PAPER MACHINE Filed July 24, 1929 5 Sheets-Sheet 5 Miami... 11, 1931 PATENT orrlca NICKOLAS J. NIKS, OF CHILLICOTEE, OHIO PAPER mamas A nmaonmea my 24, 1929. Serial No. seam.

My invention relates' to paper machines and particularly to the delivery and arrange ment of the pul on the wire at the beginning of the paper ma ring operation. l It is an object 0.1 my invention to provide a self-adjusting slice which will compensate for the inequalities of adjustment of the slice in order to provide accurate determination of the thickness of the paper. By having the flexible slice it takes care of the irregularities of adjustment and accommodates any accumulated stock.

It is a further object to so arrange such a slice with respect to the center of the breast roll carrying the wire that it is of the minimum distance from the center thereof so that both sides ofthe sheet will be made the same without streaks or mottling, as a result of perfect distribution over the wire.

It is a further object to provide a yielding seal between the wire and the stu box in order to provide an enlarged pool of paper stock so as to provide for an even distribution of stock on the wire.

It is my object to provide soft lumps from being carried on the wire into the stock and thence into the paper as it is being made by scraping from the wire all foreign materialbefore it comes in contact with the stock 0 which is to be made into paper.

It is a further object to reduce thedrainage from the paper stock to the minimum by forming this 001 and therefore being able to bring the fl exible slice close to the center of the breast roll. i

It is an additional object to rovide means of bodily moving the slice and stock box for adjustment with respect to the breast roll and to the wire.

It is a further object to provide means of arranging the fibers of the paper stock at right angles to' one another instead of parallel to one another to thereby make the strength of the resulting paper the same in all directions, to improve the uniformity of the resulting paper and improve its color, opacity and distribution of fibers in it, as heretofore the stirring and distributing mechanism in the stuff boxes consistin of screen rolls have merely delivered the fibers all arranged in longitudinal direction so that the (paper would tear in one direction more rea ily than in another.

Referring to the drawings:- I

Fig. 1 is'a side elevation partially in section of my invention;

Fig. 2 is an enlarged section showing the arrangement of the slice, stuif box, distributor and seal and the position of the apron;

Fig. 3 is a front-elevation of this apparatus with the wire in section;

Fig. 4 is a plan view;

Fig. 5 is a sectionthrough the distributor discs and shafts showing the adjusting mechanism;

Fig. 6 is a section on the line 66 of Fig. 5;

Fig. 7 is a detail side elevation on the flexible slice.

It will be understood that my invention is applicable to any type of machine, such as a Fourdrinier or Harper Fourdrinier, or with any type of slice or inlet.

Referring to the drawings in detail, 1 is a -wire passing over the breast roll 2 carried on the shaft 3. 4 indicates the usual deckel stops and 5 the wheel for guiding such stops.

6 is a support for the bottom 7 of a stufi box. This bottom is cut away at 8 to receive an apron plate 9 on which is mounted an apron comprising a rubber plate 10 having imbedded therein a spring brass plate 11. The end of this apron 10 is provided with a downwardly extending transverse rubber bar or scraper 12 which engages with the surface of the wire 1, forms a resilient seal to prevent the leakage of the stock back along the wire and also serves to scrape ofi any soft lumps that may be adhering to the wire. This rubber scraper 12 is located back beyond the center line of the breast roll 2, thus giving the opportunity of forming a relatively large pool in the space 13 for the accumulation, settling and distribution of the stock on the wire with the minimum of drainage prior to its exit beneath the flexible strip 14 which 95 constitutes that portion of the slice which is located just in front of the center line of the breast roll in spaced engagement from the wire to determine the thickness of the paper. It will be understood that this flexible strip tea 14 is mounted in a circular bar 15 that is adjustably clamped in position with a clamp 16 and bolts 17 to the slice plate 18. This slice plate is pivotally mounted at 19 on the slidable gate 20 which slides on the front 21 of the stuff box regulating the opening 22 through which the stock flows. Marginal front walls 23 divide the opening 22 and serve to hold the rubber apron in position.

The gate is regulated as to its height by the rods 20a, gears 20?) and shaft 200, the rods 24 and lever 25 adjust the clamp 25a on hinge 19.

The slice plate with the flexible strip 14 is adjusted in the usual manner by the wheel 26 operating through the worm 27, worm gears 28, adjusting wheels .29 and yokes 30 and links 31. The details of these adjustments form no part of my invention as they may be varied according to standard practice.

Such adjustments which may be made acrossa wide machine necessarily make it difficult to secure an accurate positioning of the slice with respect to the wire and to thereby maintain uniformity across the paper in thickness and composition. I secure this accommodation by utilizing the flexible strip 14 which accommodates the variations and adjustments and adjusts itself to the flow of paper stock.

The stock box has a rear wall 32 and side walls 33 which carry the distributor shaft sleeve 34. The sidewalls 33 are provided with eyes 35 that carry bolts 36 adjustably positioned in the slots 37 of the bottom 7, thereby enabling fore-and-aft adjustment bodily of the entire box and associated mech anism.

Mounted in the side walls of this box is the supportin sleeve 34 on which are carrieda number 0 are mounted by the set screw 39 on the arms 40 which rest within the screw sleeves 41 that are in turn actuated by the screws 42 from a point outside of the box as at 43. Thus the angularity of the discs 38 may be adjusted in order to determine the throw of the fibers of the stock. These discs are arranged at angles to one another in two groups so that as a result of rotation the fibers in the stock box will be delivered to the wire in crossed condition thereby giving a paper in which the fibers are substantially at right angles to one another making the paper equally strong in all directions, of uniform density, opacity and color. By the formation of relatively long passageways over the apron 10 and the settling in the pool 13 and the movement out on the wire to the minimum of draining under the flexible strip 14, while still in the maximum condition of plasticity I am enabled to deliver to-the wire a uniform, crossed fiber product uniformly distributed and resulting 1n a paper that not only has the above chardistributor discs 38. These discs acteristics but which is free from streaks or mottling and is uniform on both sides of the paper. In order to insure such a delivery I have provided on both sides of the passageway leading to the pool 13 deckel pans which form side enclosures. These pans are vertically disposed consisting of a right angle assembly' of two brass plates 44 and 45 on either side of a flexible sheet as of rubber or the like designated 46, which sheet is turned over laterally at 47 and rests upon the surface of the wire forming a seal of yielding nature. The rear end of this combination is turned at right angles to be mounted against the wall 23 which divides the exit opening 22 from the box.

Thus I provide a construction of full adj ustability, yielding accommodation in irregularities in construction and in operation.

It will be understood that I desire to comprehend Within my invention and within the scope of my claims such modifications as may be fairly comprehended within such claims and invention due to necessary modifications to adapt my invention to varying conditions of use and to varying purposes.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is: i
