' duplicating ink to Patented July 13, l926.
UNITED STATES PATENT OFFICE.
PAUL GAMIION, OI FOREST-NEAR-BRUSSELS, BELGIUM, ASSIGNOR TO A. B. DICK COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
MANUFACTURE OF STENCILS FOR DUPLIGATING APPARATUS.
No Drawing. Application filed December 12, 1921, Seriatfio. 521,866; and in Belgium December 22, 1920.
This invention relates to the manufacture of stencils for duplicating apparatus, and it has more particularly for its object to provide an improved process for the manufacture of such stencils which will afiord considerable advantages compared with the processes employed hitherto, as will be perceived from the following description.
Stencils as employed hitherto have, as a matter of fact, the following drawbacks 1. A paraflin-coated stencil allows the pass through the cracks that are caused accldentally either through the usual handling, or by the stencil being carried along bythe type-writing machine in which it is being used, at the instant when it is being impressed by the matter that is to be duplicated, Such cracks give rise to ink spots on the copies. v
2. Other kinds of stencils are not subject to the occurrence of the cracks referred to under 1, but they haveto be moistened before being used in the typewriter. This moistening operation hasas its chief drawback, that of causing the parts of the typewriter to become moistened as well, with consequent rusting and deterioration of those parts. A stencil of that kind is not sufficiently thick (that is, has not sufficient body) and is diflicult to keep in correct position on the inking cylinders of rotary and other duplicating machines so that the matter on the stencil is not adapted to produce uniform copies.
The above-mentioned drawbacks are obviated by the present invention which consists broadly in usingas the stencil a sheet of Japanese paper (such as is already in general use in this class of manufacture and commonly known as Yoshino) impregnated uniformly with pharmaceutical or industrial collodion, or a solution of celluloid with an addition of castor oil, and coated on one' side with a coat of paraifin, ceresine wax, or generally with a coat of a solidifiable fatty niineral, vegetable or animal substance.
This last coat is intended to maintain in a supple condition the collodion or solution of celluloid with which the sheet is impregnat'ed; it also serves as a cushion or resilient underlay for facilitating the stencilizing of the coat of collodion or solution of celluloid by the type characters of the typewriter.
It is to be noted that with this object in view the typing should be done on that side of the sheet that is not coated with parafiin.
As a bath having a celluloid basis there may be used a suitable solution of thislatter substance in one of its solvents, or in several 0 of these together, such as ether, acetone, acetic ether, etc., to which solution there is added a certain amount of castor oil or other suitable similar. oil, such that the impregnated sheet shall have the requisite suppleness and thickness. Good results can be obtained by adding approximately 40% of castor oil to a 2 7?) solution of either collodion or celluloid.
A stencil sheet produced according to this invention possesses .body and need not be moistened before being typed upon, and it can crack, and even be creased or rumpled without any ink spots getting upon the co ies.
he same advantages can obviously be obtained, although in a lesser degree by using two sheets one placed upon the other, the first sheet being simply impregnated with collodion or a solution of celluloid, whereas the other sheet is simply coated with para'flin.
Or a single sheet may be used simply 1mpregnated with collodion or a solution of celluloid, and the supporting foundation or underlay being coated with a coat of parafa substance including collodion and castor oil, and, in addition, with a solidifiablematerial.
4-. A type-im ressible stencil-sheet having a base such as Japanese Yoshino coated with a substance including a cellulose compound v 1,cca,aes
and castor oil, and, in addition,with a solidi- 6'. A type-impressiloie stencil-sheet having fiable material applied on oneside thereof. a base such as Japanese Yoshino coated with 5. A type-im ressible stencil-sheet having a substance including a cellulose compound 10 a lease such as apanese Yoshino coated with and castor oil and, in addition, with a waxy 5 a substance including a cellulose compound material applied on one side of said sheet.
and Castor oil, and, in addition, with a waxy In witness whereof I afiix my signature.
