"Specification of Letters Patent.
Patented Aug. 4, 1908.
Application filedJune 17, 1907. Serial .No. 379,505
To allwho'm it may concern:
Be it known that I, WILLIAM F. CLARKE, a citizen of the United States, residing at Louisville, in the' co'unty of Jefferson and State of Kentucky, have invented certain new and useful lmprovements' in TypeVVriter Ribbons for Use in Lithogra hing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and, I use the same. I
My invention relates tolithographic print ing and particularly to transferring direct from the type-written page to stone, zinc or other metals ,or materials, for the purpose of producing printing plates. for the litholithographic press.
graphic or type rinting press.
The object of the invention is to simplify the access now generally in use whereby the work may be done cheaper and much more expeditiously with better results.
One of the processes in general use for making imitation type-written letters consists in setting up type in the ordinary Way, using a peculiar ink known as transfer ink instead of ordinary printers ink and taking the impression on a specially pre ared paper called transfer paper. From tliis impression a transfer is made to the stone and after chemical treatment said stone is ready for the The Well-known photolithographic process consists in photographing a type-written letter on the stone treating this stone photogralph chemically and thus rendering 1t capab e" of being printed from in the lithographic printing machine; As distinguished from these processes, mine consists in preparing a co. on a t ewriter by the use of a speciallgprepared iiibbon and'transfer aper. transferred direct y to the stone, eliminating the setting up of the type as in the first rocess or photographing it as in the photo itho graphicprocess. I I I In the accompanying drawing: Figure 1 is a perspective view on an enlarged scale of a piece-of-satin or nap faced ribbon such as I employ, and Fig. 2 IS a sectional view showing the coatings of silicate of soda and ink which are applied to the napped surface of the ribbon.
'pers may This copy may be this coating is dry, there is placed over it an inky coating 4 which is prepared substantlallv 1n the following manner :Four parts of tallow, twenty-four parts of wax, twenty six parts of castile soap and two parts of Shellac are melted together and when cool form a semi-hard mass which is dissolved in ether or alcohol. Tothis mixture is added a solution of alkanet root or lamp black, or other coloring matter. When this second. coating is dry enough to permit the ribbon to be handled, it ready for use. The copy made on the typewriter from this ribbon may be transferred direct to the stone -which is treated chemically in the same manner as in the old processes.
' The object in coating the ribbon with silicate of soda is to prevent the second coating from penetrating to the reverse side of'the ribbon where it would clog the ty e of the ypewriter. In addition to this, -t e liquid ass forms a smooth surface which readily releases a ort-ion of the film formed by the second or atty coating which easily adheres to the paper as the letters are struck on the typewrlter. Any'of the known transfer pabe used on the typewriter for preparing t e co y with my new ribbon. It should lib understood that either surface printing or relief printingmay be done by transferring from my ribbon, the difference'being'in. the'treatment of the printing surface after the transfer has'been made. As is well in-the art of lithogra hy, stone, zinc and aluminium are used or surface printing bychemic'al action lwhile zinc is used or relief printin and takes up the ink mecluanically.v Sai zinc (plates are brought to IUD transferred to stone it will be absorbed without spreading and will stand the chemical treatment which the lithographic process requires. .If the ribbons are used a few da s after they are prepared or are kept in tig t boxes until they are used, the results will be found to be very satisfactory.
The satin or nap surface of theribbon produces a smoother and more evenimpression on the transfer paper than is obtained when an ordinary typewriter ribbon is used. The smooth but absorbent nap surface readily takes and holds the thin coating of silicate of soda leaving the ribbon sufficiently pliable for use on the ty ewriter and furthermore overcomes thebro en orwhite line effect and the reproduction"of-'the texture of the ribbon on the face of the letters when they are struck on the transfer paper. ordinary ribbon may be overloaded with transfer ink so that the texture will not be seen in the impression, in that case the body While an of ink is so great that it spreads when transferred and the letters fill up and run together.
I claim:
1. A typewriter ribbon, for the purpose specified, coated with silicate" of soda and over it a coating of transfer ink.
2. A type-writer ribbon forrthe purpose specified, com rising a silk ribbon, having a nap on one Sir e, said nap side being coated with transfer ink.
3. A typewriter ribbon for the purpose specified, comprising a silk ribbon, having a nap. on one side, said nap side being coated :r
first with silicate of soda and then with trans fer ink.
In testimony whereof, I affix my signature,
in presence of two witnesses.
