SUCTION APPARATUS FOR PAPER -MILLS.

SPECIFICATION forming part of Letters Patent No. 478,290,dated July 5, 1892. Application filed December 19, 1891- Serial No.'415,5'79. (No model.)

To 00% whom it may concern:

Be it known that we, EPHRAIM $ANDERSON,

and FRANK O. BASE, citizens of the United- States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Suction Apparatus for Paper-Mills, of which the following, with the accompanying drawings, is a specification.

Our invention relates to apparatus for removing water from pulp and from the fiber of paper as it is carried by the wire over the rolls in a paper-mill.

The object of our invention is a mechanism, which is simple in construction and efiective in operation, to remove water from pulp and paper while the same is being carried over the wire; and it consists in the construction and combination of parts, as shown in the drawings, described herein, and defined in the claims.

In the drawings, Figure 1 is a side elevation in general outline,illustrati ng the application of our invention. Fig. 2 is an enlarged vertical section of our device on the line 00 a: of Fig. 1. Fig. 3 is an enlarged elevation of our suction device and the pump. Fig. at isa front end view of the suction device with the face-plate removed. Fig. 5 is an opposite end view of the suction device, showing the pipes that make connection with the endless series of suction-boxes. Fig. 6 is an outside end view of the suction device and illustrates the outside face-plate with gear attachment. Fig.

7 is an enlarged broken vertical sectional View illustrating the means employed to insureatight closing of the radial holes through the rotating shell. Fig. 8 is an enlarged longitudinal section illustrating the arrangement of the suction-regulator and suctionpipe with reference to each other. Fig. 9 is an interior view in cross-section of the ring of the rotating shell; and Fig. 10 is an enlarged detail view of thesuction-boxes, the length of the boxes being contracted with reference to their width.

In the drawings, Fig. 1 shows in outline, in elevation, the wire W and the rolls R, over which the wire travels. The endless series of boxes B travel over rolls R. The suctionregulator stands outside of a vertical line with the endless series of boxes, and the suctionregulator pipes extend in between the laps of the endless series of boxes to make connection therewith. The-relative location of the invention to the wire and rolls of a paper-mill is illustrated by Figs. 1 and 2.

The suction-boxes B are preferably constructed of rubber and consist of open-top boxes the width of the wire W and rolls R and have an opening bin the bottom at their center. The end pieces B consist of enclless pieces of rubber grooved part way through their depth, into which grooves fit the partitions B This construction allows the boxes to pass easily over the rolls R by opening'a little as the boxes round the rollers, and still they close tightly together when on a straight line as they are immediately under the wire W.

Inside the end pieces B are adjustable heads 13"", capable of movement longitudinallyin the boxes. Arod b extends through the boxes, passing through the end pieces B" and the movable heads 13". Said rods b have a head b" upon the outside of the box or have other means provided for turning the same. Within the end pieces B" the rods 1) are smooth; but inside said end pieces the rods are threaded nearly to the middle of the rods, one end having a right-hand thread and the opposite end a left-hand thread. The movable heads 13"" are also threaded interiorly, so that when the rods b are turned the heads B may be thrown to or from the .middle of the boxes, and thus adapt them to use when running paper of different widths through the mill. The rolls R, over which the endless series of suction-boxes travel, are such as are in common use in paper-mills, and need no description.

Our suction -regulator consists of a shell formed of a ring A (through which are radial openings at and nipples a on the periphery of said ring for making pipe connections therewith) and face-plates A and A". Said faceplates are secured to the ring A by means of bolts a", as illustrated. A suction-pipe C, which also serves as an axle for the suctionregulator shell, passes through the center of said shell, and the-shell rotates thereon. To make the shell air-tight around said suctionpipe 0, we employ suitable stuffing-boxes C. To the face-plate A we attach a gear A to provide a means of driving the suction-regulator shell. lVithin said shell is a stationary cylindrical block D.

Below the suction-pipe 0, between it and the cylindrical block D, we interpose springs E or rubbers to force the said block D tightly against the inner face of the ring A of the shell to insure a tight closing of the radial openings a. In the top of said block D an opening D is made, preferably wide enough to leave open not more than three of the radial openings a. An opening 0 is made in the top of the suction-pipe G to communicate with the opening D. Said suction-pipe is open through its length from said opening 0 to the suction-pump P, and it is closed outside said opening 0 to the opposite direction, as seen at c.

To the nipples a are attached pipes B, which bend over the edge of the shell toward the shaft 0, runalong the shaft 0 to a point under the middle of the suction-boxes B, and then turn outwardly, so as to make connection with the holes I) in said suction-boxes. The radial part B of the said pipes is preterably made of rubber, so that they will be yielding and that three of them may be in connection atall times with the suction-boxes B. Instead of using rubber pipes for this purpose, metal pipes with spring-operated sliding sleeves may be used. These pipes 13 must be so arranged as to register with the openings 1) in the bottoms of the boxes B. To keep said pipes B and their radial projections B in proper position, we use a spider F of any suitable construction.

G. G are brackets to support the suctionpipe 0 and the suction-regulator, and H H are brackets to support the rolls R R.

The wire W, the endless series of boxes, and: the suction-regulator are each driven by separate power connections.

The operation of our apparatnswill be readily understood from the drawings and the description already given. The wire XV carries the paper or pulp over the boxes B, and said boxes travel with said wire. In the travel of the boxes B the radial pipes B make connection with the opening I) in the suction-boxes, and the pump P creates a vacuum in the opening D of the suction-regulator, which draws the water from the paper or pulp over the boxes B as they come into connection, and the water is carried out through the suction-pipe 0. As the shell of the suction-regulator turns the difierent pipes B are brought to register with the boxes B, and the cylindrical block D keeps closed all the radial openings a, except those that are in connection with said boxes B.

The machine will work for different widths of paper by adjusting the movable heads 13" of the boxes B, as hereinbefore described.

Our invention may take on various modifications in details of construction, and we do not therefore limit ourselves to the exact form and arrangement of parts, as shown and described.

That we claim as our invention, and desire to secure by Letters Patent, is.
