COLORING ATTACHMENT FQR PAPER-MACHINES.
SPECIFICATION forming part of Letters Patent No. 368,803, dated August 23, 1887.
Application filed July 13, 1886. Renewed May 17,1887. Serial No. 238,508. (No model.)
To all whom it may concern:
Be it known that I, GONZALO G. ANOIRA, of Guadalajara, Mexico, have invented a new and Improved Coloring Attachment for PaperMachines, of which the following is a full, clear, and exact description.
The invention consists of various parts and details and combinations of the same, as will be' fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding partsin both the figures.
Figure l is a side elevation of part of a pa per-machine provided with my improvement; and Fig. 2 is a vertical cross-section of the same on the line a: at, Fig. 1. y
The pa oerwmachine A, of any approved construction, is provided with the usual revolving heated drying-rollers B, O, and D, of which the last is the last one on the machine. Instead of passing the web or paper E directly to the last cylinder, D, I lead the same from the cylinder 0 over the roller F, which is loosely mounted in a bracket projecting from the standards G, secured to the main frame A", which standards G carry the attachment for coloring the web or paper on one side only.
The web E passes from the roller F between the fountain or color-cylinder H and the pressure-roller I, and then around the roller J, from which it passes upward and under the tension-roller K, mounted loosely in the slotted arms G of the standards G. The web Eis then passed over the stationary roller L, and from there over the roller M and to the last dryingcylinder, D, from which it proceedsin its regular course in the usual manner until it is finished.
The web or paper E is colored on one side only when passing under the pressure-roller I and over the color-cylinder H, which latter receives a rotary motion from the shaft of the cylinder G, or from any other source. The
cylinder H has its hearings in the standards G, and rotates in the fountain N, supported by the standards G, and charged with the desired color from the reservoir 0, connected by the pipe P with the said fountain N. The press ure-roller I holds the web or paper E on the cylinder H.
It will be seen that when the paper or web E passes under the roller I, and .is pressed by the latter against the cylinder H, the under side of the paper is impregnated with the color on the cylinder H, and it readily absorbs the color supplied from the fountain N, so that the coloring of one side of the paper is thoroughly accomplished.
WVhen it is desirable to interrupt the coloring process, the operator presses the lever Q downward in the direction of the arrow 11', whereby the roller I is swung upward and permits the web E to rise out of contact with the cylinder H, and the paper is not colored.
As the roller K has a free vertical motion in the slotted standards G, it takes up any slack that may occur between the rollers M, L, J ,and F. The color-supply from the fountain N is regulated by means of the stop-cock P in the pipe P.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with a fountaincylinder, of a pressure-roller, between which and the said cylinder is passed the web to be colored, and a tension-roller to prevent the web, after being colored, from wrinkling up, substantially as shown and described.
2. The combination, with a fountain-cylinder, of a pressure-roller loosely journaled in slotted standards, and alever for throwing the said roller out of contact with the said cylinder, substantially as shown and described.
" 3. Arotating fountain-cylinder,acolor-fountain in which the said cylinder rotates, and
means for supplying the said fountain with coloring-matter, in combination with a pressure-roller journaled loosely in slotted standards, a lever connected with the said roller, and a tensionroller to prevent the web from wrinkling, substantially as shown and described.
4. The drying-cylinders Oand D, the rollers F, J L, and M, the pressure-roller I, and the tension-roller K,in combination with the fountaincylinder H, rotating in the color-fountain N, substantially as shown and described.
