PATENT MACHINE non BRESSING FIBER-s or woon PULB.

To all wZwmit maycmwe-rn Be it known that I, CHARLES LAOEY H M- TLTON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Pressing Fibers of Wood Pulp, of which the following is a specification.

My invention relates to certain improvements in machines for treating wood fiber in the manufacturing of paper.

' One object of my invention'is to provide an apparatus for opening the fiber of wood P p e a h t is mad int pap r the paper will be tough and will withstand considerable tearing strains.

A u h bj t Of the i veh ie is o provide a continuous apparatus for acting on th pap n n the e mpeny ns' d awings Fig. 1 is a longitudinal sectional iew of my improved apparatus for openingthe. fiber in the mami 'e tur of P ll t; Fig 2 is a ee tional ,view on the line 2--2,. Fig, 1; Fig. 3 is a sectional view on theline 3 3, Fig. 1; Fig. 4' is a sectional view on the line M, Fig. l; and Fig. 5 is a sectional view on the line 5-5, Fig. 1.

1 is a

cylinder having heads

2 and 3 secured thereto in any suitable manner. In the head 2 is an inlet passage connected to a supply pipe 4 having a valve 5 through which the fiber, with water, flows to the interior of the cylinder. In the head 3 is an outlet passage 6 communicating with a fixed pipe 11 in the present instance. Encircling the cylinder are rings 7, which rest upon flanged wheels 8 adapted to fixed bearings 9. The cylinder is turned by gearing which meshes with an annular rack or gear wheel 10 at the center of the cylinder, but it will be understood that other means of driving the cylinder may be resorted to without departing from, the essential fea- There are suitable stufling boxes at each end so that the cylinder is free to rotate, but the inlet pipe 4: and the outlet pipe 11 are stationary.

Within the cylinder is a series of

disks

13 and 14. The disks 13 are of a greater diameter than the disks 14- and alternate therewith, as shown in Fig. 1. Each disk has a series of holes 17 extending through it and each disk is free to roll on the bottom of the cylinder 1. The disk 15 at the feed end of the cylinder has a series of ribs 16,

wh ch t nd he hit he m ter a es. i s sharged hea th nl p p T k 3 has a series of radial grooves and, in some nstance edtlitie le e ee at e i f the radial grooves as shown in Fig. 4, while the disks 14 have a serie of curved pa ages 19 rmed he e n, h eh a t crape he ma er a m the bottom of the cylinder carry it to the holes 17 in the disks. The radial gtQQvcs 18 act to discharge th mat r elftewe d th per phery of. th yl nde Tllus it will be seen that the pulp, as it enters the cylinder, is carried not Only u der he s eral d sk ut e e th o g h disks and through the space between the d ks s0 that the fibers ar p ess a raratedvbetween the disks, as well as between the disks and the cylinder, the material eve ual y flowing out th g the ieeherse passage 6-1 Th di k 5' ha i s 1 6?, which are so, designed as to lift the material and discharge it through the outlet.

I pr ferably t rm, ee he d wi e P jection 20, which extends into'the cylinder and tends to hold the disks in proper position, insuring the movement of thematerial within the cylinder, the water in the fiber being non-compressible, the pressure will cause the fiber to open and separate. Paper made from pulp treated in this manner is exceedingly tough, as the fibers retain their strength.

In the above described machine, the pulp is fed continuously through the machine so that it can be part of a system in which the flow. of the material is continuous. Heretofore, the practice has been to reduce the pulp in batches and these batches had to be removed before the pulp could be pressed.

I claim:

1. The combination in an apparatus for pressing the fibers of wood pulp in the manufacture of paper, of a cylinder; means for rotating the cylinder, said cylinder having an inlet and an outlet; and a series of disks arranged to turn freely within the cylinder as the cylinder is rotated so as to press the fibers of pulp passing through the cylinder.

2. The combination of a cylinder; means for rotating the cylinder; means for feeding pulp into one end of the cylinder and discharging it from the opposite end thereof; and a series of disks located in the cylinder, each disk having perforations so that part of the material will pass between the disks and the cylinder, while the other part of the material will pass through the perforations.

3. The combination of a cylinder; means for rotating the cylinder; means for feeding pulp into one end of the cylinder and dis-' ingthe fibers of pulp in the manufacture of paper, of a cylinder having a feed opening at one end and a discharge opening at the opposite end; means for supporting the cylinder; means for rotating the cylinder; and

a series of disks located within the cylinder,

said disks being arranged side by side, each disk having perforations therein, each alternate disk having curved channels leading to the perforations for scooping up the material and directing it to the perforations in the disks, the other disks having radial passages leading from the perforations to discharge the material towards the periphery of the disks, insuring the constant flow of material through the cylinder and through the space between the disks.

The combination in apparatus for pressing the fibers of wood pulp in the manufacture of paper, of means for supporting the cylinder and means for rotating the same a feed opening at one end of the cylinder; a

discharge opening at the opposite end thereof; and a series of disks located side by side within the cylinder, the alternate disks being of one diameter and the other disks being of another diameter, each disk having a series of perforations therein.

7. The combination in apparatus for pressing the fibers of wood pulp in the manufacture of paper, of means for supporting the cylinder and means for rotating the same; a feed opening at one end of the cylinder and a discharge opening at the opposite end thereof, and a series of disks located side by side within the cylinder, the alternate disks being of one diameter and the other disks being of another diameter, each disk having a series of perforations therein,'the disks at the feed end having ribstending to distribute the material as it is fed into the cylinder, and the end disk at the discharge end having ribs tending to lift the material towards the outlet.
