ADJUSTABLE DECKLE FOR WET-CYLINDERPAPER-MACHINES.

To all whom it may concern: 3

Be it known that I, ALTON STAMETs, a citizen of the United States, and a resident of Gloucester City, county of Camden, State of New Jersey, have invented certain Improvements in Adjustable Deckles for Wet- Cylinder Paper-Machines, of which the following is a specification.

One object of my invention is to improve the construction of cylinder paper machines,

' by making the deckles laterally adjustable :so as to regulate the width of'th'e sheets of paper formed upon the cylinder. A further object of the invention is to provide means for making a tight joint between the deckle and the cylinder so as to prevent the escape of the pulp at the space in the :side beyond the deckle.

A still further object of the invention is to provide means for simultaneously adjusting the deckles of paper machines as fully described hereinafter, reference being had to the accompanying drawings, 1n wh ch Figure 1, is a side view, partly in section,

showing a set of three cylinders used in connection-with paper making machines; Fig. 2, is a planview' of one end of a series of paper making machines; Fig. 3, is a sectional plan view of a part of one of'the machines; Fig. 4, is a detached perspective view'of the deckle frame; Fig. 5, is a perspective View of one of the deckle bands; Fig. 6, is a perspective View of the U-shaped lining; Fig. 7 is a view of a modification of a the means for adjusting the, deckle frames; and Fig. 8, 1s a vlew showlng guides for the deckle band.

I have'illustrated a set of three machines located in line one'with'another, so that a three-ply sheet of paper can be formed by having a screen 3 thereon. The cylinder is mounted on a transverse shaft 4, and any suitable means is provided for rotating this shaft. The vat is supplied. with the paper' stock and a suction device is provided for creating a suction within the cylinder so that, as the cylinder rotates, a certain amount of the stock is drawn up the screen.

'stock can pass beyond the frames 5.

"stock from the screen as the cylinder rotates forming thesheet. In order to regulate the Specification of Letters Patent. l t t d N 23 1915; Application filed July 22, 1914. Serial No. 852,441.

width of the'sheet a deckle is located on the side of the cylinder. Extending across each cylinder, above the liquid line, is a felt and this roll. A spray pipe is used to spray 'above thisfelt is the ordinary couch roll. Q The paper 1s drawn from the cylinder under water on the cylinder so. as to. keep it clean after the paper has been removed. All of the above described'mechanism is common to this type of machine and the primary object of my invention isto improve the form ing the deckles simultaneously. 7

Located in each end of the vat 1 is a U- shaped lining 1, preferably of. brass: or

' bronze. The liningis flanged and the flanges of deckle and to provide means for adjusta V grooved, as at 7, to receive a segmental strip of felt 8, or other suitable material. The felt extends above the surface of the liquid containing the paper stock;

Mounted on the upper end of each frame 5 are two rollers 9 over which passes the endless deckle band 11. This band extends between the wire screen 3 and the felt 8. The joint between these two is such that no paper The other portion of the band hangs freely with- .in the vat, as shown in Fig. 1. Anti-friction rolls 12 are located at intervals so as to guide this run of the band. By this construction the pulp is retained in the space between-the two deckle frames.

Inorder to move the deckle frames in. unison toward and from each other, so as to increase thewidth of the paper'being formed on the cylinders 2, I mountthree screw rods 13 in bearings 15 and extend these through stuffing boxes 14 secured to the outside of the vats, and on the deckle frame 5 are nuts 16 through which the screws eXtend,so that, on turning the screws in unison, the deckle frame will be moved toward-and from the 20. This shaft extends along the full length of the series of vats, so that, on turning the shaft 19 by the hand wheel :21, all 7 the sprocket wheels will be turned in unison on that side of the several vats and, asthere is a duplicate of thismechanism on the opposite side of the vat, the deckle frames at each,

side are independently adjusted.

In place of the construction illustrated in Figs. 1 and 2, I may use the construction,

illustrated in Fig. 7, in which the screw 13" is secured to thedeckle frame 5 and passes through a stuffing box 1 1 in the casing, and

the sprocket Wheel 17? is in the form of a nut and turns on the screw. 7

15 is a bracket to hold the sprocket wheel in position. On turning the sprocket'wheel 17 the deckle frame 5 will be moved in either direction. j e I In Fig. 8, I have shown a flange 5 on the deckle frame to hold the deckle band on the roller 9, if it is found desirable. The roller may have a certain amount of side play on its bearing to allow the band to run free.

1. The combination in a cylinder paper machine, of a vat; a cylinder mounted therein and having a screen; a deckle frame,

partly inclosing the cylinder and fitting the vat forming a partition; an endless deckle band" carried by the frame, one portion of the band bearing against the cylinder; and yielding meanson the frame bearing against the band so as to make a tight joint between the frame and the band to prevent the paper stock from passing beyond the deckle frame.

2. The combination of a vat; a cylinder mounted therein; a screen on the cylinder; a deckle frame fitting the side walls of the V vat at or about the liquid line and having a segmental groove; a felt mounted in the groove extending above the liquid line; with anendless belt supported by the frame, one portion of the belt extending between the cylinder and the segmental felt, the other portion of the belt being-out of contact with the cylinder.

3. The combination of a vat; a pylinder mounted in the vat; a deckle frame located in the cylinder, the ends of the deckle frame resting against the sides of the vat; two

rollers mounted in the upper portion of the deckle frame, one at each side of the cyl inder; an endless loand arranged to pass around both rollers and looped, the inner loop bearing against the cylinder, the outer loop being free of the cylinder; and a seg-' mental strip of felt carried by the frame and bearing against the inner loop of the band.

4:. The combination of a vat; two fixed U- shaped linings, one located at each end of the vat; a cylinder mounted in the vat; a deckle frame mounted in each end ofthe vat and directly encircling the cylinder; each deckle "frame fitting the lining; an endless band carried by each deckle frame, the bands being looped'so as to pass under the cylinder,

6. The combination of a vat; a cylinder mounted therein; twodeckle frames within the vat extending from oneside thereof to the other and partly encircling the cylinder; an endless band under the c linder and carried by the deckle frame and, fitting between the frame and the cylinder so as to make a tight oint; nuts on theframe; screwshafts carried by the vat and extending through the nuts, said screw shafts beinggeared to t gether; a set of screw shafts for each deckle frame one set bein located on one side of the vat and the other on the opposite side;

and means for adjusting each set in unison so as to increase or diminish the width of paper formed on the cylinder.

7. The combination of a series of vats arranged in line one with another; a cylinder in each vat; a deckle frame at each end of each vat and partly encircling the cylinder; deckle bands carried by the said frames; means for traversing the deckle frames in each vat toward and from each other; and mechanism for actuating said last mene tioncd means so that all of the deckle frames on one side of the vat will travel inunison.
