YORK.

Application filed August 4, 1922. SeriaLRo. 579,752.-
To all whom it may concern:
Be it known that I, WINFIELD P. PEM
nnonn, a citizen of the United States, and
resident of Rochester, in the county of Monroe and State of New York, have invented.
. classes, namely, those which produce a substantially non-permanent record and are employed. for pencil carbons and those which produce a substantially permanent record and are employed most generally for making copies on typewriting machines.
Those-carbon sheets of the first class employ a highsaturable carrier or paper with in a heated condition for an extremely penetrating color or coating, due to the use of little or no insoluble coloring matters in the coating and to the use ofbut a small amount of wax. The other class of carbon sheets employsa high grade of paper stock mostgenerally linen tissue as a carrier, and a color-coating high in wax-content and low insoluble color content.
In manufacturing the second class of carbon sheets,'it is customary to employ a coat ing containing a wax with an insoluble color, suchf for instance, as lamp black. This is ap liedto one 'face of the carrier while in a of. condition, and after properly being spread over the carrier, is immediately subjected to a cooling action for the reason that if the wax in the coating is maintained too long a period of time, the most (1 sirable carbon paper is not obtained. Owigrg to the short period of time that-the col coating is'heated, the color coating does not have sufiicient time to penetrate the carrier, so that the carbon sheet produced has the color coating adhering substantially only to .the face thereon. Such acarbon sheet has two disadvantages; first, the sheet is substantially a'stencil and upon each use thereof a great, deal of the coating comes ofi, so that the life of the carbon sheet is comparativel limited; and second, the coating has a di erent coeflicient of expansion from that of the carthe stored goods.
the application of the. two coatings, the
from the pulp after the cha over machines now possible to arrange the sheet in a flat condi tion and interfering With the handling of the sheets in use; The life of such carbon sheets may be slightly increased by ageing them, that is, permitting them to stand for .a considerable length of time until the wax containing coating penetrates to a slight degree the carrier sheet. This, however, requires that the manufacturer shall maintain a space to store the goods, and at the same time, have a money investment tied up in According to this invention a carbon sheet of the second class is obtained which is substantially non-stenci'lling, due to the fact-that the coloring matter penetrates the paper or other carrier, and which also is non-curling because the coloring coating is so intimately combined with the paper or other carrier sheet that the latter has substantially a uniform co-eflicient of expansion throughout. y
u The drawing shows in section. a carbon sheet with three clearly defined layers,.but it must be understood that this is only for the purpose of illustrating the sequence of final production being a homogeneous structure in whichno definite layers are present.
.In carrying out this invention, a carrier sheet 1 is employed which has a low satue rabili but-which preferably has a higher satura ility than the carrier sheets usually employed in carbon sheets of this class. A
carrier sheet, which may be employed is made from a pulp composed largely of linen-mixed with a small percentage 0t precipitate of chalk, so that the pa or produced coating of the different fibers has a slight saturability.
A 'color coating 2, which may be employed, embodies an insoluble color such as lamp black, a wax, oleic acid and some one or more of the basic aniline oil soluble colors'. The color coating is applied to-the carrier, preferably one whose saturable properties have been increased in a manner hereinbefore mentioned, by a coating mas chine which runs at a high rate of speed, the
a common custom. The speed of the coat- [in 'machine may be materially increased in use. Afte the first coating, either on the same machine or on another machine, immediately orafter the coating has been permitted to partially penetrate the carrier sheet, the carbonsheetis. again heated and immediately cooled, thus causing-the wax and oils cf the original coating to still further penetrate the carrier sheet andcarry the coating therein. -During such reheating a second color coating 3, may be applied. This rerunnin of the carbon sheet either with or withou additional coatings may be continued any desired number of times until the degree of saturation of the carrier sheet desired is obtained. The second or any one or more of the. coating after the first coating may not contain the soluble colors but may contain an insolu-/ ble color. From the foregoing it will be seen that there has been provided a new method .of making carbon paper whereby there is ob-' tained a carbon paper in which the color coating is substantially homogeneous with the carrier sheet, so'that the stencilling properties of the sheet are reduced to a minimum, thus increasing the life of the carbon s heet.- At the same time, a. sheet is obtained which is non-curling due to the fact that the color coating penetrates the carrier sheet and gives to the sheet, as whole, a substantially equal coefficient of expansion. The sheet also has a heavier body and this naturally tends to stop the wrinkling and the consequent cracking of the coating. The carbon sheet produces a larger number of copies, as only a small portion of the coating is removed by each use. In fact the sheet may be employed until it is substantially worn out through the use thereof by the typewriting machine. This is diiierent from the ordinary carbon whereupon the first use siibstantially all of the coating is removed from the surface at the printing point.-
. What I claim as my invention and desire to secure by Letters Patent is:
1. A method of making carbon paper which consists in applying, to a slightly saturable carrier sheet, a heated wax-contain color coating with penetrating proper- .tles, immediately" cooling the waxcontaming color-coating, and" thereafter reheating the coated sheet and immediately cooling the same to cause the color-coating to still further penetrate the carrier'sheet.
2. A method of making carbon sheets which consists in applying, to a slightly saturable carrier sheet, a heated wax-contain- .ing color-coating with penetrating properties, immediately cooling the -wax-containing color-coating, thereafter applying to the coated side ofsaid sheet'another heated Wax-containing. coating, heating the coated sheet to cause the first coating to still further penetratethe carrier sheet and immediately cooling said sheet.
3. The method of'inaking carbon paper which consists in applyinga heated wax- --containing color-coating to the sheet, im-
mediately cooling said coating, and thereafter reheating and 1mmed1ately" cooling the coatmga number of times to obtain a carbon sheet saturated'by the coating to a desired degree. y 7
4. A method of lmak ingcarbon sheets which consists in providing a saturable carrier. sheet, coatingsaid sheet with a hot wax-containing soluble color-coating, immediately cooling said coating, and thereafter reheat-ing and immediately cooling the sheetto cause the color-coating to penetrate the sheet. v
A method of making carbon sheets which consists in providing a saturable carrier sheet, coating said sheet with a hot waxcontaining soluble color-coating, immediately coolings aid coating, and thereafter applying to the coated side. of said sheet a heated insoluble color coating and immediately cooling said sheet and coating.
6.- A non-curlirig carbon sheet-comprising a carrier sheet, a wax-containing soluble color coating penetrating the carrier sheet, and a separate wax-containing insoluble color-coating applied to the first mentioned coating. 1
