA ls constant it is impossible at times to use the "material desired. 'Altogether the type of paper'- nlust consequently be controlled ferent.

making material and speed of the cylinder are varied in order to accommodate lthe constant relationship of the cylinder and Wall. A

According to this invention, instead of varying the numerous factors in order to produce a certain result or a certain kind of paper or of attempting. to mais` the various factors/accommodate themselves to the definite relationship of the cylinder mould and adjacent Wall, there isprovided a wall or walls adjacent the cylinder lo which are of such shape'as suce for general purposes and the cylinder 'ls adjustable relative to the wall or'walls. To accomplish this the cylinder mould ls movable back and forth and up and down relative to the vat and the wall or ld walls adjacent thereto so as to provide a varying space between the cylinder mould and wall.

It is possible to set the cylinder mouldto provide either a small or relatively greater space bev tween it and the adjacent wall and the said space no may be of greater width at its upper than at its lower side or it may have a constant width. Or the cylinder may be moved to provide spaces between it and adjacent walls which are similar or are relatively larger or smaller than one anas other.

Itbeing possible to vary the space between the Icylinder and wall or walls, the varying of results within wide limits is facilitated. That is to say, with a certain result vto be obtained by the do use of a certain 'paper-making material, a certain operating speed, etc. the mould may be located with reference to the adacent wall or walls to provide such a space as willoperate to the best advantage with the other factors to give a5 the desired result. For instance, to produce ya certain kind of paper with a paper-making material having certain characteristics the space between the cylinder and wall may need to have a certain form while to produce another kind im,y

of paper with the same or another type of papermaking material the space may need to be dif- The adjustability of the cylinder relative to the adjacent wall or walls therefrom makes it possible'to produce the desired results by the 4t use of paper-making material best suited for those results. The paper-making apparatus is variable to accommodate the desired results and conditions rather than conditions being varied to suit the apparatus, all to the end that not only -50 is economy 'and efficiency in operation made possible but the resul/ts are within controlv and uniform papers are produced.

The invention may be practiced in various ways butl for purposes of disclosure the following deaccompanying drawing of the invention; and

Fig. 2 is an enlarged fragmentary sectional ele-I vational view taken through one end of the apy, lar wall 24, is provided lparatus shown in Fig. 1.

Referring now to the drawing in detail the invention will beV fully described.

. In Fig. 1 which is an end elevational view of the apparatus of the invention there is shown a vat 2 in which is rotatable a cylinder mould 4 of .usual form. As in apparatus of this type, the

cylinder maybe rotated by any suitable lfmeans.

At the forward and rear ends of the vat 2 there is an end plate or end wall member such as 6 which may be of cast iron or some other suitable material. Between the end plates 6 there is a bottom wall 8 and side walls III and the said end plates and walls are suitably secured together in vat-forming relation.

A vertical wall is indicated by the end, right-hand side and bottom walls 6, 8 and III, what may be called an inlet chamber. Paper-making material may be delivered to this chamber in any desired manner so that it flows up and overwall I2, across a horizontal wall I4, and up and over the upper end I6 of a wail I8 into a space 28 between cylinder 4 and said wall I8. A'baiiie 22lmay be provided which is adjustable up and down relative to walls I2 and I8 if desired. 'I'he wall I8 is curved as shown to more or less follow the curvature of the cylinder mould and a continuation thereof, or another separate simiat the other side of the cylinder. As paper-making material is delivered into. the space in which the cylinderl rotates the fibers thereof are taken on by the cylinder mould and water passing through the foraminous surface of the cylinder passes into compartment 80 of the end plate making material passes up and over the upper end 28 of wall 24 and into chamber 32. Excess water and paper-making material are conducted from the vat in the usual way.

By curving the walls I8 and 24 substantially as shown and by providing means for moving or adjusting the cylinder up and down and back and forth in the vat relative to said walls it is possible to provide a relationship of the cylinder and wall or a Aspace therebetween ofv variable size and I'2 to provide with form. Means for moving or adjusting the cyl' Inder may be associated with each end plate 8 and since the means at each end of the vat will I be substantially similar a description of the means at one end of the vat will suffice. y

The end plate 8 at its upper side is cut away to provide an open-ended or U-shaped opening 48 and a supporting plate 42 has its side and lower edges formed to receive the plate 6 at its edges around said opening. In this way the plate 42 is slidable up and down and back and forth relative to the end plate.

A shelf part or ledge 44 extends forwardly of the supporting plate 42 and this may support a bearing or journal 44 for shaft 48 of the cylinder mould. For clearness, the bearing 44' is omitted in Fig.1. Aninner pl te 48 lies against the supporting plate 42 .and I'xverliesv an open-ended slot Il therein.`

' A'stumns box 54 provided on plate 48 receives `the shaft 48 and there may be a gland 58 assoc' lated therewith for packing the shaft and allowing rotation thereof. As previously explained.

' 6 up and.- down as well there are upper and .These latter gears or plates while excess paper-` n4whereby said cylinder the supporting plate 42 is adjustable on plate as back and forth and this may be accomplished in various ways. y

According to one embodiment ofthe invention lower screws or threaded shafts 80 and 62. 'I'he upper shaft GII is rotatable in bearings 84 associated with plate 6 and a threaded portion 86 thereof is in f threaded er1- gagement with a nut 68 which is disposed between abutments 10 associated with the plate 42. As member 60 is rotated the plate 42 is moved back and forthin one direction or the other according to the direction of rotation of said member 68.

The screw shaft 82 has threaded portions 62 which are preferably right and left hand and these threadedly engage block members 12 that are guided on or in shelves 15 associated with and extending forwardly from plate 6. By rotating menber 62 in one direction or the other the blocks 12 are moved towards or away from one another. The blocks 12 have pivoted thereto as at 14 the lower ends of links or connectors 16 the upper ends of which links are pivoted at 18 to plate 42 whereby the said plate 42 is moved up or down by the blocks 12 and screw shaft 82.

The screw shafts 60 and 62 may be rotated in any well known manner but in the form of the invention shown they carry gears 80 and 82 which mesh-with gears 84 and 86 respectively. may be fixed to the forward ends of longitudinally extending shafts 88 and 90 which carry on their other ends other gears similar to those gears 84 and 86 for operating screw shafts associated with the end plate at the other or rear end of the vat. In this way as shafts 88 and 98 are rotated the shafts 68 and 62v associated with both end plates are simultaneously rotated. y

Thus it will be seen, one shaft and associated gears are adapted to move the plate up and down so as to move the cylinder up and down, while the other shaft and its associated gears are adapted to move the cylinder back and forth.

While I have described the invention in great of, it is not desired to be limited thereto since man'y changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:

Paper making apparatus comprising in combination, a vat having end walls andspaced relatively flxed rigid longitudinal walls therebetween extending downwardly and inwardly from their upper portions, a cylinder between said walls, supporting plates rotatably supporting the cylinder slidable on the end walls. means associated with the end walls and supporting plates for moving said plates vertically relative to the end walls and means for moving said plates horizontally relative to the end walls, all adapted and arranged may be moved towards and 'away from and up and down relative to the longitudinal walls to vary the space between said cylinder and walls at the sides and bottom of the cylinder, the first named means including blocks slidably guided on the'end walls for movements towards and away from oneanother, links connected at opposite ends to said blocks and to said supporting plates and rotatable actuating members held against axial movements having screw threads formed thereon and engaged in corresponding screw threads formed in said blocks.
