To all whom it may concern.'

Be it known that CARL EICHHORN, a citizen of Nimwegen', Holland, and CLARENCE W. CAMPBELL, a citizen of the United States, each residing at Dexter, in the County of Jefferson and State of New York,`have invented certain new and useful Improvements in Paper Making Machines land Processes of Making Paper, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to an improved paper making machine and process of making pa er and we do declare that the following is a fiill, clear, concise and exact description thereof, sufficient to enable one skilled in the art to make and use the same,reference being had to the accompanying drawings in which like letters and numerals refer to like parts throughout.

In the drawings weillustrate our invention of a machine in a single application thereof, without limiting ourselves to the details and particulars shown by the use of which the method invented is to be practiced.

Our invention is applicable particularly to a machine which comprises a screen onto which the stock is fed through suitable open ings, and in the operation of which machine the water is passed ofi` and the paper stock is retained The purpose of our invention is to make a more perfect weaving of the fibers which make up the paper, and to regulate the feed of the paper stock to the machine, to control its weight, evenness, appearance etc., and to provide for different feeds to accomplish such results. f

lt will be apparent from the description of our device that a multitude of effects can be obtained,as for instance, producing a sheet of d ifl'erentulistinct color on each side. We also show how different coloring materials or fluids can be admitted atproper places, and means by which the feed of the paper stock orother materials or fluidslean be put under pressure. l Y,

Other features of our device will be apparent to those familiarv with the art, together with various modifications of our device and modified uses of the same, whiclirwe do not Aattempt to state in full.

'In the drawings Figure l is a side viewof a -well known machine, showing ourinveiitidn applied thereto; Fig. 2 is a plan view of the same with the cover of the feed boxes removed, and Fig. 3 is a longitudinal sectional view.

As stated, our device is applied to a machine of familiar construction which is mounted on a solid base-not shown, but which supports the standards A on which rests the bed of the machine A. On the bed of the machine is supported at one end the flow box A, which outlets into the sluice formed with the sides B secured to. the flow boxes A. The bottom of the sluiceway is formed of a flexible apron indicated by B, but not fully shown, one end being secured to lthe flow box A and the other resting on the endless screen C which is carried on the drum or breast roll C (there being a suitable support lat the other end), which drum or roll is carried by pulley c to pass the screenI in the direction indicated by the arrow in Fig. 1. The screen passes on the rolls C which extends from one side of the machine to the other and are supported in journals on the bar 0 mounted on the standards.

At the end of the sluiceway is gate D which bears on the end of each side piece B, but which is screw mounted to slide up and down IGNORS TO by means of the wheels D whereby the feed of the paper stock onto the screen may be regulated. Of course, it will be understood that the paper stock is let into the How box Al whence it passes onto the apron under the gate onto the screen.

Across the screen we mount a secondary feed or flow box E. From the flow box A to the flow box E extend feed pipes E through which the stock is fed from the former to the latter, the pipes being connected to the box E at its ends. At the end near the box E each pipe is provided with a stuing bot' E so that the flow box E can-be swung on the pipes and held in a given posiy tion.

Each pipe section, which is connected to the flow box E has an independent support E" on the bed-plate A. vOther suitable means may be employed for holding the flow box E in a given position on its pivotal mounting, but such means, if not formed as a part of the stuffing box, can be devised and applied by any mechanic. The lower part of this feed box is shown in section inFig. 3; it has a tight fit ing top 1 and side pieces 2 and`3 which after extending downwardlyaA clearly indicated in that figure.

suitable distance turn toward each other, as It will be seen that the side 2 projects downwardly nearly to the screen, and the side 3 if extend.- ed would meet the surface of the side 2. .A

long zgitudinal opening, the length of the box,

is provided which normally thrusts the pulp material outwardl from the-box in a direction opposite to t at'in which the screen is traveling. It is well known that the'paper stock 'contains a large number of very irinute fibers which naturally in the revolution of the screen take a certain direction, and

f when the manufacture of the paper is finished'the' fact that these fibers are substanarallel to each other causes a weaknesso the paper under strain'across the line of 'the fibers. A 'prime purpose of the' method shown inthe invention and of the means `by which we ractice it is to cure this,` which we accomplis by forcing a secondary feed from the box E onto the screen against the direction in which the fibers lie and are traveling, the result of which upsets their regularity .and dispersas them at angles, orbends them so that they naturally cross and' weave into 'each other and engage each other,- wher'eb the paper is -made of neater strengt I. 1 Ist-will be apparent also t at byy means of this feed Abox and `its adjustment.

