I-IO'W'ARD PARKER, OF NASHUA, NEW HAMPSHIRE, ASSIGNOR TO IMPROVED PAPER MACHINERY COMPANY, OF NASI-IUA, NEW HAMPSHIRE, A CORPORATION OF MAINE.

MULTIPLE-GOLOR PAPER AND PULP MACHINE.

To all whom it may concern:

Be it known that I, I-IowARo PARKER, a citizen of the United States, and a resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Multiple-Color Paper and Pulp Machines, of which the following is a specification.

This invention relates to machinery for handling pulp or paper stock of different colors, keeping each color separate from the other.

The invention is illustrated in connection with a machine known as a Save-all, namely, in which the waste water from a paper machine is treated in order to reclaim A- description of the invention as utilized in this machine shows clearly how it can be used in other ways. p

In the drawingsFigure 1 is a perspective view of the tank. Fig. 2 is a perspective View of the cylinder mold. Fig. 3 is a central horizontal section of the machine. Fig. 4 is a detail perspective view showing the division plate on the doctor Referring to the drawings a denotes the tank in which a cylinder mold b is rotatably mounted. This cylinder mold is provided with a foraminous shell 0.

Arranged transversely of the tank is a partition 03 dividing it into separate compartments, the partition being cut away to fit closely about the cylinder mold.

A packing-ring 10 of brass or other suitable material is arranged circumferentially about the exterior of the cylinder mold opposite the partition d and is secured in place by screws or bolts which pass through the mold shell and engage a fastening-ring 11 secured to the interior of the shell. The edge of the partition 0'! is recessed as at e and a strip of packing material f is wedged in between the packing-ring 10 and the partition, leaving the mold free to rotate but forming a liquid-tight joint.

Within the cylinder mold and opposite the partition in the tank is a division-plate 20 attached along its outer edge to the fas tening-ring 11 and forming in connection with oppositely inclined bottom-plates 22- 24, which are secured to the inner edge of said plate, separate compartments in said mold. Preferably these compartments are Specification of Letters Patent.

divided into longitudinal chambers by radial partitions 26 extending from the shaft to the shell in order that a suction device may be utilized at the ends of the mold opposite the submerged chambers to assist in collecting the pulp on the exterior of the mold and draw the water through the shell into the interior of the mold, from whence it is drawn off through the ends of the mold and the end walls of the tank. I also utilize means located against the ends of the mold to introduce air under pressure into the chambers just before they reach the doctor 30, in order to assist in dislodging and removing the collected pulp from the exterior surface of the mold. The edge of the doctor is recessed as at 32 to fit over the packing-ring 10, leaving the edge of the doctor fitting closely against the surface of the mold. The doctor is provided with an upstanding plate 34 which divides it into two parts corresponding to the two compartments in the tank and prevents the intermingling of the pulp collected from the compartments of the tank.

It is obvious that the details of construction herein described may be altered without departing from the spirit of my invention. It is also apparent that the machine may be modified, for instance as by increasing the number of sections within the mold and correspondingly increasing the number of compartments within the tank.

By the invention herein illustrated and described a machine of great simplicity and efliciency is produced.

I claim:

1. In a machine of the character described the combination with a tank, a partition arranged transversely therein to divide the tank into compartments, a cylinder mold rotatably mounted in the tank and extending through said partition, a liquid-tight packing between said mold and partition, and an outlet from the ends of said mold.

2. In a machine of the character described the combination with a tank, a partition arranged transversely therein to form separate compartments within the tank,'a cylinder mold rotatably mounted in said tank and extending through said partition, a division-plate arranged within said mold transversely thereof to form separate compartments, a foraminous shell on said mold,

a packing strip secured to the exterior of said shell circumferentially about said mold and directly over said division-plate, a liquid-tight packing between said partition and the packing strip on said mold.

In a machine of the character described the combination with a tank, a partition arranged transversely therein to form separate compartments within the tank, a cylinder mold rotatably mounted in said tank and extending through said partition, a division-plate arranged within said mold transversely thereof to form separate compartments, a foraminous shell on said mold, a packing strip secured to the exterior of said shell circumferentially about said mold and directly over said divisionplate, a liquid-tight packing between said partition and the packing strip on said mold, and inclined bottom-plates for the compartments of said mold.

t. In a machine of the character described a tank, a partition arranged transversely thereof forming compartments within said tank, a cylinder mold rotatably mounted in said tank andextending through said partition, a division-plate within said mold in alinement with said partition, a liquidtight packing between the shell of said cylinder mold and said partition, and an outlet from the ends of said cylinder mold.

5. In a machine of the character described the combination with a tank and a partition arranged transversely therein to divide said tank into compartments, of a cylinder mold rotatably mounted in said tank and extending through said partition, a division-plate within said cylinder mold and arranged transversely thereof to divide said mold into compartments, radial plates arranged longitudinally within said mold compartments to form chambers, bot-tomplates for said compartments inclined toward the ends of said mold, a liquid-tight packing between the shell of said mold and said partition, and suction and blowing apparatus arranged in operative relation with the ends of said mold, substantially as described.

6. In a machine of the character described a tank divided into compartments, a cylinder mold rotatably mounted in said tank and divided into compartments, each compartment of said cylinder mold being located within a compartment of said tank, liquid-tight packings between the cylinder mold and the walls of said tank compartments, and a foraminous shell on said cylinder mold.

7. In a machine of the character described the combination with the tank and a partition arranged transversely therein to divide said tank into compartments, a cylinder mold rotatably mounted in said tank and extending through said partition, a division-plate arranged within said cylinder mold transversely thereof to divide said mold into compartments, a packing-ring secured circumferentially to the exterior of said mold opposite said partition, and a packing strip located in a recess in the edge of said partition and bearing against said packing ring to form a liquid-tight joint between the compartments of said tank.

8. In a machine of the character described a tank and apartition arranged transversely therein to divide it into compartments, a cylinder mold rotatably mounted in said tank and extending through said partition, an annular division-plate secured along its outer edge to the interior of the shell of said mold, oppositely inclined bottom-plates secured at their ends to the inner edge of said division-plate and extending toward the ends of said mold, a packing-ring secured to the exterior of said mold over said division plate, and a packing strip between the edge of said partition and said packingring.
