Our invention is principally used in pro! ducin duplicate copies of typewritten matter. heets of paper embodying our invention are treated in such manner that when struck or stamped with a type or other block having a character or design formed thereon in raised portions, the said character or design is indented in the lilin of material thin paper known as 4mate of potash with Which the pape;` ing the loosely feltcd tact. `The paper has-been treated, leaviber of the paper inso treated becomes apex-feet stencil through which printing ink may be forced upon an underlying sheet of paper and produce a perfect facsimile of the original character or design appearing on the type, exactly as though the type or engraved block had been inked in the usual Way and pressed upon the papelin an ordinary pilintingoperation, or any ink ribbon used.
n carrying out our process we take the Japanese paper or other thin paper of similarly loose texture und subject it to treatment with sonic or all of the following solutions: liirst, a solution of from l to 2 ounces of gelatin in about a quart of Weten Second, an ounce of birhrodissolved in about three quarts of Water. Third, amixture of one pint of formaldehyde and one pint of Water. Fourth, a mixture of about i8 ounces of glycerin and 8 ounces of sugar and enough water to fill a quart measure with the solution ythus formed.
The first` solution is preferably formed with hot Water.
rlhe sheet of paper may be l other eolloid, and the secutively, or the last three solutions may be mixed together and the paper dipped in the resulting liquid. Whether some or all of the solutions mentioned are employed, it :is essential that gelatin, or colloid be used` this forming the main body of the coating film to be produced and also that such coating lilm, after deposition, be subjected to the action of a coagulating agent such as an alkaline bichromate, or for- 60 n'laldehyde.A Also, as applicants practice is to carry out that process in daylight, the materials must be separated into at least two solutions, one including the gelatin or ing, the coagulating agent, and that the dipping in, or other treatment by these two solutions, should be successive, treatment with the colloid solutionv being preferably done first. It is evident that if the colloid and the 70 coagulant were mixed in one solution before application to the paper, or if the paper were treated simultaneously with the colloid solution and the coagulating solution, the colloid would be Wholly or before it could be distributed in an even film over the paper, unless the coagulating action were extremely slow) and the coating so formed would be uneven and full ofpin holes. It is therefore advisable per first be treated with the colloid solution, so that it may formA an even, imperforate film or coating thereon, and that this coating Hlm be'subscquently coagulated, or fixed. by treatment with. The iiapfrlmown as Japanese dental paper or Yoshino gives good results. After dipping. the paper is'tlien dried, ortif stencil cards are to be made of it', the paperis laid or otherwise fastened thereto. The solution itself may serve as the cement.

typewriter, preferably provided with the attachment shown in Patent No. 960,252 issued .to Frank D. Belknap June 7, 1910, andthe naine and address of a person, or any other desired matter is written thereon by opcratingz,T the typewriter in the same way as is done in forming ordinary wax paper stencils. When the cards soforined and treated are put through any suitable stencil print-ing apparatus, such as is shown for instance in Patent'No. 889,503, issued to Edwin D. Belknap, the. ink goes through the portions of the paper against which the type faces have struck, and not through the other portions. The result is a perfect printing on thevenvelops or other articles run through the machine concurrently with the cards. The printing so performed can not be distinguished from printing done di rectly by the same typewritiiig machine in the ordinary way. The paper so treated resists the action of the atmosphere, adheres closely to the ordinary cardboard frame, and seems to expand and contract under variations of heat and moisture at about the same rate as the cardboard frame so that the card does not buckle or curl in use.
1We have made many experiments with the ordinary waxed papers on the market in the etlort to make satisfactory stencil cards of this kind, and have experimented with many different solutions and fillers in the eitort to produce an absolutely satisfactory stencil card for use in addressing` machines` but the materials above described are the first to give perfectly satisfactory results. The treated paper is more like a parchment paper than like the ordinary waxed stencil paper.
The coagulated. gelatin or other colloid forms the basis oi? the 'coating film, giving it the necessary strength and colierency, while the glycerin is an example of a. tempering agent which, by its admixture in regulated quantities, prevents the coagulated colloidal films from becoming too hard, or otherwise resisting the displacing pressure of the type to too great an extent.
While the best results are obtained by the treatment with all of the solutions described, less perfect results may be obtained by using some of the materials without the other. The best results are also obtained if ,the stencil sheet is run ,through the typewriter While slightly damp. When the sheet is not stencilized until after it has become dry,
aliases this dainpening may be eiifected by going over the tace of the sheet' with a Wet brush. (lther alkaline hichomates can be substituted i'or the bichromatc of potash particularly above mentioned.
Having, therefore, described our invention, we claim:
