ROLAND H. SMITH, OF PITTSBURG, PENNSYLVANIA PRODUCTION OF HEKTOGRAPHS.
SPECIFICATION forming part of Letters Patent No. 342,142, dated May 18, 1886.
Application filed June .24, 1885.
To all whom, it may concern:
Be it known that I, ROLAND H. SMITH, a citizen of the United States, residing at Pitts burg, in the county of Allegheny and State of Pennsylvania. have invented certain new and useful Improvements in the Production of U character.
Hektographs, of which the following is a speci fication, reference being had therein to the accompanying drawing.
My invention relates to improvements in the manner or method ofproducing copyingsheets for multiple copies, and is designed to produce a device of cheap and simple construction for the purpose.
In setting forth the method reference is had to the annexed drawing, representing a perspeetive view of the finished article produced by the said method, and aiding in specifying the various steps of the process.
The first step of my process is to heat a sheet or sheets of paper, the kind making no diiference,or asheetorsheets of cloth. The pa per is used for small copiessuch as let-ters while the cloth is used for large copies of any The second step is to place or flow upon the heated sheet or sheets the hektograph material until a thin even surface is obtained. The said material may be placed upon the sheet and the heat then applied till the desired surface is obtained. WVhen cool, and the hektograph surface sufficiently solid, I then place upon it asheet of thin or tissue paper first saturated with wax or glycerine or other similar substance, glycerine having been found to give the best results. The sheets, each of which forms a perfect hektograph, may then be packed for shipment, or bound Serial No. 169,636. (No model.)
into books,forming,if they may be so called, reproducing letter-books. The waxed or similarly-prepared paper or equivalent substance thoroughly protects the hektograph -surface and prevents one sheet sticking to the other, while not interferingwith the said surface, it being removed and replaced at pleasure. Neither the hektograph material nor the ink used thereon will adhere to the waxed or oiled paper.
The surface may be washed and a new copy prepared, though the cheapuess of the prepared sheets will admit of their being kept for reference and future copiesof the one impression, and new sheets used for new copies. This is one of the most important points and ad vantages of the invention.
Referring to the drawing, A represents the paper or cloth sheet, 13 the hektograph-sur- ROLAND H. SMITH.