'- in various Ways We' can regulate the force `rial that is fed into the 5 regulate the amount of the feed, we provide along the edge 3 a sliding strip 4 which isengaged bythe screwthreaded stems 5 which passesthrou h lugs 6, and by the ad'ustment of whic screw-thread the Width oi thev openingv between the sides 2 and 3 can' be regulated. We have spoken oi pressure being'applied to this feed, and we indicate at 7 a pipe for sucha purpose, which may be usedv to transmit atmospheric, steam or other` ypressure to the contents voffthe fiow box'.

he pressure applied to the contents of the feeds, as through pipes 7 and 13, is distinct ',from'thepressure consequent on the fall of "force as distinct from the natural fall.

also provide in the fiow box a shaft 8, with material from the source .of supply, `Aand by -the term pressure we referto such artificial We beaters 9- thereon, -and which is revolved by means of sprocket chain 10, or otherwise suitas will be indicated later on.

ab?, t the oint where the box E is located they fluid is held onto the screen by the welllinown deckle straps i? which ass over the drum or wheels il", the lower and resting onftheA bars I arid l.

screen adjacent to its edges and traveling with it. The deckle drum, or wheels, is supported on standard F" from which extends arms 8 to support the sides B of' the sluiceway.

We provide further Athe feed G which may be used as here indicated to feed. powdered coloring material, 01'- which can be vused for dispersing of coloring or other iiuids onto the stock` as it passes thereunder, and which, therefore, cooperates with the feed box E to produce the desired combination of effects by means of liquid or other substances, according to the product which is desired, and may be fed in a similar way. lt has the .body 11f and the close fitting top 12 with opening 13 whereby ressure can be applied 'to thel contents. T e body 11 curves downwardand up onto the other side, but is provided with a longitudinal opening 14 from which depends a wall member 15 nearly to the surface ofthe screen. Gplposite this Wall member is pivoted a wal member 16 and spring 17 is mounted to bear against the wallvand hold itv in place, but the play of which may be regulated 'by screw member 18. Within this eompertinent G is a shaft 9 with spoon arms shown as G .which may be revolved in either' direction to drive the contents against, the

`Walll,whence it drops downward'bctwcen the walls and is fed onto the paper Stockaccording to the revolution of the spoons and 4the size of the opening and the disposition of the box Gr. This box is supported in two ways. To it we secure'thebrackets l-l which are in two members overlapping and provided with thumb-screw in slots whereby the ends lof the box G can be moved in or out, the sides being formed of overlapping members adapted to slide on each other so that the box can be telescoped longitudinally. Through the brackets H are screw-bolts h', by the adjustment of which 'the box ycan be turned'4 axially. With this mounting the box partakes ofthe vibration of the machines, but we desire at times to have it fixed so as not to take anyof the vibration, and for that purpose we provide such a device as. is shown by the standard I which is fixed tothe solid base.

of .the -machine and which has connected a slot in l so that the box G cany be raised or lowered, or turned in a given direction. At the upper end of the bar'l lwe have bolt 'i' passing through a slot in I so that the standards l andi can be freed fromclose engagement with the brackets H, or the bolts /t can be raised tothrow the entire weight onto the Box E canbe mounted also, in this way.

Power is applied to the device, for -instance, through pulley c which turns the breast roll C. The power .is transmitted by the belt to a .pulley on the deckle roll shaft from whence it vpasses through theI bolts e .thereto the arm I by bolt i fastened through and f to the How box E and the box G. respectively by pulleys or a series of pulleys by which the rate of speed maybe suitably fixed or altered.

In short we have produced a paper making machine and, method of paper making, yin

.which the product 'i affected by means of a v secondary leed in a given direction., and With a given torce natural or under pressure, by-

which stock or water can be added to the stock on the screen to accomplish the purpose which we have indicated in a general way without limitation, and a further feeding device for contrilmting paper stock or coloring material or other' substance under pressure or otherwise and in a chosen direction to further modify the construction and appearance ofthe-product of the mach ine.

We have merely indicatedI one application of our invention but do not attempt to specify all possible uses of the same which will be apparent to one skilled inv the art. i

Having described our invention, what we claim as new' and desire to secure by Letters.
