PAPER-MAKIVING MACHINE.
SPECIFICATION forming part of Letters Patent N o. 703,775, dated .Tuly 1, 1902.
` Application led December 19, 1901. Serial No. 86,504.. (No model.)
T0 @ZZ 1071.071?, t may concern:
Be it known that I, GEORGE EHRHART, a citizen of the United States, and a resident of Fulton, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Paper-Making Machin es, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to the manufacture of single-ply paper of various grades-such as tissue, news, book, rope-fiber paper, and also bank-note paper containing threads of different colors.
The object of this invention is to impart to such single-plypapersuperior tensile strength for resisting strains crosswisev as well as lengthwiseof the web; and to that end the invention consists of a cylinder paper-making machine organized to form single-ply paper and provided with means for drawing pulp from the vat at one corner thereof and introducing said pulp into the vat. at the diagonally opposite corner, and thereby continuously creating diverse serpentine currents of the pulp in the vat and causing the fibers to cross each other upon the cylinder, as hereinafter more fully explained.
In the annexed drawings, Figure lis a plan view of the pulp-vat with its paper-making cylinder equipped with my invention. Fig. 2 is a vertical transverse section of the vat through the rear end thereof and including the couch-roll, and Fig. 3 is a plan view'of the vat minus the paper-making cylinder and illustrating the effect sought to be produced by my invention.
A represents the vat, which receives the diluted pulp from the pulp-screen in the usual manner. The iniiux of the pulp may be either over the side or over one end of the vat, as indicated by arrows in Fig. l of the drawings.
B denotes the revolving cylinder-mold or paper-making cylinder, which is of the usual construction, and C is the couch-roll, which takes from the cylinder B the web formed thereon in its rotation through the pulp.
To prevent the fibers from laying themselves upon the cylinder uniformly in a direction parallel with the line of motion of said cylinder, I have equipped the vat A with my invention of producing a duplex crossfibering web, which effect I preferably attain by means of an apparatus consisting of a pipe a, communicating with the vat at one corner thereof, a pipe'b, communicating with the vat at the diagonally opposite corner, and a pump P, forcing the pulp in opposite directions through said pipes, said pipes being disposed to produce transverse or crossing currents of pulp in the vat, as represented in Fig. 3 of the drawings, and thus cause the lfibers to become deposited in diverse directions upon the cylinder B. In this manner I produce single-ply paper possessing equal strength in all directions imparted to it by the bers crossing each other.
Thepump P may be located in any suitable position, and the specic arrangement of the pipes a, and b is susceptible of many modifications. Fig. l illustrates one of the arrangements of said pipes by which the object of my inventionv can be attained. As shown in said figure, the pipe a, which communicates with the vat A through one side thereof in front of the cylinder B, conducts the pulp from the vat to the pump P. The pipe b, which receives pulp from the pump, may be extended either around the exterior,
`as shown in-Fig. l, or under the bottom of the vat, asrepresented in Fig. 2, and to the opposite side of the vat at the rear of the cylinder. rIhe egress and ingress of the pulp from and to the vat being .respectively in front and rear of the cylinder produces the cross-currents of pulp indicated by arrows in Fig. 3 of the drawings.
d denotes a valve or gate connected to the pipe a for controlling the volume of pulp to be circulated through the pipes a and b.
What I claim as my invention is- In a cylinderpaper-making machine organized to forrn'single-ply paper, the combination with the vat and making-cylinder, of means for drawing pulp from the vat at one corner thereof and introducing said pulp into the vat at the diagonally opposite corner substantially as and for the purpose set forth.
