1 Claim.
This invention is a method of integrating paper tissue upon paper or other porous materials. The tissue may be blank, or it may be the vehicle for photographic or typographie impressions, but the invention is not concerned with the manner in which the impressions are obtained.
An important object of the invention is to provide means of assembling units of a typographie composition.
Another object of the invention is to afford means of assembling the units of a repetitive design.
Yet another object of the invention is to provide means of incorporating lettering in a cartographic drawing.
A further object of the invention is to aiord means of transferring a portion of a cartographie drawing to a new drawing.
Another object of the invention is to provide means of incorporating screens in a tone drawing.
Another object of the invention is to provide means of embodying repetitive images in a cinematographic drawing.A
Still another object of the invention is to provide means of combining music notations with the staves.
A further object of the invention is to provide means o f blocking out any portion of a drawing.
Another object of the invention is to afford means of providing a fresh drawing surface in a drawing to be corrected.
Further details of the invention will appear in the course of the following description, diagrammatically illustrated in the accompanying drawing.
The invention rests in the coating of paper tissue with a colloidal substance and drying the coated tissue under bi-directional restraint, thus producing an opening of the structure of the tissue.
Figure 1 represents a sheet of coated tissue I supported for drying upon a rectangular frame 2. The coating solution may consist of gelatin CTI dissolved in water, and to which may be added honey, sugar or rock candy to ensure maximum porosity in the dried coating, and glycerin or diethylene glycol to maintain pliability in-the dried tissue. The colloid gelatin is employed, not as an adhesive, but primarily because of its swelling property, its transparentizing property being incidental to the invention.
The proportions in which these ingredients are compounded may be varied to suit varied requirements. Similarly, and for the same reason, the weight and texture of the tissue may vary.
By varying coating solution and paper tissue there may be imparted to the dried material a condition ranging from clear transparency to an opacity sufcient to preclude any image underlying the tissue being photographically reproduced.
In use, the coating solution is maintained at a temperature of about F., the tissue being drawn across the surface of the solution and caused to rest upon the restraining support. When dry, the tissue is cut from the support.
The integrating action resulting from the use of this prepared tissue is shown in the greatly magnified sections, Figures 2, 3 and 4.
Figure 2 represents, in section,.a piece of prepared tissue 3, carrying in its structure the dried gelatinous coating 4, resting upon a piece of drawing board, or similar porous surface 5.
Figure 3 represents the applying of Water to the upper surface of the prepared tissue 3, by brush, sponge, damping roller, or other means, and the movement of moisture and coating 4 set up by capillary attraction.
Figure 4 represents the cessation of the moisture movement and the expanding of the gelatinous substance 4 into the structure of contiguous portions of tissue 3 and board 5.
When coated paper tissue is dried under mechanical restraint, as illustrated in Figure 1, the entire structure of the tissue will be opened so as to present free and unhindered passage to moisture. And if the coating itseli` be of a porous nature, as herenbefore set forth, the coated material resulting will offer an open avenue to the capillary attractive force inherent in porous structures.
It will be seen, then, that if paper tissue, bearing upon its face typographie or photographic images, lines, symbols or units, and prepared in the manner described, is placed upon a suitably porous surface, as shown in section in Figure 2, and wetted upon its upper or outward face capil` lary attraction w'ill cause the moisture to pass through the tissue 3 and penetrate deeply into the structure of the porous material 5 beneath, as indicated in Figure 3.
It will be evident, too, that the free passage of moisture will dissolve a portion of the coating 4 of the tissue 3 and draw it into the structure of the underlying porous material 5, and that the gelatinous colloidal substance remaining in the paper tissue 3 and .that which has been drawn into the structure of the material 5 beneath will,
by reason of its characteristic of swelling in solution and contracting on drying, constitute a powerful bonding between tissue 3 and underlying material 5.
It may be remarked that so powerful is this bonding that iine paper tissue six ten-thousandths inch in thickness is compacted by .this method .to a thickness of four and one-half tenthousandths inch, the tissue and underlying porous material becoming integrant.
Of the many advantages inherent in this invention .those most worthy of note are- Frst, that, totally unlike the mere surface adhesion resulting from the use of pastes and gums, the colloid used in the manner described provides a deeply rooted integration between two porous materials; and
Second, that, because the coated tissue is wetted upon its face, or uppermost surface, in integrating it upon paper oi' other porous materials, the position or register of any .typographie or photographic image, line, symbol or unit, with relation to any xed point or position upon the underlying material, may be held with the utmost exactness;
What I claim is:
'The method which comprises coating 'paper tissue with a gelatinous solution, effecting the opening of .the structure of the coated tissue by drying under 11i-directional restraint, placing the tissue upon a porous surface, and wetting the tissue from above.
COLIN LANDIN.
